12 m Fence 17 m 20 m one can of weedkiller can cover 100 square metres. eachh can costs $19.75 work out the total cost of the cans of weedkiller needed to cover the lawn.

Answers

Answer 1

Answer:

Total amount needed is: $59.25

Step-by-step explanation:

Given

See attachment for fence

Required

Cost of weedkiller needed

First, we need to calculate the height of the fence.

Considering the triangular end of the fence, we have:

[tex]17 ^ 2 = h ^ 2 + 8 ^ 2[/tex] --- Pythagoras theorem

[tex]289 = h^2 + 64[/tex]

Collect like terms

[tex]h ^ 2 = 289 - 64[/tex]

[tex]h ^ 2 = 225[/tex]

Take positive square root of both sides

[tex]h = \sqrt{225[/tex]

[tex]h = 15[/tex]

Next, calculate the area of the fence (trapezium).

This is calculated as:

[tex]Area = \frac{1}{2}(a + b) * h[/tex]

Where:

[tex]a = 12[/tex]

[tex]b = 20 + 8 = 28[/tex]

So, we have:

[tex]Area = \frac{1}{2}(12 + 28) * 15[/tex]

[tex]Area = \frac{1}{2}(40) * 15[/tex]

[tex]Area = 20 * 15[/tex]

[tex]Area = 300m^2[/tex]

From the question, we have:

[tex]\$19.75 = 100m^2[/tex]

Let x = the cost required for the complete area

i.e.

[tex]x = 300m^2[/tex]

So, we have:

[tex]\$19.75 = 100m^2[/tex]

[tex]x = 300m^2[/tex]

Cross multiply

[tex]x * 100m^2 = \$19.75 * 300m^2[/tex]

Divide both sides by [tex]100m^2[/tex]

[tex]\frac{x * 100m^2}{100m^2} = \frac{\$19.75 * 300m^2}{100m^2}[/tex]

[tex]x = \frac{\$19.75 * 300m^2}{100m^2}[/tex]

[tex]x = \$19.75 * 3[/tex]

[tex]x = \$59.25[/tex]

b Pete won the first heat in 13 minutes 39 seconds. Jacob won the second heat in 14 minutes 16 seconds. Who ran faster? By how much? t​

Answers

In accordance with the research problem we were given, Pete outran Jacob by 37 seconds.

A second of angle is what?

Minutes are the 60 equal pieces that make up each degree. Thus, 7 to 8 inches can also be written as seven degrees and thirty minutes, or seven°30'. For example, 2 ° 5 minutes and 30 seconds are represented by the notation 2° 5' 30 since each minutes is further subdivided into 60 equal seconds.

Then, we have Pete's time: First, we convert minutes into seconds. 13 minutes and 39 seconds is equal to 13 * 60 + 39, or 819 seconds.

Jacob's period: 14 minutes and 16 sec. = 14 * 60 + 16 sec. = 856 sec.

Jacob outpaced Pete by 856 – 819 = 37 seconds.

Pete ran 37 seconds faster as a result.

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given data ,

Let the mixed number equation be represented as A

Now , the value of A is

To solve each equation, we can convert mixed numbers to improper fractions, then multiply the fractions, and simplify the result if possible.

A)

A = 5/6 × 4 2/3 = (5/6) × (4×3 + 2)/3

A = (5/6) × 14/3 = 35/9, which is not equal to 3 8/9.

Therefore, equation A is false.

B)

B = 1 1/10 × 8 3/5 = (11/10) × (43/5)

B = 473/50 = 9 23/50, which is not equal to 9 1/2.

Therefore, equation B is false.

C)

C = 3 2/9 × 2 1/6 = (29/9) × (13/6)

C = 377/54 = 6 53/54

Therefore, equation C is true.

D)

D = 2 3/7 × 1 7/8 = (17/7) × (15/8)

D = 255/56 = 4 23/56 = 2 3/8

Therefore, equation D is true.

E)

E = 7/12 × 4 = 7/3 = 2 1/3

Therefore, equation E is true.

Hence , the equations that are true are C, D, and E

Answers

Given:

Initial value of the stock = $100

Growth factor = 1.5 each week.

To find:

The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.

Solution:

Let V be the current value of the stock after t week.

The exponential growth model is:

[tex]V=ab^t[/tex]

Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.

Substituting [tex]a=100,b=1.5[/tex], we get

Anita needs to construct ten cones for a class project. How many square feet of material will she need? Use 3.14 for π. Enter your answer in the box. Th radius is 6 ft and the height is 12 ft.

Answers

Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√ (h²+r²), where r is the radius and h is the height.

r = 6 ft / 2 = 3 ft

Solving for the lateral surface area of one cone:

LSA = (3.14) (3) [√ (12²+3²) ] = 116.52 sq ft.

Since she needs 10 cones:

10 * 116.52 sq. ft = 1,165.2 sq ft.

She will need 1,165.2 sq ft of material.

PQ and QR are 2 sides of a regular 12-sided polygon.
PR is a diagonal of the polygon.

Work out the size of angle PRQ.
You must show your working.

Answers

The size of the angle m∠PRQ for the polygon is equal to 15°

How to calculate for the angle PQR using interior angle of the polygon

To calculate the sum of interior angles of a polygon, you can use the following formula:

Sum of interior angles = (n-2) x 180 degrees

Where "n" represents the number of sides (or vertices) of the polygon.

Given the 12 sided polygon;

(12 - 2) × 180 = 1800

one interior angle = 1800/12 = 150°

The angle PQR is a base angle of the Isosceles triangle ∆PQR with one interior angle of the 12-sided polygon so;

m∠PRQ = (180 - 150)/2

m∠PRQ = 15°.

Therefore, the size of the angle m∠PRQ for the polygon is equal to 15°

Answers

Given:

The area of the squares are given.

To find:

The exact side length or estimate side length of the square.

Solution:

We know that, the area of a square is

[tex]A=a^2[/tex]

Where, a is the side length of the square.

[tex]a=\sqrt{A}[/tex]

Area of the square is 100 square units. So, the side length is:

[tex]a=\sqrt{100}[/tex]

[tex]a=10[/tex]

Therefore, the side length is 10 units.

Area of the square is 95 square units. So, the side length is:

[tex]a=\sqrt{95}[/tex]

It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].

Therefore, the side length is between 9 and 10.

Area of the square is 36 square units. So, the side length is:

[tex]a=\sqrt{36}[/tex]

[tex]a=6[/tex]

Therefore, the side length is 6 units.

Area of the square is 30 square units. So, the side length is:

[tex]a=\sqrt{30}[/tex]

It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].

Therefore, the side length is between 5 and 6.
