Whats the answer PLS
Alexxx [7]

Answer:

48+23(6)½

Step-by-step explanation:

A = l × w

A =[(8-(6)^½) × (9+4(6)^½)]

A =8(9+4(6)^½) + [-(6)^½(9+4(6)^½]

A =(72 + 32(6)^½ - 9(6)^½ - 24)

A =(72 - 24 + 32(6)^½ - 9(6)^½)

A =(48 + 23(6)^½)

Mr. Jones wants to buy 6 tickets to a play. Each ticket costs $10. Mr. Jones has $45 in his pocket.
lawyer [7]

Answer:

He needs $15 more

Step-by-step explanation:

since each ticket costs $10 dollars, and there is 6 tickets, we need to multiply 10 x 6 to get the total cost of all tickets

10 x 6 = $60

To find how much more money he needs to buy all tickets, we need to subtract $45 from the total cost of tickets, which is $60

$60 - $45 = $15

Hope you understand this explanation!

A penny fell off the top of the building and hit the sidewalk below 3.1 seconds later how many meters did the penny fall to the
Sedbober [7]
To solve this we are going to use the free distance fallen formula: d=0.5gt^2
where
d is the distance
g is the gravity of Earth 9.8m/s^2
t is the time in seconds

We know from our problem that the penny fell off the top of the building and hit the sidewalk below 3.1 seconds later, so t=3.1. Lets replace the value in our formula:
d=0.5gt^2
d=0.5(9.8)(3.1)^2
d=47.089 meters

We can conclude that the penny fell a distance of 47.098 meters
