In a recent year, U.S. advertisers spent $60 billion on television advertising. This number made up 40 percent of total advertising. What was the dollar amount spent by U.S. advertisers on all other forms of advertising?
Answer:
The amount spent on all other types of advertising is $90 billion
Step-by-step explanation:
In this question, we are asked to calculate the amount spent on all other forms of advertising given the amount spent on tv advertising and the percentage of the total that it represents.
Firstly, we need to calculate the total amount spent on advertising.
we do not know this amount, so we can call it x.
Now, mathematically;
40% of x = $60 billion
40/100 * x = 60 billion
40x = 100 * 60 billion
x = (100 * 60)/40 = 6000/40 = 150 billion
The amount spent on all other advertising = Total amount spent on advertising- amount spent on television advertising = 150 billion - 60 billion = 90 billion

What is the volume of this piece of wood?
The volume of the wood is found using the formula for the volume of a rectangular prism, which is the product of its length, width, and height. Using the given dimensions, the wood's volume is 9 cubic inches. Density calculations would further require the wood's mass.
Explanation:To find the volume of a piece of wood, you can apply the formula for the volume of a rectangular prism, which is length × width × height. For example, if a piece of wood has dimensions of 6 inches in length, 3 inches in width, and 0.5 inches in height, the calculation for its volume would be:
Volume of the wood = 6 in. × 3 in. × 0.5 in. = 9 in.³.
If we wish to discuss the density of wood, we would need its mass along with its volume. The density can then be calculated by dividing the mass by the volume. Knowing the density is useful as it can help determine if the wood will sink or float when placed in water, an example of the principle of buoyancy.

Wynn needs to find the center of the data set shown on the dot plot. The dot plot has _____ dots. The dot plot has ______dots to the left of the center and dots to the right of the center. The center of the data set is ______________
Answer:
Wynn needs to find the center of the data set shown on the dot plot. The dot plot has ___15__ dots. The dot plot has ___7___dots to the left of the center and dots to the right of the center. The center of the data set is _______8_______
We have assumed that the dot plot has 15 dots for the purpose of solving this case.
Step-by-step explanation:
The center of the dot plot is obtained by subtracting 1 from the total dots and dividing the result by 2.
The center of data is a single number that summarizes the entire data set. It is called the Median. The median represents the midpoint value of a data set, where the values are arranged in ascending or descending order. Unlike the mean, the median can be used to find the center of data when the numbers in the data set contain one or more outliers.
It is one of the measures of central tendencies and the most accurate measure for that matter.
Wynn needs to find the center of the data set shown on the dot plot. The dot plot has 10 dots. The dot plot has 5 dots to the left of the center and dots to the right of the center. The center of the data set is 5.5.
To provide an accurate and complete response, I'll need to define a hypothetical dot plot. Let's assume we have a dot plot representing the following data set:
Now, let's break down the problem:
Number of dots on the dot plot:
- Count the total number of dots: [tex]\(1 + 1 + 1 + 2 + 1 + 1 + 2 + 1 = 10\)[/tex]
- So, the dot plot has 10 dots.
Finding the center of the data set:
- The center of the data set is determined by the median when the data is ordered. Since there are 10 data points (an even number), the median will be the average of the 5th and 6th values when sorted.
Sorted data: [tex]\(2, 3, 4, 5, 5, 6, 7, 8, 8, 9\)[/tex]
The 5th value is 5, and the 6th value is 6. Therefore, the median is:
[tex]\[ \text{Median} = \frac{5 + 6}{2} = 5.5 \][/tex]
Number of dots to the left and right of the center:
- Dots to the left of the median (5.5): [tex]\(2, 3, 4, 5, 5\)[/tex] (5 dots)
- Dots to the right of the median (5.5): [tex]\(6, 7, 8, 8, 9\)[/tex] (5 dots)
- The dot plot has 10 dots.
- The dot plot has 5 dots to the left of the center and 5 dots to the right of the center.
- The center of the data set is 5.5.
Program the VR Robot to drive forward 6 grid squares, turn around, and drive back 6 grid squares. How many degrees did you have to turn to face the way you came? What is the total distance traveled? Use a calculator and/or pencil and paper to find out.
Final answer:
The VR Robot will need to turn 180 degrees to face the original direction after driving forward 6 grid squares. It then drives back the same distance, totaling 12 grid squares or units of distance traveled.
Explanation:
To program a VR Robot to drive forward 6 grid squares, turn around, and drive back 6 grid squares, we need to calculate the total degrees turned and the total distance traveled. When turning to face the way it originally came from, the robot will need to turn 180 degrees.
This is because a half-circle, or a complete about-face turn, is 180 degrees. For the total distance traveled, if each grid square is a standardized distance (let's assume 1 unit distance per grid square), then driving forward 6 grid squares and back would accumulate a total of 12 grid squares or units.
The total distance traveled by the VR robot is 12 units. Turning around to face the original direction is simply a 180-degree turn, whether this is done to the left or to the right.

Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for a total of $6.75, and 4 pieces of crab for $8.00. Which list shows the unit cost of each pieces of sushi from least to greatest? squid, crab, tuna, eel eel, squid, tuna, crab squid, eel, crab, tuna eel, tuna, crab, squid
Answer:
squid, crab, tuna, eel
Step-by-step explanation:
Just make each sushi piece into an equation, then solve it.
For example, for the squid: (s stands for squid)
[tex]2s = 3.5\\ s=1.75[/tex] Divide both sides by 2 to get "s" by itself
Eel: (e stands for eel)
e = 3.25
Tuna: (t stands for tuna)
[tex]3t=6.75\\ t=2.25[/tex] Divide both sides by 3 to get "t" by itself
Crab: (c stands for crab)
[tex]4c=8\\ c=2[/tex] Divide both sides by 4 to get "c" by itself
**Then order from least to greatest**
Answer: Squid crab tuna eel

Answer:
11 + √65
Step-by-step explanation:
The distance between A and C is 7 units; the distance between C and B is 4 units. 7 will be a and 4 will be b. The distance between A and B is c, because it is unknown.
The Pythagorean Theorem states a² + b² = c². So, if you plug in the values for a and b, you will get 7² + 4² = c² which equals 49 + 16 = c², which equals 65 = c²
Now you have 65 = c², and the only way you can solve for c is to find the square root of 65. Since 65 is not a perfect square number and therefore does not have a whole number square root, you can leave it as √65.
Now the values you have are 7, 4, and √65. Add those together and you get 11 + √65. :)
Solve by taking the square root of both sides.
3(x+ 3)^2 - 81 - 0
Answer:
x = 2.20
Step-by-step explanation:
3(x+3)^2 = 81
(x+3)^2 = 81/3
(x+3)^2 = 27
x+3 = 5.20
x = 5.20 - 3
x = 2.20
Answer:
a
Step-by-step explanation:
Given
3(x + 3)² - 81 = 0 ( add 81 to both sides )
3(x + 3)² = 81 ( divide both sides by 3 )
(x + 3)² = 27 ( take the square root of both sides )
x + 3 = ± = ± 3 ( subtract 3 from both sides )
x = - 3 ± 3
x = - 3 - 3 or x = - 3 + 3 → a
