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.

how do you find the percentage of exponential decay?
Answer:
When an original amount is reduced by a consistent rate over a period of time, exponential decay is occurring. This example shows how to work a consistent rate problem or calculate the decay factor. The key to understanding the decay factor is learning about percent change.

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

Abby can buy a 7lb. bag of dry cat food for $7.49, or she can purchase a 3lb. bag for $5.40. Which size is the best buy?
Answer:
The 7 pound bag.
Step-by-step explanation:
7.49 divided by 7 is 1.07
5.40 divided by 3 is 1.80
So, the 7 pound bag would be a better deal because 1.07 is less than 1.80.

Kayla squared a number x and added this result to -6.5. This gave her an answer of 42.5.
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
The square root of 49 is 7 and -7.
Which expression shows the perimeter of the triangle in simplest form?
A. 6x + 7
B. 7x + 5
C. 5x + 3
D. 6x + 3
Answer:
D. 6x + 3
Step-by-step explanation:
A perimeter is just the sum of all sides of a shape.
First, write an equation to add all sides of the triangle:
(x + 4) + (3x - 2) + (2x + 1)
What is inside the parentheses is all already simplified. Also, it is addition, so the order in which we add does not matter. So, we can now get rid of the parentheses and combine like terms:
x + 3x + 2x + 4 -2 + 1
6x + 3
And that's our final answer: 6x + 3

Mr. Bon Jovi ordered some pizzas to be delivered. The bill for the pizza was m dollars. Mr. Bon Jovi tipped the pizza delivery driver 15% of the bill.
a. Write an expression for the total amount of money Mr. Bon Jovi paid.
Answer:
t=m(1.15)
Step-by-step explanation:
lets say t=total payment after tip.
m=order price
we know that 15%- .15 so add .15 to 1 to get 1.15 which is what you multiple by m to get the total price, or t

What is the point-slope equation of the line that is perpendicular to the line shown and passes through (-4, -3)?
Answer:
y+3= -4x
Step-by-step explanation:
general equation is (y-y1) = m(x-x1)
m=rise/run= -4/1 (is negative because looking from left to right on the graph it goes downward)
pick any point on the line to put in. the equation for example (0,-3)
y+3= -4x
BRAINLIST ANSWER URGENT! What is wrong with the problem?
A. They should have canceled our factors to simplify at the end
B. They shouldn’t have combined like terms
C. They didn’t get common denominators
D. They needed to cancel out X’s
Answer:
The correct answer would be C they did not get common denominators
Step-by-step explanation:
You can only add fractions with common denominators for example you can not add 1/7 and 1/8 because the denominators are not equivalent.
I hope this helps you!!
