Answer:$17.40
Step-by-step explanation:
This is a very simple question. First since 70% is the amount of money removed, we do 100-70=30
30% is the price that remains. Change that into a fraction 30/100 and then multiply the original cost
30/100*58=17.4
The answer is $17.40

9514 1404 393
Answer:
- -√5
- 3/5
- -4/5
Step-by-step explanation:
The relevant relations are ...
sec = ±√(tan² +1)
cos = 1/sec
csc = 1/sin = ±1/√(1 -cos²)
Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.
__
1. sec(θ) = -√((-2)² +1) = -√5
2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5
3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5
Set both fraction to a common denominator
7/16 and 4/16
now add them together
7/16 + 4/16 = 11/16
now subtract that from a full cake
16/16 - 11/16 = 5/16
there are 5/16 of the cake left
