Answer:
The answer to your question is 1 5/7 or 1.7 hours ≈ 1:43 min
Step-by-step explanation:
Data
Bob lasts 3 hours
Fred lasts 4 hours
Together = ?
Process
1.- Determine what they do in 1 hour
Bob = 1/3 in x hours x/3
Fred = 1/4 in x hours x/4
2.- Write the equation to this problem
x/3 + x/4 = 1
3.- Solve it for x
(4x + 3x)/12 = 1
7x = 12
x = 12/7
x = 1 5/7 or 1.7 hours ≈ 1:43 min
Answer:
Best Player: 30
Second Best: 28
Third Best: 26
Step-by-step explanation:
1) Break the percents down into smaller increments - 5% for example.
2) 5% or 1/20 of 40 (the whole) is 2.
3) Using this knowledge, we know that a player who makes 5% of his throws makes 2 shots.
4) 75% is made up of 15 groups of 5%, so that means if you multiply 15 by 2 (the number of shots made for every group of 5%), then you get 30.
5) 70% is made up of 14 groups of 5%, so that means if you multiply 14 by 2 (the number of shots made for every group of 5%), then you get 28.
6) 65% is made up of 13 groups of 5%, so that means if you multiply 13 by 2 (the number of shots made for every group of 5%), then you get 26.
Answer:
1. 7.5 hours
2. TV
3. Computer
4. All electronic usage except for the heater would decrease because summer is usually when people go outside and don't really stay indoors. While in winter, most people stay inside their houses.
Answer:
The equation of the line is y = 6x - 14
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (16 - 4)/(5 - 3)
m = 12/2
m = 6
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = 6(x - 3)
y - 4 = 6x - 18
y = 6x - 14
Answer:
Step-by-step explanation:
This problem is solved using the Pythagorean theorem (a2+b2=c2). In this formula a and b are the legs of the right triangle while c is the hypotenuse.
Using the labels of our triangle we have:
o2+a2=h2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h2=100ft2+289ft2
h=389ft2−−−−−√
→19.7ft
