The answer is H because if you use a calculator and do 5.75 - 3.50 you would get 2.25 then count out how many 0.25 would make 2.25

Answer:H

Step-by-step explanation:

Because 0.25 x 9 will give you 2.25. Then add that to the original number; $3.50 + $2.25 = $5.75. Hope this helps :)  

A trapezoid has a height of 10 feet, and base measurements of 20 feet and 8 feet. What is the area?

The answer must be in square feet

Answers

Answer:Therefore, the area of the trapezoid

Step-by-step explanation
To find the area of a trapezoid, you can use the formula: A = 1/2 * (b1 + b2) * h, where b1 is the length of the longer base, b2 is the length of the base, and h is the trapezoid's height.

In this case, the longer base (b1) is 20 feet, the shorter base (b2) is 8 feet, and the height (h) is . We obtain the following result as soon as we insert these values into the formula:
A = 1/2 * (20 + 8) * 10
A = 1/2 * 28 * 10
A = 140 square

Answer:

Step-by-step explanation:

A band expects to put 12 songs on their next CD. The band writes and records 25​% more songs than they expect to put on the CD. During the editing​ process, ​20% of the songs are removed. How many songs will there be on the final​ CD?

Answers

12 songs. 25% of 12 is 3, so you add 3 to 12 and get 15. You then find that 20% of 15 is 3 so you subtract 3 from 15 and get 12 again.
25% of 12 is 3, 12+3= 15. 25% of 15 is 3. 15 - 3 = 12 Answer: 12

Find the slope and the y - interpret of the line in graph

Answers

Answer:

the slope is 2

Step-by-step explanation:

the slope or y intercept is when the line crosses the y axis you can find it by starting at 0 and count how many units until you reach when the line intercepts the y axis.

The slope is 5/1 or just 5. Because it goes up 5 and over one. The Y intercept is 3 because that’s where the point crosses the y axis. Hope this helps!!

Plz help me and explain too thanks

Answers

So start out with -5 then subtract -2 you get -3 then subtract 12-3 and get nine. That’s your answer 9. Hope this helps.
Since the slope is equal to -5 you can already get the beginning of the equation being y=mx+b; M=-5, now to find b you need to plug in your numbers: 12=-5(-2)+b then you get 12=10+b. subtract the 10 to find that b=2 then plug in all the numbers to find the answer y=-5x+2

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?

Answers

Answer:

$460.20

Step-by-step explanation:

499*15% = 74.85 (total discount price)

499-74.85 = 424.15 (deduct discount from original price)

424.15*8.5% = 36.05275 (total tax from price)

424.15+36.05275 = 460.20275 (add tax to discounted price)

the answer is $460.20

Answers

Answer: 82°

Step-by-step explanation:

6 = 98°

180° - 98° = 82°

The measure of angle 7 is 82°.

What is the vertical angles' theorem?

According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.

Given:

In the diagram, the measure of angle 6 is 98°.

A transversal intersects 2 lines to form 8 angles.

Clockwise from the top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8.

Angle 6 and Angle 7 are supplementary angles.

So,

m∠7 = 180 - 98

m∠7 = 82°

Therefore, m∠7 = 82°.
