( Your question asks for m^2 discharge......I think you need m^3 discharge per minute)

Find the volume of a cylinder that is 8 meters long with radius of 8cm ( .08 m)

area = pi r^2 = pi (.08)^2 = .0201 m^2

    area * 8 m   = volume PER SECOND

        volume PER SECOND  *  60 = volume per minute

                 .0201   * 8 * 60 = 9.65 m^3 / min  discharge

The diver is 60 feet below the surface then moves up 40 feet.

Answer:

∠1 = 36°

∠2 = 72°

∠3 = 72°

∠4 = 72°

∠5 = 36°

Step-by-step explanation:

The angles of rhombus are ∠1 = 36°, ∠2 = 72°, ∠3 = 72°, ∠4 = 72°,       ∠5 = 36°.

A rhombus is a quadrilateral with four equal sides and opposite equal angles. It has two diagonals that bisect each other at right angles. It also has opposite sides parallel and the sum of all the four interior angles is 360 degrees.

For the given situation,

From the diagram of rhombus,

The angle is 72°.

In rhombus,

Opposite angles are equal.

So, \(\angle2 = \angle3 = \angle4\) are equal to \(\angle72\).

Diagonals bisect the angles and the sum of two adjacent angles is equal to 180 degrees.

⇒ \(\angle D + \angle E = 180\)

Here, \(\angle D = \angle 72 + \angle 72\)

⇒ \(\angle D = \angle 144\)

Thus, \(\angle E = \angle 180 -\angle 144\)

⇒ \(\angle 1 = \angle 36\)

we know that, \(\angle E = \angle G\)

⇒ \(\angle 5 = \angle 36\)

Hence we can conclude that the angles of rhombus are ∠1 = 36°, ∠2 = 72°, ∠3 = 72°, ∠4 = 72°, ∠5 = 36°.

Answer:

14.1

Step-by-step explanation:

You add all of your numbers up, and then you divide by how many numbers you have.

Answer:

The graph y = 18x2 + mx + 2= 12

So the answer is 12

The value of m does the graph of y = 18 x² + m x + 2 have exactly one x-intercept is 12.

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

We have Equation.

y = 18 x² + m x + 2

Now, to find exactly one intercept we will use Discriminant Method as

D = m² - 4 x 18 x 2 = 0

m² - 144 = 0

m² = 144

m = -12 or m = 12

Thus, the required value of m is 12.

Answer:

Let's take the angle LEFT to p to be "x".

80+30+x = 180

110+x = 180

x = 70

Finding p:

90+70+p = 180     (REASON: linear pair)

160+p = 180

p = 20

THEREFORE, THE VALUE OF 'p' IS 20°

The work required to raise the bucket and the remaining grain to the top is approximately 2,400 Joules.

To calculate the work required, we need to consider two components: the work required to lift the bucket and the work required to lift the remaining grain.

The work required to lift the bucket can be calculated using the formula:

Work_bucket = force_bucket * distance,

where force_bucket is the weight of the bucket and distance is the height it is lifted.

The weight of the bucket can be calculated as the product of its mass and the acceleration due to gravity:

Weight_bucket = mass_bucket * g,

where mass_bucket is the mass of the bucket (2 kg) and g is the acceleration due to gravity (9.8 m/s^2).

Substituting the values, we have:

Weight_bucket = 2 kg * 9.8 m/s^2 = 19.6 N.

The distance the bucket is lifted is 20 m.

Therefore, the work required to lift the bucket is:

Work_bucket = 19.6 N * 20 m = 392 J.

Next, we calculate the work required to lift the remaining grain. The weight of the remaining grain can be calculated in a similar way:

Weight_grain = mass_grain * g,

where mass_grain is the mass of the remaining grain (12 kg) and g is the acceleration due to gravity (9.8 m/s^2).

Substituting the values, we have:

Weight_grain = 12 kg * 9.8 m/s^2 = 117.6 N.

The distance the remaining grain is lifted is 10 m.

Therefore, the work required to lift the remaining grain is:

Work_grain = 117.6 N * 10 m = 1176 J.

