So far Andrea and her partner have completed 75% of the 12-page essay, that means they still have to complete 25%.

What you have to do is find 25% of 12

The first thing you should do is turn 25% into a decimal and then multiply it by 12 and the final answer should equal the number of pages that Andrea and her partner have left to write.

So, 0.25*12=3       Therefore they have 3 pages left to write.

So if they wrote 25% of the 12 total pages in class that would leave 9 pages left to do.
25% of 12 = 9

Then if they wrote 50% of the remaining 9 pages that would give you 4.5
50% of 9 = 4.5

So then we would add up the two totals to get 7.5
4.5 + 3 = 7.5

Lastly, we would subtract 7.5 from 12 to get our remaining number of pages left to be written
12-7.5=4.5

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

2x-10+2x-10+3x+25=180       <em>combine like terms</em>

(2x+2x+3x)+(-10-10+25)=180

7x+5=180           <em>subtract 5 from both sides</em>

7x=175              <em>divide both sides by 7</em>

x=25

m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o

<h3>Answer: D. m∠C = 40</h3>

The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to
Maksim231197 [3]

Considering the given function, we have that:

a) D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.

b) D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.

<h3>What is the function in this problem?</h3>

The distance that the family is from home, after t hours of driving, is given by:

D(t) = 3260 - 55t.

Then, after 12 hours, the distance is given by D(12), that is:

D(12) = 3260 - 55 x 12 = 2600.

D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.

D(t)=2490, hence:

3260 - 55t = 2490

55t = 770

t = 770/55

t = 14

D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.
