Answer:
16.67%
Step-by-step explanation:
If area triples every year :
This means that :
With an initial area of 10;
Area at the end of the year = 3 * 10 = 30
Percentage increase per year :
(30 - 10) / 10 * 100%
(20 / 10) * 100%
2 * 100%
= 200% per year
Therefore, monthly increase %
Yearly % increase ÷ number of months in a year
200% ÷ 12
= 16.666666%
= 16.67%
Answer:
7040.76 Joule
Step-by-step explanation:
In order to make yourself be able to climb upstairs, you need to work against the force of gravity. The force with which you pull yourself up is equal to the force of gravity exerted on you by the gravitational force.
So here, the net force involved is Mass(in Kg) multiplied by Acceleration due to gravity.
132 pounds = 59.8742 Kg
Net force = 59.87 × 9.8 = 586.73
As we know, the workdone is calculated by Multiplying the Net force with the Net displacement. Here, in this case the net displacement is 12 meters.
So,
Workdone = 586.73 × 12 = 7040.76 Joule
Answer:
80%
Step-by-step explanation:
If there are 400 people total and 80 of them have coupons, then 320 people don’t have coupons. Divide 320 by 400 and you will get 0.8, which is 80%.
12 since 12 is not negative. All absolute values r positive
Answer:
y=(-2/3)x-9
Step-by-step explanation:
1) first put the equation in terms of y. You should get y=-(2/3)x-8.
2) parallel lines have the same slope so the slope for this line and the answer should be the same
3) using the form y=mx+b plug (-2/3) in as the slope or m
4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b
5) isolate the variable b and plug in your answer to the equation.
