If we are to consider the number of slices of bread first,
number of sandwiches = (28 slices of bread)(1 sandwich/ 2 slices of bread)
number of sandwiches = 14 sandwiches
If we are to consider the number of slices of cheese
number of sandwiches = (45 slices of cheese)(1 sandwich / 3 slices of cheese)
number of sandwiches = 15 sandwiches
Since, 14 is smaller than 15 then, 14 is the answer.
<em>Answer: 14 sandwiches</em>
Answer:
a) 30 kangaroos in 2030
b) decreasing 8% per year
c) large t results in fractional kangaroos: P(100) ≈ 1/55 kangaroo
Step-by-step explanation:
We assume your equation is supposed to be ...
P(t) = 76(0.92^t)
__
a) P(10) = 76(0.92^10) = 76(0.4344) = 30.01 ≈ 30
In the year 2030, the population of kangaroos in the province is modeled to be 30.
__
b) The population is decreasing. The base 0.92 of the exponent t is the cause. The population is changing by 0.92 -1 = -0.08 = -8% each year.
The population is decreasing by 8% each year.
__
c) The model loses its value once the population drops below 1/2 kangaroo. For large values of t, it predicts only fractional kangaroos, hence is not realistic.
P(100) = 75(0.92^100) = 76(0.0002392)
P(100) ≈ 0.0182, about 1/55th of a kangaroo
Answer:
$1003.84615
Step-by-step explanation:
130.5 = x * 0.13
130.5/0.13 = x
x = 1003.84615
Answer:
x = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
x × = 9 ( divide both sides by )
x = 9
