Answer:
27
Step-by-step explanation:
Let g be Gabrielle's age and m be Mikhail's age.
We can turn the statements the problem gives us into mathematical expressions to help us solve.
Gabrielle's age is two times Mikhail's age:
g = 2m
The sum of their ages is 81:
g + m = 81
This gives us a system of equations that will allow us to solve for Gabrielle's age.
g + m = 81
(2m) + m = 81
3m = 81
m = [tex]\frac{81}{3}[/tex]
m = 27
If we need to solve for Gabrielle's age, we can do the following.
g = 2m
2(27) = g
54 = g
g = 54
Mikhail's age is 27.
Gabrielle's age is 54.
Answer:
Mikhail is 27
Step-by-step explanation:
Use 'm' to represent Mikhail's ageUse g = 2m to represent Gabrielle's age (because Gabrielle's age is twice that of Mikhail's.You know that both of their ages combined must equal 81. This can be represented by g + m = 81Lastly, since we stated g=2m, substitute it into the equation to make: 2m + m = 81Combine like variables and divide to get Mikhail's age.**If you want to find Gabrielle's age, multiply Mikhail's age by two, as represented by the equation g=2m. Gabrielle is 57.

The volume of a cylinder is 81 pi in^3 and the height of the cylinder is 1 in. What is the radius of the cylinder
Answer:
18/20π
Step-by-step explanation:
81π ÷ 1 = 81π
81π ÷2 = 18/20π
You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.
simplify the following 72÷6+3×2
Answer:
18
Step-by-step explanation:
Use PEDMAS
In this, we have to do first division , then multiplication and finally addtion.
72 ÷ 6 + 3*2 = 12 + 3*2 {division is done}
= 12 + 6 {Multiplication is done}
= 18

Answer:
m<B = 141 degrees
Step-by-step explanation:
This shape is a heptagon meaning its angles should have a sum of 900 degrees.
we are given the degrees and we need to ad them up
148+90+120+129+130+142=749
then we subtract 749 from 900 which looks like
900-749=141
from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees
-7/3y-2/9=1/3 solve for y
Answer:
y = -12
Step-by-step explanation:
-7/3y - 2/9 = 1/3
cross multiple for 1/3:
-21/3y - 6/9 = 1
cross multiply for 3y and 9:
-21 - 6 = 3y + 9
3y + 9 = -27
3y = -36
y = -12

b. It is
that the spinner will land on orange.
The probability that the spinner will land on orange is the likelihhood of landing on orange
The probability that the spinner will land on orange is 0.75
How to determine the probability?From the question, we have:
Spinner section = 16
Orange section = 12
So, the probability that the spinner will land on orange is:
p = 12/16
Evaluate
p = 0.75
Hence, the probability that the spinner will land on orange is 0.75

A triangle has an area of 54 m² and a height of 9 m.
How long is the base of the triangle?
Enter your answer in the box.
Answer:
base = 3
Step-by-step explanation:
The area of triangle is calculated using the following formula:
1/2*b*h (b: base, h: height)
The area and height is given, to find the base we can make the following equation:
1/2*b*9 = 54
9b/2 = 54 multiply both sides by 2
9b = 27 divide both sides by 9
b = 3
