A bird sat 8 meters from the base of the tree , it flew in a straight line to reach the top of the tree, how tall is the tree? Round to the nearest hundredth
Answers
Answer:
Height of the tree = 6 meters.
Step-by-step explanation:
P.S - The exact question is -
The graph is as follows :
Here Base = 8 m , Hypotenuse = 10 m
As, we know that By Pythagoras theorem,
( Hypotenuse )² = ( Base )² + ( Perpendicular )²
⇒(10)² = (8)² + ( Perpendicular )²
Let the height of the tree = x
∴ we get
(10)² = (8)² + ( x )²
⇒100 = 64 + x²
⇒100 - 64 = x²
⇒36 = x²
⇒x = √36
⇒x = 6
∴ we get
Height of the tree = 6 meters.

an airplane is preparing to land at an airport it is 48,000 ft above the ground and it is descending at the rate of 3,300 ft per minute at the same airport another airplane is taking off and will ascend at the rate of 2,700 ft per minute when will the two airplanes be the same altitude and what will that altitude be
Answers
Answer:
8 minutes
alt. = 21,600 ft
Step-by-step explanation:
Isolate the variable.
48,000 - 3,300x = 2,700x
48,000 = 2,700x + 3,300x
48,000 = 6,000x
8 = x
8 minutes
Substitution.
48,000 - 3,300(8) = 2,700(8)
48,000 - 26,400 = 21,600
21,600 = 21,600
21,600 ft
The sum of four consecutive integers is 170. Write an equation that can be used to find the smallest integer.
Answers
Answer:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41
Step-by-step explanation:
Four consecutive integers is represented by:
First Integer = x
Second Integer = x + 1
Third Integer = x + 2
Fourth Integer = x + 3
The sum of four consecutive integers is 170.
x + x + 1 + x + 2 + x + 3 = 170
The Equation to find the smallest integer =
4x + 6 = 170
4x = 170 - 6
4x = 164
x = 164/4
x = 41
Therefore:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41

of
Answers
Answer:
17 black pencils
Step-by-step explanation:
Cost of black pencils; 15 cents each
Cost of colored pencils; 21 cents each
We are told that 24 pencils cost $4.02 = 402 cents
Let black pencils be x and let colored pencils be y.
Thus;
x + y = 24 - - - (eq 1)
Also,
15x + 21y = 402 - - - (eq 2)
From eq 1, y = 24 - x
Thus putting it in eq 2 gives;
15x + 21(24 - x) = 402
15x + 504 - 21x = 402
504 - 402 = 6x
x = 102/6
x = 17

8. Find the slope of the line that contains the
following points:
b. (6, -2) and (-3, 1).
Answers
Answer:
slope = [tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
1) Find the slope with the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] (in which [tex]m[/tex] represents the slope). The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. Thus, substitute the x and y values of the given points (6, -2) and (-3, 1) into the appropriate places in the formula and solve:
[tex]m = \frac{(1)-(-2)}{(-3)-(6)} \\m = \frac{1+2}{-3-6} \\m = \frac{3}{-9} \\m = -\frac{1}{3 }[/tex]
Thus, the slope is [tex]-\frac{1}{3}[/tex].

1. The corresponding sides of the triangles are congruent
2. The corresponding angles of the triangles are congruent
3. The corresponding sides of the image are 5 times as long as those of the pre-image
4. The image is a reduction of the pre-image
5. Neither the dilation nor the rotation change the shape of the triangle
6. The rotation reduces the size of the triangle
Please hurry, thank you!
Answers
Answer
The corresponding angles of the triangles are congruent
The image is a reduction of the pre-image
Neither the dilation nor the rotation change the shape of the triangle
Explanation:
For shapes to be similar:
1- there should be a ratio between the sides
2- angles in first shape should be congruent to angles in second shape
Now, a scale factor of 0.2 means that the sides of the image are 0.2 of the length of the original shape. However, angles are not changes
Let's check the choices:
1- The corresponding sides of the triangles are congruent:
This option is incorrect as dilation changes the lengths of the sides
2- The corresponding angles of the triangles are congruent:
This option is correct as neither dilation nor rotation alters the measures of the angles
3- The corresponding sides of the image are 5 times as long as those of the pre-image:
This option is incorrect as the sides of the image are only 0.2 times as long as those of the pre-image
4- The image is a reduction of the pre-image:
This option is correct as the sides of the image are 0.2 times those of the pre-image which means that the shape is reduced
5- Neither the dilation nor the rotation change the shape of the triangle:
This option is correct as both dilation and rotation are rigid transformations that do not alter the shape of the triangle (a triangle remains a triangle only with different side lengths)
6- The rotation reduces the size of the triangle:
This option is incorrect as rotation does not alter the size of the shape. It only changes its position
Hope this helps :)
Options 2, 4 and 5 are the correct answer.
Given that, a triangle is dilated by a scale factor of 1/5 and then rotated 90 degrees clockwise about the origin.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size.
Now, a scale factor of 0.2 means that the sides of the image are 0.2 of the length of the original shape. However, angles are not changes
Let's check the choices:
1- The corresponding sides of the triangles are congruent:
This option is incorrect as dilation changes the lengths of the sides.
2- The corresponding angles of the triangles are congruent:
This option is correct as neither dilation nor rotation alters the measures of the angles.
3- The corresponding sides of the image are 5 times as long as those of the pre-image:
This option is incorrect as the sides of the image are only 0.2 times as long as those of the pre-image.
4- The image is a reduction of the pre-image:
This option is correct as the sides of the image are 0.2 times those of the pre-image which means that the shape is reduced.
5- Neither the dilation nor the rotation change the shape of the triangle:
This option is correct as both dilation and rotation are rigid transformations that do not alter the shape of the triangle (a triangle remains a triangle only with different side lengths).
6- The rotation reduces the size of the triangle:
This option is incorrect as rotation does not alter the size of the shape. It only changes its position.
Therefore, options 2, 4 and 5 are the correct answer.
