Answer:
9 boys are in the class
Step-by-step explanation:
5 to 8
5 x 3 = 15 girls
24 - 15 = 9 boys
9 boys in the class
There are 9 boys in the class.
What is Ratio?
A ratio indicates how many times one number contain in another number.
Given that;
In Mrs. Wilson's math class,
The ratio of girls to total students is 5 to 8.
Total student in the class = 24
Now, Let number of girls = 5x
And, Total number of student = 8x
Since, Total student in the class = 24
Hence,
8x = 24
x = 24/8
x = 3
Thus, Number of girls = 5x = 5 × 3 = 15
So, Number of boys = total student - number of girls
= 24 - 15
= 9
Thus, There are 9 boys in the class.

HELP!! **Linear Functions** Jackson needs to buy some new shirts and shorts to work out... Please show sufficient work, instead of just writing the answer. WILL GIVE BRAINLEIST FOR GREAT ANSWERS!!
Answer: 20: 10x + 20y = P
21: f(x) = -2y + 10
y can be 0 or even numbers from 2 to 10
Step-by-step explanation: 20:
The number of shirts times 10 is the price of the shirts. That is 10x in the equation.
The number of shorts times 20 is the cost of the shorts. That is 20 y in the equation. The total price, P, is the sum of 10x + 20y.
21: 10x + 20y = 100 This is the basic situation in standard form. Shirts and shorts add to 100
10x + 20y - 100 = 0 starting point to create the equation as number of shirts as a function of number of shorts. NOTE: this opposite of normal. Usually the y-value is the output.
10x = -20y + 100 . simplify
x = -2y + 10 This defines the number of shirts Jackson can buy based on the number of shorts.
The attached graph of the solution consists of 6 coordinates.
It is impossible to buy partial shorts or partial shirts. So, for example, if he buys 4 shorts, he can buy 2 shirts. If he buys no shorts, he can buy 10 shirts. Or if he buys 5 shorts he can buy no shirts. The question states that he must spend $100.
A baker uses 4.3 pounds of flour daily.
How many ounces of flour will he use in three weeks? Use words, numbers, or pictures to explain your thinking. (1 lb = 16 oz)
Answer:
The final answer will be 1444.8 oz.
Step-by-step explanation:
First you figure out how many oz are in 4.3 pounds. There are 68.8 oz. Then, since he uses 68.8 oz daily ( I suppose in a day) you multiply 68.8 x 7 and it gives you 481.6. Lastly, since we know the baker uses 481.6 in a week, you multiply that by 3 giving you 1444.8 oz. You're welcome and good luck <3.

Priscilla’s grandmother’s fruit salad recipe calls for one part apple, one part orange, four parts strawberry, two parts cherry, and three parts grape. Priscilla uses the same measuring cup to measure all of the fruit, so one part is equal to one cup of diced fruit. In this exercise, you will compare the quantities in the recipe to understand ratios better.
Part A
Write a sentence comparing the quantity of apples with the quantity of grapes.
Part D
Compare the total quantity of fruit used with the quantity of oranges. Write your answer in a sentence.

Answer:
What line is perpendicular to the line 2x + 3y = 6 through (4, 1)? Explanation: The given equation is in standard form, so it must be converted to slope-intercept form: y = mx + b to discover the slope is –2/3. To be perpendicular the new slope must be 3/2 (opposite reciprocal of the old slope).
Step-by-step explanation:
Help and explain why.
Answer:
y = 2x + 1
Step-by-step explanation:
In the x column we have the numbers 2, 4, 6, 9, and 12, if you were to take any of those numbers and multiply them by 2 then add 1, you would get the corresponding number in the y column.
For example:
X column = 2, 4, 6, 9, 12
Y column = 5, 9, 15, 19, 25
Each pair is (x,y) so pair one would be (2,5), pair two would be (4,9) and so on
So to check that y = 2x + 1 is really the right equation, substitute x for a number in the x column, and y for a number in the y column.
(5) = 2(2) + 1
This is correct because it would be 5=5
As you can see 5 does equal 5.
If you were to try this with any of the other equations it would not work.
For example:
y = 3x - 1
If you were to substitute the x and y values it would not work.
(9) = 3(4) - 1
3 * 4 is 12
12 -1 is 11
9 = 11
As you can see 9 does not equal 11

The perimeter of a square is equal to four times the length of one side.
A. p = 4 - x
B. p = x + 4
C. p = 4x
Answer:
C. p = 4x
Step-by-step explanation:
The square has four sides of the same length.
If the length of each side is "x", the perimeter is four times the length of each side, that is 4.x.

what is 4.2345 rounded to the nearest tenth
Answer to question:
4.2
Answer:
4.2
Step-by-step explanation:
The tenth spot would be the number right after the decimal. The number in the hundredths spot is the one that determines what happens to the number in the tenths spot.
If the number in the hundredths is 5 or more, you would round the number in the tenths spot up one.
If the number in the hundredths spot is 4 or less, you would keep the same number in the tenths spot.
Since the number in the hundredths spot is 3, you would leave the number in the tenths place the same (2).

Robb’s Fruit Farm consists of 100 acres on which three different types of apples grow. On 25 acres, the farm grows Empire apples. McIntosh apples grow on 30% of the farm. The remainder of the farm grows Fuji apples. Shade in the grid below to represent the portion of the farm each type of apple occupies. Use a different color for each type of apple. Create a key to identify which color represents each type of apple.
Answer:
Shade in 25 squares yellow. Next shade in 30 squares green. Then shade the remainder of the squares red. For the key, Empire will be yellow and the ratio would be 25/100 or 1/4. For McIntosh, that is the green and the ratio is 30/100 or 3/10. Finally, for Fuji, that is the red and the ratio will be 45/100 or 7/20.
Step by Step Answer:
25 for Empire because it says 25 acres. 30 for McIntosh because 30% of 100 is 30. To find Fuji, you add the 25 and 30 to get 55. You then subtract the 55 from 100 to get 45.

200% of $5( please help)
Answer:
I think its 10
Step-by-step explanation:
hope this helps
Answer:
$10
Step-by-step explanation:
We know that when we see %, that is a clue to divide that number by 100.
Here, we have 200%, which is the same as 200/100 = 2.
In mathematics, "of" almost always is an indication to multiply, so we multiply 2 by 5:
2 * 5 = $10
The answer is $10.
