The number of pounds of blueberries and grapes sold are 11 and 22.
According to the statement
we have given that the:
Each pound of blueberries sells for $2.50 and each pound of grapes sells for $1.25.
And total money collected by selling pounds is $55
And total number of pounds sells = 33
And we have to find the Number of pounds of blueberries and grapes.
Let the number of pounds of blueberries is X
And Let the number of pounds of grapes is Y
So,
The equation becomes is:
X + Y = 33 -(1)
2.50X + 1.25Y = 55 -(2)
Now, From substitution method
From (1) equation
Y = 33 - X
put these in equation (2) then
2.50X + 1.25(33 - X ) = 55
2.50X + 41.25 - 1.25X = 55
1.25X = 13.75
X = 11
and the the value of Y becomes
Y = 33 - X
Y = 33 - 11
Y = 22.
So, The number of pounds of blueberries and grapes sold are 11 and 22.

Donna is thinking about buying a house that costs $125,000. If she puts down $25,000 and is able to get a 5 percent mortgage, she wants an estimate of her total monthly housing expenses. The average annual cost for owning a house, beyond the 5% cost of mortgage interest, is 4.09 percent of the value of the house. Not including the opportunity cost of the down payment, amortization on the loan, or any tax benefits from homeownership, what will be her monthly cost the first month?
A. $206.25
B. $279.60
C. $842.71
D. $746.43
Donna can expect her total monthly housing expenses to be approximately $842.71 for the first month after purchasing the house, assuming no tax benefits or amortization on the loan.
To calculate Donna's monthly housing expenses, we first need to determine the total amount of the mortgage. Since she puts down $25,000 on a $125,000 house, she will need to take out a mortgage for $100,000.
Next, we can calculate the annual cost of owning the house beyond the 5% cost of mortgage interest, which is given as 4.09% of the value of the house. So, 4.09% of $125,000 is:
0.0409 x $125,000 = $5,112.50
This means that Donna can expect to pay approximately $5,112.50 per year in additional expenses associated with owning the house.
To calculate the monthly cost, we simply divide this by 12:
$5,112.50 / 12 = $426.04
So, Donna can expect to pay approximately $426.04 per month in additional expenses associated with owning the house.
Adding the cost of the mortgage interest, we can calculate her total monthly housing expenses as follows:
Total monthly housing expenses = Mortgage interest + Additional annual costs / 12
Mortgage interest = 5% of $100,000 = $5,000 per year or $416.67 per month
Total monthly housing expenses = $416.67 + ($5,112.50 / 12) = $416.67 + $426.04 = $842.71
Hence, Donna can expect her total monthly housing expenses to be approximately $842.71

the third term of an arithmetic sequence is 7 and the twelfth term in 106. what is the one hundredth term of the sequence
Answer:
a₁₀₀ = 1074
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₃ = 7 and a₁₂ = 106 , then
a₁ + 2d = 7 → (1)
a₁ + 11d = 106 → (2)
solve the equations simultaneously to find a₁ and d
subtract (1) from (2) term by term to eliminate a₁
(a₁ - a₁) + (11d - 2d) = 106 - 7
0 + 9d = 99
9d = 99 ( divide both sides by 9 )
d = 11
substitute d = 11 into (1) and solve for a₁
a₁ + 2(11) = 7
a₁ + 22 = 7 ( subtract 22 from both sides )
a₁ = - 15
Then
a₁₀₀ = - 15 + (99 × 11) = - 15 + 1089 = 1074

Use the figure to answer the following.
a. What is the surface area of the cylinder? Leave your answer in terms of x.
b. Suppose the diameter and the height of the cylinder are cut in half. How does this affect the surface area of the cylinder? Explain
The diameter of the cylinder is 8 and the height is 11
a. The surface area of the cylinder is 120π square units.
b. Assuming the diameter and the height of the cylinder are cut in half, the surface area of the cylinder would be reduced by a scale factor of 1/4.
How to calculate surface area of a cylinder?In Mathematics and Geometry, the surface area (SA) of a cylinder can be calculated by using this mathematical equation (formula):
SA = 2πrh + 2πr²
Where:
h represents the height.r represents the radius.Note: Radius = diameter/2 = 8/2 = 4 m.
By substituting the side lengths into the formula for the surface area (SA) of a cylinder, we have the following;
Surface area = 2πrh + 2πr²
Surface area = 2(π)(4)(11) + 2(π)(4²)
Surface area = 120π square units.
Part b.
Assuming the diameter and the height of the cylinder are cut in half, we have:
Surface area = 2(π)(4/2)(11/2) + 2(π)((4/2)²)
Surface area = 2(π)(2)(5.5) + 2(π)(2²)
Surface area = (π)(2)(11) + 2(π)(4)
Surface area = 22π + 8π
Surface area = 30π square units.
Scale factor = 30π/120π
Scale factor = 1/4.

