An angle of a right triangle measures 65 degrees. If the length of the side opposite to the angle is 20 ft, what are the lengths of the two other sides?

Answers

Answer 1

Answer:

22.07 ft & 9.32 ft

Step-by-step explanation:

by sines rule :

20/sin 65° = r/sin 90° = y/sin 25°

r = 20×sin 90°/sin 65° = 20/0.9063

= 22.07 ft

y = 20×sin 25°/sin 65° =

20× 0.4226/0.9063

= 9.32 ft

Tara bought one share of Apple stock in 2018 for $43.75. Then, three years later, she sold it for $136.76. How much money did she gain/lose with this stock? What was her return on investment?

Answers

Answer:

Gain= $93.01

ROI= 212.59%

Step-by-step explanation:

Given data

Cost of apple share in 2018 = $43.75

Sale price of apple share= $136.76

1. Her gain is

Gain= Sales price- Cost price

Gain = 136.76-43.75

Gain= $93.01

2. ROI is

ROI= Gain/cost*100

ROI= 93.01/43.75*100

ROI=2.1259*100

ROI= 212.59%

What are you asking ?

You work at a public golf course. You have a budget of $300 for supplies for the month. The golf course can buy golf balls at a price of $0.80 each.
Write an inequality that states the number of golf balls you can buy at this price and still have $200 left in your budget for other items.


(please give nice clear real answers otherwise you will be reported, thank you soo much!)

Answers

Answer:

200 + 0.8x = 300

200 + 0.8x = 300

- 200 - 200

---------------------------

0.8x = 100

---------------

0.8 0.8

x = 125

Step-by-step explanation:

You have a TOTAL of 300 and want to spend it on the golf course. 200 MUST REMAIN in order to purchase other items. Golf balls are at a price of 0.8 EACH. The amount of golf balls that can be purchased is unknown so we can place x as the number of balls purchased for 0.8 each.

If a position on the ocean floor is 12 kilometers below the sea level, which value describes the elevation of the ocean floor

Answers

Answer:

- 12

Step-by-step explanation:

The sea level serves as a reference point and may be used to describe objacetsvir positions above or below it. Therefore, the sea level is regarded as a zero point or level. Hence, objects below are describes to be at a negative distance while those above are assigned the positive sign. Hence, for a position which is 12 km below sea level, then the object is said to be at a distance of - 12 km (below sea level takes the negative sign.)

5ft and 12ft What is the length of the hypotenuse? feet​

Answers

Answer:

The answer is 13 feet.

Step-by-step explanation:

Assuming that the lengths 5ft and 12ft are the legs of the triangle, use the  Pythagorean Theorem to find the unknown length of the hypotenuse:

a^2 + b^2 = c^2

Now, simply plug in the values of the triangle legs:

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

c = 13

Answer:

13 ft

Step-by-step explanation:

The formula to find the length of the hypotenuse is:

[tex]a^2+b^2=c^2[/tex]

---------------------------------------------------------------------------------------------------------------

So:

25 + 144 = 13

On Sunday, the wind chill temperature reached −36 °F. On Monday, the wind chill temperature only reached 1 4 of Sunday's wind chill temperature. What was the lowest wind chill temperature on Monday? A −144 °F B −36 1 4 °F C −9 °F D −40 °F

Answers

Answer:

(A) -9 °F

Step-by-step explanation:

On Sunday, the wind chill temperature reached - 36 °F. On Monday, the wind chill

temperature only reached¼ of Sunday's wind chill temperature. What was the

lowest wind chill temperature on Monday? (A) -9 °F (B) -36¼°F (C) -40 °F (D) -144 °F

Sunday temperature = - 36 °F

Monday temperature = ¼ of Sunday's wind chill temperature

Monday = 1/4 of - 36 °F

= 1/4 * -36 °F

= (1 * -36)/4 °F

= -36/4 °F

= -9 °F

Monday temperature = -9 °F

The correct answer is (A) -9 °F

Find an explicit rule for the nth term of the sequence.

-2, -8, -32, -128

Answers

Answer:

[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = - 8 ÷ - 2 = - 32 ÷ - 8 = - 128 ÷ - 32 = 4

This indicates the sequence is geometric with nth term

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = 4 , then explicit formula is

[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

whats the correct equation to solve for x

Answers

Answer:

12x - 29 + 4x + 1 = 180

Step-by-step explanation:

(12x - 29) and (4x + 1) are same- side interior angles and sum to 180° , then

12x - 29 + 4x + 1 = 180 ← is the equation to solve for x

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

what's the value of x and y?​

Answers

Answer:

x = 45 and y = 90

Step-by-step explanation:

Let the third angle be z

z = 180 - 135 (Linear Pair)

z = 45

Since its an iscosceles triangle,

<z = <x (angles opposite to equal sides have equal angles)

<x = 45 degree

<z + <x + <y = 180

45 + 45+ <y = 180

90 + <y = 180

<y = 180 - 90

<y = 90

Therefore x = 45 and y = 90

Hope u understood please mark as brainliest

Thank You

Answer:

x= 45°

y= 90°

Step-by-step explanation:

x= angles on a straight line add up to 180°. 180°-135° = x.

y= x+y=135° & x =45°

135°- 45° = y
