Answer:

1 is to 4

Step-by-step explanation:

Find lowest common factor of the numbers, which is 4, then divide it into both numbers

The length of the segment RT is the sum of the lengths of RS and ST:

RT = RS + ST

We have:

RT = 56

RS = 2x + 18

ST = 24

So, using those expressions, we find:

RT = RS + ST

56 = 2x + 18 + 24

56 = 2x + 42

Now, to solve this equation, we can apply a sequence of the same operations on both sides of the equation, until we isolate the variable x and find its value:

56 = 2x + 42

56 - 42 = 2x + 42 - 42

14 = 2x

14/2 = 2x/2

7 = x

x = 7

Therefore, x = 7.

Given :

austin is driving to san francisco, suppose that the distance to his destination in miles is a linear function of total driving time. has 67 miles to his destination after 49 minutes of driving . He has 47.5 miles to his destination after 75 minutes of driving .

slope = y2  - y1  / x2 - x1

m = 47.5 - 67 / 75 - 49

= -19.5 / 26

= -3/4

= -0.75

Use the point slope y - y1 = m(x - x1)

y - 67 = -.75 ( x - 49 )

y - 67 = -.75x + 36.75

y = -.75x + 36.75 + 67

y = -.75x + 103.75

x = 85

y = -.75(85) + 103.75

y = -63.75 + 103.75

Answer:

a)  $497.70

b)  392.4 square feet

c)  $1,200

Step-by-step explanation:

A regular octagon has 8 sides of equal length.

Given each side of the octagon measures 9 feet in length, and one side does not have a railing, the total length of the railing is 7 times the length of one side:

\(\textsf{Total length of railing}=\sf 7 \times 9\; ft=63\;ft\)

If the railing sells for $7.90 per foot, the total cost of the railing can be calculated by multiplying the total length by the cost per foot:

\(\textsf{Total cost of railing}=\sf 63\;ft \times \dfrac{\$7.90}{ft}=\$497.70\)

Therefore, the cost of the railing is $497.70.

\(\hrulefill\)

To find the area of the regular octagonal gazebo, given the side length and apothem, we can use the area of a regular polygon formula:

\(\boxed{\begin{minipage}{6cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{n\;s\;a}{2}$\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the length of one side.\\ \phantom{ww}$\bullet$ $a$ is the apothem.\\\end{minipage}}\)

Substitute n = 8, s = 9, and a = 10.9 into the formula and solve for A:

\(\begin{aligned}\textsf{Area of the gazebo}&=\sf \dfrac{8 \times 9\:ft \times10.9\:ft}{2}\\\\&=\sf \dfrac{784.8\;ft^2}{2}\\\\&=\sf 392.4\; \sf ft^2\end{aligned}\)

Therefore, the area of the gazebo is 392.4 square feet.

\(\hrulefill\)

To calculate the cost of the gazebo's flooring if it costs $3 square foot, multiply the area of the gazebo found in part (b) by the cost per square foot:

\(\begin{aligned}\textsf{Total cost of flooring}&=\sf 392.4\; ft^2 \times \dfrac{\$3}{ft^2}\\&=\sf \$1177.2\\&=\sf \$1200\; (nearest\;hundred\;dollars)\end{aligned}\)

Therefore, the cost of the gazebo's flooring to the nearest hundred dollars is $1,200.

a. To find the perimeter of the gazebo, we can use the formula P = 8s, where s is the length of one side. Substituting s = 9, we get:

P = 8s = 8(9) = 72 feet

Since one side is open, we only need to find the cost of railing for 7 sides. Multiplying the perimeter by 7, we get:

Cost = 7P($7.90/foot) = 7(72 feet)($7.90/foot) = $4,939.20

Therefore, the cost of the railing is $4,939.20.

b. To find the area of the gazebo, we can use the formula A = (1/2)ap, where a is the apothem and p is the perimeter. Substituting a = 10.9 and p = 72, we get:

A = (1/2)(10.9)(72) = 394.56 square feet

Therefore, the area of the gazebo is 394.56 square feet.

c. To find the cost of the flooring, we need to multiply the area by the cost per square foot. Substituting A = 394.56 and the cost per square foot as $3, we get:

Cost = A($3/square foot) = 394.56($3/square foot) = $1,183.68

Rounding to the nearest hundred dollars, the cost of the flooring is $1,184. Therefore, the cost of the gazebo's flooring is $1,184.

The required surface area of the climbing toy is 47 square meters.

The climbing toy consists of two cubes, one larger and one smaller. The side lengths of the larger cube are 2 m, so its surface area is:

Surface area of larger cube = 6s^2 = 6(2)^2 = 24 square meters

The smaller cube has a side length of 1 m and it is resting on one entire face on the larger cube. So, the surface area of the smaller cube that is not in contact with the larger cube is:

Surface area of smaller cube = 6s² - 1s² = 6(1)² - 1(1)²= 5 square meters

Therefore, the total surface area of the climbing toy is the sum of the surface area of the two cubes, minus the area of the face where the smaller cube is in contact with the larger cube. The area of this face is the same as the surface area of one face of the smaller cube, which is 1 square meter. Thus, the total surface area is:

Total surface area = 2(Surface area of the larger cube) + Surface area of the smaller cube - Area of the face in contact

Total surface area = 2(24 square meters) + 5 square meters - 1 square meter

Total surface area = 47 square meters

Therefore, the surface area of the climbing toy is 47 square meters.

Answer:

($8.09*s) + ($3.79*c)

$70.77

Step-by-step explanation:

First lets start with the equation and how to get it. Now we know the cost for satin fabric, which is $8.09, and we know that the chosen variable is s. Since it is "per yard", we know we will be multiplying. So now we set it up

$8.09*s

Now lets start with the cotton fabric. We know that the cotton fabric costs $3.79, and the chosen variable is c. Once again, it is per yard so we are multiplying.

$3.79*c

We now have the equation for each fabric so now we can put it together.

$8.09*s + $3.79*c

And that is the final equation. If you want, you can add parenthesis to separate it more. This is optional ONLY since they are already separated by a "+"

9) length of the tree is 22.165 meter

10 )  the length of the steel beams is 3.7464 meters

9 ) Given: The angle is 55.2 °

The length of the shadow is 15.5 meter.

To find : the length of the tree

The by using the formula tan θ = perpendicular / base

tan θ = length of the tree/ shadow

thus the length of the tree = length of shadow × tan θ

= 15.5 × tan 55.2

= 15. 5 × 1.43

= 22.165  meter

Thus the length of the tree is 22.165 meter

10) the angle of inclination = 42 °

The height of the slab is 5.6 meters

Thus the length of the steel beams is :

sin 42 ° = perpendicular / hypotenuse

hypotenuse = perpendicular × 0.669

hypotenuse = 5.6 × 0.669

= 3.7464 meters

Thus the length of the steel beams is 3.7464 meters.

D. 8(y+3) and 24+8y

Step-by-step explanation:

You need to make sure the equations are equal to each other. D is the only one that equals to the other one for infinitive amount of solutions.

8(y+3)=24+8y   divide both sides by 8

y+3 = 3+y this is true, which means it is the answer.

\(A =\left[\begin{array}{ccc}3&0\\-2&1\\\end{array}\right]\) , \(B =\left[\begin{array}{ccc}-2&0\\2&0\\\end{array}\right]\) so that A,B are non-invertible matrices and  A+B is invertible.

An invertible matrix is a matrix in given square matrix A of order n × n is called invertible if there exists another n × n square matrix B such that, AB = BA = Iₙ, where Iₙ is an identity matrix of order n × n.

A non-invertible matrix is a matrix that does not have an inverse, i.e. non-invertible matrices do not satisfy the requisite condition to be invertible.

We have to find non-invertible matrices A,B such that A+B is invertible

so, A =\(\left[\begin{array}{ccc}3&0\\-2&1\\\end{array}\right]\)

and B =\(\left[\begin{array}{ccc}-2&0\\2&0\\\end{array}\right]\)

AB = \(\left[\begin{array}{ccc}-6&0\\6&0\\\end{array}\right]\)  

Therefore A and B matrix are non- invertible

A + B = \(\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right]\)

A square matrix in which every element except the principal diagonal elements is zero is called a Diagonal Matrix.

so, A,B neither is a diagonal matrix and A,B are not scalar multiples of each other.

The number of slides per hour that Ibragim believes he will be able to process w weeks from now is represented by the following calculation: 65 + 2w.

Number is an abstract concept used to describe a quantity or amount. It can refer to a countable quantity of objects, or it can refer to an abstract concept such as size, direction, or position. In mathematics, number is used as a way of measuring and describing a quantity or amount. It is used to represent quantities in equations and formulas, to compare quantities, and to measure and compare distances. Number is also used to represent relationships between different objects, such as in geometry where angles, lines, and points are all represented by numbers.


This equation shows that Ibragim's slides per hour processing speed will increase by 2 for each week that passes. For example, if Ibragim practises for 4 weeks, his slides per hour processing speed will have increased from 65 to 73. This is because 65 + (2 x 4) = 73.

the x-coordinate of the point that is 2/5 of the way from V to W on this line segment is approximately 8.08.

A coordinate is a number or set of numbers that specifies the position of a point in a space. Coordinates are used to describe the position of objects in various mathematical systems, including two-dimensional and three-dimensional Euclidean spaces, as well as non-Euclidean spaces like spherical or hyperbolic geometries.

by the question.

The x-coordinate of the point that is 2/5 of the way from V to W can be found by first determining the x-coordinate of the point that is 2/5 of the way from V to W and then using the formula for finding the x-coordinate of a point on a line given its y-coordinate.

To find the point that is 2/5 of the way from V to W, we need to first find the distance between V and W. Using the distance formula:

d =\(\sqrt{11-(-4)^{2} }\) + (2 - \((-4)^{2}\)) = \(\sqrt{225+36}\)= \(\sqrt{261}\)

Then, the distance between V and the point we're looking for is (2/5) * \(\sqrt{261}\), and the distance between the point we're looking for and W is (3/5) * \(\sqrt{261}\).

To find the x-coordinate of the point we're looking for, we can use the formula:

x = (distance from V to point we're looking for)/ (total distance) * x

coordinate of W + (distance from point we're looking for to W)/(total distance) * x-coordinate of V.

Substituting the values, we found:

x = (2/5 *\(\sqrt{261}\))/\(\sqrt{261}\)) * 11 + (3/5 * \(\sqrt{261}\))/\(\sqrt{261}\)) * (-4) = 8.08
