Which is a better estimate for the weight of a dresser?<br> 45 grams or 45 kilograms
STatiana [176]
45 grams is about 1/4 cup of water or maybe 1/4 cup of flour or uncooked rice would be 45 grams. Anyway it's not much.

Unless the dresser is made of paper, 45 grams is not enough. 45 kg though large (that's roughly 100 pounds if that's what you think in), the dresser might be found in the apartment where Sherlock Holmes lives. (The dresser is a piece of victorian furniture) it is much closer to what a modern dresser would weigh.

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of wh
aleksandr82 [10.1K]

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

A mountain climber is currently 77 feet above ground level on the side of a cliff. She is climbing at the rate of about 7
horrorfan [7]

The climber would be at a height of 224 meter.

<h3>How to calculate elevation ?</h3>

Elevation is simple to calculate. You must first determine the unit rate, which is determined by dividing the height by the passage of time, before merely multiplying it by the passage of time.

Given, the climber is currently at a heigh of 77 feet.

And she is climbing at the rate of 7 feet per min

thus as we know that unit rate= elevation÷ time

Given unit rate is 7 feet min-1

So 7= 77/time

On calculating further we get,

time = 11 minutes

Thus the climber can cover 77 feet in 11 min

So distance covered by the climber in 1 min is 77/11 = 7 feet

Therefore after 32 minutes the climber will cover 32×7= 224 feet.
