Triangle DEF is a right triangle. If FE=5 and DF=13, find DE.
Nadya [2.5K]

Answer:

13

Step-by-step explanation:

I am amusing you are looking for the hypotenuse since this is middle school.

If you have the legs and are looking for the hypotenuse you use the Pythagorean Theorem a^{2} + b^{2} = c^{2}

The legs are a and b, and the hypotenuse is c

The work would look like this

13^{2} + 5^{2} = c^{2} \\169+25= c^{2} \\194= c^{2} \\\sqrt{194} = \sqrt{c^{2} } \\13.9283883... = c

extra notes

  • I rounded to 13
  • If you didn;t know you cancles exponents with roots

so the c^{2} is cancled by aka \sqrt{c}

Hope this helped :)

Which estimation could be used to make sure the answer is reasonable?
Naddika [18.5K]

Let's go through each answer.

A.

Answer: The amount left over was 4.05 L.

Estimation: 3.15 + 4.75 is about 7.

7 L – 4 L = 3 L

The amount left over was about 3 L.

This is incorrect because 3.15+4.75 is closer to 8 than 7.

B.

Answer: The amount left over was 3.95 L.

Estimation: 3.15 + 4.75 is about 8.

8 L – 4 L = 4 L

The amount left over was a little less than 4 L.

This is correct because 3.15+4.75 is close to 8 and to find the amount left over you do have to subtract.

The correct answer is B.

Answer: The amount left over was 3.95 L.

Estimation: 3.15 + 4.75 is about 8.

8 L – 4 L = 4 L

The amount left over was a little less than 4 L.

Hope this helps!. If it helped, please rate, thank, and if it really helped, give brainliest. It helps me rank up. Thanks! :)

PLZZZHELP <br> ill mark brainliest
ludmilkaskok [199]

Answer:

y=\frac{x+2}{4} or y = 0.25x + 0.5

Step-by-step explanation:

You need to try change the subject from x to y.

x = 4y - 2

We first move -2 to the left, making the equation

x + 2 = 4y i.e.

4y = x + 2

We then divide both sides by 4.

y=\frac{x+2}{4} or y = 0.25x + 0.5

We now have successfully made y the subject, and effectively solving the equation.
