Dividing 21 by 7 will give to the proportion of 1:3 which is your scale for the bag with the 7inch base

Answer:

Scale factor = $\frac{1}{3}$

Step-by-step explanation:

In the figure attached, there are two bags. Larger one with the base of 21 in wide and another bag with a base of 7 in wide.

Since both the bags are similar in their shape.

Scale factor by which the smaller bag can be formed will be = $\frac{\text{Base length of the smallerer bag}}{\text{Base length of the larger bag}}$

= $\frac{7}{21}$

= $\frac{1}{3}$

Therefore, by multiplying every side of the larger bag with the scale factor $\frac{1}{3}$ we can get the dimensions of the smaller one.

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9

Zinaida [17]

The probability of profiting $5.2 million is 5% = 0.05

The probability of profiting $0.9 million is 50% = 0.5

The probability of breaking even, meaning no profit gain, is 45% = 0.45

Expected profit values of the CD is given by
(0.05×5.2) + (0.5×0.9) + (0.45×0) = 0.26+0.45+0 = 0.71 million

$\frac{2}{9}$ - $\frac{7}{12}$
Make the two fractions have common denominators. 9 and 12 both fit into 36, so multiply the top and bottom of $\frac{2}{9}$ by 4 and $\frac{7}{12}$ by 3.

$\frac{2}{9}$ ⇒ $\frac{8}{36}$
$\frac{7}{12}$ ⇒ $\frac{21}{36}$

Now that both fractions have common denominators, you can subtract them easily. Subtract the numerators (8 - 21) and keep the denominators the same.

$\frac{8}{36}$ - $\frac{21}{36}$ = $\frac{-13}{36}$

a = -13
b = 36

Answer:

$\frac{3^{12}}{3^{10}}$

Step-by-step explanation:

+ or x you plus the indices

- or divide you minus the indices

so 3^8 x 3^4 would be 3^12

and 3^2 x 3^8 would be 3 ^10
