Answer:
The correct answer is 9.
Step-by-step explanation:
Let's start by analyzing the information we have.
We know that Takala put 9 marbles in the box, jackie put in 7, and laird put in 11.
Before continuing, the most convenient is to add these three things:
9 + 7 + 11 = 27.
We now know that those 27 were divided equally to each other, that is 27: 3.
So we just have to divide:
27: 3 = 9
In this way we can verify that each person obtained 9.
Divide 1017,36 by pi and by the height (the inverse of the formula for the volume):
1017,36/3,14 = 324
324/9 = 36
Answer:
x = 12
Step-by-step explanation:
The triangles are similar so we can use ratios
4x+12 32
------- = ------------
15 8
Using cross products
(4x+12) *8 = 15 * 32
(4x+12) *8 = 480
Divide each side by 8
(4x+12) *8/8 = 480/8
4x+12 = 60
Subtract 12 from each side
4x+12 -12 = 60-12
4x = 48
Divide by 4
4x/4 = 48/4
x = 12
An angle that measures 1/2 turn is 180 degree angle
Think of the three rectangles as a single large rectangle and find its area.
For the large rectangle made up of the three small rectangles:
Length = 8 cm + 15 cm + 17 cm = 40 cm
Width = 11 cm
area = length * width
area = 40 cm * 11 cm
area = 440 cm^2
