Sandra has ribbons that are 2/6 meter 3/4meter and 4/9 meter long .She needs to use the ribbon longer than 2/3meter to make a bo

timurjin [86]

Answer:

3/4 meter

Step-by-step explanation:

Need Common denominators to compare size

2/6 3/4 4/9 which is longer than 2/3?

2/6 compared to 2/3. 2/6 = 2/6 and 2/3 = 4/6.

2/6 < 2/3 so 2/6 is too short

3/4 compared to 2/3 3/4 = 9/12 and 2/3 = 8/12

3/4 > 2/3 so 3/4 is longer than 2/3

4/9 compared to 2/3 4/9 = 4/9 and 2/3 = 6/9

4/9 < 2/3 so 4/9 is too short

mylen [45]

Answer:

The average speed is:

$\var{v}=75\: miles/h$

Step-by-step explanation:

The average speed equation is given by:

$\var{v}=\frac{\Delta x}{\Delta t}$

Were:

Δx is the displacement (225 miles)
Δt is the change in time (3 hours)

Then we have:

$\var{v}=\frac{225}{3}$

$\var{v}=75\: miles/h$

I hope it helps you!

A dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours. At this constant rate, how long does i

Novosadov [1.4K]

Answer:

$\frac{4}{5}$ hour

Step-by-step explanation:

Let x represent time taken by dog to run the 1 and three tenths -mile state fair race.

We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.

We will use proportions to solve our given problem as:

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

We will equate both speeds as:

$\frac{1\frac{3}{10}}{x}=\frac{3\frac{1}{4}}{2}$

$\frac{\frac{13}{10}}{x}=\frac{\frac{13}{4}}{2}$

$\frac{13}{10\cdot x}=\frac{13}{4\cdot 2}$

Cross multiply:

$13\cdot 10\cdot x=13\cdot 4\cdot 2$

$10\cdot x=4\cdot 2$

$\frac{10\cdot x}{10}=\frac{4\cdot 2}{10}$

Therefore, it will take $\frac{4}{5}$ hour to complete $1\frac{3}{10}$ mile state fair race.
