For the following, based on the information given which would you use to find the missing variable?

The solved answer for the given fraction expression in will be 2.6833.

What is a fraction?

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

Given X = 1/3

Y = 3/5

Z = 2 1/4 = 9/4

The value of X*Y*Z = (1/3*3/5*9/4)

= (20+36+105)/60

=161/60

=2.6833

Hence the solved answer for the given expression will be 2.6833.

According to the concept of quadratic equation, the minimum cost for the x ray machine is $17, 484

Quadratic equation:

Basically, the polynomial equation with highest degree of two is called a quadratic equation.

The general equation is given by ax² + bx + c = 0, where a ≠ 0.

Given,

A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made. If .x machines are made, then the unit cost is given by the function C (x)=0.5x²-320x+68,684.

Here we need to find the minimum unit cost.

Here we know that the standard form of a quadratic is given by:

=> ax² + bx + c

From this function, we have to calculate the value of x as,

=> x = -b/ 2a

While we compare the standard form with the given function,

=> C (x)=0.5x²-320x+68,684.

Then we get the value of

=> a = 0.5

=> b = -320

=> c = 68,684

So, the value of x is calculated as,

=> x = -(-320) / 2(0.5)

=> x = 320 / 1

=> x = 1

Now, we have to plug this value into original function would give us the minimum (unit cost):

=> C(320) = 0.5(320)²- 320 (320) + 68,684.

=> C(320) = 0.5(102400) - 102400 + 68, 684

=> C(320) = 51200 - 102400 + 68684

=> C(320) = 17, 484

Therefore, the minimum unit cost is $17, 484

The equation of the line that passes through the point P(1/3,4) and has no slope is y = 4.

According to the question,

We have the following information:

Point through which line is passing = (1/3,4)

Slope of the line = 0

We know that the following formula is used to find the equation of the line passing through a point:

y-y' = m(x-x')

We have x' = 1/3 and y' = 4.

y-4 = 0(x-1/3)

y-4 = 0

Adding 4 on both sides of the equation:

y = 4

Hence, the equation of the line that passes through the point P(1/3,4) and has no slope is y = 4.

He needs 10 litres of solution of 40% and 20 litres of 70% solution to make 30 litres of 60% acid solution.

According to the question,

We have the following information:

Gabe Amodeo, a nuclear physicist, needs 30 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution.

Now, let's take x litres of 40% solution and y litres of 70% solution.

So, we have the following expressions:

x+y = 30

x = 30-y ....(1)

40x/100 + 70y/100 = 30*60/100

Dividing 100 on the numerator by 100 on denominator:

40x+70y = 1800

Dividing both sides by 10:

4x+7y = 180

Putting the value of x from equation 1:

4(30-y)+7y = 180

120-4y+7y = 180

120+3y = 180

Subtracting 120 from both the sides:

3y = 180-120

3y = 60

y = 60/3

y = 20

Now, putting this value of y in equation 1:

x = 30-y

x = 30-20

x = 10

Hence, he needs 10 litres of 40% solution and 20 litres of 70% solution to make 30 litres of 60% acid solution.

The value of h in the given polygon is 34.8°

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides or edges of a polygon are made of straight line segments connected end to end to form a closed shape. The point where two line segments meet is called vertex or corners, and subsequently, an angle is formed. If a polygon contains congruent sides, then that is called a regular polygon.

The sum of the interior angles of a regular polygon = (n - 2) x 180

where n = number of sides of the polygon

here n = 20

Sum of the interior angle = (20 - 2) x 180

Sum of the interior angle = 3240°

which also means that 20(5h - 12) = 3240

100h -240 = 3240

100h = 3240+240

100h = 3480

h = 3480/100

h = 34.8°

In conclusion, the value of h = 34.8°

To answer this question we will use The Linear Programming concept

The formula for the moose population is

The moose population in 2006 would be

We use the year 1990 as the base year for creating the equation of the moose population. We could assume that:

The moose population of the year: P(x)

