Use Pythagorean theorem:

Leg^2 + leg^2 = hypotenuse^2
15^2 + leg^2 = 25^2
225 + leg^2 = 625
Leg^2 = 400
Leg = 20 :)

The product of eight and a number decreased by four is the same as eight plus five time the same number.
dedylja [7]

Answer:

The Answer is: The Number is 4

Step-by-step explanation:

Let n = the number.

Eight times a number minus 4 equals 8 plus 5 times the number.

8n - 4 = 8 + 5n

3n = 12

n = 4, the number is 4.

Proof:

8(4) - 4 = 8 + 5(4)

32 - 4 = 8 + 20

28 = 28

Hope this helps! Have an Awesome Day!! :-)

How can you use a quick picture to find 3x2.7
NeTakaya
If you mean like a method to solve it fast here I have 1 solution I usually use;

3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.

Someone please help me with this
Sauron [17]

Answer:

  not similar; corresponding sides are not proportional

Step-by-step explanation:

If the triangles were similar, corresponding sides would be proportional. That is, you would have ...

  AX/AB = AY/AC

Here, those ratios are ...

  6/24 ≠ 10/35

so, the corresponding sides are not proportional, and the triangles are not similar.

You want to make five-letter codes that use the letters A KE R. and Mwithout repeating any letter. What is the probability that
Crank

Answer:

0.05

Step-by-step explanation:

There are five letters to choose from. Since there is no repetition, you can choose one of 5 for the first letter, one of four for the second letter, etc. The total number of five-letter codes is

5 * 4 * 3 * 2 * 1 = 120

Now we need to find out the number of codes that start with M and end with E.

The first position is occupied by M. There is one single letter that can be placed there. The last position is occupied by E. There is a single letter that goes there. There are 3 letters left.

1 * 3 * 2 * 1 * 1 = 6

There are 6 codes that start with M and end with E

p(code that starts with M and ends with E) = 6/120 = 0.05
