Answer:
x = 10
Step-by-step explanation:
This is because the formula of the area of a triangle is b x h divided by 2.
Since 8 is the base, you have to find what to multiply it by to get 80 (since 80 divided by 2 is the answer, 40).
80 divided by 8 is 10, therefore the base, or x, is 10.
You can put it in the formula to double check and it will equal 40.

Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 120.
A rectangle has a width of x and a length of x plus 4.
Answers
Answer:
Inequality : 4x+8 < 120
x<28
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P)= 2 length +2 width
Where:
Width = x
Length = x+4
Replacing with the values given
P = 2 (x+4) + 2x
P = 2x+8+2x
P=4x+8
Since the perimeter of the rectangle must be less than 120:
4x+8 < 120
Solving for x
4x<120-8
4x<112
x<112/4
x<28
Feel free to ask for more if needed or if you did not understand something.
To find the values of x for which the perimeter of a rectangle is less than 120, you would solve the equation 2*(x + (x+4)) < 120. After simplifying and solving, the result is x < 28.
Explanation:In this problem, you are asked to find the values of x for which the perimeter of a rectangle is less than 120. The rectangle has width of x and a length of x plus 4.
The perimeter of a rectangle is defined as 2*(length + width). Plugging the lengths in for our rectangle, we get 2*(x + (x+4)) < 120. Simplifying this inequality gives 2*(2x + 4) < 120
From there, you want to distribute the 2 across the equation, which gives 4x + 8 < 120. Subtract 8 from both sides to get 4x < 112, and then divide both sides by 4 to find x < 28. So, the possible values of x are those less than 28.

What is the mean absolute deviation of the data set? 8, 5, 12, 4, 5, 8, 7 1 2 5 7
Answers
The mean absolute deviation (MAD) is a measure of the spread of a data set, calculated as the average of the absolute deviations of each data point from the data set's mean. For the given data set, the MAD is approximately 2.42.
The mean absolute deviation (MAD) of a data set is a measure of variability that represents the average difference between each data point and the mean of the data set. To calculate MAD, follow these steps:
Calculate the mean (average) of the data set.Calculate the deviation of each measurement, which is the absolute value of the difference between each measurement and the mean.Sum all the absolute deviations.Divide the sum by the number of data points in the data set to get the MAD.For the data set 8, 5, 12, 4, 5, 8, 7, 1, 2, 5, 7, the mean is 5.8 (sum of all numbers divided by the number of numbers). Here are the deviations from the mean:
|8 - 5.8| = 2.2|5 - 5.8| = 0.8|12 - 5.8| = 6.2|4 - 5.8| = 1.8|5 - 5.8| = 0.8|8 - 5.8| = 2.2|7 - 5.8| = 1.2|1 - 5.8| = 4.8|2 - 5.8| = 3.8|5 - 5.8| = 0.8|7 - 5.8| = 1.2Summing all the absolute deviations gives us 26.6. With 11 data points, the MAD is 26.6 / 11 = 2.42.

Answer:
C
Step-by-step explanation:
Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:
A). When x is an absolute value, the line will not be linear because an input will have two outputs.
B). x cannot be in the denominator of a fraction for the line to be linear
D). Once again, x cannot be an absolute value.
*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.

4. Do you think a binary code can be transmitted by light, sound, or radio waves, or only by using an electrical current? Explain your answer.
Answers
Answer:
Yes, they came up with the telegraph, which transmits through radio waves. Binary code could probably also be transmitted in light, sound, or radio waves.
Binary code can be transmitted through light, sound, and radio waves, not just electrical current. These transmissions use AM, FM, and phase modulation, with light waves as the most efficient for high-speed data transfer.
Binary code can indeed be transmitted through various mediums besides just electrical current. This includes light, sound, and radio waves. Radio waves do indeed belong to the electromagnetic spectrum just like light waves do but with lower frequencies. Thus, a radio detects these electromagnetic waves, not light in the visual sense, and converts them into sound waves we can hear.
Light waves, unlike sound waves, do not need a physical medium to travel; they can move through a vacuum, transmitting information efficiently as electromagnetic waves. This is the principle behind fiber optic cables, which use pulses of light to transmit information encoded as binary code at high speeds. The rate at which information can be transmitted on an electromagnetic wave is proportional to its frequency, explaining why high-frequency laser transmissions in fiber optics can carry more conversations than lower-frequency electronic transmissions in wires.

What is the value of x in the equation 1.5(x + 4) - 3 = 4.5(x - 2)?
Answers
Answer:
x=4
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
Distribute
1.5x + 6 -3 = 4.5x - 9
Combine like terms
1.5x +3 = 4.5x -9
Subtract 1.5x from each side
1.5x -1.5x +3 = 4.5x -1.5x-9
3 = 3x-9
Add 9 to each side
3+9 = 3x-9+9
12 =3x
Divide each side by 3
12/3 = 3x/3

Justin states that the ratio is 4:1.

Justin is correct because there are 4 students per table. A ratio is not correct unless it uses the smallest possible numbers.
Desiree is correct because there are 24 students to 6 tables in the room. A ratio must account for the total number of each value.
Both are correct. Desiree’s ratio compares the total number of students in the room to the total number of tables, while Justin’s is equivalent but simplified to students per table.

3 balls in the smallest hole, 3 balls in the bigger hole, and 4 balls in neither hol
Answers
Answer: 4 balls in the smallest hole and 8 balls in the bigger hole
Explanation: Since 1 ball in the smallest hole in worth 100 points and 4 balls in the smallest hole, then we multiply 4 by 100 to get 400. And also, every ball that doesn't make either one of the holes, it counts as 1 point , so we multiply 1 by 6 to get 6. Finally add up 400 and 6 to get 406, more than his current score.

George sold 18, 22, 26, 12, 25, 20, and 19 cars per month over the past seven months. He followed the steps below to determine the number of cars he needs to sell in the next month to have a mean number of sales per month of 24.
Step 1: Find the total cars needed to have a mean of 24: 24 times 7 = 168.
Step 2: Find the total cars sold: 18 + 22 + 26 + 12 + 25 + 20 + 19 = 142.
Step 3: Subtract the total cars sold from the total cars needed: 168 minus 142 = 26.
Step 4: State the answer: George needs to sell 26 cars next month.
Where did George make his first mistake?
Step 1
Step 2
Step 3
Step 4
Answers
George made his first mistake in Step 1 by calculating the mean for 7 months instead of 8. The correct calculation should be 24 times 8 to find the total number of cars he needs for an 8-month period.
The student has asked where George made his first mistake in determining how many cars he needs to sell to have a mean number of sales of 24 per month. Reviewing the steps he took, it is important to ensure the right number of periods is considered. In this case, if George is calculating the mean across 8 months rather than 7 months, as 7 months have passed and he needs the average after the next month (the 8th), he made his first mistake in Step 1 where he calculated 24 * 7 instead of 24 * 8. Therefore, the correct calculation should be 24 times 8 which equals to 192. This is the total number of cars he needs to have sold over the 8 months, to achieve a mean of 24 cars sold per month.
