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

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)

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)

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.

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.

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

Answer:

1003

Step-by-step explanation:

The number 7,021 divided by 7 is 103.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

Dividend =7021

Divisor =7

Now,

7021/7=103

Therefore, by algebra the answer will be 103.

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°

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.

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

→ 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

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
