Answer:
Therefore he should sell 25 units of tacos to minimize his cost .
The minimum cost is $240.
Step-by-step explanation:
Given function,
where C is the cost in dollar to sell x units of tacos.
We know that,
If a function y(x)= ax²+bx+c,
then the function is minimum at 
Here a= 1 , b= -50 and c= 865.
Therefore
Therefore he should sell 25 units of tacos to minimize his cost .
putting the value of x in the given function
C(25)=25²-(50×25)+865
=240
The minimum cost is $240.
Answer:
90 m^2
Step-by-step explanation:
Area = l*w
45 = l*15
Divide each side by 15
45/15 = l*15/15
3 =l
We want 2 *(l*w)
2 * (3*15)
2 *(45)
90
Answer:
Given the information, the value of x is 20.
Step-by-step explanation:
For this problem, we have to find the ratio between the line segments in order to find the value of x.
We are already given two line segments that we can find the ratio for. We are given 30 and 12. In order to find the ratio, then we must divide 12 by 30.
12 ÷ 30 = 0.4
Now that we have our ratio, we can now divide 8 by 0.4 to find the value of x.
8 ÷ 0.4 = 20
So, the value of x is 20 which is the third answer choice in the problem.
Answer:
Ricardo spends $14 on the backpack and $11 o the binder.
Step-by-step explanation:
First, you have to calculate 56% of the amount Ricardo has to spend on school supplies to find the money he spends on the backpack:
$25*56%=$14
Now, you have to subtract 56% from 100% to find the percentage that he spent on a large binder:
100%-56%=44%
Finally, you have to calculate the 44% of the amount Ricardo has to spend on school supplies to find the money he spends on a large binder:
$25*44%=11
According to this, the answer is that Ricardo spends $14 on the backpack and $11 o the binder.
