Answer:
#1
Use Pythagorean:
c² = a² + b²Apply to given and find c:
c² = 5² + 12²c² = 169c = √169c = 13 cm#2
cos = adjacent / hypotenusecos A = b/ccos A = 10/12 = 5/6#3
Assumed θ is ∠A, this is not too clearWe have:
a = 12c = 13We know that:
tan A = a/bFind b:
b = √c² - a² = √13²-12² = √25 = 5So
tan A = 12/5#4
Given
sin A = 15/17We know that:
sin A = a/c, so a = 15 and c = 17tan A = a/bFind b:
b = √c² - a²= √17²-15²= √64 = 8So
tan A = a/b = 15/8#5
Given
cot θ = 7/24We know:
cot = adjacent / oppositesec = 1/cos = hypotenuse / adjacentFrom the cot we have:
adjacent = 7, opposite = 24Hypotenuse is:
√24² + 7² = √625 = 25So,

Step-by-step explanation:
Standard deviation (SD) measured the volatility or variability across a set of data. It is the measure of the spread of numbers in a data set from its mean value and can be represented using the sigma symbol (σ). The following algorithmic calculation tool makes it easy to quickly discover the mean, variance & SD of a data set.

Answer:
2.6
Step-by-step explanation:
To calculate standard deviation:
(1) Find the mean - 4.33
4 + 5 + 9 + 1 + 2 + 5 = 26 26 / 6 = 4.333... ≈ 4.33
(2) Subtract the mean from each value and square each result
[tex](4 - 4.33)^2 = 0.1089[/tex] [tex](5 - 4.33)^2 = 0.4489[/tex] [tex](9 - 4.33)^2 = 21.8089[/tex]
[tex](1 - 4.33)^2 = 11.0889[/tex] [tex](2 - 4.33)^2 = 5.4289[/tex] [tex](5 - 4.33)^2 = 0.4489[/tex]
(3) Find a new mean with the new values from the previous step
0.1089 + 0.4489 + 21.8089 + 11.0889 + 5.4289 + 0.4489 = 39.3334
39.3334 / 6 = 6.555566667
(4) Take the square root of the new mean.

The rules of a game allow a team to score either 2 points or 5 points, depending on the nature of the scoring play. If the final score between two teams was 34 to 29, and there were 18 scoring plays altogether, how many 5-point plays were there?
Answers
Answer:
9
Step-by-step explanation:
Given that :
Total Number of scorings (both Teams) = 18
Let :
x = number of 5 point score ; y = number of 2 point score
Total points scored = 34 + 29 = 63
x + y = 18 - - - (1)
5x + 2y = 63 - - (2)
From (1)
y = 18 - x
In (2) ; we have ;
5x + 2(18 - x) = 63
5x + 36 - 2x = 63
3x + 36 = 63
3x = 63 - 36
3x = 27
x = 9

Find the value of LM and LN if M is between L and N.
LM = 7x + 4, MN = 20, LN = 10x
Answers
Answer:
LM = 20
LN = 160/7
Step-by-step explanation:
If M is between L and N, then LM = MN
Given
LM = 7x + 4, MN = 20, LN = 10x
7x+4 = 20
7x = 20 - 4
7x = 16
x = 16/7
LM = 16/7(7) + 4
LM = 16 + 4
LM = 20
LN = 10x
LN = 10(16/7)
LN = 160/7

Step-by-step explanation:

25 is missing in the last step.
Option C is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
To complete the square, we add and subtract the square of half of the coefficient of x, i.e., (10/2)² = 25, inside the parentheses:
8(x²+ 10x + 25 - 25) = -5
Simplifying the expression inside the parentheses.
8(x + 5)² = 200
Dividing both sides by 8.
(x + 5)² = 25
Taking the square root of both sides.
x + 5 = ±5
Solving for x.
x = -10 or x = 0
Thus,
The missing number is 25.

using the image,find angle x and y
Answers
Answer:
x =55 degrees
y = 35 degrees
Step-by-step explanation:
We know that the distance from the center of the circle to the circumference is the radius
that means the triangle starting out from O is isosceles since two of the sides are radii and thus the angle of those sides are the same
Let us call one of the angles z
we know that the sum of the angles in a triangle is 180 degrees
That simply means;
80 + 2z = 180
2z = 180-80
2z = 100
z = 100/2
z = 50 degrees
So the angles at each upper end of the cyclic quadrilateral are;
x + 50 and y + 50
we know that the angles that face each other in a cyclic quadrilateral are supplementary
Thus;
95 + y+ 50 = 180
y= 180-95-50
y= 180-145
y = 35 degrees
Now, for x, the angle supplementary to the angle that faces x+ 50 equals x + 50
Thus;
x + 50 = 105
x= 105-50
x = 55 degrees

The area of the base of a cylinder is 42 square inches and its height is 11 inches. A cone has the same area
for its base and the same height. What is the volume of the cone?
Answers
Volume of a cylinder: =∗2∗ℎ
V=π∗r2∗h
Volume of a cone: =∗2∗ℎ3
V=π∗r2∗h3
Where is the volume, ≈3.1416, r is the radius, and h is the height.
Cylinders and cones both have circle-bases, which means that the base area is the area of a circle: ∗2 , which means we will let =∗2
where B is the base area.
Which means that:
Volume of a cylinder: =∗ℎ
Volume of a cone: =∗ℎ3/3
If the cylinder and cone have the same base area and the same height, then the volume of the cone is always 1/3rd of the volume of the cylinder.
cone=cyl / 3
Given that the cylinder and cone have the same base area and the same height: If the volume of the cylinder is 43 cm3
, then the volume of the cone is exactly 1/3rd of 43 cm3, as shown below:
cyl=43 cm3
cone=43 cm3
=43/ 3 cm3
=14* 1/ 3 cm3
Thus the volume of the cone is 14* 1/3 cm3

In a square PQRS, PQ = 2x +3 cm and QR = 3x – 5 cm, then the value of x is
Answers
Answer:
x = 8 cm
Step-by-step explanation:
Given that,
In a square PQRS, PQ = 2x +3 cm and QR = 3x – 5 cm.
We need to find the value of x.
In a square, all the sides are equal. So,
PQ = QR
2x +3 = 3x – 5
3+5 = 3x - 2x
x = 8
So, the value of x is equal to 8 cm.
A boat travel 45 miles in three hours at this rate how many miles with a boat travel in half an hour
Answers
Answer:
7 1/2 miles per half hour
Step-by-step explanation:
First let's find how many miles you travel per hour. To find that, you divide 45 by 3. This gives you 15 miles per hour. Now we need to find how many miles in half an hour. To do this we are going to convert into minutes. We need to find out how many miles per minute. There are 60 minutes in 1 hour, so we will divide 15 by 60. That gives 0.25, or 1/4 mile per minute. So now that we know how many miles per minute, we can find out how many for half an hour. Half an hour is 30 minutes, so we are going to multiply 1/4 by 30. You will get 15/2. We need to make that a mixed number, and that gives us 7 1/2 miles per 30 minutes, or 7 1/2 miles per half hour.
I hope this helped :)
(edit: I just realized I did this the hard way. Sorry. The easier way would be to just divide 15 by 2 since it would take two halves of 15 to make the amount of miles per hour.)
