Answer:

The lake's shape is a cylinder. The volume of a cylinder is given as: V=πhr^2 where r equals the radius, and h the depth. Therefre, the volume of the lake is:

V=πhr^2

V=π(20ft)(32,5ft)^2

V=66.364,1875‬ ft^3.

Given that 66.364,1875‬ ft^3 equals 496.44 gallons, we can say that 496.44 gallons of water is required to fill the lake.

Answer: 5000 cm is greater than 5 m

Step-by-step explanation:

When you convert 5000 cm to m 5000 cm is equal to 50 m so 5000 cm is greater than 5 m

Answer:

D

Step-by-step explanation:

Answer D is correct.  The indicated line segments are both radii of the circle and are thus of the same length (and thus, congruent).

Answer: D. RE

Step-by-step explanation:

In the given picture , we have a circle with center R having two chords as WF and MU.

The two chords WF and MU have equal length.

i.e. [tex]WF=MU=11.2[/tex]

We know that the equal chords of a circle are equidistant from the center.

⇒ [tex]\overline{RA}=\overline{RE}[/tex]

Answer:

The time at which the ball will reach its maximum height is t= 3 seconds.

Step-by-step explanation:

To find the the time at which the ball will reach its maximum height,  we need to solve the model given - 3x2 + 18x +7

since h(t) is the height given we can re-write the equation as:

h(t)= -3(t)² + 18t +7

Differentiating the above equation

[tex]\frac{dt}{dh} = -6t + 18[/tex]

When the ball is at maximum height [tex]\frac{dt}{dh}=0[/tex]

0=-6t+18

-18 = -6t

=> t= -18/-6

=> t= 3

the time at which the ball will reach its maximum height is t= 3 seconds.

We can find the maximum height by putting value of t in equation:

h(3) = -3(3)²+ 18(3) +7

h(3)= -27 + 54 + 7

h(3)= 34 ft

Step-by-step explanation:

20.00 for each pair of shoes

Cost of one pair of shoes is $4.0625 (Approx.)

Cost of 25 pair gloves and 15 pair shoes = $374.25

Cost of 14 pair gloves and 4 pair shoes = $117.49

Cost of one pair of shoes

Assume;

Cost of one pair of gloves = a

Cost of one pair of shoes = b

So,

25a + 15b = 374.25 ......... eq1

14a + 4b = 117.49 ......... eq2

eq2 × 3.75

52.5b + 15b = 440.5875 ........ eq3

Eq3 - eq1

a = 2.41

So,

14a + 4b = 117.49

b = $4.0625

Cost of one pair of shoes = $4.0625 (Approx.)

I hope this helps you!!

The possible values of the lengths and widths of the rectangle are (16, 1) and (8, 2).

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know the area of a rectangle is (length×width).

Given, The area of the rectangle is 16 square units.

Therefore, (length×width) = 16.

So, the possible dimensions are multiples of 16 which is,

Answer: C 18000

Step-by-step explanation:

Julie contributes $12,000 to her 401k and her employer matches 50% of this amount, contributing an additional $6,000. Thus, the total balance in Julie's 401k after the employer's contribution is added is $18,000.

The question involves calculating the total balance in Julie's 401k account after her employer's contribution. Julie contributes $12,000 to her 401k, and her employer offers a 50% match on contributions. To find the total balance, first calculate the employer's contribution, which is 50% of Julie's contribution, so $12,000 x 0.5 = $6,000.

Adding the employer's contribution to Julie's contribution gives us the total balance in the 401k account. Therefore, $12,000 (Julie's contribution) + $6,000 (employer's match) = $18,000.

To estimate the difference between 10 1/9 and 5 14/15, we round them to the nearest whole numbers, 10 and 6, respectively, and then subtract to get an estimated difference of 4.

To estimate the difference between the two numbers 10 1/9 and 5 14/15, we can round them to easier numbers to subtract. 10 1/9 is approximately 10, and 5 14/15 is close to 6 because 14/15 is almost a whole number. Now, we can simply subtract 6 from 10.

