Answer: [tex]z=91.6[/tex]

Step-by-step explanation:

A pentagon has 5 sides and 5 angles and equals up to 540 degrees

So we need to make the equation of

[tex]145+120.1+112.3+71+z=540[/tex]

[tex]448.4+z=540[/tex]

[tex]448.4+z=540\\-448.4 = -448.4[/tex]

[tex]z=91.6[/tex]c

To check work just plug in 91.6 for z in the equation that was created [tex]145+120.1+112.3+71+91.6=540[/tex]

Answer:

  a. 0.41

  b. 0.22

Step-by-step explanation:

The sum of probabilities over all outcomes is 1. This fact can be used to fill the table. The other questions can be answered by reference to the table.

__

The total of all probabilities is 1:

  k +0.23 +0.18 +0.26 +2k = 1

  3k = 0.33 . . . . . . . collect terms, subtract 0.67

  k = 0.11 . . . . . . . divide by 3

  2k = 0.22 . . . . find 2k

Then the table is ...

  [tex]\begin{array}{c|ccccc}n&1&2&3&4&5\\p(n)&0.11&0.23&0.18&0.26&0.22\end{array}[/tex]

Landing on 2 or 3 are mutually exclusive outcomes, so the probability of one or the other is the sum of their individual probabilities:

  p(2 or 3) = 0.23 +0.18

  p(2 or 3) = 0.41

__

The table tells us ...

  p(5) = 0.22

Subsitute the required values,

[tex]\sf{ 20 = 0{\times}2 {\times} }{\sf{\dfrac{1}{2}}}{\sf{{\times}a(2)^{2}}}[/tex]

[tex]\sf{ 20 = }{\sf{\dfrac{1}{2}}}{\sf{{\times}4a}}[/tex]

[tex]\sf{ 20 = 2a }[/tex]

[tex]\sf{ a = }{\dfrac{ 20}{2}}[/tex]

[tex]\sf{ a = 10\:m/s^{2}}[/tex]

Hence, The acceleration of the jeepeny is 10 m/s² .

Here, we have

Therefore,

By using second equation of motion

[tex]\sf{ S = ut {\times} }{\sf{\dfrac{1}{2}}}{\sf{at^{2}}}[/tex]

Subsitute the required values,

[tex]\sf{ S = 0{\times}3 {\times} }{\sf{\dfrac{1}{2}}}{\sf{{\times}4(3)^{2}}}[/tex]

[tex]\sf{ S = }{\sf{\dfrac{1}{2}}}{\sf{{\times}4(9)}}[/tex]

[tex]\sf{ S = }{\sf{\dfrac{1}{2}}}{\sf{{\times}36}}[/tex]

[tex]\sf{ S = 18 \: m }[/tex]

Hence, The coin will reach 18 m after 3 seconds.

Here,

So,

By using third equation of motion

[tex]\sf{ v^{2} = u^{2} + 2gs }[/tex]

Subsitute the required values,

[tex]\sf{ v^{2} = 0^{2} + 2{\times}9.8{\times}45 }[/tex]

[tex]\sf{ v^{2} = 90{\times}9.8}[/tex]

[tex]\sf{ v^{2} = 882 m}[/tex]

[tex]\sf{ v = \sqrt{882} m}[/tex]

[tex]\sf{ v = 29.7 m/s}[/tex]

Hence, The final velocity of the stone when the stone hits the ground is 29.7 m.

Hope that helps!

Step-by-step explanation:

seems to be multiplication, because the differences between the numbers change.

so, let's find the factor.

2 × f = 5

f = 5/2

5 × f = 5 × 5/2 = 25/2

ok, the factor 5/2 is confirmed.

a1 = 2

a2 = a1 × 5/2 = 2 × 5/2 = 10/2 = 5

a3 = a2 × 5/2 = a1 × 5/2 × 5/2 = 2 × 5/2 × 5/2 = 25/2

an = an-1 × 5/2 = a1 × (5/2)^(n-1) = 2 × (5/2)^(n-1)

a9 = 2 × (5/2)⁸ = 2 × 390,625/256 =

= 390,625/128 = 3,051.7578125

The geometric sequence's 9th term will be 3,051.7578.

