Answer:

Step-by-step explanation:

What is the Radius?

1.5

this is just 1/2. 1/2 of 3 is 1.5 (also you can look up how do you find the radius of a circle with the diameter to be sure, a calculator will come up and you can put in the diameter)

What is the Circumference?

9.4

You can figure out the Circumference by multiplying pi by the diameter. (also you can look up how do you find the circumference of a circle with the diameter to be sure, a calculator will come up and you can put in the diameter)

What is the Area?

7.1

how you find the area with just the diameter is 1 /4πd^2 (also you can look up how do you find the area of a circle with the diameter to be sure, a calculator will come up and you can put in the diameter)

I will give brainliest to the best answer to this question: Each year, the Department of Water Works measures the chloride conce

Maslowich

Answer:

The total change that will likely occur in 2 years is $=-3\frac{2}{3}$ mg/L

Step-by-step explanation:

Given : The first year, they found the chloride concentration changed by $-1\frac{3}{5}$ mg/L .

It is estimated that the chloride concentration will change $-2\frac{1}{15}$ mg/L the next year.

To find : What is the total change that will likely occur in 2 years?

Solution :

The chloride concentration changed by $-1\frac{3}{5}=-\farc{8}{5}$ mg/L in first year.

The chloride concentration will change $-2\frac{1}{15}=-\frac{31}{15}$ mg/L the next year.

The total change that will likely occur in 2 years is

$=-\frac{8}{5}+(-\frac{31}{15})$

$=\frac{-24-31}{15}$

$=\frac{-55}{15}$

$=\frac{-11}{3}$

In a mixed fraction - $=-3\frac{2}{3}$ mg/L

In the diagram below BD is parallel to XY what is the value of Y

LiRa [457]

Given:

BD is parallel to XY.

One of the angle is 85°

To find:

The value of y.

Solution:

Parallel lines BD and XY cut by a transversal line.

Angle y and 85° are alternate interior angles.

Alternate interior angle theorem:

If two parallel lines are cut by a transversal line, then the pairs of alternate interior angles are congruent.

⇒ y = 85°

The value of y is 85.
