Let K = km in 7 weeks
Equation:
K = 7(20)
Answer:
583$
Step-by-step explanation:
6% is equal to 0.06, so you multiply 550 by 0.06. which equals 33. Then, because it asks for how much Katie played, including the tax and TV, you add 33 to 550.
Answer:
x = (5/6 , 0) y = (0 , 5/3)
Step-by-step explanation:
for x you plug in a zero for y so it looks like this
6x-3(0)=5
6x=5
x=5/6
then for y you plug in 0 for x
6(0)-3y=5
-3y=5
y=-5/3
Answer:
14 hours and 42 minutes
Step-by-step explanation:
- 12 hours later is 7:18pm
- 2 hours later is 9:18pm
- 60-18=42 minutes
- 12 hours + 2 hours plus 42 minutes = 14 hours and 42 minutes
Answer:
DA/dt = 37 / 18
Step-by-step explanation:
We have the following information:
Sides of the rectangle L = length w = width
Area of the rectangle is : A = L* w
the rate of growing of the length ( as function of time ) 1 mile in 6 years
we can express that as :
DL/dt = 1 /6
And the rate of growing of the width ( as function of time ) 1 mile in 9 years
Dw/dt = 1/9
In 1995 dimensions of the rectangle were
L = 5 miles and w = 9 miles
Then:
A = L * w Taking derivatives
DA/dt = L * Dw/dt + w * DL/dt
DA/dt = 5 * (1/9) + 9 * (1/6) ⇒ DA/dt = 5/9 + 9/6
DA/dt = 111 / 54 ⇒ DA/dt = 37 / 18
