A restaurant chef made 1 1/8 pints of mushroom soup. Each bowl of soup holds 1/8 of a pint. How many bowls of soup will the chef be able to fill?
Write your answer as a fraction or as a whole or mixed number.
Answer:
9
Step-by-step explanation:
We can determine the number of bowls that can be made by dividing the size of the bowl by the amount of soup. 1 1/8 can be expressed as 8/8 + 1/8, or 9/8. (9/8)/(1/8) = 9. The chef can fill 9 bowls of soup.
Mushroom soup sounds pretty good right now ngl

The height h in feet that a pole vaulter can reach can be estimated using the formula hu, where v is the velocity of the athlete in feet per
second.
If the height for a women's pole vault is about 9.8 feet, about how fast was the holder running? How far will the pole vaulter run in 2 seconds?
eet
feet per second
Using the numeric value of functions, it is found that:
The holder was running at a rate of 25 feet per second.The pole vaulter will run 50 feet in 2 seconds.How to find the numeric value of a function/expression?To find the numeric value of a function, we replace each instance of the variable by the desired value.
The formula for the velocity is given as follows:
[tex]v = 8\sqrt{h}[/tex]
In which h is the height.
For this problem, we have that the height is of h = 9.8, hence:
v = 8sqrt(9.8) = 25 feet per second.
The holder was running at a rate of 25 feet per second.
Then, in two seconds, the distance is given as follows:
d = 25 x 2 = 50 feet.
The pole vaulter will run 50 feet in 2 seconds.

In a class of 23 learners, the girls were 7 more than the boys. How many boys were in the class
Answer:
8 boys.
Step-by-step explanation:
Lets say b is the number of boys and g is the number of girls.
We know that:
23 = b + g
g = b + 7
So then lets solve for b:
23 = b + g
23 = b + ( b + 7)
Simplify.
23 = 2b + 7
Subtract 7 from both sides to isolate the b.
16 = 2b
Divide both sides by 2.
8 = b
So there are 8 boys in the class.
We can check our work by substituting the value of b into our equation.
23 = b + ( b + 7)
23 = 8 + ( 8 + 7 )
23 = 8 + 15
23 = 23
So therefore our answer is correct.

The Evans family paid $1,800 for a new refrigerator, washer, and dryer. The
refrigerator cost $250 more than the washer. The dryer cost half as much
as the washer. How much did the washer cost?
The cost of the washer based on the total cost of $1,800 of all three items is $442.86
How do represent the cost of the washer?
If we assume that the cost of the washer is x, based on that we can determine the cost of the refrigerator and the dryer while deriving from the cost of the washer as denoted below:
cost of washer=x
The cost of the refrigerator is $250 more than the cost of washer i.e. x+250
cost of dryer=0.5*x
cost of dryer=0.5x
total cost=x+x+250+0.5x
total cost=3.5x+250
total amount spent=1800
1800=3.5x+250

The shadow of a building is 30m long when the angle of elevation of the sun is 56°. Calculate the:
(a) height of the building
(b) length of shadow when the sun is at an angle of 32°.
Answer:
(a) height: 44.5 m
(b) shadow: 71.2 m
Step-by-step explanation:
You want building height and shadow length for angles of elevation 56° and 32°, given the shadow is 30 m when elevation is 56°.
Trig relationThe building height and shadow length are the sides opposite and adjacent (respectively) to the elevation angle in the right triangle that models the geometry. The trig function that relates these sides to the angle is the tangent function:
Tangent = Opposite/Adjacent
Application(a) building height
Using the tangent relation, we have ...
tan(56°) = (height)/(30 m)
height = (30 m)(tan(56°)) ≈ 44.4768 m
The height of the building is about 44.5 meters.
(b) shadow length
Using the same relation with the building height known, we have ...
tan(32°) = (44.4768 m)/(shadow)
shadow = (44.4768 m)/tan(32°) ≈ 71.1778 m
The length of the shadow at an angle of 32° is about 71.2 m.

11. You have just been hired as advertising manager of The Daily Chronicle, a not-very- successful newspaper. In the past, The Chronicle contained one-half advertising and one-half news stories. Current industry research indicates a newspaper must have three times as much advertising as news stories to make money. In addition, the advertising must be divided in the following ratio: 5 to 3 to 1, retail advertising to national advertising to classified advertising. The Chronicle is typically 48 pages in length. 1 a) How many pages should be advertising, and how many should be news stories? b) Based on the industry ratios, how should the pages be divided among the three types of advertising? c) After you made the changes in the advertising distributions ratios, your newspaper began making a profit—for the first time in years. If last year’s total advertising revenue was $810,000, how much was earned by each type of advertising? d) When you accepted the job of advertising manager, in addition to your salary, you were promised a 1/50 share of each year’s revenue from retail and classified advertising and a 1/75 share for national. What bonus will you receive for last year’s sales?
Using proportions, it is found that:
a) 36 pages should be of advertising and 12 pages should be of news stories.
b) 20 pages should be of retail advertising, 12 pages should be of national advertising and 4 pages should be of classified advertising.
c) $450,000 was earned by retail advertising, $270,000 was earned by national advertising and $90,000 was earned by classified advertising.
d) You will receive a bonus of $14,400 for last year's sales.
What is a proportion and what is an example of application?A proportion is a fraction of a total amount, and equations can be built to find the measures using a rule of three, that can be either direct or inverse, deriving from proportional relationships.
One example of application is for ratio problems, as fractions of the total amount are built from the ratios, as given in this problem.
For item a, we have that three times as much advertising as news stories are needed, hence 3/4 of the 48 pages are advertising, hence:
3/4 x 48 = 0.75 x 48 = 36.
Hence:
The remaining 12 are of news stories.
For item b, from the ratio of 5 to 3 to 1, we have that:
5/9 of the advertising pages should be of retail advertising.3/9 of the advertising pages should be of national advertising.1/9 of the advertising pages should be of classified advertising.Hence:
5/9 x 36 = 20 pages. -> Retail.3/9 x 36 = 12 pages. -> National.1/9 x 36 = 4 pages. -> ClassifiedIn item c, from the same ratio as above, the advertising values are found as follows:
5/9 x 810,000 = $450,000. -> Retail.3/9 x 810,000 = $270,000. -> National.1/9 x 810,000 = $90,000. -> ClassifiedFor item d, the bonus is calculated as follows:
1/50(450,000 + 90,000) + 1/75(270,000) = $14,400.
