You can use A as a different variable by simply assigning a value to it, like any other 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.

Answer: The Constant of Proportionality is 506.

Step-by-step explanation:

At 1 hour the plane traveled 560 Miles and at the second hour it had traveled 1,120 miles.

560+560=1,120 and if you add 560 to 1,120 you will get 1,680 which is the distance traveled at 3 hours. Therefore the answer is 560.

Answer:

First question's answer: 28y

Second question's answer: c + 12

Step-by-step explanation:

first question explanation:

7(4y) =28y

7 times 4 is 28, simply attach the y on.

Second question explanation

(0 + c) + 12 = c + 12

0 + c simplifies to just c

c + 12 cannot be simplified even more

Answer: The answers are n+8=15, 15-8=n,and 15-n=8

Step-by-step explanation:

The reason why its those three is because if you solve them they equal 7 as the missing number but if you try 15+n=8 it doesnt make any sense.

The expression [tex]3w \cdot (4x \cdot 2y) - 5z[/tex] is equivalent.

Step-by-step explanation:

It doesn't matter what order you multiply things, you will get the same answer even if you ordered it differently. Therefore, [tex]3w \cdot (4x \cdot 2y) - 5z[/tex] is equivalent to [tex](3w \cdot 4x) \cdot 2y - 5z[/tex].

Answer: X=  -4  

Step-by-step explanation:

4x+28= -6x-12 (28-28), (12-28)

4x= -6x - 40

(add 6x to both sides)

4x+ 6x= -6x-40 + 6x

(combine 4x+6x)

10x = -40

(divide 10)

10x/10x

-40/10x

X= -4

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.

Answer: 0.75 or [tex]\frac{3}{4}[/tex]

Step-by-step explanation: Well there are 2 section colored purple, 2 sections yellow, 3 sections are blue, and 1 section is red.

First lets find the number of favorable outcomes, which would be outcomes with out yellow. 6 out of 8 sections do not have yellow therefore the amount of favorable outcomes is 6.

Now for the total amount of outcomes which is 8.

If we input those numbers in this formula [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] so [tex]\frac{6}{8}[/tex] we get 0.75 or [tex]\frac{3}{4}[/tex].

I'm not sure if u were supposed to write smt between pi and 347 but this is the answer I've got

Answer:

The explanation is a little long sorry but I think the answer is B.

Step-by-step explanation:

To find the measure of an angle in the resulting triangle after a translation, we need to understand how translations affect angles.

When a figure is translated, its shape and size remain the same, but its position changes. Translations do not affect the measures of angles in a triangle. Therefore, the measure of an angle in the resulting triangle will be the same as the measure of the corresponding angle in the original triangle.

Since the translation is 6 units to the right and 3 units down, all three vertices of the triangle will move by the same amount. This means that the resulting triangle will have the same shape and size as the original triangle, just shifted to a different position on the coordinate grid.

Therefore, the measure of an angle in the resulting triangle will be the same as the measure of the corresponding angle in the original triangle.

Based on the information given, we cannot determine the measure of an angle in the resulting triangle. The answer options provided (A, B, C, D) do not specify any angles, so we cannot provide a specific measure.

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)

Answer: 2/15 and 9/10

Step-by-step explanation:

Set up cross-multiplication.

If Michelle reads 1/3 book in 2 1/2 hours, she reads X in 1 hour.

                      1/3          2 1/2

                          x           1

1/3 = 2 1/2 x

divide by 2 1/2

1/3 divided by 2 1/2 = convert 2 and a half to 5/2

1/3 divided by 5/2 - keep, change, flip. (your teacher should have covered a method like that)

1/3 times 2/5 is 2/15.

For question 2, lets do the same thing.

3/5 times 2/3 equals x times 1

3/5 times 1 is 3/5

2/3 times x is 2/3x

(this looks better on paper)

3/5=2/3x

divide by 2/3

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.

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

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:

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: 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.

Answer:

21

Step-by-step explanation:

We need to use the formula of area of a triangle to solve this. The formula is (1/2) * base * height. Here, the base is the distance from the line x = -4 to (2, 2), so the base is 6 units. 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

Volume = l x w x h /3 = 12 x 6 x 9 /3 = 216

The volume would be 216
