Answer:
If the price is p and the cost is c, then
15p = 20c
p/c = 20/15 = 1.333
so, he made 33% profit
Answer:
Plan A and plan B both lasts for 1.25 hours.
Step-by-step explanation:
Trainer has two solo workout plans Plan A and Plan B.
Let the trainer trains for plan A = x hours and for plan B = y hours
As per statement given in the question,
"Dueshan trained his Monday clients for a total of 10 hours"
Equation will be, 3x + 5y = 10 --------(1)
And other statement says,
"Dueshan trained his Tuesday clients for a total of 10 hours"
6x + 2y = 10
3x + y = 5
y = 5 - 3x ----------(2)
Replace the value of y in equation 2 from equation 1.
3x + 5(5 - 3x) = 10
3x + 25 - 15x = 10
25 - 12x = 10
12x = 25 - 10
12x = 15
x =
x = 1.25 hours
From equation 1
y = 5 - 3×1.25
y = 5 - 3.75
y = 1.25 hours
Therefore, plan A and plan B both lasts for 1.25 hours.
Answer: solve for x
x ∈ R, h = 0 and g = 0
Step-by-step explanation:
So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original <em>plus</em> the new percent) Simply set it up like so:
SN *120% = $324.00
Now turn the percent into a decimal:
SN * 1.20 = $324.00
Now divide $324.00 by 1.20
SN = $270
The original value of the basketball player's autograph was 270 dollars!
Hope that helps!
Answer:
c. 12x; 111 cm
Step-by-step explanation:
The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

and if we substitute x = 9.25 cm, we find
