If the entire student population seems a lot higher than 10 people, I say no. It just depends on the student population. Please look at the earlier parts and respond with a comment what the entire student population is, but if there is no specifications, I would assume they should find a larger sample because 10 people is not accurate to find a general opinion over a larger population.
Answer:
x=2
Step-by-step explanation:
7x+9=9x+5 [Corresponding angles]
9-5=9x-7x
4/2=x
x=2
Step-by-step explanation:
I think this might be correct you can see for yourself if you think this is good
solution: 5 packs
let a be plates and b be packs
100a = 5b
= (20*5)a
sorry if confusing I'll say it here
packs is 20 plates and you need 100 plates
just divide the plates you need (100) and the plates per pack (20) and that's how many packs you need to get(5)
Answer:
Step-by-step explanation:
Begin by grouping the x terms and the y terms together and separating the constants out.
Now we'll complete the square on those x and y terms. Take half the linear term of each, square it, and add it to both sides. Our linear x term is 2, half of 2 is 1 and 1 squared is 1, so we add that in. Likewise, half the linear y term (which is 8) is 4, and 4 squared is 16, so we add that in, too. Like this:
Doing this gives us the perfect square binomials for each of the x and y terms, and then gives us the radius on the right:
This is a circle with a center of (1, 4) and a radius of 3.
Answer:
the answer is A. 6 1/3 feet
Step-by-step explanation:
There are 12 inches in a foot. 12 x6=72 r of 4
there are 12 inches in a foot 12÷4=3. 1/3 of a foot
6 + 1/3= 6 1/3
