You run 5 miles in 1 hour. At this rate, how long will it take you to run a marathon (approximately 26 miles)?
I got 5 hours and 2 minutes and I'm not sure if I'm correct.
Answer:
5 hours 12 mins
Step-by-step explanation:
You run 5 miles in 1 hour.
5 miles = 1 hour
1 mile = 1 ÷ 5 = 0.2 hour
1 mile = 0.2 hour
26 miles = 0.2 x 26 = 5.2 hours
5.2 hours = 5 hours + (0.2 x 60) mins
5.2 hours = 5 hours 12 mins
If the speed is 5 miles per hour. Then the time taken to complete marathon of 26 miles will be 5 hours and 12 minutes.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
You run 5 miles in 1 hour.
Then the speed will be
Speed = 5/1
Speed = 5 miles per hour
Then the time taken to complete marathon of 26 miles will be
Time = Distance / Speed
Time = 26 / 5
Time = 5.2 hours
The time 5.2 hours can be written as 5 hours and 12 minutes.

The total area of two rectangles can be represented by the expression (x)(3x+1) + (2x)(x+3). Which expression represents the total area of the two rectangles?
Answer:
The total area of the two rectangles is [tex](5x^{2} +7x)\ units^{2}[/tex]
Step-by-step explanation:
Area of rectangle 1
[tex](x)(3x+1)=(3x^{2} +x)\ units^{2}[/tex]
Area of rectangle 2
[tex](2x)(x+3)=(2x^{2} +6x)\ units^{2}[/tex]
therefore
The total area of the two rectangles is equal to
[tex](3x^{2} +x)\ units^{2}+(2x^{2} +6x)\ units^{2}=(5x^{2} +7x)\ units^{2}[/tex]
The correct choice is [tex]5x^{2} +7x[/tex]. By expanding and combining the terms, the total area of the two rectangles is represented by the expression found.
Let's first expand each term in the expression (x)(3x+1) + (2x)(x+3) to determine the total area of the two rectangles:
(x)(3x+1) = [tex]3x^{2} +x[/tex](2x)(x+3) = [tex]2x^{2} +6x[/tex]Now, add the two results together:
[tex]3x^{2}[/tex] + x + [tex]2x^{2}[/tex] + 6x = [tex]5x^{2} +7x[/tex]Therefore, the expression that represents the total area of the two rectangles is [tex]5x^{2} +7x\\[/tex] .

What size picture will result when a 5 in. • 7 in. Picture is reduced using an 80% setting?
A 5" * 7" image reduced by 20% in scale to 80% of the original size will be 4" * 5.6". Roughly the size of a large flash card.
When a 5 inch by 7 inch picture is reduced using an 80% setting, the new dimensions will be 4 inches by 5.6 inches.
To calculate the new size of a 5 inch by 7 inch picture when reduced by 80%, we simply multiply both dimensions by the reduction percentage. Hence, the width and the height of the picture will be reduced to 80% of their original size.
Original width: 5 inches
Original height: 7 inches
Reduction setting: 80% (or 0.8)
New width: 5 inches × 0.8 = 4 inches
New height: 7 inches × 0.8 = 5.6 inches
Therefore, the new dimensions of the picture will be 4 inches by 5.6 inches after an 80% reduction.

is paid an annual salary of $26,000. Find the Pat's weekly salary
Answer:500
Step-by-step explanation:26,000/52=500 i did $26,000 divided by 52 because there are 52 weeks in a year and it gave me 500 so that is how i got the answer
There are 52 weeks in a year, so the annual salary is 52 times the week salary.
So, we have
[tex]\dfrac{26000}{52} = 500[/tex]

In an examination, 15% candidates failed in science and 20% in Mathematics. If 10% failed in both the subjects, find percentage of those who passed in both the subjects.
To determine the percentage of students who passed both exams, we first calculate the percentage of students who failed in either subject, then subtract that from 100%. Given that 15% failed in Science, 20% in Mathematics, and that 10% failed in both, we find that 75% of students passed both courses.
Explanation:In this question, we have to find out the percentage of the candidates that passed in both subjects, Science and Mathematics. The percentages given show the failure rates in Science, Mathematics, and in both. Here, we need to use the concept of sets where we sum the individual percentages and subtract the intersection. It is defined as P(A U B) = P(A) + P(B) - P(A ∩ B).
According to the problem, 15% failed in Science and 20% in Mathematics. So, the candidates failing in any one of the subjects would be 15% + 20% = 35%. However, those who failed in both subjects (i.e., intersection part) is 10%, and double-counted when we added up the individual percentages. Therefore, we subtract this from our earlier total, giving us 35% - 10% = 25%. This implies that 25% of candidates fail in at least one subject.
As for those who pass in both, since we know that the total should be 100%, and we've figured out that 25% failed in at least one subject, thus, those who passed should be the remaining 75%.

