Answer:
The sine and cosine are equal for 45 degrees.
Choose the triangle that has a 45-deg angle.
The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.
Answer:
- A: 1/3, 2700
- B: 2/9, 1800
- C: 4/9, 3600
Step-by-step explanation:
The total number of ratio units is 3+2+4 = 9, so the fractions each school got were ...
A : B : C = 3/9 : 2/9 : 4/9
These fractions multiply the total amount raised:
A got 1/3 = 2700, B got 2/9 = 1800, C got 4/9 = 3600
