A design for a garden is composed of a triangle and 2 rectangles. Some side lengths of the garden design are shown. 7.5 ft 12.5 ft 7.5 ft 12.5 ft What is the area of the garden in square feet?
Answer:
215.625 square feet.
Step-by-step explanation:
The best way to approach this is by finding the area of each shape and then adding them together.
The area of a rectangle is Length · Width. Both rectangles have a length of 12.5 feet and a width of 7.5 feet. 12.5 · 7.5 = 93.75. And since both rectangles have the same dimensions, we can just multiply 93.75 by two to get 187.5 square feet for the rectangles.
The area of a triangle is Base · Height / 2. Since the sides of the triangle are the same as the sides of rectangles, the dimensions of the triangle are 7.5 feet and 7.5 feet.
7.5 · 7.5 / 2 = 28.125 square feet.
187.5 + 28.125 = 215.625 square feet.

¿ A que distancia se encuentran dos masas de 60 kg y 80 kg, si la fuerza de
atracción entre ellas es de 3x10-31N.
Teniendo en cuenta la Ley Universal de la Gravitación, la distancia a la que se encuentran dos masas de 60 kg y 80 kg, si la fuerza de atracción entre ellas es de 3×10⁻³¹ N, es 1.033 ×10¹² m.
Ley Universal de la GravitaciónLa Ley Universal de la Gravitación establece que los cuerpos, por el simple hecho de tener masa, experimentan una fuerza de atracción hacia otros cuerpos con masa, llamada fuerza gravitacional.
Esta ley dice que la fuerza gravitacional entre dos cuerpos es directamente proporcional al producto de sus masas e inversamente proporcional al cuadrado de la distancia que los separa.
Matemáticamente se expresa de la siguiente manera:
[tex]F=G\frac{Mm}{d^{2} }[/tex]
donde:
G es la constante gravitatoria universal, con un valor de 6,67×10⁻¹¹[tex]\frac{Nm^{2} }{kg^{2} }[/tex].M y m son las masas de los cuerpos que interactúan.d es la distancia que los separa.Distancia entre dos masasEn este caso, sabes:
F= 3×10⁻³¹ NM= 60 kgm= 80 kgReemplazando en la Ley Universal de la Gravitación:
[tex]3x10^{-31}N =6,67x10^{-11}\frac{Nm^{2} }{kg^{2} } \frac{60 kg x80 kg}{d^{2} }[/tex]
Resolviendo:
[tex]\frac{3x10^{-31}N}{6,67x10^{-11}\frac{Nm^{2} }{kg^{2} }} = \frac{60 kg x80 kg}{d^{2} }[/tex]

[tex]d^{2} x4,4977x10^{-21} \frac{kg^{2} }{m^{2} } =4800 kg^{2}[/tex]
[tex]d^{2} = \frac{4800 kg^{2} }{4,4977x10^{-21} \frac{kg^{2} }{m^{2} } }[/tex]
[tex]d = \sqrt{\frac{4800 kg^{2} }{4,4977x10^{-21} \frac{kg^{2} }{m^{2} } }}[/tex]
[tex]d = \sqrt{1,0672x10^{24} m^{2} }[/tex]
d= 1.033 ×10¹² m

what are the slope and y - intercept of the equation 6x+3y=-12
Answer:
Slope= -2
y-intercept= -4
Step-by-step explanation:
To find the slope and y-intercept of a given equation, first rearrange the equation such that it is in the slope-intercept form. In the slope-intercept form, the coefficient of y is 1 and the rest are moved to the left hand side of the equation.
[tex]\textcolor{steelblue}{\text{Slope-intercept form}}[/tex]
y= mx +c, where m is the slope and c is the y-interceptGiven equation: 6x +3y= -12
Let's leave the y term on the left of the equation and bring the rest to the right.
3y= -6x -12
To ensure that the coefficient of y is 1, divide both sides by 3.
y= -2x -4
The equation is now in the slope-intercept form.
The slope is the coefficient of x (the number that comes before x), thus the slope is -2. The y-intercept is -4.
ixl math question im very lazy and i dont understand
Answer:
1/21
Step-by-step explanation:
We start with 7 cards. The probability of picking a 4 is 1/7. Since the first card is not put back, there are 6 cards left. Of these 6 cards, there are two which have divisors of 63: 3 and 7. So the probability of picking a divisor of 63 is 2/6, which reduces to 1/3. Multiplying these probabilities gives 1/21.
Solve the system of equations at right. 2^(x+y)=16 2^(2x+y)= 1/8
Answer:
(x, y) = (-7, 11)
Step-by-step explanation:
The system of exponential equations can be solved by the use of logarithms. Equivalently, the equations can be written so that exponents can be equated. This system is equivalent to two linear equations.
First equation:
2^(x+y) = 16
2^(x +y) = 2^4 . . . . use the same base to write the constant
x +y = 4 . . . . . . . . equate exponents of 2 (take log₂ of both sides)
Second equation:
2^(2x +y) = 1/8
2^(2x +y) = 2^(-3) . . . . use the same base to write the constant
2x +y = -3 . . . . . . equate exponents of 2
Solve the linear equations:
We can subtract the first equation from the second to get ...
(2x +y) -(x +y) = (-3) -(4)
x = -7
y = 4 -x = 4 -(-7) = 4 +7 = 11 . . . . use the first equation to find y
The solution to the system is (x, y) = (-7, 11).

