Solve For X. Helppp!
Answer:
x = 64
Step-by-step explanation:
The 3 angles on the right lie on a straight line and sum to 180° , that is
90 + x + 26 = 180
x + 116 = 180 ( subtract 116 from both sides )
x = 64
Answer:
64
Step-by-step explanation:
You have to do 90 - 26, which will then give you the answer 64
Double check it: 26 + 64 = 90.

Step-by-step explanation:
Which term can be used in the blank of 36x3−22x2−__ so the greatest common factor of the resulting polynomial is 2x? Select two options.
2
4xy
12x
24
44y
Given:
The expression is:
[tex]36x^3-22x^2-\_\_\_[/tex]
To find:
The values for the blank so that the greatest common factor of the resulting polynomial is [tex]2x[/tex].
Solution:
We have,
[tex]36x^3-22x^2-\_\_\_[/tex]
If the greatest common factor of the resulting polynomial is [tex]2x[/tex], then 2 and x must be factors of missing value.
In option A, 2 is a factor of 2 but [tex]x[/tex] is not a factor of 2. So, this option is incorrect.
In option B, 2 and [tex]x[/tex] are factors of [tex]4xy[/tex]. So, this option is correct.
In option C, 2 and [tex]x[/tex] are factors of [tex]12x[/tex]. So, this option is correct.
In option D, 2 is a factor of 24 but [tex]x[/tex] is not a factor of 24. So, this option is incorrect.
In option E, 2 is a factor of [tex]44y[/tex] but [tex]x[/tex] is not a factor of [tex]44y[/tex]. So, this option is incorrect.
It means the correct value for the given blank is either [tex]4xy[/tex] or [tex]12x[/tex].
Therefore, the correct options are B and C.

Answer: x= -52
Step-by-step explanation:
A game is played with the following rules. Three ordinary coins are flipped and count as a single "turn" in the game.
Each coin could land on heads or tails. After their turn a player is given a certain number of points depending on the
outcome.
•If the result is 3 heads, the player receives +4 points.
• If the result is 2 heads, the player receives +2 points.
• If the result is anything else, the player receives -1 point.
What is the expected value of the number of points a player will receive after a turn?
=======================================================
Explanation:
H = heads
T = tails
Something like HHT means we get two heads in a row at first, followed by one tail. The order matters. Since there are 2 sides per coin, and 3 coins, this leads to 2^3 = 8 different possible ways to flip three coins.
Those 8 outcomes are:
HHHHHTHTHHTTTHHTHTTTHTTTAgain the order matters.
------------
Now let's define the following events
A = event of getting three headsB = event of getting exactly two headsC = event of getting 1 head, or getting 0 headsThere's only one way to get three heads, and that's HHH. So P(A) = 1/8.
There are three ways to get exactly two heads. Those three ways are: HHT, HTH, THH. This means P(B) = 3/8.
From those two probabilities, we then know that P(C) = 4/8 = 1/2 since there are 1+3 = 4 ways to get two or more heads, leaving 8-4 = 4 ways to get the other situations.
Now let's define function notation V(A) to mean "the net value of event A occurring". It's the number of points you receive if event A happens. We are given the following info:
V(A) = 4V(B) = 2V(C) = -1From here, multiply the probability values with their corresponding net values
P(A)*V(A) = (1/8)*(4) = 0.5P(B)*V(B) = (3/8)*(2) = 0.75P(C)*V(C) = (1/2)*(-1) = -0.5Finally, add up those results to get the expected value: 0.5+0.75+(-0.5) = 0.75
Each time a turn happens, we expect on average to get 0.75 points
Imagine a scenario where you play the game 10,000 times. If you record the result of each turn and then compute the arithmetic mean, you should get somewhere close to 0.75; it likely wont be 0.75 exactly due to the nature of theoretical probability and empirical probability not being perfectly aligned. However, due to the law of large numbers, the two should be very close when you do a large number of trials.
Because we're dealing with averages, it is possible to get a decimal value as the answer even though the point values of events A,B,C are integers.
Hello, I need help! The question is "Today you will look over the following problem that Nancy worked and explain what she did incorrectly and why it does not work. Then tell me what information Nancy would need to know in order to use this theorem correctly"
Answer:
Step-by-step explanation:
Remark
The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?
It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).
The ratios are still true, but the angles do not match. So the whole answer is incorrect.

A motorboat averages 20 miles per hour (mph) in still water. It takes the boat the same amount of time to travel 3 miles with the current as it does to travel 2 miles against the current. What is the current's rate in mph?
Answer:
4 mph
Step-by-step explanation:
Let :
Boat speed = 20 mph
speed of current = x mph
Distance against current = 2 miles
Distance with current = 3 miles
speed against current will be ; 20 - x
speed with current will be ; 20 + x
Time =distance / speed against time against = time with current
Solving Mathematically ;
2/(20-x )=3/(20 +x)
2(20+x )= 3( 20-x )
40+2x = 60-3x
3x +2x=20
5x=20
x = 20 / 5
x = 4 mph
Speed of current = 4 mph
If each serving of the stew will contain 1 4 14 pound of meat, how many servings of the stew can the club make? Enter your answer in the box.
Complete question :
The line plot shows the weights of packages of meat that members of a club bought. The meat will be mixed with vegetables to make stew for a club dinner. Each serving of the stew contains 1/4 pound of meat. How many servings of the stew can the club make?
Answer:
36 servings
Step-by-step explanation:
From the plot ; we take the sum of total weight of meat packages :
(5/8 * 2) + 6/8 + 1 + (9/8 * 3) + 10/8 + 11/8
10/8 + 6/8 + 8/8 + 27/8 + 10/8 + 11/8 = 72 / 8 = 9 meat packages
Each serving of meat = 1/4
Number of servings the club can make :
Total meat package / pound of meat per serving
(9 ÷ 1/4)
9 * 4/1
= 36 servings
Answer:
36 hope this help

A bag has 6 red rocks, 1 orange rock, 4 blue rocks, 1 white rock, and 7 yellow rocks. You randomly pull a rock from the bag, keep it out and then pull out another one. What is the probability of not getting a orange and then not getting a orange?
Answer: 17/19
Step-by-step explanation:
Number of red rocks = 6
Number of orange rock = 1
Number of blue rocks = 4
Number of white rock = 1
Number of yellow rocks = 7
Total number of rocks = 19
Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.
Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18
Probability of not getting an orange on both occasion will be:
= 18/19 × 17/18
= 17/19

The circle shown on the radius of 10 units
Answer:
Dropdown 1: is 20
Dropdown 2: is 10
Step-by-step explanation:
The diameter is twice the length of the radius, so multiply 2 by 10 to get 20 as the diameter. Line CO has the same length as the radius, so it is 10.

The discriminant of the function f(x) = 2x2 – 3x + 3 is -15.
What is true about the function?
Answer:
The function has two unequal, complex roots
Step-by-step explanation:
Because the discriminant is negative, the function has two unequal, complex roots.
A submarine started 30 feet below the surface of the water. It is now 10 feet below the surface. What integer represents the change in depth?
Answer:
-20 feet
Step-by-step explanation:
change in depth = number of feet below the surface + number of depth on the surface
Because the submarine is below surface, a value of -30 would be given
-30 + 10 = -20 feet
given a is equal to 60 degree and 30 degree prove that sin a + b is equal to sin a cos b + cos a sin b
Answer:
A = 60 and B = 30
Now, A + B = 60 + 30 = 90
Also, A – B = 60 – 30 = 30
sin (A + B) = sin 90 = 1
sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30
