Answer:

x ≈ 2.3 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos55° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{4}$ ( multiply both sides by 4 )

4 × cos55° = x , thus

x ≈ 2.3 cm ( to 1 dec. place )

Recipe asks for 4 1/2 pounds of chicken

ohaa [14]

Since a whole recipe asks for 4 1/2 pounds of chicken, then for a 1/2 recipe, you divide 4 1/2 by 2.

It’s easier to turn 4 1/2 to 4.50

4.50/2 = 2.25 or 2 1/4

You need 2 1/4 pounds of chicken for 1/2 of a recipe.

If you know that 84 is 70% of the whole, explain how you can use proportional reasoning to determine the whole. Use the drop-dow

Akimi4 [234]

Answer: The value of whole is 120.

Step-by-step explanation:

Since we have given that

84 is 70% of the whole.

Let the whole be 'x'.

According to question, it becomes,

$84=\dfrac{70}{100}\times x\\\\84=0.7\times x\\\\\dfrac{84}{0.7}=x\\\\120=x$

So, we have use the proportion i.e. $\dfrac{84}{70\%}=\dfrac{84}{0.7}$ to determine the value of whole.

Hence, the value of whole is 120.
