To find the percent of the birdhouses occupied, divide the number of occupied birdhouses by how many birdhouses there are in total:
![4 \div 76 = 0.0526](https://tex.z-dn.net/?f=4%20%5Cdiv%2076%20%3D%200.0526)
Convert this decimal into a percentage by multiplying by 100:
5.26% of the birdhouses are occupied.
Answer:
9.6 cm
Step-by-step explanation:
Since the scale factor is 3 (you can figure that out by dividing the larger side of the triangle by the one on the smaller triangle that is the same side) you would divide all other sides by 3 to find individual lengths.
9.6/3 = 3.2
7.2/3 = 2.4
We already know the other side, 4.
3.2 + 2.4 + 4 = 9.6cm
Answer:
430 > 33.73x + 27 ----> x < 11
Step-by-step explanation:
The inequality describes the total amount that can be spent for a whole number of days. To solve for the number of days, solve for x (x<11.95). Because she can't rent for only a part of a day, and because she can't spend more than $430, the inequality becomes x<11.
Answer:
28.3 square inches
Step-by-step explanation:
In the question, we are asked to calculate the portion of the area of the cake eaten by Ellie’s sister.
To calculate this, the first thing to do is to calculate the area of the cookie cake. Now, since it’s a round cake, then it must be circular in shape.
Hence we calculate the area.
mathematically the area of a circle can be calculated using the formula;
A = pi * r^2
here our r =6 inches
Substituting this, we have
A = 22/7 * 6 * 6 = approximately 113 sq. inches
we now move on to calculate the portion ate, which is a quarter
That would be 1/4 * 113 = 28.3 sq. inches was eaten
25% is 1/4 so you do 8 times 1/4 and that's 2.
