Percent increase and decrease. Original number:45 New number: 18

Mathematics
1 answer:
andre [41]3 years ago
4 0

Answer:

60% decrease

Step-by-step explanation:

To find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%

here the decrease = 45 - 18 = 27

percent decrease = \frac{decrease}{original} × 100%

                             = \frac{27}{45} × 100% = 60%

What is the answer to 18 - 3w = 4w
adelina 88 [10]

Answer:

Step-by-step explanation:

18 - 3w = 4w

Let's get all of the terms with the w on the right-hand side of the equation, and everything else on the left-hand side of the equation.

To do this, we should add 3w to both sides of the equation to remove the -3w from the left-hand side of the equation:

18 - 3w + 3w = 4w + 3w

18 = 7w

Finally, to get the w by itself, we can divide both sides by 7:

\frac{18}{7} = \frac{7w}{7}

w = \frac{18}{7}

What is the inverse of the relation? <br> {(-4,1), (-4,3), (0,-8), (8,-9)}
BigorU [14]

The inverse relation would be each of these ordered pairs switched.

{(1, -4), (3, -4), (-8, 0), (-9, 8)}

This is because when you create an inverse equation, all of the inputs become outputs and all of the outputs become inputs. Therefore, the ordered pairs simply switch.

A diameter is twice the radius. Here, we can use the formula d=2r (d=diameter r=radius)

If we substitute the formula, we have

d=2(35795)

After multiplying:

d=71518 kilometers
