Answers

Answer:

6 / 2/3 = 9

Step-by-step explanation:

Carrie want to find out the number of towels that will fit each row along the back of the shower

The back of the shower measures 6 ft long

Each towel is 2/3 foot long

Therefore the equation which shows how to determine the number of tile that will fit in each row is

Since 1 tile is 2/3 foot long then the number the number of tile in each row is

= 6 / 2/3

Answers

Answer:

Both of these equations are in slope-intercept form. The slope-intercept form of a linear equation is: y=mx+b

Where m is the y-intercept value.

y=-2x+5

y=-2x+20

The slope of the two equations are: m1=−2 and m2=−2

Step-by-step explanation:

Because the have the same slope it means the lines represented by these two equations are either parallel or are the same line.

The y-intercepts for the two lines are:b1 = 5 and b1=20

About how many times as large is Jupiter's mass compared to Earth's mass? Justify your answer.

Answers

Answer:

Earth is 85.71 times heavier than moonJupiter is 333.33 times heavier than Earth

Step-by-step explanation:

Given

The mass of Earth is about 6 x 10^24 kilograms = eThe mass of the moon is about 7 x 10^ 22 kilograms = mThe mass of Jupiter is about 2 x 10^27 kilograms = j

The difference in mass

e/m = 6 x 10^24 / 7 x 10^ 22 = 600/7 = 85.71

Earth is 85.71 times heavier than moon

j/e = 2 x 10^27 / 6 x 10^24 = 2000/6 = 333.33

Jupiter is 333.33 times heavier than Earth

Answers

Answer:

73 degrees

Step-by-step explanation:

So first, since there are two lines that are parallel, and there is a transversal, angle a and angle b are supplementary due to same side interior angles.

Next, we make an equation: 6x-35+3x+53=180, and after that you come up with 9x+18=180. Put the numbers on one side and the variables on one side, and since you put 18 on the other side, you have to change it to -18. 180-18= 162.

9x=162. In conclusion, x=18. And to find angle a, plug x in. Therefore, the final answer is 73 degrees

Keiko purchased a prepaid phone card for $20 . Long distance calls cost 16 cents a minute using this card. Keiko used her card only once to make a long distance call. If the remaining credit on her card is $17.28 , how many minutes did her call last?

Answers

Answer:

17 minutes

Step-by-step explanation:

To answer this question, all we have to do is subtract the original amount of money on the phone card by what is remaining after Keiko's call:

20 - 17.28 = 2.72

Now, we divide this number by 0.16:

2.72 / 0.16 = 17

So, Keiko's call lasted 17 minutes

Which statements about experimental probability are true? Select three options.

A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.
B: Experimental probability is the same as theoretical probability.
C: An experiment to determine probability will include a number of trials.
D: A probability experiment will count the number of times an event occurs.
E: Experimental probability can be written in the form of a ratio.

Answers

Answer:

I don't know this exactly, but I'll give it my best go!

We can get the answer by answering questions we know are true and eliminating the ones we don't.

E: Experimental probability can be written in the form of a ratio.

- Any probability can be expressed by a ratio so this is true.

B: Experimental probability is the same as theoretical probability.

- They are two different 'types' of probability so this is most likely false.

A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.

- I'm fairly certain that applies to theoretical probability, not experimental.

So that means the answers are most likely C, D, and E. If I was wrong let me know!

Find the value of x for which p || q.

Answers

Answer:

x = 9

Step-by-step explanation:

For the lines to be parallel, then

9x + 8 and 15x - 46 are alternate angles and congruent, thus

15x - 46 = 9x + 8 ( subtract 9x from both sides )

6x - 46 = 8 ( add 46 to both sides )

6x = 54 ( divide both sides by 6 )

x = 9

Answer:

The process is ; We can do by ; The two angles are alternate angles ( Z) . So, ( 9x+8) = ( 15x-46). OR, 9x+8=

In Aunt Peggy’s backyard there are cows and chickens. There are 20 more chickens than cows. The total number of legs is 130. How many chickens and how many cows are there? (Each cow has 4 legs, each chicken has 2 legs.) PLZ HELP! Will mark brainliest

Answers

Answer:

There are 15 cows and 35 chickens

Step-by-step explanation:

So first you take 20 and multiply it by two since there are two legs on each chicken. You get 40.

Then you subtract 40 from 130. You get 90.

Since the cow has double the legs of the chicken, you can count the cow as two chicken.

You divide 90 by 3. You get 30.

To get the number of chicken you divide 30 by 2 and you get 15.

You add 15 and 20 together and you get 35 chickens.

To get the number of cows you divide 30 by 2 and you get 15.

So you have your answer. 35 chicken and 15 cows.

The vertex of this parabola is at (-1,-3). Which of the following could be its equation?

A. x=-2(y + 1)2-3
B. x=-2(y-1)2-3
C. x= -2(y + 3)2-1
D. x = -2(y-3)2-1

Answers

Answer:

NONE

The vertex form of an equation of the parabola with vertex (-1,-3) is:

y = a(x + 1)² - 3

where a could be any number, also -2,

Step-by-step explanation:

The vertex form of an equation of the parabola:

y = a(x - h)² + k

vertex is (-1, -3) so h = -1, k = -3

so:

y = a(x - (-1))² + (-3)

y = a(x + 1)² - 3
