Alex usually runs for 21 hours a week, training for a marathon. If he is unable to run for 3 days, describe how to find out how many hours of training time he loses, and write the appropriate integer to describe how it affects his time.

Answers

Answer 1
If he runs for 21 hours per week, how many hours does he run per day? There are 7 days in a week, so this would be 21/7. Then if he doesn't run for three days, you need to multiply this by 3.

Which of the following would be equivalent to 11 to the 8th power over 11 to the 3rd power?

A)11 to the 7th power over 11 to the 7th power
B)11 ⋅ 114
C)11 to the 0 power over 11 to the 5th power
D)110

Answers

none of the above. 11^8/11^3 is 11^5 since you will just subtract exponents. The numerical value is 161051
although you should have an option that either is 11^5 or equals 11^5 like 11^15/11^10 for example
Answer:

Option: B is the correct answer.

                          [tex]B)\ 11\cdot 11^4[/tex]

Step-by-step explanation:

We are given a numerical expression as:

    11 to the 8th power over 11 to the 3rd power.

i.e. mathematically it is given by:

[tex]\dfrac{11^8}{11^3}[/tex]

Now, we know that if the numerator and the denominator terms are power terms such that both the terms are of same base then the resultant is the same base and the exponent of the base is: exponent of numerator minus exponent of denominator.

i.e.

[tex]\dfrac{a^m}{a^n}=a^{m-n}[/tex]

Here we have:

[tex]a=11,\ m=8\ and\ n=3[/tex]

Hence, we get:

[tex]\dfrac{11^8}{11^3}=11^{8-3}[/tex]

i.e.

[tex]\dfrac{11^8}{11^3}=11^5[/tex]

Now, this could also be written as:

[tex]\dfrac{11^8}{11^3}=11\cdot 11^4[/tex]

( since,

[tex]a^m\cdot a^n=a^{m+n}\\\\i.e.\\\\11^1\cdot 11^4=11^{4+1}=11^5[/tex] )

             

Tom went on a bike ride to the store 3 miles away if it took Time 1/2 hour to get there in 2/3 of an hour to get back what was his average rate of speed miles per hour for the entire trip

Answers

Sent a picture of the solution to the problem (s).

In order to achieve the times that he did in going to and from the store, Tom went at an average speed of 5.14 miles per hour.

The store was 3 miles away which means that the distance of the entire trip is:

= Distance going + Distance coming

= 3 + 3

= 6 miles in total

The time he took was:

= Time going + Time coming

= 1/2 hours + 2/3 hours

= 0.5 + 0.67

= 1.17 hours

His average speed for the entire journey is:

= Distance / Time

= 6 / 1.17

= 5.14 miles per hour

In conclusion, Tom's average speed was 5.14 miles per hour.

Suppose you have developed a scale that indicates the brightness of sunlight each category in the table is five times brighter than the category above it for example a day that is dazzling is five times brighter than a day that is radian how many times brighter is a dazzling day then a dim day

Dim=2
Illuminated=3
Radiant=4
Dazzling=5

Answers

Use x= 1 as a reference for the dazzling level of Dim.
That is,
Dim = x
Illuminated = 5x
Radiant = 5(5x) = 25x
Dazzling = 5(25x) = 125x

Answer:  Dazzling is 125 times brighter than Dim.

Answer:

Basicly all you do is Multiply Dazzling 4 times by 5, so 5*5*5*5 and your answer is 125.

EXAMPLE ;

IF it was 2 times brighter you would count the catagories. There are 4. So you would do 2*2*2*2 and you answer is 16.

7.4p - 9.2p = -2.6 + 5.3

Answers

Simplify both sides of the equation.
-1.8p=2.7
Divide both sides by -1.8
p= -1.5
7.4p+-5.3-9.2p=-26

Simplify
7.4p + -5.3 + -9.2p = -26

Reorder the terms:
-5.3 + 7.4p + -9.2p = -26

Combine like terms: 7.4p + -9.2p = -1.8p
-5.3 + -1.8p = -26

Solve
-5.3 + -1.8p = -26

Solve for variable (p)

Move all terms containing (p) to the left, all other terms to the right.

