Answer:
Circumference of a circle= 
Step-by-step explanation:
The circumference of any circle is the total length of its boundary which can be calculated by the formula:
Circumference of a circle= 
Where 'r' is the radius of the circle
For, the given circle the circumference can be find in terms of
by putting some value of radius in the formula, which gives the circumference in terms of
.
Answer: 8(x+5) 8x + 40
40 + 8x
Step-by-step explanation:
Distribute the 8 by multiplying by each value inside the parentheses.
Commutative property in addition and multiplication allows the terms to be in reversed order.
Answer:
262
Step-by-step explanation:
3(90) - 8 = x
270-8 = x
262 = x
Answer:

Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are
number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is
=6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is
