Answer:

[tex]x=\sqrt[3]{\frac{500}{27}}[/tex]≈ [tex]2.64566842[/tex]

Step-by-step explanation:

[tex]\frac{27x^{3}}{4}=125\\27x^{3}=125*4\\27x^{3}=500\\x^{3}=\frac{500}{27}\\x=\sqrt[3]{\frac{500}{27}}[/tex]

An approximation in decimal form would be as follows:

[tex]x=\sqrt[3]{\frac{500}{27}}[/tex]≈ [tex]2.64566842[/tex]

First, let's define a few varibles.

x = # of miles

y = # of days

z = total cost

Now, let's create our expression

z = $23.95y + $0.33x

Let's plug the numbers from our problem into our equation.

$150 = $23.95(2) + $0.33x

Simplify the right side

$150 = $47.9 + $0.33x

Subtract $47.9 from both sides

$102.1 = $0.33x

Divide both sides by $0.33

309 miles = x

Note, I rounded my answer down to the nearest whole number.

Answer:

6 1/4 cups of flour

Step-by-step explanation:

24/2 = 12

2.5/2 = 1.25

12 x 5 = 60

1.25 x 5 = 6.25 cups

For every 24 cookies Markes needs 2.5 cups of flour. So, for 12 cookies he needs half of that which is 1.25 cups. 12 is a fifth of 60, so we multiply 1.25 by 5 which gives us 6.25 cups of flour. :D

Step-by-step explanation:

A spreadsheet is made for this sort of computation. Copy the data to a spreadsheet. Use the "text to columns" feature to separate the data from the dates, and to put the A and B data in different columns.

Then use the spreadsheet built-in covariance and correlation functions to find the values of interest.

In the attachment, we have hidden the middle 50 rows of data to make it easier to select the range of data required for the functions we're using. (In many spreadsheets, you can name a range, so you only need to refer to it by name.)

The formulas we used are ...

  in D2: =COVAR(B2:B61,C2:C61)

  in D3: =CORREL(B2:B61,C2:C61)

Additional comment

Graphing calculators and spreadsheets are essential technology tools. While it can take a bit of study to learn all of the features in depth, you can usually learn enough in a few minutes to be able to make use of these tools to solve many problems. In most cases, videos are available.

The Go.ogle Sheets application works in a browser and is free. That's what was used here. Other free office-type applications (word processor, spreadsheet, and so on) are also available for download to computer, tablet, or phone. (I find it tedious to use these apps on a phone.)

Answer:

- 376

Step-by-step explanation:

8u = 8(- 8i + 3j ) ← multiply each element by 8

    = - 64i +24j

Then

(- 64i + 24j ) • (4i - 5j )

= (- 64 × 4) + (24 × - 5)

= -256 + (- 120)

= - 256 - 120

= - 376

What is the probability of drawing a red card or a queen from a standard deck of 52 cards?

7 over 13

15 over 26

1 half

1 over 26

The probability for red card or queen is given as 15/26. The correct option is (B).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total number of red cards in the deck is 26.

And, the number of queens in the deck is 4.

Now, the probability of getting red card is given as,

P(red cards) = Number of red cards ÷ Total number of cards

⇒ P(red cards) = 26/52 = 1/2.

Similarly, the probability of queen is,

P(queen) = 4/52 = 1/13

Thus, the probability of drawing a queen or red card is given as,

P(red card or queen) = P(red card) + P(queen)

⇒ P(red card or queen) = 1/2 + 1/13 = 15/26.

Hence, the probability of drawing a red card or a queen from a standard deck of 52 cards is 15/26.

Hello!

The perimeter is sum of all sides of a figure. In this figure, we have unknown sides. To find the unknown sides, we have to use the sides that we know. By adding and subtracting numbers, you can find the other sides. See the image below, to see how I did it.

The slope is -2. In context to this problem, the candle will burn away 2cm of its length every hour.

The slope of the equation, -2, means that the height of the candle reduces at a rate of 2 cm per hour.

