ANTONII [103]

Flourish- 120x
Green Thumb- (70x)=1600

Flourish- 120*35= $4200
Green Thumb- (70*35)+1600= $4050

It would be less expensive to hire Green Thumb Landscapers. There is a $150 difference between the two

It would take 32 hours of work for the cost to be the same for both companies<span />

Whitepunk [10]

5x + 8y = -29
7x - 2y = -67 ..... multiply both sides by 4

5x + 8y = -29
28x - 8y = -268

33x + 0y = -297
x = -9

A catalog of scientific equipment states that the lens of a particular telescope has a circumference of 6.28 yards. What is the

nexus9112 [7]

The area of lens is 3.14 square yards.

Step-by-step explanation:

Given,

Circumference of lens = 6.28 yards

Circumference = 2πr

$6.28=2*3.14*r\\6.28=6.28r\\6.28r=6.28$

Dividing both sides by 6.28

$\frac{6.28r}{6.28}=\frac{6.28}{6.28}\\r=1$

Area of lens = πr²

Area of lens = $3.14*(1)^2=3.14*1$

Area of lens = 3.14 square yards

The area of lens is 3.14 square yards.

Keywords: area, circumference
