The number of hours when he has to walk 6 miles will be 2 hours.
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
If you walk three miles per hour to school. The number of hours when he has to walk 6 miles will be given as,
3 = 6 / T
Simplify the equation, then we have
3 = 6 / T
T = 6 / 3
T = 2 hours
The number of hours when he has to walk 6 miles will be 2 hours.

A magazine provided results from a poll of 20002000 adults who were asked to identify their favorite pie. Among the 20002000 respondents, 1414% chose chocolate pie, and the margin of error was given as plus or minus±33 percentage points. What values do ModifyingAbove p with caretp, ModifyingAbove q with caretq, n, E, and p represent? If the confidence level is 9999%, what is the value of alphaα?
Answer:
Step-by-step explanation:
Given that:
The sample size n = 2000
The sample proportion [tex]\hat p[/tex] = 0.14
If [tex]\hat p[/tex] = 0.14, then [tex]\hat q[/tex] = 1 - [tex]\hat p[/tex]
[tex]\hat q[/tex] = 1 - 0.14
[tex]\hat q[/tex] = 0.86
The margin of error = 0.03
Given that the confidence interval level = 99%
The significance level is the value of alpha ∝ = 1 - 0.99
∝ = 0.01
the volume of the box is ___
Answer:
[tex]V=80x-36x^2+4x^3[/tex]
Step-by-step explanation:
The volume of a box of dimensions a, b, c is:
V=abc
The box shown in the image has dimensions 8-2x, 10-2x, x, thus its volume is:
[tex]V=(8-2x)(10-2x)(x)[/tex]
Operating the first two brackets:
[tex]V=(80-16x-20x+4x^2)(x)[/tex]
Joining like terms:
[tex]V=(80-36x+4x^2)(x)[/tex]
Multiplying again:
[tex]V=80x-36x^2+4x^3[/tex]
The volume of the box is
[tex]\boxed{V=80x-36x^2+4x^3}[/tex]

point M with coordinates (3,4) is the midpoint of the line AB and A has the point (-1,6). what is the point of B?
Answer:
B = (7, 2)
Step-by-step explanation:
B = 2M -A
B = 2(3, 4) -(-1, 6) = (2·3-(-1), 2·4-6)
B = (7, 2)
_____
The expression for the other end point, B, comes from the equation for the midpoint.
M = (A +B)/2
2M = A + B . . . . . multiply by 2
2M -A = B . . . . . . subtract A to get an expression for B
Renting a tent from the party supply store costs $100 for the insurance fee and $50 for each hour rented. Write an algebraic expression to represent this situation based on the number of hours the tent was rented. What is the coefficient in the expression
Answer:
100 + 50h
Step-by-step explanation:
Given
Represent the hour with h.
Insurance Fee = $100
Hours = h
Cost per hour = 50
Required
Determine an algebraic expression
The expression is as follows:
Expression = Insurance Fee + Cost per hour * number of hours
Expression = 100 + 50 * h
Expression = 100 + 50h
The coefficient in the question is the number of hours (h)

3(3x-8)-5(3x-8)=(4x-16)-6(x-2)
Answer:
the answer should be 5
Step-by-step explanation:
Remove parentheses.
3(3x-8)-5(3x-8)=4x-16-6(x-2)3(3x−8)−5(3x−8)=4x−16−6(x−2)
2 Simplify 3(3x-8)-5(3x-8)3(3x−8)−5(3x−8) to -2(3x-8)−2(3x−8).
-2(3x-8)=4x-16-6(x-2)−2(3x−8)=4x−16−6(x−2)
3 Expand.
-6x+16=4x-16-6x+12−6x+16=4x−16−6x+12
4 Simplify 4x-16-6x+124x−16−6x+12 to -2x-4−2x−4.
-6x+16=-2x-4−6x+16=−2x−4
5 Add 6x6x to both sides.
16=-2x-4+6x16=−2x−4+6x
6 Simplify -2x-4+6x−2x−4+6x to 4x-44x−4.
16=4x-416=4x−4
7 Add 44 to both sides.
16+4=4x16+4=4x

Cindy, who is self-employed, maintains an office in her home that comprises 16% (260 square feet) of total floor space. Gross income for her business is $44,150, and her residence expenses are as follows: Real property taxes $4,188 Interest on mortgage 6,980 Operating expenses 3,490 Depreciation (based on 16% business use) 3,755 If required, round your final answer to the nearest dollar. a. What is Cindy's office in the home deduction based on the regular method? $ b. What is Cindy's office in the home deduction based on the simplified method? $
Deduction :
Real property taxes = 16% * $4,188 = $670.08
Interest on mortgage = 16% * 6,980 = $1116.80
Operating expenses = 16% * 3,490 = $558.40
Depreciation (based on 16% business use) = 3,755
Total deduction:
$(670. 08 + 1116.80 + 5558.40 + 3755) = $11,100.28
Simplified deduction :
$5 per square foot of home used for business
Number of square feet = 260
$5 * 260 = $1300
For a special movie premiere, the theater owner decided to charge $20 per ticket for the first r rows of the theater and $15 for the remaining rows. 2. Explain how you could find the owner's total income if you knew the value of r and you knew that all tickets were sold. 3. Suppose r=16. A. Find the income in the first r rows if all of the tickets were sold. B. Find the income in the remaining r rows if all of the tickets were sold. C. Find the total income for r=16. 4. Write and simplify an expression for the owner's profit if tickets are priced at $20 per ticket in the first r rows and $15 per ticket in the remaining rows, if all seats are sold. 5. Evaluate the expression you wrote in Question 4 for r=16 and show that the result equals your answer in Question 3c.
Answer & Step-by-step explanation:
2. Total income = Income from first r rows + Income from other last rows
[(Price per first r rows' seat ) x (no of first r rows) x (no of seats per first r row) ] + [ (Price per other last rows' seat ) x (no of last rows) x (no of seats per last row) ]
= [ 20 x (r) x (no of seats per first r row) ] + [ 15 x (other last ie 'total - r' rows) x no of seats per last row
3. 20 x 16 x (no of seats per first r row) = 320 x (no of seats per first r row)
4. 15 x (other last ie 'total - 16' rows) x no of seats per last row

The answer for number 3 is y=2x+b.
For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).
-5=2(-4)+b Now simplify
-5=-8+b then add 8 to both sides to isolate b
3=b or b=3
For number 9, you now know that m is 2 and b is 3
y=2x+3
