Since 6/1.5 is 4. It increased 400%.
Answer:
There were 40 cups of coffee and 19 cups of tea sold.
Step-by-step explanation:
Total number of cups sold = 59
Let the number of tea cups = x
Let the number of coffee cups = y
Then, ------------------- (1)
Total amount collected = $108.50
=> -------------------- (2)
From (1), ------------------------ (3)
Substituting in (2):
=>
=>
=>
=>
Substituting in (3):
=>
find the ratio between the two triangles:
40 on the left corresponds to 50 on the right = 40/50 = .8
.8 is the fixed ratio between these two triangles.
to find x:
43 x .8 = 34.4
x = 34.4
"angles of similar triangles are always congruent."
a: 63
b: 88
c: 29
The slope is 0 because the y value doesn’t change meaning the slope is 0
