Answer:
8 units
Step-by-step explanation:
Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...
A = (1/2)(b1 +b2)h
to find the area.
Here, b1=3, b2=1, h=4, so the area is ...
A = (1/2)(3 +1)(4) = 8
The displacement is 8 units in the time from t=1 to t=4.
$9 is the part, 15% is the percent, and $60 is the whole
$9 is %15 of the whole. This means $9 is the part, 15% is the percent, and the whole is the total cost of the shoes after the discount. The total cost of the shoes after the discount is 60.
Answer:
D) 45 degrees
Step-by-step explanation:
145 = 100 + x
Subtract 100 from both sides
45 = x
OR
180 - 145 = 35
<FEG = 35
100 + 35 + x = 180
135 + x = 180
Subtract 135 from both sides
x = 45
