Answer:

200 cm^{2}

Step-by-step explanation:

SA = LA + 2B     where LA is the lateral area and B is the area of the base(triangle)

LA = ph     p = perimeter of base and h = distance between bases

LA = (5 + 5 + 6)11 = 176

B = bh/2 = 6(4)/2 = 12

SA = 176 + 2(12) = 176 + 24 = 200 cm^{2}

Answer:

<u>SA = 189 cm^2</u>

Step-by-step explanation:

What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!

Starting with triangles: area = 1/2 * l * h

So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2

Since we have two triangular sides, that totals to 24 cm^2.

Then the rectangular sides: area = l*h

so, 5*11 = 55 cm^2

We have three rectangular sides, totalling 165 cm^2

165+24 = 189 cm^2

8. Colby and Cheryl work in different local supermarkets. Colby regularly earns $8.90 per hour,
faust18 [17]

Answer:

colby

hourly rate =$8.90

overtime rate = time and a half = 1.5

the hourly overtime rate is the product of the overtime rate and the hourly rate.

hourly overtime rate= overtime rate × hourly rate

= 1.5 × $8.90

= $13.35

Cheryl

hourly rate = $7.10

overtime rate = double time = 2

the hourly overtime rate is the product of overtime rate and the hourly rate.

hourly overtime rate = overtime rate × hourly rate

= 2 × $7.10

= $14.20

<h3>Comparison</h3>

we note that the hourly overtime rate of cheryl is higher than the hourly overtime rate of colby, which implies that cheryl earns more for one hour of overtime.

we are also interested in the difference of the hourly overtime rate:

hourly overtime rate colby — hourly overtime rate cheryl

= $14.20 – $13.35

= $0.85

thus cheryl earns $0.85 more for one hour of overtime than colby .

<h3>result</h3>

<h2>cheryl,$0.85</h2>

First you would subtract the monthly fee from the total bill
14.30 - 1.95 = 12.35
Maria spend $12.35 on songs, to find out how many songs, you divide that by $.95
12.35 \div .95 = 13
