Answer:
a. On the 13th day
b. 2,451 players we’re sold on that day
Step-by-step explanation:
a. The day in which the company sold the same number of players can be calculated by equating the values of y that we have ;
y = 191x-32 and y = -x^2 + 200x + 20
Equating both, we have;
191x-32 = -x^2 + 200x + 20
x^2 -200x + 191x-20-32 = 0
x^2-9x-52 = 0
x^2-13x + 4x -52 = 0
x(x-13)+4(x-13) = 0
(x-13)(x+4) = 0
x = 13 or -4
as days cannot be negative we choose only x = 13
This means the company sold equal numbers of players on the 13th day
b. To get the number of players sold on that day, we choose any of the y equation and substitute x = 13
Thus, we have for y = 191x -32; 191(13) - 32 = 2,451 players
I think it’s 216) because you do 6 times 6 then times that by 6
Answer:
the answer is -48. _______
Ratio and proportion
real:shadow
so the person is 1.8m but the shadow is 4m
so
real:shadow=1.8:4
so
1.8:4=?:14
1.8/4=?/14
times both sides by 14
25.2/4=?
6.3=?
the tree is 6.3 m tall
Angela uses this recipe, but she using twelve times the amount of everything. Therefore, we will do (150g*12=1,800). To turn this to kg, we will divide by 1,000 to get 1.8 kg.
hope this helped!
