Please Help I Have Tried So Many Times And No One Helps Me Please

Answer 1

Answer:

m(arc)RST = 154 deg

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary.

x + 77 + x + 103 = 180

2x + 180 = 180

2x = 0

x = 0

m<RST = x + 77 = 0 + 77 = 77

The measure of an inscribed angle is half the measure of its subtended arc.

m<RST = (1/2)m(arc)RST

77 = (1/2)m(arc)RST

154 = m(arc)RST

m(arc)RST = 154 deg

An article bought for Rs1000 is sold in fourth-fift of the cost prize . What is the profit percentage?

Answers

Answer:

-20%

Step-by-step explanation:

Given that :

Purchase price = Rs1000

Price sold = 4/5 of the purchase price

Price sold = 4/5 * 1000 = Rs. 800

Profit Percentage :

(price sold - purchase price) / purchase price * 100%

(800 - 1000) / 1000 * 100%

(-200 / 1000) * 100%

-0.2 * 100%

Find the common ratio of the geometric sequence 36, 6, 1, 16, ... . Write your answer as an integer or fraction in simplest form.

Answers

Answer:

Step-by-step explanation:

The common ratio is the constant found by dividing any term by the previous term.

r=6/36=1/6

r=1/6

I am assuming the 16 at the end of the sequence was a typo. IF 16 was at the end of the sequence it is NOT a geometric sequence as there would not be a common ratio for all terms.

What are the zeros of f(x) = x2 + x – 30?
A. x = –6 and x = 5
B. x = –5 and x = 6
C. x = –15 and x = 2
D. x = –2 and x = 15

Answers

When you factor our f(x)=x^2+x-30, you get (x+6)(x-5). In order to get your zeroes you need to plug in values that would make each of those two parentheses equal to zero. So in this case since -6+6=0 and 5-5=0, your zeros would be x=-6 and x=5.

Answer:

Answer A is correct.  (x + 6)(x - 5) = x^2 + x - 30.

Step-by-step explanation:

Note that -30 = (-5)(6) and (5)(-6). This quadratic can be factored easily:

x^2 + x - 30 = (x + 6)(x - 5) is correct because 6x - 5x = x, the middle term of x^2 + x - 30.

Setting each factor equal to zero, one by one, we get:

x + 6 = 0 => x = -6, and x - 5 = 0 => x = 5

Answer A is correct.

find the values of x and y.​

Answers

Answer:

x = 20, y = 70

Step-by-step explanation:

The angle adjacent to 40° is 180° - 40° = 140°

Since the triangle on the right has 2 congruent sides then it is isosceles and its base angles are congruent,  both x

2x + 140 = 180 ← sum of 3 angles in triangle

Subtract 140 from both sides

2x = 40 ( divide both sides by 2 )

x = 20

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

The angle inside the triangle on the left is 90° - 20° = 70° , then

y = 180 - (40 + 70) = 180 - 110 = 70

Mr. Lenny has graded 25% of his 200 students papers. How many papers did he finish
grading?
A
50
B.
60
с
25
D
300

Answers

Answer:

50 papers

Step-by-step explanation:

50% of the 200 papers would be 100 papers graded because half of 200 is 100.

25% would be 1/4 of the 200 papers.

So you have to divide.

200 divided by 4 is 50.

Therefore 50 papers have been graded so far.
