Anna had a solid wooden dowel with a length of 12 inches and a diameter of 1 inch, as shown below. She cut a two-inch portion out of the dowel as indicated. What was the volume, to the nearest tenth of a cubic inch, of the portion of the dowel that Anna cut out?
Answers
Answer:
Volume of the portion = 1.6 cubic inches
Step-by-step explanation:
Since, wooden dowel is in the shape of a cylinder,
Formula to be used to find the volume of the part Anna has cut from the dowel will be,
Volume = πr²h
Where r = radius of the cylinder or part of the wooden dowel
h = length of the portion
By substituting the values in the formula,
Volume = π(0.5)²(2)
= 0.5π
= 1.57 in³ ≈ 1.6 cubic inch
Therefore, volume of the portion will be 1.6 in³.

It is about 30,000 light years from our solar system to the center of the milky way Galaxy. the solar system revolves around the center of the milky way with an angular velocity of about 2.6 * 10^-8 radians per year. what distance does the solar system travel in its orbit each year?
The solar system travels about [] light years each year.
Given that a light year is about 5.88 * 10^12 miles, how fast is the solar system circling the center of the Galaxy in miles per hour? Found your answer to the nearest ten thousand.
The solar system is circling the center of the galaxy at about [] mi/hr.
Answers
a. The solar system travels about 188495.56 light years each year.
b. the solar system is circling the center of the galaxy at about 520000 mi/hr
a. Distance solar system travels each year.
The solar system travels about 188495.56 light years each year.
Since the distance the solar system travel around the milky way is a circular orbit. The distance travelled is the circumference of a circle.
So, the circumference C = 2πr where
r = radius of circle = distance of solar system from center of milky wat = 30000 light yearsSo, C = 2πr
= 2π × 30000 light years
= 60000π light years
= 188495.56 light years
So, the solar system travels about 188495.56 light years each year.
b. Speed of solar systemThe solar system is circling the center of the galaxy at about 520000 mi/hr
The speed of the solar system circling the milky way is given by v = rω where
r = radius of orbit = 30000 light years = 30000 × 5.88 × 10¹² miles = 1.764 × 10¹⁷ miles and ω = angular velocity of solar system = 2.6 × 10⁻⁸ radians per year = 2.6 × 10⁻⁸ radians per year × 1year/365 days × 1 day/24 hours = 2.6 × 10⁻⁸ radians/8760 hour = 2.97 × 10⁻¹² radians per hourSo, substituting the values of the variables into the equation, we have
v = rω
v = 1.764 × 10¹⁷ miles × 2.97 × 10⁻¹² radians per hour
v = 5.23908 × 10⁵ miles/hour
v = 523908 miles/hour
v ≅ 520000 mi/hr to the nearest ten thousand
So, the solar system is circling the center of the galaxy at about 520000 mi/hr

Jim just found a job with a take-home pay of $1,950 per month. He must pay $1,200 for rent and $200 for groceries each month. He also spends $200 per month on transportation. If he budgets $50 each month for clothing, $100 for restaurants and $50 for everything else, how long will it take him to put together emergency savings of $1,500?
Answers
Add all his expenses together:
1200 + 200 + 200 + 50 + 100 + 50 = $1,800
Subtract his expenses from his pay:
1950 - 1800 = 150
Divide how much the emergency savings is by the amount left over per month:
1500/150 = 10
it will take 10 months

A tank contains 50 liters of oil at time t = 4 hours. Oil is being pumped into the tank at a rate R(t) where R(t) is measured in liters per hour, and t is measured in hours. Selected values of R(t) are given in the table above. Using a right Riemann sum with three subintervals and data from the table, what is the approximation of the number of liters of oil that are in the tank at time t = 15 hours?
Answers
The volume of oil inside the tank at [tex]t = 15\,h[/tex] is approximately 66.556 liters.
How to estimate volume capacity by Riemann sumIn this question we must estimate the volume by Riemann sum, which consist in sum of all areas of the trapezoids of equal width in the volume rate versus time graph. The right Riemann sum with three intervals for this case is described below:
[tex]Q = \Sigma \limits_{i=0}^{2} \left\{R_{i}+\frac{1}{2}\cdot [R_{i+1}-R_{i}] \right\}\cdot \Delta t[/tex]
[tex]Q = \left[6.5+\frac{1}{2}\cdot (6.2-6.5) \right]\cdot (3.667)+\left[6.2+\frac{1}{2}\cdot (5.9-6.2)\right]\cdot (3.667) +\left[5.9+\frac{1}{2}\cdot (5.6-5.9) \right]\cdot (3.667)[/tex]
[tex]Q \approx 66.556\,L[/tex]
The volume of oil inside the tank at [tex]t = 15\,h[/tex] is approximately 66.556 liters. [tex]\blacksquare[/tex]
Remark
The table of the volume rate versus time is missing, all missing values of the table are included below:
[tex]R(4) = 6.5\,\frac{L}{h}[/tex], [tex]R(7.667) = 6.2\,\frac{L}{h}[/tex], [tex]R(11.333) = 5.9\,\frac{L}{h}[/tex], [tex]R(15) = 5.6\,\frac{L}{h}[/tex]

solve the following equation for g: 2(g - h)=b + 4
Answers
Answer:
The steps to do this :
[tex]2(g - h) = b + 4[/tex]
[tex]g - h = \frac{b + 4}{2} [/tex]
[tex]g = \frac{b + 4}{2} + h[/tex]
[tex]g = \frac{b}{2} + \frac{4}{2} + h[/tex]
[tex]g = \frac{b}{2} + 2 + h[/tex]
2(g - h)=b + 4
Use the distributive property on the left side:
2g - 2h = b +4
Add 2h to both sides:
2g = 2h + b + 4
Divide both sides by 2:
g = (2h + b + 4)/2
Simplify:
g = b/2 + 2 + h ( note the order of h, 2 and b/2 can be different)

Step-by-step explanation:
0.3
A. greater than 0.3
The Margin of error is 0.3 when assuming a 90% confidence level.
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
The formula for finding the MOE:
MOE = z score * s/√n
Where is the z score at the confidence interval
s is the standard deviation
n is the number of samples.
here, we have,
It is given that among 320 randomly selected airline travelers, the mean number of hours spent traveling per year is 24 hours and the standard deviation is 2.9.
It is required to find the margin of error when the confidence level is 90%.
We have in the question:
at 90% confidence interval = 1.645 (From the Z score table)
s = 2.9
n = 320
Put the above values in the formula, we get:
MOE = 0.2666
Rounding the nearest tenth:
MOE = 0.3
Thus, The Margin of error is 0.3 when assuming a 90% confidence level.
