Answer:
what you do is first you find out what 4 to the second power is do then you find what 6 to the second power is then you add the two answers you just got. after that you find the square root of the number you just got and that is the answer.
A.)90
B.)41
C.)15
D.)83
Answer:
D
Step-by-step explanation:
∠ABC= ∠DBE (vert. opp. ∠s)
(6x -7)°= (4x +23)°
6x -7= 4x +23
Being x terms to 1 side, constant to the other:
6x -4x= 23 +7
Simplify:
2x= 30
Divide both sides by 2:
x= 15
Substituting the value of x:
m∠ABC
= 6(15) -7
= 83
What is the value of X
Answer:
x = 30
Step-by-step explanation:
The two angles add to a right angle which is 90 degrees
30 +2x = 90
Subtract 30 from each side
30 +2x - 30 =90-30
2x= 60
Divide each side by 2
2x/2 = 60/2
x = 30

Write the other side of this equation so it's true for no values of x: }(6x - 10) - x =
Answer:
(6x - 10) - x = 5(x - 2)
Step-by-step explanation:
6x - 10 - x
5x - 10
5x - 10 = 5(x - 2)
5x - 10 = 5x - 10
5x - 10 ÷ 5 = 5x - 10 ÷ 5
x - 2 = x - 2
No solution.
x - 2 + 2 = x - 2 + 2
x = x

What is the sum of the measures of the interior angles of this heptagon?
A) 720°
B) 900°
C) 1,080°
D) 1,260°
The sum of the measures of the interior angles of the given heptagon is 900°, Option B is correct
What is Polygon?a polygon is a plane figure made up of line segments connected to form a closed polygonal chain.
The sum of the measures of the interior angles of a heptagon can be found using the formula:
S = (n - 2) × 180°
where S is the sum of the measures of the interior angles and n is the number of sides (or vertices) of the polygon.
For a heptagon, n = 7, so we have:
S = (7 - 2) × 180°
S = 5 × 180°
S = 900°
Therefore, the sum of the measures of the interior angles of the given heptagon is 900°, which is answer choice B.

Find the mean absolute deviation in the following data set: 23, 42, 36, 63, 31
Answer:
39.2 is the mean
the deviation is 15.2
Step-by-step explanation:
the mean of a set of numbers is the sum divided by the number of terms = 39.2
the deviation measures the spread of a data distribution of the sample = 15.2
Answer:
10.8
Step-by-step explanation:
To find the mean absolute deviation, first you need to find the mean. To find the mean, add up 23 + 42 + 36 + 63 + 31 and you'll get 195. Divide 195 by the total of numbers, which is 5, and you'll get 39.
After finding the mean, you need to find the distance between the mean, which is 39, and the numbers given. 23 is 16, 42 is 3, 63 is 24, 31 is 8, and 36 is 3. Then, you'll need to calculate the mean of the distances that you got.
16 plus 3 plus 24 plus 8 plus 3 = 54. Once you got this, divide 54 by the total of numbers, which is 5, and you'll get 10.8.

Find the measure of WX
Answer:
WX = 66°
Step-by-step explanation:
The inscribed angle WXY is half the measure of its intercepted arc, then
arc WY = 2 × 57° = 114°
XY is a diameter of the circle, so
arc XY = 180°
Thus
arc WX = 360° - (180 + 114)° = 360° - 294° = 66°

Answer:
148cm²
Step-by-step explanation:
With the first frontal face of the cuboid, you have length 6 cm whilst the height remains 5 cm.
Find the area of this face and multiply the result by 2, as there are two of these faces (front and back)
6 x 5 = 30 cm²
30 x 2 = 60cm²
Do the same with the top face and bottom face, adding this with the side faces
4 x 6 = 24cm²
24 x 2 = 48cm²
4 x 5 = 20cm² x 2 = 40 cm²
40 + 48 + 60 = 148 cm²
T.S.A = 148cm²

f(n) = _______________
Use n as your variable.
Use the ^ symbol to represent an exponent.
For example: 52 should be typed as 5^2
Answer:
f(n) = 2 * 4^n
Step-by-step explanation:
The initial population = a male and a female = 2
The population quadruple every year, this means, a multiplication by 4 every year.
Hence, we have :
f(n) = (Initial population * multiple^years)
f(n) = 2 * 4^n
. Determine f(4.5) for the function f(x) = 3x - 5 *

f(4.5)=8.5
Plug in x as 4.5 and multiply it with 3. Then subtract 5 from the remaining result.
Answer:
f(4.5) = 8.5
Step-by-step explanation:
f(4.5) = 3x - 5
f(4.5) = 3(4.5) - 5
f(4.5) = 13.5 - 5
f(4.5) = 8.5
Hope that helped! You have to substitute x with 4.5 and then solve.
