There are 15.748 inches in 40cm. Can I please have brainlest?

Step-by-step explanation:

Answer:

40cm

Step-by-step explanation:

If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.

** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.

Three times the difference of a number and 5 is the same as twice the number, decreased by 3. Find the number

Answers

Answer:

x = 12

Step-by-step explanation:

3 (x-5) = 2x - 3

3x -15 = 2x - 3

x-15 = -3

x = 12

check:

21 = 21

The number as decribed (Three times the difference of a number and 5 is the same as twice the number, decreased by 3) in the question is; 12

According to the question;

Three times the difference of a number and 5 is the same as twice the number, decreased by 3.

The word problem can be written and solved as follows;

3(x - 5) = 2x -3

3x -15 = 2x -3

3x -2x = 15 -3

x = 12

What slope is perpendicular to:
m = 5/8

Answers

the perpendicular slope would be m=-8/5

The slope that is perpendicular to m = 5/8 is given by; m' = -8/5

When dealing with slope - intercept form of equation of a line, the general equation is;

         y = mx + c

where;

m is the slope

c is the y-intercept

Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is;  m' = -1/m

Applying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?

Answers

Given:

Rita covered 1 mile in 15 minutes.

She covered 3 miles in 30 minutes.

To find:

The rate at which she is riding.

Solution:

Let y be the number of miles covered in x minutes.

Rita covered 1 mile in 15 minutes. So, the point is (15,1).

She covered 3 miles in 30 minutes. So, the point is (30,3).

Slope of the line:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-1}{30-15}[/tex]

[tex]m=\dfrac{2}{15}[/tex]

Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.
