Answer:

1/5 x (5m - 3) or 0.2 (5m -3)

Step-by-step explanation:

1. We convert 1 2/5 to 7/5 = 7/5m - 3/5 x (2/3 m + 1)

2. factor out 1/5 from the expression = 1/5 x (7m - 3(2/3m + 1))

3. Distribute -3 through the parentheses = 1/5 x (7m - 2m -3)

4. Collect like terms = 1/5 x (5m - 3)

leva [86]

I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337

Add this to 1 and we have 40.75093337

Then divide over 2pi to get a final approximate result of 6.48571248

So x = 6.48571248 is one approximate solution

In short, I computed \frac{1+\sqrt{1+160\pi^2}}{2\pi} only focusing on the plus for now.

----------------------

If you were to compute \frac{1-\sqrt{1+160\pi^2}}{2\pi} you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.

Anettt [7]
7/8 + 3/6 = 10/14 = 5/7 = 0.71 And if you want to make it a whole number, you multiply by 100 and you should get 71 as a whole number. Therefore: he can pour 71 gallon servings of bottled water. I hope this is helpful!!^_^!!

A fountain in the park has two circular pools that are the same size. What is the total area of the pools if the radius is 3 yar
mihalych1998 [28]

Answer:

56.6 square yards.

Step-by-step explanation:

Given:

A fountain in the park has two circular pools that are the same size.

<u>Question asked:</u>

What is the total area of the pools if the radius is 3 yards ?

<u>Solution:</u>

First of all we will calculate the area of a circular pool.

As we know:

Area\ of\ circle=\pi r^{2}

                       =\frac{22}{7} \times(3)^{2} \\ \\ =\frac{22}{7}\times9\\ \\ =\frac{198}{7} \\ \\ =28.28\ square\ yards

Area of circular pool nearest tenth = 28.3 square yards

Now, as given that both pools are of same size.

Total area of the pools = 28.3 square yards + 28.3 square yards

                                      = 56.6 square yards.

Thus, the total area of the pools are 56.6 square yards.

A time for the 100 meter sprint of 14.9 seconds at a school where the mean time for the 100 meter sprint is 17.6 seconds and the
kirza4 [7]

Answer:

Z-score = -1.285

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 17.6 seconds

Standard Deviation, σ = 2.1 seconds

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

For x = 14.9, we have:

z_{score} = \displaystyle\frac{14.9-17.6}{2.1} = -1.285

A z-score to be unusual if its z-score is less than -2.00 or greater than 2.00.

Thus, the z-score is not unusual as it lies in the range [-2.00, 2.00]
