Subtract 65 from the product of 20 and 4.​

Answer:

It would be 0.41 ft^3

Step-by-step explanation:

Alright, to start, lets get the volume of the entire cinder block and the holes within it.

1.31 * 0.66 * 0.66 ---> 0.5706...

Next with the holes, they are both 0.33 wide, 0.39 long, and just as tall at 0.66 feet.

0.33 * 0.39 * 0.66 ---> 0.0849...

Since there's two of them: 0.1698...

To finish it, subtract the hole volume from the total volume;

0.5806 - 0.1698 = 0.4108

Rounds to 0.41 ft^3

Answer:

Since this (looks) like a homework assignment/test, I'll give you a hint.

Step-by-step explanation:

A function is where you have a input, that usually involves an equation that you have to replace the unknown with, to get the output.

Don't get it? Well, I didn't either.

What's great about this problem that you don't neccessarily have to know what the definition is.

A function can only output. So if you inputted the number 6, and got the output -3, you can't have another number that also had the output -3, and vice versa. This is my hint for the number 1.

Number 4 is a bit harder, but here's my hint:

Look for a pattern.

Answer:

(x+1)(x+3)(x+5)

Step-by-step explanation:

Answer:

When something is inversely proportional it can be solved by using the equation:

y = k/x

where k is the constant.

So using this we can plug in x and y to find the value of k.

3 = k/4.

Next we isolate k and find that k = 12. Now we use this to find the value of y when x = 8. Plug in x and you get y = 12/8 or y = 3/2 or 1.5.

Another way to solve this is to look at how the value of x changes. When the value of x goes up, the value of y goes down.

In other words, when x is multiplied by some number, y is divided by that number. In this equation we can see that x is multiplied by 2 to go from 4 to 8.

Thus, y must be divided by 2.

Thus, y = 3/2 or 1.5.

Answer:

Step-by-step explanation:

y is inversely proportional to tan x means  

                                                            [tex]y \ \alpha \ \frac{1}{tan x}\\\\y = k \times \frac{1}{tanx}[/tex]

Given y = 2 when x =30° . So we will find k.

                            [tex]y =k \times \frac{1}{tanx } \\\\2 = k \times \frac{1}{tan 30}\\\\k = 2 \times tan 30 = 2 \times \frac{1}{\sqrt{3}} = \frac{2}{\sqrt{3} }[/tex]

Now x is doubled, x = 60°, find y

                         [tex]y = k \times \frac{1}{tanx}\\[/tex]

                            [tex]= \frac{2}{\sqrt{3}} \times \frac{1}{tan 60}\\\\= \frac{2}{\sqrt{3}} \times \sqrt{3}\\\\=2[/tex]

Answer:

The half-life for the zombie population is of 8 years.

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

[tex]N(t) = N(0)(1-r)^t[/tex]

In which N(0) is the initial value and the part [tex](1-r)^t[/tex] is related to the decay.

In this question:

[tex]N(t) = 300(0.5)^{\frac{t}{8}}[/tex]

Thus N(0) = 300, that is, initial population of 300.

What is the half-life for the zombie population?

This is t for which N(t) = 0.5*300 = 150. So

[tex]N(t) = 300(0.5)^{\frac{t}{8}}[/tex]

[tex]150 = 300(0.5)^{\frac{t}{8}}[/tex]

[tex](0.5)^{\frac{t}{8}} = \frac{150}{300}[/tex]

[tex](0.5)^{\frac{t}{8}} = 0.5[/tex]

[tex](0.5)^{\frac{t}{8}} = (0.5)^1[/tex]

Equal exponents, so:

[tex]\frac{t}{8} = 1[/tex]

[tex]t = 8[/tex]

The half-life for the zombie population is of 8 years.

Answer: The customer spends 10 minutes at a booth.

Step-by-step explanation:

Let n= number of booths, [tex]\rho[/tex] = utilization, [tex]\lambda[/tex] = arrival rate, [tex]\mu=[/tex]Service rate

We know that

[tex]\rho=\dfrac{\lambda}{\mu\times n}[/tex]

As per given,

[tex]0.5=\dfrac{15}{\mu\times5}\\\\\Rightarrow\ \mu=\dfrac{15}{5\times0.5}\\\\\Rightarrow\ \mu=6[/tex]

Service rate = 6 customers per hour.

Time taken by each customer = [tex]\frac{1}{\mu}[/tex]

[tex]=\frac{1}{6} \ hours \ or\ \dfrac{60}{6}\ minutes\\\\=10 \ minutes[/tex]

Hence, the customer spends 10 minutes at a booth.

