Ellie bought cookies and cupcakes from Publix for $102.44. If she spent $36.44 on cookies and the cupcakes are $11 per box, which equation represents this situation?
A)11x - 36.44 = 102.44
B)102.44x + 11 = 36.44
C)11x + 36,44 = 10244
D)102.44 + 36.44x = 11

Answers

Answer:

C

Step-by-step explanation:

She spent $102.44 in total.

She spent $36.44 on cookies.

And $11 per box of cupcakes.

This means that she knows the exact amount she spent on cookies and in total so now to find out how much she spent on cupcakes, she subtracts $36.44 from $102.44($66) and then divides 66 by 11(6). So if you needed the problem solved x=6.

Lenox ironed of the shirts over the weekend. She plans to split the remainder of the work equally over the next 5 evenings. If Lenox has 40 shirts, how many shirts will she need to iron on Thursday and Friday? Do not include units in your answer.

Answers

Answer: 16

Step-by-step explanation:

Total shirts = 40

Number of evenings = 5

If we split the remainder of the work equally over the next 5 evenings.

then, the number of shirts she will need to iron on each evening = [tex]\dfrac{40}{5}=8[/tex]

Number of shirts need to buy on Thursday and Friday = 2 (8) = 16

Hence, the number of shirts she need to iron on Thursday and Friday = 16

Elena goes for a long walk. This graph shows her time and distance traveled throughout the walk.







What was her fastest speed, in miles per hour?



Do not include units (miles per hour) in your answer.

Answers

Answer:

Actually it is 4 mph.

Step-by-step explanation:

I know because I had it on a test I just took.

Her fastest speed was 4 miles per hour.

Given that,

Elena goes for a long walk.

This graph shows her time and distance traveled throughout the walk.

We have to find,

What was her fastest speed, in miles per hour?

According to the question,

The graph shows the time and distance traveled throughout the walk.

The distance traveled in every hour is given as follows.

In the given graph at the first point, the distance traveled in 1 hour is 3 miles.

At the second point, the distance traveled in 1.5 hours is 0 miles.

At the third point, the distance traveled in 2 hours is 5 miles.

At the fourth point, the distance traveled in 3 hours is 7 miles.

At the fifth point, the distance traveled in 4 hours is 9 miles.

Therefore, Her fastest speed was 4 miles per hour.

Jaden places potatoes with a mass of 0.55 kilograms on a grocer's scale. The spring is displaced by 1.2 centimeters. He then places some onions on the scale that displace the spring by 0.67 cm. What is the mass of the onions (1 kg=9.8 N)? 5.39 kg 3.01 kg 0.67 kg 0.31 kg

Answers

Answer:

.31 kg

Step-by-step explanation:

F=kx

F = the force of the spring

k = the spring constant

x = the spring displacement (stretch or compression)

we also know that 1 kg = 9.8 N which also means that 9.8(kg)=F

let's first find the force of the first problem, which is .55 kg. Using the formula 9.8(kg)=F we can do 9.8(.55)=F which would mean the force is 5.39 N

so 5.39=k(1.2 centimeters)

Now we need to convert centimeters to meters. This would make 1.2 into .012m. Now our problem is 5.39=k(.012)

divide 5.39 by .012 to get 449.17

our k is 449.17

Now for our problem, we are going to find the mass.  

Do this by putting what we already know into the problem.

F=449.17(.67 centimeters)

Now we already know we need to convert centimeters to meters which will make our formula F=449.17(.0067m)

This will result in F=3.01 but the problem is asking for mass, not force.

Use the formula 9.8(kg)=F

9.8(kg)=3.01

kg=.31

solution: .31 kg

If there are 48 boys and 60 girls in a room, fill out all of the possible ratios of boys to girls that could be made.

Answers

Hi! Hope this helps & if so, be sure to Mark Brainly!

Okay, so first let's lay out some info first to make things easier:


48 students total in the school play
Ratio of boys to girls is 5:7
How many more girls are there than boys in the play?


Let's let "5x" represent the number of boys in the school play and "7x" represent the number of girls in the school play.


5x = boys

7x = girls


If we know that the total number of students in the play equals 48, then that must me that both the number of boys and girls combined must equal 48:


5x + 7x = 48

12x = 48

x = 4


Now, take your x-value and plug it into both the boys' and girls' values to figure out how many boys and girls there are in the play:


5x = 5 (4) = 20 boys

7x = 7 (4) = 28 girls


To find out how many more girls there are than boys in the play, just subtract the number of girls minus the number of boys:


# girls - # boys = 28 - 20 = 8


This means that there are 8 more girls than boys in the school play.
