Answer: 600

Step-by-step explanation:

Since there are 24% of boys in a school , this means that the number of girls will be :

100% - 24 %

= 76%

That means there are 76% of girls in the school.

Let the total number of students in the school be x, this means that

24% of x = number of boys

76% of x = number of girls

Since the total number of girls is given to be 456 , then

76% of x = 456

0.76x = 456

x = 456/0.76

x = 600

That means there are 600 students all together in the school

Answer:

600 students

Step-by-step explanation:

100% - 24% = 76%

76% = 456

100%= x

76x = 456x100

x = 45600÷76

x= 600 students (total)

Natali5045456 [20]

Answer:

$227

Step-by-step explanation:

First we can add up the withdrawals(63, 74, and 39) which is 176. We can then subtract 176 from 212 to get 36.

So, after the withdrawals Steven has 36 dollars.

We can add the deposits together to get 191. We can then add 191 to 36 to get 227.

A game costs $39.00. But the new special edition version is going to be $56.94. What is the increased percent?
astraxan [27]

Answer:

46%

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />39.00 * x = 56.94

39x = 56.94

<u>Step 2:  Divide both sides by 39</u>

<u />39x / 39 = 56.94 / 39

x = 1.46

<u>Step 3:  Find the percent</u>

<u />1.46 - 1 -> Gives us the increased percent

0.46 * 100

46%

Answer:  46%

timurjin [86]

Answer:

  • $10 per hour
  • 0.1 hours

Step-by-step explanation:

To find Carys' earnings in one hour, fill in h=1 in the formula:

  E = 10·1 = 10

Carys earns 10 dollars per hour.

__

To find the number of hours required to earn 1 dollar, fill in E=1 in the formula:

  1 = 10h

  0.1 = h . . . . . divide by 10

It takes 0.1 hours for Carys to earn 1 dollar.

The exponential model A = 661.7 e^0.011t describes the population, A, of a country in millions, t years after 2003. Use the mode
faust18 [17]

Answer:

661.7 million

Step-by-step explanation:

Given the exponential model :

A = 661.7 e^0.011t

The general form of an Exponential model is expresses as :

A = A0 * e^rt

Where A = final value ; A0 = Initial value ; r = growth rate and t = time elapsed

From the question t = time after 2003

Therefore, A0 = initial population, which is the population in 2003

Therefore, A0 = 661.7

Or we could put t = 0 in the equation and solve for A

A = 661.7 e^0.011(0)

A = 661.7 * 1

A = 661.7

Hence, population in 2003 is 661.7 million

Points A(-2, 4), B(1, 3), C(4, -1) and D form a parallelogram. What are the coordinates of D?
Rudik [331]
Let point A(-2,4)  = A (X1,Y1)
      point B( 1,3  )= B (X2,Y2)
      point C(4,-1)  = C (X3,Y3)
and point D(?, ?) = D (X4,Y4)  We have to find this point

To find X4 we have to use the formula:
X2-X1=X3-X4

Now just plug in the numbers that correspond to the letters provided:
(1)-(-2)=(4)-(X4) ----> we don't know what X4 is yet, so we have to solve for it!
1+2=4-X4
3=4-X4
3-4=-X4
-1=-X4  divide both sides by -1
X4=1

Now we have to find Y4 using this formula:
Y2-Y1=Y3-Y4

Therefore,
(3)-(4)=(-1)-(Y4)
-1=-1-Y4
-1+1=-Y4
0=-Y4
So,
Y4=0


Now we have found the coordinates of the point D, which is (1,0)

Hope this helped!
