The product of 5 and a number n is at least 25
Crazy boy [7]
5n≥25
and if you divide 5 on both sides, n≥5 (I don't know if you are supposed to solve or simply put it in the equation form).

Product refers to multiplication. so 5 and n are being multiplied in the equation.
However, instead of using an equal sign, the sign for "greater than or equal to" must be used. "At least" is a term equivalent to "greater than or equal to".

I need help with this word problem.
zloy xaker [14]

Answer:

33 ⅓%

Step-by-step explanation:

Percent means out of 100, so write a proportion:

1 / 3 = x / 100

Solve for x by multiplying both sides by 100:

x = 100 / 3

Reduce:

x = 33 ⅓

The percent of questions he got right is 33 ⅓%.

What is the measure of angel A?
Rudiy27

Answer:

12.68°

Step-by-step explanation:

We know all three sides (18, 80, 82), but we only need two: 18, and 82. Why? What we do here is find the arcsin of the first leg divided by the hypotenuse.

arcsin(18/82)

<em>18/82 is the same as 9/41, which equals 0.21951 repeating (all 5 digits after the decimal are repeating, by the way).</em>

arcsin(0.21951)

<em>What you see above this statement equals 0.22131 radians.</em>

0.22131 rad

<em>To convert this to degrees, multiply by 57.2957795.</em>

0.22131 * 57.2957795

<em>0.22131 times 57.2957795 is 12.680128961145.</em>

12.680128961145°

<em>The directions say the final answer has to be two decimal places. So this becomes 12.68 (0 is less than 5, so round down).</em>

12.68°

Angle A is 12.68°.
