Answer:

4

Step-by-step explanation:

Given that :

Total fraction of paint Carin has = 2/3 bottle

Fraction used to paint a model airplane = 1/6

Number of model. Airplanes 2/3 of a bottle could paint ;

Total fraction of paint / fraction used to paint a model airplane

(2/3) ÷ (1/6)

2/3 * 6/1

= 12 / 3

= 4 model airplanes

Answer:

[tex]y=\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]4(y+1)= \frac{3}{1-y}[/tex]

[tex]4y+4= \frac{3}{1-y}[/tex]

[tex](4y+4)(1-y)= 3[/tex]

[tex]4y(1-y)+4(1-y)=3[/tex]

[tex]4y-4y^{2} +4-4y=3[/tex]

[tex]-4y^{2}=3-4[/tex]

[tex]4y^{2}=1[/tex]

[tex]y^{2} = \frac{1}{4}[/tex]

[tex]y=\sqrt{\frac{1}{4} }[/tex]

[tex]y=\frac{1}{2}[/tex]

Answer:

the download cost for a song is $1 and $11 for a movie

Step-by-step explanation:

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence, the download cost for a song is $1 and $11 for a movie

This implies that only 90000 is divisible by 2

Answer:

false

Step-by-step explanation:

4(1) - 3(6)<12

4 - 18<12

12<12

so no the truth value is false 12 is not less than 12

Answer:

A. true

Step-by-step explanation:

If you plug in x and y, the equation is 4(1)-3(6)<12. SImplify to get 4-18<12 which is equal to -14<12 which is true.

Answer:

60

Step-by-step explanation:

The required number is 60.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now the given expression is,

4.5 is 7.5%

Let x be the number.

Therefore, 7.5% of x is 4.5

⇒ 7.5% of x = 4.5

⇒ 7.5% * x = 4.5

⇒ 7.5/100* x = 4.5

⇒0.075 x = 4.5

Dividing both side by 0.075 we get,

x = 4.5 / 0.075

Solving we get,

x = 60

this is the required number.

Thus,the required number is 60.

Answer:

Step-by-step explanation:

Hope this helps :D Hav a great day :P

Step-by-step explanation:

For every increase in the x-value by 1,

the y-value decreases by -2.

(From 3 to 1 and from 1 to -1)

Hence, slope of line k

= Rise/Run = (-2)/1 = -2. (A)

Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.

Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.

In this problem, two of the points are: (1,3) and (2,1).

Hence, applying the division:

[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]

The slope of the line is of -2, hence option A is correct.
