9×10^-3 + 24×10^-6 : 12×10-3
9×10^-3 + 2×10-3
11×10^-3
Surface area is the sum of the areas of each side of a three dimensional object.
There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.
So the surface area is:
2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2
35 kilometers in 7 hours would be 7/35 which is 5 kilometers an hour, in 3 hours it would be 15 kilometers
Answer:
9500
Step-by-step explanation:
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
The best estimate of a population is calculated as:
= N = mn/k
Where N = Estimate of the population
m = 950 pike
n = 100 pike
k = 10 tags
= 950 × 100/10
= 9500
The best estimate of he population = 9500
(p + 6)/8 = (p - 6)/7
7(p + 6) = 8(p - 6)
7p + 42 = 8p - 48
8p - 7p = 42 + 48
p = 90
