sladkih [1.3K]1 year ago
8 0

Step-by-step explanation:

  • in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
  • If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
  • Now let us plug in the value of x=-3
  • y =  - 3( - 3) + 7 \\ y =  - 9 + 7 \\ y =  - 2
  • now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
  • therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.

Uniforms are sold in packages of 8. The stores 127 employees will each be given 3 uniforms. How many packages will the store nee
Kruka [31]
Ok so
represent number of packages as n
so the total number of uniforms is
(number of uniforms per package) times n aka
8 times n aka
8n

127 employees
each person needs at least 3, therefor
127 times 3=381
they need at least 381
therefor
8n<u>></u>381
divide both sides by 8
n<u>></u>47.625
you can't order a decimal box so you round up so you don't have too less
47.625 goes to 48

Pete, Chris, and Dina realized that the number of A’s they each received on their report cards were in a ratio of 4:2:5. If Pete
Fiesta28 [93]

Answer:

A's received by Dina is 35.

Step-by-step explanation:

Given

number of A’s  received  by Pete, Chris, and Dina on their report cards were in a ratio of 4:2:5.

Let the

A's received by Pete = 4x

A's received by Chris = 2x

A's received by Dina = 5x

This, is done so that ratio of 4:2:5 remains intact.

Now, given  Pete got 14 more A’s than Chris got

Thus, writing it mathematically

A's got by Pete = A's got be Chris + 14

we will be using A's got Pete and Chris in term of x as defined above

4x = 2x+ 14

=> 4x - 2x = 14

=> 2x = 14

=> x = 14/2 = 7

A's received by Dina = 5x = 5*7 = 35( Answer).

the water pipe has a radius of 5 cm and a height of 7 cm. What volume of water does it take to fill the pipe
kvv77 [185]
When you're looking for the volume of a cylinder, you have to use the equation V=  \pi r^{2} h
And this V is equal to volume, R is equal to radius, and H is equal to height.
In this case, you've got to find what r²is. To do this, square 5. 5x5= 25. 
You've then got to substitute this into the equation, along side H, which is equal to 7, and this gives you V=π*25*7, you've then got to multiply these all together (using π as 3.142) this gives you 549.85cm³
Therefore, you need 549.85cm³ of water to fill the pipe.
Hope this helps :)
