I want to take the measurements of my 5 avocado trees and order their
heights from shortest to tallest, that way they can get enough sunlight to
continue growing. I have to worry about sea level, so those above sea
level get sunlight more easily (positive is above sea level, negative is
below sea level). The 5 heights are in feet: 6,-3, 2,-8,-6. Please help me
order them from shortest to tallest so I plant them in the right order to get
enough sunlight.

The perimeter of a rectangular
Sheet is 120 cm. If the length is 40 cm, find its breadth.
Also find its area.

Answers

Answer:

Breadth = 20 cm

Area = 800[tex]cm^{2}[/tex]

Step-by-step explanation:

Perimeter = 120 cm

length = 40 cm

Perimeter = 2 ( L + B )  

L - length     B - Breadth

120 = 2 ( 40 + B )

120 = 80 + 2B

2B = 120 - 80

2B = 40

B = [tex]\frac{40}{2}[/tex] = 20 cm

Breadth = 20 cm

Area of a reactangle = Length  × Breadth

= 40  × 20

= 800[tex]cm^{2}[/tex]

Kevin is 3 times as old as
Daniel. 4 years ago, Kevin was 5 times as old as Daniel.
How old is Daniel now?

Answers

Answer:

Daniel is 8 years old now.

Step-by-step explanation:

From the word problem we can make the following two equations:

Let "K" be Kevin's age now and let "D" be Daniel's age now, then...

K = 3D

K - 4 = 5(D - 4)

Now we substate the value of K, and get...

K - 4 = 5(D - 4)

3D - 4 = 5(D - 4)

3D - 4 = 5D - 20

3D - 5D = - 20 + 4

- 2D = - 16

D = 8

Therefore Daniel is 8 years old now.

70, 000 grams

Step-by-step explanation:

first convert grams to kilograms

there are 1,000 grams in a kilogram so multiply the 200 kg by 1,000

so

200 * 1000 = 200,000

200,000 grams of vegetables is what he started with

then you have to multiply that by the 35% that he sold

so

200,000 * 35% = 70,000

A jet airliner, flying initially 300 mi/hr due
east, suddenly enters a region where the
wind is blowing 100 mi/hr, pushing the
aircraft in the direction 30° north of east.
What is the resultant speed of the aircraft?

Answers

Answer:

389.82 mi/hr

Step-by-step explanation:

For us to find the resultant speed of the aircraft, we will simply add the vector components of the wind and the vector velocity of the aircraft to get;

V = v_xi^ + v_yj^

Now,

v_xi^ = (300 + 100cos30°)i^

v_yj^ = (100 sin 30°) j^

This gives;

v_xi^ = 386.6 i^

v_yj^ = 50 j^

Thus;

V = 386.6 i^ + 50 j^

Resultant velocity is;

|V| = √(386.6² + 50²)

|V| = √151959.56

|V| = 389.82 mi/hr

whats the ninth term of 25 20 15 10 5

Answers

Given:

The sequence is 25, 20, 15, 10, 5.

To find:

The ninth term of the given sequence.

Solution:

We have,

25, 20, 15, 10, 5

It is an AP because the difference between two consecutive terms are same.

Here,

First term (a) = 25

Common difference (d) = 20-25

                                       = -5

The nth terms of an AP is

[tex]a_n=a+(n-1)d[/tex]

Where, a is the first term and d is the common difference.

Putting a=25, n=9 and d=-5 to get the 9th term.

[tex]a_9=25+(9-1)(-5)[/tex]

[tex]a_9=25+(8)(-5)[/tex]

[tex]a_9=25-40[/tex]

[tex]a_9=-15[/tex]

Therefore, the ninth term of the given sequence is -15.
