A proportional relationship is represented by the equation 2x=18y. If y=kx, where k is the constant of proportionality, then what is the value of k?

Answers

Answer 1
2x=18y
x=9y
x=9kx


k=1/9
Answer 2
k=1/9

2x=18y

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function c(f) = 24f
represents the number of cookies, c, that can be made with f cups of flour.

What domain and range are reasonable for the function?

What do the x-intercept and y-intercept of the graph above represent in this situation?

Answers

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

Step-by-step explanation:

Given (1, 24) (8, c(f))  = 24 (8) = 192  = (1, 24) (8, 192)  Then use formula y2-y1/x2- x1 = 192-24/ 8-1 = 168/7 = 24  slope  = 24    equation = (f) = 24x The domain is all values of x that give real numbers as answers, and that is everything except 0, since 1/0 is illegal The range is all the values of y that can be reached from real values of x.

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

Explain how to compare decimals. Use the numbers 6.75 and 6.732 to help you explain this process.

tysm I am struggling

Answers

Answer:

6.75>6.732  

Step-by-step explanation:

We are given that  

6.75 and 6.732  

We have to compare two given decimal numbers.  

First we convert like decimal number  

In 6.75 there are two digits after decimal point.  

In 6.732 , there are three digits after decimal point  

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get  

6.750  

Unit place of both decimal numbers are same and tenth place of both decimal number are same.  

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3  

5 >3

Therefore, 6.750 is greater than 6.732  

6.75>6.732

to compare these decimals, we first have to turn 6.75 into 6.750, so it has the same place value as 6.732. adding a 0 to the right side of the last digit in the decimal does not change its value. now, we compare them. 6=6, 7=7, 5≠3. since 5 is greater than 3, we know 6.75 is greater than 6.732. this can be written as 6.75>6.732.

Katelyn has $1200.45 in her checking account. She spent $85.70 on groceries, paid her rent of $1000. Her grandmother sent her a check for her birthday for $85. How much money will be in Katelyn's account at the end of the month?

Answers

Answer:

$199.75

Step-by-step explanation:

Total money she has be x,

→ x = 1200.45 + 85

→ [ x = $1285.45 ]

Katelyn totally spend be y,

→ y = 85.70 + 1000

→ [ y = $1085.70 ]

Money left in Katelyn's account at the end of the month,

→ x - y

→ 1285.45 - 1085.70

→ $199.75

Hence, the money left is $199.75.

A bank pays 7% interest on 3-year certificates of deposit. What is the value of a $500 certificate after one year? Give your answer to the nearest cent.

Answers

35 I think it might be right

The value after one year will be $535.

What is interest?

Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.

Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan. For example, a bank will pay you interest when you deposit your money in a high-yield savings account.

given:

amount= $500

interest rate = 7% on 3-year certificates of deposit.

So, after one year  the value will be

=500 x 7% + 500

=500 x 0.07 + 500

= 35 + 500

= $535

Hence, the value will be $535.

Rewrite 1/5 barrel 1/2 hour as a unit rate

Answers

The answer is B, 2/5 barrel/hour.

Hope this helps! ☺️

Unit rate of (1 /5 barrel) / (1/2hour) is equals to (2/5) barrels /hour.

What is unit rate?

"Unit rate is defined as the representation of the ratio of the two different units with value of the denominator equals to 1."

According to the question,

Given,

[tex]\frac{\frac{1}{5} barrel}{\frac{1}{2} hour}[/tex]

⇒ (1 / 2) hour = ( 1/ 5) barrel

⇒ 1 hour = ( 2 / 5) barrel

⇒( 2 / 5) barrel per 1 hour

Therefore,

Unit  rate of given value is rewritten as

[tex]\frac{2}{5}[/tex] barrel / hour

Hence, Option(B) is the correct answer.
