Step-by-step explanation:

The older the kids get, the less you have to change their diapers. Therefore, that is why the graph is going down

The total laps your friend runs is 3.

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A proper fraction is a fraction where the numerator is less than the denominator. A mixed fraction is a fraction that is made up of a whole number and a proper fraction.

The first step is to determine the total miles you run

Total miles run  = length of the side walk x total number of laps

9/10 x (3 + 2)

9/10 x 5 = 45 / 10 = 4.5 miles

The second step is to determine the total number of laps she runs:

4.5 miles / 1 1/2 miles

4.5 / 1.5 = 3 laps

Part a: Resulting mixture: 92.2 milliliters.

Part b: Percentage of acid in the resulting mixture = 36.88%.

Part a: Find the both values from the given percentage;

225 millilitres of a solution contains is 39% acid.

39% of 225 = (39×225)/100 = 87.75 millilitres.

Now, 25 milliliters of a solution contains is 19% acid.

19% of 25 = (19×25)/100 = 4.75 millilitres.

Mixture solution = 87.75 + 4.75

Mixture solution = 92.2 milliliters of acid.

Part b: percentage of the resulting mixture is acid.

92.2 milliliters of the total 250 milliliters is acid.

= 92.2/250 × 100

= 36.88 %

Thus, 36.88% of the the resulting mixture contains acid.

If total revenue given by the function R=16.5x and has total cost given by C=14x+400, where x is the number of items produced and sold then the number of units that gives break even for the product is 160.

In mathematics, a function is an expression, rule, or law that specifies a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are commonplace in mathematics and are required for expressing physical relationships in the sciences. The present concept of function was proposed by German mathematician Peter Dirichlet in 1837.

If a variable y is so tied to a variable x that there is a rule that determines a unique value of y whenever a numerical value is assigned to x, then y is referred to as a function of the independent variable x.

If the manufacturer will break even for the products then

Revenue = Cost

F(R) = F(C)

14x+400 = 16.5x

On solving the equation

16.5x - 14x = 400

2.5x = 400

x = 400/2.5

x = 160

In the graph the value of x is 160 as well

Answer: x=68

Step-by-step explanation:

(x-5)/3=21

(x-5)*3/3=21*3     ==> Multiply both sides by 3 to remove fractions

x-5=21*3

x-5=63

x+5-5=63+5     ==> Add 5 on both sides to isolate the x variable

x=63+5

x=68

Let's solve the problem,

→ (x - 5)/3 = 21

→ x - 5 = 21 × 3

→ x = 63 + 5

→ [ x = 68 ]

Hence, the value is 68.

Given that the expression is 6-3/6-4.

We are required to find the value after simplification.

Simplification or simplify fractions basically means to simplify a complicated mathematical expression to get a single or direct answer.

We have to use BODMAS rule for the simplification. The full form of BODMAS is Brackets, Open, Division, Multiplication,Addition and Subtraction. Simplication is nothing but to reduce the expression.

The expression is  6-3/6-4.

We have to do division first.

Step-by-step explanation:

The required radius and error in radius is 13.8 cm and ± 0.12cm

Given that,
A machinist is required to manufacture a circular metal disk with an area of 600cm².
(a) What radius produces such a disk is to be determined
(b) If the machinist is allowed an error tolerance of ±5cm2 in the area of the disk, how close to the ideal radius in part is to be determined.

The area of a circle is given by the pie times square of the radius.

Area of circle = πr^2

Here,
a) The given area of disk = 600 cm²
   πr² = 600
   r = √600/3.14
   r = 13.8 cm

b) an error tolerance of ± 5 cm² in the area of the disk,
So the percentage of error is 0.84%
Now, 0.84% of radius = 0.84 *13.8/100 = 0.12
The required error in radius will be ±0.12 cm

Similarly,
c) limx→a f(x) = L
Where a is the area of the disk and L is length, and f(x) is function of area.

Thus, the required radius and error in radius is 13.8 cm and ± 0.12cm.

