Given :
Peter velocity , P = 30 mph .
Mitchell velocity , M = 40 mph .
Mitchell leaves 15 min later .
To Find :
If they drive along the same route how long will it take Mitchell to catch Peter.
Solution :
Distance covered by Peter in 15 min .
[tex]D = 30\times \dfrac{15}{60}=7.5\ miles[/tex]
Let , time taken is x .
So , distance covered b them is equal :
[tex]7.5+30\times x=40\times x\\\\x=\dfrac{7.5}{10}=0.75\ hours\\\\x=0.75\times 60\ min\\\\x=45\ min[/tex]
Therefore , time taken by them is 45 minutes .
Hence , this is the required solution .

The price of a video game was reduced from $60 to $45. By what percentage was the price of
the video game reduced?
Answer: It was reduced by 25%
Step-by-step explanation: to go from $60 to $45, you would've gone down $15. 15, or $15, if 1/4 of 60, or $60. 1/4 also is 25%, so the price would have gone down by 25%.
-4k + 2(5k − 6) = −3k – 48
Answer:
k = -4
Step-by-step explanation:
-4k + 2(5k − 6) = −3k – 48
Distribute on the left side.
-4k + 10k - 12 = -3k - 48
Combine like terms on the left side.
6k - 12 = -3k - 48
Add 3k to both sides.
9k - 12 = -48
Add 12 to both sides.
9k = -36
Divide both sides by 9.
k = -4

Answer:
2760 ft^3
Step-by-step explanation:
volume of a cube formula:Length * width* height
volume of the big cube= 11*10*22
= 2420 ft^3
volume of the small cube=7*4*10
=280 ft^3
now to find the total volume= volume of the big cube + volume of the small cube
=2420 + 280
=2760 ft^3
Help ASAP please and explain why ?!
Answer:
It is C, because to find volume you must use the formula l×w×h, or length times the width times the height. (cm^3)
Answer:
C
Step-by-step explanation:
Unlike area that's cm² because it's like A= L*W
Volume is cm³ because it's like A= L*W*H

The local coffee house reported losses of -⅜ of their normal profit each day for 3 days. If their normal profit is $350 a day how much money was lost for the 3 days?
Answer:
Total loss in three days = $393.75
Step-by-step explanation:
Given:
Loss amount = [-3/8] of normal profit
Normal profit per day = $350
Find:
Total loss in three days
Computation:
Total loss in three days = 3 [Normal profit per day][Loss amount]
Total loss in three days = 3 [350][3/8]
Total loss in three days = 3[131.25]
Total loss in three days = $393.75

Please help Factor the expression using the GCF the expression 32z-48 factored using the GCF is
Answer:
16(2z -3)
Step-by-step explanation:
There are two ways of solving this problem.
List out the factors of the numbers:
32z - 48
= 32 * z - 48
32= 1, 2, 4, 8, 16, 32
48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
the largest common factor that both numbers have in common is 16,
So factoring the equations means the one has to divide the equation by 16 and write it outside of the parenthesis.
16 * ( 2 * z - 3)
16(2z -3)
Another way of solving the problem:
prime factorize the number:
32 = 2^5
48 = 2^4 * 3
Both numbers have 2^4 as their largest factor in common meaning that that is their GCF. 2^4 is 16.
Now factor out 16 and write it on the outside of the parenthesis.
16 * ( 2 * z - 3)
16(2z -3)
Answer:
16(2z -3)

How do I find the domain and range of a graph?
The domain is the x-axis and the range is the y-axis.
To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.
To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.
Final Answer
D: -3 ≤ x ≤ 3
R: -4 ≤ x ≤4
