G: u=-4( t + 3)

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.

Question 14 Explanation:

This question is asking for the total number of books sold on both days.

First Day:

Second Day:

To find the total number of books sold on both days, you add all of these values up:

It doesn't matter in what order you express this thanks to the Communatitive Property of Addition explained below.

Question 15 Explanation:

The Communatitive Property of Addition states that the order of addends do not change the sum. In other words, you can put the addends in any order you want and still get the same sum. You can express 20 + x + y in any order to answer this question (e.g. 20 + y + x, y + x + 20, etc)

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: 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:

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

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:

See below

Step-by-step explanation:

We can see that the thick line which outlines the main cable, the base and tower form a triangle

The longest length is the main cable which is 15m

If it is indeed a right triangle. the squares of the sums of the two shorter sides must equal the square of the longer side.

Sum of squares of shorter sides(also called legs) = 9² + 12²

= 81 + 144

= 225

Square of the longer side = 15² = 225

Since 15² = 9² + 12²

the triangle shown is indeed a right triangle with hypotenuse = 15m and the legs of the right triangle  9m and 12m

Answer:

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].

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: 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.

Answer:

First Question's Answer = 7 + A

Second Question's Answer = (2 x 5) x 7

Step-by-step explanation:

The commutative property of addition states that numbers can be added together in any order without changing the resulting sum.

Therefore, A + 7 = 7 + A

The associative property of multiplication states the way in which three or more terms are grouped does not change the product.

therefore, 2 x (5 x 7) = (2 x 5) x 7

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 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:

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.

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:

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.
