Answer:
3yz^3 + 1
Step-by-step explanation:
t(5x^3yz^2) = 15x^3y^2z^5 + 5x^3yz^2
t = [5x^3yz^2(3yz^3 + 1)]/5x^3yz^2
t = 3yz^3 + 1
Have a good day your amazing!!!
Answer: b) 6
Step-by-step explanation:
Given : The illuminance of a surface varies inversely with the square of its distance from the light source.
i.e. for d distance and l luminance , we have
, where k is constant. (1)
If the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters.
From (1), we have
(2)
For the distance (d) corresponds to the illuminance to 30 lumens per square meter , we have
Put value of k , we get
Then , the number of meters should the distance of the surface from the source be increased= 12 meters- 6 meters = 6 meters.
(87.50 divided by 10) times # of Bballs purchased = C cost of any balls
(87.50/10)b=c
If 1 cup of chocolate chips weighs about 6 ounces
The recipe calls for 3 1/4 cups of chocolate chips.
We need to multiply 6 by 3 which is 18 ounces plus the 1/4 which is 6 times 1/4 = 1.5 ounces
18 + 1.5 = 19.5 ounces of chocolate chip needed
