Answer: 3 lessons

Step-by-step explanation:

Matt starts swimming lessons on Day 5.

He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:

First lesson = Day 5

Second lesson = Day 5 + 10 days = Day 15

Third lesson = Day 15 + 10 days = Day 25

Fourth lesson = Day 25 + 10 days= Day 35

<em>He therefore only went for 3 lessons because the 4th lesson was after Day 30. </em>

Find the range. 4.7 6.3 5.4 3.2 4.9 3.1 –3.1 9.5 –9.5
WINSTONCH [101]

Answer:

The range is 19

Step-by-step explanation:

First, you have to order the numbers from least to greatest:

-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5

Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:

9.5 - (-9.5)= 19

So, the range is 19

A regular assignment has 15 sides.Calculate the size of each interior angle
MariettaO [177]

Answer:

The measure of an interior angle of a regular 15-gon is 120°.

Step-by-step explanation:

We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.

Thus,

The number of sides n = 15

Hence,

Using the formula to determine the measure of an interior angle of a regular 15-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 15

(15 - 2) × 180 = 15 × interior angle

13 × 180 = 15 × interior angle

Interior angle = (10 × 180) / 15

                      = 1800 / 15

                      = 120°

Therefore, the measure of an interior angle of a regular 15-gon is 120°.

a pot of water starts at 68 degrees it is put on stove where it heats at a rate of 4 degrees per minute how long will it take to
Vladimir79 [104]
Y=68+4x
100=68+4x
-68=-68
32=4x
Divide both sides by 4 
x=it will take 8 min. for the water to reach 100 degrees
y=total degrees 
x=#  of minutes
