Answer:
a. mass is to kilogram.
Answer:
The length of rectangular is increasing at a rate 0.5714 meters per hour.
Step-by-step explanation:
We are given the following in the question:
Initial dimensions of rectangular box:
Length,l = 10 m
Width,w = 7 m

We have to find the rate of increase of length.
Area of rectangle =

Differentiating we get,

Putting values, we get,

Thus, the length of rectangular is increasing at a rate 0.5714 meters per hour.
Answer: 
Step-by-step explanation:
Pythagorean theorem:
, where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.


Since we don't know what
is, we're going to isolate it by subtracting 81 on both sides

We have to square root both sides in order to find out b (or x in the problem).

When you put this on a calculator it would result in
which is the answer d in the problem.
Answer:
b.) area of triangle= 1/2 base x height
A to B(base)= 8
height= 8
8 × 8= 64
64÷ 2= 32
area of the triangle= 32
I think this is correct aha
Equilateral = all sides are same
side length = 8 3/4 ÷ 3
= 35/4 ÷ 3
= 35/4 × 1/3
= 35/12