10 - 6 = 4

So, the estimated difference between 10 1/9 and 5 14/15 is about 4.

Simplifying

3x2 + 5x + -7x + 3 + -5x2 + 2 = 0

Reorder the terms:

3 + 2 + 5x + -7x + 3x2 + -5x2 = 0

Combine like terms: 3 + 2 = 5

5 + 5x + -7x + 3x2 + -5x2 = 0

Combine like terms: 5x + -7x = -2x

5 + -2x + 3x2 + -5x2 = 0

Combine like terms: 3x2 + -5x2 = -2x2

5 + -2x + -2x2 = 0

Solving

5 + -2x + -2x2 = 0

Solving for variable 'x'.

Begin completing the square. Divide all terms by

-2 the coefficient of the squared term:

Divide each side by '-2'.

-2.5 + x + x2 = 0

Move the constant term to the right:

Add '2.5' to each side of the equation.

-2.5 + x + 2.5 + x2 = 0 + 2.5

Reorder the terms:

-2.5 + 2.5 + x + x2 = 0 + 2.5

Combine like terms: -2.5 + 2.5 = 0.0

0.0 + x + x2 = 0 + 2.5

x + x2 = 0 + 2.5

Combine like terms: 0 + 2.5 = 2.5

x + x2 = 2.5

The x term is x. Take half its coefficient (0.5).

Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.

+ 0.25 + x2 = 2.5 + 0.25

Combine like terms: + 0.25 = 1.25

1.25 + x2 = 2.5 + 0.25

Combine like terms: 2.5 + 0.25 = 2.75

1.25 + x2 = 2.75

Factor a perfect square on the left side:

(x + 0.5)(x + 0.5) = 2.75

[tex]l=\frac{A}{w}[/tex]

You know that the floor of Paul's and Matthew's rectangular bedroom has an area of 132 square feet and its width is 11 feet. Then, you can substitute these values into [tex]l=\frac{A}{w}[/tex] to calculated the lenght. Therefore, the result is:

[tex]l=\frac{132ft^2}{11ft}[/tex]

Answer:

Cone diameter = 18 m therefore radius = 9 m

Lateral Area = PI * radius * slant height

Lateral Area = 3.14 * 9 * 15 = 423.90 square meters

Step-by-step explanation:

Final answer:

The lateral surface area of a cone with a diameter of 18 meters and a slant height of 15 meters is approximately 423.9 square meters, calculated using the formula LSA = πrl with π approximated as 3.14.

Explanation:

The student is asking about finding the lateral surface area of a cone with a given diameter and slant height, where the diameter is 18 meters and the slant height is 15 meters. To find the lateral surface area (LSA) of a cone, the formula LSA = πrl can be used, where 'r' is the radius of the base and 'l' is the slant height of the cone. Since the diameter is 18 meters, the radius is half of that, which is 9 meters. Using 3.14 as the approximation for π (pi), we can calculate the lateral surface area.

The calculation would be as follows:

Find the radius (r): Diameter / 2 = 18m / 2 = 9m.

Use the formula LSA = πrl: LSA = 3.14 * 9m * 15m.

Calculate the LSA: LSA = 3.14 * 135m².

LSA = 423.9m², which is the lateral surface area of the cone.

Therefore, 423.9 square meters is the closest approximation to the lateral surface area of the given cone.

1350 different selections.

Step-by-step explanation:

They have 3 choices for the bands. 15 choices for the stones. and 30 choices for the symbols. Multiply 3 x 15 x 30 for the total number of selections.

Answer: There are 1,350 different ring selections.

Step-by-step explanation:

Given : The number of metals used for rings (gold, silver, or white gold ) =3

The number of stones they have = 15

The number of activity symbols = 30

By using the fundamental principal of counting , we have the total number of different ring selections as :-
