Why is it useful to write a ratio of fractions as a unit rate

Answers

Answer 1

Answer:

The unit rate has a denominator of one.This will often modify any subsequent mathematical calculations. Choosing the form of the proportion should really be based on what you're doing with it. Often a denominator apart from 1 is sufficient to follow-up operations that you will need to run.

Answer 2
A "unit rate" has a denominator of 1. That will often simplify any subsequent math operations.

The choice of the form of a ratio should be made based on what you need to do with it. Sometimes, a denominator other than 1 is appropriate to follow-on operations you may need to perform.

Evaluate xy for x = –9 and y = 5.
A –4
B 45
C –45
D –14

Answers

Answer:

C

Step-by-step explanation:

9 times 5 is 45. when ur multiplying and there's only one negative sign, the answer will always be negative.

C. -45

These types of problems can be fairly simply once you understand substitution. Substitution is when we put in values (in this case -9 and 5) in their set variable (x and y in this case.)

The problem states that x=-9 therefore we put in -9 for x in the multiplication of xy so it looks like this: (-9)(y). Next we want to substitute in the y value which is 5 so that we now have (-9)(5).

Because there is no plus or minus sign, along with a division sign, we then MULTIPLY these two numbers because the variables are connected so -9*5 would equal to -45.

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level.

NO SAMPLE RESPONSES FROM ED PLEASE

Answers

Answer:

The total variation in water level is -3.3

Step-by-step explanation:

Round 1.05 mm to the nearest whole number the result is -1.1 then round 2.48 which the result will be equal to 3. The total variation in water level is -3.3

The total variation in water level is -2.6.

We have,

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years.

The decrease of the rate -1.05 mm/year can be rounded to -1.

Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Thus, the total variation in water level is -2.6.

Solve this equation.
24 + 0.44x = 19 + 1.69x
x = 4
x = 0.44
x = 5
x = 5.4

Answers

Answer:

X = 4

Step-by-step explanation:

All you have to do is plugin 4 where x is and solve and each side will equal the same.

The solution of the given equation 24 + 0.44x = 19 + 1.69x will be x = 4 thus option (A) will be correct.

What is the equation?

There are many different ways to define an equation.

More than one variable may be present inside a linear equation.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

As per the given equation,

24 + 0.44x = 19 + 1.69x

24 - 19 = 1.69x - 0.44x

5 = 1.25x

x = 4

Hence "The solution of the given equation 24 + 0.44x = 19 + 1.69x will be x = 4".

Name a combination of coins that is 130% of the value of a dollar.

Answers

Answer:

5 quarters, 1 nickel  

Step-by-step explanation:

A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given: A dollar and to find its 130% equivalent in the form of coins.

A nickel is worth 5 cents

A dime is worth 10 cents

A quarter is worth 25 cents

Now a dollar is equivalent to 100 cents

Thus 130% of a dollar is equivalent to

130/100 ×100 +100 =230 cents

Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents  as

8×25+2×10+2×5=230 cents.

Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