porfaaa
Luis traveled approximately 31,736.8 inches on his bicycle.
We have,
To find the distance that Luis traveled on his bicycle, we need to calculate the circumference of the tires and then multiply it by the number of complete turns.
Given:
Radius of the tires (r) = 20p (2.54) inches
Number of complete turns (n) = 50
The circumference of a circle can be calculated using the formula:
Circumference = 2πr
Substituting the given radius into the formula, we have:
Circumference = 2π * (20p) inches
Now we can calculate the distance traveled (d):
Distance = Circumference x Number of complete turns
Distance = 2π x (20p) x 50 inches
To simplify the calculation, we can approximate π as 3.14:
Distance ≈ 2 x 3.14 x (20 x 2.54) x 50 inches
Calculating this expression, we find:
Distance ≈ 31736.8 inches
Therefore,
Luis traveled approximately 31,736.8 inches on his bicycle.

What is the interquartile range for data set? 27,4,54,78,27,48,79,64,5,6,41,71
The Interquartile range for the given data set is 51.
The interquartile range for a given data set, the values of the first quartile (Q1) and the third quartile (Q3). The interquartile range is the difference between Q3 and Q1.
First, let's arrange the data set in ascending order:
4, 5, 6, 27, 27, 41, 48, 54, 64, 71, 78, 79
To find Q1, which represents the lower quartile, we need to locate the median of the lower half of the data set. Since the data set has 12 values, the lower half consists of the first 6 values:
4, 5, 6, 27, 27, 41
The median of this lower half is the average of the middle two values, which are 6 and 27:
Q1 = (6 + 27) / 2 = 33 / 2 = 16.5
To find Q3, the upper quartile, we need to locate the median of the upper half of the data set. Again, since the data set has 12 values, the upper half consists of the last 6 values:
48, 54, 64, 71, 78, 79
The median of this upper half is the average of the middle two values, which are 64 and 71:
Q3 = (64 + 71) / 2 = 135 / 2 = 67.5
Finally, we can calculate the interquartile range by subtracting Q1 from Q3:
Interquartile range = Q3 - Q1 = 67.5 - 16.5 = 51
Therefore, the interquartile range for the given data set is 51.

[tex]\boxed{\begin{minipage}{5.5cm}\underline{Apothem of a regular polygon}\\\\$a=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\where:\\\phantom{ww}$\bullet$ $s$ is the side length.\\ \phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}[/tex]
Substitute n = 12 and a = 5 into the equation to create an expression for s:
[tex]5=\dfrac{s}{2 \tan \left(\dfrac{180^{\circ}}{12}\right)}[/tex]
[tex]s=10\tan \left(15^{\circ}\right)[/tex]
Now we can use the standard formula for an area of a regular polygon:
[tex]\boxed{\begin{minipage}{6cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{n\cdot s\cdot a}{2}$\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the length of one side.\\ \phantom{ww}$\bullet$ $a$ is the apothem.\\\end{minipage}}[/tex]
Substitute the found expression for s, n = 12 and a = 5 into the formula and solve for A:
[tex]A=\dfrac{12 \cdot 10\tan \left(15^{\circ}\right) \cdot 5}{2}[/tex]
[tex]A=\dfrac{600\tan \left(15^{\circ}\right)}{2}[/tex]
[tex]A=300\tan \left(15^{\circ}\right)[/tex]
[tex]A=80.3847577...[/tex]
[tex]A=80.4\; \sf square\;units\;(nearest\;tenth)[/tex]
Therefore, the area of a regular dodecagon with an apothem of 5 units is 80.4 square units, rounded to the nearest tenth.
Select the values that are solutions to the inequality x2 + 3x – 4 > 0.
Answer: To solve the inequality x^2 + 3x - 4 > 0, we can use the method of factoring.
First, we can factor the quadratic expression:
x^2 + 3x - 4 = (x + 4)(x - 1)
Now we can find the values of x that make the expression greater than zero by looking at the sign of the expression for each factor and applying the sign rules of multiplication:
If both factors are positive, the expression is positive.If both factors are negative, the expression is positive.If one factor is positive and one factor is negative, the expression is negative.
Using this method, we can create a sign chart:
x x + 4 x - 1 x^2 + 3x - 4
-4 0 -5 +6
-1 + - -
1 + + +
0 + - -
2 + + +
From the sign chart, we can see that the expression is greater than zero for x < -4 or x > 1. Therefore, the solutions to the inequality are all real numbers x such that x < -4 or x > 1. We can write this as:
x < -4 or x > 1
Solve: log 3 (3x) + log 3 (3) = 5
Answer: x=27
Step-by-step explanation:
Assumption the 3's are the bases
[tex]log_{3} 3x +log_{3} 3=5[/tex] >combine using multiplication log rule (logs with
same base, that are being added can be
combined with multiplication)
[tex]log_{3}( 3x)(3) =5\\[/tex] >simplify
[tex]log_{3}( 9x) =5\\[/tex] >rewrite into exponent form

