Answer:
50 girls
Step-by-step explanation:
Given data
We have the ratio as
7:10
The total part = 7+10= 17
let the number of boys and girls be x
applying the part to all method
7/17= 35/x
cross multiply
7x= 35*17
7x=595
x=595/7
x= 85
Hence the number of girls is
=85-35
=50 girls
Answer:
577,220 will be the population I think
Step-by-step explanation:
370,000/100=3700=1%
3,700*7=25,900
25,900*8=207,200
370,000+207,200=577,220
Answer:

Answer: The answer is √6 mi.
The formula is: d = √(3h/2)
Pam:
h = 324 ft
d = √(3 * 324/2) = √486 = √(81 * 6) = √81 * √6 = 9√6 mi
Adam:
h = 400 ft
d = √(3 * 400/2) = √600 = √(100 * 6) = √100 * √6 = 10√6 mi
How much farther can Adam see to the horizon?
Adam - Pam = 10√6 - 9√6 = √6 mi
