→Answer:

(1,0)

→Step-by-step explanation:

Well first we need to graph the following equation.

$y=-5x^2+8x-3$ , look at the image below.

So if one x intercept is at (.6,0) then looking at the graph we can see the other one is at (1,0).

5.2 x 10^3 + 7 x10^4 =__ x 10_ Write your final answer in scientific notation

andreev551 [17]

The scientific notation of the given number is 7.2× $10^{4}$ .

<h3>How do you find scientific notation?</h3>

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

Given that,

$2$ × $10^{3}+7$ × $10^{4}$

Taking the common power of 10.

= $10^{3}$ × (2+70)

= 72× $10^{3}$

In scientific notation,

Multiply and divide by 10.

7.2× $10^{4}$

Hence, The scientific notation of the given number is 7.2× $10^{4}$ .

$115, 370, 250, 93, 540, 225, 177, 425, 318, 182, 275, and\ 228.$

find:

Sample mean=?

$=\frac{\text{total dental expenses}}{number \ of \ employees}$

$=\frac{115+370+250+93+540+ 225+ 177+ 425+ 318+ 182+ 275+228}{12}\\\\=\frac{3,198}{12}\\\\=266.5\\\\$

Three pipes A, B and C take 24, 36 and 32 hours to fill a pool, respectively. How long would it take the three pipes to fill the

Murrr4er [49]

Answer:

12 hours

Step-by-step explanation:

Time taken by pipe A = 24 hours

Time taken by pipe B = 36 hours

Time taken by pipe C = 32 hours

To find:

How long would it take the three pipes to fill the pool if pipe B is turned on 3 hours after pipe A and pipe C is turned on 1 hour after pipe B?

Solution:

First of all, let us assume the total capacity of the pool.

Let us take LCM of 24, 36 and 32.

LCM of 24, 36 and 32 = 288

Let the total capacity of the pool = 288 units

Total units filled by pipe A in one hour = $\frac{288}{24} = 12\ units$

Total units filled by pipe B in one hour = $\frac{288}{36} = 8\ units$

Total units filled by pipe C in one hour = $\frac{288}{32} = 9\ units$

Now, for the first 3 hours, only pipe A operates, so units filled in first three hours = $12\times 3 =36\ units$

For the next one hour, A and B both operate together, so units filled in the next 1 hour = 12 + 8 = 20 units

Total number of units filled in 4 hours = 36 + 20 = 56 units

Units to be filled to completely fill the pool = 288 - 56 = 232 units

Now, after the 4th hours, all the pipes operate together.

So, number of units filled in each hour = 12 + 8 + 9 = 29 units

Time taken to fill 232 units = $\frac{232}{29} = 8\ hours$

Total time taken = 4 + 8 = <em>12 hours</em>
