Given that;
To build the bookshelf, Tim want the three horizontal length of each length 3[tex]\frac{2}{3}[/tex] feet and two vertical length with each length 2[tex]\frac{5}{8}[/tex] feet.
Now, Find the total lengths for the amount of wood as;
The length of each horizontal = 3[tex]\frac{2}{3}[/tex] feet
And, The vertical length = 2[tex]\frac{5}{8}[/tex] feet
So, Total horizontal length = 3 × 3[tex]\frac{2}{3}[/tex]
= 3 x 11/3
= 11 feet.
And, Vertical length = 2 × 2[tex]\frac{5}{8}[/tex] feet.
= 2 × 21/8
= 5[tex]\frac{1}{4}[/tex] feet
Thus, Total length of wood = 11 + 21/4 feet
= ( 44 + 21 ) / 4
= 69 / 4 feet
= 17[tex]\frac{1}{4}[/tex] feet
Therefore,
The total amount of wood to build the shelves will be;
⇒ 17[tex]\frac{1}{4}[/tex] feet

Scale factor from smaller to larger of THIS triangle
The scale factor in the image depicting a similar triangle is solved to be
1.4When are triangles said to be similar?The term similar triangles as used in geometry means that the respective sides of the triangles are proportional and the corresponding angles of the triangles are congruent
Hence when the size of the triangles are in equal proportions and the size of the angles are equal then the triangles are said to be similar triangles
Examining the figure shows the scale factor is sought as follows
using side 28
let the scale factor form smaller to larger be k
k = length of larger side / length of smaller side
k = 28 / (28 - 8)
k = 28 / 20
k =1.4

Determine the graph that represents a function. On a coordinate plane, a circle is shown that crosses the x-axis at (negative 5, 0), the y-axis at (0, 5), the x-axis at (5, 0), and the y-axis at (0, negative 5). On a coordinate plane, a parabola opens to the left. It crosses the y-axis at (0, 3) and (0, negative 3), and the x-axis at (9, 0). On a coordinate plane, a straight line with a positive slope crosses the y-axis at (0, negative 2) and the x-axis at (1.2, 0).
Answer: The graph that represents a function is the parabola that opens to the left.
This can be determined by the following characteristics of the graph:
It is a parabola because it opens to the left and has a vertex on the y-axis.
It crosses the y-axis at (0, 3) and (0, negative 3), which means that it is symmetric about the y-axis, and also it crosses the x-axis at (9, 0) which means that it is a function.
A circle is not a function because, for any value of x, there are two different values of y that can be plotted on the graph (i.e. the point (5,0) and (-5,0) produce two different y values)
A straight line with a positive slope is not a function because, for any value of x, there is only one value of y that can be plotted on the graph.
So the parabola is the graph that represents a function.

The questions below can be solved using the relation between angular size, physical size and distance. For the questions below, provide a complete solution with explanation.
1. Find the Sun's diameter. The sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. What is the sun's approximate physical diameter? Compare your
answer to the actual value of 1 390 000 km.
2. Find a Star's Diameter. The supergiant star Betelgeuse (in the constellation Orion) has a measured angular diameter of 0.040 arcsecond from Earth and a distance from Earth of 720 light-years. What is the actual diameter of Betelgeuse? Compare your answer to the size of our Sun and the Earth-Sun distance.
The physical diameter of the sun will be 1309000km and the percentage of difference between the diameters will be 5.8%.
How to calculate the diameter?From the information, the sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. The angular diameter in radians will be:
= 0.5π / 180
= 0.008727 radians
Distance from the sun = 150 × 10^6
The physical diameter of the sun will be:
= 150 × 10^6 × 0.008727
= 1309000km
The difference between the diameters will be:
= 1390000 - 1309000
= 8.1 × 10^4.
The percentage of difference will be:
= (8.1 * 10^4) / 1390000 × 100
= 5.8%

At the independent record company where Chase works, the vinyl format has been experiencing a resurgence in popularity. Record sales are increasing by 6% each year. If 260,090 records were sold this year, what will annual sales be in 4 years?
If necessary, round your answer to the nearest whole number.
The annual sales is 322,511.6 in 4 years.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Record sales are increasing by 6% each year.
And, 260,090 records were sold this year.
Now, We have;
Record sales are increasing by 6% each year.
Hence, After 4 years;
The annual sales = 260,090 + 4 × 6% of 260,090
= 260,090 + 4 × 6/100 × 260,090
= 260,090 + 62,421.6

The value of x can be solved as follows, take note of the numbers you will need to drag to complete the equations:
4x + 12x = 320 (segment addition postulate)
16x = 320 (combining like terms)
x = 20 (dividing both sides by 16)

Answer:
The expression is a mathematical representation of an algebraic problem. The final form of the expression would be 75y -5 after combining like terms.

125y - 5 - 50y = (125-50)y -5 = 75y - 5
So the final simplified form of the expression is 75y -5.
Tim went 8 miles east and 15 miles north. Jan went 5 miles west and 12 miles north. How far apart are they?
Answer:
30miles
Step-by-step explanation:
As you can see in the graph, the distance between tim and jan is creating 2 right triangles
You can solve this using pythagoras theorem,
Triangle (1) :
[tex] x^{2} = {5}^{2} + {12}^{2} \\ {x} = \sqrt{{5}^{2} + {12}^{2} } \\ = \sqrt{169 } \\ = 13[/tex]
X (1) = 13 miles
Triangle (2):
[tex] {x}^{2} = {15}^{2} + {8}^{2} \\ x = \sqrt{ {8}^{2} + {15}^{2} } \\ = \sqrt{289} \\ = 17 [/tex]
X(2) = 17 miles
Now, the distance = x(1) + x(2)
= 13 + 17
=30 miles
Therefore, Tim and Jan are 30 miles apart
The value of y is directly proportional to the value of x. When x = 3.5, the value of y is 14.
What is the value of y when x = 28?
The value of y when x = 28 in the proportional relationship is 112.
How to find the value of y in the proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent.
The value of y is directly proportional to the value of x. When x = 3.5, the value of y is 14.
Therefore, let's find the constant of proportionality.
y = kx
14 = 3.5k
divide both sides by 3.5
k = 14 / 3.5
k = 4
Let's find the value of y when x = 28.
Hence,
y = 4x
y = 4 × 28
Therefore,
y = 112

What is an isosceles triangle?
An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having precisely two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.
Here, we have
Given: An isosceles triangle has congruent sides of 20 cm. The base is 12 cm.
An isosceles triangle has two congruent sides. The height of an isosceles triangle is also the median and the perpendicular bisector of the triangle dividing the base in half and forming two congruent right triangles.
we use the Pythagorean theorem to solve for the triangle's height.
a² + b² = c²
5² + h² = 20²

The way to determine x, which is the price per pound of the grapes is B. Subtract 5.28 from 7.32 and then divide the difference by 2.4.
How to find the price per pound ?To find the price per pound of the grapes, you first needed to find the price of the grapes alone, without the cost of the watermelons.
This price of the grapes can be found by the formula :
= Total cost of fruit - Cost of watermelon
= 7. 32 - 5. 28
= $ 2. 04
Then, you can find the cost of each pound of grapes by the formula :
= Cost of grapes / Pounds of grapes purchased
= 2. 04 / 2 . 40

(x-a)² + (y-b)² = r²
(x-2)² + (y-3)² = 4²
Expanding the brackets;
x² - 4x + 4 + y² - 6x + 9 = 16
x² + y² - 4x - 6x + 4 + 9 = 16
x² + y² - 4x - 6x + 13 = 16
x² + y² - 4x - 6x + 13 - 16 = 0
