Answer:
b= X*69=Y
Step-by-step explanation: If you buy 10 apples, and each apple costs 69 cents how much will it cost? 10*69=Y, now replace 10 with x, and you will have the answer.
The top surface area of the wedge with central angle of π / 2 radian is 9π / 4 inches square
<h3>How to find area of a sector?</h3>
The area of the top surface of the the wedge is the area of a sector.
Therefore,
area of the top surface = ∅r² / 2
area of the top surface = π / 2 × 3² × 1 / 2
area of the top surface = π / 2 × 9 × 1 / 2
area of the top surface = 9π / 4
area of the top surface = 9π / 4
area of the top surface = 9π / 4 inches squared

A = 2(6)(8)/2 + 8(7) + 7(10) + 6(7)
A = 146 sq m
Therefore the surface area of the triangular prism is 146 m^2.
Twelve a? Do you mean 12a? Because 12a just equals 12a, there is no way else to simplify it.
Answer:
<em>The field is 1 and 4/10 mile long.</em>
Step-by-step explanation:
If I understand the question:
(1/2) + (9/10) =
(5/10) + (9/10) = (14/10)
(14/10) is 1 and 4/10
The field is 1 and 4/10 mile long.
