Answer:

560

Step-by-step explanation:

To find the total combination you have to multiply the combination of entrees by the combination of sides. You have to use the nCr equation to find these separate equations. n is the number of items in the total of the set and r is the number of items you want to choose from the set.

nCr(8,2) = 28
nCr(6,3) = 20

28 * 20 = 560

Answer:

Susan needs 1 23/64 cubic feet of bird seed to fill the rest of the birdfeeder.

Step-by-step explanation:

I did the math.

0.11718 cubic feet of bird seed Susan need to fill the rest of the birdfeeder.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

We have,

It is filled with bird seed to a height of 5/8 feet as shown.

So, Susan need to fill the rest of the birdfeeder

= 5/8 x 1/2 x 3/8

= 15 / 128

= 0.11718 feet

Answer:

a = 14

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, sum to 180°

a² - 10a + 7a + 26 = 180

a² - 3a + 26 = 180 ( subtract 180 from both sides )

a² - 3a - 154 = 0 ← in standard form

(a - 14)(a + 11) = 0 ← in factored form

Equate each factor to zero and solve for a

a - 14 = 0 ⇒ a = 14

a + 11 = 0 ⇒ a = - 11

Since a > 0 , then a = 14

Answer:

The second option: 1/4 x (26 - 10) x 3

Step-by-step explanation:

"The difference of 26 and 10" indicates that those two numbers are going to be subtracted, which is why you get (26 - 10).

The "of" in "1/4 of" means that the value after the "of" is getting multiplied by the 1/4: 1/4 x (26 - 10)

The "3 times" means that the 3 is getting multiplied by whatever comes after it, which is why the answer is the second option: 1/4 x (26 - 10) x 3

Answer:

Student ticket: $12, Adult ticket: $14

Equations: 260=10x+10y, 94=2x+5y

Step-by-step explanation:

Set adult tickets as y

Set student tickets as x

First day: Total made is 260 so set that equal to 10x + 10y

--> 260=10x+10y

Second day: Total made is 94 so set that equal to 2x + 5y

--> 94=2x+5y

I find it easier to have simplified terms so simplify (divide by 2) the first equation to get: 130=5x+5y

All you have to do now is solve for the two variables.

94=2x+5y - (130=5x+5y) --> x=12, y=14

Answer:

-4/5y - 4/5x

Step-by-step explanation:

The fraction ( -4/5 ) will multiply each component in the bracket. That is the (y) and the (x)

So -4/5 × y gives you -4/5y

and -4/5 × x gives you -4/5x

Therefore you have -4/5y - 4/5x

Answer:

x = -11

Answer:

The deck of 52 playing cards is broadly classified into 2 which are further divided into 2 divisions.

Red(26 cards) and Black(26 cards).

The red cards are further divided into diamonds♦️ (13 cards) and hearts♥️ (13 cards).

The black cards are further divided into clubs♣️(13 cards) and spades♠️(13 cards).

In each division of 13 cards classified above, there are/is-

3 face cards- King, Queen, Jack

One ace card

9 number cards(numbered from 2–10)

So, there are twelve face cards in a deck.

When three cards are picked, you may pick any three face cards out of the 12 face cards.

P(getting 3 face cards)=

No. of favourable face cards/ Total cards I.e,

Answer:

the front face of the barn: 78m^2

Step-by-step explanation:

look at the photo

The area of a 2D form is the amount of space within its perimeter. The area of the front face of the barn is 78 m².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The diagram of the barn can be made as shown below. Therefore, the area of the front face of the barn is,

Area of the barn front = Area of the triangle + Area of the rectangle

                                     = (5 × 12) + (0.5 × 3 × 12)

                                     = 60 m² + 18 m²

                                     = 78 m²

Hence, the area of the front face of the barn is 78 m².

Answer:

[tex]\sqrt{202}[/tex] units or 14.2 units (rounded to the nearest tenth)

Step-by-step explanation:

To find the distance between a pair of two points, use the distance formula  [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:

[tex]d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}[/tex]  

So, as an exact answer, the distance is [tex]\sqrt{202}[/tex] units.

(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)  

Answer:

14.2

Step-by-step explanation:

All you need to do is plug the coordinates into the distance formula.

√(x2 - x1)² + (y2 - y1)²

√[8 - (-1)]² + [9 - (-2)]²

√(9)² + (11)²

√81 + 121

√202
