Find the length of strapping (in inches) needed to attach a pipe to the wall. Assume the wall is at a right angle and the straps connect to the wall at right angles.
Answers
The length of strapping (in inches) needed to attach a pipe to the wall. Assume the wall is at a right angle and the straps connect to the wall at right angles is 31.77 in.
Length of strappingGiven :
Length = 16.00 in diameter pipe
Now let determine or find the Length since the diameter pipe is 16.00 in.
Length :
Length = 1.10 ×2 + 16.00 /2 × 2 + 1 /4 π · 16.00
Length = 3.20 + 16.00 + 4π
Length = 19.20 + 4π
Length = 31.766
Length = 31.77 inches (Approximately)
Therefore the length is 31.77 inches.

Use the Law of Sines to find the indicated angle 0. (Assume C = 67º. Round your answer to one decimal place.)
Answers
Answer
40.3º
Explanation
The Sine rule is used to solve angles and sides of triangle.
If a triangle ABC has angles A, B and C at the points of the named vertices of the tringles with the sides facing each of these angles tagged a, b and c respectively, the sine rule is given as
[tex]\frac{\text{ Sin A}}{a}=\frac{\text{ Sin B}}{b}=\frac{\text{ Sin C}}{c}[/tex]For this triangle,
Angle A = ? (Isn't given)
Angle B = θ
Angle C = 67º
Side a = ? (Isn't given)
Side b = 56.3
Side c = 80.2
We are then told to find the Angle B, that is, θ
So, using the later parts of the Sine Rule
[tex]\frac{\text{ Sin B}}{b}=\frac{\text{ Sin C}}{c}[/tex]Substituting the known variables, we have
[tex]\begin{gathered} \frac{\text{ Sin B}}{b}=\frac{\text{ Sin C}}{c} \\ \frac{\text{ Sin }\theta}{56.3}=\frac{\text{ Sin }67º}{80.2} \\ \text{ Sin }\theta=\frac{56.3\times\text{ Sin }67º}{80.2}=\frac{56.3\times0.9205}{80.2} \\ \text{ Sin }\theta\text{ = 0.6462} \\ \theta=Sin^{-1}(0.6462)=40.3º \end{gathered}[/tex]Hope this Helps!!!
Interpret the decay factor from the exponential function y = 900(0.65)3.
Answers
Answer:
0.65
Explanation:
If we have an exponential equation of the form
[tex]y=ab^x[/tex]where
a = inital amount
b = decay factor
Now in our case, the function we have is

the inital amount = 900
the decay factor = 0.65
Hence, the decay factor of the exponential function is 0.65.
A map of Levi's property is being made with a scale factor of 2 centimeters: 3 meters. Whats the scale factor
Answers
As a result, if 2 centimeters on the map equals 3 meters, you might express that as a fraction and convert it to a standard unit of meters: 0.02 / 3, which you could then multiply by 50 / 50 to get the fraction 1 / 150. The scale factor 1 is 150.
What is Scale Factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2. The new figure we receive will resemble the first figure, but every dimension will be double that of the first rectangle. The scale factor in this case will be denoted by the number 2.Scale factor = Dimension of the new shape Dimension of the original shape is the fundamental formula used to calculate it. The formula is expressed as Scale factor = Larger figure dimensions Smaller figure dimensions in the event that the original figure is enlarged.

Determine whether the given numbers represent the lengths of sides of a right triangle.9,40,41Do the given numbers represent the lengths of the sides of a right triangle?YesNo
Answers
To prove that these numbers form the sides of a right triangle we should do these steps
1. Square the longest side
2. Find the sum of the squares of the other 2 sides
3. If the sum equals the square of the longest side, then the numbers can form a right triangle
Since the longest side is 41, then
[tex](41)^2=1681[/tex]Since the other 2 numbers are 40 and 9, then
[tex](40)^2+(9)^2=1600+81=1681[/tex]From both steps, we can say

