Answer:

42.25 m^2

Step-by-step explanation:

The area of a trapezoid = (h/2)(a + b) where h = altitude, and a and b are the 2 parallel sides.

So the area of this one = (6.5 / 2) ( 8.5 + 4.5)

=  42.25 m^2

Sue buys 5 pieces of fabric.Each piece is 1 7/10 yards long.What is the total length of the fabric she buys?One yard of the fabr
Bumek [7]

Answer:

1. 8.5 yards.

2. $42.5

Step-by-step explanation:  

We have been given that Sue buys 5 pieces of fabric. Each piece is 1\frac{7}{10} yards long.

1. To find the total length of fabric bought by Sue we will multiply length of each fabric piece by 5.

\text{Total length of the fabric}=5\times 1\frac{7}{10}\text{ yards}

\text{Total length of the fabric}=5\times \frac{17}{10}\text{ yards}

\text{Total length of the fabric}=\frac{17}{2}\text{ yards}

\text{Total length of the fabric}=8.5\text{ yards}

Therefore, Sue bought 8.5 yards of fabric.

2. 1 yard of fabric costs $5.

So 8.5 yards of fabric will cost : 5*8.5

\text{Total cost of the fabric}=5\times 8.5

\text{Total cost of the fabric}=42.5

Therefore, the cost of total fabric bought by Sue is $42.5.

Under his cell phone plan, Ian pays a flat cost of $59.50 per month and $5 per gigabyte. He wants to keep his bill under $80 per
inessss [21]
You would start by saying his budget is $80 so you start with 80= he pays an initial fee of $59.50 every month plus $5 per gigabyte so you would set it up like
80=59.50+5x
X being how many gigabytes he uses then you solve 80-59.50 is 20.5 divided by 5 gives you 4.1 but you round down cause you don’t want to pass the limit so therefor the most gigabytes he can use is 4
