Answer:

Step-by-step explanation:

So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540

Then it is algebra

540=91+125+92+(3x-5)+(4x-8)

Simplify what you can and collect like terms

540=308+3x-5+4x-8

540=308+7x-13

Then move everything over to the one side so that the variable is isolated

540-308+13=7x

245=7x

242/7=x

35=x

The cost of one pair of earing will be £8.59.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given that four friends, each bought matching necklaces and two pairs of earrings the necklace was priced at 15.00 if the total bill for all 4 friends was 128.00.

The cost of one pair of earing will be,

£128-£15-£15-£15-£15= £68

Number of pairs of earing,

2x4=8 pairs of earrings

The cost of one pair of earrings is,

£68 / 8 = £8.50

Therefore, the cost of one pair of earing will be £8.59.

Explanation:

The diagram shows us we have this data set

{5, 8, 8, 8, 8, 9, 9, 9, 10, 10}

Cross off the outer most items (the 5 and the second 10) to get this smaller set

{8, 8, 8, 8, 9, 9, 9, 10}

Repeat the last step of crossing off the outer most items to get

{8, 8, 8, 9, 9, 9}

Keep this process going until we have this set of steps

{8, 8, 9, 9}

{8, 9}

We have two items left, which are tied for the middle, so we compute the midpoint

(8+9)/2 = 17/2 = 8.5 is the median

This is the middle most value

The ages of the Stars are the most dispersed from the team’s mean

Standard deviation is one way to measure the average of the data by determining the spread of the data. It actually explains how much the observation points are further away from the mean of the data.

Higher the standard deviation, higher the spread of the data and higher is the uncertainty. This means that the team with the highest standard deviation will have the most dispersion.

In this case, the standard deviation of 4.1 is the largest number, therefore, the statement "The ages of the Stars are the most dispersed from the team’s mean." is true

The material needed to make the tent assumes the shape of a triangular prism and the surface area of the material needed is 193.18 ft².

A triangular prism is indeed a three-sided prism made up of a triangle base, a translational copy, and triple faces connecting equivalent sides in geometry.

The properties of a triangular prism include:

Let's assume that the shape of the canvas tents is in form of a triangular prism, to determine the material needed to make the tent, we need to understand the surface area of a triangular prism.

However, let's assume that:

From the image attached below: the surface area of the triangular prism can be calculated by using the following  formula:

[tex]\mathbf{A = 2A_B +(a+b+c)h }[/tex]

[tex]\mathbf{A_B = \sqrt{s(s-a)(s-b)(s-c)}}[/tex]

[tex]\mathbf{s = \dfrac{a+b+c}{2}}[/tex]

Combining the formulas together the surface area of the triangular prism can be computed as:
[tex]\mathbf{S.A = ah+bh+ch+\dfrac{1}{2} \sqrt{ -a^4+2(ab)^2+2(ac)^2-b^4 +2(bc)^2-c^4}}[/tex]

[tex]\mathbf{S.A = (6\times9)+(6\times9)+(6\times9)+\dfrac{1}{2} \sqrt{ -6^4+2(6 \times 6)^2+2(6 \times 6)^2-6^4 +2(6 \times 6)^2-6^4}}[/tex]

S.A = 193.18 ft²

Rent = 720 dollars / month

Step-by-step explanation:

Remark

You can afford to pay out 30% of your take home pay for rent.

Givens

Take home pay: 2400 dollars.

Rent alotment: 30%

Rent:x

Formula

rent = % of pay * Take home pay

Solution

x = 30/100 * 2400            Divide by 100

x = 0.30 * 2400                Multiply the right

x = 720

Answer:

26

Step-by-step explanation:

For a centroid there is a 2:1 ratio for AG:GF and for BG:GD. Because BG is 40, GD is 20, so x is 2. Using that information, you can solve for AG. 19(2)+14, which is 52. This means that GF is 52/2 = 26.

Answer:

6

Step-by-step explanation:

Using sine rule, the value of x in the triangle formed by five roads is 53.36 degrees.

The value of x can be found using sine rule.

Therefore,

73.2 / sin 37°  = 97.6 / sin x

cross multiply

73.2 sin x = 97.6 sin 37°

73.2 sin x  = 97.6 × 0.60181502315

73.2 sin x  = 58.7371462596

divide both sides by 73.2

sin x = 58.7371462596 / 73.2

x = sin⁻¹ 0.80242003086

x = 53.3618236772

x = 53.36°

Therefore, the value of x is 53.36°
