Answer:
1725 ft²
Step-by-step explanation:
The formula for the area of a trapezoid is ...
A = 1/2(b1 +b2)h
Here, the bases are given as 65 ft and 50 ft, and the height is 30 ft. Then the area is ...
A = 1/2(65 ft +50 ft)(30 ft) = (1/2)(115 ft)(30 ft) = 1725 ft²
You tell the salesman your lawn area is 1725 square feet.
Answer:
-0.47
Step-by-step explanation:
s = # of songs
y = total amount of money
$11 + $1(35) = y
Simplify the right side
$11 + $35 = y
Combine like terms
$46 = y
If he downloaded 35 songs, he would have ti pay $46
If he downloaded s amount of songs, he would have to pay $11 + $1s = y
Let's do subtraction by first starting with the ones place and then the tenths place of the subtrahend.
45-4=41; 44, 43, 42, 41
41-.5= 40.5; 40.9, 40.8, 40.7, 40.6, 40.5
45-4.5=40.5
We can check by using addition.
40.5+4.5=
44+1=
45
