Answer:
6.5 m^2
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying height to the base
If the area is 78 m^2 and base is 12 we can find the height by dividing the area by base
78 ÷ 12 = 6.5 m^2
Answer:
The radius of the circle is 160cm
Step-by-step explanation:
circumference of circle = 2πr
circumference = 320π cm
2πr = 320π
2r = 320
r = 160 cm
Using proportions, the multiplication expression to determine the total change in the value of these cars at the dealership is given by:
T = -1,200 x 42.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, we have that one car depreciated on average -$1,200. We want to find the amount relative to 42 cars, and this amount can be found by the following<em> rule of three</em>.
1 car - -$1,200.
42 cars - $T
Applying cross multiplication, the expression is given by:
T = -1,200 x 42.
