If the Percent of Discount is 15% and the Sale Price is $146.54 what the Original Price? PLS Y'ALL GET 100 POINTS FOR DIS! PLS HELP ME!!??

Answers

Answer: the original price of the item was $172.40.

Step-by-step explanation: If the percent of discount is 15% and the sale price is $146.54, we can use the following formula to find the original price:

Original price = Sale price / (1 - Percent discount as a decimal)

First, we need to convert the percent discount to a decimal by dividing it by 100:

15% = 0.15

Substituting the given values into the formula, we get:

Original price = 146.54 / (1 - 0.15)

Original price = 146.54 / 0.85

Original price = $172.40

Therefore, the original price of the item was $172.40.

Answer:

172.40

Step-by-step explanation:

w-[0.15]=146.54

so w-85p=146.54

146.54 divided by 80=1.724 so when you make it a percent it turns it into 172.40 which is the final answer for the money.

Does 6/10+8/100 = 14/10 or 68/10??

Answers

Answer:

The answer is 68/100 or 17/25

Step-by-step explanation:

To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25

At Pruitt’s farm, the ratio of oranges to apples is 4 to 8. A total of 96 apples and oranges are grown on his farm. Find the number of oranges grown.
A. 64
B. 32
C.12
D. 16

Answers

Answer:

32 (B)

Step-by-step explanation:

Because there is a total of 96 apples and oranges, you would divide 96 by 12 because 4 + 8 = 12. 96/12 is 8, so we know that each part (1 part of the ratio) would be 8. Since we are finding the number of oranges, you would multiply 4 x 8 which is 32. (B)

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)

Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)

Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?

Answers

Answer:

Step-by-step explanation:

Part A: A reasonable domain to plot the growth function would be from 0 to a reasonable maximum number of days, such as 30 or 60, depending on the duration of the study.

Part B: The y-intercept of the graph of the function f(d) represents the initial radius of the algae when d = 0, which would be 9 mm.

Part C: To find the average rate of change of the function f(d) from d = 3 to d = 9, we can calculate the difference in the function values at these two points and divide it by the difference in the input values. The average rate of change represents the average growth rate of the algae over that time period.

Answer:

The error made in simplifying the expression is that 54 · 1 is supposed to be equivalent to 54, not 1.

Step-by-step explanation:

The Multiplication Property of One states that any number that is multiplied by one will stay the same, keeping its exact numerical value as before. However, in the expression shown, 54 multiplied 1 ended up equaling 1, which does not fit the Multiplication Property of One. Therefore, the error made in simplifying the expression is that 54 · 1 is supposed to equal 54, and not 1, based on the rule of multiplying any number by 1.

Have a great day! Feel free to let me know if you have any more questions :)

54^1 would be 1, but in this instance we are multiplying 54 by 1 so that means 1 goes into 54, 54 times. This means the answer is 54

What is a variable?

A variable is a symbol used to denote a mathematical object in mathematics. Any number, vector, matrix, function, function argument, set, or set element can be represented by a variable.

An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable is, in other words, a symbol denoting a number whose value is unknown.

You can use A as a different variable by simply assigning a value to it, like any other variable. For example, you could write "A = -6" to assign the value of negative 6 to A. It's important to remember that A is now a distinct variable from X, Y, and K, and should be treated as such in your code or equations.

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each player have?

Answers

Answer:

1,483 is the answer

Answer:

Step-by-step explanation:

Let's say Pedro got x hits

and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the

equation will be as (x+y)=2685................eq (1)

Given,Pedro had 281 more hits than Ricky.So the equation looks like

x=281+y..........eq(2).

substitute eq(2) in eq(1).We get,

2685=(281+y)+y

2685=281+2y

2685-281=2y

2404=2y

2404/2=y

y=1202

substitute y=1202 in eq(2).We get,

x=1202+281

x=1483

So,Pedro hit 1483 and Ricky hit 1202

Answer: 10x = 4 is x = 0.4.

To solve the equation 10x = 4, we want to isolate the variable x on one side of the equation.

First, we divide both sides of the equation by 10:

10x / 10 = 4 / 10

Simplifying:

x = 0.4

Therefore, the solution to the equation 10x = 4 is x = 0.4.

How many of Frankie's apps are educational?
A 5

Answers

Answer: A(5)

Step-by-step explanation: First we need to convert 1/5 to 2/10 so we not work with the fractions. So 2/10 apps were social media and 7/10 were games so we can add those together to get 9/10. So 9/10 apps are not educational. We know 50÷10=5 so 5×9=45 so 45 apps are non-educational so that means 5 apps are educational.

Hope this helps!

1/5 of 50 = 10

7/10 of 50 = 35

1/10 of 50 = 5

there would be space for 5 educational apps <3

The height is the difference from (-4, 4) and (-4, -3), which is 7 units. Thus, the area is (1/2) * 6 * 7 = 21 square units
