The ratio of the areas of two rectangle is 3 to 7. In the area of the large rectangle is 84 square feet, what is the area of the

goldenfox [79]

A. The unknown variable is the area of the smaller rectangle.

B. 3/7=x/84

$\frac{3}{7}=\frac{x}{84}\\\frac{3*12}{7*12}=\frac{x}{84}\\\frac{36}{84}=\frac{x}{84}\\\frac{36}{84}*84=\frac{x}{84}*84\\36=x$

C. No. 12 does not equal 15.

$\frac{3}{7} \neq \frac{15}{28}\\\frac{3*4}{7*4}\neq\frac{15}{28}\\\frac{12}{28}\neq\frac{15}{28}\\\frac{12}{28}*28\neq\frac{15}{28}*28\\12\neq15$

A. A product has a probability of 60% showing up in warehouse A, and 80% in warehouse.

Alex_Xolod [135]

Answer:

100%

Step-by-step explanation:

Probability of a product showing up in warehouse A =60%

Probability of a product showing up in warehouse B = 80%

Probability of 2 product showing up in warehouse A is

Probability of 1 product showing up in A and probability of 1 product showing up in A

A n A = 60% x 60% = 0.6 x 0.6 = 0.36 =36%

Probability of 2 product showing up in warehouse B is

Same as above

Probability of 1 product showing up in B and probability of 1 product showing up in B

B n B = 80% x 80% = 0.8 x 0.8 = 0.64= 64%

Probability of 2 product showing up in same warehouse is define as

Probability of 1 product showing up in A and probability of 1 product showing up in A or

Probability of 1 product showing up in B and probability of 1 product showing up in B

(AnA) U (BnB) =

36% + 64% = 0.36 + 0.64= 1

11. You expect to have the given amount in an account with the given terms. Find how much you can withdraw periodically in order

Orlov [11]

This is a question on Present Value of Annuity and we seek the periodic withdrawal.

$\begin{gathered} F\text{VA}=\text{PMT(}\frac{(1+\frac{i}{m})^{nm}-1}{\frac{i}{m}}) \\ \text{Therefore, PMT=}\frac{FVA}{(\frac{(1+\frac{i}{m})^{nm}-1}{\frac{i}{m}})} \end{gathered}$

where:

FVA = Future value of annuity

PMT = Periodic Withdrawal

i = interest/discount rate

n = no of years

m = no of compundings per interest period

$\text{PMT=}\frac{300000}{(\frac{(1+\frac{0.0445}{365})^{22\times365}-1}{\frac{0.0445}{365}})}=22.01$

PMT = $22.01
