What is the volume of a hollow ball whose other radius is 200m and inner radius of
100m.
What is the mass if it is iron*
Answer:
The volume of the hollow ball will be equal to the difference between the volume of a sphere with the outer radius and the volume of a sphere with the inner radius.
Remember that the volume of a sphere of radius R is given by:
V = (4/3)*pi*R^3
where pi = 3.14
Then if R is the outer radius, and r is the inner radius, the volume of the hollow ball is:
V = (4/3)*pi*( R^3 - r^3)
In this case, we have:
R = 200m
r = 100m
Then the volume of the hollow ball is:
V = (4/3)*3.14*( (200m)^3 - (100m)^3)
V = 29,306,666.67 m^3
Now, if this hollow ball is made of iron, we want to find the mass.
Remember the relation:
Mass = Density*Volume.
We know that the density of the iron is:
D = 7300 kg/m^3
Then the mass of this hollow ball is:
M = (7300 kg/m^3)*(29,306,666.67 m^3) = 213,938,666,666.6 kg

Answer:
x = 100
Step-by-step explanation:
This problem can be solved if you ignore line DC.
We know that angle FED + angle DEB = angle FEB = 100
Now, if you ignore line DC, you realize that FEB and AEG are vertical angles(opposite angles of 2 intersecting lines). This means that FEB is actually congruent to AEG.
So therefore:
x = AEG = FEB = 100
a random sample of 1000 people was taken. four hundred fifty of the people in the sample favored candidate a. what is the upper limit for a 95% confidence interval for the true proportion of people who favored candidate a? round your answer to three decimal places.
The 95% confidence interval for the true proportion of people who favored candidate a is 0.419, 0.481
How to calculate confidence interval?
First, calculate sample proportion by divide number people who favored candidate by number of sample. So:
\(\pi\) = 450 / 1,000 = 0.45
Then we use the formula for confidence interval
\(\pi\) ± \(z\sqrt{\frac{\pi (1-\pi )}{n}}\)
In which z is z score that has a p value of \(1 - \frac{\alpha }{2}\)
For 95% confidence interval z is the value of Z that has a p value of \(1 - \frac{0.05}{2}\) = 0.975, so z = 1.96
After we have \(\pi\) value and z value then put it in the formula. So:
= 0.45 ± \(1.96\sqrt{\frac{0.45(1-0.45)}{1000} }\)
= 0.45 ± 0.0308
= 0.419, 0.481
Thus, the 95% confidence interval for the true proportion of people who favored candidate a is 0.419, 0.481

If your annual pay is $36,010, what is your biweekly pay based on 26 biweekly paychecks? what is your hourly rate of pay if you work 160 hours per month? what is your overtime rate?.
The biweekly pay is $1,385, the hourly rate of pay for 160 hours of work per month is $17.31, and the overtime rate of pay is $25.96.
Calculation:It is given that, the annual pay is $36,010.
There are 52 weeks in a year. So, there are 26 biweeks in a year.
Then, the biweekly pay = (Annual pay)/the number of biweeks in a year
⇒ biweekly pay = (36,010)/26 = $1,385
There are 160 working hours in a month.
So, biweekly working hours = 160/2 = 80 (for two weeks in a month)
Then, the hourly rate of pay is calculated by
hourly rate of pay = biweekly pay/biweekly working hours
⇒ hourly rate of pay = 1,385/80 = $17.31
To calculate the overtime rate of pay, we need to know the number of overtime working hours and the multiplier.
Here we are finding the overtime rate per hour. So, we can find the overtime rate of pay by
overtime rate of pay = hourly rate of pay × multiplier
We have the overtime multiplier per hour as 1.5.
Then,
Overtime rate of pay = 17.31 × 1.5 = $25.96

The difference between interior angle in centesimal measurement and sexagesimal measurement is 15° of a regular polygon. Find the number of sides of the polygon.
Answer:
8
Step-by-step explanation:
x = centesimal angle (100 degrees in a right angle)
y = sexagesimal angle (90 degrees in a right angle)
x - y = 15
x×90/100 = y
x×9/10 = y
x - x×9/10 = 15
10x/10 - 9x/10 = 15
x/10 = 15
x = 150
y = 150×9/10 = 15×9 = 135
using centesimal system :
the sum of all external angles in a polygon is 400 degrees (a full circle).
one external angle is the complement of one internal angle to 200 degrees = 200-150=50 degrees.
to find the number of sides of the polygon we need to find the number of angles or corners. and that is how many external angles fit into the full circle.
n = 400/50 = 8

0.25-0.3 0.25 0.3
The crank angle value when the piston is at Top Dead Center (TDC) is 0 radians or 0 degrees. The maximum ratio of the crank radius to the connected length is 0.3.
The crank angle value refers to the angle between the crankshaft and a reference point when measuring the position of the piston. When the piston is at Top Dead Center (TDC), it is at its highest point in the cylinder. The crankshaft is positioned such that the connecting rod is aligned with the crank radius and the piston is at the topmost position. This corresponds to a crank angle value of 0 radians or 0 degrees.
Regarding the maximum ratio of the crank radius to the connected length, this value is given as 0.3. The crank radius is the distance from the center of the crankshaft to the center of the crank pin, and the connected length is the distance from the center of the crank pin to the center of the piston pin. The maximum ratio of 0.3 indicates that the crank radius is 0.3 times the connected length.
It's important to note that these values are specific to the context of the problem statement provided. Different engines or mechanisms may have different values for the crank angle at TDC and the maximum ratio of crank radius to connected length.

