i think it would be y=3/5
Answer:
Step-by-step explanation:
As you can see the value of y increases uniformly with x, so this is a straight line. A straight line follows the formula of
When x=0, y=5, and therefore c=5
Use the formula of slope to calculate slope
initial volume of balloon =
so intial volume is 113.14 cubic inches
volume after one hour will be 113.14 - 2 = 111.14 inches
new radius
Rate change of radius is
Rate change is 0.7% per hour the radius is decreasing
Answer:
Step-by-step explanation:
x + y = -6
2x - y = 3
3x = - 3
x = -1
-1 + y = -6
y = -5
(-1, -5)
Answer:
She has 20 quarters.
Step-by-step explanation:
Alissa emptied her piggy bank for Disney world. She had $7.70.
If she had 10 pennies and twice as many times as quarters, then we can write the equation as
Q = 2P {Where, Q represents the number of quarters and P for pennies}
⇒ Q = 10 × 2
⇒ Q = 20
So, she has 20 quarters.
Therefore, she has 20 quarters. (Answer)
