Well first you have to figure out how many feet are in a yard. Answer is 3 then minus 3/4 or 75% which will give you 2.25 feet. Then do
1 / 2 of (2.25 feet) = 1.125 feet.
Catalyst is a substance that speeds up the rate of any chemical reaction but they do not take part in the reaction.
<h3>What is a catalyst</h3>
Catalyst is a substance that speeds up the rate of any chemical reaction but they do not take part in the reaction.
Catalysis is the process of increasing the rate of a chemical reaction by the addition of a substance known as a catalyst.
Catalysts are known not to be consumed in the reaction and remain unchanged at the end of a reaction

Answer:
A scale factor of 2
Step-by-step explanation:
Answer:
About 20%
Step-by-step explanation:
The probability of a point on the un-shaded region will be given by;
Area of the shaded region/total area
Considering that the circles are of the same size, then the length of the square is 2d
Area of the square = 4d²
Area of the shaded = (4d² -4π(d/2)²
= 4d² -πd², but π = 22/7
= 6/7d²
Probability = (6/7d² ÷ 4d²) × 100%
= (6/28 d²) × 100%
= 21.42 %
So your answer is B. 20%
Don't thank me this was easy.
