Which is a true statement? A.
–11.1 > 10.7

B.
6.52 < 6.5

C.
–7.75 < –8.45

D.
–2.8 > –3.5

Answers

Answer 1
Answer: As a negative number cannot be larger than a positive number, the answer is not A.
6.52 is larger than 6.5 so it cannot be B.
A smaller negative number is larger than a big negative number so the answer is not C.

The answer is D. as -2.8 is larger than -3.5
Answer 2
Answer: A) -11.1 \ \textgreater \ 10.7 is false. No solution.

B) 6.52 \ \textless \ 6.5 is false. No solution.

C) -7.75 \ \textless \ -8.45 is false. No solution.

D) -2.8 \ \textgreater \ -3.5 is true. Infinite solutions.

Answer: \fbox {D) -2.8 \textgreater -3.5}

what are the solutions to the quadratic equation (5y 6)2 = 24? y = and y = y = and y = y = and y = y = and y =

Answers

If you would like to find the solutions to the quadratic equation (5y + 6)^2 = 24, you can do this using the following steps:

(5y + 6)^2 = 24
25y^2 + 2 * 6 * 5y + 36 = 24
25y^2 + 60y + 36 - 24 = 0
25y^2 + 60y + 12 = 0
25 * (y + 6/5)^2 - 24 = 0
1. y = -6/5 - (2 * sqrt(6))/5
2. y = (2 * sqrt(6))/5 - 6/5

The correct result would be y = -6/5 - (2 * sqrt(6))/5 and y = (2 * sqrt(6))/5 - 6/5.

The solution to the quadratic equation is y = -2.18 and y = -0.22

How to evaluate the function?

The equation is given as:

(5y + 6)^2 = 24

Expand

25y^2 + 60y + 36 = 24

Subtract 24 from both sides

25y^2 + 60y + 12 = 0

Using a graphical tool, we have the solution to be:

y = -2.18 and y = -0.22

Hence, the solution to the quadratic equation is y = -2.18 and y = -0.22

The curved surface of cylinder is 484 cm^2 and height is 5.5 cm. Find its radius.​

Answers

Answer:

r=14cm

Step-by-step explanation:

Curved Surface area of a cylinder=484cm²

Height=5.5cm

r=?

Curved Surface Area=2πrh

484=2×3.142×r×5.5

484=34.56r

r=484/34.56

r=14cm

Answer:

radius= 14

Step-by-step explanation:

curved surface area of cylinder = 484

height = 5.5

C.S.A = 2πrh

or, 484 = 2×22/7×r×5.5

or, 484×7 = 2×22/7×5.5×r

or, 3388 = 242×r

or, 3388/242 = r

or, 14 = r
