In a right triangle, if the length of the hypotenuse is 52 and the length of one of the other sides is 20, what is the length of the third side ?

Answers

Answer 1

Answer:

$\text{Hello there!}\n\n\text{We would use the Pythagorean theorem to find the length of the unknown side}\n\n\text{Pythagorean theorem:}\n\na^2+b^2=c^2\n\n\text{a = 20; c = 52}\n\text{c is the hypotenus and a is one of the side length}\n\n20^2+b^2=52^2\n\n\text{Solve:}\n\n20^2+b^2=52^2\n\n400+b^2=2704\n\nb^2=2304\n\n√(b)=√(2304)\n\n\large\boxed{b=48}$

An office supply store sells report covers at 3 for $0.96. If the rate remains the same, how much will 10 covers cost? Please show your work. Explain.

Answers

We can use a proportion to figure this out.If we get 3 for 0.96 (3/0.96) how many can we get for 10 (10/x)?So far it should look like this 3/0.96= 10/xNow we cross multiply. 0.96 times 10 is 9.6 and 3 times x is 3x. To get rid of the 3 we divide by it to get x alone. So 9.6 divided by 3 equals 3.2. I hope that this helps you. Try writing out the proportion of you don't understand! :)

First, let's find the area of the patio:

6.25 * 6.25 = 39.0625

Next, we need to find the area of the patio and extension combined:

We know that the patio is now 3m wider and 1.5m longer.

(6.25 + 3) * (6.25 + 1.5)

9.25 * 7.75 = 71.6825

Then, we need to find the area of the extension alone, which can be done by subtracting the area of the patio from the area of the patio and extension combined:

71.6825 - 39.0625 = 32.625

Now, find the area of one tile:

0.25 * 0.25 = 0.0625

And divide the area of the extension by the area of one tile to find the number of tiles needed to build the extension:

32.625 / 0.0625 = 522

Divide the total number of tiles by 25 and round up to the nearest whole number to find the number of packages:

522 / 25 = 20.88

20.88 rounds up to 21 packages of tiles.

Ellis needs 21 packages of tiles.

Hope this helps!! :)

Answer:

Step-by-step explanation:

Area to be covered:

(6.25 + 1.5)(6.25 + 2(1.5)) - 6.25²

= 32.625

Each title's area = 0.25² = 0.0625

No. of tiles needed:

32.625 ÷ 0.0625

= 522

25 in each pack

522/25 = 20.88

So 21 packets

Jason owes $15 for last months gas bill also. The total amount of two gas bills and split evenly among the four roommates.

Answers

Answer:

The gas bill of two months splitted among four roommates evenly is:

$7.25

Step-by-step explanation:

Jason owes $15 for last months gas bill also.

Also gas bill of this month=$14

Total gas bill for two months= $(14+15)

= $29

Divide this into four people=$(29/4)

= $7.25

Hence, The gas bill of two months splitted among four roommates evenly is:

$7.25

Answer:
$15+$14=29
When you divide among four roommates
$29/4=$7.25

You are asked to draw a triangle using three of the following angles: 0°, 30°, 45°, 55°, 60°, 80°, 90°, 105°. Which triangle cannot exist?A) 30°, 60°, 90°
B) 45°, 55°, 80°
C) 30°, 45°, 105°
D) 30°, 45°, 55°

Answers

Answer:

Step-by-step explanation:

When you add all the the angles of a triangle, they will end up to be exactly 180 degree. When you add the three numbers A, B, and C end up with 180 degree, but D end up with 130 degree, therefore, D is the triangle that cannot exist.

Hope it helps :D
