D. 0.15

Answers

Answer 1
Answer: When comparing decimals, you have to compare each place value. Begin with the tenths place and compare each number that occupies that place. If they are the same, move to the hundredths place and compare. When you reach a place value where the numbers are not the same, compare them. The larger number in that place value is the larger number.

For your choices, when we look at the tenths place, we see that one of the numbers is 0 and all the other numbers have a higher number so we don't have to go any further...

c)0.015 is the smaller number

Answer:

7250

Step-by-step explanation:

This is like the pythagorean theorem. So you add A^2,B^2, and C^2. So 25^2 + 60^2 + 55^2. 625 + 3600 + 3025. That equals to 7250.

The linear function y = 1.2x represents Alberto’s speed, y, in meters per minute, when his stride rate is x steps per minute.Explain what the slope and y-intercept of the linear model represent in the context of the situation.

Answers

Answer with explanation:

The linear function is given by:

              y=1.2x

where y represents Alberto's speed in meters per minutes.

when his stride rate is x steps per minute.

We know that for any linear function of the type:

  y=mx+c

m represents the slope and c represents the y-intercept of the function.

  • Here m=1.2 and c=0

i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.

  • and the y-intercept represents the speed of Alberto when he took 0 steps i.e when x=0.

It represents that his speed is 0 meter per minutes when he did not took any step.
The slope is the rate in which he is moving and the y-intercept is where he started (at 0 seconds and 0 meters).
