Answer:

[tex]v = u + at \\ v = 3 + (1.5 \times 7) \\ v = 3 +10.5 \\ \boxed{v = 13.5 \: m {s}^{ - 1}} [/tex]

Answer:

B) 4

Step-by-step explanation:

Use the slope formula:

slope [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (1 , -2)\\(x_2 , y_2) = (2 , 2)\\[/tex]

Plug in the corresponding numbers to the corresponding variables:

slope:

[tex]m = \frac{2 - (-2)}{2 - 1} \\m = \frac{2 + 2}{2 - 1}\\m = \frac{4}{1} = 4[/tex]

B) 4 is your answer.

Answer:

Tax would be 4500$

Step-by-step explanation:

15/100 = x/30000

Do 15 x 30000 = 450000

then divide 450000 by 100 = 4500

Answer:

Total area = 232.5 m²

Total cost to paint the area = £139.5

Step-by-step explanation:

Area of the composite figure = Area of trapezoid A + Area of rectangle B +                  Area of trapezoid C

Area of trapezoid A = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and h is the distance between them.

Area of A = [tex]\frac{1}{2}(8+10)4[/tex]

                = 36 square meter

Area of rectangle B = Length × width

                                 = 12 × 10

                                 = 120 m²

Area of trapezoid C = [tex]\frac{1}{2}(10+7)(9)[/tex]

                                 = 76.5 m²

Therefore, area of the composite figure = 36 + 120 + 76.5

                                                                   = 232.50 m²

Cost of paint = £6 for a tin that covers 10 m²

Therefore, total cost to paint the given figure = [tex]\frac{6}{10}\times 232.5[/tex]

                                                                            = £139.5

Answer:

62.5% of the parking spaces are taken.

Step-by-step explanation:

Given

To determine

What percent of the parking  spaces are taken?

The percentage of taken spaces of the part can be determined using the formula

% of Taken spaces = [Taken spaces / Total Spaces ] × 100

                               = [1875 / 3000] × 100

                               = 0.625 × 100

                               = 62.5%

Therefore, 62.5% of the parking spaces are taken.

If rectangular field has an area of 646 square feet. The width of the field is 19 feet. Then length of the field is 71.77 feet.

The area of Rectangle is length times of width.

Given,

Area of rectangular field is  646 square feet.

width of the field is 19 feet.

We need to find the length of the field.

Area of rectangle=Length×Width

646=Length×19

Divide both sides by 19

Length=646/9

Length=71.77 feet

Hence 71.77 feet is the length of the field.

Step-by-step explanation:

use the following equation

aₙ=a₁+(n-1)d

Where d is the common difference

n is the term

a₁ is the first term

the common difference is -3 (149-152)

this means we have

Step-by-step explanation:

Answer:  12.6 ft

Step-by-step explanation:

a = 8.8 ft

b = 9 ft

c = ?

Since it is a right triangle, we can use the Pythagorean Theorem to solve for missing side c, the hypotenuse.

a^2 + b^2 = c^2

(8.8)^2 + (9)^2 = c^2

158.44 = c^2

(158.44)^(1/2) = c

12.5873 = c

c = 12.6 ft (rounded to the nearest tenth)

Answer:

30%

Step-by-step explanation:

Selma spent 3/10 of her allowance on a new backpack.

Hence, the percent of her allowance that she spent is calculated as:

Fraction of allowance spent on Backpack × 100

= 3/10 × 100

= 0.3/1 × 100

= 30%

Therefore, Selma spent 30% of her allowance on a new backpack.

Answer:

QR = 4x - 6

Step-by-step explanation:

A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.

The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.

From the question:

Perimeter of triangle PQR = PQ + PR + QR

But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.

Therefore substituting gives:

8x - 6 = (x + 1) + (3x - 1) + QR

8x - 6 = (x + 3x + 1 - 1) + QR

8x - 6 = 4x + QR

QR = (8x - 6) - 4x

QR = 4x - 6
