Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.
Answer:
52 cm
Step-by-step explanation:
The only tricky part is getting the not measured side. However, you have a portion of it. 16-11=5, and that is the missing side. Then just add everything together.

Find the volume of the triangular prism to the right.
5 ft
10 ft
The volume of the prism is ? ft^3
Answer:
rectangular is 114ft and triangular is 112ft
Step-by-step explanation:
Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT
Since VR = length * width and height
VR = 6*x*3
VR = 18x ft³
Also VT = Length *width * Height/2
VT = (7 * x * 4)/2
VT = 28x/2
VT = 14xft³
Since VR = 32 + VT
18x = 32+(14x)
collect like terms
18x-14x = 32
4x = 32
divide both sides by 4
4x/4 = 32/4
x = 8
Volume of the rectangular prism = 18x
Volume of the rectangular prism = 18*8
Volume of the rectangular prism = 144ft³
Volume of the right triangular prism = 14x
Volume of the rectangular prism = 14*8
Volume of the rectangular prism = 112ft³

Mr. Chau is planting a circular flower garden in his backyard. If the diameter of his garden is 12 feet, what is the area of the garden?
Answer:
A = 113.04 ft² or 36π ft²
Step-by-step explanation:
Area of a circle: πr²
radius: d/2 (12/2 = 6 ft)
π (pi) = 3.14
Solve:
A = πr²
A = 3.14(6)²
A = 3.14(36)
A = 113.04 ft² or 36π ft²

To solve this problem, you have to find the value of x to isolate it on one side of the equation.
-2x=14First, you divide by -2 from both sides.
-2x/-2=14/-2
Solve.
Divide these numbers from left to right.
14/-2=-7

Step-by-step explanation:
Hardware store:
4 bulbs = $20
1 bulb = $20 / 4 = $5
Grocery store:
6 bulbs = $24
1 bulb = $24 / 6 = $4
The difference in price = $5 - $4 = $1
The grocery store sells at the lesser price.
So, the grocery store charges $1 less per light bulb than the hardware store.
Kevin is an auto mechanic. He spends 3 hours when he replaces the shocks on a car and 2 hours when he replaces the brakes. He works no more than 36 hours a week. He routinely completes at least 2 shocks replacements and 3 brake replacements a week. If he charges $400 for labor replacing shocks and $200 in labor for replacing brakes, how many jobs of each type should he complete a week to maximize his income?
Answer:
See below ....question is a bit unclear
Step-by-step explanation:
He makes 133.33 per hour with shocks and only 100 per hour with brakes.
he should only do 36/3 = 12 shock jobs per week and no brakes.
if he HAS to do at LEAST 3 brake jobs
then he should do 3 brakes and 10 shocks

The interest amount per year is
3% of $2500 = 3*2500/100 = 75Number of years is
150/75 = 2Answer:
2 years
Step-by-step explanation:
Simple Interest Formula
I = Prt
where:
I = total interest earnedP = principalr = interest rate (in decimal form)t = time (in years)Given:
P = $2500r = 3% = 0.03I = $150Substitute the given values into the formula and solve for t:
⇒ 150 = 2500(0.03)t

∠A and \angle B∠B are complementary angles. If m\angle A=(x+10)^{\circ}∠A=(x+10)
∘
and m\angle B=(3x+28)^{\circ}∠B=(3x+28)
∘
, then find the measure of \angle B∠B.
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28

Two vertices of a rectangle are located at (6, 1) and (8, 1). The rectangle has an area of 18 units2 and is entirely in the first quadrant. What are the other two vertices?
The two other two vertices will be (6, 10) and (8, 10)
How to calculate the area of a rectangle?A rectangle is a 2-dimensional shape with equal opposite sides. The formula for calculating the area is given as:
Area = length * width
Given;
Area = 18 square units
Length = x2 -x1 = 8 -6
length = 2 units
Determine the width
Width = A/l
Width = 18/2
Width = 9 units
Hence the two other two vertices will be (6, 10) and (8, 10)

The volume of a tree stump can be modeled by considering it as a right cylinder. Justin measures its circumference as 84 in and its volume as 20214 cubic inches. Find the height of the stump in feet. Round your answer to the nearest tenth if necessary.
The height of the stump tree which can be modeled by considering it as a right cylinder is 35.9 inches.
What is a cylinder?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )
Since the base of a cylinder is circular in shape, the circumference is expressed as;
C = 2πr
Given that the circumference of the base is 84 in, we can now calculate the radius r.
C = 2πr
84in = 2 × 3.14 × r
84in = 6.28 × r
r = 84in / 6.28
r = 13.4in
Now, the Radius of the cylinder r = 13.4in and its volume = 20214in³, we substitute this values into the expression for volume of cylinder above to find the height h.
V = π × r² × h
20214in³ = 3.14 × ( 13.4in)² × h
20214in³ = 3.14 × 179.56in² × h
20214in³ = 563.8in² × h
h = 20214in³ / 563.8in²
h = 35.9in
Therefore, the height of the stump tree which can be modeled by considering it as a right cylinder is 35.9 inches.
