Given the area of a trapezoid is 86 in’, and the height is 4 in. If one base is 18 in, determine the other base.
Rus_ich [418]

Answer:

25 = base

Step-by-step explanation:

I searched all of this on YT to try and help

so first we need to know the area of a Trapezoid

A = 1/2h(b + b)

86 = 1/2(18 + b)4

we dont know the base where going to put b

we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.

172 = (18 + b)4

the 4 is multipling so divide it on both ends.

43 = (18 + b)

then do the opposite operation on the 18, by subtracting 18 on both sides.

25 = b

is the base

check the work by plugging it back in

A = 1/2h(b + b)

A = 1/2 4(18+25)

A = 1/2 4(43)

A = 1/2(172)

A = 86in

Nina worked 32 hours this week. She earned a total of 360. How much does she make per hour? Write and solve equation.
NeX [460]

Nina makes 11.25 per hour.

Step-by-step explanation:

Given,

Number of hours worked by Nina = 32 hours

Amount earned by Nina = 360

Let,

x represent the amount earned by Nina per hour.

Amount per hour * Number of hours = Amount earned

32*x=360\\32x=360

Dividing both sides by 32

\frac{32x}{32}=\frac{360}{32}\\x=11.25

Nina makes 11.25 per hour.

Please help explain!!!!
Inessa [10]

Answer:

x=81 degrees z=99 degrees y=68 degrees

Step-by-step explanation:

first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180)  so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees
