Sam counted his heartbeats while resting. His heart beat 220 times in 4 minutes. Sam's heart beat at the same rate for the 4 minutes.

Answers

The equation for the number of beats per minute is 55 beats per minute

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of beats be = A

Now , the value of A = 220 beats

The total time required for Sam to have 220 beats = 4 minutes

So , the number of beats of Sam in 1 minutes is calculated by

The equation will be

The number of beats of Sam in 1 minutes is = total number of beats  / total time required for Sam to have 220 beats

The number of beats of Sam in 1 minute is = 220 / 4

The number of beats of Sam in 1 minute is = 55 beats per minute

Therefore , Sam would have 55 beats every minute or 55 beats per minute

And for the period of 4 minutes , Sam would have

Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4

Number of beats for 4 minutes = 55 x 4

Number of beats for 4 minutes = 220 beats in 4 minutes

Hence , The equation for the number of beats per minute is 55 beats per minute

There is a sales tax of $24 on an item that costs $276 before tax. A second item costs $218.50 before tax. What is the sales tax on the second item?

Answers

We have to determine the tax rate first, from the first item


So, we must find what percent is $24 of $276.


24/276 * 100 = 8.7%


Now we will calculate the 8.7% tax on the second item with cost $218.50


0.087 * 218.50 = 19.00


So the sales tax on the second item is $19
