EXPLANATION:
9/7 = 117/x solve for x
across multiply 9 with x and 7 with 117
9 x (x) = 9x
7 x 117 = 819
then you get 9x = 819 and you divide that
9x = 819
÷ 9 ÷9
the you get your x
x = 91
then add your original 117 and 91 to get 208
117 + 91 = 208

9. The plane would travel about 93.3 miles in 20 minutes.
EXPLANATION:
We know that the plane goes 280 miles per hour. And we only want one third of that hour (20 minutes). So you would just divide 280 by 3.
60 minutes (1 hour) = 280 miles
÷ 3. ÷ 3 divide by 3
20 minutes ≈ 93 miles

10. 67 cm
EXPLANATION:
You use the surface area formula for a rectangular prism which is A=2(wl+hl+hw)
A = 2·(0.5·7+4·7+4·0.5) fill in the blanks
(0.5·7+4·7+4·0.5) add your values together
A = 2 (33.5) multiply and find your answer
A = 67 cm

11. 174 mm
EXPLANATION:
First find the missing lengths. To find height of the bottom rectangle you would just do 15-9 which equals 6, and for the width you would add 14 + 6 which equals 20.
15mm - 9mm = 6mm
14mm + 6mm = 20mm
After you have all of your sides, you can do separate the rectangles to do the area formula. A = (L)(W)
A = (15mm)(6mm) which equals 90mm
A = (14mm)(6mm) which equals 84mm
Next you add the two sums together, and you have your area!
90mm + 84mm = 174mm
A= 174mm
——————————————————————
12.
EXPLANATION:
To find the mean of a data set, all you have to do is all of the numbers together, and divide by the amount of numbers in the data set.
1+4+8+12+4+10+15 = 54
54 ÷ 7 ≈ 7.7
Mean ≈ 7.7

Mr. Gibbs bought number of shirts for the new members of his band. The cost for number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts did Mr. Gibbs buy?
Answers
Answer:
Number of shirts= 6
Step-by-step explanation:
Giving the following information:
The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.
First, we need to calculate the net total price paid for the shirts:
Net total cost= 77.49 - 3.99= $73.5
Now, the number of shirts bought:
Number of shirts= 73.5 / 12.25
Number of shirts= 6

The oblique prism has a rectangular base with a width of 10 units and a length of 13 units. An oblique prism with a rectangular base is shown. The rectangular base has a width of 10 units and a length of 13 units. The distance between the top and the bottom base is 17 units. The top base extends 8 units to the right of the bottom base. The top base extends 8 units to the right of the bottom base. What is the volume of the prism? 1,040 cubic units 1,360 cubic units 1,950 cubic units 2,210 cubic units
Answers
Answer:
1,950 cubic units
Step-by-step explanation:
The computation of the volume of the prism is shown below:
Area of the rectangle = length × breadth
= 10 units × 13 units
= 130 units^2
Now the volume of the prism is
= Base × height
= 130 units × √(17^2 - 8^2)
= 130 units × 15 units
= 1,950 cubic units
Answer:
1,950 Cubic Units

If the length of SR is 4 meters and the length of ST is 8 meters , what is the length of PQ in meters
Answers
Answer:
the length of PQ is 8.9 m
Step-by-step explanation:
The computation of the length of PQ in meters is shown below:
Here we applied the Pythagoras theorem
c² = a² + b²
= 4² + 8²
= 16 + 64
= 80
Now square root to the both sides
c = √80
= 8.94427191
= 8.9 m
Hence, the length of PQ is 8.9 m

What is the surface area of the cone?

Answers
Hope this helps ❤️
The surface area of the cone is 56.52 in².
What is Surface Area?An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.
As per the given diagram:
slant height of the cone (l) = 7 inch
radius of the cone (r) = 2 inch
For the surface area of the cone:
= πr(l+r)
= (22/7) × 2 × (7 + 2)
= (396/7)
= 56.52 in²
Hence, the surface area of the cone is 56.52 in²

Answer:
divide by 4, 12, 21
Step-by-step explanation:
first, look at 20, and 5. How do you get there?
well, there are 2 possible ways.
20/4=5, or 20-15=5
we take it into the next pattern to get
44/4=11, and 44-15=29.
so now we know that the rule is to divide by 4
____________________________________________
36/4 = 12
84/4=21
Answer:
1. 36 / 4 = 9
2. 84 / 4 = 21
Rule: The input divided by 4. (I / 4 = O)
Step by Step explanation:
Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.