The percentage of those who passed in both the subjects is equal to 85%.
How to determine the percentage of those who passed in both the subjects?In order to determine the percentage of those who passed in both the subjects, we can use the principle of inclusion and exclusion;
Let the variable A represent the percentage of candidates who failed in Science, which is 15%.Let the variable B represent the percentage of candidates who failed in Mathematics, which is 20%.Let the variable C represent the percentage of candidates who failed in both Science and Mathematics, which is 10%.Let the variable P represent the percentage of candidates who passed in both Science and Mathematics.Based on the principle of inclusion and exclusion, we have:
Total percentage of candidates who failed in either Science or Mathematics = A + B - C
Percentage of candidates who passed in both subjects = 100% - (A + B - C)
Percentage of candidates who passed in both subjects = 100% - (15% + 20% - 10%)
Percentage of candidates who passed in both subjects = 100% - 15%
Percentage of candidates who passed in both subjects = 85%.

find the LCM of m^2 - 4m - 5 and m^2 + 8m + 7
Answer:
LCM=(m+1)(m-5)(m+7)
Step-by-step explanation:
Given expressions are [tex]m^2-4m-5[/tex] and [tex]m^2+8m+7[/tex].
To find the LCM, first we need to find factors of both expressions.
[tex]m^2-4m-5[/tex]
[tex]=m^2+1m-5m-5[/tex]
[tex]=m(m+1)-5(m+1)[/tex]
[tex]=(m+1)(m-5)[/tex]
Similarly factor other expression
[tex]m^2+8m+7[/tex]
[tex]=(m+1)(m+7)[/tex]
Common factor in both is (m+1)
bring down remaining non-common factors.
So LCM=(m+1)(m-5)(m+7)

Find the solution of this system of equations. 3x+7y=46 -3x-8y=50
The solution to the system of equations 3x + 7y = 46 and -3x - 8y = 50 is x = 239.333... and y = -96. This can be verified by plugging these values back into the original equations.
Explanation:To find the solution of this system of equations, we can use the method of adding the two equations together, as they are set up nicely for elimination:
3x + 7y = 46-3x - 8y = 50Add the two equations together:
3x + 7y - 3x - 8y = 46 + 50
0x - y = 96
y = -96
Substitute y = -96 back into one of the original equations, for example the first equation:
3x + 7(-96) = 46
3x - 672 = 46
3x = 46 + 672
3x = 718
x = 718 / 3
x = 239.333...
The solution to the system is x = 239.333... and y = -96. We can verify the solutions by substituting back into the original equations.

A recipe calls for 2/3 cup of flour for every 4 teaspoons of vanilla. How much vanilla should be used for every 1 cups of flour?
A. 1/6
B. 2 2/3
C. 4 2/3
D. 6
Please help and explain everything! Thanks!
Answer: For 1 cup of flour, there should be 6 teaspoons of vanilla.
Step-by-step explanation:
What I did is that I found what 1 ÷ 2/3 equals. To find that, I used the reciprocal so the new equation would be 1 × 3/2 which equals 3/2. So since 2/3 × 3/2 equals 1, we have to do the same to 4 teaspoons. 4 × 3/2 equals 6. Therefore, there should be 6 teaspoons of vanilla for every one cup of flour.
Hope this helps! Don't hesitate to ask for clarification.

Solve the inequality -x/2 ≤ 1. Let's eliminate the fraction first, by multiplying both sides by 2:
-x ≤ 2
We want to solve for +x, not for -x.
Therefore, divide both sides of this latest inequality by -1, remembering to reverse the direction of the inequality sign:
-x ≤ 2 → x ≥ -2
