Drag each tile to the correct box

ValentinkaMS [17]

Answer:

Arranging the solutions from the least to the highest;

1. 1.743 x 10⁻²

2. 3.626 x 10⁻²

3. 4.64 x 10⁻²

4. 3.162 x 10²

5. 4.214 x 10³

Step-by-step explanation:

The solutions of the mathematical expression are calculated as follows;

$1. \ \ (4.3\times 10^6)(9.8\times 10^{-4}) = (4.3\times 9.8\times 10^{6-4}) = (42.14\times 10^2)= 4.214 \times 10^3$

$2. \ \ (2.9\times 10^7)(1.6\times 10^{-9}) = (2.9\times 1.6\times 10^{7-9}) = 4.64\times 10^{-2}$

$3. \ \ \frac{(4.7 \times 10^3)(8.6\times 10^{-7})}{(3.8\times 10^{-4})(6.1 \times 10^2)} = \frac{(4.7\times 8.6\times 10^{3-7})}{(3.8\times 6.1\times 10^{-4+2})} = \frac{4.042 \times 10^{-3}}{2.318\times 10^{-1}} = 1.743\times 10^{-2}$

$4. \ \ (4.9\times 10^3)(7.4\times 10^{-6}) = (4.9\times 7.4\times 10^{3-6}) = 3.626\times 10^{-2}$

$5. \ \ \frac{(3.9 \times 10^5)(8.7\times 10^{-3})}{(3.7\times 10^{-5})(2.9 \times 10^8)} = \frac{(3.9\times 8.7\times 10^{5-3})}{(3.7\times 2.9\times 10^{-4 +8 })} = \frac{3.393 \times 10^{-1}}{1.073\times 10^{-3}} = 3.162\times 10^{2}$

Arranging the solutions from the least to the highest;

1. 1.743 x 10⁻²

2. 3.626 x 10⁻²

3. 4.64 x 10⁻²

4. 3.162 x 10²

5. 4.214 x 10³

Answer:

interchange the role of x and y

x=9y+5

x-5=9y

x-5 =y

so,f^-1(x)= x-5

9

Art wants to cover an isosceles triangle with a height of 9 centimeters and a base of 7 centimeters in fabric. How much fabric d

s2008m [1.1K]

Answer:

31.5 cm²

Step-by-step explanation:

Calculate area of a triangle with this formula:

Area = $\frac{1}{2}$ base * height

Substitute in known values

Area = $\frac{1}{2}$ 7 * 9

Multiply 7 by 1/2

Area = 3.5 * 9

Multiply

Area = 31.5 cm²

Hope this helps :)

Can you please give the answer with the step by step as well.

gogolik [260]

Answer:

easy :) answer is 12x-8y

Step-by-step explanation:

all you do is combine like terms

1. the 10x + 2x which is 12x

2. (this part gets tricky) you have a NEGITIVE 5 minus 3 so if you are subtracting by a negitive number you add (5+3=8) and keep the negitive (-8y)
