Let x represent the amount of money each member can raise to meet the goal.

600+30x≥1500

60 is x% of 12. Find the value of x.

Liula [17]

Answer:

20

Step-by-step explanation:

We can set up a percentage proportion to find the value of x.

$\frac{12}{x} = \frac{60}{100}$

Now we cross multiply:

$100\cdot12=1200\\\\1200\div60=20$

Hope this helped!

using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?

mylen [45]

Correct Question:

Tim is investigating the relationship between the number of years since a tree was planted and the height of the tree in feet. His data are shown in the table. Years Since Tree was Planted vs. Height of Tree

Years since the tree was planted, x

Height of tree in feet, y

2, 17, 3, 25, 5, 42, 6, 47, 7, 54, 9, 69

Using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?

Answer/explanation:

There is no good prediction for the height of the tree when it is 100 years old. If you analyze careful in details the regression calculator you realize that it probably will not valid that far in to the future say 100 years.

Find the volume of a right circular cone that has a height of 2.7 ft and a base with a diameter of 14.4 ft. Round your answer to

irina1246 [14]

Answer:

V≈146.57ft^3

Step-by-step explanation:

V=πr^2·h/3 since d is 14.4, we would divide it by 2 to find the radius which is 7.2

so V= π(7.2)^2· (2.7)/3

V≈146.57ft^3

It would be greatly appreciated if you gave me the brainlest

Find all the interior angle measures of triangle ABC, if m∠A = 3x + 10, m∠B = 5x − 1, and m∠C = x. answers: m∠A = 60°, m∠B = 94°

tester [92]

Answer:

Step-by-step explanation:

Total interior angles in a triangle=180 degrees

That is: 3x + 10 + 5x - 1 + x =180

9x+9=180

9x=180-9

9x=171

x=171/9

x=19

Therefore

Angle A =67 degrees

Angle B= 94 degrees

Angle C = 19 degrees
