Step-by-step explanation:
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
Logan and Nathan are shelving books at a public library. Logan shelves 5 books at a time, whereas Nathan shelves 6 books at a time. If they end up shelving the same number of books, what is the smallest number of books each could have shelved?
Answer:
30
Step-by-step explanation:
Given that
Logan shelves 5 books and
Nathan shelves 6 books
They end shelving the same number of books.
To find:
Smallest number of books each could have shelved?
Solution:
First of all, let us have a look at the definition of Least Common Multiple(LCM) of two numbers.
Least Common Multiple (LCM) of two numbers is the minimum number which is divisible by both the numbers.
Now, looking at the statement of the given question.
We have to find the LCM of both the numbers actually.
Making factors of the numbers:
[tex]5=5\times 1[/tex]
[tex]6=2\times 3[/tex]
Nothing is common here, therefore the LCM is [tex]5\times 6 =\bold{30}[/tex].
Smallest number of books shelved = 30
find the perimeter & area of the rectangle
Answer:
Perimeter = [tex]34\sqrt{2}[/tex] feet
Area = 60 feet²
Step-by-step explanation:
Let us revise the rules of perimeter and area of a rectangle
Perimeter = 2(Length + width)Area = Length × Width→ From the given figure
∵ The length = [tex]\sqrt{8}[/tex] feet
∵ The width = 5[tex]\sqrt{18}[/tex] feet
→ Simplify the roots
∵ [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]
∴ [tex]\sqrt{8}=2\sqrt{2}[/tex]
∴ The length = [tex]2\sqrt{2}[/tex] feet
∵ [tex]5\sqrt{18}=5\sqrt{(3)(3)(2)}[/tex]
∴ [tex]5\sqrt{18}=5(3)\sqrt{2}=15\sqrt{2}[/tex]
∴ The width = [tex]15\sqrt{2}[/tex] feet
→ Perimeter = 2(Length + width)
∵ Perimeter = [tex]2[2\sqrt{2}+15\sqrt{2}][/tex]
∴ Perimeter = [tex]2[17\sqrt{2}][/tex]
∴ Perimeter = [tex]34\sqrt{2}[/tex] feet
→ Area = Length × Width
∵ Area = [tex]2\sqrt{2}[/tex] × [tex]15\sqrt{2}[/tex]
∴ Area = [tex](2)(15)(\sqrt{2})(\sqrt{2})=(30)(2)=60[/tex]
∴ Area = 60 feet²

Given the points (20,8) and (10,15) find the slope of the line that goes through them.
Answer:
-7/10
Step-by-step explanation:
You can find the slope by using this formula: [tex]\frac{y-y}{x-x} \\[/tex] (rise over run!)
If you plug in the numbers, it looks like this: [tex]\frac{8-15}{20-10} \\[/tex]
Which simplifies to [tex]-\frac{7}{10}[/tex]

It is really easy to get an answer if you use a graph.
1. take y=2x+1
2. take the slope of it
3. add it to your new equation
4. so y=2x
5. make sure that you check that this intersects the other 2 and your good.
Can someone please help me with these questions?
Answer:
1) 57°
2) 142°
3) 92°
4) 125°
5) 111°
6) 90°
Step-by-step explanation:
Assuming the 2 lines that look parallel in all of these problems, are actually parallel...
m<1 = 57° They are the same angle
m<HJK = 142° (again, same angle)
m<ABC = (4x = 3x + 23) solve for x
x = 23, then substitute 23 for x
4(23) = 92°
m<MPQ = (3x + 50 = 5x). solve for x
x = 25, then substitute 25 for x
3(25) + 50 = 125°
m<3 = 111° They are the same angle
m<4 = 90° If one angle is 90° where the lines cross, all of the angles are 90°
Solve for x: 2 over 3 (x − 4) = 2x
Every day, Ann goes to the gym for 30 minutes and Max goes for 3 times longer. For how long does Max go to the gym every day?
To find this answer, it says that Max goes to the gym 3x longer than Ann. Ann only goes to the gym for 30 minutes.
Multiply the time that Ann goes by 3 to find the time that Max goes.
30 x 3 = 90
Which means, that Max spends 90 minutes at the gym. /
(To simplify, he goes to the gym for 1 hour and 30 minutes)
If you walk to school at a rate of 3 miles per hour how long will it take you to walk 6 miles
Answer:2 hours
Step-by-step explanation:3×2=6 sorry if its wrong
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.
More about the speed link is given below.

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)

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 angles of a quadrilateral are in the ratio 1:2:3:4. Find the measure of each angle
Step-by-step explanation:
Since, the angles of the quadrilateral are in the ratio 1:2:3:4
Therefore, let their measures be x, 2x, 3x and 4x
By angle sum property of the interior angles of a quadrilateral.

Carla traveled 320 miles in 5 hours. At this rate, how far will Carla travel in 7 hours?
Answer:
448 miles
Step-by-step explanation:
If 5 hours = 320 miles
then 7 hours = ?
7 hours will give more so if more less divide
7hours ÷5hours × 320 miles
hours will cancel out
= 7÷5×320 miles
= 448 miles
Hence,Carla will travel 448 miles in 7 hours

What is 127 to the nearest whole number
Answer: 127 to the nearest whole number is 130
Step-by-step explanation:
Since 7 is more than 5, we add 1 to the tenth place (2) which becomes 3 and add that to the original number (7) which gets you 10. After that you add 120 to 10 which gets you 130, therefore, the nearest whole number is 127.
