Percentage homeworkkk… (Middle School)

Mathematics
2 answers:
frez [133]2 years ago
5 0

Step-by-step explanation:

1.) 50% off 125.00 is 62.50

The difference is 62.50

$100%=62. 50​.

2.) 30%

12-5=7

100%

So if you take 10-7=3

So 100%-70%=?

30%.

3.) Theodore 84% of the questions right.

If you wanted to know the percentage he got wrong then it is 16% wrong and 84% right.......

4.) 88 pages, Because 40% of 220 is 88.

PLEASE HELP ME!
kotegsom [21]

Answer:

Bottom left graph

Step-by-step explanation:

We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

−2x + y ≤ 4 >> Original Standard Equation

+ 2x + 2x

_________

y ≤ 2x + 4 >> Slope-Intercept Equation

−2[0] + 0 ≤ 4

0 ≤ 4 ☑ [We shade the part of the graph that CONTAINS THE ORIGIN, which is the right side.]

\displaystyle y > x + 2 \\ \\ 0 ≯ 2[We shade the part of the graph that does not contain the origin, which is the left side.]

So, now that we got that all cleared up, we can tell that the graphs share a region in between each other and that they both have POSITIVE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], therefore the bottom left graph matches what we want.

** By the way, you meant \displaystyle y > x + 2because this inequality in each graph is a <em>dashed</em><em> </em><em>line</em>. It is ALWAYS significant that you be very cautious about which inequalities to choose when graphing. Inequalities can really trip some people up, so once again, please be very careful.

I am joyous to assist you anytime.
