A five-speed bicycle has a chain linking the pedal sprocket to the gears on the rear wheel. The ratio of pedal turns to rear-wheel turns in first gear is 8 to 17. How many times in first gear does the rear wheel turn if the pedals turn 160 times?
9514 1404 393
Answer:
340
Step-by-step explanation:
Multiply each number in the ratio by 20:
pedal : wheel = 8 : 17 = 160 : 340
The rear wheel turns 340 times when the pedal turns 160 times.
__
Additional comment
As a reasonableness check, realize that 17 is just slightly more than 2 times 8. Then the number of rear wheel turns will be slightly more than 2 times 160.

A coin is tossed 12 times. What is the probability of obtaining five heads and seven tails?
Answer:
99/512 = 0.193359375
Step-by-step explanation:
Each sequence of 5 H's and 7 T's has probability of occurring equal to 1/2^12 (1 divided by 2 to the twelfth power).
Since the number of 5 H, 7 T sequences is equal to C(12,5) = the number of combinations of 12 things taken 5 at a time =
12 * 11 * 10 * 9 * 5 / (5 * 4 * 3 * 2 * 1) =
792,
we have that the probability of obtaining 5 H's and 7 T's =
the sum of the probabilities of all of the sequences =
1/2^12 + 1/2^12 + 1/2^12 + . . . + 1/2^12, 792 times =
792(1/2^12) =
99 / 2^9 =
99 /512 =

Convert grams to kilograms by completing the number sentences.
4,567 grams= _______ x_______
=_______x________
=_______x________
Answer:
0.004567 kilograms
Step-by-step explanation:
4.567 grams=4.567÷1000=0.004567
becouse 1 kilogram = 1000grams
The conversion of 4,567 grams into kilograms will give the result of 0.004567 kilograms.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We need to Convert grams to kilograms by completing the number sentences.
Since, 1 kilogram = 1000 grams
4.567 grams = 4.567 ÷ 1000
4.567 grams = 0.004567
Therefore, the conversion of 4,567 grams into kilograms will give the result of 0.004567 kilograms.

{ x - 3y= -3 & x + y= 5 We are to use the graph to solve the given system of equations, then enter your solution below. I get how to draw the second equation but not the first. found slope of 1/3 & b=1. i dont understand how to graph this. I have tried different ways but keep getting it wrong.
Answer:
Solution: (3, 2)
Step-by-step explanation:
It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.
x - 3y = -3
-3y = -x - 3
Divide both sides by -3:
[tex]\frac{-3y}{-3} = \frac{-x - 3}{-3}[/tex]
y = 1/3x + 1
where slope = 1/3
y-intercept = 1
x + y = 5
Subtract x from both sides to isolate y:
x - x + y = - x + 5
y = -x + 5
where slope = -1
y-intercept, 5
I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, x - 3y = -3 is the blue line, while x + y = 5 is the green line. Their intersection occurs at point, (3, 2).
Therefore, the solution is (3, 2).

Step-by-step explanation:
The signs of the two terms are different. That will still be true of the factored form. If you factor out a minus sign, then the constant in parentheses becomes negative.

A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 151 feet per second from an initial height of 95 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation:
h = - 16t² + 151t +95
Answer:
Step-by-step explanation:
144 = -16t² + 151t + 95
0 = -16t² + 151t - 49
quadratic formula
t = (-151 ±√(151² - 4(-16)(-49))) / (2(-16))
t = (-151 ± 140.23195) / -32
t = 0.34 s
t = 9.10 s

The graph below is the function f(x)
Find lim x -> -1- f(x)=
As x approaches -1 from the left, the graph of f(x) leads you to the point (-1, 3), so the limit from the left is 3.
As x approaches -1 from the right, the graph leads to the point (-1, -3), so the limit from the right is -3.
The one-sided limits do not match, so the two-sided limit does not exist.
But f(x) is still defined at x = -1; this is indicated by the point (-1, -1). So f (-1) = -1.
We have found all the given limits for all the function.

pls change this to decimal number 1011111 base 2
===========================================================
Explanation:
Check out the table below. Each 1 and 0 corresponds to a power of 2. A 1 indicates that we'll add on that power of 2 while a 0 means we ignore it. We will add up the items in the second row that correspond to a "1" in the first row.
We get:
2^6+2^4+2^3+2^2+2^1+2^0 = 64+16+8+4+2+1 = 95
Effectively, we add nearly everything in the second row except for the 2^5 term.
Therefore, the number 1011111 base 2 is equivalent to 95 base 10.
