Answer:
Step-by-step explanation:
4 cups of tea per minute.......lunch lasts 2 hrs.....there are 120 minutes in 2 hrs...so in 2 hrs, there will be (4 * 120) = 480 cups
and if there is 16 cups in 1 gallon, the caterer needs to bring :
480 / 16 = 30 gallons <==
I think i need a bit more information but assuming if this is what you are looking for:
to write 50,000 in exponent form look for its multiples other than 1 and itself and then go from there.
This is what i general do, i pick a divisible number and keep dividing till i get to one.
50,000/2 = 25,000
25,000/5 = 5,000
5,000/10 = 500
500/10 = 50
50/10 = 5
5/5 = 1
so i divided by 2, 5,10, 10, 10, and 5 (three 10s, two 5s and one 2)
then i look if these numbers can be written in smaller divisible numbers (i.e. 10 is 2 and 5)
so 2, 5, (2,5), (2,5) ,(2,5), and 5 as you can see that cannot be divided into smaller numbers so we have thus five 5s and four 2s
therefore 50,000 = 5^5 x 2^4
hope this helps :P
(P.S. it is the best way i can explain online without a whole course on this)
B) 0.56
becouse you only need to divide 5 by 9
Divide it by -1 to get positive 81
Answer:
The equivalent factored form of this equation is (x² + 49)(x - 6)
Step-by-step explanation:
<em>x³ - 6x² + 49x - 294</em>
First, group the first and second terms together and group the last two terms together.
<em>(x³ - 6x²) + (49x - 294)</em>
Find the greatest common factor of both parentheses and factor them.
x²(x - 6) + 49(x - 6)
Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.
So, the factored form of the equation is (x² + 49)(x - 6)
