HELP! PLEASE! I will mark you brainalist!!!!!

Answers

Answer 1

Answer:

Step-by-step explanation:

Problem a

a is an isosceles triangle. It has 2 sides marked as equal. Therefore the two angles marked in red are also equal.

The top angle = x

x + 70.5 + 70.5 = 180 All triangles have 180 degrees.

x + 141 = 180 Subtract 141 from both sides

x + 141-141 =180 - 141 Combine

x = 39

c + 39 + 87.2 =180 Combine the left

c + 126.2 = 180 Subtract 126.2 from both sides

c+126.2-126.2 = 180-126.2

c = 53.45

Answer: 53.45

Problem B

Comment

Problem b can only be found by taking the supplements of the two given angles. After that is done, the vertically opposite angle to d can be found because d is opposite the third angle.

Supplement of 115.6

Call the supplement = y

y + 115.6 = 180 Supplementary angles = 180 degrees

y +115.6-115.6 = 180 - 115.6 Combine

y = 64.2

Now we need the supplement of 99.9

Call the supplement = z

z + 99.9 = 180 Supplementary angles = 180

z+99.9-99.9 = 180-99.9

z = 80.1

Now subtract y + z from 180

180 - 64.2 - 80.1 = x

x = 35.7

x is opposite d

d = x

d = 35.7 degrees.

Answer

d = 35.7

What is the square root of A=121 ft2

Answers

The result of the square root of the equation A = 121 ft² is √A = 11 ft

What are square roots?

Square roots are numbers multiplied by itself to give another number

How to determine the square root?

The equation is given as:

A = 121 ft²

Take the square root of both sides

√A = √121 ft²

Evaluate the square root

√A = 11 ft

Hence, the square root of the equation A = 121 ft² is √A = 11 ft

Find sin 2x if cos x=-2/3 and x is in quadrant 2

Answers

Answer:

-4√5/9.

Step-by-step explanation:

if cos x = -2/3 then sin x = √(1 - (-2/3)^2)

= √(5/9)

= √5/3.

(As x is in quadrant 2 sin x is positive).

So:

sin2x = 2 sin x cos x

= 2 * √5/3 * -2/3

= -4/3 * √5/3

= -4√5/9.

Jeff Krause purchased 1,000 shares of a speculative stock in January for $1.89 per share. Six months later, he sold them for $9.26 per share. He uses an online broker that charges him $10.00 per trade. What was Jeff's annualized HPR on this investment?

Thanks!

Answers

Based on the price he purchased the stock and the amount he sold them for, Jeff's annualized HPR on the investment is 2,395%.

How much is Jeff's annualized HPR?

First find the net profit:

= (1,000 x 9.26) - (1,000 x 1.89) - 10

= $7,360

The HPR is:

= 7,360 / (1,000 x 1.89)

= 389.4%

The annualized HPR is:

= (1 + 389.4%)² - 1

= 2,395%

Note: Taken to the power of 2 because there are two six-month periods in a year.

Find the volume of the cylinder.
Either enter an exact answer in terms of TT or use 3.14 for T.

Answers

Answer :

Volume is 471 unit^3

Step-by-step explanation :

Here we have been given with the radius and height of a cylinder that is 5 unit and 6 unit respectively. We need to calculate the volume of cylinder so we would be using its formula. V = πr^2h

Here,

h is heightr is radius

We have :

r = 5 h = 6

Substituting the values :

>> V = 3.14 × (5)^2 × 6

>> V = 3.14 × (5 × 5) × 6

>> V = 3.14 × 25 × 6

>> V = 3.14 × 150

>> V = 471

Volume of cylinder = 471 units .

As a supplement to her husband's income, Anna began teaching the daughter of James Webb, the owner of the town's general store. Two years later, Anna opened one of the first all-female academies in North Carolina, the Burwell Female School. In addition to being the founder of the Burwell Female School, Anna was also the full-time administrator. She created the curriculum for the school's classes, which included Latin, botany, astronomy, and physical education. Many students traveled from out of state to attend the school, and these students shared the Burwell home with Anna, her husband, and their growing family (which eventually included twelve children). Over the course of twelve years, two hundred students were educated at the Burwell's school. Anna shared her love for education with her students.
