Answer:
You will need 2 cups of butter.
Step-by-step explanation:
There are 2 ways to figure this out.
#1. If you need 4 cups of flour, then you will need 2 cups of sugar.
If you need 2 cups of sugar, then you will need 1 cup of butter.
Which means that if you double the recipe you will need 2 cups of butter.
#2. If you are doubling the recipe, then you will need 8 cups of flour.
Which means you will need 4 cups of sugar.
And you will need 2 cups of butter!
I hope this helps! :)
Answer:
Yes, he made an error in Step 3. He should have subtracted 2 from both sides.
Step-by-step explanation:
The coefficient of thermal expansion of the metal will be 1.4 x 10⁻⁵ °c.
<h3>What is thermal expansion?</h3>
Every material has its property of contraction or expansion by the change of temperature. The expansion and contraction of any material are indicated by a coefficient this coefficient is called the coefficient of thermal expansion.
Here we have the following data:-
l₁= 1.000 m
l₂ = 1.001 m
Δ = 70° C
The formula for calculating the coefficient of linear expansion will be:-

By putting the values we will get the answer.

Therefore the coefficient of thermal expansion of the metal will be 1.4 x 10⁻⁵ °c.
