Answer:

Area = 97.4 cm²

Step-by-step explanation:

a = 15 cm

        Area = \frac{ \sqrt 3}{4} a^2\\

                 =\frac{\sqrt 3}{ 4 } \times 15^2\\\\=\frac{\sqrt 3}{ 4 } \times 225\\\\= 97.4 \ cm^2

Q9. 

This question can't be answered. It is necessary to get the dimensions of the figure.

Q10. 

Let's find a conclusion having statements step by step.

a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:

\frac{\$0.85}{3}

b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:

(\frac{\$0.85}{3})n

The conclusion is: G. Multiplying n by the cost of 1 can.

Q11. 

Let's find a conclusion having statements step by step.

a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:

c = 40$

b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:

c = $40 + 1.70m

So, the answer is B.

82<br> R5<br> 6<br> ,92 5<br> 4 8<br> 12<br> 12<br> 0
Zarrin [17]

Answer:

  see below

Step-by-step explanation:

The first subtraction has a zero result (blue) from the thousands digit, so we know the dividend has 4 in that place. The 5 in the 1s place of the dividend is brought down to fill the space on the bottom line. 6 goes into that number 0 times, so the final quotient digit is 0.

  4,925 = 6×820 +5

or

  4,925 ÷ 6 = 820 r5
