18/ 0.18 = 100
If you want in a calculator you type in what on top and you get 100. But on paper that's kind of hard to explain. Sorry.

WILL MARK BRAINLIEST The quadratic 10x^2+100x+1000 can be written in the form a(x+b)^2+c, where a, b, and c are constants. What

Sever21 [200]

$10x^2+100x+1000=10(x^2+10x+100)$
$=10(x^2+10x+25+75)$
$=10((x+5)^2+75)$
$=10(x+5)^2+750$
$\implies a=10,b=5,c=750$
$\implies a+b+c=765$

Evaluate 38+16 * 12÷2-(30 * 2)

Dvinal [7]

Answer

The answer is 8040

Step-by-step explanation:

It might be wrong, but here take it this way with Pemdas.

P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal = 8040 using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.

Use the dots for one and two. what is the difference between the ranges

sergij07 [2.7K]

Answer:

a. 20 points

Step-by-step explanation:

Range = Largest given value - Smallest given value.

Identifying the range of test 1

Looking at the dot plot the lowest test grade appears to be 50 while the highest is 90.

So range of test 1 = 90 - 50 = 40

Identifying the range of test 2

Looking at the plot the lowest test grade appears to be 40 while the highest appears to be 100

So range = 100 - 40 = 60

Identifying the differences between the ranges

Test 1 range : 40

Test 2 range : 60

Difference between the two : 60 - 40 = 20 points
