Answer:
10 pencils for $4.00 is better.
Step-by-step explanation:
If you divide 4.00 by 10 you'll find that each pencil is worth 40 cents. When you divide 2.70 by 6 then each pencil is worth 45 cents paying more for each pencil than the other deal.
Answer: A
Step by step explanation: I got it correct in edg. Good luck! Have a great day.
The first statement comes about because
a could be (say) 5
b could be (say) 6
Then c would be square root of 25 + 36 = 61 which is irrational.
I'm not sure of the wording of the second one. It reads like (5 + 6)^2 = 121 the two rationals added together make a rational number in my example. So I think that part is wrong. the second part is correct. For example sqrt(5) + sqrt(6) doesn't produce anything that is rational.
It doesn't have to. pi^2 + [cube root(10)]^2 does not produce anything rational and that is certainly not a perfect square. My first example shows that as well
I think the last one might be true.
P+ p(.08)= 51.84
p is the original price of the item
if you take 51.84 which is the total amount after taxes are added and divide it
by 1+tax you will get the original price
so if p + p(.08)=51.84 then 51.84/1.08= p
p =48
48+ 48(.08)=51.84
Answer:
One
Step-by-step explanation:
13/sin(55) = 12/sinC
sinC = 0.7561403486
C = 49.1, 130.9
Since 130.9+55 = 185.9 > 180
It will not form a triangle.
So only one triangle possible with angle 49.1° at C
