The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
should be 11
explanation:
when given a ratio turn it into a fraction and times it by the number.
15 × 3/4 is 11.25 so 11 teachers
Who came up wit the first one?!? Nah that’s to much!!
If there are no duplications among the six numbers, then they sit at
<em>six different points</em> on the number line.
Irrational numbers are on the same number line as rational ones.
The only difference is that if somebody comes along, points at one of them,
and asks you to tell him its EXACT location on the line, you can answer him
with digits and a fraction bar if it's a rational one, but not if it's an irrational one.
For example:
Here are some rational numbers. You can describe any of these EXACTLY
with digits and/or a fraction bar:
-- 2
-- 1/2
-- (any whole number) divided by (any other whole number)
(this is the definition of a rational number)
-- 19
-- (any number you can write with digits) raised to
(any positive whole-number power)
-- 387
-- 4.0001
-- (zero or any integer) plus (zero or any repeating decimal)
-- 13.14159 26535 89792
-- (any whole number) + (any decimal that ends, no matter how long it is)
(this doesn't mean that a never-ending decimal isn't rational; it only
means that a decimal that ends IS rational.
Having an end is <em><u>enough</u></em> to guarantee that a decimal is rational,
but it's not <em><u>necessary</u></em> in order for the decimal to be rational.
There are a huge number of decimals that are rational but never end.
Like the decimal forms of 1/3, 1/6, 1/7, 1/9, 1/11, etc.)
--> the negative of anything on this list
Here are some irrational numbers. Using only digits, fraction bar, and
decimal point, you can describe any of these <em><u>as close</u></em> as anybody wants
to know it, but you can never write EXACTLY what it is:
-- pi
-- square root of √2
-- any multiple of √2
-- any fraction of √2
-- e
-- almost any logarithm
Answer:
1. symmetric property
2. associative property of multiplication
3. The set is closed under addition and not closed under subtraction
