Answer:
The correct option is B.
Step-by-step explanation:
Solution:
The shortest on map is 7cm
The longest on map is 14 cm
The shortest in real life is 120 km
Let the longest in real life is x km
So,
The ratio is:
7/120 = 14/x
x = 120*(14) / 7
x=1,680/7
x= 240 km
The longest in real-life is 240 km
Thus the correct option is B....
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
Answer:
n=46
Step-by-step explanation:
Since this is a right triangle, you are left with 90 degrees
2n-2=90
2n=92
n=46
Answer:
x=2
Step-by-step explanation:
7x+9=9x+5 [Corresponding angles]
9-5=9x-7x
4/2=x
x=2
Answer:
x > 2
Step-by-step explanation:
7x +39 > 53
AND
16x + 15 > 31
7x > 14
AND
16x > 16
x > 2
AND
x > 1
And is intersection, which is x > 2
