Answer:
$3.25 per gallon
Step-by-step explanation:
She had $30 and now has $4, so she spent $30- $4 = $26
With $24 she bought 8 gallons of gas.
$26/(8 gallons) = $3.25/(1 gallon) [ divide 26 by 8 to get the unit rate]
She spent $3.25 per gallon
Answer:
a.
b.
Step-by-step explanation:
To solve this question, we apply implicit differentiation.
xy = 2
Applying the implicit differentiation:
a. Find dy/dt, when x = 4, given that dx/dt = 13.
x = 4
So
Then
b. Find dx/dt, when x = 1, given that dy/dt = -9.
x = 1
So
Then
Answer:
2369.86
Step-by-step explanation:
f(36)=3700(1−0.06) ^36/5
2369.857704098921
Answer:
Step-by-step explanation:
2x + 9 = 15
you move + 9 to the other side of the equation, you will get:
2x = 15 - 9
2x = 6
So, x = 3
The value of x is
180=32+2x+16+x-24
180=24+3x
156 =3x
52
So Cbe angle=56-24
= 32
