33.7777 this is the answer I got.
The number of ways for arranging is n!
Total sample = 30+20+18
= 68
Number of ways to arrange
= 68!
= 2.480035542437 x 10^96
20 children can get a serving of popcorn
Since each serving is 1/4 of a cup, each cup can provide for 4 children. Since there are 5 total cups, multiplying 5 by 4 will give you 20.
X - 4/2 ; where x = -1.6
Substitute x by its value.
-1.6 - 4/2 *as you notice, one number is in decimal and the other is in fraction form. We need to convert one form to the other to make the numbers like numbers so that solving the equation will be easier and less confusing.
4/2 can easily be converted into decimal by dividing 4 by 2 which equals to 2.
So, -1.6 - 2 = ? The operation is a subtraction, but the other number is in negative form, if both numbers have the same sign, we add them up and the sign is carried over to the sum.
-1.6 -2 = -3.6 * we add 1.6 + 2 = 3.6, then we carry over its negative sign = -3.6
Answer:
I'll give you three examples of tangents in the real world:
- <u>Ski on a snowy mountain.
</u>
- <u>A street under a car wheel.
</u>
- <u>The line formed between the armpit and a deodorant type roll on.</u>
Step-by-step explanation:
Remember <em><u>a tangent is a straight line that touches a curve in a point</u></em>, by this reason, you can search examples where there are curves (like the snowy mountain, car wheel and the deodorant type roll on in the answer), touched by a beeline (ski, street, and armpit) in just a point, in the same form, you can use as an example a ball on a soccer field and others. I don't know what examples gave you in the lesson but I'm sure at least one of the examples I give you must function.
