I'll do the first two to get you started
===============================================
Problem 1
A = 3 = starting value
B = 10 = ending value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (10-3)/3 ] * 100%
C = (7/3) * 100%
C = 2.3333333 * 100%
C = 233.33333%
C = 233.3%
The positive C value means we have a percent increase. If C was negative, then we'd have a percent decrease.
<h3>Answer: 233.3% increase</h3>
===============================================
Problem 2
A = 9 = start value
B = 20 = end value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (20-9)/9 ] * 100%
C = (11/9)*100%
C = 1.2222222222*100%
C = 122.22222222%
C = 122.2%
<h3>Answer: 122.2% increase</h3>

From the given options, the graph that contains the points (0,0) and (1,3) is Graph D.
The correct answer is Graph D.
Answer:
The answer to your question is 2², 5 and, 7
Step-by-step explanation:
Data
140
Process
1.- Find the prime factors of 140, starting with 2, then, 3, 5, 7, etc
140 2
70 2
35 5
7 7
1
2.- Write 140 as a composition of prime factors
140 = (2²)(5)(7)
3.- Conclusion
The prime factors of 140 are 2², 5 and 7
8.75 an hour would be 350 for 40 hours.
8.75 x 1.5 = 13.13
13.13 x 12 = $158
so 350+158=508
so 508, probably 480ish after taxes for US
Answer:
B
Step-by-step explanation:
Using the trig. identity
cos x =
Given
secx = - , then
cos x = - × = - = - , thus
x = (- ) = → B
