There are 9 toy trucks in each group.
27 divided by 3 is 9. Therefore when you divide the trucks up in EQUAL groups the answer has to be 9.
1 yd 2 ft
* 8
----------------
8 yd 16 ft
but we can reduce 16 ft
there are 3 ft in a yd
16/3 = 5 yds with 1 left over
8 yds 16 ft = 8 yds + 5yds 1 ft
13 yds 1 ft
Answer:
The cost of printing 142 more posters when 18 has already been printed is $5.57.
Step-by-step explanation:
We are given that the marginal cost (dollars) of printing a poster when x posters have been printed is given by the following equation C'(x)=x^-3/4.
The given equation is:
The cost of printing 142 more posters when 18 have already been printed is given by;
Integrating both sides of the equation and using the limits we get;
As we know that
, so;
=
= ![\frac{x^{\frac{1}{4} } }{\frac{1}{4} } ]^{142} __1_8](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%20%7D%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%20%5D%5E%7B142%7D%20__1_8)
=
= ![4[(142)^{\frac{1}{4} }- (18)^{\frac{1}{4} }} ]](https://tex.z-dn.net/?f=4%5B%28142%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D-%20%20%2818%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%7D%20%5D)
= $5.57
Hence, the cost of printing 142 more posters when 18 has already been printed is $5.57.
210/600 = 35% B
1/4 of 600 = 150 C
Is it the step by step equation?
