Answer:

Richter, the Richter scale was used for many years to describe the energy released by an earthquake. ... To estimate the Richter scale measure, write the amplitude, in mm, as 10 raised to an exponent (10x), then add 3 to the exponent, x. For example, if the amplitude is 100 mm, rewrite 100 as 102.

Answer:

2 gallons

Step-by-step explanation:

There are 4 (US) quarts in 1 (US) gallon.

4 + 4 = 8

Answer:

2, 2 gallons would be equal to 8 quarts

Step-by-step explanation:

4 quarts is a gallon so you would have 2

Answer:

5/6

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/6, 1/2) = 6

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(26×11)+(12×33)=?

Complete the multiplication and the equation becomes

26+36=?

The two fractions now have like denominators so you can add the numerators.

Then:

2+36=56

This fraction cannot be reduced.

Therefore:

26+12=56

Solution by Formulas

Apply the fractions formula for addition, to

26+12

and solve

(2×2)+(1×6)6×2

=4+612

=1012

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(10,12) = 2

10÷212÷2=56

Therefore:

2/6+1/2=5/6

A. Step 1

Step-by-step explanation:

He made the mistake on step 1 because he didn't distribute

Answer:

Step 1

Step-by-step explanation:

2(5g - 1) = 3

1 Step: Distribute

2(5g - 1) = 3

10g-2=3

2 step: Add 2 to both side of the equation

10g -2=3

10g= -2+2=3+2

3 step: Simplify

4 step: Divide both sides of the equation by the same term

10g=5

10g/10 = 5/10

5 step: Simplify

g = 1/2

Answer:

The second option

Step-by-step explanation:

c=[tex]\sqrt{16^{2} +12^{2} }[/tex]

c=20 m

The x=2+i is the root of the quadratic equation x²-4x-5=0. Therefore, option A is the correct answer.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

Given that, the roots of the quadratic equation are x= 2 + i.

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

A) x²-4x-5=0

Here, x=[4±√(16-20)]/2

x=[4±2i]/2

x=2±i

x=2+i or x=2-i

Therefore, option A is the correct answer.

C. [tex]1.18b[/tex]

Step-by-step explanation:

Hi! Ace here!

In order to do this, we have to convert 18% into a decimal.

The decimal form of it is .18.

So we have to do

I hope this helped

Answer:

1.18b

Step-by-step explanation:

Remember: percentage = decimal × 100

total = b + 18% x b

Factor out b:

total = b x (1 + 18%) = b x (1 + 0.18)

total = b x 1.18 = 1.18b

Answer:

Step-by-step explanation:

1). (10x - 27)° = (2x + 29)°

10x - 27 = 2x + 29

8x = 56

x = 7

m∠W = (2(7) + 29)° = 43°

2). (14x + 4)° + 51° + 55° = 180°

14x + 110 = 180

x = 14
