What is the slope of the line? ​

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].                                

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 point (6,1) lies inside the circle.

Step-by-step explanation:

Equation of a Circle

A circle centered at the point (h,k) and with radius r, can be expressed with the equation:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

The center of the given circle is (0,0) and the radius is [tex]r=\sqrt{38}[/tex], thus the equation of the circle is:

[tex](x-0)^2+(y-0)^2=(\sqrt{38})^2[/tex]

Simplifying:

[tex]x^2+y^2=38[/tex]

Each point (x,y) meeting the condition of the equation lies exactly on its circumference. For example, the point [tex](\sqrt{2},6)[/tex] belongs to the circumference, but the origin (0,0) is inside the circle, and the point (5,5) is outside the circle.

We can tell the difference by evaluating the equation at each point. For the first point [tex](\sqrt{2},6)[/tex], the equation is:

[tex](\sqrt{2})^2+6^2=2+36=38[/tex]

The equation is satisfied.

For the origin (0,0):

[tex]0^2+0^2=0[/tex]

For the point (5,5):

[tex]5^2+5^2=50[/tex]

We can conclude that if the left side is greater than 38, the point is outside the circle, if it's less than 38, the point is inside the circle.

Let's test the point (6,1):

[tex]6^2+1^2=37[/tex]

The point (6,1) lies inside the circle.

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:

Answer in explanation

Step-by-step explanation:

The equation of a straight line can be represented in the form;

y = mx + c

where m is slope and c is y-intercept

In this particular case

y = 20x + 5

y is the weekly income, x is the number of lawns mowed

The y-intercept 5 is the amount earned in a week given they no lawn was mowed

In a case where y = 125

125 = 20x + 5

20x = 125-5

20x = 120

x = 120/20

x = 6

You need to mow 6 lawns to earn enough money in one week to buy the MP3 player
