Answer:
so what you have to do first is simplify into variables
S=A 3/4 stack of index cards
C= 3/160
first you can do this with a calculator, divide 3/4 of an inch by 3/160 of an inch.
3/4÷3/160=40
Here is my work shown :)
Male the division into multiplication and swap the numbers in 3/160 to 160/3
3/4 x 160/3
For fraction multiplication, multiply the numerators and then multiply the demoninators to get
3 x 160/4 x 3= 480/12
Divide 480 by 12 which is forty
there you go :) sorry if the answers are messed up and there are spelling errors. but in conclusion the answer is 40
By the way, awesome pfp, I just started watching Toilet Bound Hanako earlier tonight and it's very good so far
David made 30 cups of tea per hour. David worked for D hours. In D hours, he made 30D cups of tea. Then he made an additional 10 cups of tea, so this week, he made 30D + 10 cups of tea.
Andrew made 35 cups of coffee per hour. Andrew worked for A hours. In A hours, he made 35A cups of tea.
The total cups of tea and coffee made this week is:
30D + 10 + 35A

Answer:
54deg
Step-by-step explanation:
We need to compute the inverse cosine of 10/17. I can't do it by hand, so I used a calculator and it arrived at ~53.97deg which is 54deg rounded to the nearest tenth.
