Given:
Kathy sells encyclopedias and earns $40 for each set she sells.
To Find:
How many sets did she sell if she earned $600 last week?
Solve:
Since kathy sells encyclopedias and earns $40 for each set she sells.
And if kathy total is $600
then we do
$600 divide by $40
600/40 = 15
Hence, she sold 15 sets last week.

A town population is 50,000 in 2018. The population has been growing at a rate of 3.7% each year. What is the estimated population of 2025?
Answer:
The formula for exponential growth is: Total = Starting value(1 + rate)^time
2018 to 2025 is 7 years:
Step-by-step explanation:
Total = 50,000(1+0.037)^7
Total = 50,000(1.037)^7
Total = 64,479 -(Answer)
Please Answer The Following Maths Question: "Could you change $2 for me for the parking meter?" inquired the young woman.
"Sure," I replied, knowing I had more than $2 change in my pocket.
In actual fact however, although I did have more than $2 in change, I could not give the woman $2.
What is the largest amount of change I could have in my pocket without being able to give $2 exactly?
Answer:
$5
Step-by-step explanation:
Conditions
More than $2Not exactly $2In the currency bills are printed as : $1, $5, $10, $20, $50, $100
Hence, the largest amount he could give the woman is $5
Which pair of angles are coterminal?
Answer:
5 pi / 9 & 23 pi / 9
Step-by-step explanation:
adding or subtracting multiples of 2pi are coterminal
2pi = 18pi/9
5 pi / 9 + 18pi/9 = 23 pi/9

A scale model of a skateboarding ramp is a right triangular prism as shown in the
figure.
In the actual ramp, the triangular base has a height of 15 in.
What is the VOLUME of the actual ramp?
Please explain in detail:)
The volume of the actual ramp including the underside is 16 cubic ft.
The height of the actual ramp = 15 feet
The height of the model = 6 cm
What is the volume of a right triangular prism?A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.
The volume of a right triangular prism = ( height× Base Area)
Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm
Actual base = 16 cm × 0.2 ft/cm = 3.2 ft
The volume of a right triangular prism = ( height× Base Area)
= [tex]5 \times 3.2\\ 16.0[/tex]
Hence, the volume of the actual ramp including the underside is 16 cubic ft.

Answer:
5
Step-by-step explanation:
a = 3
ab = 6
so b must be 2
3 squared is 9 and 2 squared is 4
so 9 - 4 is equal to 5
Answer:
Step-by-step explanation:
If a =3 and ab =6 then a²-b² =
a = 3
ab = 6
find b

Which values are solutions to the inequality below? Check all that apply.
x^2 > 16
A. 4
B. -6
C. -1
D. 5
Answer:
B. -6 and D. 5
Step-by-step explanation:
x^2 - 16 > 0
y = (x - 4)(x + 4) > 0
The critical point are x = -4 and x = 4
When x < -4, y > 0
When x > 4, y > 0
When -4 < x < 4, y < 0
When x = -4 and x = 4 , y = 0.
So the values that apply are
B. -6 and D. 5
there is a jar of 25 marbles. 9 of the marbles have a blue and black pattern. 6 of the marbles are purple. 10 of the marbles are green. one marble is chosen at random. what is the probability of picking to blue and black patterned marbles?
Answer:
Probability = 9/25
This is 36%
Step-by-step explanation:
To find the probability take the total number of possibilities (25 marbles--all of them) put that number on the bottom of a fraction. Then put the number of ways that outcome can happen (9 blue and black) and put that on top of the fraction.
Probability(event)
= specific/total
Probability(blu&blk)
= 9/25
If the fraction can be simplified, do that. 9/25 cannot be simplified.
If you need a percent for your answer, divide then multiply by 100.
A fraction bar is a division symbol.
9/25 means 9÷25.
9/25 = .36
Percent means "per hundred" To convert a decimal to a percent, multiply by 100
.36×100 is 36%
if the box is to be made out of wood that costs $4 per square foot, which of your designs would be less expensive to produce? Explain.
The second box is less expensive to make since it has a smaller surface area and hence requires less wood to construct the sides.
What is a cuboid?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape.
Here some data is not given, so we are assuming the volume of the box is 24 cubic feet.
If the volume is 24 cubic feet, the box's three dimensions must multiply to equal 24.
We can make two designs:
2 × 2 × 6 and 2 × 3 × 4.
Now, finding the surface area for each design.
First box
SA = 2wl + 2wh + 2hl
SA = 2×2×2 + 2×2×6 + 2×2×6
SA = 56 square feet
Second box
SA = 2×2×3 + 2×2×4 + 2×3×4
SA = 52 square feet
At $4 per square foot
For 56 ft², the price is $224
For 52 ft², the price is $208
Thus, the second box is less expensive to make since it has a smaller surface area and hence requires less wood to construct the sides.

Answer:
x = 24°
Step-by-step explanation:
angle BOC + angle BOA = 180°
angle BOC = 156°, angle BOA = x°
so x + 156° = 180°
=> x = 180° - 156° = 24°
so the measure of angle x is 24°

Answer:
37
Step-by-step explanation:
90 - 53 = 37
Answer:
x = 37°
Step-by-step explanation:
Given angle AOB = 53°, angle AOC = 90°
To find x°
From above figure, angle AOC = angle AOB + angle BOC
Now angle AOB = 53°, angle AOC = 90°
90° = 53° + angle BOC
=> angle BOC = x° = 90 - 53
=> x° = 37°
