There are 60 students eating lunch in the cafeteria five-tenths of them brought lunches from home. How many students brought lunches from home?

Answer:

17.75

Step-by-step explanation:

So what we know is that we have to DIVIDE the bill evenly by the amount of people sharing the bill.

> 53.25 / 3 = ?

> 5 - 3 = 2 ( one 3 goes into 5 )

> 23 - 21 = 2 ( seven 3s goes into 23 )

> 22 - 21 = 1 ( seven 3s goes into 22 )

> 15 - 15 = 0 ( five 3s goes into 15 evenly )

> 53.25 / 3 = 17.75

So this should be your result afterwards.

there is 114 in there

Answer:

17

Step-by-step explanation:

Answer:

The hypotenuse is 17.

Step-by-step explanation:

a^2+b^2=c^2.

Let's plug in a and b.

15^2 + 8^2 = c^2

Simply.

225+64=c^2

Add.

289=c^2.

Square 289 and c^2 to cancel out the ^2.

17=c

The hypotenuse is 17.

No equation really.

I guess she could just by 2 lb green grapes and 3 lb red grapes.

Maybe because I didn't understand the question completely.

Step-by-step explanation:

such an equation is a simple linear function :

y = ax + b

b is in this case the flat fee, and a (the slope) drives the incline of the function for various numbers of students x.

our job is now to find the correct a and b values.

we do this by using the informative we have and create 2 equations for a and b, and then we solve this system.

132.5 = a×25 + b

145 = a×30 + b

now, we can use a little trick and simply subtract the whole first equation from the second equation.

145 = a×30 + b

- 132.5 = a×25 + b

------------------------------

12.5 = a×5 + 0

5a = 12.5

a = 2.5

with this we go into one of the original equations, e.g. the second one :

145 = 2.5×30 + b = 75 + b

70 = b

so, it full equation is

y = 2.5x + 70

the costs for 85 students are

y = 2.5×85 + 70 = 212.5 + 70 = $282.50

Answer:

12 books

Step-by-step explanation:

25% is the same as 1/4

3=25%=1/4

if you multiply 3 by 4 you get 100% or 12

You can also do this by adding 9, aka 3*3, to 3 to get 3*4=12.

Answer:

its F for the inequality to be true

Answer:

10

Step-by-step explanation:

2 → $3500

? → $17500

? = 17500 x 2 / 3500 = 3500/3500 = 10

OR

3500 → 2

3500/2 = 1750

17500/1750 = 10

Therefore, whatever method you use, you will get 10 as an answer.

Step-by-step explanation:

honestly it depends on the question but if it's addition, this is the answer

ok its either D or B but i think its D. Most likely.

Answer:

ok so first you do this 25.75 + 6.20 = 31.95 and then you just do like this 53.65 - 31.95 = 21.7 that would be the answer and the answer is 21.7

Answer:

About $4.98

Step-by-step explanation:

The cost of 30 ounces of iced tea will be $4.98.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

18 ounces. of iced tea costs 2.99. Then the ratio of cost to weight is calculated as,

⇒ $2.99 / 18

⇒ $0.166 per ounce

Then the cost of 30 will be calculated as,

⇒ $0.166 x 30

⇒ $4.98

The cost of 30 ounces of iced tea will be $4.98.

Answer:

J' (- 10, - 8 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

J (10, - 8 ) → J' (- 10, - 8 )

Answer:

(-10, -8)

Step-by-step explanation:

The rule for a reflection over the y -axis is (x, y)→(−x, y) .

so J(10, -8) becomes J'(-10, -8)

The amount spent on each tube is $18.5

The total amount spent to rent 15 tubes by the group is $277.50.

Since they did not specify in the question the types of tubes they rented, we cannot determine each types of tubes that the group rented but we can determine the amount spent on each tube provided that they are all the same types.

∴

if 15 tubes = $277.50

1 tube = $x

By cross multiplying:

[tex]\mathbf {\$(x) = \dfrac{ \$277.50 \times 1 \ tube }{15 \ tube}}[/tex]

[tex]\mathbf {(x) = \$18.5}[/tex]

Therefore, we can conclude that the amount spent on each tube is $18.5

The value of x is 11.

The equations with one, zero, or an infinite number of solutions are known as linear equations with two variables. Each of the two variables in these equations has the largest exponent order of 1. A two-variable linear equation has the conventional form axe + by + c = 0, where x and y are the two variables. The answers can also be expressed as ordered pairs, such as (x, y). Two straight lines, which could be intersecting, parallel, or coincident, are included in the graphic representation of the system of linear equations in two variables.

Given equations

5x + 2y =  67

x = 3y - 7

substitute the value of x in equation 1

5(3y - 7) + 2y = 67

15y - 35 + 2y = 67

17y = 67 + 35

17y = 102

y = 6

and x = 3y - 7

x = 3(6) - 7

x = 18 - 7

x = 11

Hence value is 11.
