A nutritionist is filling a container of nutritional powder supplement. She wants to ensure there is
a 20 : 3 ratio of protein to fiber in the powder supplement in the container. If the nutritionist puts 300 grams of protein into the container, how many total grams of powder supplement will
the container have?
A.) 15
B.) 45
C.) 345
D.) 369
Answers
Answer:
A
Step-by-step explanation:
The the container will have total 345 grams of powder supplement.
Thus, the correct answer is C.)345
What is the ratio?A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.
Now given that,
ratio of protein to fiber in the powder supplement = 20 : 3
grams of protein into the container = 300
Now let x be the number.
So, grams of protein into the container = 20x
and, grams of fiber into the container = 3x
Since, grams of protein into the container = 300
⇒ 20x = 300
⇒ x = 15
So,total grams of powder supplement in the container = 20x + 3x
⇒ total grams of powder supplement in the container = 20*15 + 3*15
⇒ total grams of powder supplement in the container = 300 + 45 = 345
Thus, the the container will have total 345 grams of powder supplement.
Thus, the correct answer is C.)345

Skylar owns a small business selling bagels. She knows that in the last week 80 customers paid cash, 7 customers used a debit card, and 42 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.
Answers
Answer:
The probability that the next customer will pay with credit card is approximately 0.33
Step-by-step explanation:
The given parameters are;
The number of customers that paid cash = 80 customers
The number of customers that used a debit card = 7 customers
The number of customers that used a credit card = 42 customers
The total number of different payments made = 80 + 7 + 42 = 129 payment
Probability = The number of desired outcome/(The number of possible outcome)
The probability that the next customer will pay with credit card = (The number of customers that used a credit card)/(The total number of different payments made)
∴ The probability that the next customer will pay with credit card = 42/129 ≈ 0.33 to the nearest hundredth.

Liberty Center Middle School has 1,200 students. In Sophia’s class, 3 out of 4 students borrowed library books. Based on these results, how many students at the school would you expect to borrow library books?
Answers
Answer:
We expect 900 students to borrow library books
Step-by-step explanation:
Proportions
If two variables are proportional, then one of them can be obtained as the other times a fixed number.
If x and y are proportional, then:
y=k.x
Where k is the constant of proportionality
The value of k can be obtained by dividing y/x.
That division, also called ratio gives us the proportion to be applied to future calculations.
In Sophia's class, 3 out of 4 students borrowed library books.
This gives us a proportion ratio of 3/4.
If we apply that same proportion to the rest of the Liberty Center Middle School, with 1,200 students, then, we expect to have
3 / 4 * 1200 = 900 students borrowing library books.
We expect 900 students to borrow library books

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of the line on the graph is given as:
y = mx + c ____(1)
The graph on option A.
If the equation of a line is y = mx and the slope is a unit rate the graph shows proportional relationships.
We will select two points on the graph.
i.e
(2, 2) = (a, b) and (3.3) = (c, d)
Slope:
m = (d - b) / (c - a) = 3 - 2 / 3 - 2 = 1 / 1 = 1
Let (2, 2) = (x, y) and putting in (1) we get,
2 = 1 x 2 + c
2 = 2 + c
c = 2 - 2 = 0
c = 0
The slope of the line is 1
The equation of the line is y = x
Thus,
The graph displays a proportional relationship.
Option A is the correct answer.

How can we change 1 litre into 1000cm3
Answers
To change from litres into cubic centimetres, you times the value by 1000.
Eg:
Imagine the question “turn 5 litres into cm³”
First step would be to figure out how many litres we have, which is 5.
Now, we multiply 5 by 1000, which gives us 5000.
Therefore 5 litres = 5000cm³
I hope this helps and made sense, if you have any more questions or need me to explain further, just ask! :)
(If I helped you at all I’d greatly appreciate a thanks or if I really helped you a Brainliest!)
Step-by-step explanation:
1 Liter (L) is equal to 1000 cubic centimeters (cm3). To convert liters to cubic centimeters, multiply the liter value by 1000. For example, to convert 2 liters to cubic centimeters, multiply 2 by 1000, that makes 2 L is 2000 cm3.
Greg earns a salary of $300 per week plus an additional
6% commission on his sales. If his weekly salary
increases by $50 and his commission increases to 7%
how much will Greg earn if his weekly sales are
$4,000?
Answers
Given :
Greg earns a salary of $300 per week plus an additional 6% commission on his sales.
To Find :
If his weekly salary increases by $50 and his commission increases to 7% how much will Greg earn if his weekly sales are $4,000.
Solution :
New weekly salary, S = $( 300 + 50 ) = $350 .
New commission on $4000 sales :
[tex]C=\dfrac{4000\times 7}{100}= \$280[/tex] .
Therefore, total earning T = S + C = $( 350 + 280 ) = $630 .
Hence, this is the required solution.
