27 is the relationship linear, exponential, or neither? Options: a. Linear b. Exponential c. Neither

Answers

Answer: Here's my answer

Step-by-step explanation:

The relationship given, 27, is neither linear nor exponential.

In a linear relationship, the dependent variable (y) changes at a constant rate for every unit increase in the independent variable (x). This results in a straight line when plotted on a graph. However, the given value, 27, does not provide any information about how the variable changes in relation to another variable. Without this information, we cannot determine if the relationship is linear.

In an exponential relationship, the dependent variable (y) changes at an increasing or decreasing rate based on a constant ratio for every unit increase in the independent variable (x). This results in a curved line when plotted on a graph. Since the given value, 27, does not provide any information about the rate of change or the constant ratio, we cannot determine if the relationship is exponential.

Therefore, based on the given information, the relationship 27 is neither linear nor exponential.

What percent of 80 is 56 ( how do i show my work for this)

Answers

Simple......................... :D

It's asking...

What percent of 80 is 56? 
----------->>>

----->>>

x*80=56

80x=56

x=(56)/(80)

=0.7

Change into a percent...(Move decimal to the right 2 places...)

=70%

Thus, your answer.

Hi there! P%=Y/X. P%=56/80. P=0.7. P%=0.7*100=70%. Therefore. 70% of 80 is 56.

Susan drove an average speed of 30 miles per hour for the first 30 miles of a trip & then at a average speed of 60 miles/hr for the remaining 30 miles of the trip if she made no stops during the trip what was susan's avg speed in miles/hr for the entire trip.(A) 35(B) 40(C) 45(D) 50(E) 55

Answers

Answer:

The correct option is B.

Step-by-step explanation:

It is given that Susan drove an average speed of 30 miles per hour for the first 30 miles of a trip & then at a average speed of 60 miles/hr for the remaining 30 miles of the trip.

Time=(Distance)/(Speed)

Time taken by Susan in first 30 miles is

T_1=(30)/(30)=1

Time taken by Susan in remaining 30 miles is

T_2=(30)/(60)=0.5

Total distance covered by Susan is

D=30+30=60

Total time taken by susan to complete 60 miles trip is

T=T_1+T_2

T=1+0.5=1.5

Susan's avg speed in miles/hr for the entire trip is

S=(60)/(1.5)=40

The average speed of susan for entire trip is 40. Therefore the correct option is B.

What is the LCD of 4 7/9 and 2 2/3?

Answers

43/9 and 24/9
Working
First rewrite the mixed numbers into improper fraction.
This gives:
43/9 and 8/3

Then find the lcm of the denominators of the fraction i.e 9 and 3
Express the fractions as x/lcm
This gives 43/9 and 24/9

Answer:

9

Step-by-step explanation:

4 7/9 = 43/9

2 2/3 = 24/9

For the denominators (9, 3) the least common multiple (LCM) is 9.

Therefore, the least common denominator (LCD) is 9.

4 7/9 = 43/9 × 1/1 = 43/9

2 2/3 = 8/3 × 3/3 = 24/9

Hope this helps :)