A geometric sequence is one in which each term is obtained by multiplying the previous term by the same number throughout the series.

Let a₁ represent the first term and r represent the common ratio. The geometric sequence's nth term is then given as,

aₙ = a₁ x (r)ⁿ⁻¹

The sequence is given below.

2, 5, [tex]\dfrac{25}{2}[/tex],

The first term is 2. And the common difference is given as,

[tex]r = \dfrac{5}{2}[/tex]

r = 2.5

Then the 9th term is given as,

a₉ = 2 x  (2.5)⁹⁻¹

a₉ = 2 x (2.5)⁸

a₉ = 2 x 1525.8789

a₉ = 3,051.7578

The 9th term of the geometric sequence will be 3,051.7578.

Answer:

80%

Step-by-step explanation:

using equivalent fractions:

40/50 = 80/100 = 80%

also since 50 is half of 100 (in other words 100%), you can just multiply 40 by 2 to get a number out of 100 which is your percentage

Answer:

(-3,1)

Step-by-step explanation:

As their are two lines so these are simultaneous linear equations

Hence this is (-3,1)

Note: The solution of a graph is the intersection of 2 lines.

Plotting the solution on the graph:

To plot the solution on the graph,

Identifying a solution on the graph:

To identify the solution, you willl need to determine it's coordinates.

     1. Determine the x and y coordinate by drawing a line going                                 downwards and rightwards. Keep in mind that the                                               intersection of the lines on the x and y axis are the x and y                               coordinates repectively.

    2. The x and y coordinate obtained should be put in (x,y) form.

Answer:

  1680

Step-by-step explanation:

To find the product of the two numbers, you can work out the values of the numbers, or you can work directly with the sum and difference figures.

__

We note that the square of a sum is ...

  (a +b)² = a² +2ab +b²

and the square of a difference is ...

  (a -b)² = a² -2ab +b²

The difference of these squares is ...

  (a +b)² -(a -b)² = (a² +2ab +b²) -(a² -2ab +b²) = 4ab

__

That is, dividing the difference of the squares of the sum and difference by 4 will give the desired product:

  P = (83² -13²)/4 = (6889 -169)/4 = 6720/4 = 1680

The product of the two numbers is 1680.

_____

Additional comment

If we factor the formula we derived, we find ...

  P = ((a +b)² -(a -b)²)/4 = ((a +b) +(a -b))/2 × ((a +b) -(a -b))/2

This simplifies to ...

  (2a)/2 × (2b)/2 = a × b

In short:

Using this fact, we find a=(83+13)/2 = 48; b=(83-13)/2 = 35, and the product is (48)(35) = 1680, as above.

The required factorized form of the given expression is 50(x+2), where 50 is the greatest common factor (GCF).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

We have been given that the expression below as

50x + 100

We have to determine the factor of the expression 50x + 100

First, we have to find the Greatest Common Factor (GCF).

GCF = 50

2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

50(50x/50 + 100/50)

Simplify each term in parentheses.

50(x+2)

Therefore, the required factorized form of the given expression is 50(x+2).

Answer:

The distributive property states that you can "distribute" the contents of one parentheses into the other to find an answer.

Let's first break down the larger number in the second parentheses:

400 + 10 + 5.

Then, let's multiply all those numbers by 3.

400 x 3 = 1200. 10 x 3 = 30. 5 x 3 = 15.

Then add up all the numbers and you get 1245.

The surface area of the roof is the amount of space on it

The surface area of the roof is 600 square meters,

From the complete question, we have the parameters for the roof:

The surface area of the roof is calculated using:

[tex]A = b^2 + 2b \sqrt{\frac{b^2}4 + h^2}[/tex]

So, we have:

[tex]A = 15^2 + 2 * 15 \sqrt{\frac{15^2}4 + 10^2}[/tex]

Evaluate the exponents

[tex]A = 225 + 30 * \sqrt{\frac{225}4 + 100[/tex]

The equation becomes
