Scenario:
a worker needs to repair a window on the second floor of a building
He is outside 3 feet way from the building
He starts walking and when he reaches the wall he is lifted 4 feet until reaching the window
What is the distance from the window to the point where he has standing before he start walking ?
2))This path forms a right triangle.2 sides are known but not the hypotenuse
Formula a^=b^=c^
a=4 b=3 c=x (Hypotenuse)
3)
Substitute
4^+3^=X^
16+9=x^
25=x^
5=x
Hypotenuse=5
The sides of the triangle formed in this situation are
4,3,and 5

Answer:
a) 5
b) 20
c) 28
d) 10
Step-by-step explanation:
a) 7-2=5
b) 2(7)+3(2)
= 14+6
= 20
c) 2(7)(3)= 28
d) (7-2)^2
= (14-4)
= 10
It’s D, 10.7
8 - (4.7 x (-1)) - 2 = 10.7
Answer:
C and D
Step-by-step explanation:
Population density is the ratio of population to area. Its units are persons per square mile. Here, you're being asked to compare the population densities of several countries to the average population density in several US states.
__
<h3>average</h3>
The idea of "average population density of the 10 states listed" is somewhat ambiguous. It could mean either of (a) the ratio of the total of the states' population to the total of their land area, or (b) the average of the population densities of the states. (In the attached, we computed both, but the answer remains the same using either number.)
When there are numerous identical calculations to be performed, it is convenient to let a spreadsheet do them. The attached spreadsheet shows the population densities for the 10 states and 5 countries listed.
Depending on how you define it, the average population density of the 10 states is about 10.5 or about 15.7 people per square mile. (15.7 is the average of the density numbers, found using the spreadsheet AVERAGE function.)
__
<h3>countries</h3>
The 5 countries have population densities ranging from about 7.7 to 236 people per square mile. Two of the countries have density below 10.5, so are the answers to the question asked.
Canada (C) and Iceland (D) have population density below the US state average.
