Answer:

$63

Step-by-step explanation:

so we want to find 9/9 of her allowance, which is 100%

we could use a proportion:

let 'a' = full allowance

$\frac{28}{1}$ ÷ $\frac{4}{9}$ = $\frac{a}{1}$ ÷ $\frac{9}{9}$

when we divide fractions we multiply by the reciprocal to get:

28 x 9/4 = a

a = 252/4

a = 63

sqrt of 25 = c

c = 5

Answer:

3√41

Step-by-step explanation:

The diagonal can be gotten using the pythagoras theorem

d² = l²+w²

d² = 12²+15²

d² = 144 + 225

d² = 369

d = √9*41

d = 3√41

Hence the diagonal is 3√41

Find the missing number:

nirvana33 [79]

Answer:

20%

Step-by-step explanation:

Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:

1 × 1.25 = 1.25 units.

Now, to get back to 1 unit, we need to find:

1.25 × ? = 1

? = $\frac{1}{1.25}$ = 0.80

So, 100% - 80 % = 20%

A 20% decrease.

Not completely sure though.
