Answer:
using π as 3.14: 20165.08 cubic inches
in terms of π: 6422π cubic inches
Step-by-step explanation:
» Concepts
The volume of a cylinder is how much space the cylinder can take inside of it. The formula to find this volume is πr²h, where r = radius and h = height. In addition, it's important to know that the radius is half the diameter.
» Application
We're given the radius as 13 inches (26/2 = 13), and the height is 38 inches. Now, we just have to plug in the values and simplify.
» Solution
Using π as 3.14:

standard deviation of 0.03 in. In a bag containing 120 nails, how many nails are between 4.97
in. long and 5.03 in. long?
ut 57 nails
out 60 nails
out 82 nail
Answer:
82 nails
Step-by-step explanation:
4.97 and 5.03 are both one standard deviation from the mean...
z scores . 8413 and .1587
.8413 - .1587 = .6826 or 68.26 % of the nails are in this range
68.26 % * 120 = ~82 nails

evaluate the following
a) 4!=
b) 0!=
c) 2! + 3!=
d) 3! x 4!
e) 10! / 7!
Answer:
See below for answers and explanations
Step-by-step explanation:
4! = 4*3*2*1 = 24
0! = 1
2! + 3! = 2*1 + 3*2*1 = 2 + 6 = 8
3! * 4! = 3*2*1 * 4*3*2*1 = 6 * 24 = 144
10! / 7! = 10*9*8*7*6*5*4*3*2*1 / 7*6*5*4*3*2*1 = 10*9*8 / 1 = 720

write the above equation in the form of y = g(x).
⇒ y = (0.5)x + 3 – 4
Now, we convert the equation into y = mx + c form.
⇒ y = (0.5)x - 1
Here, we see that m = slope = 0.5, and c = y-intercept = -1.
Hence, the graph of g(x) = (0.5)x + 3 – 4 is a straight line with slope = 1/2 and y-intercept = -1.

Answer:
a = 12
Step-by-step explanation:
Pythagoras’ Theorem
a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
From inspection of the triangle:
leg a = aleg b = 9hypotenuse c = 15Substituting these values into the formula and solving for b:
⇒ a² + 9² = 15²
⇒ a² + 81 = 225
Subtract 81 from both sides:
⇒ a² + 81 - 81 = 225 - 81
⇒ a² = 144
Square root both sides:
⇒ √(a²) = √(144)
⇒ a = 12

give two coterminal angles (one positive and one negative) and the reference angle. 290
The coterminal angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.
What is coterminal angles?Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have an angle:
290 degree
To find the coterminal angle, add and subtract 360 degree in the angle 290 degree.
Coterminal angle = 290 + 360 = 650 degree
= 290 - 360 = -70 degree
Reference angle = 360 - 290 = 70 degree
Thus, the coterminal angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.

I need help on 3 and 4
Answer:
Step-by-step explanation:
Parallel lines and transversal:Linear pair: When the uncommon arms of two adjacent angles form a straight line, the adjacent angles are called linear pair and they add upto 180
3) ∠3 + ∠2 = 180
65 + ∠2 = 180
∠2 = 180 - 65
∠2 = 115°When parallel lines are intersected by transversal, alternate exterior angles are congruent.
a // b and d is transversal.
∠5 = ∠11
∠5 = 100°
When parallel lines are intersected by transversal, the alternate interior angles are congruent.
a // b and c is transversal
m∠13 = ∠3
∠13 = 65°
4) ∠3 & ∠14 are co-interior angles. Co-interior angles are supplementary.
∠3 + ∠14 = 180
65 + ∠14 = 180
∠14 = 180 - 65
∠14 = 115°
∠5 + ∠8 = 180 {Linear pair}
100 + ∠8 = 180
∠8 = 180 - 100
∠8= 80
∠9 = ∠11 {vertically opposite angles are congruent}
∠9 = 100
∠ 3 + ∠14 + ∠ 8 + ∠9 = 65 + 115 + 80 + 100

The graphed inequality can be written as:
y < -(4/3)*x + 5
How to find the inequality?
At first, we can notice two things, the shaded region is below the line, and the line is a dashed line, so we know that the inequality will be:
y < linear equation.
The linear equation is something like:
y = a*x + b
By looking at the graph, we can see that the line passes through (0, 5) and (3, 1).
So the y-intercept is 5.
And the slope is:
a = (1 - 5)/(3 - 0) = -4/3
So the linear equation is:
y = -(4/3)*x + 5
And the inequality is:
y < -(4/3)*x + 5

A 0.25 kg baseball is in contact with a bat for 0.0075 s and exerts a force of 18,500 n. what impulse is delivered to the ball? 33 kg • meters per second. 140 kg • meters per second. 4600 kg • meters per second. 74,000 kg • meters per second.
The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
What is Impulse?An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
Mass of baseball m = 0.25kgTime of contact t = 0.0075sForce exerted F = 18500N = 18500kgm/s²Impulse ΔP = ?We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s

PLS PLS HELP ME
The mean absolute deviation for the Jumping Jackrabbits was of 3.8, which was lower than the 6.8 for the Leaping Lizards, hence they had more consistent scores.
What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation(MAD) of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean.For the Jumping Jackrabbits and the Leaping Lizards, the mean and the MAD are given as follows:
M = (70 + 65 + 72 + 80 + 73)/5 = 72
MAD = (|70 - 72| + |65 - 72| + |72 - 72| + |80 - 72| + |73 - 72|)/5 = 3.6.
M = (61 + 47 + 70 + 63 + 54)/5 = 59
MAD = (|61 - 59| + |47 - 59| + |70 - 59| + |63 - 59| + |54 - 59|)/5 = 6.8.

one of the exterior Angles of a triangle is 125°and the interior opposite angles are in the ratio 2:3 please find the Angles of the triangle
Answer:
Angles of the triangles are 55° , 50° , 75°
Step-by-step explanation:
Exterior angle property of triangle:The exterior angle of a triangle equals the sum of opposite interior angles.
Ratio of interior opposite angle = 2 : 3
Interior opposite angles are 2x , 3x
2x + 3x = 125
5x = 125
x = 125/5
[tex]\boxed{x = 25}[/tex]
2x = 2*25 = 50°
3x = 3*25 = 75°
Let the third angle of the triangle = y
Sum of all angles of triangle = 180
50 + 75 + y = 180
125 + y = 180
y = 180 - 125
y = 55°
Angles of the triangles are 55° , 50° , 75°
