1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
EXPLANATION: (2x6)-10)+2(4x13+(12-20)
ANSWER: (20x14)=280 thats what i got lmk if its incorrect
The correct answer is a translation.
A rotation would change the direction, a reflection would change the direction, and a dilation would change the size.
I hope this helps :)
4.8
To find the answer, cross multiply 2/25 with x/60
2 times 60 is 120, so put 120 over 25 and divide for your answer.
Answer:
Option (4)
Step-by-step explanation:
m(∠PZR) = 
Radius of the circle = 8
Since, length of an arc = 
Here, θ = Central angle in radians
From the given formula,
m(arc PR) = 
= 
= 
Therefore, Option (4) will be the correct option.
