Answer:
x=12
Step-by-step explanation:
The right side is a right triangle
The base is 1/2 of the bottom or 5
The height is x and the hypotenuse is 13
We can use the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +x^2=13^2
25+x^2 = 169
Subtract 25 from each side
25-25+x^2 = 169-26
x^2 =144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x= 12
Answer:
3,71
Step-by-step explanation:
4,01 - 1,08 ÷ 3,6
4,01 - 0,3
3,71

Answer:
Fraction=3/10
Decimal=0.3
Percent=30%
Step-by-step explanation:
First we have to add 12+16 so we can find how many marbles are left
12+16=38
Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles
40-38=12
There are 12 blue marbles.
Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.
Probability=
12/40
Simplify
12/40
6/20
3/10
Probability
Fraction=3/10
Decimal=0.3
Percent=30%
4, because the highest power is 4
