Answer: 0.9

Step-by-step explanation:

Let x be the number

Determine the value of the number

x² = 81

√x² = √81

x = 9

Find the 10% of the number

Final number = rate of percentage × original number

Final number = 10% × 9

Final number = [tex]\boxed{0.9}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Step-by-step explanation:

Given,

SinA = 4/5

CosA =4/5

TanA= 3/4

CotA = 12/13

Sin²A = SinA²

Cos²A = CosA²

Tan²A = TanA²

Cot²A = CotA²

Therefore,

Sin²A = (4/5)²

Cos²A = (4/5)²

Tan²A = (3/4)²

Cot²A = (12/13)²

Sin²A = 16/25

Cos²A = 16/25

Tan²A = 9/16

Cot²A = 144/169

Answer:

1120 inches squared

Step-by-step explanation:

change the 4 separate boxes into a single box with dimensions 10 by 12 by 20 (5+5+5+5=20) then find the surface area:

2(20*12 + 20*10 + 12*10)=2(240+200+120)=2*560=1120

Answer:

The answer is 69

Step-by-step explanation:

The sum of a number and 98 means it equals 167. So all you have to do to find the missing number is plug it in to the equation.

?+ 98= 167

167-98=?

Answer:

The answer is 9 hours and 25 minutes

Step-by-step explanation:

if it starts at 6:05 am and then ends at 3:30 pm then thats 9 hours in total and 25 minutes

Answer:

8

Step-by-step explanation:

8.2, since 2 is smaller than 5, it would eliminate it, rounding it to just 8.

A little summary of the question:

The question has asked you to turn the shape 180° counterclockwise. that in simpler words means flipping the shape 2x right making a mirrored reflection of the shape.

Answer:

around 502.65

Step-by-step explanation:

so, find the area of the circle first which is 16ft x 16ft x pi

after that, since a circle is 2 pi radians, just take 5/4 ÷ 2

then multiply that number over your area.

I'm not sure if I'm correct but this is what I know based on my limited understanding of it

Answer:

10

Step-by-step explanation:

I'm pretty sure the segment addition postulate just means that if you add JK and KL together, you'll get the length of JL. Correct me if I'm wrong...

Anyways, JK = 3x - 4, and KL = 5x + 6. If we add these together, according to the segment addition postulate, we will get JL, which equals 9x - 8. So, we set up an equation:

3x - 4 + 5x + 6 = 9x - 8

Simplifying this equation, we get:

8x + 2 = 9x - 8

x = 10

So, our answer is 10.

(also you ask for segment EF but I don't see segment EF so I'm going to just answer the question in the picture)

Answer:

A) $49

Step-by-step explanation:

There are two ways to solve this problem. You could either calculate the net change by adding up the values in the table and then adding that to the initial amount, or you could individually add every change in price to the initial amount. I'm going to go with the first way, as I find it to be quicker, but both methods work equally well.

We know that the stock was worth $52 on Monday morning. From the table, the net (or overall) change in the stock over the course of the week is:

-2 + 1 + 3 - 1 - 4 = -3

Therefore, the stock's price decreased by $3 over the week, and because the stock's original price was $52, we know it is now worth 52 - 3 = $49. Hope this helps!

Answer:

D

Step-by-step explanation:

Step-by-step explanation:

the line passes (-10, 0) and ( (0, 8) =>

the slope = (8-0)/(0-(-10) = 8/10 = 4/5

so, the equation :

y - 8= 4/5 ( x-0)

y -8 = 4/5 x

=> y = 4/5 x + 8

Answer:

second option ∠C = 60 degrees

Step-by-step explanation:

To find the angle C

we know that the sum of all interior angles of triangle is 180

∠A + ∠B + ∠C = 180 (sum of interior angles)

90 + 30 + ∠C = 180

120 + ∠C= 180

∠C = 180 - 120

∠C = 60

Answer: B. 60

Concept:

Here, we need to know the idea of the triangle angle sum theorem.

The triangle angle sum theorem states that the sum of interior angles is 180 degrees.

Step-by-step explanation:

Given information

∠A = 90°

∠B = 30°

∠C = unknown

Given expression deducted from the triangle angle sum theorem

∠A + ∠B + ∠C = 180

Substitute values into the expression

90 + 30 + ∠C = 180

Combine like terms

120 + ∠C = 180

Subtract 120 on both sides

120 + ∠C - 120 = 180 - 120

∠C = [tex]\boxed{60}[/tex]