Answer:
(5,1)
is one of infinitely many possible order pairs.
Step-by-step explanation:
There are an infinite amount of x values that give you an answer to this question. You get to choose. But first let's start off with isolating y.
[tex]-x + 6y = 1\\6y = 1 + x\\y = \frac{1+x}{6}[/tex]
Now the equation is easier to interpret. [tex]y = \frac{1+x}{6}[/tex]
Now here's the part where you actually get to choose. Take any x, value, I'll choose 5.
I'll sub it into the equation and get my y value, [tex]y = \frac{1 + (5)}{6}= 1[/tex]
Okay, we get that y = 1, when x = 5. That's an ordered pair:
(5,1)
Remember you could follow this same procedure for any x value you choose.

Find the mean and median scores.
Answer:
the median is 3.5
Step-by-step explanation:
there are 27 dots 27/2=13.5 therefore the answer is the 13th dot and a half 3.5 :) (i dont know for sure but i think the mean is 3)
The mean is 3 and the median is 3 for this list of numbers.
From the dot pot,
Arrange the number in order:
1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5
Now,
Mean = Average of all the values.
Median = Midvalue of the number.
Now,
There are 30 numbers in the list, so the mean is:
Mean = 90/30 = 3
To find the median, we need to find the middle number.
Since there are an even number of numbers in the list, we take the average of the two middle numbers:
The middle two numbers are both 3, so the median is:
Median = (3 + 3)/2 = 3
Therefore,
The mean is 3 and the median is 3 for this list of numbers.

Find the value of x. Round to the nearest tenth of a unit. Show work.
Answer:
x = 41.16
Step-by-step explanation:
The value of the top angle in the triangle is equal to 90° - 27° = 63° as they are complementary anglesTo find x, take the tan ratio of the angletan63° = 1.96tan63° = x/21⇒ x/21 = 1.96⇒ x = 21 * 1.96⇒ x = 41.16Answer:
x=41.2
Step-by-step explanation:
Assuming that the dotted line and the vertical line form a 90 degree angle, we can find the angle measurements of the triangle.
Since there is a 90 degree angle formed between the dotted line and the vertical line, subtracting 27 from 90 will get us the angle measure of one of the vertex of the triangle.
90-27=63 degrees
Now we can use trig. ratios to help us figure out the missing side.
tan(63)=x/21
x=tan(63)*21
x=41.21482062
x=41.2

Which inequality is shown in the graph?

Step-by-step explanation:
please solve this question faaaast
Answer:
300-400
Step-by-step explanation:
The first step is finding the total of the data we have. So, we take 5 + 10 + 15 + 20 + 25 + 15 + 10 which equals 80.
The median is the middle point of all the data. If it's an odd number, you can calculate the median with the equation (n+1) / 2, plugging in the total amount of data for n.
When it's an even number though, there is no one middle point since the data splits evenly in 2, so we have to use 2 equations: n/2 & (n/2) + 1. Then, we find the average of those two data points. (Although, you don't have to do that for this particular question).
When we plug 80 in for n in both of these equations, we get 40 and 41.
To where this is in the question, we have to count up from the bottom of the chart. 1-5 is below 100, 6-15 is 100-200, 16-30 is 200-300, and 31-50 is 300-400.
Since 40 and 41 are between 31 and 50, the answer is 300-400.

plug (equation 4)'s value of x into (equation 1)

Thus the answer is [tex]y = (x-4)^2 -4[/tex]
