So,

32 fl. oz. costs $2.56.  To find the unit rate, we need to divide 2.56 by 32.

This is a special case, because we notice that 256 and 32 are perfect powers of 2.

\frac{256}{32} = \frac{2^8}{2^5} =2^3=8

The cranberry juice costs 8 cents per fluid ounce.

Unit rate is (cost) per 1 unit
the unit is fluid oz
'per' is fraction
cost/1unit
so we do
2.56/32
divide completely
2.56/32=0.08/1
the unit rate is $0.08 per oz

A tree casts a shadow 27 m long. At the same time, the shadow cast by a 66-cm tall statue is 56 cm long. Find the height of the
Nata [24]
\frac{height _{1} }{shadow_{1}} =  \frac{height _{2} }{shadow_{2}}

\frac{height _{1} }{27m} = \frac{66cm}{56cm}

\frac{height _{1} }{2700cm} = \frac{66cm}{56cm}

2700*66=56*h _{1}

178200=56h _{1}

3182.1cm=h _{1}

\frac{3182.1cm}{1000cm} = 3.2m

height:3.2m

Bulan rows on a crew team. Her team rows their boat at a split (rate) of 2 min/500 m.
notka56 [123]

Answer:

250

Step-by-step explanation:

If Bulan's team rows their boat at a rate of

2

minutes per

500

meters, they row at a rate of

1

minute per

250

meters. We know this because

1

minute is

1

2

of

2

minutes, and in this time, they will have to have rowed

1

2

the distance they would row in

2

minutes (

500

m).

1

2

of

500

is

250

.

So, we now have the rate in min/m.

If, every

1

minute, Bulan's team rows

250

meters, this means that every

250

meters, they have rowed for

1

minute.

Bulan's team's rowing rate in m/min is

250

m/

1

min.
