Answer:
0.92
Step-by-step explanation:
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
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.

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
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.

Answer:
one blue triangle is equal to 4
x = 4
Step-by-step explanation:
ok so lets say one red circle is equal to y so
y = 2
there is 4 circles so it would be
4y = 4 * 2 = 8
then the blue triangles are x and are equal to
2x = 2 * x = ?
8 / 2 = x = 4
x = 4

An article bought for Rs1000 is sold in fourth-fift of the cost prize . What is the profit percentage?
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%
-20%

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