She spent 17 hours tutoring
$210 = 7 hours
$20 x 10 hours = $200
$210 + $200 = $410
7 Hours + 10 Hours = 17 Hours
Check the picture below, you can pretty much count the units off the grid for the length and width.
recall area = length * width.
Answer:
h = 3.6
Step-by-step explanation:
This is just substituting in for variables and solving for x. The hard part is knowing the formula.
R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.
Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.
(8.1) = h(((1) + (3.5)) / 2)
= h((4.5) / 2)
= h(2.25)
8.1/2.25 = h
3.6 = h
Answer:
2a + b/4
Step-by-step explanation:
The expression is the sum of two terms (2a + b/4)
The first term is the <u>product (</u>Multiply<u>)</u> of 2 and a (2a)
The second term is the <u>quotient</u> (Divide) of b and 4 (b/4)
