Answer:

9 is 8 hours and 10 is 10 hours

Answer:

9.  8 Hours

10. 10 hours

Step-by-step explanation:

48 ÷ 4 = 12  The unit rate is 12 per hour

12x = 96  Divide both sides by 12

x = 8

54 ÷ 6 = 9  The unit rate is 9 per hour

9x = 90  Divide both sides by 9

x = 10

He should order 10 sandwiches of 6 foot long so, as to make sure that everyone will eat 2 pieces.

We need to convert between the units in order to ensure the accuracy and to prevent measurement misinterpretation. For example, we do not measure the pencil's length in kilometres. In this situation, one must convert from kilometres (km) to centimetres (cm) (cm). In most cases, multiplicative conversion factors are used to convert one unit to another of the same quantity. Let's see how to change the length and mass units.

1 Feet = 12 Inches

So, 6 Foot = 72 inches

The Length of sandwich- piece is 4 inch

So, when we convert 6 foot long sandwich into 4 inch,

Then we get number of piece is = 72/4 = 18

From 6 foot long sandwich we get 18 pieces of 4 inch long sub.

Now, Total people who will attend picnic is 40

and each people will eat 2 pieces.

It means total number of piece required = 2 (90) = 180

Mr. eaton required 180 pieces of sandwiches.

Number of sandwiches = 180 / 1.8 = 10

He should order 10 sandwiches of 6 foot long.

y = [tex]\frac{3}{4}[/tex]x + 2

Step-by-step explanation:

To find the slope we will use the slope formula of y2-y1/x2-x1.

Our two y values are 2 and -1.

Our two x values are 0 and 4.

2 - (-1) = 3

0 - 4 = -4

Using percentage formula, Malik can afford the board with the discount only if he has $120 with him

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

To know if Malik can afford the hoverboard, we have to calculate 20% of 150

20% of 150 = 20/100 = x /150

0.2 = x / 150

x = 150 * 0.2

x = 30

Subtracting the discount, the amount will be 150 - 30 = 120

Malik can afford the hoverboard if he has $120 with him.

The radius is increasing fastly at a rate of 2.75 feet per second when it is already 30 feet.

Here, it has been told that the rate of change of the area with respect to the time is = 520 ft²/sec - (i)

This can also be written as = dA/dt (ii)

We need to find the rate of change of radius with respect to the time at 30 feet. This can be written as = dr/dt (iii)

We already know that the area of a circle can be found out using the formula = πr² (iv)

Differentiating equation (ii) with respect to time, we get -

= d(πr² )/dt

= π*(dr²/dt)

= π*(dr²/dr)*(dr/dt)

= π*(2r)*(dr/dt)

= dr/dt = (dA/dt)*(1/ π*2r)

Using the given values, we get -

= (dr/dt) = 520 / π*2*30ft

= (dr/dt) = 2.75 ft/sec

Henceforth, we find that the rate of change of the radius with respect to time at 30 feet is going to be 2.75 ft/sec.

Step-by-step explanation:

BD is perpendicular to AC, forming two right triangles. The hypotenuses are congruent, as is our leg that we will call b. If we use Law of Sines to find our angles a and c (no matter the values), we would find that because b is the same leg in both triangles and the hypotenuses are congruent, angles a and c are congruent, so therefore your missing angle in both triangles is congruent, and using a trig function will find that AD and CD are congruent, making all of both triangles congruent.

Using partial derivatives, we know that in order to optimize profit, the company should produce 7,000 type A solar panels and 8,000 type B solar panels annually.

A function of two or more variables can yield partial derivatives.

Writing the derivative with regard to x while treating all other variables as constants allows one to determine the partial derivative of a function with respect to one variable, let's say x.

The partial derivatives for each of the other

So, for a business making two different types of solar panels, the revenue and cost functions are provided by:

[tex]\begin{aligned}&R(x, y)=4 x+2 y \\&C(x, y)=x^2-4 x y+9 y^2+22 x-114 y-5\end{aligned}[/tex]

If revenue and cost are stated in millions of dollars annually, x represents the thousands of type A solar panels produced and sold annually, and y represents the thousands of type B solar panels produced and sold annually.

