Answer:
<u>Given:</u>
To find the area of the rug, we need to use the formula "πr² or π(D/2)²"
<u>Where:</u>
Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.

⇒
Substituting "22/7" as π:
⇒
⇒
When finding the area of ANY shape, do not forget to include the units.
⇒
There's only information to answer question C.
We can only know that 32 marbles were chosen. (yellow and black)
Why?
To answer the first two questions (a and b), we need to know the total number of marbles, so, we can only answer the last question (c).
We know that 7/10 of the 20 yellow marbles were chosen.
So, calculating we have:
Also, we know that 18 black marbles were chosen, so, the total of marbles chosen is equal to 32 (yellow marbles and black marbles)
Have a nice day!
Answer: The table and figure are given below,
Solution:
The given equation is .
put x=0 in the equation.
Similarly find the values of y at different values of x. The values are shown in the table.
From table it is notices that the value of y=-2 for x=0, y=-1 for x=3, y==-3 for x=-3, y=0 for x=6.
Plot these points in the coordinate plane and joint them by a straight line.
The gra his shown in below figure.