To find the total work required, we add the work required to lift the bucket and the work required to lift the remaining grain:

Total work = Work_bucket + Work_grain = 392 J + 1176 J = 1568 J.

Therefore, the total work required to raise the bucket and the remaining grain to the top is approximately 2,400 Joules.

Answer:

B

Step-by-step explanation:

We know that it costs 37 cents to mail a letter that weighs 1 oz or less. This would mean that for x ≤ 1, P(x) should equal 37. Already, we can eliminate A and D.

We also know that it costs an additional 26 cents for at most another ounce added to the original 1 ounce. This means that for 1 < x ≤ 2, P(x) = 26 + 37 = 63. This is shown by B.

Thus, the answer is B.

The final exponential expression in fractional form for "the eighth root of fifty-seven to the sixth degree" is 57^(3/4).

To express the given description as a symbolic expression and then convert it into an exponential expression in fractional form, we'll follow these steps:

Step 1: Symbolic Expression

The description states "the eighth root of fifty-seven to the sixth degree." Let's denote this as √[57]^(1/8)^6.

Step 2: Removing Radical

To eliminate the radical (√), we can rewrite it as a fractional exponent. The numerator of the fractional exponent corresponds to the power (6) applied to the base, and the denominator corresponds to the index of the root (8).

So, the expression becomes (57^(1/8))^6.

Step 3: Simplifying Exponents

To simplify the exponent, we multiply the powers:

(57^((1/8)*6))

Simplifying further:

(57^(6/8))

Step 4: Fractional Form

The exponent 6/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(57^(3/4))

Therefore, the final exponential expression in fractional form for "the eighth root of fifty-seven to the sixth degree" is 57^(3/4).

This means that we raise 57 to the power of 3/4 to represent the original description. The fraction 3/4 indicates taking the eighth root of 57 and then raising it to the sixth power.

Approximately 13.7% of the cost per gallon will go towards paying the combined state and federal fuels tax.

The mathematical equation that represents the percentage of the cost per gallon that will go towards paying the combined state and federal fuels tax is given by:

(Combined state and federal fuels tax / Cost per gallon of gasoline) * 100

To calculate the percentage, we divide the combined state and federal fuels tax by the cost per gallon of gasoline and then multiply by 100 to convert it to a percentage.

For example, if the cost per gallon of gasoline is $2.92 and the combined state and federal fuels tax is $0.40, we can substitute these values into the equation:

(0.40 / 2.92) * 100 = 13.7%

Answer:

9 inches.

Step-by-step explanation:

To find out what d (distance) is, make a proportion of the values you know and d. This would be 15/67.5 = 2/d.

¹⁵/₆₇.₅ = 2/d

Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by d.

d * (¹⁵/₆₇.₅) = 2

Expand 15/67.5   by multiplying both numerator and the denominator by 10.

d * (¹⁵⁰/₆₇₅) = 2

Reduce the fraction ¹⁵⁰/₆₇₅  to lowest terms by extracting and canceling out 75.

d * (²/₉) = 2

Multiply both sides by ⁹/₂, the reciprocal of ²/₉.

d = (2 * 9)/2

Cancel out 2 and 2.

d = 9

The distance between the SLMS from the tide pools on the map is 9 inches.

The measure of the segment xy of the given right angle triangle is; 36 units

This question can be best understood if the trigonometric ratios are briefly highlighted since it has been used in the question. Cos f is given as 4/9. We know that the cos of an angle is derived as the adjacent divided by the hypotenuse. In other words, the cosine of angle f is given as;

Cos f = Adjacent / Hypotenuse

Thus;

Cos f = 4/9

From the triangle shown in the attachment, the adjacent is XW while the hypotenuse is XY. Hence, the adjacent is 16 units and the hypotenuse is unknown. Since the measurements given in the question are a ratio of the original dimensions, the relationship can be expressed as follows;

4/9 = 16/XY

Where XY is the unknown side

By cross multiplication, you now arrive at,

4XY = 9 * 16

XY = 144/4

XY = 36

Therefore, XY measures 36 units
