The length of a rectangle is 5 yd more than double the width, and the area of the of the rectangle is 42 yd to the second power
yanalaym [24]

Answer:

The answer to your question is l = 12 and w = 7/2 or 3.5

Step-by-step explanation:

Data

length = l

width = w

Area = 42 yd²

Process

1) Write equations that help to solve this problem

Area = length x width = l x w

Length = 2width + 5  or   l = 2w + 5

2) Substitution

                       42 = lw                               Equation l

                          l = 2w + 5                        Equation ll

                       42 = (2w + 5)w                   Substitute equation ll in l

3.- Expand

                       42 = 2w² + 5w

                       2w² + 5w - 42 = 0

Solve the equation by factoring

-Multiply 2 by 42

                             2 x 42 = 84

-Find the prime factors of 84

                         84 = 2² 3 7

-Find two numbers that added gives +5 using the prime factors

 These numbers are +12 and -7    

-Substitute the values in the equation

                         2w² -7w + 12w - 42

-Factor by grouping

                        w(2w - 7) + 6(2w - 7)                  

                           (2w - 7)(w + 6)

-Find w

                    2w₁ - 7 = 0             w₂ + 6 = 0

                      w₁ = 7/2               w₂ = -6   This value is discarted because

                                                                  there are no negative values

-Find l

                     l = 2(7/2) + 5

                     l = 7 + 5

                     l = 12

Static and Reasoning:
Serggg [28]

Based on the data recorded by Isabella, it can be concluded the cube is rather fair.

<h3>How many times did Isabella get each number?</h3>

Based on the data, here are the results:

  • Getting a 1: 6 times
  • Getting a 2: 5 times
  • Getting a 3: 7 times
  • Getting a 4: 5 times
  • Getting a 5: 6 times
  • Getting a 6: 7 times

This implies, in total Isabella got the same number between five and seven times. For example, the number 2 was obtained 5 times, but the number 3 was obtained 7 times.

<h3>What can be concluded based on the results?</h3>

Even though Isabella did not get the same number of times each number, the dice is rather fair because by rolling the dice thirty six times you will obtain the same number at least five times.

Moreover, there is not a big difference in the number of times you obtain each number.

Emma Punch with 3/4 gallons of pineapple juice 1 1/2 gallons of orange juice and 7/8 gallons of apple juice how much gallons of
Grace [21]

Answer:

<h2>7/8 gallons of Ginger ale </h2>

Step-by-step explanation:

Total gallons of punch mixture =  gallons of pineapple juice + orange juice + gallons of apple juice + gallons of Ginger ale

Given gallons of pineapple juice = 3/4 gallons

Orange juice = 1 1/2 gallons

Gallons of apple juice = 7/8

Total gallons of punch = 4 gallons

On substituting into the formula above:

4 = \frac{3}{4} +\frac{3}{2}+\frac{7}{8}+Gallons\ of\ ginger\ ale

4=\frac{6+12+7}{8} + Gallons\ of\ ginger\ ale]

gallons of ginger ale = 4-\frac{25}{8}

gallons ginger ale = \frac{7}{8}

She needs 7/8 gallons of Ginger ale to make the total of 4 gallons of punch
