Umnica [9.8K]

Answer:

62.8yd

Step-by-step explanation:

formula for circumference of a circle = 2 π r

The perimeter is 4 semi circles, so 2 full circles. The diameter is 10yd and the radius is half the diameter, so the radius is 5yd

working:

2 x π x 5 = 31.4yd

31.4 x 2 = 62.8yd

The width of a rectangle is 3x – 3. Its perimeter is 10x + 6. Find the length of the rectangle.

maks197457 [2]

Step-by-step explanation:

The first possibility

2(width) + 2(length) = perimeter

2(3x-3) + 2(length) = 10x+6

6x - 6 + 2(length) = 10x+6

2(length) = 4x + 12

length = 2x + 6

The second possibility.

rondhesha chodado in The width of a rectangle is 3x – 3. Its perimeter is 10x + 6. Find the length of the rectangle.

So you have the perimeter, P, can be found by doing u+u+v+v.

Simplifying gives:

P=2u+2v.

You are given the width is (3x-3). Choose this to be u or v but not both.

Perimeter is given a (10x+6).

Let's plug this in:

(10x+6)=2(3x-3)+2v

We are solving for v.

First step: Distribute where you can:

10x+6=6x-6+2v

Now we want to isolate v.

So we will need to subtract (6v-6) on both sides:

(10x+6)=2v

- (6x -6)

----------------------

4x+12 =2v

The right hand side contains a factor of 2.

The left hand side does too since 4x+12 can be factored as 2(2x+6).

2(2x+6)=2v

This implies v is 2x+6.

Let's check our work.

We have two sides with measurement 2x+6: (2x+6)+(2x+6)=4x+12

We have two sides with measurement 3x-3: (3x-3)+(3x-3)= 6x-6

Let's add those sums to find the perimeter: 10x+6

That is the intended

fabiana decides to save the money she is earning from her after school job for college. she makes an initial contribution of 300

Oxana [17]

Answer:

A. Total Money Contributed after n months = $\$ 3000 + \$ (500\times n)$

B. Total Money Contributed after 24 months = $\$ \ 15000$

Step-by-step explanation:

Given:

Initial contribution = $\$\ 3000$

each month contribution = $\$\ 500$

After 1 month contributed = $\$\ 3000 + \$\ 500 \times 1= \$ \ 3500$

Solving for Part A

let n be the number of months

∴ Total Contribution after n months = Initial contribution + (each month contribution $\times$ Number of months = $\$\ 3000 + \$\ 500 \times n$

Solving for Part A

Now n= 24 months

∴ Total Contribution after 24 months = $\$\ 3000 + \$\ 500 \times 24 = \$\ 3000 + \$\ 12000= \$\ 15000$
