Help me solve for q!<br><br> 21 + 3q &lt; 3 (13 - q)<br><br> How do you solve it? Thank you!
Molodets [167]
Good morning

21 + 3q < 3(13 - q)
21+ 3q < 39 - 3q Here it was -3q and it was on the left side. However when you are switching it to another terms that looks like it you must change the sign as well.
3q + 3q < 39 - 21 Here I bring the common terms together.
6q < 18
Divide both sides by 6
6q/6 < 18/6
q < 3

What is the inequality of 0 &lt; a &lt; 6 on a numberline
pickupchik [31]

The given inequality is expressed as

0 < a < 6

This means that the values of a that would satisfy the inequality are numbers between 0 and 6 but both 0 and 6 are not inclusive. This would be shown by not making solid circles at 0 and 6. The number line is shown below

Triangle XYZ, XY= 80, ZY= 64 XZ= 48 what is the cosine
SVETLANKA909090 [29]

Answer:

cos=\frac{4}{5}

Step-by-step explanation:

Cosine is the adjacent side over the hypotenuse (You can remember sin, cos, and tan by using sohcahtoa or sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite over adjacent). I think a picture would help, too.

I attached a picture of what I think the triangle would look like.

If the picture is right (we're assuming it is) and going with what we're given (the triangle was addressed as triangle XYZ, meaning that <u>angle Y is in the middle and that's the one we'll use</u>).

Looking at my picture then:

cos=\frac{64}{80} \\cos=\frac{8}{10} \\cos=\frac{4}{5} .

A perfect square is the square of an integer. Of the integers from 2 through 99, how many have at least one perfect square facto
N76 [4]

Answer:

Six numbers have perfect square factors

Step-by-step explanation:

The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.

They include:

4 = 2 * 2

16 = 4 * 4

36 = 6 * 6

49 = 7 * 7

64 = 8 * 8

81     = 9* 9

These numbers above have perfect square factors because they are formed from integers that multiply themselves.
