The blue ball is more than the red ball because there isn't anything smaller than kilograms
Answer:
Heather's model has greater area by 24 sq.ft.
Step-by-step explanation:
Given : Ellie's model represented 20 feet by 15 feet.
Heather's model represented 18 feet by 18 feet.
To Find: Whose floor model represents the greater area? How much greater?
Solution:
Length of Ellie's model = 20 feet
Width of Ellie's model = 15 feet
Area =
=
=
Length of Heather's model = 18 feet
Width of Heather's model = 18 feet
Area =
=
=
Thus Heather's model has greater area by (324-300)= 24 sq.ft.
Answer:
5 - 2x
Step-by-step explanation:
Translating words to numbers can be tricky.
Here it says: "5 decreased by twice a number." So you have to imagine-- I started with Five things. Then there was a decrease --twice some variable.
5 take away twice something translates to
5 - 2x
Tricky, because most algebra expressions are written with variables first, then the constants. You could rewrite this expression as
-2x + 5
The amount of blue paint in each container is .
Further explanation:
The mixture mixed by Mrs. Cleaver contains 1.24 litres of red paint with 3 times blue paint to obtain purple paint.
So, the amount of blue paint is calculated as,
Therefore, the total amount of paint mixture is the sum of blue paint and red paint.
Now, as Mrs. Cleaver divides the paint mixture equally in 5 containers so the amount of paint in one container is calculated as,
Since amount of blue paint mixed is three times the red paint so the fraction of blue paint to the total paint is .
Now, as it is known that the fraction of blue paint to the total paint is and the amount of paint in a container is then the blue paint in one container is calculated as,
Thus, the amount of blue paint in each of the five containers is .
