Answer:7,200 mph
Step-by-step explanation:
36,000 divided by 5
2 blocks = 1 minute
18 blocks = 9 minutes
60 blocks = 30 minutes
She already ran for 9 minutes. She needs to run 42 more blocks.
If we subtract 9 minutes from 30 minutes, we get 21 minutes. Therefore, she needs to run 21 more minutes.
To verify this, we check the proportionality.
2 blocks = 1 minute
42 blocks = 21 minutes
42 blocks / 21 minutes = 2 blocks per minute
Hope this helps!
This is a proportion problem. Set up your equation:
8/96 = 7/x
Now cross multiply
96 x 7 = 672
672/8 = 84
Answer is $84
Answer:
<h2> $287.50</h2>
Step-by-step explanation:
From the problem statement the cost price per box is
$250.
And the box contains 4 specific powers, since Zeus plans to make $900 per box which contains 4 powers
we need to find the selling price
profit= selling price-cost price
let the selling price be x
900=x- 250
x=900+250
x= 1150
Selling price = $1150
<em>Hence the unit cost of a specific power in a box that will see a profit of $900 per box is 1150/4= $287.50</em>
Answer: A B
Group 1 0.25 0.75
Group 2 0.44 0.56
Step-by-step explanation:
Since we have given that
Number of people of A in group 1 = 15
Number of people of B in group 1 = 45
Total number of people in group 1 is given by
Relative frequency of people of A in Group 1 is given by
Relative frequency of people of B in Group 1 is given by
Similarly, Number of people of A in group 2 = 20
Number of people of B in group 2 = 25
Total number of people in group 2 is given by
Relative frequency of people of A in Group 2 is given by
Relative frequency of people of B in Group 2 is given by
Hence, A B
Group 1 0.25 0.75
Group 2 0.44 0.56
