Matthew is going on a trip to Hawaii and takes a limo to the airport. The driver says it will cost $20 plus 12 cents a mile. Matthew lives 50 miles from the airport. please hurry to answer
Answer:
$26
Step-by-step explanation:
Step one:
given data
cost of limo=$20
cost per mile= 12cent to dollar = $0.12
Step two:
let the total cost be y
and the number of mile be x
the model for the situation is
y=mx+c
Step three:
given x=50mile
y=0.12(50)+20
y=6+20
y=26
$26
Matthew will spend $26 to get to the hospital
1/3 minus 1/6 equals to???
Answer:
1/6
Step-by-step explanation:
In order to add or subtract fractions you have to have the same denominator for both factions. you do this through finding the Lowest Common Denominator (LCD) In this case it's six because both 3 and 6 (the denominators) can go into 6. So turn 1/3 into a fraction with 6 as the denominator through multiplying both the top and bottom of the fraction by 2
1/3 * 2/2 = 1*2/3*2 = 2/6
Then you can straightforwardly subtract
2/6 - 1/6 = 1/6
Express the ratio below in its
simplest form.

Solve for y.
C=8(y + k)
Answer:
C/8 -k= y
Step-by-step explanation:
C=8(y + k)
Divide each side by 8
C/8 = y+k
Subtract k from each side
C/8 -k = y+k-k
C/8 -k= y
Answer: y = C /8 − k

What’s the volume of this shape?
Answer:
V=72x³y³
Step-by-step explanation:
The formula to apply is;
V= l * w * h where
V= volume in units cubed.
l= length = 3xy
w=width = 4xy
h= height = 6xy
Substitute values in the formula as;
V= l*w*h
V=3xy * 4xy * 6xy ----find product for the numbers {3*4*6=72} then multiply by the product for x's {x*x*x =x³} that of y's {y*y*y=y³}
V= 72*x³*y³
V= 72x³y³ --------where xy are the units used.

Step-by-step explanation:
Lucas scored 75, 78, 82, and 84 on his four algebra tests. There is one test remaining in the grading period. Lucas's homework average is 95. His teacher will count each test score and the homework average as one-sixth of Lucas's final grade. NEED THIS ANSWER NOWWWWWWWW
Answer:
Step-by-step explanation:
Let Lucas final grade be x
All Lucas grade will be 75, 78, 82, and 84 and x.
Average score = 95
Since we are not told what to look for, we can find the Lucas final grade.
Using the formula for calculating mean (average)
Mean = Sum of the score/total test taken
95 = 75+78+82+84+x/5
95 = 319+x/5
Cross multiply
95×5 = 319+x
475 = 319+x
x = 475-319
x = 156
Lucas final grade is 156
One sixth of Lucas final grade = 1/6 × 156 = 26

HELP ME 10 points I NEED HELP TIMED
A line passes through the points (8,-1) and (-4, 2).
What is the y-intercept of this line?
-4
-1
1
4 ?????!
Answer:
y = (-1/4)x + 1 so that the y-intercept is 1
Step-by-step explanation:
The slope is (-1 - 2)/[8 - (-4)] = -3/12 = -(1/4)
(-1/4) = (y - 2)/(x + 4) => -x - 4 = 4y - 8
-x + 4 = 4y
y = (-1/4)x + 1 so that the y-intercept is 1

