Answer:

12/11

Step-by-step explanation:

Any work inside parentheses must be done first.  

Thus, start with (3 + 6); this equals 9.  Then the original expression becomes

36÷{12-(9)*5}

Multiplication and division are done before addition and subtraction.  Thus, the next stp is to multiply 9 and 5, obtaining 45, inside the parentheses.  This results in

36÷{12-45}, or 36÷{33}, which leads to the answer 36/33, or 12/11.

The diameter of the larger circle is 10.5 cm. The diameter of the smaller circle is 4.5 cm.
blondinia [14]
4.5 / 2 = 2.25cm radius for the smaller circle

3.14 (pi) × 2.25² = 15.89625cm²

10.5 / 2 = 5.25cm radius for the larger circle

3.14 × 5.25² = 86.54625cm²

86.54625 - 15.89625 = <span>70.65cm</span>² 

The answer is 70.7cm².

The question is:
Naddik [55]

Answer:

2.5 gallons of the 20% solution must be replaced by the 36% solution.

Step-by-step explanation:

.12(20 - x) + .36x = 20(.15)

2.4 - .12x + .36x = 3

2.4 - .24x = 3

- .24x =  - .6

.24x = .6

x = 2.5
