Good evening Gloria

3t(t+2)-3t² for t=19

Well the first thing we need to do is to replace 19 everywhere we see T

So let's do it together

3(19)(19+2)-3(19)²

57(21)-3(361)

1197-1083

= 114

I hope that's help and if you have questions please let me know :)


Please give my answer a Thanks and stars ↓

NO LINKS!!!<br><br>QRSTU ~ FGCDE. Find FG, CD, and EF. ​
arsen [322]

Answer:

See below ~

Step-by-step explanation:

Given :

<u>QRSTU ~ FGCDE</u>

Finding the scale factor :

  • Take two corresponding sides in proportion
  • RS : GC
  • 40 : 12
  • <u>10 : 3</u>

Applying the scale factor to find the missing sides :

- FG :

  • QR : FG = 10 : 3
  • 30/FG = 10/3
  • FG = 30/10 x  3
  • FG = 3 x 3
  • <u>FG = 9</u>

- CD :

  • ST : CD = 10 : 3
  • 40/CD = 10/3
  • CD = 40/10 x 3
  • CD = 4 x 3
  • <u>CD = 12</u>

- EF :

  • UQ : EF = 10 : 3
  • 30/EF = 10/3
  • EF = 30/10 x 3
  • EF = 3 x 3
  • <u>EF = 9</u>

Which explains why the graph is not a function?

The statements that apply to the ratio of rice and water are:

  • The ratio of rice to water is 1 to 2.5
  • The ratio of water to rice is 2.5 to 1

<h3>Ratios</h3>

Ratios are used to compare quantities of different measurements

The entries on the table are given as:

<u>Rice          Water</u>

2                  5

3                  7.5

5                 12.5

8                 20

<h3>The ratios of both quantities</h3>

The ratio (r) of rice and water is then calculated as:

r = \frac{Water}{Rice}

Pick any corresponding table entry.

So, we have:

r = \frac{5}{2}

Divide

r = 2.5

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1

Determine whether 5, 226 is divisible by 2,3,4,5,6,9, or 10.
uranmaximum [27]

Answer:

2,3,6

Step-by-step explanation:

5,226   ...(1)

unit digit=6

6 is divisible by 2,

so (1) is divisible by 2.

last two digits=26 ,not divisible by 4,

so (1) is not divisible by 4.

5+2+2+6=15 divisible by 3 but not divisible by 9.

so (1) is divisible by 3 but not divisible by 9.

2×3=6,so (1) is divisible by 6.

unit digit=6≠0 or 5

so (1) is not divisible by 5 or 10.
