However, each beaker would have the following if there were, say, five beakers: 2.5 units of water are equal to 8.5/5.

Typically, it is expressed in geometric units, which including cubic metres (m3), cubic centimetres (cm3), or cubic feet (ft3), depending on the length unit being used. A formula that is based on an object's shape can be used to determine its volume. The volume of such a rectangular prism, for instance, can be determined by utilizing the formula V = lwh, where l stands for length, w for width, and h for height. A cylinder's volume can be calculated using the formula V = r2h, where r denotes the circle of the base and h the height.

given

We can simply sum the numbers supplied to determine the total volume of water in all the beakers:

1/4 x 6 + 3/4 x 2 + 1/2 + 1 1/4 + 1 1/2 + 1 3/4

= 1.5 + 1.5 + 0.5 + 1.25 + 1.5 + 1.75 (converting mixed values to improper fractions)

= 8.5

8.5 units of water are therefore present in all of the beakers.

Each beaker will have 8.5 divided by the number of beakers if this water is distributed equally among them.

We are unable to provide a precise response since we are unsure of the number of beakers.

Answer:

86.3

Step-by-step explanation:

To find the two possible values of x, we can use the law of sines, which states that:

asinA​=bsinB​=csinC​

where A, B, and C are the angles of the triangle and a, b, and c are the opposite sides.

In this case, we are given A = 50°, a = 10 cm, and b = 9 cm. We can use the law of sines to find sin B:

10sin50°​=9sinB​

sinB=109sin50°​≈0.6904

Now, we can use the inverse sine function to find B:

B=sin−1(0.6904)≈43.7°

However, this is not the only possible value for B. Since the sine function is positive in both quadrant I and quadrant II, there is another angle with the same sine value but in quadrant II. This angle is the supplement of B:

B′=180°−B≈180°−43.7°=136.3°

This means that there are two possible triangles that satisfy the given information: one with B = 43.7° and one with B = 136.3°.

To find x, we need to find C for each triangle using the fact that the sum of angles in a triangle is 180°:

C=180°−A−B≈180°−50°−43.7°=86.3°

C′=180°−A−B′≈180°−50°−136.3°=−6.3°

However, C’ is not a valid angle for a triangle because it is negative. Therefore, we can ignore this possibility and conclude that there is only one possible value for x:

x=C≈86.3°

For a production company of total 24 workers, who works in different shifts. The probability that all 6 workers are selected from the same shift is equals to the 0.0019.

We have a company with faculty working in different shifts. Total number of workers in company = 10 + 8 + 6 = 24

Number of workers work in day shift = 10

Number of workers work in swing shift= 8

Number of workers work in graveyard shift = 6

Now, 6 workers are randomly selected from among 24. That is any of group of 6 can be selected. Number of possible ways to select 6 out of 24 = ²⁴C₆=134,596.

Number of ways to select a group of 6 workers from morning shift = ¹⁰C₆ = 210

Number of ways to select a group of 6 workers from swing shift = ⁸C₆= 56

Number of ways to select a group of 6 workers from graveyard shift = ⁶C₆ = 1

Now, probability to select the group of 6 from morning shift = [tex]\frac{210}{134596}[/tex]

Probability to select the group from morning shift = [tex]\frac{56}{134596}[/tex]

Probability to select the group from graveyard shift=[tex]\frac{1}{134596}[/tex].

Total probability for selecting a group of 6 workers from same shift [tex]= \frac{210}{134596} + \frac{56}{134596} + \frac{1}{134596} [/tex]

There are two real solutions if the radicand is positive.

There is one real solution if the radicand is zero.

There are no real solutions if the radicand is negative.

In mathematics, the radicand refers to the value inside a square root (√) symbol. In the given equations and solutions, we can see that there are square root symbols involved, and we can determine the nature of the solutions based on the sign of the radicand.

For the first equation, y = -16x² + 32x - 10, the solutions for x are given as x = (-32 ± √384) / -32. The radicand in this case is 384. Since 384 is positive, greater than 0, there will be two real solutions for x.

For the second equation, y = 4x² + 12x + 9, the solutions for x are given as x = (-12 ± √0) / 8. The radicand in this case is 0. Since the square root of 0 is 0, there is only one real solution for x in this case.

