Lucy and JoJo need to make 140 cupcakes for the school dance,

Pepsi [2]

Answer:

56 cupcakes

Step-by-step explanation:

First, I convert 3/5 to a percent because I prefer to work with percents:

3/5 = 0.6 = 60%

Then, subtract 60% from 100% for the percent of the total cupcakes that JoJo needs to make:

100 - 60 = 40%

Finally, multiply the total cupcakes by the percent as a decimal:

140 × 0.4 = 56

An object is traveling at a steady speed of 10 and one tenth km/h. How long will it take the object to travel 4 and nine tenths

My name is Ann [436]

Answer:

Estimated Answer= $\frac{1}{2} hour$

Exact Answer= $\frac{49}{101} hr$

Step-by-step explanation:

Steady speed of the object =10 and one tenth km/h = $10\frac{1}{10} km/hr$

Distance to be Covered=4 and nine tenths km = $4\frac{9}{10}$ km

To the nearest integer,

Steady speed of the object = 10 km/hr

Distance=5km

$Time Taken = \frac{Distance}{Average Speed}$

= $=\frac{5}{10} =\frac{1}{2} hr$

The estimated answer is 1/2 hr.

Next, we determine the exact answer.

$Time Taken = \frac{Distance}{Average Speed}\\ = 4\frac{9}{10} \div 10\frac{1}{10}\\=\frac{49}{10} \div \frac{101}{10}\\=\frac{49}{10} X \frac{10}{101}\\=\frac{49}{101} hr$

The exact time taken is $\frac{49}{101} hr$
