There were 6 boys for every 9 girls at Winnsboro High School last year. If there were 480 students at the school, how many were girls and how many were boys?​

Answer:

6

Step-by-step explanation:

You have to separate the triangles into two, where you can compare short over long. DC = AB, so DC is the long side in the smaller triangle and AC is the shorter side. DC is similar to AC, and DE is similar to AB. Short over long side formula gives you [tex]\frac{x}{9} =\frac{4}{x}[/tex].

Cross multiply to get [tex]x^2=36[/tex]

Square root on both sides to get [tex]x=6[/tex]

Answer:

7 workers

Step-by-step explanation:

[tex]\frac{workers first time}{workers second time} = \frac{hours second time}{hours first time}[/tex]

[tex]\frac{3}{x} = \frac{12}{28}[/tex]

cross multiply and it becomes

12x = 3x28

12x = 84

x = 84/12

x = 7 workers

Answer

4

Step-by-step explanation:

3/28=x/12

that is 7 and you need to find how many more workers so you subtract

7-3=4

The amount of money Julie invested in the money market account at 5% interest is $600

According to the question;

x + y = 1500

4 × (0.025 × x) = (0.05 × y)

Therefore;

x = y/2

Therefore, y + y/2 = 1500

2.5y = 1500

y = $600

and

x = $900

Answer:

PQ = 18

Step-by-step explanation:

If R is the midpoint of PQ, then PR = RQ

⇒ 6x + 7 = 3x + 8

⇒ 3x = 1

⇒ x = 1/3

So PR = 6x + 7 = 6(1/3) + 7 = 9

and RQ = 3x + 8 = 3(1/3) + 8 = 9

⇒ PQ = PR + RQ = 9 + 9 = 18

Answer:

A. You need to draw a straight line that increases from left to right. Try and get the same amount of plots on the top and bottom of the line and go through one or two of the plots. Don't connect the dots, though.

B. This scatter plot demonstrates a positive association between a person's height and weight because the trendline increases from left to right. According to this data, as weight increases, so does height. The more someone weighs, the more likely they are to be tall.

Answer:

if the numbers were the same, they'd both be 61

So, try 60 and 62.

Algebraically, if x is the smaller number,

x + x+2 = 122

2x = 120

x = 60

By using distributive property of multiplication over subtraction we got 4 (5.97)  = 23.88 without actually multiplying 4 (5.97) .

This property states that when a number is multiplied by addition/subtraction of two number is same as multiplying this number with both the numbers individually and then adding/subtracting them.

let a, b, c are three numbers then distributive property of multiplication can be stated as :

a×(b ± c) =(a× b) ± (a ×c)

For Multiplying  4($5.97)

Write 5.97 = 6 -0.03

4 (5.97) =  4* ( 6 -0.03) = (4*6) -(4*0.03) (using distributive property)

⇒(4*6) -(4*0.03) = 24 - 0.12 = 23.88

Therefore without actually multiplying 4 (5.97)  we got 4 (5.97)  = 23.88 by using distributive property of multiplication over subtraction.

The balance in Adam's account at the end of June which has the credit card with an apr of 14.63% is $627.27.

Monthly payment is the payment which has to paid against the loan amount or the borrowed money calculated with interest rate.

The Adam’s credit card has an Apr of 14.63%,The table below shows his use of that credit card over three months.

For the purchase add the previous balance and for payment subtract the previous balance. I have mentioned another column for remaining balance in the above table.

The total of this transaction when multiplied with number of days, we get the total balance, 56498.48.

Now the monthly average balance is,

[tex]m=\dfrac{56498.48}{90}\\m=627.76[/tex]

Thus, the balance in Adam's account at the end of June which has the credit card with an Apr of 14.63% is near to $627.27.

Adam’s balance at the end of June is $629.42.

The adjusted balance method is an accounting method that bases finance charges on the amount(s) owed at the end of the current billing cycle after credits and payments post to the account.

Balance at the end of April = 626.45 + 37.41 + 44.50 = $708.36

Interest levied on $708.36= 708.36* (14.63/12) * 1/100

Interest levied on $708.36 = $8.64

So, balance on May 1st= 708.36+ 8.64 = $717

Balance at the end of May = 717-65.50+24.89-104.77 = $571.62

Interest levied on $571.62 = $571.62 * (14.63/12) * 1/100

Interest levied on  $571.62=$6.97

So, balance on June 1st = $578.59

Balance at the end of June = 578.59-23.60 + 15+51.85 = $621.84

Interest levied on $621.84 = $621.84* (14.63/12) * 1/100

Interest levied on $621.84 =$ 7.58

So balance at the end of the june = 621.84 + 7.58 = $629.42

Therefore, Adam’s balance at the end of June is $629.42.

Check the picture below.

since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.

[tex]\textit{arc's length}\\\\ s=\cfrac{r\pi \theta }{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=8\\ \theta =198 \end{cases}\implies s=\cfrac{(8)\pi (198)}{180}\implies s\approx 27.6[/tex]

700 x 10=7,000

7,000 x 10=70,000

Or another example take 8

8 x 10=80

8 x 100=800

8 x 1,000=8,000
