Step-by-step explanation:
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
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

the points (17,10) and (8,10) fall on a particular line. what is its equation in slope-intercept form?
The equation of the line that passes through the points (17,10) and (8,10) is y = 10.
What is slope?Slope is a measure of the steepness of a line or a linear function. It is often represented by the letter "m" and is calculated as the ratio of the change in the y-coordinates of two points divided by the change in the x-coordinates of those same two points. In other words, it is the ratio of the "rise" to the "run" of the line. The slope of a line can be positive, negative, zero, or undefined.
What is slope intercept form?The slope-intercept form of a linear equation is a way to represent the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis, and it is represented by the value of b. This form of the equation is useful because it allows us to easily identify the slope and y-intercept of a line, as well as to graph the line using these values.
Calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the slope is:
m = (10 - 10) / (8 - 17) = 0
Use the point-slope form of the equation, y - y1 = m(x - x1)
In this case, the point slope form is:
y - 10 = 0(x - 17)
Simplify the above equation, we get:
y = 10
The equation of the line in slope-intercept form is:
y = 10

the height of the triangle.
The height of the triangle is 19.36cm.
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
h² = 400 - 25
h² = 375
h = 19.36cm
Hence, the height of the triangle is 19.36cm.

Step-by-step explanation:
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)

Zara part 2.4 pounds of grapes in the watermelon that cost $5.28. The total cost of the food was $7.32 which describes a way to determine X the price per pound for the grapes?
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
= $ 0. 85

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.

Tyshawn bought 7 chicken wings for $16.10. How much does each wing cost?
Answer: Each chicken wing costs $2.30 ✅
Step-by-step explanation:
To find out how much each wing cost, we need to divide the total cost of the wings by the number of wings.
We can use the formula:
Cost per item = Total cost / Number of items
In this case:
Cost per wing = $16.10 / 7 wings
To find the cost of each wing we divide 16.10 by 7.
$16.10/7 = $2.30
Each chicken wing costs $2.30

What is an exponential function?
An exponential function is one that has the formula f (x) = [tex]a^{x}[/tex], where x is a variable and a constant that serves as the function's base and must be greater than 0.
Given,
starting value = 6
constant ratio = 1/3
The general form of an exponential function
[tex]f(x) = ab^{x}[/tex]
where a = starting value i.e when x = 0
b = rate of change in exponential equation
So substituting our given values in the above equation, the exponential function is
[tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]
Now the value 6 can be divided by 3 only if the value of x = 1
[tex]f(1) =\frac{6}{3} = 2[/tex]
If x = 5, then equation becomes,
[tex]f(5) = 6 * (\frac{1}{3} )^5 = \frac{2}{81}[/tex]
So we cannot simply divide 6 by 3 without considering the value of x.
Therefore the correct equation of exponential function is
[tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]

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%
