The expression 2T+3F+4M+10E

gives the number of points a student earns on a test when the student correctly answers T true-false questions, F fill-in-the-blank questions, M multiple-choice questions, and E extended-response questions. Which statement is NOT true?

Given:

Total number of students at Colfax Middle School = 270

Ratio of boys to girls is 5:4.

Total number of students at Winthrop Middle School = 180

Ratio of boys to girls is 4:5.

The two schools hold a dance and all students from both schools attend.

To find:

The fraction of the students at the dance are girls

Solution:

There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4.

[tex]5+4=9[/tex]

Number of boys [tex]=270\times \dfrac{5}{9}=150[/tex]

Number of girls [tex]=270\times \dfrac{4}{9}=120[/tex]

There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5.

[tex]4+5=9[/tex]

Number of boys [tex]=180\times \dfrac{4}{9}=80[/tex]

Number of girls [tex]=180\times \dfrac{5}{9}=100[/tex]

Now,

Total number of students in both schools [tex]= 270+180[/tex]

                                                                [tex]= 450[/tex]

Total number of girls in both schools [tex]= 120+100[/tex]

                                                         [tex]= 220[/tex]

The fraction of the students at the dance are girls is

[tex]\text{Required fraction}=\dfrac{\text{Total number of girls in both schools}}{\text{Total number of students in both schools}}[/tex]

[tex]\text{Required fraction}=\dfrac{220}{450}[/tex]

[tex]\text{Required fraction}=\dfrac{22}{45}[/tex]

Therefore, the required fraction is [tex]\dfrac{22}{45}[/tex].                                

470 = 29x+35

(x is number of birthday cakes)

subtract 35 from both sides,

435 = 29x

divide both sides by 29 to get x by itself,

15 = x

15 birthday cakes were made!

Answer:

35+29x=470 x=15 cakes

Step-by-step explanation:

3 35 represents rate for the oven and then 29 dollars per cake is the 29. 470 is the total amount of money you spent you just have to solve the equation from then to get x equals 15

The right equation of the red line will be f(x)=y-4 if the equation of the black line is f(x)=y

The equation is like a relationship between variables.

A variable is anything which have a value.

If we see the points of red line and the lack line we can see the value of x in black line is 4 greater than red line so the equation will be

f(x)=y-4 for the red line for the given equation of the lack line which is f(x)=y

A caucluation he can use is adding, just add 7422 and  5570 and you should get your answer.

Step-by-step explanation:

Mario walked total 12992 steps.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Mario walked 7422 steps one day

and, he walks 5570 stops the next day.

So, the total number of steps

= 7422 + 5570

= 12992 steps

Hence, Mario walked total 12992 steps.

Complete Question

Alisa hopes to play beach volleyball in the Olympics someday. She has convinced her parents to allow her

to set up a beach volleyball court in their back yard. A standard beach volleyball court is approximately

26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand.

Sand A = 60Ibs = $5

Sand B = 150lbs = $12

Alisa uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Choose one of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Identify which brand was chosen as part of your answer.. Answer:

For Sand A should would need:

$11.266.67

Step-by-step explanation:

From the above question, we can assume that: her court is 1 cubic foot and can be filled with 100 pounds of sand

First we find the volume of the box

52ft × 26ft × 1 ft

= 1352 ft³

100Ib = 1 ft³

1352 ft³ × 100 Ib/ft³

= 135200Ibs

Sand A = 60Ibs = $5

Hence, $1 = 60Ibs/5

= 12Ibs

To purchase enough sand using Sand A to fill the court

= 135200Ibs/12lbs

= $11.266.67

Answer: 594 and 30888

Step-by-step explanation:

5400 x 0.11 = 594

594 dollars in commission of one week

52 weeks in a year

52 x 594 = 30888 dollars made in 2011

594 dollars in commission of one week.

$30888 he make in commission in​ 2011.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Stocks sold= $5400

Commission each week = 11%

So, Commission on Stocks sold

= 5400 x 0.11

= 594

Thus, 594 dollars in commission of one week.

As, 1 Year = 52 weeks

So, He can make in 2011 = 52 x 594 = $30888

Answer:

The answer would be y=-5/3x-5!

Step-by-step explanation:

You want to make the equation to y=mx+b, so you have to make y by its self. Subtract 5x from both sides and you'll get 3y=-5x-15. Now divide 3 by both sides and you'll get y=-5/3x-5 which would be the answer!

Answer:

y=(-5/3)x-5

Step-by-step explanation:

so the slope intersect form is y=mx+b

3y+5x=-15

subtract 5x from both sides

3y= -5x-15

divide both sides by 3

y= (-5/3)x - 5

$1,050*125x=P(x). I just need more characters.

Step-by-step explanation:

The equation that represents Arnold's total monthly paycheck is

P(x) = 125x + 1050.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, Each month, Arnold receives $1,050 for working part-time at his uncle's camera store so it is a constant income.

For each camera that he sells, he earns a $125 bonus.

Let P(x) be the monthly check and no. of cameras sold be x.

∴  Arnold's total monthly paycheck P(x) selling x cameras is,

P(x) = 125x + 1050.
