Here is the math, did it on paper, sorry it’s blue. just add parenthesis around the x in the second equation and add what x equals. then solve as PEMDAS.
Answer:
6/25 km in 1 min; or 0.24 km/min
Step-by-step explanation:
The info about Angel is not necessary.
Jayden runs 3 laps in 5 mins
Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.
Distance = rate x time
6/5 km = rate (5 min)
We want to isolate r (rate), so divide both sides by 5 min
6/5 km ÷ 5 min = r
6/5 km (1/5 min) = r
6/25 km/min = r (notice how the units worked out correctly to km/min)
So, Jayden runs 6/25 km in 1 min.
Answer:
$1.59 for a pint,
two dollars for a quart,
299 for a gallon
Step-by-step explanation:
Since, rate is used to compare different kinds of quantities and it is the ratio of the quantities,
Also, unit rate states the amount of first quantity corresponding to the unit amount of second quantity,
When we talk about the unit rates for a quantity,
Then it shows the price of the quantity per unit amount.
Thus, by the above explanation it is clear that,
The unit price for representing the price of juice would be,
$1.59 for a pint,
two dollars for a quart,
299 for a gallon.
Note : we do not consider 'one dollar for 12 ounces' a unit price because it is not the price per 1 ounce.
Just by estimating, 54% is a little over 1/2 of 168. You know by that, that neither A or B is close. The real answer is 90.72, so if your instructor wants you to round up, it would be D
