Answer:
4
Step-by-step explanation:
The number on the right squared in equal to the number on the left
5^2 =25
6^2 = 36
What squared = 16
4^2 = 16
The the missing number is 4
Answer:
about 671 miles
Step-by-step explanation:
2014m=3h
2014/3= about 671 miles an hour
3.45 acres
solution :
3.75+3.75= 7.5
7.5-2.9 = 4.6
4.6×.25= 1.15
4.6-1.15= 3.45
Answer:
6/5÷31/10=12/31
Step-by-step explanation:
6/5÷31/10=?Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
6/5×10/31=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
6×10 5×31=60/155
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 60 and 155 using
GCF(60,155) = 5
60÷51 55÷5=12/31
Therefore:
65÷3110=12/31

Area of circle = πr²
--------------------------------------------------
Find radius
--------------------------------------------------
πr² = 75
r² = 75 ÷ π
r² = 23.87
r = √23.87
r = 4.89 cm (nearest hundreds)
--------------------------------------------------
Answer : radius = 4.89cm