243 = 9x
x=27
Answer:
x = 27
Step-by-step explanation:
using the rules of logarithms
• [tex]log_{b}[/tex] b = 1
• [tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
then
[tex]log_{3}[/tex] (3x) + [tex]log_{3}[/tex] 3 = 5
[tex]log_{3}[/tex] (3x) + 1 = 5 ( subtract 1 from both sides )
[tex]log_{3}[/tex] (3x) = 4
3x = [tex]3^{4}[/tex] = 81 ( divide both sides by 3 )
x = 27
The graph of a sine function has an amplitude of 4, a midline of y=2, and a period of 10.
There is no phase shift. The graph is reflected over the x-axis.
What is the equation of this function?
The equation of the given sine function is y = 4 × sin((π/5)x) + 2.
The equation of the given sine function can be determined based on the given information. We know that the general form of a sine function is:
y = A × sin(Bx - C) + D,
where A represents the amplitude, B represents the frequency, C represents the phase shift, and D represents the vertical shift.
In this case, we are given the following information:
Amplitude (A) = 4: The amplitude is the distance between the maximum and minimum values of the function. Since the function is reflected over the x-axis, the amplitude is positive 4.
Midline (D) = 2: The midline is the horizontal line around which the graph oscillates. In this case, it is y = 2, indicating a vertical shift of 2 units upwards.
Period = 10: The period is the distance between two consecutive peaks (or troughs) of the function.
Given that there is no phase shift, the phase shift (C) is 0.
From the given information, we can deduce the values of A, B, C, and D to construct the equation.
A = 4 (amplitude)
D = 2 (vertical shift)
C = 0 (no phase shift)
To determine B, we use the formula:
B = 2π / Period
Plugging in the value for Period (10), we can calculate B:
B = 2π / 10 = π / 5
Therefore, the equation of the given sine function is:
y = 4 × sin((π/5)x) + 2.

Sobre una embarcación de 160 kg que está en reposo con su proa apuntando a la orilla, comienza a caminar una persona de 70 kg desde la proa hacia la popa, a 0.80 m/s respecto a la embarcación. ¿Cuáles son las velocidades de la embarcación y de la persona respecto a la orilla? Desprecia la resistencia del agua al movimiento.
The velocities of the boat and the person relative to the shore are 1.337 m/s and 2.896 m/s, respectively.
How to calculate the velocityWe can use the conservation of momentum equation:
(mboat + mperson) * vboat = mperson * vperson
(160 kg + 70 kg) * vboat = 70 kg * (0.80 m/s + vperson)
230 kg * vboat = 56 kg * (0.80 m/s + vperson)
vboat = (56/230) * (0.80 m/s + vperson)
vperson = 0.80 m/s + vboat
vperson = 0.80 m/s + (56/230) * (0.80 m/s + vperson)
(174/115) * vperson = (504/115) * m/s
Dividing both sides by (174/115), we get:
vperson = 2.896 m/s
vboat = (56/230) * (0.80 m/s + vperson)
Substituting the value of vperson, we get:
vboat = 1.337 m/s
