A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft from the water in 2000. In what year will the house be only 250 ft from the water?

a. 1990

c. 2015

b. 2004

d. 2050

Answers

Answer 1

We develop an equation for the given situation by first writing the general equation for lines,

                                y = mx + b

Substituting to this given the values given above,

(1990)                      430 = b

(2000)                      400 = m(10) + 430

The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,

                              y = -3x + 430

Answer 2

d.  2050

One math student, John, can solve 6 math problems in 20 minutes while another student, Juaquine, can solve the same 6 math problems at a rate of 1 problem per 4 minutes. Who works faster?
1.John
2.Juaquine

Answers

Answer:

John

Step-by-step explanation:

6/20=0.3

1/4=0.25

Juaquine is solving problems at a faster rate as compared to John.

What is the rate?

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

As per the question, we can compare their rates of problem-solving by calculating the number of problems they can solve per minute.

For John, this is 6 problems / 20 minutes = 0.3 problems per minute.

For Juaquine, this is 6 problems / (4 minutes/problem) = 1.5 problems per minute.

Since Juaquine can solve 1.5 problems per minute compared to John's 0.3 problems per minute, Juaquine is solving problems at a faster rate.

Hence, Juaquine works faster as compared to John.

18:9 as 1:n where n is a decimal?

Answers

Answer:

18 : 9 is the same thing as 18/9.

So if we want 1 : n  = 1/n

(18 / 18) / (9 / 18)

=> 1 / 0.5

=> 1 : 0.5

Therefore, n = 0.5 is the solution of the equation.

Thanks!!

Answer:

n = 0.5

Step-by-step explanation:

To answer this question, we must first figure out the ratio 18:9.

What is 18 compared to 9?

If you said that 18 is double the amount of 9, or that 9 is half of 18, you are correct.

Using this logic, we then need to make the variable 'n' in 1:n half of 1 in decimal form.

So, what is half of 1 in decimal form?

If you said 0.5 OR 0.50, you are correct! And that is your answer !

Hope this helps :)
