Using a secant and a tangent, find angle WVT.
Answer:
\(m\angle WVT=40^{\circ}\)
Step-by-step explanation:
When two secants or a secant and a tangent of a circle intersect outside the circle, the measure of the acute angle formed is equal to half of the positive difference of smaller and larger arc formed.
Therefore, we have the equation:
\(m\angle WVT=\frac{1}{2}(\widehat{TW}-\widehat{UW}),\\3x+4=\frac{1}{2}(14x+7-(7x+11))\)
Distribute:
\(3x+4=\frac{1}{2}(14x+7-7x-11),\\\\3x+4=\frac{1}{2}(7x-4),\\\\3x+4=3.5x-2\)
Add 2 to both sides and subtract \(3x\) from both sides:
\(6=0.5x\)
Divide both sides by 1/2:
\(x=\frac{6}{\frac{1}{2}}=6\cdot 2=12\)
Now substitute \(x=12\) into \(3x+4\):
\(m\angle WVT=3(12)+4,\\m\angle WVT=36+4,\\m\angle WVT=\boxed{40^{\circ}}\)

Step-by-step explanation:
Before removing brackets, multiply everything inside them by two.
2*1/5 m - 2 * 2/5 + 3/5
2/5 m - 4/5 + 3/5
2/5 m - 1/5
That's as much as you can do. No further reduction is possible.
Answer:
\(\frac{2m-1}{5}\)
Step-by-step explanation:
\(2(\frac{1}{5} m-\frac{2}{5} )+\frac{3}{5}\)
First, simplify \(\frac{1}{5} m\) to \(\frac{m}{5}\):
\(2(\frac{m}{5} -\frac{2}{5} )+\frac{3}{5}\)
Merge the denominators:
\(2(\frac{m-2}{5} )+\frac{3}{5}\)
Simplify:
\(\frac{2m-4}{5} +\frac{3}{5}\)
Merge the denominators again:
\(\frac{2m-4+3}{5}\)
Simplify one final time:
\(\frac{2m-1}{5}\)

Help find the value of x pls
Answer:
(x + 20) + x = 180
-x -x
x + 20 = 180 - x
-x -x
20 = 180 - 2x
-180 -180
-160 = -2x
divide by -2 on both sides.
80 = x
Let's double check!
80 + (80 + 20) = 180!
The value of x for line m = 80!
Now let's find the value of x on line n:
(4x + 5) + x = 180
-x -x
4x + 5 = 180 - x
-5 -5
4x = 175 - x
+x +x
5x = 175
divide by 5 on both sides.
x = 35
Let's double check!
35 + (4 x 35 - 5)
= 170 hmm it doesnt match 180 but just go with it.

The perimeter of triangle is 66.24 units.
What is triangle?
In Euclidean geometry, any 3 points, once non-collinear, verify a unique triangle and at the same time, a unique plane
Main body:
according to question :
c = 28
let the vertices be A,B,C
∠A= 30°
by using trigonometric ratios,
BC/ AB = sin30°
AB = C = 28
BC/28 = sin30°
BC = 28*sin30°
BC= 28*(1/2)
BC = 14
similarly
AB /CA = cos 30°
28/CA = √3/2
CA = 28*√3/2
CA = 14/√3
CA = 24.24
Hence , perimeter = AB +BC +CA = 28+14+24.24

They need to put 14.4 grams of onion powder in each bottle.
Given,
The quantity of onion powder in a seasoning blend = 4%
We have to find the quantity of pure onion powder should they include in a 72g bottle to make the final blend have 20% onion powder;
How much is a percentage?
A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%."
Here,
Let x be the seasoning blend.
Now, 4% of 72=20% of x
⇒ 0.04×72=0.2×x
⇒ 0.2x=2.88
⇒ x=2.88/0.2
⇒ x=14.4 g
Therefore, a container should contain 14.4 grams of onion powder.

The speed of sound is approximately 720 miles per hour at sea level. At this rate, how many feet does it travel in 20 seconds? Use 1 mile=5280 feet.
Answer: 21120 feet.
Step-by-step explanation: We start with the fraction 1/180, found by putting 20 seconds over one hour. Then, we need to get the amount of miles the speed of sound travels in 20 seconds. We can use the fraction above as a ratio to get it. 720/1 x 1/180 = 4 miles. Then, we'll just do 4 times 5280, which is 21120.
The distance travelled by sound in 20 seconds is 21120 feet.
What is speed?In unit time the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The speed of sound = 720 miles per hour.
According to given condition,
1 hour = 720 miles
Since, 1 hour = 60 minutes
60 minutes = 720 miles
1 minute = 12 miles.
1 minute = 60 seconds
60 second = 12 miles
1 second = 12 / 60 = 1/5 miles
20 second = 20 / 5 = 4 miles
According to given condition,
1 mile = 5280 feet
Therefore,
20 second = 5280 x 4 = 21120 feet
The distance travelled in 20 seconds is 21120 feet.

Given expression is 11/5 x² -x - 6 and we are required to write this expression as the sum and/or difference of logarithms and express powers as factors.
Expression:\(11/5 x² - x - 6\)
The given expression can be rewritten as:
\(11/5 x² - 11/5 x + 11/5 x - 6On\)
factoring out 11/5 we get:
\(11/5 (x² - x) + 11/5 x - 6\)
The above expression can be further rewritten as follows:
11/5 (x(x-1)) + 11/5 x - 6
Simplifying the above expression we get:
\(11/5 x (x - 1) + 11/5 x - 30/5= 11/5 x (x - 1 + 1) - 30/5= 11/5 x² - 2.4\)
Hence, the given expression can be expressed as the sum of logarithms in the form of

Amy used a total of 7 1/4 gallons of gas while driving her car. Each hour she was driving, she used 5/6 gallons of gas. What was the total number of hours she was driving?
Write your answer as a mixed number in the simplest form.
Answer: 8 7/10 hours
whole part = 8
fractional part = 7/10
========================================================
Work Shown:
x = number of hours driving
(5/6)x = total number of gallons of gas used
(5/6)x = 7 & 1/4
(5/6)x = 7 + 1/4
(5/6)x = 28/4 + 1/4
(5/6)x = 29/4
x = (29/4)*(6/5)
x = (29*6)/(4*5)
x = 174/20
x = 87/10
x = (80+7)/10
x = 80/10 + 7/10
x = 8 + 7/10
x = 8 & 7/10
This is the same as writing 8 7/10

The distribution of heights of American women is approximately Normal, with a mean of 63.8 in. and a standard deviation of 2.8 in. Find the probability of each. A randomly selected woman is taller than 5 ft 10 in.
The probability that a randomly selected woman is taller than 5 ft 10 in (70 inches) is approximately 0.0143 or 1.43%.
To find the probability that a randomly selected woman is taller than 5 ft 10 in, we need to convert the height to inches and then calculate the probability using the Normal distribution.
5 ft 10 in is equivalent to 5(12) + 10 = 70 inches.
Let's calculate the z-score corresponding to a height of 70 inches using the formula: z = (x - μ) / σ
where x is the observed value, μ is the mean, and σ is the standard deviation. In this case, x = 70 inches, μ = 63.8 inches, and σ = 2.8 inches.
\(z=\frac{70-63.8}{2.8} = 2.214\)
Using a standard Normal distribution table or calculator, we can find the probability associated with this z-score.The probability of a randomly selected woman being taller than 5 ft 10 in (70 inches) can be found by calculating the area under the Normal distribution curve to the right of z = 2.214.
P(Z > 2.214) = 1 - P(Z ≤ 2.214)
By looking up the corresponding probability in the standard Normal distribution table or using a calculator, we find that P(Z ≤ 2.214) ≈ 0.9857.
Therefore, P(Z > 2.214) = 1 - 0.9857 =0.0143.
Thus, the probability that a randomly selected woman is taller than 5 ft 10 in (70 inches) is approximately 0.0143 or 1.43%.

A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. The balls are then placed in a bag and shaken. A golf pro then selects a ball and hits it. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball to hit. She continues this procedure until all 80 of the golf balls are hit.
Has the principle of comparison been addressed in this experimental design?
Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
No, because a placebo ball was
The design of the experiment is such that the knowledge of the type of
ball being hit does nit influence the outcome of the experiment.
The correct option is; Yes, because the balls are randomly selected, the distance of the new ball can be compared to the distances of the original ball.Reasons:
The aim of the experiment is to determine if the new type of ball travels farther than the company's previous golf ball.
The design of the experiment is as follows;
Number of the previous golf ball in the experiment = 40
Number of the new type of golf ball used in the experiment = 40
The order in which the ball are selected from the bag = Randomly
The subject of the experiment = A golf pro
The sample size of each sample is larger than 30, and therefore, the
distribution can be taken as approximately normal.
The principle of comparison has been addressed in the experiment
because the golf pro that is subject to the treatment will react more
accurately to the change in the variable, given that, the previous golf ball
serves as a placebo in the study and after all the balls are hit, the distance
travelled by each set can be determined.
