Check the picture below.
now, let's rationalize the denominator for "r" first.
also notice, that section is just 1/4 of the area of that circle, so, let's just find the area of the whole circle with that "r", get one-quarter of it, and subtract it from the half of the area of the square.
Answer:
Step-by-step explanation: One number is four more than the other." is represented as 'x'
"One number is four more than the other." is represented as 'x+4'
"Their sum is fourteen." is represented as 'x+(x+4)=14'
"Find both numbers."
x+(x+4)=14
x+x+4=14 (add like terms)
2x+4=14 (isolate your 'x' variable on one side of the equality by subtracting 4 from both sides)
2x+4-4=14-4
2x=10 (isolate your 'x' variable by dividing by 2 from both sides)
2x/2=10/2
x=5 (this is the answer to one number)
x+4=5+4=9 (plug in 5 for 'x' and this is the answer to four more than another)
Your two numbers are 5 and 9.
Answer:
grab a ruler and put the 0 on the inches side up to the R and she what it's at when it hits S and do it again at T
Answer:
4.4 x 10^9
Step-by-step explanation:
(8.8 x 10^6)(5 x 10^2)
Multiply the 8.8 and 5
8.8 x 5 = 44
Add the powers (don't touch the 10s)
6 + 2 = 8
Right now we have: 44 x 10^8 but this isn't in scientific notation. The decimal must have a SINGLE digit to the left of it; no more no less.
Move the decimal over one place to the left.
44 turns into 4.4
This action adds another power
8 + 1 = 9
Thus our final answer is: 4.4 x 10^9
Answer:
The results do not in anyway represent the population reason been that the sample does not represent professors from different areas but only tend to represent 50 professors from his hometown university
Step-by-step explanation:
Based on the information given the results of his survey does not in anyway represent the entire response from the population of college professors reason been the surveys carriedout by him was only for 50 professors from the university in his hometown and not professors from different areas which means that the sample or survey about the amount of money that average college professor make collected by him was not accurate.
Therefore for him to have accurate result he have to survey professors from different area which will inturn give him the accurate sample
