Answer:
The third answer
Step-by-step explanation:
(side note: You probably need to use a calculator that can calculate pi)
The formula to find the area of a circle is pi r squared.
In this case, pi times r squared is 19.63495....... continued
This is probably going to be rounded
so... 19.63
For all of the circles, this is multiplied by 4.
This is 78.52
The area of the square is 100 cm since 10 times 10 is 100
You take 100 cm and then subtract it by 78.54
Voila! now you have 21.46
Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
<h3>a)</h3>
we want to expand the following expression:

well to do so we consider distributive property thus distribute:

reduce fraction which yields:

simplify Parentheses:

<h3>b)</h3>
in the expression there's a common factor of 4 therefore factor it out:

Answer:
the numbers of apples consumed is : 110 - 80 = 30.
percentage of apple consumed is : (30 / 100) * 100=27.27%
remaining numbers of apple =100 - 27.27 = 72.72%...
this one is kinda Hard ill do sum research and help
You need to divide the miles by the hours to et the Average speed.
M divided by h = s
Because to get the mph (miles per hour) you multiply the average speed to the hours.
S•h=mph
