Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
Question 1: 6 3/4 so option b
Answer:
24
Step-by-step explanation:
<u>First, we round the fractions. </u>
If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.
7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.
1/8 is less than half so we round down and remove the fraction so we are left with 10.
<u>Then we add.</u>
14+10=24
