Mathematics

Answer:

7 (option B)

Step-by-step explanation:

the area of a trapezoid can be found using the formula:

A = \frac{a+b}{2}h

where

A: area

a: base

b: other base

h: height

here, we can plug in our known variables to solve for h (height)

A: 119

a: 10

b: 24

h: ??

A = \frac{a+b}{2}h

119 = \frac{10+24}{2}h

{now, simplify!}

119 = \frac{10+24}{2}h         {add 10 + 24}

119 = \frac{34}{2}h            {divide 34 by 2}

119 = 17 · h

119     =    17 · h

÷ 17       ÷17             {divide both sides by 17to isolate h}

7 = h

So, the height (h) of this trapezoid is 7

hope this helps! have a lovely day :)

How much, in total, did Noel spend to cash her three most recent paychecks?
Stolb23 [73]

Based on the amount that Noel cashed in each of her most recent paychecks, the amount she spent in total is $10.99.

<h3>How much did Noel spend?</h3>

The bank directory shows that you are charged 1.99% of the amount being cashed as well as a check processing fee of $1.39.

The amount Noel spent is therefore:

= (1.99% x 100.53) + (1.99% x 119.38) + (1.99% x 122.52) + (1.39 x 3 checks)

= 2.00 + 2.38 + 2.44 + 4.17

= $10.99

There are exactly three colors of socks in lamont's drawer: red, blue, and green. the current ratio of red to blue to green sock
Harrizon [31]
If the current ratio of red to blue to green socks is 2:3:7, then t<span>here are exactly 2x red socks, 3x blue socks and 7x green socks.
</span>
1. If amount of red socks are increased by n new socks, then t<span>here are exactly 2x+n red socks, 3x blue socks and 7x green socks and (2x+n):3x:7x=8:9:21. This means that 2x+n=8y, 3x=9y, 7x=21y. You have that x=3y and 6y+n=8y, n=2y.
</span>
2. If amount of blue socks are increased by n+2 new socks, then t<span>here are exactly 2x red socks, 3x+n+2 blue socks and 7x green socks and 2x:(3x+n+2):7x=2:4:7. This means that 2x=2t, 3x+n+2=4t, 7x=7t. Now you have that x=t and 3t+n+2=4t, n=t-2.
</span><span>
</span><span>3. Solve x=3y, n=2y, x=t, n=t-2. You obtain that t=3y, t-2=2y. Then 3y-2=2y and y=2. Hence, x=6=t, n=6-2=4.
</span><span>
</span><span>Answer: n=4
