Answer:
1. x = 1.5 rpm
2. x ≈ 0.8182 mi/hr
3. x = 6.6 feet
4. x = 4224 rpm
5. x = 390 rpm
Step-by-step explanation:
The relationship between angular speed and linear speed is given as follows;
Angular speed, ω = Linear speed, v/(Radius, r)
Therefore, we have;
1. When v = 12 cm/min = r = 8 cm , ω = 12/8 = 1.5 rpm
2. When, ω = 4 rpm, and r = 18 feet, v = 4 × 18 = 72 feet/min ≈ 0.8182 mi/hr
3. When, ω = 800 rpm, and v = 60 mi/hr = 1 mi/min, r = x = 1/800 miles = 6.6 feet
4. When v = 60 mi/hr = 63,360 mi/min, r = 15 in , ω = 63360/15 = 4224 rpm
5. When v = 13 in/sec = 780 in/min, r = 2 in, ω = 780/2 = 390 rpm

|5k-8| / 10 = 2
|5k-8| / 10 is a fraction btw
Answers
Answer:
K is -12/5
k is also 28/5
Step-by-step explanation:
Here, we want to solve the equation
|5k-8| = 10(2)
5k-8 = 20
5k = 20 + 8
5k = 28
k = 28/5
or
5k-8 = -20
5k = -20 + 8
5k = -12
k = -12/5
Three partners x,y and z contribute an amount of ksh 1400000 for an investment .The profit from the investment is to be shared based on the contribution of each.A profit of ksh 250000 after one month.If x got sh 60000, y got 110000 and the remainder was Z .Calculate the ratio of the contribution
Answers
Answer:
The ratio of the contribution x:y:z is 6:8:11
Step-by-step explanation:
Firstly, we need to know the amount in which Z got
That will be 250,000-x-y
= 250,000- 60,000 - 110,000 = 80,000
So the ratio of the contribution in x:y:z will be;
60,000:110,000:80,000
= 6:11:8

Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11 A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10 How much does a liter of milk cost, and how much does a loaf of bread cost?
Answers
Answer:
A liter of milk cost $0.75 and a loaf of bread cost $1.75
Step-by-step explanation:
Let the liters of milk by represented by m
Let the loaves of bread by represented by b
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11
3m + 5b = 11...... Equation 1
A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10
4m + 4b = 10.... Equation 2
Combining the Equations
3m + 5b = 11...... Equation 1
4m + 4b = 10.... Equation 2
We solve using the Elimination method
Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m
12m + 20b = 44..... Equation 3
12m + 12b = 30....... Equation 4
Substract Equation 4 from Equation 3
8b = 14
b = 14/8
b = $1.75
Solving for m
3m + 5b = 11...... Equation 1
3m + 5($1.75) = 11
3m + $8.75 = $11
3m = $11 -$ 8.75
3m =$ 2.25
m =$ 2.25/3
m = $0.75
Therefore,
a liter of milk cost $0.75 and a loaf of bread cost $1.75

There is a spinner with 12 equal areas, numbered 1 through 12. If the spinner is spun
one time, what is the probability that the result is a multiple of 5 and a multiple of 2?
Answers
Answer:
1/12
Step-by-step explanation:
There is only number between 1 and 12 that is both a multiple of 5 and 2, that being 10. 10 has an equal chance out of all the other numbers that can be spun, and there are 12 numbers, so 10 has a 1/12 chance of being spun.
