Maddox McDonald A caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes. How fast does the caterpillar move
harina [27]

Answer: 2/3 feet per minute

Step-by-step explanation:

From the question, we are informed that a caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes.

The rate at which the caterpillar move in feet per minute will be:

= 4 2/3 ÷ 7

= 14/3 ÷ 7

= 14/3 × 1/7

= 14/21

= 2/3 feet per minute

Viktor [21]

<u>Given:</u>

The angle of elevation from the point on the ground to the top of the tree is 34° and the point is 25 feet from the base of the tree.

We need to determine the height of the tree.

<u>Height of the tree:</u>

Let the height of the tree be h.

The height of the tree can be determined using the trigonometric ratio.

Thus, we have;

tan \ \theta=\frac{opp}{adj}

Substituting the values, we get;

tan \ 34^{\circ}=\frac{h}{25}

Multiplying both sides by 25, we have;

tan \ 34^{\circ} \times 25=h

 0.6745 \times 25=h

       16.8625=h

Rounding off to the nearest tenth of a foot, we get;

16.9=h

Thus, the height of the tree is 16.9 feet.

Hence, Option B is the correct answer.
