Answer:
133.33 years
Step-by-step explanation:
Given that:
Principal = $500
Interest rate (r) = 1.5% = 0.015
Triple amount of principal = $500 * 3 = $1500 = final amount (A)
Number of years (t) =?
Using the relation :
A = P(1 + rt)
1500 = 500(1 + 0.015t)
1500 / 500 = 1 + 0.015t
3 = 1 + 0.015t
3 - 1= 0.015t
2 = 0.015t
2 / 0.015 = 0.015t / 0.015
133.333 = t
133.33 years
Okay so
area of picture= 192cm
area of frame= 40×24=960
960÷ 192= 5
Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24
The dimensions of the picture are then 8cm × 24 cm.
Answer: c
Step-by-step explanation: because yes
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
Football = 210 people = 42% on graph
210 ÷ 42 = 5
(Football People ÷ Percentage = People per percentage)
1% =5 people
100% = entire chart
100 × 5 people = 500 people
500 people were surveyed
Check work:
500 × .25 = 125 votes for soccer
500 × .33 = 165 votes for baseball
500 × .42 = 210 votes for baseball
= 500 total votes