You need to add 6 red marbles for the ratio to stay the same

The given parameters are:

Black = 6

Red = 4

Represent as ratio

Ratio = Red : Black

This gives

Red : Black = 4 : 6

When you add 4 red marbles, we have:

4 + 4 : 6 + x = 4 : 6

Where x represents the additional number of black marbles

This gives

8 : 6 + x = 4 : 6

Multiply 4 : 6 by 2

So, we have:

8 : 6 + x = 8 : 12

By comparing both sides, we have

6 + x = 12

it's a quadratic equation so the parent function is x^2.

The average speed of person during her commute is 28 miles/ hour.

What do you mean by average speed ?

The entire distance that an object travels in a given amount of time is defined as the average speed for that object.

Total time of driving is 12 minutes.

This can be written as hours which will be :

= 12 / 60

= 1/5 hour

Time of stopping at red lights is 3 minutes and speed is 35 miles per hour.

So , the total distance using the formula will be :

Total distance = Speed × time

Here , the time taken will be equal to :

= [(12 + 3) / 60]

= 15 / 60

= 1/4 hour

So ;

Total distance = 35 × (1/4 hour)

Total distance = 7 miles

And the average speed will be ;

Average speed = Distance / Time

or

Average speed = 7 miles / (1/4) hour

Average speed = 7 × 4 miles/hour

Average speed = 28 miles / hour

Therefore , the average speed of person during her commute is 28 miles/ hour.

Part A  The quadratic expression in factored form is 2t(19 - 8t)

Part B The height of the soccer ball 1.25 seconds after Callie kicks it is 22.5 ft

Since Callie kicks a soccer ball from the ground. The height of the ball, in feet, above the ground t seconds after the ball is kicked can be represented by the expression 38t- 16t².

So, the expression is a quadratic expression, we have that h(t) = 38t- 16t².

To write the expression in factored form, we find the common factors of both terms and factor them out.

So,  h(t) = 38t- 16t²

= 2 × 19 × t - 2 × 8 × t × t

Factoring out 2 and t, we have

= 2 × t × (19 - 8 × t)

= 2t(19 - 8t)

So, the quadratic expression in factored form is 2t(19 - 8t)

Since the quadratic expression h(t) = 38t- 16t² represents the height of the ball above the ground in feet, to find the height of the ball after 1.25 second,we substitute t = 1.25 s into the expression.

So, h(t) = 38t- 16t²

h(1.25) = 38(1.25) - 16(1.25)²

h(1.25) = 47.5 - 16(1.5625)

h(1.25) = 47.5 - 25

h(1.25) = 22.5 ft

So, the height of the soccer ball 1.25 seconds after Callie kicks it is 22.5 ft

The function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The function that models the path of the first kick is given as

y = -0.02(x - 0.30)^2 + 18

A quadratic function is represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

In this case, the interpretation of the vertex is

Vertex = (Horizontal distance, Maximum height)

Using the above as a guide, we have

Vertex = (30, 18)

This means that

Horizontal distance = 30

Maximum height = 18

For the second ball, we have

This means that

Horizontal distance = 30

Maximum height = 18 + 6

Evaluate

Horizontal distance = 30

Maximum height = 24

So, the function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

Hence, the function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

According to the question we have been given that

The height of the small plant = [tex]2\frac{1}{2}[/tex] inch

In  1 week the plant grows = [tex]\frac{3}{4}[/tex] inch

We need to find the height of the small plant after 3 weeks.

For that we will first find how much tall it will be in 3 weeks using unitary method that is,

                              1 week = [tex]\frac{3}{4}[/tex] inch

                               3 week = [tex]\frac{3}{4}[/tex]  * 3 inch

                                          = 9/4 inch

Therefore the height of the small plant after 3 weeks will be

                         [tex]=2\frac{1}{2} + \frac{9}{4} \\= \frac{5}{2} + \frac{9}{4}\\= \frac{10+9}{4} \\= \frac{19}{4}[/tex]

hence the height is 19/4 inch
