Answer:

12.2

Step-by-step explanation:

$d=√((x_2-x_1)^2+(y_2-y_1)^2)\n\nd=√((1-11)^2+(3-10)^2)=√((-10)^2+(-7)^2)=√(149)\n\nd=12.2065...\approx12.2$

Use factoring. What is the solution of 2x² = 14x + 60? a. x = -15, x = 4 b. x = -10, x = 3 c. x = 15, x = 12 d. x = 10, x = -3

Answers

Answer: d. x = 10, x = -3

Step-by-step explanation:

We will solve by factoring as asked.

Given:

2x² = 14x + 60

Subtract 2x² from both sides of the equation:

0 = -2x² + 14x + 60

Factor:

0 = −2(x − 10)(x + 3)

Zero-product property:

x - 10 = 0 x + 3 = 0

x = 10 x = -3

d. x = 10, x = -3

If the radius of mars is about 13.7% of neptune's radius, what is the radius of neptune?

Answers

You said that M is 13.7% of N

In algebraic notation M = 0.137 N

Divide each side by 0.137 : N = M / 0.137 = 7.3 M (rounded)

Online or in a real book, you can look up the radius of Mars.
Then write it in place of 'M' in this solution, and you'll have
an actual number for the radius of Neptune.

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?70
85
110
143

Answers

First divide 28 by 40 to get the unit rate which is 0.7. Then, since that is 1% mulitiply 0.7 times 100 to get 70 turtles as your answer. hope that helped!

28=.4x
70=x
They found 70
