Step-by-step explanation:
1 kg = 1000 grams
1 min = 60 sec
360 kg (1000grams/1 kg) = 360000grams
360000 grams/min (1 min/ 60sec) = 6000 grams / sec

Find the surface area of the prism.
Answer and Step-by-step explanation:
To find the surface area, all you have to do is find the area of each face of the prism, and then add them all together.
15 x 20 = 300
(15 x 8)/2 = 60
(15 x 8)/2 = 60
(There are two triangles)
8 x 20 = 160
20 x 17 = 340
Now, add them all together.
300 + 60 + 60 + 160 + 340 = 920
The surface area of the prism is 920 [tex]units^{2}[/tex]

David purchased these school supplies: 5 notebooks for $1.29 each 2 pens for $1.19 each 12 pencils for $0.05 each 6 erasers for $0.15 each How much change should David receive from $20?
Answer:
The answer is $9.67.
Step-by-step explanation:
Notebooks: 5 * 1.29 = 6.45
Pens: 2 * 1.19 = 2.38
Pencils: 12 * 0.05 = 0.60
Erasers: 6 * 0.15 = 0.90
Total: 6.45 + 2.38 + 0.60 + 0.90 = 10.33
Change: 20 - 10.33 = 9.67

hannah spends 20% of her money on sweets and 32% on fares. if she spent $8 on sweets what is:
(1) the amount of money she originally had?
(2) the amount of money spent on fares?
(3) the amount she has left?
Answer:
1) $40
2) $12.80
3) $19.20
Step-by-step explanation:
(a) find: 8 is 20% of what number
use proportion: is = percent
of 100
is = 8
of = what you're solving for, let's say 'x'
20% = 20/100
8 = 20
x 100
cross-multiply: 20x = 800
x = 40
(b) money spent on fares: 32% of 40 is what number?
32 = y
100 40
1280 = 100y
y = 12.80
3) 40 - (8.0 + 12.80) = 40 - 20.8 = 19.20
Find the slope plssss
Answer:
5/2
Step-by-step explanation:
Answer:
The slope of this line is - 5/2.
Step-by-step explanation:
In order to get from one red dot to another, you must go up 5 and to the left 2, because we are going left instead of right, the slope is negative. It doesn't matter which number you assign the negative sign. The entire formula for the line is y=- 5/2x - 3

Mr. Green paid $7.50 for a set of dry erase markers. He used a $2.00 coupon for his purchase. Write AND solve an equation that represents the difference between d, the original price of the markers and the coupon. Solve for d.
Answer:
[tex]d - 2 = 7.50[/tex]
$9.50
Step-by-step explanation:
Given that:
Money paid by Mr. Green for a set of dry erase markers = $7.50
Coupon used for the purchase = $2.00
To find:
The equation and solution to represent the difference the original price [tex]d[/tex] of the markers and the coupon.
Solution:
Given that, the original price of the dry erase markers = $[tex]d[/tex]
Coupon amount = $2.00
Amount paid = $7.50
The equation can be made by subtracting the coupon amount from the original price and comparing it with the amount paid by Mr. Green for the purchase.
Original price = $([tex]d[/tex] - 2)
[tex]d - 2 = 7.50[/tex]
Solving the above equation by adding 2 on both the sides:
[tex]d -2+2= 7.50+2\\\Rightarrow d = \$9.50[/tex]
Standardized tests for certain subjects, given to high school students, are scored on a scale of 1 to 5. Let X represent the score on a randomly selected exam. The distribution of scores for one subject’s standardized test is given in the table.
A 2-column table with 5 rows. Column 1 is labeled score with entries 1, 2, 3, 4, 5. Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
What is the mean of the distribution?
2.5
2.95
3
3.5
Answer:
The center for the distribution of scores appears to be higher for subject B than for subject A.
The mean of the distribution when X represent the score on a randomly selected exam so here the mean be like 2.95.
Calculation of the mean:Since
Column 1 is labeled score with entries 1, 2, 3, 4, 5.
Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
So it be like
= (0.18) (1) + (0.20) (2) + (0.26) (3) + (0.21) (4) + (0.15) (5)
= 0.18 + 0.40 + 0.78 + 0.84 + 0.75
= 2.95
Hence, the third option is correct.

Write the slope-intercept form of the equation of the line through the given points: (-2,13) and (4,1)
Answer: y = -2x + 9
Step-by-step explanation:
Points through which the line passes through are: (-2,13) and (4,1)
The slop intercept form will be in terms of:
y = mx + c
Find m first which is the slope:
= (Y₂ - Y₁) / (X₂ - X₁)
= (1 - 13) / (4 - (-2))
= -12 / 6
= -2
Using a point on the line and the slope, calculate c which is the y intercept:
Using point (-2,13) :
y = mx + c
13 = -2 * -2 + c
13 = 4 + c
c = 13 - 4
c = 9
Slope intercept form of line is therefore:
y = -2x + 9

A company produces two different sizes of soup cans. The volume of the cans varies jointly with the square of the can's radius and the height. The smaller can has a height of 5 inches, a squared radius of 4 inches, and a volume of about 62.8 cubic inches. What is the volume of the taller can, which has a height of 9 inches and a squared radius of 4 inches? Round to the nearest tenth, as needed.
A. V=113.0
B. V=36.0
C. V=3.1
D. 91.3
Answer:
A. V= 113 in³Step-by-step explanation:
Volume formula will be:
V = kr²h,where V - volume, k - coefficient of proportion, r² - squared radius, h - height
Substitute the known values to find the unknown:
62.8 = k*4*562.8 = 20kk = 62.8/20k = 3.14Now find the volume of the taller can:
V = kr²hV = 3.14*4*9 = 113.04 ≈ 113 in³Correct option is A
A=113.0

Factor to find the zeros of the function:
y = 8x2 + 8x - 96
-0)
A)
x = 4 or x = 3
B)
X = -4 or x = 3
X = 4 or x = -3
D)
x = -4 or x = -3
Step-by-step explanation:
y = 8x² + 8x - 96
y = 8(x² + x - 12)
y = 8(x + 4)(x - 3)
When y = 0, 8(x + 4)(x - 3) = 0.
=> x = -4 or x = 3. (B)

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent the relationship between her labeling speed and the number of minutes it would take her to finish labeling. Complete the equation below: m = _________ where m is the number of minutes and s is the speed in books per minute.
Answer:
[tex]S = \frac{b}{m}[/tex]
Step-by-step explanation:
Given
[tex]Speed = s[/tex]
Required
Determine the expression for s
The speed is calculated as:
[tex]Speed = \frac{Number\ of\ books}{Time}[/tex]
Substitute S for speed
[tex]S= \frac{Number\ of\ books}{Time}[/tex]
Let the number of books be b and the time be m.
The expression becomes
[tex]S = \frac{b}{m}[/tex]
Hence, the expression for the scenario is:

Answer:

Step-by-step explanation:
on edg 2021 ^u^
The width of the tower at the top will be 92 m. Then the correct option is B.
What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
A cooling tower is 120 meters tall.
The sides of the tower are in the shape of a hyperbola defined by the equation x²/500 – y²/900 = 1 with units in meters.
The center of the tower is at the origin.
Then the width of the tower at the top will be
x²/500 – (120)²/900 = 1
x²/500 – 14400/900 = 1
x²/500 – 16 = 1
x²/500 = 1 + 16
x²/500 = 17
x² = 8500
x = 92.19 ≈ 92 m
Then the correct option is B.
