A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.25 mi long. You walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk?
Your friend walks approximately 0.3925 miles farther than you along the curved path of the pond.
Explanation:To find out how much farther your friend walks, we need to compare the distance along the bridge to the distance halfway around the pond. The bridge is a straight line across the pond, which is the same as the diameter of the pond. The diameter is 0.25 miles long. Your friend walks halfway around the pond, which is equivalent to walking half the circumference of the pond. The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. Since the bridge is the diameter, it is equal to 2 times the radius, or 2r. So the distance your friend walks is half the circumference or (1/2)(2πr) = πr. Since the diameter is 0.25 miles, the radius is half of that, or 0.125 miles. Plugging this into the formula, we find that your friend walks π(0.125) miles. To find a numerical approximation, we can use the fact that π is approximately 3.14, so your friend walks 3.14(0.125) miles. This simplifies to approximately 0.3925 miles. Therefore, your friend walks approximately 0.3925 miles farther than you along the curved path of the pond.

Jess spent 7x minutes on the computer. Her sister spent 5 x + 10 minutes on the computer, which was the same amount of time Jess spent. How many minutes was Jess on the computer?
Answer: 35 minutes
Step-by-step explanation:
Given : Jess spent 7x minutes on the computer.
Her sister spent 5 x + 10 minutes on the computer, which was the same amount of time Jess spent.
Thus , we have
[tex]7x=5x+10[/tex]
Subtract 5x from both the sides , we get
[tex]2x=10[/tex]
Divide both sides by 2, we get
[tex]x=5[/tex]
Now, the time spent by Jess = 7(5)=35 minutes
Hence, Jess was 35 minutes on computer.

What property of addition is shown in the following number sentence? Explain 7+(3+5)=(7+3)+5
The required property is associative property.
Given that,
To determine a property of addition is shown in the following number sentence 7+(3+5)=(7+3)+5.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
7 + (3 + 5) = (7 + 3) + 5
Here, accoding to the PEMDAS rule, in mathematical string solution of the parenthesis is on priority. But we can see here on the left we add first 3 and 5 then the product adds to 7 and on the right, we add first 7 and 3 then the product adds to 5 gives the same result, this property of addition of number is called associative property.
As
7 + (3 + 5) = (7 + 3) + 5
7 + 8 = 10 + 5
15 = 15
Thus, the required property is associative property.

When performing today's experiment, your lab partner decides to add all the reagents into one beaker instead of two separate beakers. after adding everything together and waiting a significant amount of time, you see no reaction occur. what was the problem?
The problem can be an incorrect sequence of reagents added, requirement of heat or proportion of relative reactants when all the reagents simultaneously added into the beaker.
Further explanation:
The reaction sometimes occurs in a series of elementary reaction which can be described in the reaction mechanism of that particular reaction. So when we added the incorrect sequence of reagents then the reaction may not happen as the way we want.
Some factors which can affect the reaction are as follows:
1. The ratio amount of given reagent may not be correct.
2. Some of the reactions have very slow rate of reactions and thus they required heat to increase the rate of reaction.
3. Sometimes the reagent which is important for the first step can undergo a side reaction with the reagent which should not be there otherwise.
4. That mechanism of reaction may be required light since chemoluminescence reactions depend on excitation of atoms.
5. Sometimes reactants should be mix in dark which can lose their activity in the light.

There are 62 rows of 9 chairs about how many chairs are there???
There are 558 chairs in total.
Explanation:To find the total number of chairs, you need to multiply the number of rows by the number of chairs in each row. In this case, there are 62 rows and 9 chairs in each row. So, the total number of chairs would be 62 x 9 = 558.

the sum of two numbers is 7/8. One addend is 3/4. what is the other? A. 4/4 B. 1/8 C. 1/4 D. 2/8
Answer:
Step-by-step explanation:
Let the other be [tex] = x[/tex]
As the sum of the number is given as [tex] \frac {7}{8}[/tex]
And one number is [tex] \frac{3}{4}[/tex]
According to question
[tex] \frac{3}{4} +x = \frac{7}{8}[/tex]
Subtracting [tex] \frac{3}{4}[/tex] from both sides we get
[tex] \frac{3}{4} +x - \frac{3}{4} = \frac{7}{8} - \frac{3}{4}[/tex]
Taking LCM of 4 and 8 we get 8
And making
[tex] \frac{3}{4} [/tex] and [tex]\frac{7}{8}[/tex] like fraction by making denominator same.
Multiply [tex] \frac{3}{4} [/tex] by 2 in numerator and denominator and multiply [tex]\frac {7}{8}[/tex] by 1 in numerator and denominator we get
[tex]x= \frac{7}{8} - \frac{6}{8}[/tex]
[tex]x= \frac{7-6}{8}[/tex]
[tex]x =\frac{1}{8}[/tex]
Hence, the other number is [tex]\frac{1}{8}[/tex]
Harry rides his bike 25 Start Fraction 3 over 8 End Fraction miles. Karen rides her bike 25two-fifths miles. Who rides farther?
Final answer:
After converting their distances to decimals, Karen rides farther than Harry with a distance of 25.4 miles compared to Harry's 25.375 miles.
Explanation:
The question is regarding who rides farther, Harry or Karen, given their distances in different fractional forms. Harry rides his bike 25 3/8 miles, and Karen rides 25 two-fifths miles. To compare, we must convert their distances to similar fractional forms or decimals. Converting three-eighths to a decimal gives us 0.375, and converting two-fifths to a decimal yields 0.4. Therefore, Harry rides 25.375 miles, and Karen rides 25.4 miles.
Through comparison, it is clear that Karen rides farther than Harry. Karen's total distance of 25.4 miles exceeds Harry's total distance of 25.375 miles, albeit by a slight margin.
