Answer 2
If should be a decagon. 72/2 (since we only need one of the angles) is equal to 36. 180-36 is 144. Decagons have internal angles of 144 degrees so that should be your answer.

A restaurant sells 10 tacos for $8.49, or 6 of the same kind of taco for $5.40.

Which is the better deal? Explain how you know.

Answer:

Part A: The equations are:

y = -1/2x + 2, and

y = 3x - 5

Part B: The solution is (2,1)

Step-by-step explanation:

Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2

For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5

Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.

Solve the system of equations

Y= -7x+3
Y= -x -3

What is X

The answer is X = 1 and Y = -4.

Answer: 0.8

The volume is 8/45 so a•b•c=8/45

So 2/3•1/3•a=8/45

Multiply 2/3•1/3=0.222222 or 2/9
So 2/9•a=8/45

Divide 8/45 / 2/9= 0.8
a=0.8

4 13 13 19 7 4 3 4 4 19 7 9 4 19 4 4 10 10 8 20


Which histogram represents this data?

Answers

Answer:

The 2nd one.

Step-by-step explanation:

First, put the numbers in order from least to greatest. This isn't required, but it makes it easier.

3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20

Then, for each range of shows watched (0-5, 6-11, etc.) from the graph, count how many numbers from the list fit into that range.

Use the process of elimination:

In 3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20, numbers from 0-5 show up 8 times, so you can rule out the last 2 graphs. Numbers 12-17 show up 2 times, so the first one is incorrect. That leaves you with the second histogram.

Put the numbers in order then group up all the numbers in the ranges they give on the chart like 0-5. Find how many numbers are go in the category 0-5
