18x45=810

Answer:B

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

Formula to be used,

Scale factor = [tex]\frac{\text{Dimension of the image rectangle}}{\text{Dimension of the original}}[/tex]

By this formula,

[tex]\frac{7}{2}=\frac{\text{Length of the dilated rectangle}}{\text{Length of the original rectangle}}[/tex]

[tex]\frac{7}{2}=\frac{L}{22}[/tex]

L = [tex]\frac{7\times 22}{2}[/tex]

  = 77 inches

Similarly, width of the the dilated rectangle = [tex]\frac{7}{2}\times 10[/tex]

                                                                        = 35 inches

Perimeter of the new rectangle = 2(Length + width)

                                                    = 2(77 + 35)

                                                    = 224 inches

Option (D) will be the correct option.

Answer:

In statistics, scientists or researchers gather data to represent the existing number of population audience that they should target. Statisticians usually lump these data and present them in terms of mean, median or mode. To be more accurate, percentage could also be used. Percentage is generally defined as the number of a specific parameter per 100 units of the whole. In this case, the percentage is defined as the number of students per 100 people of the whole population. The working equation to be used is:

Percentage = Number of Students/Number of Population * 100%

Percentage = 9,860/62,400 * 100

Percentage = 15.8%

Hence, out of the total population, 15.8% are students.

or

Number of students = 9860

Total Population = 62,400

Percentage of students in the population can be calculated by:

(Number of students/Total population) x 100%

Using the values, we get:

Percentage of students = (9860/62400) x 100% = 15.80%

Thus, students constitute 15.80% of the entire population

Answer:

Guarantee of Tyre = 36,680 miles

Step-by-step explanation:

Given:

Mean = 46,000 miles

Standard deviation = 4,000 miles

Computation:

Assume;

x = guaranteed lifetime

P(X > x) = 99%

So,

P(X > x) = 0.99

So,

P(Z > z) = 0.99

So,

1 - P(Z > z )  = P(Z < z)

P(Z < z) = 0.01

So, in z table value of z = -2.33

x = μ + [z x σ]

x = 46,000 + [-2.33 x 4000]

x = 36,680

Guarantee of Tyre = 36,680 miles

Answer:

60ft

Step-by-step explanation:

        multiple the length by 2

15 times two equals 30

       multiple the width by two

15 times two equals 30

       add the total lengths and widths

30 plus 30 equals 60

ans=60

Answer:

The surface area of the rectangular prism is 17.5

Step-by-step explanation:

We are given:

Width of rectangular prism (w) = 0.5

Length of rectangular prism (l) = 1.5

Height of rectangular prism (h) = 4

We need to find the surface area of the rectangular prism.

The formula used is: [tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)[/tex]

Putting values and finding the surface area of the rectangular prism

[tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)\\Surface \ area \ of \ the \ rectangular \ prism=2((1.5)(0.5)+(1.5)(4)+(0.5)(4))\\Surface \ area \ of \ the \ rectangular \ prism=2(0.75+6+2)\\Surface \ area \ of \ the \ rectangular \ prism=2(8.75)\\Surface \ area \ of \ the \ rectangular \ prism=17.5[/tex]

So, the surface area of the rectangular prism is 17.5
