Answer:

Convectional rainfall. - Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it. This causes the air to expand and rise. As the air rises, it cools and condenses. ... If this process continues, rainfall will occur.

Orographic or relief rainfall. - Orographic or relief rainfall is caused when masses of air are forced up the side of elevated land formations, such as large mountains, often referred to as an upslope effect. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation.

Cyclonic or frontal rainfall. - Frontal or Cyclonic Rain is caused by cyclonic activity and it occurs along the fronts of the cyclone. It is formed when two masses of air of different temperature, humidity and density meets. For example meeting of moisture laden warm tropical wind with a polar air mass. A layer separating them is called the front.

Answer:

1681

Step-by-step explanation:

In a four digit perfect square, the first two digits and last two digits taken seperately are also perfect squares.

Therefore, the answer is 1681 because 1681=41*41 and

Answer:

80 cm

Step-by-step explanation:

The diagonals divide the rhombus into four congruent triangles.  The height of each triangle is 18/2 = 9, and the hypotenuse is 41.  Using Pythagorean theorem, the width of each triangle is:

c² = a² + b²

41² = 9² + x²

x = 40

Therefore, the longer diagonal is 2×40 = 80.

Answer:

$66.80

Step-by-step explanation:

multiply 5.85 by 8 and then add the product to 20 to get the total

After the eight weeks, Rita has $66.8 now.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given, Rita had $20.

Then she saved $5.85 each week for 8 weeks

That means,

she saved the amount,

= amount saved in one week multiplied by 8

She saved the amount

= $5.85 x 8

$5.85  × 8 means $5.85  is added eight times.

Rita saved the amount

= $5.85 x 8

= $46.8

To find the total amount;

$20 + $46.8 = $66.8

And bar diagram is in the attached image.

Therefore, she has $66.8.

Answer:

b=120

Step-by-step explanation:

Using proportions, it is found that the final price of the new computer monitor is given by:

b. 120

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

It is regularly priced at $200 but it is now on sale for 25% off, hence 75% of $200 is paid, so:

P1 = 0.75 x 200 = 150.

You can also use your 20% off coupon, hence the final price is of 80% of $150, then:

FP = 0.8 x 150 = $120.

Which means that option B is correct.

Answer:

  y > 0

Step-by-step explanation:

The range of the function ...

  y = e^(4x)

is the same as the range of any exponential function:

  y > 0

The function can take on any positive value, but will never be 0 or negative. It has a horizontal asymptote of y=0.

The range of the given function is y > 0.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given function is,

y = e⁴ˣ

This is an exponential function.

The range of any exponential function is all the real numbers which are greater than 0.

So here also, the range is all the real numbers which are greater than 0.

So range is y > 0.

Hence the correct option is B.

x₂ = 110

Step-by-step explanation:

Jogging pants design                Selling Price       Cost    

weekly production

 Design A    x₁                                     2500            1750

  Design B    x₂                                    2100            1200      

1. z ( function is : )

z = 2500*x₁  +  2100*x₂       to maximize

First constraint weekly production

 x₁    +   x₂    ≤  120

Second constraint Budget

1750*x₁  +  1200*x₂   ≤   150000      

Then the model is

z = 2500*x₁  +  2100*x₂       to maximize

Subject to

 x₁    +   x₂    ≤  120

1750*x₁  +  1200*x₂   ≤   150000  

General constraints   x₁  ≥  0           x₂   ≥ 0            both integers

Arrange similar algebra given there ... which is 'p' here , Now ;

10p -5= - 6+2p

or, 10p -2p = -6+5

( NOTE : Moving to opposite side , + becomes - and - becomes + )

10p -2p = -6+5

8p = - 1

p = - 1 / 8

Answer:

[tex]\frac{-1}{8}[/tex]

Step-by-step explanation:

You balance the equation by getting rid of the variable on one side and then you get rid of the constant on the other then solve from there

10-5=-6+2p

10p-5-2p=-6+2p-2p

8p-5+5-6+5

8p=-1

[tex]\frac{8p}{8}=\frac{-1}{8}[/tex]

p=[tex]\frac{-1}{8}[/tex]

To solve the equation we put -1/8 in the p spot:

10x-1/8-5=-6+2x-1/8

-1.25-5=-6+-0.25

-6.25=-6.25

The equation = -6.25

Answer: 24 schedules.

Step-by-step explanation:

Given data:

Courses planning to take = 4

Computer courses = 2

Courses from other areas = 2

Solution:

This problem can be solved using permutation.

For Computer science courses.

npr = n! / ( n - r )!

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

For other courses.

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

Jane can have a total of 24 different schedules.
