A: 50 cookies an hour (seth) 80 cookies an hour (erika)
b: 50:1 80:1
c: Seth, he bakes more in an hour
we know that
if ∠UVW and ∠XYZ are complementary angles
then
∠UVW + ∠XYZ=90°
∠UVW=x-10
∠XYZ=4x-10
substitute the values
(x-10)°+(4x-10)°=90°
Solve for x
5x-20=90
5x=90+20
5x=110
x=22°
∠UVW=x-10=22-10=12°
∠XYZ=4x-10=4*22-10=78°
therefore
<u>the answer is</u>
x=22°
∠UVW=12°
∠XYZ=78°
Answer:
The price of a sandwich is £2.5 and the price of a croissant is £2
Step-by-step explanation:
Let s be the number of sandwiches and c be the number of croissants
Then according to given statements the equations will be:

Multiplying equation 1 by 2 and subtracting equation 2 from the new equation

Now

Putting s=2.5 in equation 1

Hence,
The price of a sandwich is £2.5 and the price of a croissant is £2
Answer:
To write a recursive formula you need to: First, determine if the sequence is geometric(For example, If your multiply, or divide, the same amount for one term or more). Next, Find the common ratio(In other words the number that you multiply or divide).
Step-by-step explanation:
Answer:
4 sets
Step-by-step explanation:
The greatest common factor (GCF) of 16 and 12 is 4. This is the largest number that evenly divides 12 and 16. It can be found by looking at the factors of those numbers:
12 = 4·3
16 = 4·4
Or it can be found by seeing if the difference of the numbers (4) evenly divides them both. It does, so that is the GCF.
