Pls help solve by finding the square roots​

Mathematics

gayaneshka [121]3 years ago
5 0

Answer:

No real solutions

Step-by-step explanation:

Step 1: Add 8 to both sides.

  • 2r^2-8+8=-27+8
  • 2r^2 = -19

Step 2: Divide both sides by 2.

  • (2r^2)/2 = -19/2  
  • r^2 = -9.5

Step 3: Take the square root of both sides.

  • r = \sqrt{-9.5}
  • (We can't square root negative numbers, otherwise, they become i)

Therefore, the answer is no solutions.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

seraphim [82]

Answer:

  1.4%

Step-by-step explanation:

Avery's error was ...

  measured - actual = 14.7 in - 14.5 in = 0.2 in

As a fraction of the actual length, that is ...

  (0.2 in)/(14.5 in) × 100% ≈ 1.4%

The measurement error was about 1.4%.

10 POINTS ARE AWARDED! :(
amid [387]

Answer:

Step-by-step explanation:

An index number is a number which is raised to a power. The power, also known as the index, tells you how many times you have to multiply the number by itself. For example, 2^5 means that you have to multiply 2 by itself five times = 2×2×2×2×2 = 32. There are a number of important rules of index numbers: y^a × y^b = y.

1.5d+3.25=1+2.25d. What is d?
DochEvi [55]
Simplifying
1.5d + 3.25 = 1 + 2.25d

Reorder the terms:
3.25 + 1.5d = 1 + 2.25d

Solving
3.25 + 1.5d = 1 + 2.25d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-2.25d' to each side of the equation.
3.25 + 1.5d + -2.25d = 1 + 2.25d + -2.25d

Combine like terms: 1.5d + -2.25d = -0.75d
3.25 + -0.75d = 1 + 2.25d + -2.25d

Combine like terms: 2.25d + -2.25d = 0.00
3.25 + -0.75d = 1 + 0.00
3.25 + -0.75d = 1

Add '-3.25' to each side of the equation.
3.25 + -3.25 + -0.75d = 1 + -3.25

Combine like terms: 3.25 + -3.25 = 0.00
0.00 + -0.75d = 1 + -3.25
-0.75d = 1 + -3.25

Combine like terms: 1 + -3.25 = -2.25
-0.75d = -2.25

Divide each side by '-0.75'.
d = 3

Simplifying
d = 3
