Answer:
4400
Step-by-step explanation:
I think this is right sorry if its not. Have a good night, sorry if im late.
Answer:
4600 miles
Step-by-step explanation:
You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.
Miles per hourThe speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...
A speed - B speed
45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h
Explorer B travels 4600 fewer miles in an hour than Explorer A.

Several trials are performed with the results shown in the table. What is the experimental probability of randomly drawing a green marble?
Red Blue Green
10 12 28
What is the experimental probability of randomly drawing a green marble?
What is the theoretical probability of randomly drawing a green marble?
What would you expect to happen if more trials of the experiment are performed? Explain your reasoning using complete sentences.
Answer:
experimental
\(p(green \: mable) = ( \frac{5}{24} \times \frac{8}{24} \times \frac{11}{24} ) \\ = 0.03\)
theoretical
\( p(green \: mable) = \frac{12}{25} \\ = 0.48\)

A. x = -6
B. x = 15
Step-by-step explanation:
A.
\(\frac{x}{3}-5=-7\\\frac{x}{3}-\frac{15}{3}=-7\\\frac{x-15}{3}=-7\\x-15 = -7*3\\x-15=-21\\x=-21+15\\x=-6\)
B.
\(\frac{x}{2}-5=2.5\\\frac{x}{2}-\frac{10}{2} = 2.5\\\frac{x-10}{2}=2.5\\x-10= 2.5*2\\x-10=5\\x=5+10\\x=15\\\)

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)
Answer:
Part A: 0,6 1, 5.5 2,5.0 3,4.5 4,4.0 5,3.5 6,3.0

Part C: 0,6 1,5.7 2,5.4 3,5.1 4,4.8 5,4.5 6,4.2, this would still be a function, just at a slower rate of speed.

A.
x < 15
B.
x > 15
C.
x = 15
D.
x < 12
Answer: A
Step-by-step explanation:
Let x represent the number of stripes on Penny's cat
< is less than
The number of stripes is less than 15
x < 15
Answer:
B , x > 15
Step-by-step explanation:
The symbol < is used to compare to amounts. The same it opens to is the side with the larger amount.
Example:
6 < 7
Because the information given is that the number of stripes on Penny's Cat is more than 15, you would set up the inequalities where x would be the larger amount, with x representing the amount of stripes on Penny's cats

Given: a||b and c||d, m∠4=35°
Find: m∠1, m∠2, and m∠3
The measure of the angles m∠1, m∠2 and m∠3 are 145°, 35° and 35° respectively.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
m∠2 = m∠4 = 35° (corresponding angles are equal)
m∠2 = m∠3 = 35° (corresponding angles are equal)
m∠1 + m∠3 = 180° (base angles are supplementary)
m∠1 + 35 = 180
m∠1 = 145°
The measure of the angles m∠1, m∠2 and m∠3 are 145°, 35° and 35° respectively.

Answer:
Step-by-step explanation:
Let’s mark the Triangle Points as Point A, Point B, Point C.
Point A = 1x°
Point B = 2x°
Point C = 3x°
We know that the Angle Sum of a Triangle is equal to 180°.
So, Point A + Point B +Point C = 180°
= 1x° + 2x° + 3x° = 180°
= (1 + 2 + 3)x° = 180°
= 6x° = 180°
= x° = (180/6)°
= x° = 30°

Eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily:
A scatter plot is shown with the title Lemonade Sales. The x-axis is labeled High Temperature, and the y-axis is labeled Cups of Lemonade Sold. Data points are located at 30 and 4, 40 and 6, 40 and 8, 50 and 2, 55 and 10, 65 and 14, 70 and 16, 75 and 14, 85 and 19, 90 and 20.
Part A: Describe the relationship between the temperature of the city and the number of cups of lemonade sold. (I already know this one)
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept. (3 points)
Answer: m = ~1/5 ; b = ~-8
Step-by-step explanation:
*Important: The **approximate** line of best fit will change depending on which points you choose.
What we know:
The line of best fit is positiveThe line must be in slope-intercept formWe must find the y-intercept and slope equationHow to solve:
Finding a completely accurate line of best fit is a job best for computers. This tutorial is assuming that we must choose 2 points. A line of best fit can also be found via eyeballing it, but this is not what is being asked here.
Process:
Write slope equation (y2 - y1)/(x2 - x1)Choose points ie. (90, 20) (70,16)Subsitute (20-16)/(90-70)Simplify 4/20Slope = 1/5
Solving for y-intercept
Write slope-intercept equation y = mx + bSubsitute (Choose a point) 2 = 1/5(50) + b Simplify 2 = 10 + bIsolate variable -10 -10-8 = b
y-intercept = -8
Solution: m = ~1/5 ; b = ~-8
"The approximate line of best fit can be found by using two of the points listed in a slope equation."

-294 ÷ -14. Please show your work!!!!!
Answer:
21
Step-by-step explanation:
To solve the problem you can just leave the negatives behind for a while.
You then divide 294 by 14 using the normal method of division you prefere.
The answer you get is 21.
So now when the signs of the numbers are the same (negative or positive) The answer after dividing is always a positive number thus the answer remain 21.
HOPE IT HELPED
Answer:
Ignore any negative sign for now.
294÷14
Use the algorithm method.

Now consider the signs. Two negatives make a positive
