A 20 feet tree casts a shadow that is 32 feet long. What is the distance from the top of the tree to the tip of the shadow? ​

Answer:

16.67%

Step-by-step explanation:

If area triples every year :

This means that :

With an initial area of 10;

Area at the end of the year = 3 * 10 = 30

Percentage increase per year :

(30 - 10) / 10 * 100%

(20 / 10) * 100%

2 * 100%

= 200% per year

Therefore, monthly increase %

Yearly % increase ÷ number of months in a year

200% ÷ 12

= 16.666666%

= 16.67%

Answer:

26. ∠ABC=44

27. ∠ABC=86

28. ∠ABC=116

Step-by-step explanation:

Since BD bisects ∠ABC in each diagram, ∠ABD=∠DBC.

26.

∠ABD=∠DBC

5x+2=7x-6

2x=8

x=4

∠ABC=∠ABD+∠DBC

=5(4)+2+7(4)-6

=20+2+28-6

=44

27.

∠ABD=∠DBC

11x-12=8x+3

3x=15

x=5

∠ABC=∠ABD+∠DBC

=11(5)-12+8(5)+3

=55-12+40+3

=86

28.

∠ABD=∠DBC

9x-23=5x+13

4x=36

x=9

∠ABC=∠ABD+∠DBC

=9(9)-23+5(9)+13

=81-23+45+13

=116

Answer:

The sprinkler will cover an area of [tex]50m^2[/tex]

Step-by-step explanation:

Given

[tex]Area = 240m^2[/tex]

[tex]\theta = 75^{\circ}[/tex]

Required

Determine the amount of area it can cover

The amount of area is calculated by calculating the area of a sector using:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * \pi r^2[/tex]

Where:

[tex]Area = \pi r^2 = 240m^2[/tex]

So, we have:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * 240m^2[/tex]

Substitute 75 for [tex]\theta[/tex]

[tex]Sector\ Area =\frac{75^{\circ}}{360^{\circ}} * 240m^2[/tex]

[tex]Sector\ Area =\frac{75^{\circ}* 240m^2}{360^{\circ}}[/tex]

[tex]Sector\ Area =\frac{75* 240m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000}{360} m^2[/tex]

[tex]Sector\ Area =50m^2[/tex]

Hence, the sprinkler will cover an area of [tex]50m^2[/tex]

What is scale on graph?

A scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data.

Given data ,

The distance between Louisville and Nashville = 1 3/4 inches

Scale of the map = 1 in : 100 miles

Now , 1 inch = 100 miles on the map

And , 1 3/4 = 7 / 4 inches

So , 7 / 4 inches = ( 7 / 4 ) x 100 miles

                          = 1.75 x 100 miles

                          = 175 miles

Hence , the distance between 2 cities is 175 miles

AHAHAHAHAHAHA SO JM IS EQUAL TO 29⁰ AND YOU NEED TO FIND ANGLE L BUT I DON'T KNOW WHAT IT EQUALS TO

Answer:

Step-by-step explanation:

180 is a straight line.

x is among that line so you must subtract the angles you know from 180.

180-54-38= 16

Answer:

If Y represents the number of green balls then it can have values from 0- 5

that is it can have all the value  0,1,2,3,4 and 5.

The probability of getting both balss green without replacement is 0.27778

Step-by-step explanation:

If the balls are not replaced then this is the dependent event .

The probability of getting the first ball is given be = 5/9

where 5 is the number of green balls and 9 is the total number of balls.

The probability of getting the second ball green given that first is also green is  = 5/9* 4/8= 20/72= 0.2778

If Y represents the number of green balls then it can have values from 0- 5

that is it can have all the value  0,1,2,3,4 and 5.

0 means there can be no green balls or white balls.

1 means there can be one green ball.

2 means there can be 2 green balls and so on.

In this exercise we have to use the knowledge of probability to calculate the chance of an event to occur, so you have to:

the chance of the event is 0.2778%

So organizing the information given in the statement is:

So with this information we can write that:

[tex]5/9* 4/8= 20/72= 0.2778[/tex]

Answer:  System of equations:

p + w = 175

p - w = 125

p is the plane's speed, w is the wind speed

The wind speed is 25 mph.  The plane's speed on a calm day is 150 mph.

Step-by-step explanation:

Solve by elimination: Add the equations. w "cancels" solve for p:

p + w = 175

p - w = 125

2p  = 300   divide both sides by 2

p = 150  the plane's speed

Substitute 150 for p and solve for w

150 + w = 175   Subtract 150 from both sides.

w = 25  the wind speed

Answer:

Step-by-step explanation:

In Rhombus, diagonals are angle bisectors.

So, ∠DAC = ∠CAB

∠A = ∠DAC+∠CAB

    = 53 + 53

∠A = 106

In Rhombus, opposite angles are equal.

∠DCB = ∠A

∠DCB = 106°
