The following diagram shows that the state of Nevada is shaped somewhat like a trapezoid. Which measurement is the approximate a
Vedmedyk [2.9K]

Answer:

110,400\ mi^2

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The area of a trapezoid is equal to

A=\frac{1}{2}[b_1+b_2]h

where

b_1 and b_2 are the length of the parallel bases

h is the height (perpendicular distance between the parallel bases)

we have

b_1=210\ mi\\b_2=480\ mi\\h=320\ mi

substitute

A=\frac{1}{2}[210+480]320=110,400\ mi^2

Last year a married couple had their first two children- twins should they file their federal income tax return using the 1040EZ
Advocard [28]

Last year, a married couple had two children

It means that they need to claim dependents, while filing their taxes.

Form 1040EZ doesn't allow to claim any dependents. Hence, the couple will need to use Form 1040 . It is a longer form, but this is what will be required to do since they have children now.

Pls help it due tomorrow​
Sergio039 [100]

Answer:

Finding 1/5 of something is the same as dividing that number by 5. Since 24 isn't divisible by 5, 24 / 5 is not an integer. Since you can't have 4.8 species of animals the answer to (a) is no.

For (b), 1/3 * 24 = 8 and 24 - 8 = 16.