Elena is making an open-top box by cutting squares out of the corners of a piece of paper that is 11 inches wide and 17 inches long, and then folding up the sides. If the side lengths of her square cutouts are inches, then the volume of the box is given by V(x)=x(11-2x)(17-2x)
Answer:
Step-by-step explanation:
Refer the attached picture for complete question
a) V(x)=x(11-2x)(17-2x)
B(x)=140
Side and volume cannot be negative
So, x> 0
11-2x>0 and 17-2x>0
[tex]x<\frac{11}{2}[/tex] and [tex]x< \frac{17}{2}[/tex]
Domain for V(x) :[tex]0<x<\frac{11}{2}[/tex]
b)For finding the greatest Volume
[tex]\frac{dV}{dx}=0[/tex]
[tex]V(x)=x(11-2x)(17-2x)=4x^3-56x^2+187x[/tex]
[tex]\frac{dV}{dx}=12x^2-112x+187=0\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{112\pm\sqrt{(112)^2-4(12)(187)}}{2(12)}[/tex]
x=7.155 , 2.177
Consider the graph
So, Volume at 7.155 is negative
Thus x≈2 gives the greatest volume
c)
Consider the graph .
It is increasing from [tex]-1 \leq x \leq 2[/tex] and [tex]x \geq 7[/tex]
So, Graph increasing interval is [-1,2] ∪[7,∞)
d)
At the point of intersection, both graph has the same value .
The members of the Math team contributed a total of $9.10 for the party after their practice. Each member contributed the same amount of money in dimes only. How many members are in the team and how much money did everyone contribute? Give all possible answers.
Answer:
Number of possibilities
1) 91 members that contribute 1 dime each ($0.10)
2) 13 members that contribute 7 dimes each ($0.10 × 7 = $0.70)
3) 70 members that contribute 13 dimes each ($0.10 × 13 = $0.13)
Step-by-step explanation:
A dime = $0.10 in dollars
We are told that:
The total amount contributed = $9.10 for the party after their practice.
Each member contributed the same amount of money in dimes only.
Let the number of members be represented as: x
Number of possibilities
We find the factors of $9.1
= 1, 0.7, 0.13, 9.1
= 1 × 9.1
= 0.7 × 13
= 0.13 × 70
Hence:
1) $0.10 × x = $9.10
x = $9.10/$0.10
x = 91
Therefore, from the calculation above, there are 91 members and each of them contributed the same amount which was 1 dime ($0.10).
2)
7($0.10 )× x = $9.10
x = $9.10/$0.70
x = 13
Therefore, from the calculation above, there are 13 members that contribute 7 dimes each ($0.10 × 7 = $0.70)
3) 13($0.10) × x = $9.10
x = $9.10/$0.13
x = 70
Therefore, from the calculation above, there are 70 members that contribute 13 dimes each ($0.10 × 13 = $0.13)

If the point (6, 9) is on the graph of an even function, what other point must also be on the graph?
Answer:
b/c it's an even function you know that f(x) = f(-x) too so whether you put in a positive X or a negative X you get the same answer so you know.. that (-6,9) is also on the graph of this function
Step-by-step explanation:
Given that the function is even and we know that (6, 9) is on its graph, we know that (-6, 9) must also be on the graph.
Even functions:
A function f(x) is even if:
f(x) = f(-x)
Now, we know that the point (6, 9) is on the graph of our function, this means that:
f(6) = 9
And because our function is even, we must have:
f(6) = f(-6) = 9
Then the point (-6, 9) must also be on the graph of the function.

Describe what the intercepts mean in context of the story.
Answer:
wow they are so tricky about what the math means.. huh :D why ask abstract math questions when it's supposed to be real hmmmm welll anyway
Step-by-step explanation:
so the y intercept or 0=y means you get your dog no treats... maybe you hate your dog... or he was bad in some way... no treats for you dog !! >:/
The X=0 intercept mean you love your dog and don't take him to the dog kennel but keep him at home. And take care of him yourself.. but you could still get him treats :) Probably for less then 5 dollars too.. I saw some at Costco for a lot less.. :)

If A = –2x + 8 and B = 2x – 4, find an expression that equals 2 A + B
in standard form.
Answer:
Answer: -2x+12
Step-by-step explanation:
So, it says the expression equals 2A + B. That means you need to multiply the equation for A by 2 and then add the equation of B to it. The question is asking you to write it in standard form. It would look like this:
2(-2x+8) + 2x-4
-4x+16+2x-4

Step-by-step explanation:
We know that it costs 37 cents to mail a letter that weighs 1 oz or less. This would mean that for x ≤ 1, P(x) should equal 37. Already, we can eliminate A and D.
We also know that it costs an additional 26 cents for at most another ounce added to the original 1 ounce. This means that for 1 < x ≤ 2, P(x) = 26 + 37 = 63. This is shown by B.
Thus, the answer is B.
