18. A juice recipe calls for 3 1/2 cups
of sugar and will serve 60 people.
How much sugar would you need
if you reduced the recipe to serve
only 48 people?
A 4 2/3c B 3 1/2c C 2 4/5 c D 2 1/2c
Answer:
C. 2 [tex]\frac{4}{5}[/tex] cups
Step-by-step explanation:
We want 3.5 (3 1/2) cups of sugar that serves 60 people to serve 48 people instead. So we use proportions. Set it up:
[tex]\frac{x}{3.5} = \frac{48}{60}[/tex]
60x = 168 (48 x 3.5)
/60 /60
x = 2.8 cups of sugar serves 48 people.
Change 2.8 into fractions: 2 [tex]\frac{4}{5}[/tex]

Mason misses 25% of the free throws he attempts in a season. How many total free throws did he attempt if he missed 52?
Given:
Mason misses 25% of the free throws he attempts in a season.
Number of missed free throws = 52
To find:
The total number of free throws.
Solution:
Let x be the total number of free throws.
Mason misses 25% of the free throws he attempts in a season.
Number of missed throws = 25% of x
Number of missed free throws = 52
Now,
[tex]\dfrac{25}{100}x=52[/tex]
[tex]\dfrac{1}{4}x=52[/tex]
Multiply both sides by 4.
[tex]x=52\times 4[/tex]
[tex]x=208[/tex]
Therefore, the total number of free throws is 208.

f (x) = x + 5 and g(x) = 2x Find (f +g)(x)
Answer:
Step-by-step explanation:
f(x)=x+5 and g(x)=2x
(f∘g)(x)=f(g(x))=f(2x)=5+(2x)=2x+5
(g∘f)(x)=g(f(x))=g(x+5)=2(x+5)=2x+10
(f∘g)(x)=2x+5
(g∘f)(x)=2x+10
Kevin measured a line to be 12.4 inches long. If the actual length of the line is 15.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answer:
The percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]
Step-by-step explanation:
Estimated length of a line = 12.4 inches
Actual length of the line = 15.7 inches
Error = 15.7 - 12.4 = 3.3 inches
Percent error of the measurement [tex]=\frac{3.3}{15.7}(100)=21.02[/tex] ≈ 21.0
So, the percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]

Which of the following are point slope form of the line going through (-4,6) and (1,2)
Answer:
answer in comment
Step-by-step explanation:
So, we have to find the slope of the line. We are given two points, so we can use those:
(x1,y1) = (-4,6)
(x2,y2) = (1,2)
m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5
Also, we know that point-slope is of the form:
(y-y1) = m*(x-x1)
It doesn't matter which point you use, though, you can also use:
(y-y2) = m*(x-x2)
So we can plug the variables into the equation and get:
(y-2) = -4/5*(x-1)
OR
(y-6) = -4/5*(x+4)

Explain why a balance of less than - $10
represents a debt greater than $10.
Answer:
Answer down below.
Step-by-step explanation:
You can see that the 10 is negative. Now, imagine a number line. If you were to plot that on the number line, its less than 0. Anything in the positives is in the positive number range. If you were to do the same for negatives, it would represent a negative value, or in money standards, would be in debt.

You picked two marbles from a bag and record their color. How can you make your selections independent events? Dependent events?
Answer:
Let's suppose the next case:
We have a bag, where there are 5 red marbles, and 5 blue marbles.
We have a total of 10 marbles.
Suppose that we pick a marble and we do not replace it, and suppose that the first one is a red marble.
Then now we have in the bag a total of 4 red marbles and 5 blue marbles.
Now let's find the probability of picking a blue marble, this will be equal to the quotient between the number of blue marbles (5) and the total number of marbles (9)
P = 5/9
Now, suppose that instead of a red marble in the first pick, we had a blue marble.
Then now we have 4 blue marbles and 5 red marbles in the bag.
Again, the probability of picking a blue marble will be equal to the quotient between the number of blue marbles (4) and total numbergof marbles (9)
P = 4/9
Then the first pick does affect the probabilities for the second pick, this means that if we do not replace the first marble we pick, then the events will be dependent.
Now, if we replaced the first marble we picked (we put it again in the bag) then the number of blue marbles and red marbles is always the same, then in this case bot events will be independent (the first event will not affect the second event)

All four arms of a mechanical jack are the same length, and they form a parallelogram. Turning the crank pulls the arms together, raising the top of the jack. How high is the top of the jack when the crank is 5 inches off the ground? Explain.
Answer:
10 inches
Step-by-step explanation:
The top of the jack is 10 inches from ground.
What is parallelogram?A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.
Given Jack is in shape of parallelogram,
height of crank of jack from ground = 5 inches
to find the distance from ground to top of jack
since crank is at centre of jack and bottom to top of jack makes the diagonal of parallelogram,
distance from crank to top of jack is 5 inches,
because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.
total length from ground is 5 + 5 = 10 inches
Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths as much as yesterday, and food sales were down by $33.50. Nina wrote the expression
Complete question is;
Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths as much as yesterday, and food sales were down by $33.50. Nina wrote the expression ¾(1440) + 295.25 + (-33.50) to find today's total sales. Is she correct? Explain.
Answer:
Nina is correct
Step-by-step explanation:
Today, ticket sales were three-fourths as much as yesterday.
Thus, it means today's ticket sales will now be; $¾(1,440) = $1080
Now, food sales were down by $33.50.
Thus, food sales for today is;
$295.25 - $33.50 = $261.75
Thus,total ticket sales for today is;
1080 + 261.75 = $1341.75
From the expression of Nina which is ¾(1440) + 295.25 + (-33.50) ;
When calculated it gives the same value we got as $1341.75.
This means that Nina is correct
