Answer: Mom bought 10 chickens
Step-by-step explanation: if each chicken had 2 wings and there were 20 wings you divide
Answer:
10,000
Step-by-step explanation:
We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.
1 m = 100 cm
10 m = 1000 cm
40 m = 4000 cm
area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2
area of tile = s^2 = (20 cm)^2 = 400 cm^2
number of tiles = 4,000,000/400 = 10,000
Answer: 10,000 tiles

<h3>We have to determine</h3>
The equivalent expression to the given expression.
<h3>According to the question</h3>
To determine the equivalent relation following all the steps given below.
Expression; ![\dfrac{\sqrt{2}}{\sqrt[3]{2} }](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B%5Csqrt%5B3%5D%7B2%7D%20%7D)
The equivalent expression is;
![= \dfrac{\sqrt{2}}{\sqrt[3]{2} }\\\\= \dfrac{2^{\frac{1}{2}}}{2^{\frac{1}{3}}}\\\\ = 2^{\frac{1}{2}-\frac{1}{3}}\\\\ = 2 ^{\frac{3-2}{6}}\\\\= 2^{\frac{1}{6}}\\\\= \sqrt[6]{2}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B%5Csqrt%5B3%5D%7B2%7D%20%7D%5C%5C%5C%5C%3D%20%5Cdfrac%7B2%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%7B2%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%7D%5C%5C%5C%5C%20%3D%202%5E%7B%5Cfrac%7B1%7D%7B2%7D-%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%20%3D%202%20%5E%7B%5Cfrac%7B3-2%7D%7B6%7D%7D%5C%5C%5C%5C%3D%202%5E%7B%5Cfrac%7B1%7D%7B6%7D%7D%5C%5C%5C%5C%3D%20%5Csqrt%5B6%5D%7B2%7D)

Answer:
x ≈ 18.9
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° =
=
( multiply both sides by 20 )
20 × cos19° = x , then
x ≈ 18.9 ( to the nearest tenth )
