Find the value of x ?

Mathematics
1 answer:
RUDIKE [14]3 years ago
6 0

Answer:

x = 50

Step-by-step explanation:

add all terms and set sum equal to 360

the 'hint' of (n-2)180 determines how many degrees there are inside the polygon; if 'n' equals the number of sides and the polygon has 4 sides then sum of interior angles is (4-2)180 or 2x180 which is 360

x + 10 + 3x + x + 2x = 360

combine like terms to get:  7x + 10 = 360

                                             7x = 350

                                              x = 50

Given the two rectangles below. Find the area of the shaded region. 4 4 9 3​
LuckyWell [14K]

Answer:

60

Step-by-step explanation:

The shaded region's area is the difference between the area of the outer rectangle and the white rectangle.

area = LW - lw

area = (4 + 4)(9 + 3) - (4)(9)

area = (8)(12) - 36

area = 96 - 36

area = 60

Describe how to transform the graph of f into the graph of g. f(x) = square root of quantity x minus nine. and g(x) = square roo
ruslelena [56]

Answer:

Translate the graph 14 units horizontally to the left by adding to the x-variable the constant 14.

Step-by-step explanation:

Translations of "c" units in the horizontal axis are obtained by adding or subtracting the constant value "c" to the variable x itself. When we want to translate the graph to the right, we subtract c, and when we want to move the graph horizontally to the left , we add c.

In this case, to go from the radicand (x-9) to the radicand (x+5), an addition of 14 units has to be performed, and such corresponds to a horizontal displacement to the left in 14 units.

If µ = 400 and s = 100 the probability of selecting at random a score less than or equal to 370 equals ____.
Alja [10]
You'll need to calculate the applicable z-score:
        (given value of x) - (mean value)
z = -----------------------------------------------
                standard deviation

                  370-400            -30
Here, z = ---------------  =  ---------- = -0.3
                      100                100

Use either a table of z scores or your calculator to determine the area under the standard normal curve to the left of z = -0.3.

According to my TI-83 Plus calculator, this area is 0.382.

The probability of selecting at random a score less than or equal to 370 is 0.382.
