From the equations below, let's find the value of x.
x=y=2z
xyz=256​

Answers

Answer:

x=8

Step-by-step explanation:

xyz=256​

x=y=2z

Replace y with x and z with x/2

x * (x) *(x/2) =256

x^3 /2 = 256

x^3 = 512

Take the cubed root of each side

(x^3) ^(1/3) = (512) ^ (1/3)

Which runner had the fastest time?

Answers

Answer:

11  1.6

12  Mauricio

Step-by-step explanation:

11.  Take the absolute value of each number to determine which is furthest from zero

|-1.5| and |1.6|

1.5  and 1.6

1.6 is greater than 1.6  so it is further from 0

12.  The fastest time is the smallest time

The ones place all has 7's so look at the tenths place

The smallest number will have the fastest time

Mauricio has a 2 which is the smallest number

Mauricio has the fastest time

Find the value of X and BD

Answers

Answer:

x = 2, BD = 13

Step-by-step explanation:

Given 2 intersecting chords , then

The product of the parts of one chord is equal to the product of the parts of the other chord, that is

4(5x - 1) = 6 × 6 = 36 ( divide both sides by 4 )

5x - 1 = 9 ( add 1 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

BD = 5x - 1 + 4 = 5(2) + 3 = 10 + 3 = 13

Answers

Answer:

D

Step-by-step explanation:

To check this answer, you could obviously graph the points, but without graphing, you can tell the line would be straight because each x value is multiplied by the same number to get the corresponding y value.

3 x 5 = 15, 4 x 5 = 20, etc. This shows linear growth. If each x value were multiplied by twice itself (3 x 6, 4 x 8, and so on), you wouldn't have a straight line because the number that x is multiplied by changes depending on the value of x.

Probability is 0.552, or about 55%

Step-by-step explanation:

first there are 20 marbles in total: odds are 15/20 = 3/4

Then, there are 19 marbles in total : odds are 14/19

So the odds of both of them being blue are: 3/4 * 14/19 = 0.552 (rounded to the thousandths place)

Which quotient is greater than 3? 28 divided by 10, 35 divided by 11, 38 divided by 13 or 40 divided by 14

Answers

Simply divide these all! 28/10 is 2.8, 35/11 is 3.1, 38/13 is 2.9, and 40/14 is 2.8! 35/11 is the only one that is more than 3

The quotient 35 divided by 11 is the only one among the options that is greater than 3.

To determine which quotient is greater than 3, we can calculate the value of each quotient:

28 divided by 10 = 2.8

35 divided by 11 ≈ 3.182

38 divided by 13 ≈ 2.923

40 divided by 14 ≈ 2.857

Comparing these values, we can see that only the quotient 35 divided by 11, which is approximately 3.182, is greater than 3.

Therefore, the quotient 35 divided by 11 is the only one among the options that is greater than 3.

Answers

Answer:

Step-by-step explanation:

f(1) = 160

f(n + 1) = -2 * f(n)

n = 1

f(2) = -2*f(1)

f(2) = -2*160

f(2) = - 320

f(3) = - 2*f(2)

f(3) = -2 * - 320

f(3) = 640

f(4) = -2 * f(3)

f(4) = -2 * 640

f(4) = - 1280

Find the value of each variable. Round your answers to the nearest tenth. (Soh Coh Toa)

Answer:

Step-by-step explanation:

Solve for k:

[tex]tan(40)=\frac{k}{10}\\10(tan(40))=k\\8.4=k[/tex]

Solve for j:

[tex]8.4^2+10^2=j^2\\70.56+100=j^2\\170.56=j^2\\13.1=j[/tex]

Answer:

k = 10 tan (40) = 8.39 (to 2 decimals)

J = 10 / cos(40) = 13.05 (to 2 decimals)

Step-by-step explanation:

It is SOH CAH TOA, or

Sin = Opposite / Hypotenuse

Cos = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Using SOH CAH TOA,

tan(40) = k/10, so k = 10 tan (40) = 8.39 (to 2 decimals)

cos(40) = 10 / j, so J = 10 / cos(40) = 13.05 (to 2 decimals)

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
what price the widgets should be sold for, to the nearest cent, for the company to
make the maximum profit.
y = -x2 + 72x – 458

Answers

Answer:

In order to make the maximum profit, the company should sell each widget at (the currency isn't given, so I'll be assuming USD) $36.

Step-by-step explanation:

The amount of profit y made by the company from selling each widget at x price is modeled by the equation:

[tex]y=-x^2+72x-458[/tex]

Since this is a quadratic with a negative leading coefficient, its maximum will occur at its vertex point. We want to find the price that the widget should be sold to make the maximum profit. So, we want to find the x-coordinate of the vertex. This is given by the formula:

[tex]\displaystyle x=-\frac{b}{2a}[/tex]

In this case, a = -1, b = 72, and c = -458. Substitute and evaluate:

[tex]\displaystyle x=-\frac{72}{2(-1)}=36[/tex]

In order to make the maximum profit, the company should sell each widget at (the currency isn't given, so I'll be assuming USD) $36.

sporting topics or comp.etition please help !!! 5 minutes !!! Pls help Ill brainlest Expand and simplify (3x+4)(2x+3) When writing goals, it is helpful to remember the acronym SMART. Different people associate different words with each of the letters in the SMART acronym, but for the purposes of this problem, SMART means that effective goals are: 1. Specific. A good goal defines exactly what you expect to accomplish. When your goals are specific, the behaviors required to accomplish them are clear. Many people say that they want to recycle to save the environment, but a better goal would be "Place every used bottle or can in a recycling container within five minutes of finishing its contents." 2. Measurable. You can measure the outcomes of a good goal. When you measure how much of a goal you have attained, you get feedback on your work. For example, compare the goal "I want to be skinny" with "I want to lose 10 pounds by the end of the month." How can you measure skinny? But by measuring the pounds you have lost so far, you know exactly how close you are to meeting your goal. 3. Attainable. Good goals are hard to reach, but not impossible. If a goal is too easy, you will not have to work hard to attain it, and your overall performance will not improve. If a goal is too hard, you will be discouraged from attempting to reach it. One way of making sure that goals are attainable is to break larger, difficult goals into smaller, more easily accomplished subgoals. 4. Result-oriented. A good goal contains only one outcome or accomplishment. If you combine two or more outcomes in one goal, it will be difficult to decide where to focus your attention. For example, "To increase produce sales by 3% and to achieve a 5% market share" is a less effective goal than "To increase produce sales by 3%." 5. Time-bound. Good goals specify precisely when you will meet them. Doing so provides you with a deadline for your actions. For example, it is easy to say "I want to be a millionaire." but you are more likely to accomplish that goal if you say "I will have a million dollars in a bank account by January 1, 2020." Using your knowledge of SMART goals, select the best goal. After the new product is released, I will hire some new salespeople. a.
