Answer:
4
Step-by-step explanation:
You have to find the volume by dividing the diameter in half, which is 1, and then the volume is 4.19, and that rounds to 4.
Answer:
85%
Step-by-step explanation:
There are two ways to solve this.
1. You can find the percent of birds, and then subtract that from 100%.
To find the percent of birds, divide 45/300 or make the denominator 100 by dividing both parts by 3.
45/300 (as a fraction)
=15/100
That is the same as 15%.
Subtract that from 100% and you get 85%.
2. You find the number of non-bird animals and make that a percent.
300-45=255 non-bird animals
255/300 (as a fraction)
=85/100
That is the same as 85%.
So either way, the answer is 85%.
Answer:
62°
Step-by-step explanation:
In an isosceles triangle, angle opposite to equal sides are equal.
So according to angle sum property :
x + x + 56 = 180
2x + 56 = 180
x = 180 - 56 /2
x = 62°
Answer: D. A square with side length of 20 feet.
Step-by-step explanation:
To determine the side length of the square that could be connected to side b of the triangle to correctly complete the model, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Hypotenuse = side length of square C
Adjacent side = side length of square A
Let B represent the side length of the required square.
Area of square = (side length)²
Therefore,
841 = 441 + B²
B² = 841 - 441 = 400
B = √400
B = 20 ft
