Answer:

45 kg = Bethan's share

105 kg = Jade's share

Step-by-step explanation:

Let 3x = Bethan's share

4x = Noah's share

7x = Jade's share

Since Noah's share was 60, then 4x = 60

x = 15

3(15) = 45 kg = Bethan's share

7(15) = 105 kg = Jade's share

$\sf{Hey!}$

$\boxed{\underline{Question:}}$

$(\frac{1}{5})^4 = \frac{1}{632}$

If you want the decimal.

$^A^n^s^w^e^r^~:$

$0.0016.$

$\huge\bold{\textbf{\textsf{{\color{EXPLANATION :}{}}}}}$

Apply exponent rule: $(\frac{a}{b})^c =\frac{a^c}{b^c}$

= $\frac{1^4}{5^4}$

$1^4=1$

$=\frac{1}{5^4}$

$5^4=625$

= $\frac{1}{625}$

Hope It Helps. . .

There is an animal farm where chickens and cows live. All together, there are 84 heads and 210 legs. How many chickens and cows

Ira Lisetskai [31]

1 Chicken have = 2 legs

1 Cow have = 4 legs

No of cows = x

No of chickens = y

Total no of legs = 4x + 2y = 210.............(1)

Total No of heads = x + y = 84................(2)

x = 84 - y....( from (2) )

Substituting the above equation in (1)

4 ( 84 - y) + 2y = 210

336 - 4y + 2y = 210

336 - 2y = 210

-2y = -126

= y = 63

No of cows = 84-63 = 21

∴ Total no of cows = 21

Total no of chickens = 63
