After training for and running a marathon, an athlete wants to reduce her daily run
by half each day. The marathon is about 26 mi. How many days will it take after the
marathon before she runs less than a mile a day? Show your work.

Answers

Answer 1

Answer:

6 days

Step-by-step explanation:

This question becomes much easier when written out per day (shown below). The question tells us that she is reducing her run by half every day, so all we need to is divide the previous day by 2 to get the current day. She starts out with 26 miles so this is our day 1 value.

Day 1 = 26 miles

Day 2 = 13 miles (26÷2=13)

Day 3 = 6.5 miles (13÷2=6.5)

Day 4 = 3.25 miles (6.5÷2=3.25)

Day 5 = 1.625 miles (3.25÷2=1.625)

Day 6 = 0.8125 miles (1.625÷2=0.8125)

We can see that by day 6, her total running amount is less that 1 mile, so the final answer is 6 days.

Suppose you deposit $200 in a savings account that earns 4% per year. Find the simple interest earned in 2 years. Then find the total of principal plus interest.

Answers

9514 1404 393

Answer:

interest: $16account total: $216

Step-by-step explanation:

The amount of interest is given by the simple interest formula:

  I = Prt . . . . where P is the amount earning interest, r is the annual rate, t is the number of years

  I = $200·0.04·2 = $16.00

The simple interest earned in 2 years is $16.00.

__

The total of principal and interest is found by adding those values:

  $200.00 +16.00 = $216.00

The total amount is $216.00.

Step-by-step explanation:

Express 960% as a mixed number

Answers

Answer:

9 3/5

Step-by-step explanation:

When we see a percentage, we know that the base is 100. In other words, 960% is equal to 960/100

With this, its just a matter of transforming the improper fraction to a mixed number.

100 fits 9 times in 960 so there will be 9 wholes

the remaining 60/100 can be simplified to 3/5 through this process:

60/100 = 6/10 = 3/5

Answer:

9 3/5

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

960% = 960/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As 960 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(960,100) = 20. So,

(960÷20)/(100÷20) = 48/5 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 960/100 is also equal to 9 3/5 when expressed as a mixed number.

Answers

Answer:

-17-4y

Step-by-step explanation:

You just have to add the numbers:

-13+7-11=-17

=17-4y

The sum of the terms -13 + 7 and  - 11 -4y is -4y - 17.

What is the sum?

A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, a thousand, or a million.

Given:

-13 + 7 and  - 11 -4y

Calculate the sum of the expression as shown below,

(-13 + 7) + (-11 - 4y)

-13 + 7 - 11 - 4y  [In sum, the sign convention will be (+) + (-) = (-)]

Arrange the term as shown below,

-4y + 7 - 13 - 11

Apply the operation as shown below,

-4y + 7 - 24

-4y - 17

Thus, the sum will be -4y - 17.

Symmetric property of equality to show that 3a = 4b, then 4b = 3a?

What is symmetric property of equality?

The symmetric property of equality is a simple property that says we can interchange the sides of an equation without changing the truth-value of the equation. That is, if a = b, then b = a. Each side of the equation can be thought of as the mirror image of the other

We have the following information available from the question is:
