Answer:
16 1/3
Step-by-step explanation:
add 7 to 42 to get 49, then divide by 3 to get 16 1/3. :)
Box = b
Parrots = p
b/p = number of days it can support the parrots
Half a dozen = 6 (A dozen is 12)
1/6 = 15
To work out the percentage of '6' '5' is, use the equation
(5/6)*100 = 83.333....
Meaning that with one less bird, the box will support the birds for 16.666... (100 - 18.333...) longer
(15/100)*116.666... = 17.4999....
The box will sustain the parrots for 17.5 days
Answer:
C. f(x) = x - 7 all over 4
Step-by-step explanation:
NB: Let f(x) = y
Exchange X and Y
Make y the subject
f(x) = 4x + 7
y = 4x + 7
x = 4y + 7
x - 7 = 4y
x - 7 all over 4 = 4 ÷ 4
y = x - 7 all over 4
Answer: 29.2
Step-by-step explanation:
The lengths of the two longer legs are both ![\sqrt{8^2 + 4^2}=\sqrt{80}](https://tex.z-dn.net/?f=%5Csqrt%7B8%5E2%20%2B%204%5E2%7D%3D%5Csqrt%7B80%7D)
The lengths of the two shorter legs are both ![\sqrt{4^2+4^{2}}=\sqrt{32}](https://tex.z-dn.net/?f=%5Csqrt%7B4%5E2%2B4%5E%7B2%7D%7D%3D%5Csqrt%7B32%7D)
So ![P=2\sqrt{80}+2\sqrt{32} \approx 29.2](https://tex.z-dn.net/?f=P%3D2%5Csqrt%7B80%7D%2B2%5Csqrt%7B32%7D%20%5Capprox%2029.2)
