Answer:

B: $74

Step-by-step explanation:

To find out how much Ashley made, you need to find how much 74% is of 200. The answer to this is 148. Since Chris made 1/2 of what Ashley did, we have to divide 148 by 2. And you get 74

Which linear inequality is shown on the graph?

Answer: choice C) x-y <= 2

======================================

Explanation:

The two points (0,-2) and (2,0) are on the boundary line. The boundary line equation is y = x-2. We find this equation through the use of the slope formula to find that m = 1. The y intercept is -2 so b = -2. Therefore, y = mx+b turns into y = 1x+(-2) which simplifies to y = x-2

The equation y = x-2 can be arranged to get x-y = 2 (subtract y from both sides; add 2 to both sides)

So the answer is either x-y <= 2 OR it is x-y >= 2

The question is: which inequality has the test point (0,0) in it? We pick on the origin since 0 is the easiest number to work with.

Plug (x,y) = (0,0) into the equation for choice C
x-y <= 2
0-0 <= 2
0 <= 2
which is true. So choice C is the answer.

Choice D can be ruled out since...
x-y >= 2
0-0 >= 2
0 >= 2
which is false: 0 is not larger or equal to 2

Jeremy is writing down a sequence of integers. He writes 1 as his first number. Then, he

Pachacha [2.7K]

Answer:

<em>4 is the unit's digit of the 20th number.</em>

Step-by-step explanation:

Let us try to find out a pattern for the unit's digit of the terms.

1st term is 1, so unit's digit of 1st term is 1.

2nd term $1^{2} + 3 = 4$ so unit's digit is 4.

3rd term $4^{2} + 3 = 19$ so unit's digit is 9.

4th term $19^{2} + 3 = 364$ so unit's digit is 4.

5th term's unit digit: Square of unit's digit of 4th term + 3

$4^{2} + 3 = 19$ i.e. 9.

We can see that the pattern is

3rd, 5th, 7th ...... terms have 9 as the unit's digit.

2nd, 4th, 6th.... terms have 4 as the unit's digit.

So, 20th term will have 4 as the unit's digit.

Please help me!!!!

Free_Kalibri [48]

Answer: (ln10)/6=t

Step-by-step explanation: e is an irrational number, like pi. Therefore the only variable to solve for is "t." Divide both sides by 4, then subtract (1/4) from both sides to get 10. Then take the natural log of both sides because you get rid of e on the left side, and you have the variable by itself. Natural log, or ln, represents loge base e, so dividing both sides by 6, we get t! I hope this helps!
