Answer: $13.75
Step-by-step explanation:
Since Mrs. Chin paid a 20 percent tip on the bill for lunch and the tip amount was $2.75, then the bill for lunch before the tip was added to it will be calculated thus:
Let the bill for lunch be represented by x. Therefore,
20% of x = $2.75
20/100 × x = $2.75
0.2 × x = $2.75
0.2x = $2.75
x = $2.75/0.2
x = $13.75
Therefore, the bill is $13.75 before the too was added.
Hello!
The formula for percentage increase is:
Percent Increase = {( New Value - Old Value) / Old Value × 100}
Substitute = {( 566.60 - 550) / 550 × 100]
Solve:
566.60 - 550 = 16.6
16.6 / 550 = 0.0301818182
0.0301818182 × 100 = 3.0181818182
You may round that to 3.1%
So, Mr. Dawkins' salary increased by about 3.1%
Answer:
a=18.7 or 19 rounded up
Step-by-step explanation:
Use Pythagoras Thereom
a^2=8^2+17^2
a^2=64+289
a^2=353
√353
a=18
To determine the time it will take for the diver to reach the water below, we derive the equation such that t will be our unknown and that will be,
t = √(d/4.9)
Substituting the known values,
t = √(70 m / 4.9) = 3.78 s
Therefore, it will take the diver approximately 3.78 seconds to reach the water below.
