Answer:
(b) The planet's mass =10.241032 kilograms.
Step-by-step explanation:
Here, the mass of Neptune = 1024 1032 milligrams
Also, given: 1 milligram = 0.0000001 kilograms.
or, 1 milligram =
kilograms.
Now, to convert 1024 1032 milligrams in to kilograms, we get:
1024 1032 milligrams =
kilograms.
Now solving
, we get:
kilograms.
Hence the planet's mass =10.241032 kilograms.
<h3>20 subtracted from three times a number is 6 more than the number. Then the number is 13</h3>
<em><u>Solution:</u></em>
<em><u>Given statement is:</u></em>
20 subtracted from three times a number is 6 more than the number
We can translate the sentence into algebraic expression
Let "a" be the unknown number
Then,
20 subtracted from three times "a" is 6 more than "a"
Which means,
3a - 20 = 6 + a
3a - a = 6 + 20
2a = 26
Divide both sides by 2
a = 13
Thus the number is 13
Answer:
The scale factor is 1 to 1.3
Step-by-step explanation:
Here, we want to get the scale factor
To get the scale factor, we divide corresponding sides by each other
That, we have that
9/7 = 1.3
Circumference = 2 × π × r
circumference = 2 × 3.14 × 5.4
circumference = 33.912
circumference = 33.9 in²
Answer:
The correct option is B
B) (1/729)c²⁷
Step-by-step explanation:
Lets write it all in an understandable form.
The given expression is:
( 9c ⁻⁹ ) ⁻³
The given options are:
A) 9c²⁷
B) (1/729)c²⁷
C) 729c²⁷
D) 9/c²⁷
Lets find the solution. The given expression is:
( 9c ⁻⁹ ) ⁻³
Multiply the outer power -3 with each term inside the bracket. It can be rewritten as.
(9⁻³) ( c ⁽⁻⁹⁾⁽⁻³⁾)
A negative power can be converted into positive by taking it down in the denominator.
The multiplication (-9)(-3) results in 27.
The equation can be written as:
( 1/9³) ( c²⁷)
Where 9³ = 729
( 1/729)( c²⁷)
which is equal to option B
