It is the difference of 2 squares as its of the form a^2 - b^2
A is the correct answer.
Answer: 4200
Assuming that this question is based on a graph, and that this graph tells us that people 50-64 years make up 35% of all the voters, then it would mean that
35%of 12000= 35/100 * 12000= 35 * 120= 4200
So, assuming that people at age 50-64 make up 35% of the voters, then 4200 of them voted.
Answer:
18 edges
Step-by-step explanation:
v-e+f=2
number of vertices(12) - number of edges (18) + number of faces(8) = 2
Answer: maximum "safe" Force = 415.58 N
Step-by-step explanation:
<u>Length = 1.2 m</u>
lower bound is 1.15 (because it rounds up to 1.2)
upper bound is 1.24 (because it rounds down to 1.2)
<em>Note: 1.25 would round up to 1.3</em>
<u>width = 2.5 m</u>
lower bound is 2.45 (because it rounds up to 2.5)
upper bound is 2.54 (because it rounds down to 2.5)
<em>Note: 2.55 would round up to 2.6</em>
<u>Pressure = 150 N/m²</u>
lower bound is 147.5 (because it rounds up to 150)
upper bound is 152.4 (because it rounds down to 150)
<em>Note: 152.5 would round up to 155</em>
<u>Max "safe" Force means minimum Area and minimum Pressure (lower bounds)</u>
Force = Area x Pressure
= length x width x Pressure
= 1.15 x 2.45 x 147.5
= 415.58
