Step-by-step explanation:

The quadratic equation given to us is ,

→ 4v² + 6v - 88 = 0 .

So , wrt to standard form of a quadratic equation ax² + bx + c = 0 , the Zeroes are given by using the Quadratic formula as ,

⇒ x = -b ± √ ( b² - 4ac) / 2a

⇒ x = -6 ± √ [6² - 4 × 4 × (-88) ] / 2×4

⇒ x = -6 ± √ [ 36 + 1408 ] / 8

⇒ x = -6 ± √ 1444 / 8

⇒ x = -6 ± 38 / 8

⇒ x = -6 +38/ 8 , -6 -38 / 8

⇒ x = 32/8 , -44/8

⇒ x = 4 , -11/2

Here I took v as x . So we can replace it .

<h3><u>Hence </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>v</u><u> </u><u>is</u><u> </u><u>4</u><u> </u><u>,</u><u> </u><u>-</u><u>1</u><u>1</u><u>/</u><u>2</u><u> </u><u>.</u></h3>

The average of eight numbers is 56. When one of the numbers was left out, the mean decreased to 54. What number was left out?
Alexandra [31]

The number that was left out is 70.

<h3>What is the number that was left out?</h3>

Average is the sum of a set of numbers divided by the total numbers in the data set.

Average = sum of numbers / total numbers

  • Sum of numbers when there are 8 numbers = 56 x 8 = 448
  • Sum of numbers when there are 7 numbers = 54 x 7 = 378
  • Difference = 448 - 378 = 70

Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel. How long would i
Whitepunk [10]

Answer:

32 hours.

Step-by-step explanation:

Let x represent the time taken by Russell and Aaron to build the shed.

We have been given that Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel.

Russell's work rate would be \frac{1}{x}.

Since Aaron works three times as fast as Russel, so Aaron's work rate would be \frac{3}{x}.

Part of work done by in one hour would be \frac{1}{8}.

We can represent our given information in an equation as:

\frac{1}{x}+\frac{3}{x}=\frac{1}{8}

Let us solve for x.

\frac{1}{x}*8x+\frac{3}{x}*8x=\frac{1}{8}*8x

8+3*8=x

8+24=x

32=x

Therefore, it will take Russell 32 hours to build the shed working alone.
