How do you determine the constant rate of change from a table of x and y values.

Answers

Answer 1

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x
x
is the independent variable and y
y
is the dependent variable, then

rateofchange=changeinychangeinx

Rates of change can be positive or negative. This corresponds to an increase or decrease in the y
y
-value between the two data points. When a quantity does not change over time, it is called zero rate of change.

Selena babysits on the weekends. The equation y = 12x represents the amount of money she earns. What is the constant of proportionality?

Answers

Answer: According to the question the constant would be 12

Step-by-step explanation: Its 12 because every hour she earns 12 dollars and as the y changes so will the amount of money she earns Ex: y=2 she earns 24 dollars.

Answer - 12

Step by step- She is constantly earning 12 dollars per hour and that factor is never changing therefore it would be the constant of proportionality

The graph shows the amount of money Joe earns each hour he works. Which statement about the graph is not true?

OPTIONS:

F. The graph shows a proportional relationship.

G. The graph shows a nonproportional relationship.

H. The unit rate is $15 hour.

I. The line is straight.

Answers

Answer: G

Step-by-step explanation: the rate of change is constant, making it a proportional relationship

Answer - G
The rate is 15/1 and it's constant making it a proportional relationship therefore G would be false

Find the value of x and y

Answers

Answer:

x = 80, y = 122

Step-by-step explanation:

I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).

3/4x+2/5x-2=90°,

23/20x - 2=90°,

23/20x = 92°,

92/(23/20)

20/(1/4)

20(4)

= 80.

Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.

180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122

Row 1 should show 3 feet is equivalent to 32 inches.
Row 2 should show 6 feet is equivalent to 66 inches.
Row 3 should show 7 feet is equivalent to 84 inches.
Row 4 should show 9 feet is equivalent to 104 inches.

Answers

Answer:

Row 3 should show 7 feet is equivalent to 84 inches.

Step-by-step explanation:

First divide 36 and 3 to find the constant proportion. Which you get 12

Now multiply 12 x 3 , 12 x 6, 12 x 7, and 12 x 9

You should be able to find the incorrect answer which is row 3

12 x 7 actually equals 84 not 94

Hope this makes sense!

If you know US Customary, you will recognize that in each foot, there is 12 inches. Answer a: 12(3) is equal to 36, 12(6) is equal to 72, and 12(9) is equal to 108. Through the process of elimination, Row 3 should not be 94 inches = 7 feet; it would be 84 inches. Hope this helps!

20 30
50 75

120 ? Which statement correctly explains how to find the distance traveled after 120 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. 20 multiplied by 6 is 120, so you can multiply 30 times 6 to find the distance. 30 multiplied by 4 is 120, so you can multiply 20 times 4 to find the distance.

Its full of mischief, goofing around and candy galore. But this year, the annual October 31 festivities will probably look quite a bit different thanks to corona. Social distancing precautions will force many to alter their Halloween traditions in 2020. But that doesnt mean they wont find new ways to keep it spooky. The Centers for Disease Control and Prevention (CDC) released a list of classic Halloween activities ranked by risk levels. The agency says classic, door-to-door trick-or-treating is a high-risk activity during the pandemic. As an alternative, the agency suggests hosting a scavenger hunt-style trick-or-treat search around the house. If you do still plan to go venture out to collect candy, The Washington Post recommends taking precautions. Its recommendations include: using hand sanitizer frequently, avoiding gathering in groups and not eating candy while trick-or-treating. Also, make sure your costume includes a cloth mask. Your average costume mask might not offer the same protection against the corona virus, the CDC warns. Haunted attractions have been forced to adapt to the scary realities of 2020, as well. Salt Lake Citys Fear Factory haunted house is usually an up-close-and-personal experience. It features terrifying actors who swoop in close for a scare. This year, it will offer socially distanced frights. The scare has been completely redesigned, says Fear Factory COO Rob Dun field. We used to have animations draw customers attention so actors could pop out and startle them up close. Now, thats reversed. The costumed actors draw attention from farther away, then trigger an animation, loud noise, or air blast to go off right next to a person. In addition, drive-through haunted houses are popping up in cities around the world, including San Diego, Orlando, Houston and Tokyo. Every year has its costume trends, and 2020 will be no different. Undoubtedly, there will be many corona-themed costumes. But costume companies like Party City have also seen a jump in nurse, doctor and firefighter costumes. I think people are turning to the people who helped during the pandemic every day, says Julie Roehm, Party Citys chief marketing and experience officer. If you want a more low key and spook-free Halloween, you still have plenty of options. Sam Dominguez, a pediatrician specializing in infectious diseases, says that small groups of friends can gather outside to carve pumpkins or watch Halloween movies. But they should still wear masks and stay socially distanced. Thankfully, Halloween revelers will be able to depend on candy. This year, candy companies are preparing to sell more treats online. They are also focusing on candy that can be eaten at home, rather than passed out to trick-or-tr eaters. Already, supermarket analysts say the sale of chocolate and candy is up 13 percent from 2019. Everyones been cooped up in the house, so people are looking for something to celebrate, says Katie Thomas, a consumer trends analyst at the Barney Consumer Institute.
