$1.35
because if they want to raise $108 and are going to sell 80 glasses then each drink should be $1.35X80=108
hope this helped:)
Answer:
y=-3x/2+2
Step-by-step explanation:
slope of original line : 2/3
slope of line perpendicular:
(m)(2/3)=-1
m=-3/2
point slope form:
(y+1)/(x-2)=-3/2
2y+2=-3x+6
y=-3x/2+2
Answer:
Explanation:
10) Given:
hypotenuse = 20
angle = 45°
To find:
length of s
angle = 45
opposite = side opposite the angle = s
To find the value of s, w will apply sine ratio (SOH)
Answer:
The answer is 7،3
Step-by-step explanation:
[tex]3 {(x - 5)}^{2} - 1_11 =0 \\ = 3( {x}^{2} - 10x + 25) - 12=0 \\ = 3 {x}^{2} - 30x + 75 - 12=0 \\ = 3 {x}^{2} - 30x + 63=0
(x-7)(x-3)=0
X=7
X=3
Answer:
It is false that, if the national economy shrank at an annual rate of 9% per year for three consecutive years then the economy shrank by 27% over the 3-year period, because this percentage does not follow a linear path, but on the contrary, it is calculated exponentially: 9% of each year is calculated on the rest that remained after discounting 9% the previous year.
Thus, if the national economy has a value of 100, after three years it will not have a value of 79, but a value of 75.35, as it arises from the following calculation:
100 x 0.91 ^ 3 = X
100 x 0.753571 = X
75.35 = X
