Answer:
It's 63.29
Step-by-step explanation:
Step 1: We make the assumption that 158 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=158.
Step 4: In the same vein, x%=100.
Step 5: This gives us a pair of simple equations:
100%=158(1).
x%=100(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 158/100
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 100/158
x= 63.29%
Therefore, 100 is 63.29% of 158.
Answer:
$149.60
Step-by-step explanation:
12% = .12
.12 × 170= 20.40
$170- 20.4= $149.60
Answer:
The vertex represent the minimum amount of profit
Step-by-step explanation:
Plot the function to better understand the problem
Let
x ----> the number of users in thousands
y ---> the Monthly profit in thousands
using a graphing tool
see the attached figure
we have a vertical parabola open upward
The vertex represent a minimum
In the context of this problem
The vertex represent the minimum amount of profit
In this problem the vertex is the point (0.4,-4)
0.4 represent -----> 0.4(1,000)=400 users
-4=-4(1,000)=-$4,000 (profit negative)
Answer:
no solution
Step-by-step explanation:
If first equation is divided by 2 and the second equation is divided by 3, we get two equations 2x+y=3 and 2x+y= 4. These two lines are parallel and there cannot be any solution to the system
The value of this equation is: 4
Answer: 4
