Answer:
17 animals
Step-by-step explanation:
Rachel has a collection of 40 stuffed animals
3/8 are bears
= 3/8 ×40
= 120/8
= 15
1/5 are dogs
= 1/5×40
= 40/5
= 8
15+8
= 23
Therefore the number of animal she have left can be calculated as follows
= 40-23
= 17
Hence there are 17 animals left
Answer:
The answer to your question is below
Step-by-step explanation:
The formula to calculate the area of a circle = πr²
The formula to calculate the area of a cylinder = πr²h
The formula to calculate the area of a cone = 1/3πr²h
So, the correct answer to fill in the paragraph are:
1.- πr²
2.- πr²h
3.- 1/3
The statements that are true about circle Q are:
- The ratio of the measure of central angle PQR to the measure of the entire circle is 1/8.
- The area of the shaded sector depends on the length of the radius.
- The area of the shaded sector depends on the area of the circle.
<h3>How to explain the circle?</h3>
The measure of the central angle is 45°. The measure of the entire circle is 360°. This makes the ratio of the central angle to the entire circle 45/360 = 9/72 = 1/8
To find the area of the shaded sector, this will be:
A = πr² = π(6²) = 36π
1/8(36π) = 36π/8 = 18π/4 = 9π/2 = 4.5π square units. This is not 4 square units.
The ratio of the area of the shaded sector to the area of the circle would not be the same as the ratio of the length of the arc to the area of the circle.

Answer:
25
Step-by-step explanation:
There are 100 capsules and she can only buy 1/4
Multiply 100 * 1/4
100 * 1/4 =
100/4
25
We can check by calculating how many she leaves at the store
100 * 3/4 =
300 /4 = 75
The ones she bought , plus the ones she left behind should be 100 capsules
25+ 75 = 100
100 = 100
Check
Every 1 minute, you multiply the mass by 27.7% or 0.277
after 1 minute, you multiply once
after 2 minutes, you multiply twice
3, thrice
etc
so after 13 minutes, you multiply 13 times or 0.277^13
so what is 970g *0.277^13 =?
