What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the equation is
Let the amount for renting the machine be = $ 70
The amount per bag for packing popcorn = $ 0.15 per bag
The sale price of the popcorn per bag = $ 1.00
And ,
The total number of bags sold by Rodney = 200 bags
So , the total profit made by Rodney A is calculated from the equation ,
Total amount made by Rodney = total number of bags sold by Rodney x sale price of the popcorn per bag
Substituting the values in the equation , we get
Total amount made by Rodney = 200 x 1
Total amount made by Rodney = $ 200
Now , the cost per bag is deducted from the total amount made by Rodney
So ,
Total amount made by Rodney after deduction of bag cost = ( Total amount made by Rodney - amount per bag for packing popcorn x 200 )
Substituting the values in the equation , we get
Total amount made by Rodney after deduction of bag cost =
= 200 - ( 0.15 x 200 )
= 200 - 30
= $ 170
Now , the cost of renting the machine should also be deducted from the remaining amount to calculate the profit earned by Rodney
So , The profit earned by Rodney A = 170 - amount for renting the machine
The profit earned by Rodney A = $ 170 - $ 70
The profit earned by Rodney A = $ 100
Therefore , the value of A is $ 100
Hence , The amount of profit Rodney made when he sold 200 bags of popcorn is given by A = $ 100

Answer:
d=√73=8.544
Step-by-step explanation:
Find distance (d) between market (0,8) , court house(6,5) and library(6,-1)
d between two pint is :
d=√(x2-x1)²-(y2-y1)²
d between market and court house:
d=√(6-0)²+(5-8)²
d=√36+9=√45 = 6.7082 ≅6.71 rounded to the nearest hundredths
d between courthouse and the library:
d=√(6-6)²+(-1-5)²
d=√36=6
the distance that Runner A ran=6.71+6=12.71
the distance from the library to the school:
d=√(6-(-2))²+(-1-(-4))²
d=√8²+3²
d=√64+9
d=√73=8.544 ( rounded to the nearest hundredth)
Runner B went 8.544 further than Runner A before stopping at school ( which is the distance between the library and the school.

A third car seat is designed for a child between 25 lb and 75 lb, inclusive. Model those ranges with compound inequalities. Which car seats are appropriate for a 33-lb child? The inequality for a child up to and including 26 lb is ________.
Answer:
the 25 -75 because the baby is closer to 25 but still has plenty of room
The car seat appropriate for a child 33-lb will be shown by the inequality 25 < Child seat < 75. The inequality for a child up to and including 26 lb will be written as Child ≤ 26.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Scratchwork:
tan (50) = tan (40 + 10)
[tex]= \dfrac{\tan 40+\tan 10}{1-\tan 40\cdot \tan 10}[/tex]
tan 50 (1 - tan 40 · tan 10) = tan 40 + tan 10
tan 50 - tan 50 · tan 40 · tan 10 = tan 40 + tan 10
tan 50 = tan 40 + tan 10 + tan 50 · tan 40 · tan 10
Use the Reciprocal Identity: cot A = 1/ tan --> cot A · tan A = 1
Proof LHS → RHS
LHS: tan 50 - tan 40
Substitute tan 50: tan 40 + tan 10 + (tan 50 · tan 40) · tan 10 - tan 40

Given 2^m + 2^m = 2^n, express m in terms of n.
Answer:
m = n-1
Step-by-step explanation:
2^m + 2^m = 2^n
Add on the left
2( 2^m) = 2 ^ n
2^1 ( 2^m) = 2^n
We know that a^b* a^c = a^ (b+c)
2^(1+m) = 2^n
The bases are the same so the exponents are the same
1+m = n
Solving for m
1+m-1 = n-1
m = n-1
Given :
2^m + 2^m = 2ⁿ
→ 2(2^m) = 2ⁿ
→ 2¹ × 2^m = 2ⁿ
→ 2^(1 + m) = 2ⁿ
As bases are equal, exponents are equal too.
→ 1 + m = n
→ m = n - 1
→ m = n - 1 (Answer)8 times 10 to the power of 5 is how many as great as 8 times 10 to the power of -1

the midpoint of ab is M (-6,1 ). if the coordinates of A are (-7,-3 ),what are the coordinates of B
Answer:
B(-5,5).
Step-by-step explanation:
It is given that midpoint of AB is M (-6,1).
Coordinates of A are (-7,-3 ).
We need to find the coordinates of point B.
Let coordinates of point B are (a,b).
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Midpoint of AB is
[tex]Midpoint=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)[/tex]
[tex](-6,1)=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{-7+a}{2}=-6[/tex]
[tex]-7+a=-12[/tex]
[tex]a=-12+7[/tex]
[tex]a=-5[/tex]
[tex]\dfrac{-3+b}{2}=1[/tex]
[tex]-3+b=2[/tex]
[tex]b=2+3[/tex]
[tex]b=5[/tex]
Therefore, the coordinates of B are (-5,5).
8 times of the eight term of an arithmetic progression is equal to 12 times of the twelfth term. find its first term if the common difference is -2 .
Answer:
a₁ = 38
Step-by-step explanation:
Given AP, where:
8a₈ = 12a₁₂d = -2,a₁ = ?=============
Solutionaₙ = a₁ + (n-1)d
a₈ = a₁ + 7d = a₁ + 7*(-2) = a₁ - 14a₁₂ = a₁ + 11d = a₁ + 11*(-2) = a₁ - 228a₈ = 12a₁₂
8(a₁ - 14) = 12(a₁ - 22)2(a₁ - 14) = 3(a₁ - 22)2a₁ - 28 = 3a₁ - 663a₁ - 2a₁ = -28 + 66a₁ = 38The width of a rectangle measures (3.1s-1.6)(3.1s−1.6) centimeters, and its length measures (7.2s-4.6)(7.2s−4.6) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle? A. −6.2+10.3s B. −12.4+20.6s C. 1.5s+2.6 D. 5.2+3s
Answer:
B) -12.4 + 20.6s
Step-by-step explanation:
width = (3.1s - 1.6) cm
Length = (7.2s - 4.6) cm
Perimeter of rectangle = 2* (length +width)
= 2 *(7.2s - 4.6 + 3.1s - 1.6) {add like terms}
= 2* (7.2s + 3.1s - 4.6 - 1.6)
= 2*( 10.3s - 6.2) {distributive property}
= 2*10.3s - 2*6.2
= 20.6s - 12.4

How many $10$-digit numbers are there, such that the sum of the digits is divisible by $2$?
Complete question is;
How many 10 - digit numbers are there, such that the sum of the digits is divisible by 2?
Answer:
There are 4500000000 ten digit numbers whose sum is divisible by 2.
Step-by-step explanation:
Since we are dealing with 10 digit numbers, the first 10 digit number whose sum is divisible by 2 is; 1000000001.
While the last 10 digit number whose sum is divisible by 2 is 9999999999.
Now,to find how many 10 digit numbers whose sum are divisible by 2, we will simply divide the difference of both numbers by 2 and then add 1 to the answer. This is because subtracting the minimum from the maximum gives us the number of 10 digit numbers we have. Then dividing by 2 gives the number of ten digit numbers with sum divisible by 2 in between. Then adding 1 to the result to cover the number not included gives;
((9999999999 - 1000000001)/2) + 1 = 4500000000
