Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams.
brilliants [131]

Answer

28 ounces = 793.79 grams

28 ounces = 0.79 kilograms.

Step by step explanation

1 ounce = 28.3495 grams

Now let's convert 28 into grams.

Here we have to multiply 28 by 28.3495

28 x 28.3495 = 793.787 grams

Now let's convert 793.787 into kilograms

1 kilograms = 1000 grams

793.787 grams = 0.79 kilograms

Aiden and Haisem are going to eat the same amount of hamburgers and fries, but from different restaurants. Aiden goes to Burger
Paha777 [63]

Answer:

the burgers be 3 and fries be 2

Step-by-step explanation:

The computation is shown below:

Let us assume burgers be x

And, the fries be y

Now according to the questiojn

1.25x + 0.50y = $4.75

1.50x + 0.99y = $6.48

Now multiply by 1.2 in the first equation

1.50x + 0.6y = $5.70

1.50x + 0.99y = $6.48

-0.39y = -0.78

y = 2

Now put the value of y in any of the above equation

1.25x + 0.50(2) = $4.75

x = 3

Hence, the burgers be 3 and fries be 2
