What is 5.8×10^6 mg/s in grams per minute? A. 9.7×10^9 g/min B. 9.7 × 10^7 g/min C. 3.48 × 10^5 g/min D. 3.48 × 10^3 g/min.

Luda [366]

1 second = 5.8x10^6 mg
60 seconds = 5.8x10^6 x 60 = 3.48x10^8 mg
(i.e 3.48x10^8 mg/minute)

1000 mg = 1 g
3.48x10^8 mg = 3.48x10^8/1000 = 3.48x10^5 g

Therefore, 5.8x10^6 mg/s = 3.48x10^5 g/min

Each hotdog cost $1.50 and sodas cost $.50. At the end of the day you made a total of $78.50.You sold a total of 87 hot dogs and

Bond [772]

Answer:

The number of hot dogs sold was 35 and the number of sodas sold was 52

Step-by-step explanation:

Let

x ----> the number of hot dogs sold

y ----> the number of sodas sold

we know that

$x+y=87$

$x=87-y$ ----> equation A

$1.50x+0.50y=78.50$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$1.50(87-y)+0.50y=78.50$

solve for y

$130.50-1.50y+0.50y=78.50$

$1.50y-0.50y=130.50-78.50$

$y=52\ sodas$

<em>Find the value of x</em>

$x=87-52=35\ hot dogs$

therefore

The number of hot dogs sold was 35 and the number of sodas sold was 52
