The zero product property tells us that if we have
xy=0, then we can assume that x and y both equal 0
so
(4k+5)(k+7)=0
we can assume that 4k+5=0 and k+7=0
so
4k+5=0
minus 5 both sides
4k=-5
divide both sides by 4
k=-5/4
k+7=0
minus 7 both sides
k=-7
k=-5/4 or -7
Answer:
120
Step-by-step explanation:
to find the volume you just do length x width x height.
He makes commission of 15% on everything he sells.....so if he sells 293 worth of stuff, then he would make 15% of 293
15% of 293.....turn ur percent to a decimal..." of " means multiply
0.15 * 293 = 43.95 <==
Answer:
The possible numbers of songs that you can burn onto the CD is 11.
Step-by-step explanation:
The total storage capacity of CD = 70 minutes
Storage already used = 25 minutes
Hence, The available storage = Total available storage - Used Storage
= 70 minutes - 25 minutes = 45 minutes
Hence, the CD has 45 minutes storage left.
Now, each song takes up 4 minutes of storage.
⇒ ![\textrm{Total number of songs possible} = \frac{\textrm{Total storage left}}{\textrm{Time taken by each song}}](https://tex.z-dn.net/?f=%5Ctextrm%7BTotal%20number%20of%20songs%20possible%7D%20%3D%20%20%5Cfrac%7B%5Ctextrm%7BTotal%20storage%20left%7D%7D%7B%5Ctextrm%7BTime%20taken%20by%20each%20song%7D%7D)
= ![\frac{45 minutes}{4minutes } = 11.25](https://tex.z-dn.net/?f=%5Cfrac%7B45%20minutes%7D%7B4minutes%20%7D%20%20%3D%2011.25)
⇒The number of songs possible = 11.25 ≈ 11
Hence, the possible numbers of songs that you can burn onto the CD is 11.
Answer: Use all numbers to add.
2918+49=2967
Estimated.... 2918+49 ≈ 3050
Hope this helps you out.
