#17. The height, H metres, of a certain species of Fir

olya-2409 [2.1K]

Answer:

The approximated height of the tree is of 112 meters.

Step-by-step explanation:

The height of a tree with a base diameter of d meters is approximated by the following formula:

$h = 35d$

In this question:

Base diameter of 3.2m, so $d = 3.2$ , and the height is in meters.

$h = 35d = 35(3.2) = 112$

The approximated height of the tree is of 112 meters.

Solve. 2(2z – 4) = 4

Oxana [17]

Answer:

$z = 3$

Step-by-step explanation:

1) Divide both sides by 2.

$2z - 4 = \frac{4}{2}$

2) Simplify 4/2 to 2.

$2z - 4 = 2$

3) Add 4 to both sides.

$2z = 2 + 4$

4) Simplify 2 + 4 to 6.

$2z = 6$

5) Divide both sides by 2.

$z = \frac{6}{2}$

6) Simplify 6/2 to 3.

$z = 3$

therefor, the answer is z = 3.
