AE is about half of AC. What I did was get half of 28, which is 14, and represented one of the numbers.
3 x 7 = 21 - 7 = 14
It is D.
(I don't know for sure if this is right, but I did the best I could)
30: r = -32
38: n < -24
54: ?
4 and 5
4^2= 16
5^2= 25
Square root of 21= 4.5
Answer:
The answer is t=1/9
Step-by-step explanation:
If we substitute sqrt(t) = u, then we can write the equation as 3u^2+5u-2=0.
Using the <em>quadratic formula</em>, we can solve that <u>u = 1/3 and u = -2.</u>
We can go back to our original substitution and say that <em>sqrt(t) = 1/3</em>. The sqrt(t) can not be -2 because a <u>square root can not be negative.</u>
If we solve the equation sqrt(t) = 1/3, we get that t=1/9.
Answer:
The greatest number of arrangements that he can make if every balloon is used is 8.
Step-by-step explanation:
The greatest number of arrangements will be the greatest common factor between 24 and 32.
GCF of 24 and 32:
We keep factoring both numbers by prime factors, while they can both be divided by the same number. So
24 - 32|2
12 - 16|2
6 - 8|2
3 - 4
There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.
This means that the greatest number of arrangements that he can make if every balloon is used is 8.
