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

On Monday the price of one share of Webb company stock was 24.85. By Friday the price was 25.004. By how much did the price change from Monday to Friday ?
Answers
Answer:
Change in price = 0.154
Step-by-step explanation:
Given that,
The price on Monday = 24.85
The price on Friday = 25.004
We need to find the change in price from Monday to Friday. It can be calculated as follows :
Change = 25.004 - 24.85
= 0.154
So, the required change in the price is equal to 0.154 .

Given the function F (x) = x2 -2x -5 determine the average rate of change of the function over the interval -5 < x <6.
Answers
Answer:
1
Step-by-step explanation:
Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.
The average value of a function f(x) over an interval [a, b] is
f(b) - f(a)
ave. val. = ---------------
b - a
which in this particular case is
19 - 30
ave. val. = ----------------- = -11/11 = 1
6 - (-5)
The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.

The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

Answers
Answer:

Step-by-step explanation:
i just took the test :)
The surface area of the given Square pyramid is 3456 square meters.
What is the Surface area?The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.
Given, a square pyramid with a base side of 36m and a slant height of 30m.
From the general formula of the surface area of the square pyramid,
Surface area = area of base + 4* area of triangle
Surface area = 36*36 + 4 * 1/2*36 * 30
Surface area = 3456 m²
therefore, the surface area of the given Square pyramid is 3456 square meters.

If each of the cubes in a Rubik's Cube represented 1 cubic inch, what would be the volume of the Rubik's Cube?
Answers
Answer:
The volume of the Rubik's Cube is 27 in^3
Step-by-step explanation:
Each face of a Rubik's Cube has 3x3 cubes, then each face has 9 small cubes.
We can think of a Rubik's Cube as 3 pieces, such that each piece has 9 small cubes on it, and the 3 pieces are: Front side, middle part, back part.
Then the total number of small cubes on a Rubik's cube is 9*3 = 27 small cubes.
Now we know that each one of these small cubes has a volume of 1 in^3
Then the volume of 27 of these cubes is 27 times the volume of a single smaller cube, then the volume of the Rubik's Cube is:
V = 27*( 1 in^3) = 27 in^3

Simple Interest = PRT
= 5000 × 4% × 1
= 5000 × 0.04 × 1
= 200
Now, the total savings will be the addition of the principal and the interest which will be:

The diagram shows:
base = 13height = xRecall that the area of a parallelogram is equal to the base times height
area = base*height
We're told that the area is 117 square units, so that means 13x = 117.
Divide both sides by 13 to isolate x
13x = 117
13x/13 = 117/13
x = 9
The height of the parallelogram is 9
Note how:
area = base*height = 13*x = 13*9 = 117
which helps confirm we have the correct height value for x.

Jane's cell phone plan is $58 each month plus $0.20 per minute for each minute over 200 minutes of call time. Jane's cell phone bill last month was $67.00. Write an equation that can be used to determine the number of minutes over 200 that Jane was billed. How many minutes over 200 was Jane billed last month?
Answers
Answer: 45 minutes more than 200
Step-by-step explanation:
So for every minute over 200 jane has to pay 0.20 cents per additional minute. The equation we can use is $58+0.20m=$67 where m is the amount of minutes after 200 jane has to pay 20 cents per
58+0.20m=67
0.20m=9
m=45
So Jane was billed for 45 minutes over 200 minutes last month. so in total 245 minutes and she was charged for the extra 45 minutes
