Answer:
10x+5 so D
Step-by-step explanation: hope this helps;)
Answer:
x^2-2x-4=0
Δ=2^2-4*1*(-4)
Δ=4+16=20
VΔ=2V5
x1= (2+2V5)/2=1+V5
the answer is D
Step-by-step explanation:
You find the midpoint by using the formula m=(x1+x2 then divide by 2, and y1+y2 divided by 2) that’s how you find midpoint and the (5,13) 5-x1 13-y1 and so on hope this helps!
Answer:
I belive your answer is v = 162 \pi cm³
Step-by-step explanation:
\pi 9²(6/3)
\pi 81(2)
\pi 162
volume of a cone = \pi r²(h/3)
When talking about surveys (and most other things) we use 100% as the cap. You can not work harder than 100% efficiency and you can not have more than 100% of people agree with you. You can think of this as a pie.
A whole pie would be 100%
A half a pie 50%
Etc.
You can not have more than a whole pie (without adding another pie or variable in this case)
So when you look at this problem with that analogy in mind, all it is is simple addition and subtraction.
If you create a survey and 82% of people vote yes, how many, out of 100%, voted yes.
To find this we take 100% (The whole pie or everybody who voted) and - the portion of the pie we ate or everyone who voted yes, 82%, which will give us the answer, everyone who voted no or the pie that is left on the platter.
So your equation would be 100 - 82 =18
18% of people interview used internet someplace other than in the home. <span />
