Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
First off we need to find the denomonator:
11+37+83+19=150
Okay so our probability of getting a small size of a t-shirt will be 11/150
They sold 45,000
That's where we need to change our denominator to get how many shirts were small
45,000÷150=300
300×11=3,300
I multiplied 11 because of the numerator
So our answer is B. 3300
Answer: DB = 9 I think.

Answer:
66 degrees! Hope it Helps!!!!
Step-by-step explanation:
So the total angle amount of a square is 360
lets first figure out what x is...
angle B and angle D is equal, forming a equation.
6x-96=3x
simplify that...
x=32
Now pluggin x into the equation (6x-96)&(3x)
96 and 96
Now add all the angles forming this equation: (?+102+96+96=360)
?=66
Answer:
We have that y = 21 when x = 11.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.
33 - 7
y - 11
So
11y = 33 -7
y - 11
Dividing both sides by 11
Y = 3 * 7 = 21
We have that y = 21 when x = 11.
