The manager could perform scalar multiplication on Matrix A, using the scalar 1.15.
Increasing the price by 15% would mean we are taking 100% of the value + another 15%; 100+15 = 115%; 115% = 115/100 = 1.15.
Multiplying every value in Matrix A by 1.15 will give the price raised by 15%.
Katie is 6; Cathy is 18!
X- Katie’s age now and 3x -Cathys age now
In 6 years, Katie is 12 and Cathy is 24.
2 x (X+6) = 3x + 6
2x + 12 = 3x + 6
6 = x
Answer:
FA = 25.87
Step-by-step explanation:
Given: BD = 30 , DF = 5 , EF = 16
To find: FA
Rectangular box is a Cuboid.
Figure attached.
AB = FE = 16
So,
In ΔADB
using Pythagoras theorem,

Again using Pythagoras theorem in Δ ADF we get

Therefore, FA = 25.87
