Kathy measured her finger using a ruler with centimeters. Then she measured the same finger with a ruler using millimeters. Can

Kathy compare the two measurements?
Mathematics
1 answer:
boyakko [2]3 years ago
3 0

Answer:

<h2>Kathy cannot compare the two measurements</h2>

Step-by-step explanation:

This problem seeks to tests our understanding of measurements and units

Kathy cannot compare the two measurements because the two units of measurement are not the same.

Now centimetres  is 10 times bigger than millimetres.

What Kathy can actually do is to convert from one unit to another, that is from centimetres to millimetres.

<em>Since the units are not similar Kathy cannot compare them but she can convert from one to the other</em>

Problem 18)

The distance from J to L is 30 units. We can count out the number of spaces or do subtraction to get 30-0 = 30. I subtracted the number line coordinate of J and L. The result is positive as distance is never negative.

Take 2/3 of this value to get (2/3)*30 = 20 which means that we start at J and add on 20 units to get 0+20 = 20

So the final answer is 20, which is where this point is located on the number line.
----------------------------------------------------------------
Problem 19)

The distance from A to B is 3 units because |-5-(-2)| = |-5+2| = |-3| = 3

Double this value to get 2*3 = 6

Now add 6 units to the coordinate of point A to get
-5+6 = 1

The location of this point is at 1 on the number line.
----------------------------------------------------------------
Problem 20)

From J to I, or vice versa, we travel 5 units. 

Multiply this by 1.5 to get 1.5*5 = 7.5

So we subtract 7.5 units from 0 (the coordinate of point J) getting us 0-7.5 = -7.5

Final Answer: -7.5
Note: this is the midpoint of -10 and -5 on the number line

Suzette ran and biked for a total of 34 mi in 3.5 h. Her average running speed was 6 mph and her average biking speed was 12.5 m
sveticcg [70]

Answer:

The speed of an object is the rate of distance traveled over time. Suzette ran for 1.5 hours, and she biked for 2 hours.

Given that: Speed is calculated as: Make Distance the subject Average running speed = 6 mph for x hours implies that: Average biking speed = 12.5 mph for y hours implies that: So, the total distance is: The total distance is 34 miles. So, we have: The total time is 3.5h. So, we have: Make x the subject Substitute in Collect like terms Divide both sides by 6.5 Recall that: Hence, Suzette ran for 1.5 hours, and she biked for 2 hours.'

x=3.5-y

x-3.5-2

x=1.5

katen-ka-za [31]

Answer:

Option D) 5.4%

Step-by-step explanation:

we know that

$75.74 ----> represent the 100%

so

using proportion

Find the percentage that the amount of the customer's water bill increase

Let

x -----> the percentage that increase

$75.74/100%=($79.86-$75.74)/x

$75.74/100%=($4.12)/x

x=100*4.12/75.74

x=5.4%
