Answer:
39
Step-by-step explanation:
There are 8 pints in a gallon, so 5 1/2 gallons is (5.5)(8 pints) = 44 pints.
If 5 remain, then 44-5 = 39 were spilled.
39 pints of water spilled from the bucket.

Step-by-step explanation:
Answer: f(3.5) = 58.20
Step-by-step explanation:
Wow...what degree of exponent are we to assume?
I'll go with 2 as we are only given two exemplars.
f(x) = x² + Ax + B
f(- 2.5) = 9 = (-2.5)² + (-2.5)A + B
f(2.5) = 45 = (2.5)² + (2.5)A + B
we can subtract the first equation from the second
45 - 9 = 2.5² - (-2.5)² + 2.5A - (-2.5A) + B - B
36 = 5A
A = 7.2
45 = (2.5)² + (2.5)7.2 + B
B = 20.75
F(3.5) = 3.5² + 7.2(3.5) + 20.75 = 58.2
Answer:
7 sheets
Step-by-step explanation:
Dimension of gabble = 42' by 5'
Dimension of standard plywood sheet : 4' by 8'
Area that will be covered by gabble :
Length * width :
42 * 5 = 210 in²
Area covered by 1 plywood sheet :
4 * 8 = 32 in²
Number of plywood sheets required :
Area of gabble / Area of 1 plywood sheet
210 in² / 32 in²
= 6.5625
This means the number of plywood sheets that will be required is 7

Answer and Explanation:</h2><h2 />
The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:
From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:
Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation 
. An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.
