AB is half AC therefore BC is 10 ft

Use Pythagorean theorem.

(8)^2 + (10)^2 = c^2. Square the left side

164 = c^2. Take the square root of both sides

√(164) = c

EC = √(164).

17_2_3_8=3 insert + - × or ÷ symbols to make each statement true​
erastova [34]

Answer:

17-2*3-8=3

Step-by-step explanation:

We have given:

17_2_3_8=3 insert + - × or ÷ symbols to make each statement true​?

<u>Solution:</u>

We will insert multiplication sign between 2 and 3 and then subtract all the terms

<u>17-2*3-8=3</u>

We will solve it according to the DMAS rule:

DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction. Without DMAS rule all mathematical equations will come up with different answers.

Lets solve the expression and check whether the L.H.S = R.H.S

17-2*3-8=3

17-6-8=3

11-8=3

3 =3

<em>Be sure to multiply first and then subtract</em>

⇒You can also insert addition sign in place of multiplication. It will give the same answer

25/9 converted into a mixed number equals
blagie [28]
First figure out how many times 9 can go into 25 **do the highest amount of times it can go in-
<span><span>9x1=9 </span><span>9x2=18 </span><span>9x3=27 </span><span>9x4=<span>36
nine can go in 2 times because 3 times would be way to much
so you're mixed number would be 2
now to figure out you're numerator do 25-18=7
Now it would be 2 7/25
so you're mixed number,then the numerator,finally denomantor ALWAYS stays the same.
                *IF YOU'RE NUMERATOR AND DENOMANTOR CAN BE REDUCED THEN REDUCE</span></span></span>
