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: 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:

Table C.

Step-by-step explanation:

------>  x = -2, y = -4 --->k = -4 / -2 = 2

------>  x = -1, y = -2 --->k = -2 / - 1 =2

------>  x = 1, y = 2 --->k = 2/1 = 2

------>  x = 2, y = 4 --->k = 4/2 = 2

Table C, has the same value of k

Thus, table c represent a " proportional relationship "

Answer:

Step-by-step explanation:

Velocity is change in displacement over change in time.

v = d/t

In this problem, d = 1.6 km and t = 20 minutes

To find the velocity, divide 1.6 by 20, and you get 0.08 km/min.

You could also convert this to km/hour by dividing 1.6 km by 1/3 hours, and the velocity would be 4.8 km/hour.

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

Answer:

A. 1 to 12

Step-by-step explanation:

if each business has 4 executives there is a total of 120 executives

30(4) = 120

to find the proportion of executives to offices we divide the number of offices by the number of executives

1440/120 = 12

a more in depth look is

1440 offices / 120 executives

"offices" and "executives" cannot divide each other out, but the 1440 and 120 can so it would be

12 offices / 1 executive

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

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:

Where is the question

Step-by-step explanation:

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:

22

Step-by-step explanation:

Area of rectangle: 6

Area of triangle: 4+3+1 = 8

8x7=56/2 =28

28-6=22

Answer: 22

Step-by-step explanation:

First, you want to find the area of the triangle with the formula 1/2 × b × h.

1/2 x 8 x 7 = 28

Next, you want to find the area of the smaller rectangle with the formula, b x h

3 x 2 = 6

Then, you subtract the two numbers

28 - 6 = 22

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].

the answer is $3.25, look at the picture below:)

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:

258 ft

Step-by-step explanation:

seperate the polygon into two boxes that way u have one big box that is 21 ft in width and 8 ft in height. Then multiply 21*8 to find the area of the box which is 168.

for the other box you can find the height by subtracting 18 ft and 8 ft from the first box which gives a height of 10 ft. To find the wisth you have to subtract 21-12 which is 9. Now you can multiply 10*9=90

Add the two boxes together:

90+168=258

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.
