Answer:
$11.36 (11 dollars and 36 cents).
Step-by-step explanation:
This scenario can be written as the linear equation: y = -$0.16x + $20 Where y is the remaining credit, and x is the minutes spend calling.
To find the remaining credit after 54 minutes,
substitute 54 for x and simplify.
So y = -$0.16(54) + $19.60 = -$8.64 + $20.00 =
$20.00 - $8.64 = $11.36.

If you want to solve this problem from scratch, first find the constant rate of money by subtracting 30 minutes (time) over $15.20(total) by 46 minutes over $12.64(total).
Just subtract across, and simplify to get the rate, and then apply that rate between the missing total of 54 minutes and the total of $12.64 dollars for 46 minutes. This is because rate = change quantity/change in time. If that rate is constant as it is in this relationship where the quantity is the amount of anything that is dependent on something, in this case it's money.
So subtract (find the difference) to find the pattern of change between these values in respect to time.
15.20/ 30 - 12.64 / 46 = 2.56 / -16 = 1.28 / -8 = 0.64 / -4 = 0.32 / -2 = 0.16 / -1 = -0.16 [This is the rate decrease in money every minute of a call being made or decrease in remaining credit every minute ].
Now since we know the rate, we can solve the missing factor of the problem by multiplying the rate by the change in time to get the change in quantity.
So : 54 - 46 = 8. 8 × 0.16 = 1.28 [This is the change in quantity from 46 to 54 minutes of calling ].
Therefore, $12.64 [remaining credit from 46 minutes ] - $1.28 [the change of credit from 46 minutes to 54] = $11.36 [remaining credit from 54 minutes].
Also in general, Rate = dependent variable / independent variable.
What is the approximate length, in centimeters, of the diagonal from point A to point B in the right rectangular prism shown? Round your answer to the nearest whole centimeter.
A.8
B.9
C.10
D.11
Answer:
11
Step-by-step explanation:
First, find the diagonal along the base of the prism. Let B be the diagonal along the base.
8^(2)+6^(2)=b^(2)
64+36=b^(2)
100=b^(2)
10=b
Then let d be the diagonal from point A to point B
b^(2)+5^(2)=d^(2)
10^(2)+5^(2)=d^(2)
100+25=d^(2)
125=d^(2)
\sqrt(125)=d
11=d

The flu is starting to hit Weston. Currently, there are 380 people infected, and that number is growing at a rate of 15% per day. Overall, how many people will have gotten the flu in 7 days? If necessary, round your answer to the nearest whole number.
Answer:
1011 or 1010, depending on how you round. (I got 1011)
Explanation:
we need to calculate 15% of the non-constant x seven times.
x starts as 380.
15%=0.15
15% of x seven times:
380*0.15=57,
380+57=437;
437*0.15= 65.55,
437+65.55= 502.55;
502.55*0.15=75.38,
502.55+75.38=577.93;
577.93*0.15=86.69,
577.93+86.69=664.62;
664.62*0.15=99.69,
664.62+99.69=764.31;
764.31*0.15=114.65,
764.31+114.65=878.96;
878.96*0.15=131.84
878.96+131.84= 1011

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long. Each president's picture is 6 inches wide. If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?
Answer:
8 pictures
Step-by-step explanation:
Given
[tex]Window = 5\frac{3}{4}ft[/tex]
[tex]Wall = 9.75ft[/tex]
[tex]Pictures = 6\ inches[/tex]
Required
Determine the number of pictures
First, we need to calculate the length of the available space
This is calculated by subtracting the width of the window from the width of the wall.
[tex]Space = Wall - Window[/tex]
[tex]Space = 9.75 - 5\frac{3}{4}[/tex]
Convert fraction to decimal
[tex]Space = 9.75 - 5.75[/tex]
[tex]Space = 4ft[/tex]
Since, the pictures are placed side by side.
This means that, there's no empty space between them.
Number of pictures is:
[tex]Number = \frac{Space}{Pictures}[/tex]
[tex]Number = \frac{4\ ft}{6\ in}[/tex]
Convert feet to inches
[tex]Number = \frac{4 * 12\ in}{6\ in}[/tex]
[tex]Number = \frac{48\ in}{6\ in}[/tex]
[tex]Number = \frac{48}{6}[/tex]
[tex]Number = 8[/tex]
Hence, 8 pictures can fit the wall
Answer:
8 pictures

B. 7/9 and 0.7
Step-by-step explanation:
Since 7 is inside the box that means 7 is being divided by 9 so 7/9, which eliminates C and D.
Since there are infinite more 0s in 7.000, there will be infinitely more 7s when you continue to try and divide. which means there must be a little line above the 7 in the 0.7, so the answer is B

Callie solved this one-variable equation. When she was done, she tried to verify her answer, but found that it was wrong. Can you find her mistake? 1 2 (4k + 8) = 10 1. 2k + 16 = 10 2. 2k = −6 3. k = −3 What was Callie’s mistake? Callie should have added 10 to both sides in step 2. In step 1, when Callie distributed the One-half to the 8, she multiplied incorrectly. Callie divided by 2 instead of multiplying by 2 in step 3. Callie should have added 16 to both sides in step 2.

10 bags of chips and 8 soda cans cost $15.
5 bags of chips and 5 soda cans cost $8.
How much does a bag of chips cost? How much does a can of soda cost?
Answer:
One bag of chips costs $1.10
One can of soda costs $0.50
Step-by-step explanation:
1. Create a system of equations (b = bags of chips | s = soda)
10b + 8b = 15
5b + 5s = 8
2. Use the Elimination method by multiplying 5b+5s=8 by -2
10b + 8b = 15
-2(5b + 5s = 8)
=
10b + 8b = 15
- 10b - 10s = -16
(10b and -10b will cancel out, so you will only have s left)
=
-2s = -1
Divide by 2
Soda = 1/2, or $0.50
3. Plug in S (0.50) into an equation above and get B by itself
5b + 5(0.50) = 8
=
5b + 2.5 = 8
- 2.5 -2.5
5b = 5.5
Bag of Chips = $1.10
