what is the answer ? can someone please explain ?

Step-by-step explanation:

Let t be the number of tables

Let c be the number of chairs

Total paint needed = 15858t + 2323c

Given t = 2 and c = 8, substitute t and c into expression to find total paint needed

Total Paint needed = 15858(2) + 2323(8)

= 31716 + 18584

= 50300 quarts of paint

Answer:35350

Step-by-step explanation:

its easy 32,550 - 34,150 it gives 1600 then divide by for because it id 4 years from 3 to 7 you get 400 thats your yearly raise then multiply by 3 because 7 to 10 is 3 years you get 1200 add ton 34150 and you get 35350

Speed per hour = distance / time

Speed = 73 1/3 / 3/2

Speed = 220/3 / 3/2

Speed = 220/3 x 2/3

Speed = 440 /9

Speed = 48 8/9 miles per hour.

= 20 + 60 + 48

= 128

Answer:

Nolan is right.

Step-by-step explanation:

14 seats initially so thats your starting number, the +14 has to be there. He is right in saying +3n because it adds 3 every succeeding row. It would be 3 ×2 if its the second row, so 6 plus 14 equals 20 for example

Solution :

Let A = Economics, B = Mathematics

n(A) = 311, n(B) = 243, [tex]$n(A \cap B) = 135$[/tex]

a). So, [tex]$n(A \cup B) = n(A) +n(B) - n(A \cap B)$[/tex]

                     = 311 + 243 - 135

                     = 419

b). n(A only) = 311 - 135

                   = 176

     n(B only) = 243 - 135

                   = 108

Exactly one of these two courses

  [tex]$=\frac{176+108}{500}$[/tex]

  = 0.568

c). Neither economics nor mathematics

    [tex]$=\frac{500-419}{500} $[/tex]

  [tex]$=\frac{81}{500}$[/tex]

 = 0.162

Answer:

1600. Because 20/4is 5 so there is 5time doubling so

first time 50 to 100

second time 100 to 200

third 200to400

fourth 400to 800

fifth 800to 1600.

In 20 years the number of Acromantula will be 1600 if the number of Acromantula is doubling in every 4 years.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given, the number of Acromantula doubles in every 4 years.

Also given that, There are 50 Acromantula in the forest.

In 4 years, the number of Acromantula wil be double of 50 i.e., 100

In 8 years, the number of Acromantula will be double of 100 i.e., 200

In 12 years, the number of Acromantula will be double of 200 i.e., 400

In 16 years, the number of Acromantula will be double of 400 i.e., 800

In 20 years, the number of Acromantula will be double of 800 i.e., 1600

Hence, In 20 years the number of Acromantula will be 1600

Answer:

Distance = 10.77 unit (Approx.

Step-by-step explanation:

Given:

Coordinate of Jenna's house = (2,4)

Coordinate of Zac's house = (-2,-6)

Find:

Distance

Computation:

Distance = √(X1 - X2)² + (Y1 - Y2)²

Distance = √(2 + 2)² + (4 + 6)²

Distance = √(2 + 2)² + (10)²

Distance = √16 + 100

Distance = √116

Distance = 10.77 unit (Approx.

Answer:

51 ≥ x

Step-by-step explanation

The greater than or equal to sign is a symbol that indicates that the value on the left hand side of the symbol is either greater than, or equal to the value on the right. This can also be read as the value on the left hand side is at least equal to the value on the right. X can equal 51 or it can be less. X cannot be greater than 51 in this inequality

Step-by-step explanation:

By Pythagoras' Theorem,

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

where c is always the largest number.

a and b can be interchangeable between the 2nd largest and the 3rd largest numbers.

Given a = 8, b = 15 and c = 17,

[tex] {a}^{2} + b {}^{2} = {8}^{2} + {15}^{2} \\ = 64 + 225 \\ = 289 \\ \\ {c}^{2} = {17}^{2} \\ = 289[/tex]

Since c^2 = a^2 + b^2 , 8 , 15 and 17 are pythagorean triplets.

Now let's move on to 9, 40 and 41.

[tex] {a}^{2} + {b}^{2} = {9}^{2} + {40}^{2} \\ = 81 + 1600 \\ = 1681 \\ \\ {c}^{2} = {41}^{2} \\ = 1681[/tex]

Since c^2 = a^2 + b^2 , 9 , 40 and 41 are pythagorean triplets.

Last let's move on to 4,7 and 8.

[tex] {a}^{2} + {b}^{2} = {4}^{2} + {7}^{2} \\ = 16 + 49 \\ = 65 \\ \\ {c}^{2} = {8}^{2} \\ = 64 [/tex]

Since a^2+b^2 IS NOT EQUAL to c^2, 4,7 and 8 ARE NOT pythagorean triplets.

Step-by-step explanation:

[tex] \frac{4}{ \sqrt{5} + \sqrt{2}} - \frac{3}{ \sqrt{5} - \sqrt{2} } = \\ = \frac{4( \sqrt{5} - \sqrt{2} ) - 3( \sqrt{5} + \sqrt{2} ) }{( \sqrt{5} + \sqrt{2} )\times ( \sqrt{5} - \sqrt{2} )} = \\ = \frac{4 \sqrt{5} - 4 \sqrt{2} - 3 \sqrt{5} - 3 \sqrt{2} }{5 - \sqrt{10} + \sqrt{10} - 2 } = \\ = \frac{ \sqrt{5} - 7 \sqrt{2} }{3} [/tex]

  properties of addition let you add, subtract, or rearrange the terms of a sum as may be needed

Step-by-step explanation:

Properties of addition let you rearrange a sum to make addition easier to do or to check mentally. They also let you "undo" addition or subtraction in the process of solving algebra problems. And, they let you add terms or constants that may make it easier to rearrange expressions, as in "completing the square."