- This is a binomial probability problem because we have multiple trials.
- The formula for calculating the Z-value is:
[tex]\begin{gathered} Z=\frac{X-\mu}{\sigma} \\ where, \\ \mu=\text{ The mean} \\ \sigma=\text{ The standard deviation} \\ X=\text{ The value we are testing} \end{gathered}[/tex]- This value of Z can be used to calculate the probability we need using a Z-score calculator or a Z-distribution table.
- Before we proceed, we need to find the mean and the standard deviation as follows:
[tex]\begin{gathered} \mu=np \\ n=\text{ Number of subjects} \\ p=\text{ The probability of success} \\ \\ \mu=\frac{6}{100}\times538 \\ \\ \mu=32.28 \\ \\ \sigma=\sqrt{np(1-p)} \\ \sigma=\sqrt{538\times\frac{6}{100}(1-\frac{6}{100})} \\ \\ \therefore\sigma=5.5085 \end{gathered}[/tex]- Now that we have both the mean and the standard deviation, we can proceed to find the value of the Z-score as follows:
[tex]\begin{gathered} Z=\frac{X-\mu}{\sigma} \\ \\ Z=\frac{28-32.28}{5.5085} \\ \\ \therefore Z=-0.78\text{ \lparen To 2 decimal places\rparen} \end{gathered}[/tex]- Now that we have the Z-score value, we can proceed to find the corresponding probability for values less than X = 28 sales using a Z-distribution table or a Z-score calculator.

Find the value of x.
Answers
Answer:
x = 82
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides = (n-2) x 180°
This polygon has 7 sides so the sum of its interior angles
= (7-2) x 180°
= 5 x 180°
= 900°
Adding up the given angles we get
x + 160 + 2x + 125 + 110 + 112 + 147 = 900
3x + 654 = 900
3x = 900 - 654
3x = 246
x = 246/3 = 82
Answer:
x = 82
Step-by-step explanation:
Sum of interior angles of a polygon
[tex]S=(n-2) \times 180^{\circ}[/tex]
where n is the number of sides.
The given polygon has 7 sides:
n = 7To find the value of x, substitute the sum of the interior angles and the found value of n into the formula and solve for x:
[tex]\implies x+160+2x+125+110+112+145=(7-2)\times 180[/tex]
[tex]\implies x+2x+160+125+110+112+145=5\times 180[/tex]
[tex]\implies 3x+654=900[/tex]
[tex]\implies 3x+654-654=900-654[/tex]
[tex]\implies 3x=246[/tex]
[tex]\implies \dfrac{3x}{3}=\dfrac{246}{3}[/tex]
[tex]\implies x=82[/tex]
Therefore, the value of x is 82.

PLEASE HELP IM SICK AND I DONT UNDERSTAND.DUE IN 30 MINS!!!!!!

Answer:
x = 11
Step-by-step explanation:
all angles in a triangle will add up to 180.
So we can start with the equation:
(19 + x) + (7 + 8x) + angle str = 180.
we are given the angle stv. This angle equals 125.
the angle of a straight line is 180. In order to find the angle next to another angle like angle stv and str are, all you have to do is subtract the angle from 180.
So to find str:
180 - 125 = 55
we already have one of our angles which is 55
so the equation is now:
(19 + x) + (7 + 8x) + 55 = 180
now do some simple simplification:
(19 + x) + (7 + 8x) + 55 = 180
______________ -55_-55
(19 + x) + (7 + 8x) = 125
26 + 9x = 125
-26_____-26
9x = 99
99/9 = 11
x = 11
Therefore, x = 11

A man who weighs 200 lbs goes on a diet and loses 16%of his body weight. How much weight, in ounces, did he loses?
Answers
We know that the man loses 16% of his weight, to find how much was that we just have to multiply his total weight by 0.16, like this:
lost weight = 0.16 * total weight, by replacing 200 lbs for total weight, we get:
lost weight = 0.16 * 200 = 32
Now we need to express 32 lbs in ounces, we can do this by multiplying the weight in pounds by 16, since 1 pound is equivalent to 16 ounces, then we get:
lost weight in ounces = 32 * 16 = 512
Then, the man lost 512 ounces
