Answer:

796

Step-by-step explanation:

We have given the number 756, 37.2, 0.83, 2

We have to find the sum of the number to the correct number of significant figure

So the sum 756+37.2+0.83+2=796.03

As the maximum significant figure is 3 in the given numbers

So we have to write the answer up to three significant figure

So answer will be 796

Plant A is 16/3 feet tall. This is 4/5 as Plant B. How tall is Plant B?
bearhunter [10]

Plant B is \frac{20}{3} feet tall.

Step-by-step explanation:

Given,

Height of plant A = \frac{16}{3}\ feet

This is 4/5 of height of plant B.

Let,

x be the height of plant B.

\frac{4}{5}x=\frac{16}{3}

Multiplying both sides by \frac{5}{4}

\frac{5}{4}*\frac{4}{5}x=\frac{16}{3}*\frac{5}{4}\\\\x=\frac{80}{12}\\\\x=\frac{20}{3}

Plant B is \frac{20}{3} feet tall.