Answer:

Kelly will have to fill the cup 20 times.

Step-by-step explanation:

Volume of the cube:

Rectangular cube, so the volume of the cube is the multiplication of its three dimensions(3.8 inches, 2.5 inches and 7.2 inches).

V = 3.8*2.5*7.2 = 68.4 cubic inches.

If the bucket holds 1,368 cubic inches of water, how many times will Kelly have to fill the cup in order to fill the bucket?

Solved by proportions, using a rule of three.

1 time - 68.4 cubic inches

x times - 1368 cubic inches

Applying cross multiplication:

[tex]68.4x = 1368[/tex]

[tex]x = \frac{1368}{68.4}[/tex]

[tex]x = 20[/tex]

Kelly will have to fill the cup 20 times.

Answer: represents the growth factor which reveals the monthly interest rate.

Step-by-step explanation:

Anthony's account balance can be modeled by the general compound interest formula shown below, where P is the initial amount, r is the annual interest rate, n is the number of times that the interest in the account is compounded per year, and t is the time period.

Consider the given expression.

1250(1+0.06/12)^12t

In the given expression, "1" represents 100% of the money in the account at the start of the month and "" represents the percentage of the account balance that gets added into the account at the end of each month. This is the monthly interest rate and the entire expression,(1+0.06/12t) , is the factor of growth.

Therefore, (1+0.06/12t)represents the growth factor which reveals the monthly interest rate.

Answer:

the height is 599.950

Step-by-step explanation:

The computation of the  horizontal length of the line  is shown below:

The vertical distance is

= 10.20ft - 2.50ft

= 7.70 ft

Now use the pythagoreans theorem to determine the length of the line horizontally i.e presented below;

√horizontal distance^2 + √vertical distance^2 = Slope

√horizontal distance^2 + √7.7^2 = 600

So the height is 599.950

Answer:

Easton entered in 25 shows last year.

Step-by-step explanation:

Given that Easton won best in show in 60% of the shows I have entered, to determine how many show was Easton entered if he won best in show 15 times last year, the following calculation must be performed:

60 = 15

100 = X

(100 x 15) / 60 = X

1,500 / 60 = X

25 = X

Therefore, Easton entered in 25 shows last year.

Answer:

[tex]a:b = 8:3[/tex]

Step-by-step explanation:

To find the ration, we want to get in equation in the form [tex]\frac{a}{b} =\frac{x}{y}[/tex].

We can start by dividing by b on both sides:

3a = 8b

÷b     ÷b

[tex]\frac{3a}{b} = 8[/tex]

Now, we can divide by 3 on both sides to get:

[tex]\frac{a}{b} = \frac{8}{3}[/tex]

We can change the format into a ratio:

[tex]a:b = 8:3[/tex]

ATQ,

= [tex] \dfrac{ - 13}{25} + \dfrac{21}{5} + \frac{ - 21}{18} + x = 5[/tex]

= [tex] \dfrac{ 377}{150} + x = 5[/tex]

= [tex] x = 5 - \dfrac{ 377}{150}[/tex]

= [tex] x = \dfrac{ 373}{150}[/tex]

Answer

=727/150

Step-by-step explanation:

-13/25 + 21/18 + 21/18

= -13 + 105/25 + 21/18

= 92/25 + 21/18

= 1656 + 525/450

= 2181/450   =   727/150

Answer:

x = 12

Step-by-step explanation:

First, we need to find the last interior angle of the triangle. Since we know the exterior angle next to it is 140° and they are supplementary, meaning they form a 180° angle, we can make an equation to solve for the last angle.

∠SRT + 140° = 180°

∠SRT = 40°

Now we know that the last interior angle is 40°. All triangles have a sum of 180°, therefore we can once again set up an equation to solve for x.

3x + 4 + 8x + 4 + 40 = 180

11x + 48 = 180

11x = 132

x = 12

Therefore, x = 12.

Step-by-step explanation:

Recall that

[tex] \cos(x + \pi) = \cos x \cos\pi - \sin x \sin\pi[/tex]

and

[tex] \sin(x - \pi) = \sin x \cos \pi - \cos x \sin \pi[/tex]

But we also know that

[tex] \cos \pi = - 1 \\ \sin \pi = 0 \: \: \: \: [/tex]

so the above relations reduce to

[tex] \cos(x + \pi) = - \cos x \\ \sin(x - \pi) = - \sin x [/tex]

Therefore,

[tex] \cos(x + \pi) - \sin(x - \pi) = - \cos x + \sin x [/tex]
