USE FOR MASTERY Number of attempts allowed: 1 Write two rational numbers a/b and c/d, where a, b, c, and d are the digits 2, 3, 4, or 5, such that no digit can be used more than once and that the two rational numbers are the greatest distance apart on the number line. Explain how you got this answer.

Answers

Answer 1

Answer:

We want to craft:

a/b and c/d

where a, b, c and d can be 2, 3, 4 and 5.

Such that the distance in the number line between these two numbers is maximized.

Then we want one number to be really small, and the other to be really large.

Remember two things:

for numbers like a/b.

if a is smaller than b, then a/b is smaller than 1.

Now, if a is larger than b, then a/b is larger than 1.

And two things,

1/10 = 0.1

10/1 = 10

So when the numerator is larger, the distance displaced in the number line is larger.

Then we want to have:

a number where the numerator is the largest option and the denominator is the smallest option:

a/b = 5/2

And the two remaining options in such way that the numerator is smaller than the denominator:

c/d = 3/4.

The distance between these two numbers is:

D = 5/2 - 3/4 = 10/4 - 3/4 = 7/4.

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

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:

 

d.  2050

Answer:

Step-by-step explanation:

Each angle on both triangles has a set of lines, either one, two, or three. These lines are used to show congruency over a number of lines or angles. So one angle will correlate with whatever other angles have that same number of lines. For example, e and g both have two lines, this means they are corresponding and congruent.

m/n(x), x≠

Answers

When we evaluate the quotient functions, (mn)(x) for x = -3

(mn)(-3) = 9 and (m/n) (x), x ≠ 0

How did we evaluate the quotient function?

To evaluate the quotient function (mn)(x) for x = -3, we  substituting x = -3 into the function mn(x).

This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.

We then need to evaluate (m/n)(x), x ≠ 0.

This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

How to calculate unit price of something?

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Then suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

WE have been given a recipe for ice cream calls for 56 fluid ounces of milk.

We need to find How many pints of milk are there in the recipe.

There are 16 fluid ounces in 1 pint then;

56 ÷ 16

= 3.5

The answer is 3.5 pints because there are 16 fluid ounces in one pint which means that there are two pints in 32 fluid ounces and 3.5 pints in 56 fluid ounce.

Step-by-step explanation:

You can use PEMDAS to answer this question.

So first you would do whats inside the parenthesis.

4(3-1)².

3-1 is 2 so 2 would be in the parenthesis. Next you have to do exponets.

4(2)².

2² is 4. So now you just have a multiplication problem left.
