Based on the chart on the left, you can see there are 2 dragonflies with the lengths of 3 1/4 inches. Therefore, 2 marks should be made over the 3 1/4 inches spot on the line plot.

Hope this helps

Brainliest would be appreciated

Before going to school, Eudora ran from her home to a secret laboratory at an average speed of 12 km. Since she was running late

Brrunno [24]

Answer:

Eudora spent 0.5 hours in running and 1.5 hours flying using her jet-pack.

Step-by-step explanation:

Let x represent time spent in running.

We have been given that the entire trip took 2 hours, so time spent in flying the jet-packs would be $2-x$ .

We know that distance is equal to speed times time.

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

Eudora ran from her home to a secret laboratory at an average speed of 12 km, so distance traveled by running would be $12x$ .

Eudora took one of her jet-packs and flew to her school at an average speed of 76 km, so distance covered by jet-packs would be $76(2-x)$ .

We are told that Eudora traveled a total distance of 120 km. We can represent this information in an equation as:

$12x+76(2-x)=120$

$12x+152-76x=120$

Combine like terms:

$-64x+152=120$

$-64x+152-152=120-152$

$-64x=-32$

Divide both sides by $-64$ :

$\frac{-64x}{-64}=\frac{-32}{-64}$

$x=0.5$

Therefore, Eudora spent 0.5 hours in running.

Upon substituting $x=0.5$ in expression for time spent in flying jet-packs, we will get:

$2-x\Rightarrow 2-0.5=1.5$

Therefore, Eudora spent 1.5 hours flying using her jet-pack.

Alaska has the land area of about 1,700,000 km² Florida has a land area 1/10 the size of Alaska what is the land area of Florida

Sergeeva-Olga [200]

Ans=170,000km^2 Florida is 1/10 of size . So :1/10 times 1,700,000 . Basically if you imagine Alaska as a pizza . You would cut in ten slices ( because number ten in 1/10) and you would take once slice ( because the number one in 1/10)
Am I'm clear? Hope this helps!
