Answer:

4y+3x+17

Step-by-step explanation:

take the similar numbers and add them together.

1. -2y+6y = 4y

2. 5x-2x = 3x

3. 8+9 = 17

Put the numbers back together into the new and simplified equation: 4y + 3x + 17

and what is distance jeremy jumps from the ramp to the fire escape is _______ feet (round to the nearest tenth of a foot)
Cloud [144]

Answer:

sin(70°) =10/x

The distance Jeremy jumps from the ramp to the fire escape is <u>10.6</u> feet

Step-by-step explanation:

From the question shown in the picture attached, the vertical height Jeremy has to jump is: 15 - 5 = 10 ft

A right triangle is formed, where the angle between the hypotenuse (called x) and one of the legs is: 160° - 90° = 70°, and the vertical height Jeremy has to jump, is the leg opposite to that angle.

From sine definition:

sin(70°) = opposite/hypotenuse

sin(70°) = 10/x

x = 10/sin(70°)

x = 10.6 ft

Consider the following game, called matching pennies, which you are playing with a friend. Each of you has a penny hidden in you
Dahasolnce [82]

Answer:

a. The two players playing the game

b. No dominant strategy

c. No equilibrium

Step-by-step explanation:

a. The players are the two people playing the game of matching pennies

The strategy of the players are to meet the conditions of them keeping the pennies by having either heads or tails

The payoff of the game are as follows;

Player A keeps the two pennies when the outcome matches

Player B keeps the two pennies when the outcome does not match

The payoff of the game are as follows;

                                                Player A

                                             Head                          Tails

Player B  Head                     1, -1                              -1, 1

               Tails                      -1   1                               1, -1

Where:

x, y

x = Player A

y = Player B

1 = Getting to keep the two pennies

-1 = Losing a penny

b. There are no best strategy because the game is one of chance whereby the result of the strategy of one player depends on the side of the penny facing up by the other player.

c. There is no equilibrium as the possible outcomes are equal hence the outcomes can be even or one sided.

Select the three ratios that are equivalent to 2 adults5 children. CLEAR CHECK 8 adults20 children 5 adults8 children 20 adults5
xeze [42]

Answer:

Step-by-step explanation:

The ratio of adult to children is determined by number of adult / number of children.

We want to determine the three ratios that are equivalent to 2 adults 5 children. So we will divide each of the given number of adults and children.

1) 8 adults 20 children = 8/20 = 2/5

2) 5 adults 8 children = 5/8

3) 20 adults 50 children = 20/50 = 2/5

4) 4 adults 10 children = 4/10 = 2/5

So the three ratios that are equivalent to 2 adults 5 children are

8 adults 20 children,

20 adults 50 children and

4 adults 10 children
