Answer:
Step-by-step explanation:
8.
slope=(83-3)/(10-0)=80/10=8
y-3=8(x-0)
y=8x+3
when x=20
y=8(20)+3=163
243=8x+3
243-3=8x
8x=240
x=240/8=30
when x=40
y=8*40+3=320+3=323
9.
(0,8) and (5,6)
m=(6-8)/(5-0)=-2/5=-0.4
y-8=-0.4(x-0)
y=-0.4x+8
Answer:
so then it to be 25000
Step-by-step explanation:
The quantity demanded would increase due to the cheaper price people would want to take advantage and buy it when it was on sale. There is not enough information to determine whether the supply or demand would maintain so D is your answer.
Answer:
25% and is an increase
Step-by-step explanation:
Games won last month=eight games
Games won this month=ten games
Change in the number of games won=This month- Last month=10-8= 2 games
Percentage change in games won=100*change/original games
Numerical percentage change=100*2/8=25%
This is a positive change hence an increase.
Therefore, percentage change in game the team won is 25% and is an increase
Answer:
Look at my explanation
Step-by-step explanation:
The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.
2πr = 22π
divide both sides by 2
πr = 11π
divide both sides by π
you get r = 11
So your radius is 11.
To find the area, you must do πr^2 ("^2" means squared)
if you substitute 11 for r you get
11π^2
you can do 11 squared first
11^2 = 121
the area of the circle = 121π
Keep in mind that they said to use 3.14 for π
so you can do 121 x 3.14
Final Answer: 379.94