Add (5.3) to each side of the equation.
-5.3 + 5.3 + -1.8p = -26 + 5.3

Combine like terms: -5.3 + 5.3 = 0
0.0 + -1.8p = -26 + 5.3
-1.8p = -26 + 5.3

Combine like terms: -26 + 5.3 = -20.7
-1.8p = -20.7

Divide each side by (-1.8)
p = 11.5

Simplify
p = 11.5

List three numbers that are divisible by 3, 4 and five

Answers

3*4*5=60
60*1=60
60*2=120
60*3=180

3 numbers are 60, 120, and 180
Final answer:

To find numbers divisible by 3, 4, and 5, we need to find common multiples of these three numbers. One example is 30, and other possible numbers include 60 and 90.

Explanation:

When we need to find numbers that are divisible by 3, 4, and 5, we can look for numbers that are common multiples of these three numbers. In other words, we need to find numbers that can be divided evenly by 3, 4, and 5 without any remainder. Let's take a look at the first few numbers and see if they satisfy this condition.

15: 15 is divisible by 3 (15 ÷ 3 = 5), divisible by 5 (15 ÷ 5 = 3), but not divisible by 4 (15 ÷ 4 = 3 remainder 3), so it is not a solution.20: 20 is not divisible by 3 (20 ÷ 3 = 6 remainder 2), not divisible by 4 (20 ÷ 4 = 5 remainder 0), but divisible by 5 (20 ÷ 5 = 4), so it is not a solution.30: 30 is divisible by 3 (30 ÷ 3 = 10), divisible by 4 (30 ÷ 4 = 7 remainder 2), and divisible by 5 (30 ÷ 5 = 6), so it is a solution.

From our analysis, we found that the number 30 is divisible by 3, 4, and 5. We can list two more numbers by finding common multiples of these three numbers.

Answers

1.) 1/6 Chance the letter will be D due to having 1 letter D out of 6 total leters
2.) 1/6 Chance of rolling a 7 due to having 6 total numbers and only one 7
3.) 10/52 Chance of pulling green due to only having 10 green marbles and 52 total marbles

Answer:

Probability that the chosen letter is d is [tex]\frac{1}{6}[/tex]Probability of rolling a 7 is [tex]\frac{1}{6}[/tex]Probability of picking a green is [tex]\frac{5}{21}[/tex]

Step-by-step explanation:

Probability of choosing d in the word "combed"

Given:

Alphabet: d

Word: combed

First, we note down the length of the word "combed";

The length is 6 characters

The we check the number of occurrence of d in the word "combed"

Occurrence of d = 1

Probability is then calculated as;

Probability of choosing d = [tex]\frac{Number of Occurrence}{Total Observation}[/tex]

By Substitution; Probability = [tex]\frac{1}{6}[/tex]

Probability of rolling a 7 in a cube of side numbers 2,4,8,9,4, and 7

Given:

Roll number = 7

Sample Space= {2,4,8,9,4, 7}

Sample Size, n(S) = 6

We check the number of occurrence of 7 in the sample space

Number of occurrence = 1

Probability is then calculated as;

Probability of rolling a 7 = [tex]\frac{Number of Occurrence}{Sample Size}[/tex]

By Substitution; Probability = [tex]\frac{1}{6}[/tex]

Probability of pulling out a green marble

Given

Red = 12

Green = 10

Yellow = 2

Blue = 19

Purple = 9

Total = 12 + 10 + 2 + 19 + 9 = 42

Probability of picking a green marble is then calculated as;

Probability of choosing d = [tex]\frac{Number of Green}{Total}[/tex]

By Substitution; Probability = [tex]\frac{10}{42}[/tex]

Probability = [tex]\frac{5}{21}[/tex]

the left and right page numbers of an open book are two consecutive integers whose sum is 329. Find these page numbers.

Answers

329-1=328
328/2=164

Answer: page numbers are 164 and 165

Follow below steps:

The student is seeking to find two consecutive integers whose sum is 329. This is a mathematics problem and involves understanding of even and odd numbers as well as basic algebra. Since the numbers are consecutive, we can represent them as n and n + 1. The sum of these numbers given in the problem is 329, so we have the equation n + (n + 1) = 329.

Solving this equation:

Combine like terms: 2n + 1 = 329

Subtract 1 from both sides: 2n = 328

Divide both sides by 2: n = 164

Thus, the two consecutive page numbers of the book are 164 and 165
