Answer:

141.6925 [tex]ft^{2}[/tex]

Step-by-step explanation:

Area of rectangle  = LW

A = 29 x 19 = 551 [tex]ft^{2}[/tex]

Semicircle = [tex]\frac{\pi r^{2} }{2}[/tex]

[tex]\pi[/tex] = 3.14

r = 19/2 = 9.5

[tex]\frac{(3.14)(9.5^{2}) }{2}[/tex]

(9.5)^2 = 90.25

3.14 x 90.25 = 283.385

283.385/2 = 141.6925 [tex]ft^{2}[/tex]

To find the y-coordinate of the solution, we can substitute in this value for y and round it to the nearest tenth: y = -2.2

system of coordinates, Arrangement of reference lines or curves for locating points in space The Cartesian (named for René Descartes) system is the most popular one in two dimensions.

To solve for y in the equation 5x + 2y = 21, we can start by isolating y on one side of the equation. To do this, we can subtract 5x from both sides of the equation:

5x + 2y = 21

5x - 5x + 2y = 21 - 5x

2y = 21 - 5x

To solve for y, we can then divide both sides of the equation by 2:

2y = 21 - 5x

y = (21 - 5x) / 2

To solve for y in the equation -21 + 6y = -34, we can start by isolating y on one side of the equation. To do this, we can add 21 to both sides of the equation:

-21 + 6y = -34

-21 + 21 + 6y = -34 + 21

6y = -13

To solve for y, we can then divide both sides of the equation by 6:

6y = -13

y = -13/6

y = -2.1666666666666665

To find the y-coordinate of the solution, we can substitute in this value for y and round it to the nearest tenth:

y = -2.2

So, the y-coordinate of the solution is -2.2.

Answer:

no, it's not correct

Step-by-step explanation:

volume or the cube = L³

so if we doubled the side lengths

They would be 2L

then the volume= (2L)³ = 8L³

so that would make the volume 8 times the first value not double

Answer:

Step-by-step explanation:

We have, C(x) = 0.005x3 – 0.02x2 + 30x + 5000

Clearly, the marginal cost, MC (x) = \(\frac{d}{d x}\)C(x)

= \(\frac{d}{d x}\)(0.005x3 – 0.02x2 + 30x + 500)

= 0.005 × 3x2 – 0.02 × 2x + 30 + 0

= 0.015x2 – 0.04x + 30

Now, marginal cost when 3 units arei produced

MC(3)= 0.015(9) – 0.04(3) + 30

= 0135 – 0.12 + 30= 30.015

a=68

e=68

c=112

Explanation:

Each line is equal to 180 degrees so 180-68 is 112 f and a should be the same degree because of the way the line is slanted. E and c will be the inverse of d and 68.

We can conclude from answering the above question that the first two patterns of the matrix  form a sequence in the third from top with the numbers 4-2-6.

A matrix is a set of numbers arranged in rows and columns. learns about the elements and dimensions of matrices and introduces them for the first time. A rectangular grid of numbers in rows and columns is known as a matrix. Matrix A, as an illustration, has two rows and three columns. Its single row and 1 n row matrix order are the reasons behind its name. A = [1 2 4 5] is a row matrix of order 1 by 4, for instance. P = [-4 -21 -17] of order 1-by-cubic is another illustration of a row matrix.

The total cost for your fun day out is $23.82.

In mathematics →

Given is that you decided to go snowboarding for the day and you have to figure out your budget. Tickets are $75.00 per day and there is a 5% convenience charge when you order your ticket. You also have to pay for a bus ticket that is $12 for the day. You mom gives you a 15% off coupon that applies to the lift ticket only.

Assume that the total cost for your fun day out is ${x}. Then, we can write the equation as -

{x} = 15% of (75 + {5% of 75}) + 12

{x} = 15% of (75 + {5/100 x 75}) + 12

{x} = 15% of (75 + {1/20 x 75}) + 12

{x} = (15/100) x (75 + 75/20) + 12

{x} = (3/20 x 78.75) + 12

{x} = 11.82 + 12

{x} = 23.82

Therefore, the total cost for your fun day out is $23.82.

∠EFH and ∠ACD are angles of alternate exterior angles in the figure as  alternate external angles are those that are generated on the outer side of the parallel lines .

When two straight lines connect at a 90° angle or are perpendicular to one another, an angle is formed. The symbol denotes a right angle. In the picture up above, many right angle formations are visible. Shapes include the correct angles. Triangles classified as right triangles have one of their internal angles at a 90 degree right angle. The three interior angles of a triangle add up to 180 degrees, so the three interior angles of a right triangle must always add up to 90 degrees because one of them is always 90 degrees.

given

The pair of angles known as alternate external angles are those that are generated on the outer side of the parallel lines but on the transverse side.

sum up to 180 degrees, you can calculate the size of the inner angle adjacent to it if you know the size of the outer angle (since together they are the angle on a straight line). The internal angles at the other two vertices are added to create the outer angle of a triangle.

To simplify 3 ratios, divide each part of the ratio with the same amount and keep diving numbers in the ratio until they are as small as possible but they remain as whole numbers.

To simplify or reduce a fraction, first, we need to find a common factor between the ratio numbers. When we have multiple ratio numbers, we must find a common factor between all of them.

The greatest factor between all the ratio numbers (greatest common factor) will be utilised to divide or reduce the ratios down to their lowest form.

For example reduce the ratio 350: 250: 125

The first step is to determine a common factor between all of the ratio numbers. In this example, we can see that all of the numbers end in either 5 or 0. This means that each number should have 5 as a factor.

If numbers are large and we are not sure of the greatest common factor between them all, we can reduce by a common factor and then reduce again.

Now divide each number by 5 and see what we get.

350/5: 225/5: 125/5

70: 45: 25

When we divide each one by 5 again, we can see that each number again ends in 5 or 0 which means that 5 is still a factor of each number.

Now divide each number by 5 again and get a final ratio of 14: 9: 5.

70/5: 45/5: 25/5

14: 9: 5

In a course of 12 weeks, Perry will be able to play a total of 25 pieces of the piano Leon.

A total of 18 pieces of piano are learnt by Perry in a course of 9 weeks.

By using simple algebra, we can find the number of pieces that will be played by Perry in one week,

So, we can write, The learing speed,

Number of piano pieces learnt = Weeks

19 pieces = 9 weeks

Learning speed = 19/9 Pieces per week

So, the number of pieces learnt in 12 weeks is,

Number of pieces learnt = 19/9 x 12

Number of pieces learnt = 25.22

Number of pieces learnt = 25

So, Perry will be able to play 25 pieces.
