C.
3.48 × 10^5 g/min

D.
3.48 × 10^3 g/min

Answers

Answer 1

Answer: $1g=1000mg\to1mg=0.001g\n\n1min=60s\to1s=(1)/(60)min\n\n5.8*10^6\ mg/s=5.8*10^6*(0.001)/((1)/(60))\ g/min\n\n=5.8*10^6*0.001*60\ g/min=(5.8*60)*(10^6*0.001)\ g/min\n\n=348*10^3\ g/min=\boxed{3.48*10^5\ g/min}\n\nAnswer:\boxed{C}$

A fruit stand has to decide what to charge for their produce. They decide to charge $5.30 for 1 apple and 1 orange. They also plan to charge $14 for 2 apples and 2 oranges. We put this information into a system of linear equations.Can we find a unique price for an apple and an orange?

Answers

Answer:

We cannot find a solution to the system of equations.

a+b = 5.30

2a + 2b = 14

Step-by-step explanation:

Let a = the price of an apple

let b = price of an orange

a+b = 5.30

2a + 2b = 14

Multiply the first equation by 2

2a+ 2b = 10.60

Subtract the second equation

2a+2b = 10.60

-2a+2b = 14

---------------------------

0 = -3.40

This is never true so there is no solution

An easier way is converting yards to inches (36 inches in a yard)

So converting will give you 27 in by 18 inches
(3/4 of 36) and (1/2 of 36) now it will be easier to multiply

So 27 • 18 = 486 square inches