The moose population in year 1990: a

The year difference to 1990: x

The linear change of the moose population: b

Hence, we could make some assumption about the relationship between each elements mentioned above, where the moose population of the year would be depends on the linear change of the population added into the original moose population in year 1990. We could write this relationship into the equation (i):

P(x) = a + bx ... (i)

Using data provided from the question, we could make some other equations and find the value of b:

P(x) = a + bx

P(4) = a + 4b = 3280 ---> year 1994 ... (ii)

P(7) = a + 7b = 4120 ---> year 1997 ... (iii)

We could do some eliminations between equations (ii) and (iii)

3280 = a + 4b

4120 = a + 7b -

840 = 3b

b = 280 ... (iv)

After finding the value of b, we could subtitute its value into equation (ii) to find the value of a:

3280 = a + 4b

3280 = a + 4(280)

3280 = a + 1120

a = 2160 ... (v)

After finding the value of a and b, we could rewrite the equation (i) by inserting the and b values.

P(x) = a + bx

P(x) = 2160 + 280x ... (vi)

Next, we will predict the moose population to be in 2006.

First, we should determine the value of x, the difference between the year 2006 to the base year 1990.

x = 2006 - 1990

x = 16 ... (vii)

We would subtitute the equation (vii) into equation (vi) to predict the moose population to be in 2006:

P(16) = 2160 + 280(16)

P(16) = 6640...(viii)

Step-by-step explanation:

a) At t = 0days : 300insects

b) The growth rate is 5.12% each day.

c) Population after 10days: P(10) =494.61

d) The population to reach 420 is equals roughly 70.129 hours

e) The insect population double in  t=6.020 days , which is 144.48 hours.

What is Population?

Any whole group that shares at least one trait is referred to be a population. People do not make up all populations. Populations can include, but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.

Given: t in days, P(t)=300e(0.05t).

(a) The total number of insects at time t=0 days is equal to

P(0)=300(1)

P(0) =300.

(b) The growth rate is calculated as the percentage increase over time, which is equal to-

P(t+1)/P(t)=300e(0.05(t+1))/300e(0.05t)

P(t+1)/P(t) =e^(0.05(1))

P(t+1)/P(t) =1.0512

Therefore, the growth rate is 5.12% each day.

(c) Population after 10 days.

P(10)=300e^(0.05*10)

P(10) =300(1.6487)

P(10) =494.61

(d) When P(t)=420, the population will reach 420,

or 300e0.05t=420,

take log

0.05t=log(1.4), or

t = 2.922 days,

for the population to reach 420.

equals roughly 70.129 hours

(e) When P(t)=2*300=600 the population will double.

300e^(0.05t)=600

=> e^(0.05t)=600/300=2

Take log

(log 0.05t=log(2)),

t=6.020 days , which is 144.48 hours.

Mai used 49 cups of white paint.

Step-by-step explanation:

Part 1. Every 2 cups of red paint are 1 batch of pink paint. This means to find the number of batches of pink paint Mai made, we need to divide 14/2. 14/2 = 7. This means she made 7 batches of pink paint.

Part 2. For every 2 cups of red paint, there are 7 cups of white paint.

For every 1 cup of red paint, there are 3.5 cups of white paint.

The derivative of tan(cos(t) with respect to t at t= (π/2) is 1.

The derivative of a function of a real variable in mathematics assesses how sensitively the function's value changes in response to changes in its argument. Calculus's core tool is the derivative.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is tan(cos(t)). The derivation will be done as below,

[tex]\dfrac{d}{dx}tan(cos(t))=sec^2(cos(t)\dfrac{d}{dx}(cos(t)\\\dfrac{d}{dx}tan(cos(t))=-sin(t)sec^2(cos(t)\\\dfrac{d}{dx}tan(cos(t))=-sin(\dfrac{\pi}{2} )sec^2(cos\dfrac{\pi}{2})\\\\\dfrac{d}{dx}tan(cos(t))=sec^2(0)\\\dfrac{d}{dx}tan(cos(t))=1[/tex]
