melisa1 [442]

Answer:

31°

Step-by-step explanation:

To convert Fahrenheit to Celsius is C= (F-32) * 5/9

So first do parenthesis 87-32= 55

Next multiply that number by 5/9 which is 30.55555555

Then round your answer = 31°

Standard Form: ax² + bx + c = 0
Quadratic Formula: $\displaystyle x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Step-by-step explanation:

Step 1: Define

Identify variables

x² - 5x + 6

↓

a = 1, b = -5, c = 6

Step 2: Solve for x

Substitute in variables [Quadratic Formula]: $\displaystyle x = \frac{5 \pm \sqrt{(-5)^2-4(1)(6)}}{2(1)}$
[√Radical] Evaluate exponents: $\displaystyle x = \frac{5 \pm \sqrt{25-4(1)(6)}}{2(1)}$
[√Radical] Multiply: $\displaystyle x = \frac{5 \pm \sqrt{25-24}}{2(1)}$
[√Radical] Subtract: $\displaystyle x = \frac{5 \pm \sqrt{1}}{2(1)}$
[√Radical] Evaluate: $\displaystyle x = \frac{5 \pm 1}{2(1)}$
Multiply: $\displaystyle x = \frac{5 \pm 1}{2}$
Add/Subtract: $\displaystyle x = \frac{4}{2}, \ \frac{6}{2}$
Divide: $\displaystyle x = 2, \ 3$

The distance around a meter is 9619 ft. find the diameter of the crater .use 22/7 for pie

DochEvi [55]

The circumference of a circle is found with the equation

C = 2 pi * r

Since we have the circumference we can find the radius. Then once we have the radius we can determine the diameter.

9619 = 2 (22/7) r
multiply each side by 7

67333 = 2*22*r
67333 = 44r

divide each side by 44
r = 67333/44 = 1530.295 rounded to the nearest hundredth = 1530.30

The diameter is 2 x the radius, so

1530.30 x 2 = 3060.6 ft

The diameter of the crater is 3060.6 ft
