Solution
A=4πr2=4·π·82≈804.24772
Approximately = 804.25
Answer:
Since there are 4 green bars for every 3 red bars and we are trying to find the number of red bars if there are 200 green bars, we can create the ratio:
4
x
:
3
y
Where x is equal to the number of green bars and y
is the number of red bars.
We know the number of green bars is equal to 200, so we can divide it by 4, giving us:
200
/4=50
Then we can solve for y
, the number of red bars.
// Multiple y by 50
3
⋅
50
=
150
So for every 4 green bars, there are 3 red bars.
For every 200 green bars, there are 150 red bars

Answer:
x = 77 degrees
Step-by-step explanation:
angle x = (76 + 78)/2 = 154/2 = 77 degrees
Use the Chord angle theorems
Answer:
A B C
Step-by-step explanation:
Let A,B and C be the number of seats in section A,B and respectively. The situation can be represented by the following system. 1. A+B+C=49,000 2. 25A+20B+50C=1,052,000 and 3. A=B+C
Answer:
○ C. The lines are perpendicular.
Step-by-step explanation:
In order for equations to be perpendicular, their <em>rate of changes</em> [<em>slopes</em>] must be OPPOSITE <em>MULTIPLICATIVE</em><em> </em><em>INVERSES</em>, which in this case is so:
− to +}
> OPPOSITE
+ to −}
MULTIPLICATIVE INVERSE [RECIPROCAL]
