Answer:

16 girls in the class

14 boys in the class

Step-by-step explanation:

Because of the ratio of 7:8, I added 7+8.

7+8= 15

30 (the number of students in the class) divided by 15 (the sum of the ratio)

30/15= 2

I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.

Hope this helps!

Answer:

-2⅓

Step-by-step explanation:

-4 + 5/3 Start out with this sum.

-4 + 1 ⅔ Make 5/3 into a mixed number.

-2 ⅓ Then add them together. The best way to do this is to first add -4 and 1 which makes -3. Then add ⅔ to -3 which is -2 ⅓

its subtracting 4 each time

Answer:

11:40 am

Step-by-step explanation:

First, I started by subtracting 5 minutes from the additional 25 minutes of running that couldn’t fit into another hour. That would bring the running time to 2 hours and 20 minutes and the end time to 2:00 pm. Take away another 2 hours and you would be left with 20 minutes, with a start time of 12:00 pm. Get rid of the last 20 minutes and you get the start time as 11:40 am.

Check:

11:40 + 2 hours = 1:40 pm

1:40 + 20 minutes = 2:00 pm

2:00 + 5 minutes = 2:05

This is correct

Answer:

Answer:

7/24

Step-by-step explanation:

The probability would be 28/96, but we can simplify this fraction:

Divide 2 on both sides:

14/48

Divide 2 again:

7/24

So 7/24 is your answer! :) I hope I helped!

Answer:

8.5 miles

Step-by-step explanation:

3x20=60, 60 minutes also being an hour so if you multiply 748 by 20 then it gives you 14,960 annndd now you have to divide by the amount of yards in a mile 14,960/1,760=8.5

Answer: brainly.... D. f(x) = 1.06x; $169.60

sales tax = 6% or 6/100.  

assuming tax is added onto the item:

total cost function f(x) = price + tax

however, assuming the cost price = sales price  - tax,  then:

f(x) = sales price - tax  

This is not really a business or accounting forum, its a maths forum, so you need to be clearer about business or accounting terms such as total cost, selling price, selling cost.

Step-by-step explanation: brainly

if y= the item after tax

y=x+(x*6%) or y=x+6%

and then for the answer you would go:

y=160+6% or 160+(160*6%)= $169.60

Answer: f(x)=1.06x; $169.60

Answer:

x = 9

Step-by-step explanation:

3 - √x = 0

Subtract 3 from both sides of the equation

3 - 3 - √x = 0 - 3

-√x = -3

Divide both sides by -1

-√x / -1 = -3 / -1

√x = 3

Take the square of both sides

(√x) ² = 3²

X = 9

Answer:

B, 8+12

Step-by-step explanation:

2 + 3 is 5, 4 × 5 = 20

Therefore the only option which equals 20 is B.

Complete question :

Write a system of equations, with one equation describing the cost to bowl at Bowl-o-Rama and the other describing the cost to bowl at Bowling Pinz. For each equation, let x represent the number of games played and let y represent the total cost.

Bowl-O-Rama rents shoes for $2 and each game cost $2.50

Bowling Pinz rents shoes for $4 and each game cost $2

Answer:

Bowl-O-Rama:

y = $2 + $2.50x

Bowling pinz:

y = $4 + $2x

Step-by-step explanation:

The total cost is the sum of shoe rental plus the product of the unit game rate and the number of games played.

Total cost, y

x = number of games played

Bowl-O-Rama:

y = Shoe rent + (unit rate per game * number of games)

y = $2 + ($2.50 * x)

y = $2 + $2.50x

Bowling Pinz :

y = Shoe rent + (unit rate per game * number of games)

y = $4 + ($2 * x)

y = $4 + $2x

Step-by-step explanation:

step 1. we will denote the average rate of change as r.

step 2. r = (f(5) - f(3))/(5 - 3)

step 3. r = (375 - 81)/2

step 4. r = 294/2

step 5. r = 147.

step 6. note: this is just like finding m. m = (y2 - y1)/(x2 - x1)

Step-by-step explanation:

...the population increased 5,9 x 10 6.

The ratio is 64:13

Ratio is the comparison of two quantities which is obtained by dividing the first quantity by the other. If a and b are two quantities of the same kind and with the same units, such that b is not equal to 0, then the quotient a/b is called the ratio between a and b. Ratios are expressed using the symbol of the colon (:). This means that ratio a/b has no unit and it can be written as a : b

Given data:

Population of china in 2005 =1.3*10^9

population of entire world in 2005 = 6.4*10^9

Now,

ratio= 6.4*10^9/ 1.3*10^9

ratio= 64/13 or 64:13
