Answer:

There are 6 fiction books in the bin. The probability of randomly selecting a fiction book from the bin is 0.6 or 3/5.

Step-by-step explanation:

The third bullet point says that the probability of selecting a poetry book is 1/5, and the second point says that the probability of selecting a fiction book is three times as likely than the poetry books.  So that would mean we must multiply 1/5 by 3. So do that you could turn it into a decimal first. 1/5 as a decimal is 0.2. Next, we multiply it. So 0.2 times 3 equals 0.6. Therefore the answer is 0.6. And to convert that back to a fraction, it would be 3/5.

Answer:

the tree is 30 ft tall

Step-by-step explanation:

27/x = 4.5/5

cross multiply

(4.5)(x) = (27)(5)

4.5x = 135

divide the entire equation by 4.5 to isolate x

135/4.5 = 30

x = 30

Answer:

30ft

Step-by-step explanation:

Proportion/ratio question

Tree : Your friend

27ft  :   4.5ft

?      :   5ft

Formula given divided by the original or missing value equivalent

g/o = 5/4.5 = 1.11111 multiplier

Then use multiplier for the tree given value.

27 x 1.111111 = 29.999997

= 30ft

Answer:

x<4

Step-by-step explanation:

The graph is not ending therefore X can be only lower than 4. -4 wouldn't be considered to be in the answer as it is a value of x itself. Also, X can't be greater than 4 because 4 is the starting point of the graph. So the X is always lower than 4 and can equal -4. So it would be x<4.

Answer:

(1200-650)/25=22

Step-by-step explanation:

1200-650=550

25x_=550 or 550/25=_

They need to sell 550 before he restocks

(1200-650)/25=22

I think lol

Answer:

just as you can add the same value to each side of an equation without changing the meaning of the equation, you can subtract the same value from each side of an equation.

by-step explanation:

x+7=42

Since 7 is being added to the variable, subtract 7 to isolate the variable.

To keep the equation balanced, subtract 7 from both sides of the equation.

x+7=42

-7 over x+0

-7 over 35

so answer is 35

The random number list shows that it will take at least 5 kid's meals to collect all three toys.

Answer:

D. 600 [tex]cm^{2}[/tex]

Step-by-step explanation:

Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]

So, the side length is 10 cm

Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length

so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]

6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]

So the answer is D. 600 cm (it should have a little superscript 2 next to it)

Answer:

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]

so we can write i as

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

By cross multiplication

y=4x

So, if write it in the form y=kx,

It will be y=4x.

Answer:

I think D but I'm not 100 percent certain

Answer:

B. 4 ft

Step-by-step explanation:

First, find the width of the wall.

The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.

Use the pythagorean theorem and solve for a, the width of the wall.

a² + b² = c²

a² + 16² = 20²

a² + 256 = 400

a² = 144

a = 12

So, the width of the wall is 12 feet.

Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.

Use the pythagorean theorem again and solve for a, the width of the mural:

a² + b² = c²

a² + 6² = 10²

a² + 36 = 100

a² = 64

a = 8

So, the width of the mural is 8 feet.

Now, find the difference between the widths of the wall and mural:

12 - 8

= 4

So, the difference between the two widths is B. 4 ft

Answer:

mario paid 15,000$ for his car

Answer: $15,000

Step-by-step explanation:

This is basic proportions.

We are given that 9000=60%

Therfore 100%=X.

Using the formula of proportions, we can calculate (9000*100)/60

This gives up 15000

Therfore he paid $15,000 for his car, which is 100% of the price.

https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/cc-8th-graphing-prop-rel/v/graphing-proportional-relationships-example

Step-by-step explanation:

Answer:

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.
