Answer:

3960 minutes

Step-by-step explanation:

From;

0.693/t1/2 = 2.303/t log No/N

t1/2 = half life of 90Y

No = initial activity of 90Y =  8.9 x 10^5 disintegrations per minute

N= activity of 90Y after time t = 2.6 x 10^4 disintegrations per minute

t = time taken

Since the time elapsed is 20,235 minutes, we substitute into the formula above.

0.693/t1/2 = 2.303/20235 log 8.9 x 10^5/2.6 x 10^4

0.693/t1/2 =  1.75 * 10^-4

t1/2 = 0.693/ 1.75 * 10^-4

t1/2 = 3960 minutes

Answer:

Since the Width (W) of the rectangle is not given, the answer would be Length (L) = 240/W

Step-by-step explanation:

A = L*W

240 = L*W

240/W = L

Answer:

C=50+20h

Step-by-step explanation:

The $50 dollars in this equation is a flat fee, no variable to it. It doesn't increase or decrease depending on the number of hours. The $20 dollars is dependent on the number of hours the plumber works. If the plumber works 2 hours they get $40 dollars, the amount the plumber receives depends on the hours worked. The h in the equation is a placeholder for hours worked. To solve the equation just replace h with the hours worked and solve to get the answer.

Answer:

A. 169 is the correct answer

False; consider the functions f(x) = x and g(x) = x + 1. Clearly f(x) ≠ g(x), but both f '(x) = 1 and g'(x) = 1.

Answer:

trick:

1 hour = 60 minutes

ex if said to convert 25 minutes to hour so

1 hour/60=1minutes

multiply both sides with 25

25 x 1hour/60=25minutes

5/12 hours=25 minutes

just like that for hour

Base = 5 * 12 = 60 in^2

Height = 4 in

Perimeter is the sum of all straight

Perimeter = 20 + 16 + 48

Perimeter = 84 in

Perimeter of base = 12 * 2 + 5 * 2 = 34

Answer:

C.

Step-by-step explanation:

The slope intercept form is:

y= mx +b

so you first want to start off by looking for the equation with y being the sum. In this case, there is only one, so you don't have to do anymore work.

Answer:

x=2√41

Step-by-step explanation:

According to Pythagorean theorem:

14²=(4√2)²+x²

x²=14²-32=164

x=√164=2√41

Answer:

Equation has no solutions.

Step-by-step explanation:

7x + 28 - 6x - 18 = x + 5

7x + 10 - 6x = x + 5

x + 10 = x + 5

x + 10 - 10 = x + 5 - 10

x = x - 5

x - x = x - x - 5

0 ≠ - 5

Answer:

11.25

Step-by-step explanation:

the equation to find the area of a rectangle is A=w*l

A=2.5*4.5

A=11.25

Answer:

Objective Minimize 10x1 +15x2 + 12x3+18x4+15x5+ 21x6

The central total cost $ 17586 due to the number of central undergraduate students 1458 is very high.

The total minimum cost would $ 17586 +$260+ $300= $ 18146

Step-by-step explanation:

Let

X1 = # of undergraduate students from the East region,

X2 = # of graduate students from the East region,

X3 = # of undergraduate students from the Central region,

X4 = # of graduate students from the Central region,

X5 = # of undergraduate students from the West region, and

X6 = # of graduate students from the West region.

Then  the cost functions are

y1= 10x1 +15x2

y2= 12x3+18x4

y3= 15x5+ 21x6

According to the given conditions

The constraints are

x1 +x2 + x3+x4+ x5+ x6 ≥ 1500------- A

15X2 +18X4+21X6 ≥ 400---------B

21X6 ≥ 100

X6 ≥ 100/21

X6 ≥ 4.76

Taking

X6= 5

10X1 ≤ 500

X1 ≤ 500/10

X1≤ 5

18X4 ≥ 75

X4 ≥ 75/18

X4 ≥ 4.167

Taking

X4= 5

Putting the values

15X5+ 21X6 ≥ 300

15X5+ 21(5) ≥ 300

15X5+ 105 ≥ 300

15X5 ≥ 300-105

15X5 ≥ 195

X5 ≥ 195/15

X5 ≥ 13

Putting value of X6 and X4 in B

15X2 +18X4+21X6 ≥ 400

15X2 +18(5)+21(5) ≥ 400

15X2 +195 ≥ 400

15X2  ≥ 400-195

15X2  ≥ 205

X2  ≥ 205/15

X2  ≥ 13.67

Taking X2= 14

Now putting the values in the cost equations to check whether the conditions are satisfied.

y1= 10x1 +15x2

y1= 10 (5) + 15(14)= 50 + 210= $ 260

y3= 15x5+ 21x6

y3= 15 (13) + 21(5)

y3= 195+105= $ 300

x1 +x2 + x3+x4+ x5+ x6 ≥ 1500

5+14+x3+5+13+5≥ 1500

x3≥ 1500-42

x3≥ 1458

y2= 12x3+18x4

y2= 12 (1458)  + 18 (5)

y2= 17496 +90

y2= $ 17586

The cost can be minimized if the number of students from

                                 Undergraduate         Graduate

East Region              X1≤ 5                            X2  ≥ 13.67

Central                      X3≥ 1458                   X4 ≥ 4.167

West                          X5 ≥ 13                          X6 ≥ 4.76

This will result in the required number of students that is 1500

Constraints:

East Undergraduate must not be greater than 5

East Graduate must not be less than 13

Central Undergraduate must  be greater than 1458

Central Graduate must  be greater than 4

West Undergraduate must  be greater than 13

West Graduate must  be greater than 4

The central total cost $ 17586 due to the number of central undergraduate students 1458 is very high.

The east region has a least cost of $260 and west region has a cost of $300.

The total minimum cost would $ 17586 +$260+ $300= $ 18146

Answer:

Its D

Step-by-step explanation:

Using the binomial distribution, it is found that the mean and the standard deviation of X are given as follows:

[tex]\mu_X = 3, \sigma_X = 0.87[/tex]

The expected value of the binomial distribution is:

[tex]\mu_X = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sigma_X = \sqrt{np(1-p)}[/tex]

In this problem, the proportion and the sample size are given as follows:

Hence, the mean and the standard deviation are given by:

[tex]\mu_X = np = 4(0.75) = 3[/tex]

[tex]\sigma_X = \sqrt{np(1-p)} = \sqrt{4(0.75)(0.25)} = 0.87[/tex]
