Answer:

0.4

1*3 = 3

7*? = 7n (7 of a variable)

3 = 7n (divide by 7)

3/7 = 0.4285

0.4285 rounded to the nearest tenth = 0.4

Answer:  31) d     32) c

<u>Step-by-step explanation:</u>

31)

A = {1, 3, 5, 15}

B = {2, 3, 5, 7}

A ∪ B = {1, 2, 3, 5, 7, 15}

C = {2, 4, 6, 8}

(A ∪ B) ∩ C = {1, 2, 3, 5, 7, 15} ∩ {2, 4, 6, 8} = {2}

<em>2 is the only number in both sets</em>

32)

The pattern is: reflection, add symbol, ..., reflection, add symbol.

The last image shown is: add symbol

So the next image will be: reflection (flipped to the left)

Can someone please help me

<h3>Answer: Choice D)  3n^2</h3>

"mono" means "one". I often think of "monorail" which means "one rail" to help remember this. So "monomial" means "one term". This reduces our choices to either C or D, as they show one term each. Choices A and B are ruled out as these are binomials, showing two terms each.

Choice C shows a cubic monomial since the exponent here is 3. So the degree is 3. We can rule out choice C.

Choice D has a 2nd degree monomial because the exponent is 2. The leading coefficient is 3 as this is the number to the left of the variable term. All of choice D fits with the description of "A monomial of the 2nd degree with leading coefficient of 3"

It's very easy!
.
First of all, add up all the amounts of all can flavors.
.
What do you think it approximates to?
.
I'd say 245.
.
Now, how much is 30 out of 245?
.
Around 24%.
.
So, what's 245/100? (100 because it is default maximum percentage number)
<span>.  
</span>2.45.
.
24 divided by 2.45?
.
Around 9%.
.
Your best guess is 10% or D.
