Step-by-step explanation:

0.21 as a fraction in simplest form is 21/100.

In Mathematics and Geometry, a fraction simply refers to a numerical quantity (numeral) which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

In this exercise and scenario, we would convert the given decimal number 0.21 into a fraction by converting it into a percentage as follows;

0.21 = 21/100

Fraction: 21/100 = 0.21.

The volume of the recycling bin will be 429 m³.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The bin is 12 meters long, 5 1/2 meters wide, and 6 1/2 meters tall.

Now,

Since, We know that;

The volume of right rectangular = Length x Width x Height

Hence, The volume of right rectangular prism = 12 x 5 1/2 x 6 1/2

                                                                       = 12 x 11/2 x 13/2

                                                                       = 3 x 11 x 13

                                                                       = 429 m³

Thus, The volume of the recycling bin will be 429 m³.

It would take 1.8 years to to get $992 with a 6% simple interest annually.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.

Simple Interest = (Principal × Rate × Time) / 100

Given that man deposited $800 in his account at a bank which offers 6% simple interest per annum.

Principal =  $800

Rate = 6%

Time = 9

Simple Interest = (Principal × Rate × Time) / 100

Simple Interest = (800× 6× 9) / 100

Simple Interest = 432 dollar

Also, Simple Interest = (Principal × Rate × Time) / 100

$992 = (800 × 6× Time) / 100

992 = 48× Time

Time= 20.6

Answer:(-4,-2)

Step-by-step explanation:

Broderick initially has $420, adds $213 from deposits, and needs $1,243 for checks, resulting in him needing to add $610 to cover his checks.

To calculate how much money Broderick needs to add to his account to cover his checks, we must first figure out his total deposits and then subtract the total amount he needs for the checks.

Broderick starts with $420 in his account and makes 6 deposits of $35.50 each. To find the total amount deposited, we multiply the number of deposits by the amount of each deposit:

Adding this total to his initial amount gives us:

Next, Broderick needs to write 4 checks for $310.75 each. The total amount for the checks is:

To determine how much additional money is needed, we subtract Broderick's available money from the total amount needed for the checks:

Therefore, Broderick needs to add $610 to his account to cover the checks.

Step-by-step explanation:

Either the IQR or the range are good measures of variability because the distribution has no outliers.

The required negative numbers are -5 and -7.

The quadratic equation is defined as a function containing the highest power of a variable is two.

Let the required negative numbers be x and y.

The sum of the square of two negative numbers is 74.

(x)² + (y )² = 74

x² + y² = 74

(x)² - (y)² = 24

y² - x² = 24

y² = x² + 24

Substitute the value of y² = x² + 24 in the equation x² + y² = 74,

x² + 24 + x² = 74

2x² = 74 - 24

2x² = 50

x² = 25

x = √25

x = ±5

x = 5, -5

Take the negative value as per the question.

Substitute the value of x = -5 in the equation y² = x² + 24,

y² = (-5)² + 24

y² = 25 + 24

y² = 49

y = √49

y = ±7

y = - 7

Therefore, the required negative numbers are -5 and -7.

Final answer:

The problem is solved by converting the given conditions into a system of equations, which is then solved to find the two negative numbers. The numbers obtained, -3 and -27, satisfy both given conditions.

Explanation:

The question provided is a mathematical problem involving the determination of two negative numbers given that their squares sum to 74 and their difference is 24. Let's denote the smaller number as x and the larger number as y. The given conditions can be represented by two equations: [tex]x^2 + y^2 = 74[/tex] and y - x = 24.

To find the values of x and y, we solve these equations simultaneously. First, use the second equation to express y in terms of x:

y = x + 24

Then, substitute this expression for y into the first equation:

[tex]x^2 + (x + 24)^2 = 74[/tex]

This simplifies to a quadratic equation in x, which can be solved to find the value of x, and subsequently, y can be determined using the expression

y = x + 24.

After solving the quadratic equation, you find that the two negative numbers are -3 and -27, satisfying both the sum of their squares equaling 74 and their difference being 24.

The smallest number is 90.63

We have three different two digit numbers total is 286.

We have to determine the smallest of the three numbers.

The two digit numbers can be in only in range of 1 to 99.

While a three digit number can be in range from 100 to 1000.

Hence, the two-digit number is smallest.

According to the question -

Let's assume that the three numbers are -   x, y and z.

Now -

x + y + z = 286

If we assume three equal two digit numbers will together make 286, than each two digit number will be = [tex]\frac{286}{3}[/tex] = 95.33.

In this case -   x = 95.33     y = 95.33       z = 95.33

Now, subtract 95.33 from 100 = 100 - 95.33 = 4.7

Assume, that we take 4.7 out from x, then x will be equal to -

x = 95.33 - 4.70 = 90.63

And divide 4.7 equally to both y and z -

y = z = 97.6

However, you can divide the 4.7 in any ratio among the numbers y and z for getting different numbers. Since we are focused on finding the smallest number of three we will not do it here.

Hence, the smallest number is x = 90.63

The student's question pertains to the mathematical analysis of motion, specifically through the interpretation of velocity versus time and position versus time graphs related to cycling activities and races.

The question involves interpreting graphs that represent the velocity versus time and position versus time of two individuals riding bicycles and a race between friends. Students in middle school are often introduced to concepts of speed, velocity, and displacement and are tasked with analyzing graphs to understand these concepts in a practical scenario. The problem sets mentioned, including the velocity-time graphs, position-time graphs, and measurements of motion through various activities such as biking or collision events, are all connected to the mathematical analysis of motion in physics. By understanding how to read these graphs, students can determine factors such as constant velocity, average speeds, displacement, and the outcomes of simple collisions. These skills are essential in developing an understanding of kinematics, which is a branch of classical mechanics that describes the motion of points, objects, and systems of bodies without considering the causes of motion.

When counting $5 bills, the values are $5, $10, $15, $20, $25, $30 with a pattern in the one digits of 5, 0, 5, 0, 5, 0. This demonstrates the pattern of addition with multiples of five.

Marvin is counting $5 bills, hence each time he counts a bill the total value increases by $5. The values Marvin counts are $5, $10, $15, $20, $25, $30.

The one digits in these values form a pattern, specifically, they are 5, 0, 5, 0, 5, 0.

This pattern repeats every two counts: a 5 followed by a 0. This is because adding 5 to a multiple of 10 results in a number ending in 5, and adding another 5 results in another multiple of 10, which always ends in 0.
