<span>Just in case you didn't understand them :)

So we start off by breaking it down!!
3:4, 3+4=7 

In other words (or any at that lol) we find out that 280 can be broken off into 3 parts!

3 part=3/7×280  = 120
giving us 120 as the end result! 

</span><span>We also find out that 280 can be broken off into 4 parts!
</span><span>
4 part =4/7×280=160
Leaving us with 160

Meaning that now, we put the two new found ratios together to create our answer!! :)

So, 3:4 now equals 120:160

So your answer will be 120:160

</span> I hope this helps, I know that it helps for me when someone breaks it down for me! :)

vlada-n [284]

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Step-by-step explanation:

We have to calculate his unit rate for both type of races

So,

<u>Unit rate for 400m race:</u>

Distance = 400m

Time = 43 sec

Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second

<u>Unit rate for 300m Race:</u>

Distance = 300m

Time = 31 sec

Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second

The difference between both unit rates is:

U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec

Hence,

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Rotating the shown triangle so the square is at a bottom corner the height is 6 and the base is 6

Area = 1/2 x 6 x 6 = 18 square cm

Which of the following sets of values correctly completes the T chart for the equation Y =|3x+1|. -5,1,7
Ivahew [28]

Option C:

5, 1, 7

Solution:

Given equation:

y = |3x + 1|

In the chart, x values are given as –2, 0, 2.

To find the value of y for the corresponding x given.

Substitute x  = –2 in the equation of y.

y = |3(–2) + 1|

  = |–6 + 1|

  = |–5|   (Absolute value of a negative number is positive)

y = 5

Substitute x  = 0 in the equation of y.

y = |3(0) + 1|

  = |0 + 1|

  = |1|

y = 1

Substitute x  = 2 in the equation of y.

y = |3(2) + 1|

  = |6 + 1|

  = |7|   (Absolute value of a negative number is positive)

y = 7

Option C is the correct answer.

The values of y are 5, 1, 7.
