5 0

Answer:

0.065 g

Step-by-step explanation:

Given: 0.0645

Round the given decimal to 2 significant figures.

Round: To reduce the decimal digits which changes last digits.

If digits greater than 5 then previous digits increase by 1

If digit less than 5 then no change in last digit.

Round of 2 decimal place: Write two digits after decimal.

Significant figure: The number of digits from first digits 1 to 9 .

In the given decimal number. Number of digits after decimal is 4 and significant is 3

0.0645 Round off to 2 significant number.

0.0645 ⇒ 0.065 g

The unit of number doesn't change.

Danny's truck has a fuel tank with a capacity of 20 gallons of gas. The truck averages 17 miles per gallon of gas. The function
Fittoniya [83]

For this case we have the following function:

M (g) = 17g

Where,

g: number of gallons of gas

M (g): number of miles that Danny's truck travels

We know that the maximum capacity is 20 gallons of gas.

Therefore, the maximum distance the truck can travel is given by:

M (20) = 17 (20)

M (20) = 340

Thus, the domain of the function is:

0 \leq g \leq 20

The range of the function is:

0 \leq M(g) \leq 340

Answer:

A domain and range that are reasonable for the function are:

D. D: 0 ≤ g ≤ 20

R: 0 ≤ M (g) ≤ 340

Jamie has a piece of wood that is 6/8 inches long. He cuts the wood into pieces that are ¼ inches long. How many pieces of wood
pashok25 [27]
Answer: three pieces.

The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.

Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.

1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.
