n*8 + 8 = n*7 --> the answer must be n = -8 because:

8n + 8 = 7n

8n - 8n + 8 = 7n - 8n

8 = -1n

-8 = n

Find the value of X, please explain!

Monica [59]

All four angles are exterior angles of the quadrilateral.

We know that the sum of exterior angles of any polygon is 360 ° .

So we can add together the four angles and solve for x:
(x+16)+(3x-1)+6x+5x = 360
15x+15=360
15x=345
x=345/15=23 °

A marble tile measures 20 cm by 15 cm.how many tiles will be required to cover a wall of size 5m by 3m?

Rainbow [258]

First, we get the area of each tile: (100 cm = 1m)
.20 m* .15 m = 0.03m^2
Then, we solve for the total area of the wall:
5m*3m= 15m^2
Then we divide
15/0.03 = 500 tiles

Find the distance x rounded to<br> the nearest tenth.

anyanavicka [17]

Answer:

$x=0.1 ~ft$

Step-by-step explanation:

$cot30=\frac{B}{H} =\frac{B}{H}$

$\frac{\sqrt{3} }{2} =\frac{B}{H}=H=\frac{16}{\sqrt{3} }$

$sin70=\frac{X}{H} =\frac{P}{H}$

$sin70=\frac{x}{\frac{16}{\sqrt{3} } }$

$x=\frac{\sqrt{3} }{16 ~sin70}$

$=0.1152$

$x=0.1$

What is the gravity of a location if the mass of an object is 300 kg and it has a weight of 450N ?

kozerog [31]

The gravity is 1.5m\s^2

Further explanation:

The weight of any object is given by the product of mass and gravity of the object

Let

m denote the mass of object

g be the gravity

and

w be the weight

Then the statement can be mathematically written as:

$w=m*g$

Given

m=300kg

w=450N

Putting the values of m and w into the formula

$450=g*300\\g= \frac{450}{300}\\g=1.5\ ms^{-2}$

The gravity is 1.5m\s^2
