The absolute change is expressed as a positive percentage here, which would be 49.53%. The relative change would be the same answer, only negative since the amount is going down.
In order to find the percentage of change, you would subtract the new total from the previous total and then divide by the previous.
49.53%
The bacteria would double every 20 minutes, so before then is when the bacteria is still in its singular form before it doubles.
Answer:
it would be negative you subrtract not add , the answer is -7.52
Step-by-step explanation:
Complete question is;
Andrea is given ABC and told that a² + b² = c². She draws right triangle RTS with legs measuring a and b and hypotenuse measuring 2. Which best describes what Andrea should
do in order to prove that ABC is a right triangle?
Answer:
Andrea should show that c = 2, so: ∡ABC = ∡RTS and ∡C = ∡S. Hence, ∡C is a right angled triangle, hence ΔABC is a right triangle
Step-by-step explanation:
In this question, we are told that the given sides of the triangle are a, b and c. Now, Andrea is able to draw the two sides of the right triangle with sides = a and b and the third, hypotenuse equal to 2. Since the length of the hypotenuse = 2, then we have;
2² = a² + b²
However, we are told that c² = a² + b²
Therefore, c = 2
Hence, Andrea should show that c = 2 so ΔABC = ΔRTS and ∡C = ∡S hence ∡C is a right angled triangle since it is the angle opposite to the hypotenuse c and therefore, ΔABC is a right triangle.
Just add $1.25 to $4.75 till you get up to $9.75 and count how many times you added $1.25 which should be 4 times
