then he started to prepare the games for this 4 friends. if each game takes 5 minutes to prepare and he prepared a total of 5 games. how many minutes did it take for andrew to prepare all the games

Answer:

560

Step-by-step explanation:

The best way to do this is to write it out, but with large ones like this you should use the equation:

C(n,r) = n!/(r!(n-r)!),

where:

C(n,r) is the number of combinations;

n is the total number of elements in the set; and

r is the number of elements you choose from this set.

Given:

The figure of a triangular prism.

To find:

The surface area of the triangular prism.

Solution:

We know that, a triangular prism contains 2 congruent triangular surface and 3 rectangular surface.

Triangles have base 3 ft and height 2 ft.

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

[tex]A_1=\dfrac{1}{2}\times (3)\times (2)[/tex]

[tex]A_1=3[/tex]

Area of congruent triangles are congruent. So,

[tex]A_1=A_2=3\text{ sq. units}[/tex]

Now the three rectangular surface have dimensions 10 by 3, 10 by 3 and 10 by 3 because the triangles are equilateral and the length of the prism is 10 ft.

Area of a rectangle is

[tex]Area=Length\times width[/tex]

[tex]A_3=10\times 3[/tex]

[tex]A_3=30[/tex]

Dimensions of all three rectangles are same, therefore there areas are equal.

[tex]A_3=A_4=A_5=30[/tex]

Now, the total surface area of the prism is

[tex]A=A_1+A_2+A_3+A_4+A_5[/tex]

[tex]A=3+3+30+30+30[/tex]

[tex]A=96[/tex]

Therefore, the total surface area of the prism is 96 sq. ft.

Answer:

a² - a² = 0

hope it helps

Answer:

a ² - a ²= 1 a ² - 1 a ² = 0

you understand ?

Answer:

Your answer.

8x + y = 95.........(1)

2x + 7y = 71........... (2)

Y = 95-8x........ (3)

Put this value in eq 2

Then x = 11

Put x value in eq 3

Y = 7

/4   /4

x=3.75

Answer:

x = 3.75

Step-by-step explanation:

-3/4x = -5

(-3/4) -3/4x = -5(-3/4)

x = 3.75

Answer:

10x - 5

Step-by-step explanation:

Perimeter is found by adding up all the side lengths.

(2x-4) + (5x+6) + (3x-7) = 10x - 5

270 m³

Step-by-step explanation:

[tex]A_{triandle}[/tex] = [tex]\frac{5*12}{2}[/tex] = 30 m²

[tex]V_{triangular prism}[/tex] = 30 × 9 = 270 m³

Answer:

28 litres of mango juice will be required

Step-by-step explanation:

11). b. Internal dimensions of the rectangular prism are,

         Length = 40 cm

         Width = 20 cm

         Height = 35 cm

         Volume of the rectangular prism = Length × Width × Height

                                                                 = 40 × 20 × 35

                                                                 = 28000 cm³

          Since, 1 cm³ = 1 mL

          Therefore, 28000 cm³ = 28000 mL

          Since, 1000 mL = 1 L

          28000 mL = 28 L

          Therefore, to fill this jar 28 L of orange juice will be required.

Step-by-step explanation:

8r^2 eight r squared hope this is right

It is the simplest fraction form

Answer:

Altogether they made $24 which is enough to earn $12 each

Step-by-step explanation:

Important information:

1 cup: $0.75

4 cups = 1 quart

8 quarts of lemonade altogether

If we are looking to solve for the revenue earned based on quarts, we must first solve for how much money they make on 1 quart

Since 1 cup sells for $0.75 and 4 cups makes up a quart, we must multiply

0.75 × 4 = 3

They make $3 per 1 quart

We are looking for the amount for 8 quarts though, not just 1. Again we must multiply

3 × 8 = 24

They will make $24 if they sell all 8 quarts

The questions ask if they will each earn $12

Since there are two of them, Miles and Lucy, we must divide revenue earned by 2, the number of people

24 ÷ 2 = 12

$12

Answer:

820 feet

Step-by-step explanation:

We can use the rule of three in this scenario since this is a ratio problem with one unknown. To do this we simply multiply the diagonal values and divide by the final value. We know that there are a total of 3280.84 ft in a single kilometer, therefore...

1 km  ==  3280.84 ft

0.25 == x

(0.25 * 3280.84) / 1 = 820.21

Now we can see that there are 820.21 ft in the 0.25 kilometers. If we round this to the nearest foot we would round down to a total of 820 feet.
