A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angular speed of the wheel, in radians per second? Round your answer to the nearest hundredth.
Answer: 3,140 radians per minute.
Step-by-step explanation:
We know that the wheel does 500 revolutions per minute.
This is called the frequency of the wheel, and this is written as:
f = 500 rev/min = 500 RPM
The angular speed (or Angular velocity) is written as
ω = 2*pi*f
And this quantity is in radians/unit of time.
where pi = 3.14
then:
ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min
This means that the angular velocity (or angular speed) is 3,140 radians per minute.
Answer:
The answer is 52.36

f) One number is 78 more than
another. If you add 12 to tbe
smaller number, the result is 50.
What is the larger number?
Answer:
The larger number = 116
Step-by-step explanation:
Let the smaller number = x
Given that one number is 78 more than another, so
The larger number = x+78
Given that if we add 12 to the smaller number, the result is 50, so
[tex]x+12=50[/tex]
subtract 12 from both sides
[tex]x+12-12=50-12[/tex]
Simplify
[tex]x=38[/tex]
Therefore,
The smaller number = 38The larger number = x+78 = 38+78 = 116Thus, the larger number = 116

A party rental company has chairs and tables for rent. The total cost to rent 4 chairs and 8 tables is 89 . The total cost to rent 2 chairs and 3 tables is 34 . What is the cost to rent each chair and each table?
Answer:
Let C = cost to rent each chairLet T = cost to rent each table 4C + 8T = 732C + 3T = 28 Multiply the 2nd equation by (-2) and then add the equations together 4C + 8T = 73-4C - 6T = -56 2T = 17T = 17/2 = 8.5 Plug this in to the 1st equation to solve for C 4C + 8(17/2) = 734C + 68 = 734C = 5C = 5/4 = 1.25 So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50

Find the values of the variables in the parallelogram.
Step-by-step explanation:
We can find x very easily because the left and right sides are parallel,making the diagonal connecting them a transversal therefore x=33°
To find y we know that the sum of interior angles of a triangle is 180°
y+109°+33°=180°
y+142°=180°
y=38°
Now,
x+38°+z=180
33+38+z=180
z=180-71=109°

Answer:
Distributive Property = 5y+2(y+3)+2
combining like terms = 5y+2+6+2y
Commutative Property = 6y-y+2y+10-4+2
Step-by-step explanation:
The correct matching of the properties will be:
Distributive Property = 5y+2(y+3)+2
combining like terms = 5y+2+6+2y
Commutative Property = 6y-y+2y+10-4+2
Original expression: 5y + 2(y + 3) + 2
How to match the valueApply the distributive property by multiplying 2 to the terms inside the parentheses:
5y + 2y + 6 + 2
Combine like terms:
(5y + 2y) + (6 + 2)
7y + 8
Rearrange the terms using the commutative property:
(7y + 2y) + (6 + 2)
9y + 8 + 8
Simplifying further, we have:
9y + 16
Therefore, the simplified expression is 9y + 16.

A researcher is interested in consumer preferences among three brands of yogurt. A sample of 90 people is obtained,
and each individual is asked to taste each brand and then select his/her favorite. The resulting frequency data are as
follows:
Brand A
Brand B Brand C
37
21
32
Do the data indicate any significant preferences among the three brands? Test at the .05 level of significance.
State the null hypothesis (1 point), the expected frequency for each category (3 points), the value of chi-
square (4 points), the df (1 points), the critical value of chi-square (2 points), and the decision regarding
significance (1 points).
Answer:
Step-by-step explanation:
From the given information:
The null hypothesis: all three brands are equally likely to their expected value
The alternative hypothesis: preferences exist among the three brands i.e. at least one is different from the expected value.
The expected frequency = [tex]f_e[/tex]
The observed frequency = [tex]f_o[/tex]
[tex]f_e[/tex] [tex]f_o[/tex] [tex](f_o- f_e)^2[/tex] [tex]\dfrac{(f_o - f_e)^2}{f_e}[/tex]

[tex]X^2 = \sum\dfrac{(f_o-f_e)^2}{f_e} = 4.47[/tex]
Degree of freedom = [tex](n-1)[/tex]
= 3 -1
= 2
At ∝ = 0.05 and df = 2
The critical value [tex]X^2_{0.05, 2}= 5.99[/tex]
Decision rule:
Since the calculated chi-square is less than the critical value, we do not reject the null hypothesis.
Thus, the null is retained with a calculated chi-square value of 4.47 and a critical chi-square value of 5.99.

12) y = -7/5x - 18/5
13) y = 3/5x + 9/5
14) y = -2x - 3
Step-by-step explanation:
For this explanation, let's use the last problem as the example. You would use the formula y=mx+b. The first thing you would need to find would be the slope, or m. So, you would find the slope and conclude the answer is -2. After that, you would solve for b and get the answer. Hope this helped!

If the 8 men on a construction crew make up 40% of the entire crew, how many people are in
the crew?
Answer:
20
Step-by-step explanation:
Since 40% of the crew are men, which means n.40=8 n=8/.40 n=20 total number of crew 20 - 8=12 are women.
The number of people in the crew is 20.
Let the number of people in the crew be represented by x.
Therefore, 40% of x will be 8. This can then be written as:
40% of x = 8
40/100 × x = 8
0.4 × x = 8
0.4x = 8
Divide both side by 0.4
0.4x/0.4 = 8/0.4
x = 20
Therefore, the number of people in the crew is 20.

If AX:XB as AB:AC, find missing length
AX = 5, CB = 4, AC =6, find AB
Answer:
AB = 15 ÷ 2
Step-by-step explanation:
The computation of the AB is shown below;
Given that
AX : XB as AB : AC
AX = 5
XB = 4
AC = 6
AB = x
Based on the above information
We can write as
5 : 4 as to x : 6
ratios can be written as fractions
5 ÷ 4 = x ÷ 6
(4)(x) = (5)(6)
4x = 30
x = 30 ÷ 4
x = 15 ÷ 2
Hence, the AB = 15 ÷ 2
