Leslie ran 3 mile race. The second mile took her 10 percent longer than the first one and the third mile took her 24 seconds lon

Answer:

8.8 Minutes or 528 Second.

Step-by-step explanation:

↓[ Read Below ]↓

Important Info:

Leslie Ran 3 Mile Race.

2nd Mile = 10% longer than 1st and 3rd Miles took her 24s longer than 2nd Mile

Question to Answer:

Leslie’s total time for the race was 26 minutes how long did the second mile take her?

Explanation/Solution:

Let for first mile, she took x minutes . And second mile took her 10 percent longer, so second mile took

x+ 10/100x = 110/100x=1.1x

And the third mile took 24 seconds longer as compared to second mile .

So third mile took

1.1x+24/60 = (1.1x+0.4) Minutes

And the total time for the race was 26 minutes, that is

x+1.1x+1.1x+0.4=26

3.2x=26-0.4

3.2x=25.6

x= 25.6/3.2 = 8 Minutes

So the first mile took 8 minutes. And therefore second mile took

= 1.1 (8) = 8.8 Minutes

Also Equal to 528 Second.

You Create 15 Centerpieces In 5 Hours.How Long Will It Take To Make 42 Centerpieces
kogti [31]
If you are making 15 center pieces per hour, then you are making 3 per hour.
15/5 = 3
Then you divide how many centerpieces you are making by 3.

42/3 = 14

It will take you 14 hours to make 42.

Hope this helps!

Alisiya [41]
Answer: a

explanation: the vertical line test tests if the line is a function by stating that if it intersects the graph more than once it is not a function. if you drew a straight line through this line it would touch the graphed line twice, meaning it’s not a function.

The volume of a rectangular prism is (x4 + 4x3 + 3x2 + 8x + 4), and the area of its base is (x3 + 3x2 + 8). If the volume of a r
vfiekz [6]

Answer:

Height = x  \frac{x^3+3x^2+4}{x^3+3x^2+8}

Step-by-step explanation:

Volume = Base \ Area\ * Height

Height = \frac{Volume}{Base \ Area}

Where Volume = x^4+4x^3+8x+4 and Area = x^3+3x^2+8

Putting in the formula

Height = \frac{x^4 + 4x^3 + 3x^2 + 8x + 4}{x^3 + 3x^2 + 8}

Doing long division, we get

Height = x + \frac{x^3+3x^2+4}{x^3+3x^2+8}

Height = x  \frac{x^3+3x^2+4}{x^3+3x^2+8}

This is the simplifies form and it can't be further simplified.
