Answer: [tex]\frac{27}{48}[/tex]

The ratio of motor homes to travel trailers in three different ways can be written as 27 : 48, 9 : 16 and 18 : 32.

Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.

The ratio of a and b is denoted as a : b.

Given that,

Number of travel trailers that Renae saw = 48

Number of motor homes she saw = 27

We have to find their ratio.

Ratio of motor homes to travel trailers = 27 / 48

Both are multiples of 3. So we can simplify this.

Ratio of motor homes to travel trailers = 9/16

Multiplying numerator and denominator with 2,

Ratio of motor homes to travel trailers = 18/32

Hence the ratio can be 27 : 48, 9 : 16 and 18 : 32.

Answer:

0.22

Step-by-step explanation:

The numbers that would be greater than 78 would include numbers after 78. that is 79, 80 ... 100

The total numbers greater than 78 is 22.

And there are 100 numbers in the bag . the probability of picking a number greater than 78 is 22/100 = 0.22

128 feet of lumber

Step-by-step explanation:

In order to fence a garden, the rowan family needs 64 feet of lumber. The garden at the correas house will need to be 100% larger. How man feet of lumber will the correas need?

Step 1

We calculate how many feet larger

Hence:

64 × 100%

= 64 feet

Step 2

How many feet of lumber will the correas need:

= 64 feet + 64 feet

= 128 feet

Answer:

Step-by-step explanation:

Slope is equal to the change in  y  over the change in  x , or rise over run.

m = change in y /change in x

The change in  x  is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise).

m = y 2 − y 1/ x 2 − x 1

Substitute in the values of  x  and  y  into the equation to find the slope.

m = 8 − ( 0 ) /3 − ( 1 )

Simplify.

Simplify the numerator.

m = 8 /3 − ( 1 )

Simplify the denominator.

Multiply  − 1  by  1

m = 8 /3 − 1

Subtract  1  from  3

m = 8/2

= 4

The probability of selecting a consonant is 0.619

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

The phrase is = "Terrace Park Wolves rule"

The number of letters in the phrase = 21 letters

The number of consonants in the phrase = 13 letters

Now ,

The probability of choosing a consonant from the given set of letters =
number of letters in the phrase / number of consonants in the phrase

Probability of choosing a consonant from the given set of letters = 13 / 21

Probability of choosing a consonant from the given set of letters = 0.619

Hence , The probability of selecting a consonant is 0.619

I'm not sure, but it might be A

Step-by-step explanation:

Vertex is 1375. The other person said it was B, but someone else said it can't be that. The foci is (7356471.694,0) (-7356471.694,0), so can't be that. Guessing, don't take my word for it unless this gets a high rating

The possible location of the sound source with 1375 feet apart. Then the correct option is A.

The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.

A pair of listening posts picks up a sound, with one listening post recording the sound after the other.

The equation will be

[tex]\rm \dfrac{x^2}{1890625 }- \dfrac{y^2 }{ 7,109,375}=1[/tex]

The equation represents possible locations of the sound source with units in feet.

The equation can be written as

[tex]\rm \dfrac{x^2}{1375^2}- \dfrac{y^2 }{ 2666.34^2}=1[/tex]

The listening posts are 1375 feet apart.
