Answer:

<em>Correct choices: a) 5:12 and c) 7 to 12</em>

Step-by-step explanation:

The ratio of red beads to pink beads is 5:7. This means that for every 5 red beads there are 7 pink beads.

It also means that for every 12 beads there are 5 red beads and 7 pink beads.

Therefore, there are two part-to-whole ratios:

5:12 red beans to total beads, and

7:12 pink beans to total beads

Correct choices: a) 5:12 and c) 7 to 12

In a freefall skydive, a skydiver begins at an altitude of 10,000 feet. during a freefall, the skydiver drops toward earth towar
asambeis [7]

Answer:

{t|0\leq t\leq 50}

Step-by-step explanation:

We are given that

In a freefall skydive, a skydiver begins at an altitude during free fall =10,000 feet

The skydiver drops towards earth at a rate=175 ft/s

The height of the skydiver from the ground can be modeled using the function

H(t)=10000-175t

We have to find the domain of the function for this situation.

When t=0

Then ,H(0)=10,000 feet

From given graph we can see that the value of t  lies  from 0 to 50.

Therefore, the domain of the function for this situation is given by

{t|0\leq t\leq 50}

3x+4y=12 6x+2y=6 rewrite each equation and soap intercept form
miskamm [114]

  • Move 4y to the front so it should be 4y=12-3x
  • Divide the equation like how I did in the picture above then you should have y=3-3/4x
  • Then you switch it to y=-3/4x+3 and that's your answer.

Now for 6x+2y=6

  • Move 2y to the front so it looks like 2y=6-6x
  • Then you divide the equation by 2 like in the photo above and that should give you y=3-3x
  • Finally you switch the equation to y=-3x+3 because we are using the Slope Intercept Form. (Y=mx+b). That's your answer.

Sorry if my handwriting is bad.
