Answer:
The number of minutes of call for long distance is 500 minutes .
Step-by-step explanation:
Given as :
The two different long distance telephones plans are plan A and Plan B
Plan A
monthly fee = $40.00
The charge per minute = $0.05
Plan B
monthly fee = $15.00
The charge per minute = $0.10
now, for both plans
Let The number of minutes of call for long distance = n minutes
So, According to question
∵ The both plans to be same
Monthly fee for plan A + The charge per minute × number of minutes of call for long distance for A = Monthly fee for plan B + The charge per minute × number of minutes of call for long distance calls for B
i.e $40.00 + $0.05 × n = $15.00 + $0.10 × n
Or, $40.00 - $15.00 = $0.10 × n - $0.05 × n
Or, $25 = $0.05 × n
∴ n = [tex]\dfrac{25}{0.05}[/tex]
I.e n = 500 minutes
So, The number of calls minutes = n = 500 minutes
Hence, The number of minutes of call for long distance is 500 minutes . Answer
What makes a trapezoid an isosceles trapezoid?
Answer:
A: Its legs are congruent
Step-by-step explanation:
A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.
An isosceles trapezoid is a trapezoid with two congruent sides and congruent base angles.
Explanation:An isosceles trapezoid is a trapezoid that has two congruent sides. In other words, the two non-parallel sides of an isosceles trapezoid are equal in length. The base angles of an isosceles trapezoid are also congruent. The parallel sides of an isosceles trapezoid are not equal in length.
For example, if a trapezoid has sides AB = 6 cm, BC = 5 cm, CD = 4 cm, and DA = 5 cm, then it is an isosceles trapezoid because sides BC and DA are congruent.

Which of the following rational numbers represents a repeating decimal 11 / 40 ,3/25, 25/48,or 7/32
[tex]\frac{25}{48}[/tex] represents repeating decimal
Solution:
We are asked to find the rational number that represents repeating decimal
A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely)
Option 1
[tex]\frac{11}{40} = 0.275[/tex]
So here the decimal part is not repeating. So [tex]\frac{11}{40}[/tex] does not represent repeating decimal
Option 2
[tex]\frac{3}{25} =0.12[/tex]
So here the decimal part is not repeating. So [tex]\frac{3}{25}[/tex] does not represent repeating decimal
Option 3
[tex]\frac{25}{48} = 0.52083333333[/tex]
So here in decimal part "3" is repeating and goes on forever
So [tex]\frac{25}{48}[/tex] represents repeating decimal
Option 4
[tex]\frac{7}{32} = 0.21875[/tex]
So here the decimal part is not repeating. So [tex]\frac{7}{32}[/tex] does not represent repeating decimal

Find the other endpoint given one endpoint (-1,6) and the midpoint is (4,2)
Answer:
The required points of the given line segment are ( 9, - 2 ).
Step-by-step explanation:
Given that the line segment AB whose midpoint M is ( 4, 2 ) and point A is ( - 1, 6), then we have to find point B of the line segment AB -
As we know that-
If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and ( [tex]x_{2}, y_{2}[/tex] )then the mid points M are-
M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex] , [tex]\frac{ y_{1} + y_{2}}{2}[/tex] )
Here,
Let A ( - 1, 6 ), B ( x, y ) with midpoint M ( 4, 2 ) -
then by the midpoint formula M are-
( 4, 2 ) = ( [tex]\frac{ - 1 + x}{ 2}[/tex] , [tex]\frac{ 6 + y}{2}[/tex] )
On comparing x coordinate and y coordinate -
We get,
( [tex]\frac{ -1 + x}{2}[/tex] = 4 , [tex]\frac{ 6 + y}{2}[/tex] = 2)
( - 1 + x = 8, 6 + y = 4)
( x = 8 + 1, y = 4 - 6 )
( x = 9, y = -2 )
Hence the required points A are ( 9, - 2 ).
We can also verify by putting these points into Midpoint formula.

