We can use the law of sines to solve this problem

sin A         sin B

---------  = ----------

a              b

sin 81        sin 40

Rounding to 1 decimal place

x = 10.8

Answer: 68.1

Step-by-step explanation:

The area of a semi-circle is 1/2 the area of a full circle. The area of a full circle is pi*r^2. Therefore, the area of a semi-circle is:

[tex]Area=\pi r^2/2[/tex]

[tex]Area=\pi (3)^2/2=9\pi /2[/tex]

The area of a rectangle is the length multiplied by the width:

As P varies directly as the product of I and V it is P = KVT

Proportions are of two types one is the direct proportion in which if a constant k increases one quantity the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if a constant k increases one quantity the quantity will decrease by the same constant k and vice versa.

Given, P varies directly as the product of I and V, therefore if P increases

V or I or V and I will also increase.

We can write this direct proportionality as,

P ∝ VI.

Now to remove the proportionality sign we'll use a constant factor K and an equality sign,

P = KVT.

The Margin of error is 0.3 when assuming a 90% confidence level.

It is given that among 320 randomly selected airline travelers, the mean number of hours spent traveling per year is 24 hours and the standard deviation is 2.9.

It is required to find the margin of error when the confidence level is 90%.

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

The formula for finding the MOE:

[tex]\rm MOE= Z_{score}\times\frac{s}{\sqrt{n}}[/tex]

Where  [tex]\rm Z_{score}[/tex] is the z score at the confidence interval

             s is the standard deviation

             n is the number of samples.

We have in the question:

[tex]\rm Z_{score}[/tex] at 90% confidence interval = 1.645 (From the Z score table)

s = 2.9

n = 320

Put the above values in the formula, we get:

[tex]\rm MOE= 1.645\times\frac{2.9}{\sqrt{320}}[/tex]

MOE = 0.2666

Rounding the nearest tenth:

MOE = 0.3

Thus, The Margin of error is 0.3 when assuming a 90% confidence level.

Answer:

294mm

Step-by-step explanation:

The surface area of each side is 7mm x 7mm. 7•7 = 49

There are 6 sides on a cube, so just multiply 49 times 6.

49•6= 294 mm

The value of sin c is 7/7.6.

The three sides of the right triangle is calculated as follows;

tan a = opposite / adjacent side

Length BC = opposite side = 3

Length AB = adjacent side =  7

The hypotenuse side of the right triangle is calculated as follows;

AC² = 3² + 7²

AC = √(3² + 7²)

AC = 7.6

Sin c = |AB| / AC

sin c = 7/7.6

sin c = 0.92

Thus, the value of sin c is 7/7.6.

The height of the prism that's depicted in the water tank will be 8m.

The area of the base of the triangular prism will be calculated thus:

= 1/2 × 4 × 9

= 18m²

The volume of water removed from the rectangular tank will be:

= (6 × 6) × 4

= 144m³

Therefore, the height will be calculated thus:

18 × h = 144

18h = 144

h = 144/18

h = 8m

Therefore, the height is 8m.

Answer:

The value of the car will be $2,363.19 after 14 years

Step-by-step explanation:

The rule of depreciating is  

[tex]A=p(1-r)^{t}[/tex] , where

∵ A new car is purchased for 18000 dollars

∴ P = 18,000  

∵ It depreciates at a rate of 13.5% per year

∴ r = 13.5% = 13.5/100 = 0.135  

∵ We need to find how much it will be worth after 14 years

∴ t = 14

→ Substitute all of these values in the rule above to find A  

∵  [tex]A=18000(1-0.135)^{14}[/tex]

→ Use your calculator to find the answer  

∴ A = 2,363.186569

→ Round it to the nearest cent (2d.p.)

∴ A = 2,363.19

∴ The value of the car will be $2,363.19 after 14 years.

Answer:2*2*3*3

Step-by-step explanation:

If [m] represents the greatest possible length of line segment AD, and [p] represents the least possible length of line segment AD, than the value of [m - p] will be 2.84.

        where : [m] → is slope of line and [c] → is the y - intercept

We have in a plane, the lengths of line segments AB, BC, and CD are 3, 5, and 1.

Using the Pythagoras theorem, the length of side AC will be -

AC² = AB² + BC²

AC² = 9 + 25

AC² = 34

AC = √34

Also, we can write, the sum of two sides of a triangle is greater than the third side. So, in triangle ACD, we can write -

1 + √34 > AD

AD + √34 > 1

AD + 1 > √34

AD[min] = √34 - 1 = 4.84

AD[max] = √34 + 1 = 6.84

So -

m - p = 2.84

Therefore, if [m] represents the greatest possible length of line segment AD, and [p] represents the least possible length of line segment AD, than the value of [m - p] will be 2.84.

It is obtuse because the largest angle is over 90.

It is Isosceles because the two base angles are equal.
