Answer:
13 seconds
Step-by-step explanation:
Since distance is directly proportional to time,
distance = time * a constant
Lets make A the constant
So, 54 = 9A
A = 6
Now, since distance = 78,
78 = time * A
From above, we can see that A = 6, so
78 = time *6
time = 13
Answer:
C. y=11x
Step-by-step explanation:
y = total amount of money earned
x = hours he works
y = 11x
He earns $11 per hour, so multiplying 11 by x, the number of hours, you are able to find the total amount of money he earns, y.

Step-by-step explanation:

Use a^2 + b^2 = c^2
Then find the volume.
Step One
a^2 + b^2 = c^2
c = 10
b = 6
Find a
a^2 + b^2 = c^2
a^2 + 6^2 = 10^2
a^2 + 36 = 100
a^2 = 100 - 36
a^2 = 64
a = sqrt(64)
a = 8
Step Two
Find the volume
a = 8
b = 6
h = 12
V = 1/2 * a * b * h
V = 1/2 * 8 * 6 * 12
V = 288 m^3 <<<<<<< answer
Same and same. They're congruent which means they have the same size and the same shape.
