The <em><u>correct answer</u></em> is:

B) x = 12  

Explanation:

Problem number 26 states "Find a quantity such that when it is added to ¼ of itself the result is 15. "

Algebraically, this is represented as

x + ¼x = 15

Adding these together, we would have 1 ¼x = 15.

To write this as an improper fraction, we remember that 1 = 4/4; this gives us

4/4x + ¼x = 15

5/4x = 15

Divide both sides by 5/4:

(5/4x)÷(5/4) = 15÷(5/4)

x = 15÷5/4 = (15/1)÷(5/4)

To divide fractions, we flip the second one and multiply:

x = (15/1)×(4/5)

Multiplying fractions means we multiply the numerators and multiply the denominators:

x = (15×4)/(1×5) = 60/5 = 12

d1i1m1o1n [39]

Answer: A.4Runner cost more for $11.02

              B.Cost of fuel for Elentra: 3.75*3.59=$13.46

                 Cost of fuel for 4Runner : 6.818*3.59=$24.48

Step-by-step explanation:

A.Find how many gallons 4Runner spends on 150 mile trip.

use proportion

22:1=150:x

22x=150

x=150/22

x=6.818 gallons  

Cost of fuel for 4Runner : 6.818*3.59=$24.48

Calculation for Elentra:

40:1=150:x

40x=150

x=150/40

x=3.75 gallons

Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02

4Runner cost more for $11.02

B.Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fuel for 4Runner : 6.818*3.59=$24.48

The area of the entire figure below is 111 square unit.
sergeinik [125]

Based on the calculations, we can describe the area of the striped rectangle as 4/10 × 2/3.

<h3>What is a rectangle?</h3>

A rectangle can be defined as a type of quadrilateral in which its opposite sides are equal and all the angles formed are right angle.

<h3>How to calculate the area of a rectangle?</h3>

Mathematically, the area of a rectangle can be calculated by using this formula;

A = LW

<u>Where:</u>

  • A represents the area of a rectangle.
  • l represents the length of a rectangle.
  • w represents the width of a rectangle.

<u>Given the following data:</u>

Width = 3 rectangles (top to bottom).

Length = 10 rectangles (left to right).

Substituting the given parameters into the formula, we have;

Area = 10 × 3

Area = 30 rectangles.

From the diagram (see attachment), we can logically deduce that the striped rectangle comprises 8 rectangles, and the required area is given by:

Area of striped rectangle = 8/20 of the other portions

Area of striped rectangle = 8/20 × 20/30

Area of striped rectangle = 4/10 × 2/3.

A box is shaped like an octagonal prism. Here is what the base of the prism looks like. If the height of the box is 7 inches, th
Monica [59]

Answer:

The volume of the box is 33.796 cubic inches

Step-by-step explanation:

Given

Height = 7in

See attachment for the base of the prism

Required

The volume of the box

From the attachment, we have:

a = 1in -- side length of the octagon

The area is then calculated as:

Area = 2 * (1 + \sqrt 2)a^2

So, we have:

Area = 2 * (1 + \sqrt 2)* 1^2

Area = 2 * (1 + \sqrt 2)* 1

Area = 2 * (1 + \sqrt 2)

Evaluate the square root

Area = 2 * (1 + 1.414)

Area = 2 * (2.414)

Area = 4.828

The volume is then calculated as:

Volume = Height * Base\ Area

Volume = 7 * 4.828

Volume = 33.796
