Not Sure How To Do This Can You Help Me ?

Answers

Answer 1

Here , we are going to use Trigonometric ratios.

In given right angled ∆ ;

[tex]{:\implies \quad \sf \dfrac{x}{18}=\sin (60^{\circ}) \quad \bigg\{ \because \sin (\theta)=\dfrac{P}{H}\bigg\}}[/tex]

[tex]{:\implies \quad \sf x=\dfrac{18\sqrt{3}}{2} \quad \bigg\{\because \sin (60^{\circ})=\dfrac{\sqrt{3}}{2}\bigg\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad x=9\sqrt{3} \: units}[/tex]

Also;

[tex]{:\implies \quad \sf \dfrac{y}{18}=\cos (60^{\circ}) \quad \bigg\{ \because \cos (\theta)=\dfrac{B}{H}\bigg\}}[/tex]

[tex]{:\implies \quad \sf x=\dfrac{18}{2} \quad \bigg\{\because \cos (60^{\circ})=\dfrac{1}{2}\bigg\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad y=9 \: units}[/tex]

Hence , The required values for x and y are 9√3 and 9 units

A dealer sold 200 tennis racquets. Some were sold at $18 each and others were sold at $33 each. The total sales were 4,800. How many of each priced racquet was sold?
Explain your answer.

Answers

Let x = number that sell for $18 each
Then, 200 - x = number that sell for $33 each

18x + 33(200 - x) = 4800

18x + 6600 - 33x = 4800

-15x = -1800

x = 120

There were 120 racquets selling for $18 each and 80 racquets selling for $33 each.

The mean of 16 items was found to be 30. On rechecking, it was found that two items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Find the correct mean. Round to the nearest Hundredth.

Answers

Answer: The answer is 31.25 because The mean of 16 items was found to be 30. So once you checked, it was that 2 items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Sum = mean  no of items = 30  16 = 480

(32 +28) – (22 + 18) = 20

Correct mean =  = 31.25

Onur is participating in a walkathon fundraiser. Two donors promised to donate money based on the total distance he walks. The money, A, in dollars, that he receives from the first donor given that he walks d kilometers is given by the formula A(d)=10d. The money, B, in dollars, that he receives from the second donor given that he walks d kilometers is given by the formula B(d)=2d+d^2.

Let T be the total money that Onur raises from those donors by walking d kilometers in the walkathon.

Write a formula for T(d), in terms of A(d) and B(d).
T(d)= ?

Write a formula for T(d), terms of d.
T(d)=?

Answers

Answer:

1. T(d) = A(d) + B(d)

2. T(d) = 12d + d²

Step-by-step explanation:

From the question given above, the following data were obtained:

A(d) = 10d

B(d) = 2d + d²

1. Determination of the formula of T(d) in terms of A(d) and B(d).

T(d) is the total money obtained. Thus,

T(d) = A(d) + B(d)

2. Determination of the formula of T(d) in terms of d.

A(d) = 10d

B(d) = 2d + d²

T(d) =?

T(d) = A(d) + B(d)

T(d) = 10d + 2d + d²

T(d) = 12d + d²

A university has three table tennis scholarships each worth $1000. How many ways are there to award these after they've narrowed
the candidates to 6 ping pong players?
Blank 1:

Answers

Answer:

1. In the presence of restrictions; A player cannot win more than one scholarship;

The number of ways is 120 ways

2. In the absence of restrictions; A player can win more than 1:

The number of ways is 216 ways

Step-by-step explanation:

Here, to award the scholarships, the restrictions we might have is that a student cannot win more than 1 scholarship

Given this restriction;

The first scholarship has 6 possible contenders

The second has 5

The third has 4

So, the number of possible ways is;

6 * 5 * 4 = 120 ways

In the absence of no restrictions where a student can win any number of scholarships;

We have the 3 scholarships being awarded in 6 possible ways

So the total number of ways will be;

6 * 6 * 6 = 216 ways
