Explanation:

As that list above shows, adding any two sides results in a sum larger than the third remaining side. The conditions of the triangle inequality theorem have been met to allow for a triangle to be formed.

In general the triangle inequality theorem is:

The order doesn't matter. All that's important is that all three conditions are met.

Answer:

7598.8 [tex]cm^{2}[/tex]

Step-by-step explanation:

v (volume) = π[tex]r^{2}[/tex]h

v = 3.14 x [tex]11^{2}[/tex] x 20

v = 3.14 x 121 x 20

v = 7598.8

Answer:

7598.8 cm³

Step-by-step explanation:

Given :-

height = 20 cm

radius = 11 cm

value of π = 3.14

Formula to be used :-

Volume of cylinder = πr²h

Inputting the values :-

V = 3.14 x 11 x 11 x 20

= 3.14 x 121 x 20

= 3.14 x 2420

= 7598.8 cm³

Using linear function concepts, it is found that the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

For each car, Cart and Renta, the linear functions are given by:

C(k) = 90 + 0.15k

R(k) = 110 + 0.1k

Cart will cost less than Renta if:

C(k) < R(k)

Hence:

90 + 0.15k < 110 + 0.5k

0.05k < 20

k < 400

Hence, the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.

Answer:

The difference between a two step equation and a inequality equation is that two step equation you can isolate the variable and get the answer. However in a inequality equation you can only compare, for example A > 7

Step-by-step explanation:

A inequality compares not giving a clear answer. A two step equation lets you find a clear answer.

We see : 4x - 5y = -20

We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y

Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20

And -4x + 5y is indeed 20, so the answer is infinitely many solutions.

Answer:

infinitely many solutions

Step-by-step explanation:

4x - 5y = - 20 → (1)

- 4x + 5y = 20 → (2)

add (1) and (2) term by term

0 + 0 = 0

0 = 0 ← true statement

this indicates the system has infinitely many solutions

Answer:

x= 0 and y=1

Step-by-step explanation:

1st multiply the first equation by 3

3 (3x-2y=2)

9x-6y=6

multiply the next equation by 2

2 (5x-3y=3)

10x-6y=6

subtract equation 1 from 2

(10x-6y)-(9x-6y)=6-6

10x-9x-6y+6y=0

x=0

put X in equation 1

3 (0)-2y=2

-2y=2

y=-1

so X and y are 0 and -1 respectively

The rectangular prism having a length of 1 feet, width of 2 feet and that

https://brainly.com/question/16065961

The average conversion energy from producers to primary consumers will be 10%

As we know that energy can not be created nor be destroyed but it can only be transferred from one form to another.

So the primary consumers take energy as food and this energy is utilized in their metabolism and the remaining they transfer.

The average conversion energy from producers to primary consumers is only 10%.

This percentage actually holds true for all transfer of energy at any trophic level in the food chain.

Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy.

Thus the average conversion energy from producers to primary consumers will be 10%

Answer:

x = 12

y = -23

Step-by-step explanation:

to solve for this i think we have to do:

   y = -3x + 13

   -

   y = -2x + 1

-----------------------

   0 = -x + 12

-x = -12

x = 12

then i think.... i think you have to substitute to one of the equations

y = -3(12) + 13

y = -36 + 13

y = -23

then to check we substitute  to the second equation

-23 = -2(12) + 1 ?

-23 = -24 + 1?

-23 = -23
