Answer:

It costs $1.50 or $1 and 50cents to play one game

Step-by-step explanation:

let x represent cost of games and y represent cost of rides

6x+4y=$22——equation 1

4x+8y=$32——equation 2

Multiply equation 1by 2

2(6x+4y=$22)=12x+8y=$44

Subtract equation 2from 1 to eliminate y

12x-4x+8y-8y=$44-32

8x=$12

x=$12/8=$1.5

Plug in x=1.5 into equation 2

4($1.5)+8y=$32

8y=$32-$6

8y=$26

y=26/8=$3.25

There is a fire in the third floor of a building, 22 feet above the ground. The fire truck has a 16-foot tall ladder on top, and

Over [174]

Answer: Yes the ladder will reach the fire

Step-by-step explanation: Please refer to the attached diagram for details.

The fire is at point A, while the top of the truck is at point C. The fire is actually burning at 22 feet off the ground, but because the fire truck itself is already 6 feet off the ground, the point that would serve as the base of the building would be 16 feet from the third floor (which is 22 feet minus 6 feet). Hence, point A to point B is 16 feet. So we need to calculate if line AC (from the truck to the fire at the third floor, labeled as b) shall equal the length of the ladder which is 16-foot long.

The angle of the ladder with the top of the truck is 75 degrees. Therefore,

Sin 75 = opposite/hypotenuse

Sin 75 = 16/b

By cross multiplication we now have

b = 16/Sin 75

b = 16/0.9659

b = 16.56

If the distance from A to C is 16.56 feet, then the 16-foot long ladder would reach the fire.

Find the measure of the side of the right triangle whose length is designated by a lowercase letter. (see attachment)

PilotLPTM [1.2K]

Answer:

a≈18 cm

Step-by-step explanation:

we have given:

an angle,

the adjacent side and

we need to find:

the opposite side

we know that the definition of

tan of an angle = opp. side/ adj. side

tan 61° = a/ 10

multiply both sides by 10

10 * tan61° = a

18.04047755 = a

18 ≈ a
