Answer:
The answer is A. $1.35
Step-by-step explanation:
Two $10 bills are equal to $20.
Your change is $7.85
So if you subtract $7.85 from $20 you will come up with $12.15.
$12.15 is how much money you spend on mini burgers.
You can then divide how much money you spent with how many burgers you bought.
12.15 divided by 9 gives us 1.35. So each burger was $1.35.
No teaspoon would take forever if you want though but you can use this instead quarts it's way easier oh and 1 gallon is 4 quarts hoped this helped.
Answer:the number of black tiles that Todd used is 27
Step-by-step explanation:
Let x represent the number of black tiles that Todd used.
Todd has 21 white tiles and some black tiles to make a mosaic. Each tile has an area of 3 square. It means that the total area of the white tiles is 21 × 3 = 63 cm^2
The total area of the white tiles is x × 3 = 3x cm^2
The mosaic has a total area of 144 Square centimeters. It means that
3x + 63 = 144
3x = 144 - 63 = 81
x = 81/3 = 27
What if I wrote + 38 - 28 .
Would you be able to solve it that way ?
They're both the same number.
Answer:
8.49 × 10⁻³
Explanation:
Standard form of a number: A. × 10ᵇ
(where 'A' is the number, b is the exponent over 10)
For the number "0.00849", move the decimal point 3 places right so the exponent of 10 is -3.
Standard form: 8.49 × 10⁻³
Other examples of standard/scientific forms are: standard forms
i) 0.043, move the decimal point 2 places right = 4.3 × 10⁻²
ii) 4030, move the decimal point 3 places left = 4.03 × 10³
