Answer:

  1. temperature is decreasing as time passes
  2. x-axis
  3. hot drink temperature (°C)

Step-by-step explanation:

1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.

__

2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.

__

3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.

What is the area of the sector below
kumpel [21]

Answer:

26.17 cm²

Step-by-step explanation:

Applying,

A = πr²∅/360................. Equation 1

Where A = Area of the sector, r = radius of the circle the sector was formed from, ∅ = angle subtends by the sector at the center of the circle , π = pie.

From the question,

Given: r = 5 cm, ∅ = 120°, π = 3.14

Substitute these values into equation 1

A = 3.14(5²)(120)/360

A = 26.17 cm²

Hence the area of the sector is 26.17 cm²

inn [45]

Answer:

Estimate = 3400 books

Step-by-step explanation:

Given that:

Books read by students.

Kindergarten 247

First grade 385

Second grade  1347

Third grade 1549

We have to round the each number to nearest hundred.

247 rounded to the nearest hundred is 200.

385 rounded is 400

1347 rounded is 1300

1549 rounded is 1500

Total = 200 + 400 + 1300 + 1500 = 3400

Hence,

Estimate = 3400 books

Please help! It’s not too hard! Will mark brainliest!
Yuki888 [10]

Step-by-step explanation:

In the first part, he was travelling with twice the speed, or Vs, for distance

48 - d, for 2 hours.

speed = distance/time

distance = speed * time

First part :

48 - d = 2V * 2

⇒d + 4V = 48  

Second part:

d = V * 2

⇒d = 2V  

Substitute 2s for d in equation 1.

2s + 4s = 48

6s = 48

s = 8

The speed in the second part is 8 mph.

<u>The speed in the first part is 2s = 2(8) = 16</u>

I hope this helps