Therefore, For the third equation, y = 3x² - 5x + 4, the solutions for x are given as x = (5 ± √(-23)) / 6. The radicand in this case is -23. Since the square root of a negative number is not a real number, there are no real solutions for x in this case.

the answer to the problem is that one angle measures 19.1 degrees and its complementary angle measures 70.9 degrees.

How to solve the question?

Let's first define the problem. Complementary angles are two angles whose sum is 90 degrees. Let x be the measure of one of the angles, then the measure of its complementary angle is 90 - x. According to the problem, one angle measures 51.8 degrees less than its complementary angle, so we can write:

x = (90 - x) - 51.8

Simplifying this equation, we get:

2x = 90 - 51.8

2x = 38.2

x = 19.1

Therefore, one angle measures 19.1 degrees and its complementary angle measures 90 - 19.1 = 70.9 degrees.

We can check that these angles are indeed complementary by verifying that their sum is 90 degrees:

19.1 + 70.9 = 90

So the answer to the problem is that one angle measures 19.1 degrees and its complementary angle measures 70.9 degrees.

Okay so Jack started with 50 chocolates, and ended with 2.

The simple way to calculate it would be by realizing that Jack only distributed 48 chocolates. We can find how many times 3 fits into 48 by dividing [tex]48\div3=16[/tex].

Using algebra, we substitute the value we want to find with [tex]x[/tex]. Here what we want to find is the number of friends that were at Jack's party.

We know that he started with 50 chocolates, then distributed [tex]3\times[/tex] the number of friends present (which is [tex]x[/tex]).

We write that down as [tex]50-3x[/tex]

(It's minus because when chocolates are distributed, Jack is taking away from what he has.)

We know that after this, there were only 2 chocolates left, so it's

[tex]\underline{\bold{50-3x=2}}[/tex]

Then we proceed by moving all the numbers to the right until only [tex]x[/tex] is left:

[tex]-3x=2-50[/tex]

[tex]-3x=-48[/tex]

[tex]x=\dfrac{-48}{-3}[/tex]

Conclusion: The number of people that attended the party was 16.

Answer:

500 ≥ 245.50

500 - 245.50 ≥ 0

254.50 ≥ 0

Therefore, she needs to deposit at least $245.50 to avoid a fee.

Step-by-step explanation:

Let x be the least amount of money she needs to deposit to avoid a fee.

The balance in her checking account after writing the check would be (500 - 245.50) = 254.50.

To avoid a fee, the balance must be greater than or equal to 500, so we can write the inequality as:

x + 254.50 ≥ 500

Solving for x, we get:

x ≥ 500 - 254.50

x ≥ 245.50

The volume of the prism with given dimensions in the figure is equal to 612√3 cubic millimeter.

The dimensions of the triangular prism are,

Base of the triangle  'B' = 12mm

let us consider 'h' be the height of the triangle base.

Which intersect base at midpoint

height of the triangle 'h' = √ 12² - 6²

                                        = √108

                                        = 6√3mm

Side length of the prism 'l' = 17mm

Volume of the triangular prism

= ( 1/2 ) × Base × height × length of the side

= ( 1/2 ) × B × h × l

Now , substitute the values we have,

⇒ Volume of the triangular prism  = (1/2) × 12 × 17 × 6√3

⇒ Volume of the triangular prism  = 612√3 cubic millimeter.

The function has a minimum value of -2 that occurrs at x = -1

Given that

g(x) = 2x^2 + 4x

This is a quadratic function with a positive leading coefficient (2), which means that it opens upward and so it has a minimum value.

We can find the vertex of the parabola (the point where it changes direction) by using the formula:

x = -b/2a

where a and b are the coefficients of the quadratic function.

In this case, a = 2 and b = 4, so:

x = -4/(2*2) = -1

To find the corresponding y-value (the minimum value of the function), we substitute x = -1 into the function:

g(-1) = 2(-1)^2 + 4(-1) = -2

(- 2, 16 )

Step-by-step explanation:

y = 8x + 32 → (1)

y = - 8x → (2)

substitute y = 8x + 32 into (2)

8x + 32 = - 8x ( add 8x to both sides )

16x + 32 = 0 ( subtract 32 from both sides )

16x = - 32 ( divide both sides by 16 )

x = - 2

substitute x = - 2 into either of the 2 equations and evaluate for y

substituting into (2)

y = - 8(- 2) = 16

solution is (- 2, 16 )
