The Minnitte family pool, PQRS, measures 48 feet by 84 feet
48 : 84 = 4 : 7
The Gaudet family pool, WXYZ, measures 40 feet by 70 feet
40 : 70 = 4 : 7
The two pools are similar
The similarity statements :
PQ/WX = QR/XY = RS/YZ = PS/WZ
Scale factor:
48/40 = 6/5
84/70 = 6/5
So
SF = 6/5
Answer:
Step-by-step explanation:
We want to evaluate
We have a power to evaluate.
The base is 3
The exponent is 4.
What this means it's to multiply the base by itself four times
In general, if you have aⁿ , you multiply 'a' by itself n-times.
70/x=100/120
(70/x)*x=(100/120)*x - we multiply both sides of the equation by x
70=0.833333333333*x - we divide both sides of the equation by (0.833333333333) to get x
70/0.833333333333=x
84=x
x=84
now we have:
