What is the value of w?
Answer:
x=29.3 degrees
Step-by-step explanation:
Vertical angles are congruent therefore the angle with the dot in it is 60.7 degrees and the combination of the dot and w is 90 degrees. 90-60.7=29.3
The triangular base of the given prism has an interior angle with a measure of 80° and an interior angle with a measure of 55°. What is the measure of the unknown angle?
A. 45°
B. 65°
C. 75°
D. 85°
Answer:
A. 45°
Step-by-step explanation:
When we are given two measurements of interior angles we add both of those angles together.
Also know that a triangle equals 180 degrees
So when we write out this expression [tex]80+55+x=180[/tex]
[tex]135+x=180\\-135=-135\\x=45[/tex]

What is the probability of choosing a gray button not replacing it and choosing gray again?
answer:
the probability of choosing a gray button is 3/5
after putting it back the probability remains the same, so 3/5 for both answers
Answer:
[tex]\sf \dfrac{3}{10}[/tex] = 0.3 - 30%
Step-by-step explanation:
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Given:
Grey buttons = 3White buttons = 2Total buttons = 5[tex]\sf P(gray) = \dfrac35[/tex]
If the button is not replaced, there are now:
Grey buttons = 3 - 1 = 2White buttons = 2Total buttons = 5 - 1 = 4[tex]\sf P(gray) = \dfrac24=\dfrac12[/tex]

To approximate the length of a marsh, a surveyor walks x=420 meters from point A to point B,then turns 75 degrees and walks 220 meters to point C (see figure). Approximate the length AC of the marsh. (Round your answer to one decimal place. )
Applying the law of cosine, b² = a² + c² - 2ac(cos B), the length of AC of the marsh, to one decimal place, is: 522.1 meters
What is the Law of Cosine?The Law of Cosine is given as, b² = a² + c² - 2ac(cos B).
From the diagram given, we have the following:
B = 180 - 75 = 105°b = AC (length of the marsh)a = 220 mc = 420 mPlug in the values into the law of cosine formula:
b² = 220² + 420² - 2(220)(420)(cos 105)
b² = 272,629.8
b = √272,629.8
b = 522.1 meters. (Length of AC of the marsh)

The first part of the second step to prove the sequence is to prove that Sn is valid for n = k + 1, Option D is correct.
What is geometric sequence?Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
The sum of geometric sequence is given as,
[tex]s_n=\dfrac{r^n-1}{r-1}[/tex]
Here, a is the first term of the sequence, n is total terms and r is the common ratio.
The given equation which need to be proved is,
[tex]S_n= 1 + 2 + 4 +. ...+ 2n - 1 = 2n - 1[/tex]
This can be proved by induction method. This can be done by induction method with two steps:
Prove n=0, without getting any data of other cases.If the data or problem is given then assume n=k. For the given case is also true for n=k+1. Thus, in second step prove that Sn is vaild for n=k+1.Thus, the first part of the second step to prove the sequence is to prove that Sn is valid for n = k + 1, Option D is correct.

A group photograph of a family of six (4children and their parents)is to be taken.if the parents must occupy the two middle seats.then the number of different arrangements is
Answer:
Let's find the number of arrangements with mother and father together, say N & then subtract it from total number of arrangements.
Total arrangements = 6! = 720.
Now, as mother & father are together, let's treat mother and father as a single person. Now, there're 5 persons.
Number of arrangements in this way = 5! = 120.
But mother and father can change their places in 2! = 2 ways.
N = 120 × 2 = 240.
Ans. = 720-240 = 480.

What is the percent of the silo that is filled with corn at 10 hours. Use the picture bellow to get the answer.
Answer:
90.93%
Step-by-step explanation:
It is clear that the table is a linear function. That is, every hour, the amount of corn increases by the same amount. You can find the slope of the linear function by using the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
In your case, the number comes out to be 825. So the number of corn will be 825*10 = 8250 cu ft.
Now, we know that the volume is area times height. So if the area is pi * r * r, then the volume of the shape is 2888*pi.
Therefore, the answer is 8250/2888*pi or 90.93%.
A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An item priced at $150 has a fee of $9.
What percentage of the item is a restocking fee?
Divide the restocking fee by the price of the item:
12/200 = 0.06
9/150 = 0.06
Multiply by 100 to get the percent:
0.06 x 100 = 6%
Answer: 6%
