Answer:
6
Step-by-step explanation:
57=15+7x --> 57-15=7x --> 42=7x --> 42/7=x --> 6
Answer:
It is rational
Step-by-step explanation:
The pi terms cancel out when you divide. This is due to the rule x/x = 1 where x is any number you want except x cannot be zero. So replace x with pi and we have pi/pi = 1
Therefore,
(3pi)/(2pi) = (3/2)*(pi/pi)
(3pi)/(2pi) = (3/2)*1 .... use the rule mentioned above
(3pi)/(2pi) = 3/2
we get a fraction or a ratio of two whole numbers, so this proves that the given expression is rational.
To find the angle of vertex E,we need to first find the sum of interior polygons to determine x:

In this case,the equation would be:
(7-2)×180°
=5×180°
=900°
We can then find the value of x:
(4)6x+(2)2x+8x=900°
24x+4x+8x=900°
36x=900°
x=25°
The interior angle of vertex E:
6x=6(25)=150°
Therefore,the interior angle of vertex E is 150°.
Hope it helps!
Answer:
Shaquille O'Neal's height= 2,160,000,000 nm
= 2.16 × 10^9 nm
Completed question;
The basketball player Shaquille O'Neal is 7 feet 1 inch tall, which is equivalent to 216 centimeters a nanometer (nm) is a unit of measurement that is one-billionth of a meter, convert his height to nanometers.
Step-by-step explanation:
Given;
Shaquille O'Neal's height= 216cm = 216 × 1/100 m = 2.16m
Since, a nanometer (nm) is a unit of measurement that is one-billionth of a meter.
1 m = 1 billion nanometers
So,
2.16m = 2.16 billion nm = 2160000000 nm
Shaquille O'Neal's height= 2160000000 nm
= 2.16 × 10^9 nm
