Answer:
2
Step-by-step explanation:
38 total students
5 like neither one, so 38 - 5 = 33
22 plus 13 is 35, but only 33 students like one of them, so 35 - 33 = 2 extra votes, which means 2 like both.
Answer:
0.05 decimal and 1/20 as fraction
Step-by-step explanation:
Answer:
The formula for an exponential decay problem is: y = x (1 - r)^x
Where x = initial amount, r = rate of decay and x = # time periods
So, x = $258, r = 8% = .08 and x = 11 years
y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10

Answer:
Internal base area of the water tank = 100 ft²
Step-by-step explanation:
Volume of cylinder = Base area x Height
Volume of cylindrical water tank = 1000 ft³
Height of tank = 10 ft
Base area = Volume of cylindrical water tank/Height of tank = 1000/10 = 100 ft²
Internal base area of the water tank = 100 ft²
Let's say we have the base -2 and we raise it to the third power, what will happen?
Well,
.
Any negative base with an odd exponent will result in a negative answer, because, unlike even exponents and negative bases, the negatives will not cancel out.