Given the linear equation of the height of a candle that has been burning as: [tex]h = 28 - 2t[/tex].

This implies that:

28 in the equation represents the initial height of the candle = 28 cm.

-2 in the equation is slope, which is the rate of change at which the candle burns, meaning the height of the candle reduces by 2 cm every hour.

Therefore, the slope of the equation can be interpreted in the context of the problem as:

for every hour that passes, the height of the candle reduces by 2 cm.

Answer:

The water level would rise by [tex]5\; \rm cm[/tex].

Step-by-step explanation:

Assume that the initial water level is [tex]h\; \rm cm[/tex].

Before the cube was placed in the tank, the volume of the water was the same as the volume of a rectangular prism with a length of [tex]160\; \rm cm[/tex], a height of [tex]80\; \rm cm[/tex], and a height of [tex]h\; \rm cm[/tex]:

[tex]\begin{aligned} & 160\; {\rm cm} \times 80\; {\rm cm} \times h\; {\rm cm} \\ =\; & (80 \times 160) \, h \; \rm cm^{3} \end{aligned}[/tex].

Let the rise in the water level in the tank be [tex]x\; \rm cm[/tex]. The new water level would be [tex](x + h)\; \rm cm[/tex].

The volume of the water and the submerged cube, combined, would be the same as that of a rectangular prism with a length of [tex]160\; \rm cm[/tex], a width of [tex]\rm 80\; \rm cm[/tex], and a height of [tex](x + h)\; \rm cm[/tex]:

[tex]\begin{aligned} & 160\; {\rm cm} \times 80\; {\rm cm} \times (x + h)\; {\rm cm} \\ =\; & (80 \times 160) \, (x + h) \; \rm cm^{3} \end{aligned}[/tex].

In other words:

Therefore, the volume of the submerged cube could be expressed as:

[tex]\begin{aligned} & (80 \times 160) \, (x + h) \; {\rm cm^{3}} - (80 \times 160) \, h \; \rm cm^{3} \\ =\; &(80 \times 160)\, x\; {\rm cm^{3}}\end{aligned}[/tex].

On the other hand, the volume of the cube could be expressed as:

[tex](40\; \rm cm)^{3} = 64000\; \rm cm^{3}[/tex].

Equate these two expressions for the volume of the cube and solve for [tex]x[/tex], the rise in the water level in the tank:

[tex](80 \times 160)\, x = 64000[/tex].

[tex]x = 5[/tex].

In other words, the rise in the water level in this tank would be [tex]5\; \rm cm[/tex].

Answer:

See Below.

Step-by-step explanation:

By definition, if two functions, f and g, are inverses, then:

[tex]\displaystyle f(g(x)) = g(f(x)) = x[/tex]

We are given the two functions:

[tex]\displaystyle g(x) = \sqrt{x + 8} -4 \text{ and } f(x) = x^2 + 8x + 8[/tex]

Find f(g(x)) and g(f(x)):

[tex]\displaystyle \begin{aligned} f(g(x)) &= (\sqrt{x + 8} -4)^2 + 8(\sqrt{ x+ 8}-4) + 8 \\ \\ &= ((x+8) -8\sqrt{x + 8} +16) + 8\sqrt{x + 8} - 32 + 8 \\ \\ &= x + (-8\sqrt{x+8} + 8\sqrt{x + 8}) +(16 - 32 + 8 + 8) \\ \\ &= x \stackrel{\checkmark}{=} x\end{aligned}[/tex]

And:

[tex]\displaystyle \begin{aligned}g(f(x)) &= \sqrt{(x^2 + 8x + 8) + 8} - 4 \\ \\ &= \sqrt{x^2 + 8x+16 } - 4 \\ \\ &=\sqrt{(x+ 4)^2} - 4 \\ \\ &= (x +4) - 4 \\ \\ &= x \stackrel{\checkmark}{=} x \end{aligned}[/tex]

Hence, f and g are indeed inverses of each other.