B)
3.25x + 2.75y 2 500
2.75x + 3.25y s 500
D)
2.75x + 3.25y 2 500
Answer:
C) 2.75x+3.25y ≤ 500
Step-by-step explanation:
Here are the correct options given:
A) 3.25x +2.75y ≤ 500
B) 3.25x + 2.75y ≥ 500
C) 2.75x + 3.25y ≤ 500
D) 2.75x + 3.25y ≥ 500
Given: Nails cost is $2.75 per pound
Screw cost is $3.25 per pound
Jerry has only $500 to spend on nails and screws.
x represent quantity of nail bought and y represent quantity of screw bought.
As given we know that Jerry has only $500 to spend, so the total cost has to be less than or equal to $500. It cannot go more than $500.
Remember, Total cost= [tex]\textrm{cost of goods per pound}\times quantity[/tex]
Now, Inequality to represent the cost of buying nails and screw.
[tex]\$2.75\times x\ pounds+ \$3.25\times y\ pounds\leq \$ 500[/tex]
∴ [tex]2.75x+3.25y\leq 500[/tex]
There are 30 chairs in the band room mr avery wants to have the same number of chairs in each row there must be more than 1 row and the number of chairs in each row must also be greater than the number of rows explain how mr avery could arrange the chairs
Final answer:
Mr. Avery can arrange the 30 chairs in 5 rows of 6 chairs each or 3 rows of 10 chairs each to satisfy the conditions of having more than one row and the chairs per row being greater than the number of rows.
Explanation:
Mr. Avery can arrange the 30 chairs in the band room in multiple configurations but must satisfy two conditions: there must be more than one row and the number of chairs in each row must be greater than the number of rows. To find such arrangements, we can look for factors of 30 that adhere to these conditions. One possible arrangement is 5 rows with 6 chairs in each row. This satisfies the conditions because there are more than one row, and the number of chairs per row (6) is greater than the number of rows (5).
Another possible arrangement could be 3 rows with 10 chairs each. Here, the condition is also met since there are more than one row and the number of chairs per row (10) is greater than the number of rows (3). Mr. Avery must ensure there's enough space to move around, so he may need to rearrange the chairs to provide adequate pathways between rows.

Good morning,
Answer:
-19
Step-by-step explanation:
(5x−3)/2=3x+8 ⇌ 5x−3 = 2×(3x+8) ⇌ 5x−3 = 6x+16 ⇌ 6x-5x = -3-16
⇌ x=-19.

Answer:
x = - 19
Step-by-step explanation:
Given
[tex]\frac{5x-3}{2}[/tex] = 3x + 8
Multiply both sides by 2 to clear the fraction
5x - 3 = 6x + 16 ( subtract 6x from both sides )
- x - 3 = 16 ( add 3 to both sides )
- x = 19 ( multiply both sides by - 1 )
x = - 19

Final answer:
The solution set graphic is C - Points on negative x-axis.
Explanation:
The correct solution set graphic for this question is C - Points on negative x-axis.
To determine the solution set graphically, you would need to plot all the possible values of the equation or inequality on a coordinate plane. Option A - Infinite set of points on the line would represent a linear equation or inequality with multiple solutions. Option B - Empty set would mean that there are no solutions to the equation or inequality.

10, 30 and 45
A factor of a number is a number by which the given number is evenly divisible.
Example: 2 is a factor of 4 as [tex]4\div 2 =2[/tex]. So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.
Now, factors of 10 = 1, 2, 5, 10.
Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.
Factors of 45 = 1, 3, 5, 9, 15, 45.
So, the greatest common factor in all the three numbers is 5.
Hence, the greatest common factor of 10, 30 and 45 is 5.

The area of a 2D form is the amount of space within its perimeter. The width of the rectangle is 10/7 miles.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of a rectangle is the product of its length and its width, therefore, the width of the rectangle can be written as,
Area = Length × Width
Width = Area / Length
Given the area of the rectangle is 6/7 square miles, while the length of the rectangle is 3/5 miles, therefore, the width of the rectangle is,
Width = (6/7)/(3/5)
Width = (6×5)/(7×3) = 10/7
Hence, the width of the rectangle is 10/7 miles.

Asa saves dimes and quarters so that he will have exact change for he bus. He dabs and then dumps the container that he has been using for collecting his coins and finds he has 47 coins that are worth $9.50. How many of each coin does he have?
Answer:
He have 32 quarters and 15 dimes.
Step-by-step explanation:
Given:
Asa saves dimes and quarters so that he will have exact change for the bus.
He has 47 coins that are worth $9.50.
Now, to find the number of coin each he have.
Let the number of quarters be [tex]x.[/tex]
And the number of dimes be [tex]y.[/tex]
So, the total number of coins are:
[tex]x+y=47.[/tex]
[tex]y=47-x.[/tex].........(1)
As given the total worth of coins = $9.50
And the value of a quarter = $0.25 and the value of a dime = $0.10.
Now, the total worth of coins are:
[tex]0.25x+0.10y=9.50[/tex]
Putting the equation (1) in the place of [tex]y[/tex] we get:
[tex]0.25x+0.10(47-x)=9.50[/tex]
[tex]0.25x+4.7-0.10x=9.50[/tex]
[tex]0.15x+4.7=9.50[/tex]
Subtracting both sides by 4.7 we get:
[tex]0.15x=4.80[/tex]
Dividing both sides by 0.15 we get:
[tex]x=32.[/tex]
The number of quarters = 32.
Now, putting the value of [tex]x[/tex] in equation (1) we get:
[tex]y=47-32.[/tex]
[tex]y=15.[/tex]
The number of dimes = 15.
Therefore, he have 32 quarters and 15 dimes.
