Answer:
267.947 cm^{3} of gel is required to fill the plastic ball.
Step-by-step explanation:
<em>The radius of the ball is given as 4 cm.</em>
<em>The gel is filled in the plastic ball, that means the gel occupies the volume of the radius.</em>
The volume of the sphere is given by the formula,
, the R is the radius of sphere.
Thus, the volume of gel required to fill the plastic ball to make it stress ball is
267.947 cm^{3} of gel.
Answer:
The dimension of the rectangle is 19mm by 73mm
Step-by-step explanation:
In this question, we are tasked with calculating the dimensions of the rectangle given the information in the question.
Let the width of the rectangle be x, we are told that length is 3mm less than four times width
Mathematically this means l = 4x - 3
Now we are given the area, what this means is that when we multiply the width and the length, we get the area value
Thus, mathematically
x(4x - 3) = 1,387
4x^2 - 3x = 1387
4x^2 - 3x - 1387 = 0
Solving the quadratic equation, we have;
x = 19 or -73/4
since length cannot be negative, we ignore -73/4
Now the length = 4x - 3 = 4(19) - 3 = 73mm
Thus the dimension of the rectangle is 19mm by 73mm
Answer:
exactly two factors
Step-by step Explanation:
A prime number is an integer, or whole number, that has only two factors: 1 and itself. Put another way, a prime number can be divided evenly only by 1 and by itself. Prime numbers also must be greater than 1. For example, 3 is a prime number, because 3 cannot be divided evenly by any number except for 1 and 3.
First find the lbs per serving for the 25 servings. We do that by dividing 6 pounds by 25 serving. 6/25 = .24 lbs per serving. Now we need to times .24 by 30 to find out how many pounds of ground beef for 30 servings.
.24 times 30 = 7.2 lbs for 30 servings
