Answer: E)1/4y=2x
Step-by-step explanation:
The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. If the constant of proportionality is 1/4, it means that the dependent variable is one-fourth the value of the independent variable.
So, we need to determine which equations have a constant of proportionality of 1/4:
A) y = 4x
The constant of proportionality in this equation is 4, not 1/4.
B) y = 0.25x
The constant of proportionality in this equation is 1/4.
C) 4y = x
The constant of proportionality in this equation is 1/4, since we can rewrite it as y = 1/4x.
D) 32y = 8x
We can simplify this equation by dividing both sides by 8:
4y = x
The constant of proportionality in this equation is 1/4.
E) 1/4y = 2x
We can rewrite this equation as:
y = 8x
The constant of proportionality in this equation is 8, not 1/4.
Therefore, the equations for which the constant of proportionality is 1/4 are B), C), and D).
Answer:
B, C, D
Step-by-step explanation:
You want to identify the equations that have a constant of proportionality of 1/4.
Proportional relationA proportional relationship can be written in the form ...
y = kx
where k is the constant of proportionality.
You want to identify those relations that are equivalent to this with k=1/4.
ChoicesA) y = 4x . . . . . k = 4 ≠ 1/4
B) y = 0.25x . . . . . k = 0.25 = 1/4
C) 4y = x ⇒ y = 1/4x . . . . . k = 1/4
D) 32y = 8x ⇒ y = 8/32x = 1/4x . . . . . k = 1/4
E) 1/4y = 2x ⇒ y = 2/(1/4)x = 8x . . . . . k ≠ 1/4
The relations with a constant of proportionality of 1/4 are B, C , D.

Mary has 400 slices of pizza. She gives 30 to Cambri,96 to Maria,99 to Falli,43 to Sam and 32 to Callin. How many slices does she have left?
Answer:
The answer to your problem is, 100 slices.
Step-by-step explanation:
First lets add up all the numbers that she gives away
30+96+99+43+32 =
300.
If she gave out 300 slices of pizza then here left over is:
400 - 300 = 100.
Thus the answer to our problem is, 100 slices.
Select ALL the expressions that are equivalent to -4(8x-3)
A) -20X
B) 4(3-8x)
C) -32x-12
D) 2(-16x+6)
E) 5-9(8x-3)
Answer:
B, D, and E
Step-by-step explanation:
-4(8x-3)= -32x+12
So we must choose the choices equivalent to this expression
A) -20x≠-32x+12
B)4(3-8x)≟-32x+12
12-32x=-32x+12
C)-32x-12≠-32x+12
D)2(-16x+6)≟-32x+12
-32x+12=-32x+12
E) 5-9(8x-3)≟-32x+12
40x-15-72x+27≟-32x+12
-32x+12=-32x+12

A restaurant uses c cups of flour for baking rolls and 12 cups of flour for baking pies each day. Use the Distributive Property to write an expression for how much flour the restaurant uses in seven days.
Answer:
7c + 84
Step-by-step explanation:
To find how much flour the restaurant uses in seven days, we need to multiply the amount of flour used per day by 7. We can use the distributive property to simplify this expression by factoring out the common factor of "c + 12":
Flour used in 7 days = 7(c + 12)
Expanding the expression, we get:
Flour used in 7 days = 7c + 7(12)
Simplifying, we get:
Flour used in 7 days = 7c + 84
Therefore, the expression for how much flour the restaurant uses in seven days is 7c + 84.

2 birds had 14 babies. The mom kept having babies for the next 43 years. How many babies did she have
Answer:
14x43=602 babies
Step-by-step explanation:
Is this the whole context of the problem? Going off of the idea that 14 babies are born every year each year the amount of birds would increase by 14. For example after two years (14x2) there would be 28 birds then after three years (14x3) there would be 42 so on so forth.

In a class in a middle school, there were 80 students. 30 percent were girls. How many of the class were boys. Awnser in percents.
Answer:
In a class of 80 students 30 are girls.
To Find:
The percentage of girls in the class is?
Solution:
The given problem can be solved using the concepts of percentages.
1. The total number of students in the class is 80, 30 are girls of the 80 members.
2. Percentage is given by the formula,
=> Percentage = (Favorable numbers x 100)/Total numbers,
3. Using the formula mentioned above the percentage can be calculated,
=> Percentage of girls = (30x100)/80,
=> (30x100)/80,
=> (3x100)/8,
=> (3x25)/2,
=> 75/2 = 37.5%.
Step-by-step explanation:
Answer:
70%
Step-by-step explanation:
If 30% of the class were girls, then 70% of the class must be boys (since 30% + 70% = 100%).
To find out how many students this represents, we can use the following formula.
70/100 * 80 = 56
So there were 56 boys in the class.
To express this as a percentage, we can calculate what percentage of the class the boys represent.
56/80 * 100 = 70%
Therefore, 70% of the class were boys.

Take the common denominator and add (in this case it will be 12)
9/12 + 6/12 + 8/12 + 7/12 = 30/12 = 5/2
Gio walked 2.5 miles
Answer:
She walked 2 7/12 miles.
Step-by-step explanation:
To start, we have to make sure we can add each fraction. One multiple they all have in common is 12. So we will change the denominator to 12. Remember, what you do to one side you have to do to the other!
To turn 3/4 into a 12, multiply by 3. 3x3 is 9 and 4x3 is 12 so 9/12.
To turn 1/2 into a 12, multiply by 6. 1x6 is 6 and 2x6 is 12 so 6/12.
To turn 2/3 into a 12, multiply by 4. 2x4 is 8 and 3x4 is 12 so 8/12.
And 7/12 is already in 12ths.
From there, we have to add the numerators.
9 + 6 + 8 + 7 = 31.
Now we have 31/12. We have to simplify this into a mixed number.
31 goes into 12 two times.
So we have 2 and 7/12 miles.
