The picture below shows Annie and her younger brother Tommy’s money.

lawyer [7]

Step-by-step explanation:

Annie: 4 dollars = $4 11 dimes = 11 x 0.10 = $1.1 ( since 1 dime = 0.10 dollars)

4 pennies =4 x 0.01= $0.04 ( since 1 penny = 0.01 dollars)

Tommy 3 dimes = 3 x 0.10 = $0.3 3 pennies = 3x 0.01 = $0.03

Adding the values: 4 +1.1+0.04+0.3+0.03 = $5.47

Which expressions are equivalent to the given sort 40 (there is more than one and the one selected is correct)

Basile [38]

Answer:

$40 {}^{ \frac{1}{2} }$

Step-by-step explanation:

The last one is also the answer

Using the rational exponet rule,

$\sqrt[n]{ {x}^{m} } = x {}^{ \frac{m}{n} }$

Using this number,

$\sqrt{40}$

40 is the base so it will stay same. Remember this is a square root sign so our nth root is 2 so our denominator if the rational exponet is 2.

$40 {}^{1} = 40$

so our numerator is 1 so

$40 {}^{ \frac{1}{2} }$
