What is the volume, in cubic in, of a cylinder with a height of 20in and a base radius of 2in, to the nearest tenths place?
Answers
Answer:
251.2
Step-by-step explanation:
The formula for the volume of a cylinder is \(\pi r^2h\). Plugging in your measurements...
Height = 20 inches.
Radius = 2 inches.
The volume is \(\pi2^2h\).
Simplification...
\(\pi2^220 = \pi4(20)= 4\pi 20\).
\(\pi\) ≈ \(3.14\)
3.14 * 4 = 12.56
12.56*20 = 251.2
Problem No. 6 Tamsin is saving up for a smartwatch and puts all of her 50 cent and 20 cent coins in a jar each night. She thinks that she has saved enough and empties the 620 coins to count the money. 286 of the coins are 50 cent. If the cost of the smart watch is €230, how much more must she save to allow her buy the watch?
Answers
Answer: She must save €230 - €209.8 = €20.2 more to buy the watch.
Step-by-step explanation:
Tamsin has saved 286 * €0.50 = €143 from 50 cent coins.
The remaining coins are 620 - 286 = 334 which are 20 cent coins
So the total amount she has saved from 20 cent coins is 334 * €0.20 = €66.8
Therefore, the total amount she has saved is €143 + €66.8 = €209.8
So she must save €230 - €209.8 = €20.2 more to buy the watch.
Using a deck of 52 playing cards what are the odds against drawing a 6, 7, 8, or 9 
Answers
The odds against drawing a 6, 7, 8 or 9 in a deck of 52 cards are given as follows:
2.25 : 1.
What is a probability and what is an odd?A probability is given by the number of desired outcomes divided by the number of total outcomes.An odd is the number of desired outcomes divided by the number of non-desired outcomes.Each number in a set of 52 cards has 4 cards, hence the number of cards with 6, 7, 8 or 9 is given as follows:
4 x 4 = 16.
Then the number of cards without these numbers is given as follows:
52 - 16 = 36.
Meaning that the odds against drawing these numbers is given as follows:
36 : 16 = 2.25 : 1.

Answer:
Part A: 13440 cubic inches.
Part B: A - 2940 cubic inches.
Step-by-step explanation:
The volume of the box = 24x20x28 = 13440 cubic inches.
The problem tells us that his gift is 10,500 cubic inches. So subtract that from the volume of the box.

A sprinkler sprays water to cover a circular region of 90pi square feet. Find the diameter of the circle.
Answers
Answer:
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius. Since we know that the circular region has an area of 90π square feet, we can set this equal to the area formula and solve for r:
A = πr^2
90π = πr^2
90 = r^2
Taking the square root of both sides, we get:
r = √90
r = √(9 x 10)
r = 3√10
The diameter of the circle is equal to twice the radius, so we have:
d = 2r
d = 2(3√10)
d = 6√10
Therefore, the diameter of the circle is 6√10 feet.

students work per week in the student activities office is less than 17.5 hours. What is the restriction for the number of
hours that the fourth student can work?
Answers
Answer:
less than 18 hours
Step-by-step explanation:
You want the restriction on the fourth value such that the average of it and 17, 19, and 16 will be less than 17.5.
Average valueThe average of a set of numbers is their sum, divided by the number of numbers. The average of the four students' hours will be ...
(17 +19 +16 +h)/4 < 17.5 . . . . . . restriction on average hours
SolutionMultiplying by 4 gives ...
52 +h < 70
h < 18 . . . . . . . . subtract 52
The fourth student can work less than 18 hours.

The Slope-Intercept form of the equation of a line is:
\(y=mx+b\)Where "m" is the slope of the line and "b" is the y-intercept.
Knowing that:
\(\begin{gathered} f\mleft(-2\mright)=0 \\ f(6)=-4 \end{gathered}\)You can identify that the line passes through these points:
\(\begin{gathered} (-2,0) \\ (6,-4) \end{gathered}\)By definition, the value of "x" is zero when the line intersects the y-axis and the value of "y" is zero when the line intersects the x-axis.
To find the slope of a line you can use the following formula:
\(m=\frac{y_2-y_1}{x_2-x_1}\)In this case, you can set up that:
\(\begin{gathered} y_2=-4 \\ y_1=0 \\ x_2=6 \\ x_1=-2 \end{gathered}\)Then substituting values into the formula and evaluating, you get that the slope of the line is:
\(m=\frac{-4-0}{6-(-2)}=\frac{-4}{6+2}=\frac{-4}{8}=-\frac{1}{2}\)You can substitute the slope and the coordinates of the second point into the equation
\(y=mx+b\)and then solve for "b":
\(\begin{gathered} -4=-\frac{1}{2}(6)+b \\ \\ -4=-3+b \\ -4+3=b \\ b=-1 \end{gathered}\)Knowing "m" and "b", you can write the following equation of this line in Slope-Intercept form:
\(y=-\frac{1}{2}x-1\)Rewriting it with:
\(f(x)=y\)You get that the answer is:

A scientist begins with 50 milligrams of a radioactive substance that decays exponentially. After 40 hours, 25 mg of the substance remains. How many milligrams will remain after 59 hours? Round to the nearest milligram.
Answers
Based on the information given, the number of milligrams that will remain after 59 hours will be 13.125 milligrams.
Since after 40 hours, 25 mg of the substance has been removed, therefore, the rate per hour will be:
= 25/40 = 0.625.
The amount that will be removed in 59 hours will be:
= 59 × 0.625 = 36.875
The number of milligrams that will remain will be:
= 50 - 36.875 = 13.125 milligrams

explain the relationship between the legs and the hypotenuse of a right triangle.
Answers
Answer:
Step-by-step explanation:
a right triangle and hypotenuse consist of two legs. the two legs meet at a 90 degrees angle and the hypotenuse is the longest side of the right triangle
The relation between the legs and hypotenuse can be described by Pythagoras theorem.
What is Pythagoras theorem?Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².
A right angled triangle is given as follows,
Here, the hypotenuse is given as AC,
And, the legs are AB and BC respectively.
The relation between them can be given by Pythagoras theorem as follows,
AC² = AB² + BC²
Hence, the sum of the squares of the legs of a right triangle is equal to the square of its hypotenuse.
