Answer:
Total students = 1240
Step-by-step explanation:
Boys : girls = 11 : 9
Number of boys = 11x
Number of girls = 9x
11x - 9x = 124
2x = 124
x = 124/2
x = 62
Number of boys = 11x = 11 *62 = 682
Number of girls = 9x = 9*62 = 558
Total students = 682 + 558 = 1240
What is a scale factor?
The ratio of weight of similar 2-D figures
The ratio of corresponding angles of similar figures
The ratio of corresponding sides of similar figures
The ratio of volume of similar 2-D figures
Answer:
Here is some helpful information from my mini lessons.
Step-by-step explanation:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.

Of the 520 students participating in a chess tournament, 35% were male. How many females were in the tournament?
Answer:
182
Step-by-step explanation:
take 520 and multiply by 0.35
The number of female students participated in a chess tournament is 338.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 520 students participating in a chess tournament, 35% were male.
Number of male students = 35% of 520
35/100 ×520
= 0.35×520
= 182
So, the number of female students
= 520-182
= 338
Therefore, the number of female students participated in a chess tournament is 338.

What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
All the graphs are examined one by one as follows,
(A) In the graph A, The slope is negative.
Which implies the the speed will slow down.
(B) In the graph B, The slope is positive.
Which implies the the speed will rise up.
(C) ) In the graph C, The slope is zero.
Which implies the the speed will be constant.
(D) In the graph D, The slope is positive and it has a y intercept.
Which implies the the speed will rise from a non zero value.
Thus, in order to download a large file the suitable graph is (B).
Hence, the given case can be represented by graph B.

wyatt opend a savings account 4 years ago. the account earns 4%interest compounded quarterly if the current balance is $1,000.00 how much did he deposit initially round your answer to the nearest cent
Answer:
He deposited initially $852.82
Step-by-step explanation:
The rule of the compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where
A is the new amountP is the initial amountr is the rate in decimaln is the period of the timet is the time∵ Wyatt opened a savings account 4 years ago
∴ t = 4
∵ The account earns 4% interest compounded quarterly
∴ r = 4% = 4 ÷ 100 = 0.04
∴ n = 4 ⇒ compounded quarterly
∵ The current balance is $1,000.00
∴ A = 1,000
→ Substitute these values in the rule above to find P
∵ 1,000 = [tex]P(1+\frac{0.04}{4})^{4(4)}[/tex]
∴ 1,000 = [tex]P(1+0.01)^{16}[/tex]
∴ 1,000 = [tex]P(1.01)^{16}[/tex]
→ Divide both sides by [tex](1.01)^{16}[/tex]
∴ 852.8212622 = P
→ Round it to the nearest cent (2d.p)
∴ P = 852.82
∴ He deposited initially $852.82

Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:

15) A car salesman earns $700 per week plus 2.5% commission on his sales. If he
sold two cars for a total of $75,000 last week, how much did he make?
Please help!
Answer:
$2575
Step-by-step explanation:
For this problem, we need to form an equation that represents the car salesman's weekly income. We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales. Let n represent the total amount of sales the car salesman made. So we can build the equation as follows:
f(n) = 0.025n + 700
Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.
So let's use our formula to calculate how much he made for the week given he made $75000 in sales.
f(75000) = 0.025(75000) + 700
f(75000) = 1875 + 700
f(75000) = 2575
Hence, the car salesman made $2575 for the week.

Dustin's Lawn Care Service Customer Amount Paid Mrs. Schmitt $15.75 Mr. Jones $9.25 Mrs. Adams $22.50 Mr. Meyer $50.00 How much more does Dustin get paid to mow Mr. Meyer's lawn than to mow the other three lawns combined? Enter your answer in the box. I need helppppp!
Answer: $2.50
Step-by-step explanation:
The following payments are made by Dustin's Lawn Care Service Customer
Mrs. Schmitt = $15.75
Mr. Jones = $9.25
Mrs. Adams = $22.50
Mr. Meyer = $50.00
To get our answer, we need to add all the payments of the other three. This will be:
= $15.75 + $9.25 + $22.50
= $47.50
The answer will now be:
= $50.0 - $47.5
= $2.50
