Answer:
A. 4/15 and 0.26 repeating
Step-by-step explanation:
As we see in the long division, 4/15 is equal to 0.26666666666666666666666 (or. 0.26 repeating).
4/15
4 doesn't go into 15, so add a zero.
4.0/15
40 goes into 15 twice
40 - 30 is 10. 10 is less than 15 so add a 0.
4.00
100 goes into 15 6 times.
100 - 90 is 10. 10 is less than 15, so add a 0.
The 100 into 15 process repeats, so there's your answer.
Answer:
What if you have to push a heavy object up a ramp? Say, for example, you have to move a refrigerator. You want to go camping, and because you expect to catch plenty of fish, you decide to take your 100-kilogram refrigerator with you. The only catch is getting the refrigerator into your vehicle (see the figure). The refrigerator has to go up a 30-degree ramp that happens to have a static coefficient of friction with the refrigerator of 0.20 and a kinetic coefficient of friction of 0.15. The good news is that you have two friends to help you move the fridge. The bad news is that you can supply only 350 newtons of force each, so your friends panic.
The minimum force needed to push that refrigerator up the ramp has a magnitude Fpush, and it has to counter the component of the weight of the refrigerator acting along the ramp and the force due to friction.
The first step in this problem is to resolve the weight of the refrigerator into components parallel and perpendicular to the ramp. Take a look at the figure, which shows the refrigerator and the forces acting on it. The component of the weight of the refrigerator along the ramp is

Answer:
19:00
Step-by-step explanation:
because 12 would be 24 and minus 4 would be 20 witch means 8pm so it would 19 cause because 20 minus 1 equals 19
Answer:
Step-by-step explanation:
x^2 + 2x + 1 = 17
x^2 + 2x = 17 - 1
x^2 + 2x = 16
x^2 + 2x + 1 = 16 + 1
(x + 1)(x + 1) = 17
(x + 1)^2 = 17
x + 1 = sqrt 17
x = -1 (+ - ) sqrt 17
x = -1 + sqrt 17 or x = -1 - sqrt 17 <===
The easiest way to solve a problem like this is to cross multiply and solve
The problem gives us a ratio
2 pounds of granola = 3 pounds of raisins
which makes a ratio of
The other ratio is
? pounds of granola = 24 pounds of raisins
which makes a ratio of
To solve, set them equal to each other ...
Now we must cross multiply...
To cross multiply, we multiply
2 and 24 and we multiply
3 and x Now we have an equation to solve!
3x = 48 To solve and get your final answer, divide...
x = 
x = 16
You'll need 16 pounds of granola
