Answer:
(B) The equation of line is 5 X = 2 Y.
Step-by-step explanation:
2 ounces of pineapple juice
5 ounces of fruit punch
Other is 4 ounces pineapple juice and 10 ounces fruit punch
(A) Graph is shown below:
(B) Let X is the pineapple juice and Y is the fruit punch
(2, 5) and (4, 10)
So, the equation of line is

Answer:
The system has exactly one solution where x = 0 and y = -3.
Step-by-step explanation:
-6x + y = -3
7x - y = 3
(7x - 6x) + (y - y) = 3 - 3
x + 0 = 0
x = 0
7(0) - y = 3
0 - y = 3
-y = 3
y = -3
-6(0) + y = -3
0 + y = -3
y = -3
So, the system has exactly one solution where x = 0 and y = -3.

62.5 mg sample will remain after 240 days
Step-by-step explanation:
Given
Half-life = T = 60 days
The formula for calculating the quantity after n half lives is given by:

Here
N is the final amount
N_0 is the initial amount
n is the number of half lives passed
The number of half lives are calculated by dividing the time for which the remaining quantity has to be found by half life
The quantity has to be calculated for 240 days so,

Given

Putting the values in the formula

Hence,
62.5 mg sample will remain after 240 days

Answer:
1626.24
Step-by-step explanation:
You need to take the sample(2541) and divide it by the percentage so you would do 2541 x .64 =1626.24
The miles per hour is 84 kilometers per 60 minutes (7:5 ratio) so if we take seven kilometers times the ratio 5/7 we get 5 minutes
