A group of nine friends po to a baseball game. Each friend buys either a hamburger or hot dag at the game

The group buy 6 hot dogs and 3 hamburgers for a total of $27.75.

• A hamburger costs $1.75 more than a hot dog.

What is the cost of a hamburger?

$4.25

Step-by-step explanation:

Let the cost of the hotdog be x

Since a hamburger costs $1.75 more than a hot dog. Then, the cost of the hamburger will be:

= x + 1.75

We are further told that the group buy 6 hot dogs and 3 hamburgers for a total of $27.75. This can then be represented in an equation as:

6 hot dogs + 3 hamburger = $27.75

(6 × x) + 3 × (x + 1.75) = 27.75

6x + 3x + 5.25 = 27.75

9x = 27.75 - 5.25

9x = 22.50

x = 22.50/9

x = 2.50

The hotdog cost $2.50

Cost of hamburger = x + 1.75

= $2.50 + $1.75

= $4.25

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
