Answer:

a) 10 salads

b) 5 Choose 2 and 5 Choose 3 result in the same amount

Step-by-step explanation:

a) ₅C₂ = 5! / (5-2)! 2!

= 5! / 3! 2!

= (5 × 4) / 2

= 10 salads

b) ₅C₃ = 5! / (5-3)! 3!

= 5! / 2! 3!

= (5 × 4) / 2

= 10

Which expression is equivalent to 24 Superscript one-third?

Ivahew [28]

Answer:

See explanation

Step-by-step explanation:

The given expression is: $(24)^{\frac{1}{3}}$

Recall that 24=3*8

$\implies(24)^{\frac{1}{3}}=(8*3)^{\frac{1}{3}}$

Recall again that:

$(a*b)^n=a^n*b^n$

$\implies (8*3)^{\frac{1}{3}}=(8)^{\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=(2^3)^{\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=2^{3*\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=2*(3)^{\frac{1}{3}}$

We rewrite in radical form to obtain

$\implies (8*3)^{\frac{1}{3}}=2\sqrt[3]{3}$

HELP

fiasKO [112]

1000 divided by 100 is 10. 10 x 5 is 50. After the first year, Sue has 1050. But compound interest is interest on the amount AFTER the amount is added, so she will now earn interest on 1050. 1050 / 100 is 10.5. 10.5 x 52.50.
52.50 + 50 = 102.50. The answer is D. Hope this helps :)

Are Transformations used to create Similar Figures EXPLAIN

kotykmax [81]

Answer:

sometimes

Step-by-step explanation:

Similar figures can also be a different size, as long as they're the same shape. So both rigid transformations and dilations can create similar figures.
