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.

compare and contrast between x-intercept and y-intercept

Answers

Answer:

"The x-intercept is the point at which the graph crosses the x-axis... ...The y-intercept is the point at which the graph crosses the y-axis." (Lumen)

The x-intercept is on the horizontal axis while the y-intercept is vertical axis. Aside from that they are practically the same and serve the same purpose while graphing, they just go in differing positions.

The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x-axis. ... The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero.

Is it possible to form a triangle using 15 in, 12 in, 8 in ? Why or why not?

Answers

Answer:

No

Step-by-step explanation:

Use the pythagoreon theory

15^2+12^2=8^2

454=64

Since they do not equal the same number you can not form a triangle, and no matter how many times you switch the numbers around they will not equal.

Carrie needs to determine the number of towels that will fit each row along the back of the shower if the back of the shower measures 6 feet long and each towel is 2/3 a foot long which equation shows how to determine the number of tiles that will fit in each row

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

= 6 ×3/2

= 18/2

= 9

How many unit cubes are required to create a larger cube with edge length of 3 units? Can I also get an explanation so I know how it's done? Thanks :)

Answers

Answer:

The unit cubes that are required to create a larger cube with an edge length of 3 units is:

27 cubes.

Step-by-step explanation:

To identify the number of cubes you need to create a larger cube, you must think in the number of cubes of the length (3 cubes in this case), and use the exponent 3, because you need to form a cube. Below I'll show you:

[tex]3^{3}= 27 cubes.[/tex]

To understand it in a better form, suppose that you need a cube with an edge of 5 units, in that case, remember you use the number 5 how base and the exponent is 3, because is a cube, in that case, it would be:

[tex]5^{3}= 125 cubes[/tex]

If it wasn't a cube but a square, you must elevate to the number 2, in the case of the cube is elevated to 3, so, the unit cubes that are required to create a larger cube with an edge length of 3 units is 27 cubes.

If you wanted to find the difference of 6/25-4/5,what common denominator should you choose?why?​

Answers

Answer:

25

Step-by-step explanation:

25 should be chosen as the common denominator. 5 is a possible common denominator because the other fraction has a denominator of 5 and 25 is divisible by 5, however, the numerator cannot be evenly divided by 5. Attempting to do so would cause a much more difficult equation. On the other hand, the denominator 5 can be changed to 25 by multiplying by 5, and 4 can also be changed by multiplying by 5.

4/5 x 5 = 20/25

6/25 - 20/25 = -14/20 = -7/10

Nolan gave out a survey to some students in his school about their favorite color. Students could choose between red and purple. 238 of those surveyed said their favorite color was red. 66% of the students surveyed said their favorite color was purple. How many students were surveyed in total?​

Answers

Answer:

700

Step-by-step explanation:

100%-66%=34%

34% equals the 238 that is red

238÷34%=7 people per percentage

7×66%= 462 students that chose purple

462+238=700 which should be the total amount of people surveyed.

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
