One inequality could be x>3. So when x = 4 this is true because 4 is greater than 3.

Answer:

28495.5 ft

Step-by-step explanation:

V=(4 /3)π(r^2)

r=radius=diameter/2

165/2=82.5

(4/3)3.14(82.5^2)

(4/3) x3.14x6806.25=28495.5ft

One of the advantages of graphs is they can give you a visual sense of unknown quantities.

Graphical Representation is a way of analysing numerical data. It exhibits the relation between data, ideas, information and concepts in a diagram. It is easy to understand and it is one of the most important learning strategies. It always depends on the type of information in a particular domain.

Advantages of graphs :-

It allows us to relate and compare data for different time periods. It is used in statistics to determine the mean, mode, and median of different data. It saves a lot of time as it covers most of the information in facts and figures. This in turn compacts the information.

Hence, the advantages can be they can give you a visual sense of unknown quantities.

Answer:

C. All rectangles are quadrilaterals.

Step-by-step explanation:

A quadrilateral is defined as a closed shape with four sides and angles. Therefore, a rectangle is a quadrilateral. A quadrilateral is the largest group of organization out of everything listed, so C must be correct because it is the only answer to sort a smaller group into a larger one.

Answer:

y = 2x+3

Step-by-step explanation:

You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.

To find the slope, compare the coordinates of the two points marked on the line,  (0,3) and (-3,-3).

slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2

Slope-intercept equation for line of slope 2 and y-intercept 3:

y = 2x+3

Answer:

17.) D

18.) C

19.) B

Step-by-step explanation:

I estimated around 70-80

we get x by setting up a proportion.

[tex]\frac{12}{2x+2}[/tex] = [tex]\frac{21}{5x-1}[/tex]

then we cross multiply.

12(5x−1) = 21(2x+2)

60x − 12 = 42x + 42

18x − 12 = 42

18x = 54

x = 3.

plug in 3 for x for LB, which is 2x + 2.

LB = 2(3) + 2 = 8

plug in 3 for x for BG, which is 5x - 1.

BG = 5(3) - 1 = 14

It is a little unclear when you state the problem what exactly is going on with that fraction. This is a common issue when you try to type up equations. On the right side, you have a fraction bar and then a bunch of stuff after it. We need to clear up what is supposed to be in the numerator and what is supposed to stay in the denominator. This is important not just for typing up questions on the internet to get help but in using your calculator as well. If what the equation means is that both "f" and "q+z" are in the denominator, but then on your calculator you type something 1 / 2 * f * ( q + z ), most calculators (e.g. TI 83/84 and almost any basic or scientific model) will interpret that as meaning only the 2 is on the bottom and the rest is on top.

If you meant the f and the q+z are on top, then Steve's answer is good.

If you meant the f and the q+z are supposed to be on the bottom, then we have a little bit different process.

First, write down the operations that are happening to q, and in what order they happen from inside out, that is, according to the regular PEMDAS rule:

1. z is added

2. 2f is multiplied

3. The result is divided into 1 (as opposed to being divided by 1).

So, to solve for q, we "invert" the order of operations and do the inverse operation of our 3 steps, and also in reverse order.

1. To get the big thing out of the denominator (Step 3), we will multiply both sides by 2f(q+z). Now we have:

C*2f(q+z) = 1, or as we normally write it,

2Cf(q+z) = 1

2. Now we have to adjust our steps just a little bit because we have the *C part too. So we will change Step 2 above to "2Cf is multiplied." We invert that by dividing, so we have:

q+z = 1/[2Cf]. Notice how I put brackets around the entire denominator so it's clear!

3. Finally to invert Step 1 we subtract z:

q = 1/[2Cf] - z
