A building with a height of 48 meter casts a shadow that is 30 meter long. A person standing next to the building casts shadow that is 0.8 meter long. How tall is the person
The height of the person is approximately 0.426 meters or 42.6 cm.
We can use the concept of similar triangles to solve this problem. The height of the building and the length of its shadow form a right triangle, with the height as the opposite side and the shadow as the hypotenuse. The person and their shadow also form a similar right triangle, with the height of the person as the opposite side and the shadow as the hypotenuse.
We can set up the following proportion:
(Height of building)/(length of shadow) = (height of person)/(length of shadow)
48/30 = h/0.8
Solving for h, we get:
h = (48/30) * 0.8 = 0.533 * 0.8 = 0.426
Therefore, the height of the person is approximately 0.426 meters or 42.6 cm.

Answer:
41x² - 27x + 27
Step-by-step explanation:
Perimeter of Rectangle:
= 2(20x²-12x+4) + 2(5x²-5x+15)
= 40x²-24x+8 + 10x²-10x+30
= 50x²-34x+38
Perimeter of Triangle:
= 6x²+6x+3x+3+3x²-2x+8
= 9x²+7x+11
Difference:
(50x²-9x²)+(-34x+7x)+(38-11)
= 41x² - 27x + 27
How do you find the slope of x =- 4?
The slope of x= -4 is unidentified.
The x= -4 is a vertical line and slope cannot be found.
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. [1] The letter m is frequently used to represent slope; the reason for this usage is unclear, although it may be found in O'Brien's (1844)[2] and Todhunter's (1888][3] formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively.
The ratio of the "vertical change" to the "horizontal change" between (any) two unique points on a line is used to compute slope.

Answer:
x° = 48°
Step-by-step explanation:
In order to solve this, we need to know that the sum of all inner angles of the triangle is equal to 180°. Based on this diagram we know that...
180° = 90° + 42° + x°
From here we know that...
x° = 180° - 90° - 42°
x° = 48°

Devin drove her truck. The fuel remaining in the truck's tank (in liters) as a function of distance (in kilometers) is graphed.
What is the approximate average fuel consumption rate, between the 100th kilometer and 400th kilometer?
Between the 100th and 400th kilometers, the average fuel consumption rate is 5/6 liters per kilometer.
What is the rate of change?A consequence of dividing the variation in a variable's function by the variation in the variable. For example The rate at which a distance changes in relation to time is known as velocity.
Given, Devin drove her truck. The fuel remaining in the truck's tank (in liters) as a function of distance (in kilometers) is graphed.
Since in the domain [100, 400] graph shows somewhat linear properties.
from the graph Fuel consumption at 100 = 375 liters
Fuel consumption at 400 = 125 liters
rate in a linear function between two points = (y₂ - y₁)/ (x₂ - x₁)
thus rate between [100, 400] = (375-125)/400-100
rate between [100, 400] = 250/300
rate between [100, 400] = 5/6litere per kilometer
therefore, the average fuel consumption rate, between the 100th kilometer and 400th kilometer is 5/6 liters per kilometer.

During the afternoon, an 18-foot tall tree casts a
shadow 25 feet long.
What is the approximate angle of elevation from the
end of the shadow to the top of the tree with respect
to the ground?
Using the slope concept, it is found that the approximate angle of elevation from the end of the shadow to the top of the tree with respect to the ground is of 35.75º.
What is a slope?The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
In this problem, the vertical change is the height of the tree, of 18 feet, while the shadow of 25 feet is the horizontal change, hence:
[tex]\tan^{\theta} = \frac{18}{25}[/tex]
[tex]\theta = \tan^{-1}{\frac{18}{25}}[/tex]
[tex]\theta = 35.75[/tex]
The approximate angle of elevation from the end of the shadow to the top of the tree with respect to the ground is of 35.75º.

A circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 4 m wide. Find
the area of the sidewalk in square meters. Use 3.14 for Pi
The area of the sidewalk is ____ m2.
Answer:
17m2
i think it is a right answer
Area of the circular sidewalk around flowerbed is 314 m² .
What is area?Area is the amount of space occupied by a two-dimensional shape. That is, it is a quantity that measures the number of unit squares that cover the surface of a closed figure. Standard area unit is square unit.
Given,
Diameter of flowerbed = 21m
radius = diameter/2 = 21/2 = 10.5 m
Area of flower bed A
= πr²
= 3.14(10.5)²
= 3.14(110.5)
= 346.185 m²
width of the sidewalk = 4m
radius of flower bed with sidewalk = 10.5 + 4 = 14.5m
Area of flower bed with sidewalk A'
= 3.14(14.5)²
= 3.14(210.25)
= 660.185 m²
Area of the sidewalk
= A' - A
= 660.185 - 346.185
= 314 m²
Hence, 314 m² is area of the circular sidewalk around flowerbed.

What is a opposite of 7?
-7 is the opposite of 7.
Simply adding a negative sign yields the negative number 7, which is the opposite of the positive number 7. 7 and 7 are the opposites of one another since they are both seven units apart from 0 on the number line.
The inverse of a number is the number on the other side of the 0 number line and at the same distance from 0. Oppositely positioned numbers on the number line. The opposite of an integer is its additive inverse. As a result, on a number line, the opposite of a number is the number that is located in the other direction from 0 but at the same distance from it.

Use point-slope form to find the equation of the line with a slope of
[tex] - \frac{1}{2} [/tex]
Express your answer in slope-intercept form. that passes through the point (6,-4)?
Answer:
y = -1/2 x - 1
Step-by-step explanation:
The expression in point-slope form is expressed as;
y-y0 = m(x-x0)
(x0,y0) = (6, -4)
slope m = -1/2
Substitute into the formula
y-(-4) = -1/2(x-6)
y+4 = -1/2(x-6)
2(y+4) = -(x-6)
2y+8 = -x+6
2y = -x+6-8
2y = -x-2
y = -1/2 x -2/2
y = -1/2 x - 1
Hence the answer in slope-intercept form is y = -1/2 x - 1
