8^2, 4^3, and 2^6 are 3 ways
Answer:
cos0 = 6.8556546i/23 or sqrt-47/23
Step-by-step explanation:
hypotenuse is 23, opposite is 24
we have to find the adjacent using the pythagorean theorem
24^2 + b^2 = 23^2
576+b^2=529
subtract
b^2=-47
b=sqrt-47
sqrt of -47 is 6.8556546i, there is an i since it is the square root of a <em>negative</em>
cos = adjacent/hypotenuse
Well he replace 1 of 3 then he has 3 and if he replaced a total of all three then he would have 3 I'm not all that sure tho sorry this question is kinda confusing
answer:
30 yd^2
step-by-step explanation:
- in order to find the area of a triangle, we can use: A = 1/2 · b · h
- A = area
- b = base
- h = height
plug in,
A = 1/2(b)(h)
A = 1/2(15)(4)
A = 1/2(60)
A = 30 yd^2
Answer:
The exact number would be 26.66666667 but it would be 26.
Step-by-step explanation:
Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.
