As a prank, a friend decided to fill your car with balls from a ball pit. assuming the inside of your car is a rectangular prism
1 answer:
Answer:
D
Step-by-step explanation:
We need volume of rectangular prism and volume of sphere.
Volume of Rectangular Prism = length * width * height = 10 * 5 * 3 = 150 sq. ft.
3 inches is 3/12 = 0.25 ft
Volume of Sphere = sq. ft.
<em>How many of these can u fit in 150 sq. ft??</em>
<em />
<em>150/0.065 = 2307.69</em>
<em />
That's not one of the choices, but we can defnitely fit 2294 of the balls. So D is the correct answer.

Step-by-step explanation:
The quadrilateral ABCD consists of two triangles. By adding the area of the two triangles, we get the area of the entire quadrilateral.
Vertices A, B, and C form a right triangle with legs ,
, and
. The two legs, 3 and 4, represent the triangle's height and base, respectively.
The area of a triangle with base and height
is given by
. Therefore, the area of this right triangle is:
The other triangle is a bit trickier. Triangle is an isosceles triangles with sides 5, 5, and 4. To find its area, we can use Heron's Formula, given by:
, where
,
, and
are three sides of the triangle and
is the semi-perimeter (
).
The semi-perimeter, , is:
Therefore, the area of the isosceles triangle is:
Thus, the area of the quadrilateral is:
15×20×10=3000
10×20×15=3000
3000+3000=6000
10×20×15=3000
3000+3000=6000
Answer:
x = 0 and x = 1
Step-by-step explanation:
Given that,
A football is kicked into the air. The height of the football can be modeled by the equation :
Where
h is the height reached by the ball after x seconds
When it touches the ground, h = 0
So,
So, it will touch the ground at x = 0 and x = 1 seconds.