By deducting costs from revenues, the profit function is obtained as follows:

[tex]\begin{aligned}&P(x, y)=R(x, y)-C(x, y) \\&P(x, y)=4 x+2 y-\left(x^2-4 x y+9 y^2+22 x-114 y-5\right) \\&P(x, y)=-x^2-9 y^2-18 x+116 y+4 x y+5\end{aligned}[/tex]

The profit function's partial derivatives with regard to x and y are as follows:

[tex]\begin{aligned}&\frac{\partial P}{\partial x}=-2 x+4 y-18 \\&\frac{\partial P}{\partial y}=4 x-18 y+116\end{aligned}[/tex]

When both of these partial derivatives are equal to zero, the profit is maximized:

[tex]\begin{aligned}&0=-2 x+4 y-18 \\&0=4 x-18 y+116\end{aligned}[/tex]

The first equation above is multiplied by two, and the two equations are then added to yield:

[tex]\begin{aligned}&0=-10 y+80 \\&y=8\end{aligned}[/tex]

Inputting into the first equation results in:

[tex]\begin{aligned}&0=-2 x+4(8)-18 \\&2 x=14 \\&x=7\end{aligned}[/tex]

Therefore, using partial derivatives, we know that in order to optimize profit, the company should produce 7,000 type A solar panels and 8,000 type B solar panels annually.

Using mathematical operations we can conclude that the rate of lemons being used in a cup of lemonade is 1/4.

Calculating a value using operands and a math operator is referred to as performing a mathematical "operation."

The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.

In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.

So, we know that:

Lemons required to make 16 cups of lemonade: 4 lemons

The predicted quantity of balls in the first bin is (1/n)n.

Considering that,

There are the same number of balls and containers.

If so, then each container must always contain one ball. The probability of each ball landing in the first bin is (1/n)n.

For instance -

Three balls and three bins should be present. Next to each ball, place an A, B, and C. There are numbers 1, 2, and 3 on the containers. Ball A has a 1/3 chance of landing in bin 1. Although there is a 1/3 probability that ball B will drop in bin 1 and a 1/3 chance that ball C will do the same, both outcomes are possible. Therefore, bin 1 should be equal to 1/3 + 1/3 + 1/3. The rationale behind the projected values of bins 2 and 3 is identical.

According to the same logic, bins 2 and 3 should also have expected values of 1.

How probable is it that the first bin will receive all three balls?

In general, (1/n)n, which equals (1/3)3, or 1/3 x 1/3 x 1/3, equals 1/27.

Therefore, (1/n)n would be the expected number of balls in the first bin.

What is the short definition of cosine law?

According to a trigonometrical rule, the square of a side in a plane triangle is equal to the sum of the squares of the other sides minus twice that amount plus the cosine of the angle between the other two sides.

Given:

Angle AB = 370 miles 24 degrees is A.

Angle BC = 240 miles 37 degrees is B.

Since we have two angles and two sides of a regular triangle, we can apply the cosine law to calculate the distance between points A and C.

Angle B, which is 37 degrees, is the angle opposite side AC.

(AC)^2 =(AB)^2 + (BC)^2 - 2(AB)(BC)cos(B)

solve for AC:

(AC)^2 =(370)^2 + (240)^2 - 2(370)(240)cos(37)

229,48 miles equal AC.

The average rate of change of the function f(x) is found as  -3.75.

The formula for the average rate of change (A(x)) of f(x) over the interval [a,b] is:

A(x) = f(b) - f(a) / b - a

The function being:

f(x) = 20.(1/4)ˣ

Its average rate of change between x = 1 to x = 2 must be determined.

At x = 1

Then;

f(x) = 20.(1/4)¹

f(1) = 5

At x = 2

Then;

f(x) = 20.(1/4)²

f(2) = 1.25

Add these to the formula above to get;

A(x) = f(2) - f(1) / 2 - 1

A(x) = - 3.75

Consequently, the average rate of change of a function f(x) between x = 1 and x = 2 is -3.75.
