bob eats 6 apples in 2 days. how many days will it takes to eat a basket of apples containing 51 apples?

Ilia_Sergeevich [38]

If he eat 6 apples in 2 days so we can say he eat 3 apple in 1 day so if we want to know in how many days he can eat 51 apple you can say 51 ÷ 3= 17 also we can say 1day / 3 apples = ? days / 51 apples ⇒ 51×1 / 3 = 17 so he can eat 51 apples in 17 days :))))

A particular airport has beacons on the ground 6 km out from the start of each runway. An airplane is directly over this beacon

hodyreva [135]

Answer:

6.06 km

Step-by-step explanation:

The information given in the question can be represented by the three sides if a right angled triangle.

Let the direct line from the airplane to the start of the runway be represented by x. So that applying the appropriate trigonometric function, we have;

Cos θ = $\frac{adjacent}{hypotenuse}$

Cos $8^{o}$ = $\frac{6}{x}$

0.9903 = $\frac{6}{x}$

⇒ x = $\frac{6}{0.9903}$

= 6.0588

x = 6.06 km

The direct line from the airplane to the stat of the runway is 6.06 km.
