The cylinder on a tanker truck is 27 feet long and has a radius of five feet. What is the volume of the tank?
Answers
Answer:
2120.85 ft^3
Step-by-step explanation:
Given data
Height h= 27 ft
Radius r= 5 ft
The volume of a cylinder is given as
V= πr^2h
Substitue
V= 3.142*5^2*27
V= 3.142*25*27
V= 2120.85 ft^3
Hence the volume is 2120.85 ft^3
Matilda recently took a statistics quiz in her math class. in one question, 45 of 900 visitors at a local craft show were surveyed about the cost of admission to the show. Matilda incorrectly stated that the sample in this situation was represented by 900 visitors at the craft show.
a. what is Matilda's error?
b. what is the actual sample?
Answers
Answer:
A. Her error was that she thought that they were surveying the whole town so 900 would be the sample.
B. The actual sample is 45.
Step-by-step explanation:
The actual sample is 45 because 45 people out of the 900 visitors (population) were surveyed.

In an 80/20 mortgage, what is the first mortgage used for
A. 80% down payment
B. 20% interest rate
C. 20% down payment
D. 80% of the home’s value
Answers
============================================================
Explanation:
As you probably expect, the first number 80 refers to the percentage the first loan covers. If the house is say $100,000, then the first loan is $80,000 while the second loan is the remaining $20,000.
An 80/20 mortgage, or similar, will have two monthly payments because you are getting two mortgages bundled together. Usually you should pay a down payment, though it may likely depend on your credit history. Those with good credit will pay less or no down payment, compared to those with worse credit will have to pay more down payment. A good rule of thumb is that 20% of the home's value is made as down payment, though this isn't what the "20" in "80/20" is referring to.
An 80% down payment is extremely high and unreasonable. Not many people have that kind of money laying around. A similar story applies to a 20% interest rate which is incredibly large for a mortgage rate (typically they are in the single digits such as 3%).
A circles diameter is 12 inches what is the circles circumference using 3.14 rounded to the nearest tenth
Answers
Answer:
[tex]37.7in.[/tex]
Step-by-step explanation:
The circumference of a circle is: [tex]C=2\pi r[/tex]
However, the question wants us to use 3.14 instead of [tex]\pi[/tex].
We are given 12 inches as the diameter of the circle.
We want the radius, which is half of the diameter.
The radius of the circle is 6 inches.
Now that we have the radius, we plug and chug.
[tex]C=2*3.14*6in.\\C=6.28*6in.\\C=37.68in.\\[/tex]
However, the question wants us to round the answer to the nearest tenth.
Therefore, the new answer is: [tex]37.7in.[/tex]
What is the y-intercept of the equation of the line that is perpendicular to the line and passes through the point (15,-5)?
Answers
Answer:
hi
Step-by-step explanation:
First of all let’s find out the slope of the line y = x +10
As, we know the equation y= mx + c . So comparing the given equation with the general equation we get, m = 1
Now, we know that the product of two perpendicular lines is -1.
Thus, mn = -1 (considering slope of the second line as n)
Putting the value of m we get , n = -1
Now , y+5= -1( x -15) i.e y=-x + 10
if we compare again with the general equation then we find that.
The y intercept of the required equation is 10.

The volume of the prism is 72 cubic feet. Find the missing height of the triangular prism, and the surface area.
Answers
Answer:
h = 12
surface area = 192
Step-by-step explanation:
Volume of this prism = 72
The base triangle has an area of B * h/2
The base = 6
The height in red = 2
Area = 1/2 * 6 * 2
Area = 6 ft^2
The volume = B * h = 72
The base = 6
6* h = 72
h = 72/6
h = 12
The surface area = 2 triangles + the rectangle face closest to us + the rectangular face whose width is 4 + rectangular face whose with is 5
The surface area = 2 * 6 + 6* 12 + 4*12 + 5 * 12
The surface area = 12 + 72 + 48 + 60
The surface area = 192 square feet.