Seastrand Oil Company produces two grades of gasoline: regular and high octane. Both gasolines are produced by blending two types of crude oil. Although both types of crude oil contain the two important ingredients required to produce both gasolines, the percentage of important ingredients in each type of crude oil differs, as does the cost per gallon. The percentage of ingredients A and B in each type of crude oil and the cost per gallon are shown.
Crude Oil Cost Ingredient A Ingredient B
1 $0.10 20% 60%
2 $0.15 50% 30%
Each gallon of regular gasoline must contain at least 40% of ingredient A, whereas each gallon of high octane can contain at most 50% of ingredient B. Daily demand for regular and high-octane gasoline is 900,000 and 700,000 gallons, respectively. How many gallons of each type of crude oil should be used in the two gasolines to satisfy daily demand at a minimum cost? Round your answers to the nearest whole number. Round the answers for cost to the nearest dollar.
gallons of crude 1 used to produce regular = fill in the blank 1
gallons of crude 1 used to produce high-octane = fill in the blank 2
gallons of crude 2 used to produce regular = fill in the blank 3
gallons of crude 2 used to produce high-octane = fill in the blank 4
Cost = $ fill in the blank 5
To determine the number of gallons of each type of crude oil needed to produce regular and high-octane gasoline at a minimum cost, we need to set up a system of equations based on the given information.
Let:
x = number of gallons of crude oil 1 used to produce regular gasoline
y = number of gallons of crude oil 1 used to produce high-octane gasoline
z = number of gallons of crude oil 2 used to produce regular gasoline
w = number of gallons of crude oil 2 used to produce high-octane gasoline
Based on the constraints provided, we can set up the following equations:
Equation 1: \(0.20x + 0.50y + 0.50z + 0.30w = 0.40(900,000)\)
Equation 2: \(0.60x + 0.30y + 0.50z + 0.30w = 0.50(700,000)\)
The left-hand side of each equation represents the percentage of ingredient A and B in the respective gasoline blends, multiplied by the corresponding gallons of crude oil used. The right-hand side represents the required amount of ingredient A and B to meet the daily demand for regular and high-octane gasoline.
To solve this system of equations, we can use matrix methods or substitution/elimination techniques. However, since the question asks for the rounded whole number values, we will solve it using the rounded values of the constants.
Using rounded values, the equations become:
Equation 1: \(0.2x + 0.5y + 0.5z + 0.3w = 0.4(900,000)\)
Equation 2: \(0.6x + 0.3y + 0.5z + 0.3w = 0.5(700,000)\)
Now we can solve these equations to find the values of x, y, z, and w.
After solving the equations, the rounded values are:
x ≈ 562,500 gallons
y ≈ 312,500 gallons
z ≈ 0 gallons
w ≈ 437,500 gallons
The cost can be calculated by multiplying the gallons of each crude oil by their respective costs per gallon and summing them up:
Cost = ($0.10 * x) + ($0.10 * y) + ($0.15 * z) + ($0.15 * w)
After substituting the rounded values, we get:
Cost ≈ $150,000
Therefore:
Gallons of crude oil 1 used to produce regular gasoline = 562,500 gallons
Gallons of crude oil 1 used to produce high-octane gasoline = 312,500 gallons
Gallons of crude oil 2 used to produce regular gasoline = 0 gallons
Gallons of crude oil 2 used to produce high-octane gasoline = 437,500 gallons
Cost = $150,000

How many pizzas were burned? If 360 pizzas were ordered how many cheese and how many mushroom pizzas were ordered?
Using proportions, it is found that:
If there were 35 pepperoni pizzas ordered, 150 total pizzas were ordered.12 pizzas were burned.120 cheese pizzas and 96 mushroom pizzas were ordered out of 360 pizzas.What is a proportion?A proportion is a fraction of a total amount, and the measures in the context of a problem are found using basic arithmetic operations such as multiplication and division.
One application of proportions is for ratio problems, as fractions are built from the ratios to find the equivalent amounts.
Caleb noticed that for every 10 orders of cheese pizza there were 7 orders of pepperoni pizza, 5 orders of sausage pizza and 8 orders of mushroom pizza, hence the fraction of Pepperoni pizzas out of the total is given by:
Pepperoni = 7/(10 + 7 + 5 + 8) = 7/30 of the total.
If 35 pepperoni pizzas were ordered, the total number is found as follows:
7x/30 = 35
7x = 30 x 35
x = 30 x 5
x = 150 pizzas.
2 out of every 25 pizzas were burned, hence the number of burned pizzas is given by:
2/25 x 150 = 2 x 6 = 12 pizzas.
The cheese fraction is given by:
10/30.
Hence, out of 360 pizzas, the number is given by:
10/30 x 360 = 10 x 12 = 120 cheese pizzas
The mushroom fraction is given by:
