Joanna ran a mile in physical education class. After resting for one hour her heart rate was 60 beats per minute. If her heart rate decreased by2/5, what was her heart rate immediately after she ran the mile?

Answers

Answer 1

if her heart rate decreased by 2/5ths and became 60, that means 60 is 3/5th. divide 60 by 3 to find out how much one fifth is. 60/3 = 20, so if 1/5th is 20, that makes 2/5th 40. Add 40 and 60 to get 100, which is your answer.

Answers

The answer is C. because 1.5 is the height while x is next to it to show the multiplication of years to height

it grows 1.5 feet per year so multiply that by number of years (x)

1.5x

it started at 2 feet tall

so you would have 1.5x +2 ≥14

Answer is C. 1.5x + 2 ≥ 14

A bag contains 4 red marbles and 6 blue marbles. Brandon selects one marble from the bag. Without replacing the marble he then selects a second marble. What is the probability that he first selects a blue marble and then selects a red marble?

Answers

Answer:D) 4/15

Step-by-step explanation:

6/10•4/9=4/15 mark brainliest please.

The probability that he first selects a blue marble and then selects a red marble is 4/15.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

The number of red marbles in bag=4

The number of blue marbles in bag=6

The total number of marbles in bag are 4+6=10

The probability of selecting a blue ball is 6/10

The probability of selecting a red ball without replacement is 4/9

So the probability that he first selects a blue marble and then selects a red marble

6/10×4/9

24/90

4/15

Hence the probability that he first selects a blue marble and then selects a red marble is 4/15.

when 18 is subtracted from six times a certain number,the result is -42. what is the number?

Answers

Let x be the number.

Then;

6x-18=-42 (solve for x now)
6x=-42+18
6x=-24
x=-4

Therefore, this number would be -4.

Hope I helped :)

To start off, you want to create an equation. 18 subtracted six times from a certain number (let's use a variable 'x') would look like: 6x - 18.
6x - 18 = -42

Next, isolate the variable by adding 18 to both sides.
6x - 18 = -42
+ 18 + 18
6x = -24

Lastly, solve for x.
6x/6 = -24/6
x = -4

How many solutions does this equation have?

So your variable is v. Let's solve for v.

7v = 7v + 10. subtract 7v from both sides

A truck can be rented from Company A for $120 a day plus $0.50 per mile. Company B charges $30 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

120 + 0.5x = 30 + 0.8x

90 = 0.3x

x = 300

The charges of both companies will be same if truck is driven 300 miles per day.

It is required to find the number of miles in a day.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

Let the truck is driven X miles per day

Charges of company A will be = $120 + $0.50x

Charges of company B will be = $30 + $0.80

Let us find out value of X when charges of both companies are same

Now the following equation should be made

$120 + $0.50x = $30 + $0.80

$120 - $30 = $0.80x - $0.50x

$90 = $0.30x

x = 300 miles.

Therefore, the charges of both companies will be same if truck is driven 300 miles per day.

The E. coli bacterium is about 5×10^−7 meters wide. A hair is about 1.7×10^−5 meters wide. Which is wider, the bacterium or the hair?

The bacterium

Answers

The hair is wider than the bacterium.

The E. coli bacterium is about 5×10⁻⁷ meters wide, and a hair is about 1.7×10⁻⁵ meters wide.

To compare the widths of the bacterium and the hair, we can convert both measurements to the same unit.

Let's convert the width of the bacterium to micrometers, which is 5×10⁻¹³ micrometers.

The width of the hair is 1.7×10⁻³ micrometers.

Comparing the two measurements, we can see that the hair is wider than the bacterium.
