Komok [63]

Answer:

0.0325

Step-by-step explanation:

Only 6. Please and thanks
salantis [7]

Answer:

Part a) 7.536\ m

Part b) \$34.14

Step-by-step explanation:

Part 6)

a) How much edging is needed?

we know that

To find out how much edging is needed determine the circumference of the circular garden

The circumference of the circular garden is equal to

C=\pi D

where

D is the diameter

we have

D=2.4\ m

assume

\pi =3.14

substitute

C=(3.14)(2.4)

C=7.536\ m

Part b) we know that

To find out the cost to edge the garden, multiply the length of edging plastic needed by the cost of $4.53 per meter

so

(7.536\ m)(4.53\ \$/m)=\$34.14

<h3>What is a number line?</h3>

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

Given a solid dot at 3, while an open dot at -1, also, there is a line from -1 to 3. Therefore, the integer values that satisfy the given diagram are 0, 1, 2, and, 3.
