which of the following is the ratio of boys to girls in tamir's math class?
12/27
12/15
15/12
27/12

Answer:

Your pay rate is:  

$ 7  per hour

Your friend's pay rate is  :

$ 9  per hour

Explanation:

So if it takes you  8  hours to make  $ 56 , you can just divide the total money earned by the time.  So it would be  56 ÷ 8  which is  7 .

And if takes your friend  4  hours to make  $ 36 , you can divide like we just did . So it would be  36 ÷ 4  which is  9 .

So you make  $ 7  per hour and your friend makes  $ 9 per hour.

#5 = car cuz at first it was stationary(was at the garage) then the owner left to buy some snacks so he took the car and accelerated(the graph was steep) after some time he was going at constant speed. When he found MacDonalds he decelerated and parked his car

#8

a)it shows the no. of people joining the school

b)No. it wouldnt make sense to connect the dots cuz one pont isn't related to the other. For instance today a the joker killed 15 people and the next day he kills 16 people. You cannot say that he kills 15.5 people daily.

c) no. of puppies born

The resulting equation after substitution is

5x + 4(-2x + 6) = 3

quite literally you replaced y with what it equals (as said in the second equation)

you then distribute the 4 within the parenthesis

5x + -8x + 24 = 3

You make it easier

5x - 8x +24  = 3

you combine like terms

-3x + 24 = 3

you subtract 24 from both sides

-3x = -21

you divide both sides by -3

meaning x = 7

you then use that value x = 7 and substitude it for the x in the other equation.

That makes the y equation

y = -2(7) + 6

you then solve

y = -14+6

y = 6 - 14

y = -8

Answer: -1/x3y

(negative 1 over x to the third y)

Step-by-step explanation:

1) I simplified on the bottom

2) I combined like terms with y and x

3) then I just divided

4) then just combine the x and y and that's how I got this answer

Answer:

1/2 or 2

Step-by-step explanation:

If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.

The scale factor of the dilation is 1/2.

Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given:

Before dilation

AC= 8, BC= 10 abd AB= 6

After dilation

AC= 4, BC= 5 and AB= 3

Now, scale factor

Scale factor = Dimensions of the new shape / Dimensions of the original shape.

So,

scale factor = 4/8  or 5/10  or  3/6 = 1/2

Hence, the scale factor is 1/2.

Answer:

62 weeks

Step-by-step explanation:

What we need is to represent the ratios in expression

For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is

992-5x

x is the weeks

And the other case the expressions is

1240-9x

The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount

992-5x=y

1240-9x=y

in both the y is the same, then

992-5x=1240-9x

992-1240=-9x+5x

-248=-4x

-248/-4=x

62=X

and that is the weeks we need for the amount being the same in both tanks
