Please mark Brainliest
Step-by-step explanation:
[tex]\frac{14+29}{2}[/tex]
Is the mean
Before I calculate, I will explain WHY the fraction above appeared
What is the mean and how to find it?
This is how:
We add all the numbers in the dataset and then divide by the amount of numbers in the given dataset.
Something you might think:
What are you talking about?!
The fraction above shows everything.
There are 2 numbers in the dataset, so we divide by 2.
14+29=43/2=21.5

Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
Answer:
-6
Step-by-step explanation:
Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly
f(x) = 12 / 4x +2
Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side
f(-1) = 12/ 4(-1) + 2
f(-1) = 12 / - 4+2
= 12/ - 2
= - 6

(x+2)+10=44 please help
Answer:
[tex]x=32[/tex]
Step-by-step explanation:
Given the equation:
[tex](x+2)+10=44[/tex]
Begin by subtracting 10 from both sides of the equation:
[tex]x+2=34[/tex]
Then, subtract 2 from both sides of the equation to find the value of [tex]x[/tex]:
[tex]x=32[/tex]
-
You can check your answer by substituting the x-value into the initial equation:
[tex](32+2)+10=44[/tex]
[tex]34+10=44[/tex]
[tex]44=44[/tex]
Since both sides of the equation are equal, our solution is correct.
Answer:
[tex] = > (x + 2) + 10 = 44[/tex]
Subtracting 10 from both sides:
[tex] = > (x + 2) + 10 - 10 = 44 - 10[/tex]
[tex] = > x + 2 = 34[/tex]
Subtracting 2 from both sides:
[tex] = > x + 2 - 2 = 34 - 2[/tex]
[tex] = > x = 32[/tex]
Thus,the value of x is 32.
For checking:
[tex] = > (x + 2) + 10 = 44[/tex]
Putting x=32
[tex] = >( 32 + 2) + 1 0= 44[/tex]
[tex] = > 32 + 2 + 10 = 44[/tex]
[tex] = > 34 + 10 = 44[/tex]
[tex] = > 44 = 44[/tex]

Answer:
65° and 115°
Step-by-step explanation:
Supplementary angles add up to 180
So if you add A and B you get 180°
x + 50 + x + 100 = 180
2x + 150 = 180
2x = 30
x = 15
A = 15 + 50
A = 65
B = 15 + 100
B = 115

A boy's age in ten year time will be four times his age five years ago. Find his present age.
Answer:
He is ten.
Step-by-step explanation:
10 yrs old. Go ahead 10 yrs to make 20. Which is four times as much as five years old. (Which is 5 years before 10)
Hope this helps! :)
Answer:
Present age = 10
Step-by-step explanation:
Let us assume that,
→ Present age = x
Forming the equation,
→ x + 10 = 4(x - 5)
Now the value of x will be,
→ x + 10 = 4(x - 5)
→ x + 10 = 4x - 20
→ x - 4x = -20 - 10
→ -3x = -30
→ x = -30/-3
→ x = 30/3
→ [ x = 10 ]
Hence, the boy's age is 10.

The formula for the volume V of a cylinder is V =TTr2h , where r is the radius of the base
and h is the height of the cylinder. Solve the formula for h. Then find the height of a
cylinder with a volume of 54TT cm3 and a base with a radius of 3 cm.
type your answer
Answer:
I think the first part is just
h = v/TTr2
the second part is about 1.9099
Step-by-step explanation:
the first part is just moving the TTr2 part under the v
the second part is to find the base area. which is TTr2, then divide the height by the base area

what equation represents the line that passes through the points (7,15) and (-4,4)?
Equation of line is y = mx +b
Passing through (-3,7 )
X= -3, y= 7
plug in these
7 = -3m + b ... .Eq1
Also X = 4 , y= 10
10 = 4m + b ............... Eq 2
Solve Eq 1 and Eq 2 for m and b
m= 3/7
b= 58/7
Thus y =( 3/7) X + 58/7 is equation of line

The front of a house is in the shape of a hexagon with two right angles.
The other four angles are all the same size.
Calculate the size of one of these angles.
Answer: 135°
Step-by-step explanation:
The sum of the interiors angles of the hexagone is (6-2)*180°=720°
Two angles are right: 2*90°=180°
The sum of the four angles is 720°-180°=540°
Each angle is 540°/4= 135°
Why does the common ratio in an infinite geometric series have to be between 1 and -1? Why doesn't -2 or 2 work? Please help with this. Thanks in advance!
Answer:
A n+1 / A n the ratio of successive terms will be less than 1 if A is between -1 and 1 so successive terms will have a ratio less than 1 and can be determined
If A n+1 / A n > 1 then successive values of the given ratio will not approach a constant value
If you write the value of the nth term as L = a r^(n - 1) one can see that r^(n - 1) approaches a fixed value if r between -1 and 1 but not if | r | > 1

Find ""k"" so that the 58 unit diagonal of a rectangle can have an aspect ratio of 15:8. Then find the length and width of the rectangle and find its area.
Step-by-step explanation:
The area of any 2-d quadrilateral is equal to the base of the shape times the height, though we can just sub in length and width here. The key bits of information here is the aspect ratio (4:3) and the given area (300 in^2).
So far this gives us L∗W=300in2
Now, the aspect ratio given implies for every 4 inches in length, there will be 3 inches in width. This allows us to factor out a 4 and a 3 from the Length and Width respectively and give them the same constant variable, like so:
4x∗3x=300in2
Now, some might be tempted to go ahead with 12x here, but let’s expand the left side out to see what’s really going on:
4∗x∗3∗x=300in2
From here, let’s resolve like terms Our constants will multiply together and give us 12, and x * x of course gives us x^2 to give us the following:
12x2=300in2
From here, simply divide through by 12 to isolate x on one side,x2=25
And finally take the square root of both sides to work out what your common factor is,
x=5
Now that we have out common factor, let’s plug it back into our original formula to find our Length and Width, like so.
(4∗5)in∗(3∗5)in=300in2
20in∗15in=300in2
Therefore, the Length of our rectangle is 20in, and the Width of our rectangle is 15in

Answer:
x=17 degrees
m1=97 degrees
Step-by-step explanation:
6x-19=3x+32(vertically opposite angles)
6x-19-3x=32
3x =32+19
3x=51
x=17 degrees
when we substitute x in these:
6x-19=83
3x+32=83
if 1=y
83+83+Y+Y=360(points around a point is 360 degrees)
166+2Y =360
2Y =360-166
2Y=194
Y=97
Therefore 1=97 degrees
