Question
Craig is designing a new cylinder-shaped can for a pet food company. He wants the height of the can to be 40 mm and the radius of the can to be 1 3/8 times the height of the can. He models the can on a coordinate grid as a rectangle in the first quadrant that will be rotated around the y-axis to create the 3-dimensional can. What will be the diameter of the can?
Solution 1
The height of the can for this case is given by:
h = 40 mm
The radius of the can is given by:
r = (1 3/8) * h
Substituting values:
r = (1 3/8) * 40
r = 55 mm
Therefore, the diameter of the can is:
d = 2 * r
d = 2 * 55
d = 110 mm

The diameter of the can will be:

d = 110 mm
Question
What are the factors of x^2-64
Solution 1
Difference Of Two Squares
a^2 - b^2 = a^2 - b^2
so
x^2-64
=x^2 - 8^2
= (x + 8)(x - 8)
Question
What is a correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9?
Solution 1
Use the distributive property to simplify the left side

-12 + 20x >= -6x + 9
Solution 2
In order to solve the inequality, You need to work the parenthesis, -4(3-5x)>-6x=9.
-12+20x>-6x+9
-12+26x>9
26x>21
Now divide both sides by 26, and the answer is:
Answer: x is greater than or equal to 21/26 (21 over 26)
Question
A gumball machine contains 23 green gumballs, 52 red gumballs, 34 blue gumballs, 61 yellow gumballs, and 30 pink gumballs. What percentage of the gumballs are red?
Solution 1
So percent means parts out of 100
x%=x/100
so we jsut have to find
(red)/(total)
red=52
52/200
make bottom number 100
26/100=26%
Question
Which of the following is an undefined term? Angle Circle Plane Ray
Solution 1

Plane is an undefined plane

Step-by-step explanation:

Hi, there are three undefined terms in geometry: point, line, and plane.

Point: has no size, only location . It can be named with a capital letter.

Plane: a flat surface that has no thickness, that extends infinitely n every direction.  Is named  by a single letter or by three coplanar, but non-collinear, points.

Line: Set of points extending in either direction infinitely.

Angle, circle, and ray are not undefined terms.  are not Plane.

Solution 2
I think it would be C.plane... I had this question a while ago and I think its right... plz tell me if I am wrong. Thanks.
Question
A triangle has an area of 36 square feet. If the height of the triangle is 6 more feet than its base, what is its height and base?
Solution 1
If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.

Question
Factor completely 2x^3+6x^2+2x+6
Solution 1
2x^3+6x^2+2x+6
= 2(
x^3 + 3x^2 + x +  3)
= 2[x^2 (x + 3) + (x + 3)]
= 2(x^2 + 1)(x + 3)

hope it helps
Solution 2
F(-3) = 2*-27 + 6*9 + 2*-3 + 6 =  0

so x + 3 is a factor

dividing the function by x + 3  gives the quotient

2x^2 + 2   = 2 (x^2 + 1)

So the factors are 2(x^2 + 1)(x + 3)  Answer
