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.

After juggling for several minutes i.e., 2.5 minutes and [tex]1\frac{1}{3}[/tex] minutes (mixed fraction), the total number of bowling pins by clown is 37 pins

As per the question statement, a clown juggles 12 bowling for the first 2.5 minutes then he bump it up to an average of 18 bowling pins per minute for the last [tex]1\frac{1}{3}[/tex]  minute (Mixed Fraction form)

We are supposed to find the total number if pins by the clown.

Let's calculate the total time first that will be 2.5 minutes + [tex]1\frac{1}{3}[/tex] minutes

[tex]1\frac{1}{3} =\frac{3*1 +1}{3} =\frac{4}{3} =1.34[/tex] minutes.

Therefore total time = 3.84minutes

Given that he bumps it up to an average of 18 bowling pins per minute for the last [tex]1\frac{1}{3}[/tex]  minute so, the number of pins in the last  [tex]1\frac{1}{3}[/tex]  minute will be = [tex]18*1.34 = 24.12 = 25[/tex] (approx.)

[tex]76000\times1.08=\boxed{82,080}[/tex]

Answer:

82,080

Step-by-step explanation:

To increase a number by it's percentage, you must first extract what 8% of 76,000 is (6080). Then, you must add the original number to what is 8% of it, to get 82,080, and that, is the final answer.

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

This gives

x = 6

Hence, you need to add 6 red marbles for the ratio to stay the same

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

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

Answer:

The equation in slope-intercept form is: [tex]y=5x+32[/tex]

Step-by-step explanation:

To calculate the slope, [tex]m[/tex], we use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex] where [tex]y[/tex] are the [tex]y[/tex]-values of the points and [tex]x[/tex] are the [tex]x[/tex]-values.

Pugging our numbers into the formula, we get [tex]\frac{(-3)-12}{-7-(-4)}[/tex]. This simplifies to 5.

To calculate the [tex]y[/tex]-intercept, we first substitute one of our points into the formula. Substituting -4  and 12, we get [tex]12=5(-4)+b[/tex].

Then we can solve for [tex]b[/tex].

[tex]12=5(-4)+b[/tex]

[tex]12=-20+b[/tex]

[tex]32=b[/tex]

So, our slope is 32.

We can then plug these values into the slope-intercept form [tex]y=mx+b[/tex]

[tex]\cfrac{12}{16}\implies \cfrac{4\cdot 3}{4\cdot 4}\implies \cfrac{4}{4}\cdot \cfrac{3}{4}\implies 1\cdot \cfrac{3}{4}\implies \boxed{\cfrac{3}{4}}~\hfill \cfrac{8\cdot 3}{8\cdot 4}\implies \boxed{\cfrac{24}{32}}[/tex]

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

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

Step-by-step explanation:

Hello!

Consecutive integers are integers that come after each other. We want to find two consecutive even integers that when added give us 46.

Let the first consecutive even integer be x. Since even integers come every 2 integers (even, odd, even), the second even integer should be x + 2.

That means x + 2 should be 24.

The two numbers are 22 and 24.

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.

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
