The mean of four numbers is 30 are 12,50 and 48 what is the fourth number.a)129 b) 10 c) 12 d)30
Answers
You know that there are 4 numbers and you have to add the numbers then divide them by four to get the mean. So all you have to do is reverse the steps, multiply 30 by 4 to get 120, then add 12+50+48 to get 110. Then subtract, 120-110=10. To check if it is correct add 12, 50, 48, and 10 to get 120, then divide by 4 to get 30. And voila, there is the answer. I hope this helped for future problems like this one.

Michael writes the expression shown here as 12(a + b + c + d). He is correctly using the ___________ property.
A) associative
B) commutative
C) distributive
D) symmetric
Answers
C) the distributive property of addition/multiplication
The expression shown here is using the distributive property.
What is distributive property?The distributive property simply states that multiplication distributed over addition. Multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
For the given situation,
The expression is 12a + 12b + 12c + 12d.
The formula for the distributive property is expressed as,
a × (b + c) = (a × b) + (a × c).
Michael writes the expression shown as
⇒ [tex]12a + 12b + 12c + 12d = 12(a + b + c + d)[/tex]
The above expression is of the form of the formula for the distributive property.
Hence we can conclude that the expression shown here is using the distributive property.

Evaluate the expression 40÷1+3-(3×7)+7-5
Answers
First of all, you will want to solve for the values inside the parentheses first
40 ÷ 1+3-(21)+7-5 Now check for anything that includes multiplication/division and do that
40+3-21+7-5 All you have left now is addition and subtraction. It must go from left to right, therefore if addition is first, do addition, if subtraction is first, then do subtraction.
Final answer = 24
40/1=3-(3 times 7) + 7-5
First the parenthesis.
(3 times 7 is 21 )
40/1+3-(21)+7-5
Next is exponents but there are none so move on to division.
40/1 = 40
40+3- (21) + 7-5
Then add and subtraction from left to right.
40+3=43
43- 21 + 7-5
43-21 is 22.
22+7-5
7-5 is 2
22+2 is 24
24 is the answer! :)

Which expression is equivalent to 4(3x+5y+2z)+3(x-z)
A. 12x+20y+8z
B. 5(3x+4y-z)
C. 15x+20y+5z
Answers
Final answer:
The expression 4(3x+5y+2z)+3(x-z) is equivalent to 15x+20y+5z.
Explanation:
To simplify the expression 4(3x+5y+2z)+3(x-z), you need to distribute the 4 and 3 to each term inside the parentheses.
When you distribute the 4 and 3, you get 12x+20y+8z+3x-3z. Combine like terms to simplify further, which gives us 15x+20y+5z.
Therefore, the expression 4(3x+5y+2z)+3(x-z) is equivalent to C. 15x+20y+5z.

You are solving for p :)
So, in order to find the value of p, you must get p to it's own side, and isolate it.
Since there are two "p's," you could change "xp + yp" to "p(x + y).
p(x + y) = z
Then, we must divide both sides by x + y
p(x + y) ÷ x + y = z ÷ x + y
Simplify.
p = z/x + y

Answer:
B) 23,.8 feet
Step-by-step explanation:
It forms a right triangle.
We use the trigonometric ratio of cos to find the answer.
cos = adjacent /Hypotenuse
Here hypotenuse is the length of the ladder and adjacent side represent the ladder toughs the wall from the ground.
cos 18 = adjacent / 25
adjacent = 25*cos18

A line passes through the points (6,5) and (2,2) . Select all that describe this line.
1. y − 5 = 3/4 (x − 6)
2. y − 5 = −4/3 (x − 2)
3. y − 2 = −3/4 (x − 6)
4. y − 2 = 3/4 (x − 2)
Answers
The equations that describe the line passing through the points (6,5) and (2,2) are: [tex]1. y-5=\frac{3}{4}(x-6)$\\2. $y-2=\frac{3}{4}(x-2)$[/tex]
To determine which of these equations describe the line passing through the points (6,5) and (2,2), we can use the point-slope form of a linear equation:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line, and [tex]\left(x_1, y_1\right)[/tex] is one of the given points.
Let's find the slope using the two points:
[tex]\begin{aligned}& m=\frac{y_2-y_1}{x_2-x_1} \\& m=\frac{2-5}{2-6}=\frac{-3}{-4}=\frac{3}{4}\end{aligned}[/tex]
So, the slope of the line passing through these points is m=3/4
Now, let's plug in one of the given points into the point-slope form to check which equations match:
[tex]y-5=\frac{3}{4}(x-6)\\\text{If we plug in the point (6,5)} :\\& 5-5=\frac{3}{4}(6-6) \\& 0=0\end{aligned}$$[/tex]
This equation holds true for the point (6,5).
[tex]y-5=-\frac{4}{3}(x-2)\\\\text{If we plug in the point (2,2)} :\\2-5=-\frac{4}{3}(2-2) \\& -3=0\end{aligned}$$[/tex]
This equation does not hold true for the point (2,2).
[tex]y-2=-\frac{3}{4}(x-6)\\\text{If we plug in the point (6,5)} :\\& 5-2=-\frac{3}{4}(6-6) \\& 3=0\end{aligned}$$[/tex]
This equation does not hold true for the point (6,5).
[tex]y-2=\frac{3}{4}(x-2)\\\text{If we plug in the point (2,2)} :\\& 2-2=\frac{3}{4}(2-2) \\& 0=0\end{aligned}$$[/tex]
This equation holds true for the point (2,2).
So, the equations that describe the line passing through the points (6,5) and (2,2) are:
[tex]1. y-5=\frac{3}{4}(x-6)$\\2. $y-2=\frac{3}{4}(x-2)$[/tex]
what is the angle of n
Answers
-----------------------------------------------------------------------------------
-----------------------------------------------------------------------------------
Explanation:
The top and bottom lines are parallel as indicated by the same arrow markings on the lines.
Because they are parallel, this makes the angle x (see attached image) congruent to the 44 degree angle. They are alternate interior angles. So x = 44.
Using x = 44, we can find the angle y. Use the fact that all three angles of a triangle add to 180 degrees. We'll focus on the top triangle.
x+y+37 = 180
44+y+37 = 180 ... replace x with 44
y+44+37 = 180
y+81 = 180
y+81-81 = 180-81
y = 99
The last step we do is use this y value to find the value of n. Notice how the angle n and angle y combine to form a straight angle (aka straight line). So they add to 180 degrees
n+y = 180
n+99 = 180 ... replace y with 99
n+99-99 = 180-99
n = 81
which is the final answer
-----------------------------------------
Side Note: you can ignore the value of y if you want. Using the remote interior angle theorem, we add up the remote interior angles for the top triangle to get
x+37 = 44+37 = 81
which is the answer we got earlier.
