Toby thinks of a number less than 15. He divides it by 2 and then he adds 4. He then divides it by 3. His awnser is 3. 5
Answer:
The number he thought of was 13
Step-by-step explanation:
Revers the problem
3.5 * 3 = 10.5
10.5 - 4 = 6.5
6.5 * 2 = 13
The number was 13 if Toby thinks of a number less than 15. He divides it by 2 and then he adds 4.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Toby thinks of a number less than 15. He divides it by 2 and then he adds 4.
Let the number be x:
From the question:
Revers the problem
x =(3.5×3 - 4)×2
x = (10.5 - 4)×2
x = 6.5×2
x = 13
Thus, the number was 13 if Toby thinks of a number less than 15. He divides it by 2 and then he adds 4.

4. Find the perimeter of the figure below. Use 3.14 for pi.
number answer.
Answer:
90.24 mm
Step-by-step explanation:
Circumference = 2πr
C = 2(3.14)(16)
C = 100.48 mm
Perimeter of the figure = 20 + 20 + 1/2 (circumference)
P = 40 + 1/2 (100.48)
P = 40 + 50.24
P = 90.24 mm

In order for you to carry a bag on the plane, it must fit inside the carry-on Baggage Check Box.
The carry-on Baggage Check Box has dimensions of approximately 22 inches x 14 inches x 9 inches.
Your black bag has a height of 18 inches, a depth of 12 inches and a width of 8 inches.
Your blue bag has a height of 18 inches, a depth of 15 inches and a width of 10 inches.
What is the volume of the Carry-on Baggage Check Box?
What is the volume of the black bag?
What is the volume of the blue bag?
Which bag will definitely fit in the Check Box? Explain.

You notice these two old suitcases stacked in the closet. The smaller suitcase is 25 inches x 8 inches x 9 inches and the larger suitcase is 75 inches x 20 inches x 18 inches.
The bigger suitcase is how many times larger than the smaller suitcase? HINT: You will need to divide on this one.
You decide to use the larger suitcase to transport rectangular prism watermelons back home. The watermelons are about 720 cubic inches. If one of the watermelons is about 10 inches long and 9 inches wide, about how tall would it be? (Hint: V=LxWxH, so plug h in 720=10x9xH and solve for H).
If the watermelons are about 720 cubic inches, what is the MAXIMUM amount of watermelons you’ll be able to bring home in your larger suitcase, assuming all you have in the suitcase is the watermelons. (Hint: Divide the larger suitcase volume and the volume of the watermelon).
The given dimensions of the, Check Box, bag, suitcase, and watermelons, we have;
First part;
Volume of the Check box is 2,772 in.³
Volume of the black bag is 1728 in.³
Volume of the blue bag is 2700 in.³
The bag that will definitely fit in the Check Box is; The black bagSecond part;
The number of times, the bigger suit case is larger than the smaller suit case is 15 timesThird part;
The height of the watermelon = 8 inchesThe maximum number of watermelon the larger suitcase can carry is 36 watermelonHow can the volume of the suitcases be found?Volume of the Carry-on baggage Check box, V_c can be found as follows;
V_c = 22 × 14 × 9 = 2772
Volume of the Check box, V_c = 2,772 in.³Volume of the black bag, V_b, can be found as follows;
V_b = 18 × 12 × 8 = 1728
Volume of the black bag, V_b = 1728 in.³Volume of the blue bag, V_bl, can be found as follows;
V_bl = 18 × 15 × 10 = 2700
Volume of the blue bag, V_bl = 2700 in.³Given that the height, depth and width of the black bag are smaller than the height, depth and width of the check box
The bag that will definitely fit in the Check Box is; The black bagSecond part;
Volume of the smaller suitcase is found as follows;
V_s = 25×8×9 = 1800
Volume of the bigger suitcase is found as follows;
V_b = 75 × 20 × 18 = 27,000
The number of times, the bigger suitcase is larger than the smaller suitcase is therefore;
n = 27,000 ÷ 1809 = 15
The number of times, the bigger suit case is larger than the smaller suit case is 15 timesThird part
The volume of the watermelon = 720 in.³
Which gives;
10 × 9 × H = 720
H = 720 ÷ (10 × 9) = 8
The height of the watermelon = 8 inchesTo maximize the number of watermelons, we have;
The length, 10, is a factor of 20
The width, 9, is a factor of 18
Therefore, we have;
Two rows of watermelon, and two layers of watermelon
Number of watermelon in a row is therefore;
R = 75 ÷ 8 ≈ 9
Maximum number of watermelon is therefore;
Max_n = 9 × 2 × 2 = 36
The maximum number of watermelon the larger suitcase can carry is 36 watermelonLearn more about finding the volume of a figure here:

the inverse of the function f(x)=-x+3
Answer: [tex]f^{-1}(x)=-x+3[/tex]
Step-by-step explanation:
To find the inverse of a function replace f(x) with x and replace the original x with y
[tex]f(x)=-x+3\\x=-y+3[/tex]
Now solve for y
[tex]x=-y+3[/tex]
First subtract 3 from both sides
[tex]x-3=-y+3-3\\x-3=-y[/tex]
Now divide both sides by -1 (this will make y positive)
[tex]\frac{x-3}{-1} =\frac{-y}{-1} \\-x+3=y[/tex]
Now replace y with the inverse of f(x), [tex]f^{-1}(x)[/tex]

Answer:
y - 2 = 6 (x - 1)
Step-by-step explanation:
Slope intercept form equations look like this:
y - y1 = m (x - x1)
***m = [tex]\frac{y2-y1}{x2-x1}[/tex]
Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:
y - 2 = m (x - 1)
To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.
[tex]\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6[/tex]
Now that we know m = 6, let's plug that back into the original equation to get our final answer:
y - 2 = 6 (x - 1)

A recycling bin is in the shape of a right rectangular prism. The bin is 9 meters long, 5 meters wide, and 313 meters tall.
What is the volume of the recycling bin?
Answer: 14085 m^3.
Step-by-step explanation: To find the volume of a right rectangular prism, you need to multiply the length, width, and height. The equation is below:
l x w x h = V where l is the length, w is the width, h is the height, and V is the volume of the right rectangular prism.
The length of this recycling bin is 9 meters, the width is 5 meters, and the height is 313 meters. Now that we know the length, width, and height, we can substitute the variables with the information we've gathered.
9 x 5 x 313 = 14085.
Therefore, 14085 m^3 is your answer.

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?
Answer:
$64.89
Step-by-step explanation:
57.68 + 1.25 × 57.68
= 57.68 + 72.1
= 129.78
The original price was $129.78.
129.78 – 0.50 × 129.78
= 129.78 – 64.89
= 64.89
The discount price was $64.89.

Answer:
C. 3/4 (third option).Step-by-step explanation:
Use the slope-intercept formula.
Slope-intercept formula:

The area of this figure.
square meters
10 m
2 m
12 m
7 m
4 m
4 m
Answer:
I believe it is 106 Square meters
Step-by-step explanation:
Easiest way to find area for these kind of shapes is to break them into smaller rectangles, this specific one can be broken 3 ways...
Right: 4m long, 7m tall
Top: 10 long, 5 tall *(12-7)*
Left: 4m long, 7m tall
*To find incomplete ones, you find clues in other sides, for instance the whole side was 12, the broken part was 7, therefor you just subtract 7 from 12, giving you 5 for the top.*
Then you just multiply...
4x7=28
4x7=28
10x5= 50
Now, you have the area for three individual smaller rectangles. So you simply add them together to get the whole shapes area...
28+28+50=106
Therefor, your answer should be 106 square meters- if I'm not mistaken.

In ΔOPQ, the measure of ∠Q=90°, OQ = 24, QP = 7, and PO = 25. What is the value of the tangent of ∠O to the nearest hundredth?
Answer: 0.29
Step-by-step explanation:
OQ is the side opposite angle P, QP is the side opposite angle O, and PO is the side opposite angle Q.
This means that tangent = opposite/adjacent, the tangent of angle O is the opposite side, QP, over the length of the adjacent side, OQ. (It cannot be PO since that's the hypotenuse)
This means that the tangent of O is 7/24, which is about 0.29
