Answer:
22.5 packs of printer paper
Step-by-step explanation:
180/40 = 4.5
at a use of 4.5 per day over a period of 35 days, you have used 157.5
180-157.5 = 22.5
The number of packs of printer paper left after 35 days is given by the equation A = 27.5 packs of printing paper
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 number of packs of printer paper left after 35 days be A
Now , the equation will be
The total number of paper packs = 180 packs
The total number of days for the 180 packs of paper = 40 days
So , the number of packs of paper for 1 day = total number of paper packs / total number of days for the 180 packs of paper
Substituting the values in the equation , we get
The number of packs of paper for 1 day = 180 / 40
The number of packs of paper for 1 day = 4.5 paper packs a day
Now , the number of packs of paper for 35 days = 35 x number of packs of paper for 1 day
Substituting the values in the equation , we get
The number of packs of paper for 35 days = 35 x 4.5
The number of packs of paper for 35 days = 157.5 packs of paper
So , the number of packs of printer paper left after 35 days = total number of paper packs - number of packs of paper for 35 days
Substituting the values in the equation , we get
The number of packs of printer paper left after 35 days A = 180 - 157.5
The number of packs of printer paper left after 35 days A = 22.5 packs
Therefore , the value of A is 22.5 packs of paper
Hence , the number of packs of paper remaining is 22.5 packs

What is the equation and one of the solutions to this equation?
A.X2 + (-6.5) = 42.5; 2 = 7
B.X2? + (-6.5) = 42.5; 2 = 6
C.2x+ (-6.5) = 42.5; x = 24.5
D.2x+ (-6.5) = 42.5; I = 18
Answer:
7, -7
Step-by-step explanation:
x^2-6.5= 42.5 add 6.5 to both sides
x^2= 49

Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree? Use an example to explain
Answer:
I do not agree because Mario's claim is not general.
Step-by-step explanation:
Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.
And a denominator is the divisor in a given fraction.
Considering the following fractions whose denominators are prime numbers:
[tex]\frac{2}{3}[/tex] = 0.66666666...
[tex]\frac{1}{7}[/tex] = 0.142857142
[tex]\frac{5}{11}[/tex] = 0.45454545...
[tex]\frac{3}{13}[/tex] = 0.23076923
[tex]\frac{1}{7}[/tex] = 0.142857142
It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.

The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10-4
Answer:
3.5
Step-by-step explanation:
The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4
We have the Logarithmic equation
pH=-log [H3O+],
We have the hydronium ion concentration = 3.2 x 10^-4
Hence,
pH = - log[3.2 × 10 ^-4]
pH = 3.4948500217
Approximately
pH = 3.5
Therefore, the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4 is 3.5
