96%
hope this helps!!:)
Step-by-step explanation:
Answer:
I think the question is supposed to be What is 25% of 24? Or you are missing a component of the question
Step-by-step explanation:
You could multiply .25 times 24 to get the answer because changing 25% to a number you can use in an equation means adding a decimal place and moving two places to the left.
.25 x 24= 6
6 is 25% of 24
Martin ordered a pizza with a 12-inch diameter. Ricky ordered a pizza with a 16-inch diameter. What is the approximate difference in area of the two pizzas in
square inches?
OA. 4
OB. 16
O C. 112
O D. 352
Answers
Answer:
88 in²
Step-by-step explanation:
The shape of a pizza = Circular
Area of a circle = πr²
For Martin
Martin ordered a pizza with a 12-inch diameter.
Radius = Diameter/2 = 12 inch/2 = 6 inch
Area of Martin's pizza = π × 6²
= 113.09733553 in²
≈ 113.1 in²
For Ricky
Ricky ordered a pizza with a 16-inch diameter.
Radius = Diameter/2 = 16 inch/2 = 8 inch
Area of Martin's pizza = π × 8²
= 201.06192983in²
= 201.1in²
The approximate difference in area of the two pizzas in square inches is calculated as:
201.1 in² - 113.1 in²
= 88 in²

Micah has 15 games. Micah has three more games than kelly. Kelly has K number of games. Move values into the boxes to create an equation to represent this senerio
Answers
Answer:
Equation = K + 3 = 15
K = 12 games
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Micah games = 15
Let, Kelly games = K
As Micah has three more games than Kelly, then
K + 3 = 15
This equation shows the scenario.
We can find the number of games Kelly has by using this equation,
K+3 = 15
K = 15 - 3
K = 12
Hence, Kelly has 12 games.

Ebony is x years old.
Her brother is 4 years older.
Her Mum is 3 times her age.
Write an expression for the age of:
Her mum
Her brother
Answers
Ebony's brother is x + 4 years old.
Ebony's mum is 3x years old.
Explanation:Since Ebony is x years old, and her brother is 4 years older than her, the expression is x + 4, as her brother is +4 years older.
Ebony's mum is 3 times Ebony's age, which is x. 3 times x is shortened into 3x.
