Answer:

Step-by-step explanation:

Assuming the percentages all add up to 100%, if monkeys make up 10%, then it'd be 10/100 or 1/10.

Flying against the wind, an airplane travels 3060 kilometers in 3 hours. Flying with the wind, the same plane travels 7560 kilom

cluponka [151]

Answer:

The speed of plane against wind S 1 = 1020 kmph And

The speed of plane with wind S 2 = 1260 kmph

Step-by-step explanation:

Given as :

The distance of airplane against the wind = D 1 = 3060 km

The time taken in against the wind = T 1 = 3 hours

The distance of airplane with the wind = D 2 = 7560 km

The time taken in with the wind = T 2 = 6 hours

Now, Speed of plane against the wind = $\frac{Distance}{Time}$

So, S 1 = $\frac{D 1}{T 1}$

Or, S 1 = $\frac{3060}{3}$ = 1020 kmph

Similarly

Speed of plane with the wind = $\frac{Distance}{Time}$

Or, S 2 = $\frac{D 2}{T 2}$

Or, S 2 = $\frac{7560}{6}$ = 1260 kmph

Hence The speed of plane against wind S 1 = 1020 kmph And

The speed of plane with wind S 2 = 1260 kmph Answer

Explain why the triangles are similar then find out the distance represented by x

elena55 [62]

Because the only difference between them is size so the basic form of the shape remains, having corresponding sides in proportion.

<h2>Explanation:</h2>

Two triangles are similar if the only difference between them is size. Put another way, the basic form of the shape remains. If this is true, then:

Corresponding angles are congruent
Corresponding sides are in proportion

Since you didn't provide any graph, I have attached two similar triangles below. As you can see they are right triangles. As we said, corresponding sides of similar triangles are in proportion, so it is true that:

$\frac{9}{3}=\frac{12}{4}=\frac{x}{5}=3 \\ \\ \therefore \frac{x}{5}=3 \\ \\ \therefore x=5(3) \\ \\ \therefore \boxed{x=15}$
