Find the slope of the line.

Answer: Length of shorter tree = 7.2 feet .

Step-by-step explanation:

Given : Height of two trees as 50 feet and 20 feet.

At same time the angle made by sun rays would be same for both trees.

Both trees are vertical to the ground making right angle so triangles made by both triangles must be similar.

Corresponding sides of similar triangles are proportional.

So [tex]\dfrac{\text{length of the shadow of the shorter tree}}{\text{height of shorter tree}}=\dfrac{\text{length of the shadow of the bigger tree}}{\text{height of bigger tree}}\\\\=\dfrac{\text{length of the shadow of the shorter tree}}{20}=\dfrac{18}{50}\\\\\Rightarrow\ \text{length of the shadow of the shorter tree}=\dfrac{18}{50}\times20\\\\\Rightarrow\ \text{length of the shadow of the shorter tree} = 7.2[/tex]

So, Length of shorter tree = 7.2 feet .

Answer:

x^9

Step-by-step explanation:

When we multiply exponents with the same base, we add the powers

a^b * a^c = a^(b+c)

x^3 * x^6 = x^(3+6) = x^9

Step-by-step explanation:

[tex](x {}^{3}).( {x}^{6} ) = (x {}^{3 + 6} ) = {x}^{9} [/tex]

Answer:

Slope: -1/4, y-intercept: -2.

Step-by-step explanation:

The line intersects the y-axis at -2. This means that the y-intercept is -2. The slope is -1/4 because since the slope is rise over run, you go up one and then to the left 4 from the y-intercept. When you do this you see that from both A to B, you will end up on the same line.

Hope this helps!

Answer:

Odd degree polynmial

Answer:

r = 16

Step-by-step explanation:

Cross multiply:

4 x 20 = r x 5

Simplifying

4 x 20 = r x 5

Multiply 4 x 20

80 = r x 5

Reorder the terms for easier multiplication:

80 = 5r

Solve

80 = 5r

Solve for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-5r' to each side of the equation.

80 + -5r = 5r + -5r

Combine like terms: 5r + -5r = 0

80 + -5r = 0

Add '-80' to each side of the equation.

80 + -80 + -5r = 0 + -80

Combine like terms: 80 + -80 = 0

0 + -5r = 0 + -80

-5r = 0 + -80

Combine like terms: 0 + -80 = -80

-5r = -80

Divide each side by '-5'.

r = 16

Simplify

r = 16

Answer:

6.4

Step-by-step explanation:

Answer:

6.5 kilometers

Step-by-step explanation:

Step-by-step explanation:

x intercept is when y = 0 and y intercept is when x = 0 hence, x intercept is : x = -56 hence (-56, 0) and y intercept is: 4y = -56 y = -14 hence (0, -14)

Step-By-Step Explanation:

Answer:

reflex angle EOC = 250°

Step-by-step explanation:

reflex angle EOC

= angle COA + angle DOA + angle DOB + angle BOE

angle DOB = 40° (given)

angle DOB + angle DOA = 180° (linear pair)

angle DOA = 180° - 40°

angle DOA = 140°

angle COA + angle DOA = 180° (linear pair)

angle COA = 180° - 140°

angle COA = 40°

angle COA + angle BOE = 70° (given)

angle BOE = 70° - 40°

angle BOE = 30°

Now,

we have,

reflex angle EOC = 40° + 140° + 40° + 30°

= 250°

Answer:

50 seconds in order to assemble 20 pizza boxes

Step-by-step explanation:

there are two ways to solve this the first way is divide 20 by 2 which is 10 and then multiply 10 by 5 the reason to this is because we know that for every 2 it takes 5 seconds.

the second way takes longer but you write:

2, 2, 2, 2, 2, 2, 2, 2, 2, 2,

5, 5, 5, 5, 5, 5, 5, 5, 5, 5,

so here were basically writing the number 2 10 times because when u count that u can see that it equals 20 and then since for every 2 boxes it takes 5 seconds u put the 5 under each 2 so then you would count the 5s, like 5, 10 15, 20... and so on and u will see that its 50 which means 50 seconds.

Answer:

Step-by-step explanation:

We know that the angle of elevation is 8 degrees.

We know that the height of the opposite side of the angle is 3 feet.

We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)

We can do this with tangent

[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]

The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets

Using SOHCAHTOA :

Tanθ = Opposite / Adjacent

Tan(8°) = 3 / d

0.1405408 = 3 / d

0.1405408d = 3

Divide both sides by 0.1405408 to isolate d

0.1405408d / 0.1405408 = 3 / 0.1405408

d = 21.34 feets

Therefore, the distance of the ramp from the door should be 21.34 feets

Answer:

1/4

Step-by-step explanation:

The total number of girls on the team is 12

3 scored over 10 points

The fraction scoring over 10 points will be 3/12 = 1/4

The answer was obtained by dividing the number of girls who scored over 10 points by the total number of girls on the team

We then proceeded to write our answer in a fraction form

Answer:

1/4.

Step-by-step explanation

Since 3 of them scored over 10 points in the game, and there were 12 girls. You have to divide 12 by 3, which equals 1/4.

Answer:

P'(3, - 3 )

Step-by-step explanation:

Given

M(- 3, 4 ) → M'(- 1, - 1 )

To obtain the image  2 is added to the x- coordinate and 5 is subtracted from the y- coordinate, that is

Translation rule is

(x, y ) → (x + 2, y - 5 ), thus

P(1, 2 ) → P'(1 +2, 2 - 5 ) → P'(3, - 3 )

Answer:

y = 5

x = 14

Step-by-step explanation:

AOC=25

AOL=90

Therefore COL = 65

COM is a 90 degree angle since MOD is 90 degrees

COM - COL = 90 - 65 = 25

5y = 25

y=5

LOB = 90

5y + 3x + 23 = 90

5(5) + 3x +23 = 90

25 + 3x + 23 = 90

48 + 3x = 90

3x= 90 - 48

3x = 42

x= 14

Answer:

x = 14, y = 5

Step-by-step explanation:

MOB = LOC

(3x + 23) + 25 = 90

3x + 23 = 65

3x = 42

x = 14

3(14)+23 + 5y = 90°

5y = 25

y = 5