Emily the blacksmith blends one alloy of silver that is 45% silver and another that is 95% silver. To the nearest ton, how much of each alloy is needed to make 139 tons of a 70% silver alloy?
please answer
Answers
Answer:
69.5 tons of Alloy 1 (of 45% silver) and 69.5 tons of Alloy 2 (of 95% silver) is needed to make 139 tons of 75% silver alloy
Step-by-step explanation:
Given
[tex]Alloy\ 1 = 45\%[/tex]
[tex]Alloy\ 2 = 95\%[/tex]
Required
How much of each alloy is needed for 70% silver alloy 139 tons
Let the amount of alloy 1 needed be x and the amount of 2 needed by y.
So:
[tex]x + y = 139[/tex]
Make y the subject
[tex]y = 139 - x[/tex]
The percentage of each needed is represented as:
[tex]45\% * x + 95\% * y = 139[/tex]
[tex]45\% * x + 95\% * y = 70\% * 139[/tex]
[tex]0.45x + 0.95y = 0.70 * 139[/tex]
[tex]0.45x + 0.95y = 97.3[/tex]
Substitute 139 - x for y in the above equations
[tex]0.45x + 0.95*(139-x) = 97.3[/tex]
[tex]0.45x + 0.95*139-0.95*x = 97.3[/tex]
[tex]0.45x + 132.05-0.95x = 97.3[/tex]
Collect Like Terms
[tex]0.45x -0.95x = 97.3-132.05[/tex]
[tex]-0.50x = -34.75[/tex]
Make x the subject
[tex]x = \frac{-34.75}{-0.50}[/tex]
[tex]x = 69.5[/tex]
Recall that:
[tex]y = 139 - x[/tex]
[tex]y = 139 - 69.5[/tex]
[tex]y = 69.5[/tex]
This implies that:
69.5 tons of Alloy 1 (of 45% silver) and 69.5 tons of Alloy 2 (of 95% silver) is needed to make 139 tons of 75% silver alloy

Step-by-step explanation:
Leon constructed a point P that divides the directed segment from A to B in the ratio 2 to 1. Chelsea constructed a point Q that divides the directed segment from B to A in the ratio 1 to 2. How are points P and Q related? Explain.
Points P and Q are...
A.) two units apart. B.) the same point. C.) one unit apart.
Point P is ___ of the distance from A to B. [ A.) 2/3 B.) 1/2. C.) 1/3. ]
Point Q is of the distance from B to A. [ A.)1/3 B.). 1/2 C.)2/3. ]
The means the points lielocation along the line segment.
[ A.) At the same B.)At a different
Solution:
Since point P is divides the segment from A to B in the ratio 2 to 1 therefore:
P = 2/3 of the distance from A to B.
Since point Q is divides the segment from B to A in the ratio 1 to 2, therefore:
Q = 1/3 of the distance from B to A
2/3 of the distance from A to B = 1/3 of the distance from B to A
Therefore point P and point Q lie along the same line segment from A to B (or B to A) and the points P and Q are at the same point,

it only works for right triangles, c is the hypotenuse, a and b are the legs
so to find b we plug in the info we have!
7.8^2+b^2=17.8^2
next we simplify:
60.84+b^2= 316.84
subtract 60.84 from both sides to isolate the variable:
b^2=256
square root both sides
b=16

Write down the correct type of angle for angles A to E.
Answers
Answer:
Angle A- Obtuse angle
Angle B- Right angle
Angle C- Reflex angle
Angle D- Reflex angle
Angle E- Acute angle
Angle A is Obtuse angle, Angle B is Right angle, Angle C is Reflex angle, Angle D is Reflex angle and Angle E is Acute angle
What are Angles?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
Obtuse angle is any angle greater than 90°
A right angle is an angle measuring exactly 90°
A reflex angle is an angle that is more than 180 degrees and less than 360 degrees.
Any angle that measures greater than 0° and less than 90° is called an acute angle.
By the definitions of these the angles are
Angle A- Obtuse angle
Angle B- Right angle
Angle C- Reflex angle
Angle D- Reflex angle
Angle E- Acute angle
Hence, Angle A is Obtuse angle, Angle B is Right angle, Angle C is Reflex angle, Angle D is Reflex angle and Angle E is Acute angle

A curious statistics student cannot get enough statistics, so he decides to analyze the percentage of students sleeping in his statistics class. He discovers that of the 30 students in his class, 47% of the students were asleep at some point during the class period. Assuming the 30 students is less than 10% of all the students taking statistics in his school, and assuming the 30 students in the class were randomly assigned to the class, what model would he use to analyze the percentage of sleeping statistics students
Answers
Answer:

Step-by-step explanation:
Options to the question are "a) N(.30, .10), b) N(.30, .09). c) N(.47, .09), d) N(.47, .008), e) N(.30, .008)"
Pο = 47% = 0.47
n = 30
Mean = Pο = 0.47
S.D = Pο(1-Pο) / n
S.D = 0.47 * 0.53 / 30
S.D = 0.09
Thus, the percentage of sleeping statistics of students follows a Normal distribution with mean = 0.47 and S..D = 0.09
