Answer:
All three statements are true
Step-by-step explanation:
A shipping fee of 5% is charged online with every item purchased online
First let's just take each option and calculate them based on this, to see if the answers matched
Keith buys a 40 dollar book
40 x 0.05 = 2
Therefore there will be a two dollar fee on Keith's book
40 + 2 =42
The first statement is true
A chair costs $80
80 x 0.05 = 4
80 + 4 = 84
The second statement is true
George buys a 20 dollar calculator
20 x 0.05 = 1
20 + 1 = 21
The third statements are true
All three statements are true
Answer:
sin X = 
cos X = 
tan X = 
Step-by-step explanation:
First, find what the hypothenuse is:
c = 30
sin x = 
cos x = 
tan x = 
The work done has the formula
W = F d
where the force and the displacement have the same direction
We can determine displacement using the distance formula
d = √[(5 - 0)² + (-1 - 4)²]
d = 5√2
Next, the force along the direction of the displacement must be determined
Use trigonometry to determine the angle θ
Finally, the work is calculated using the formula
W = F d / cos θ
substitute the values to get the answer
Answer:
12 years
Step-by-step explanation:
Given that
P = 5,600 e^0.0591
Reaching amount = 11,200
time period = t
We need to find out the time period i.e. t
So,
11,200 = 5,600 e^0.0591t
2 = e^0.0591t
Now take the log on both the sides
ln2 = 0.0591t ln
t = ln2 ÷ 0.059
= 0.693147÷ 0.059
= 11.748
= 12 years
8.5 * x = 5
5 / 8.5
Approximately 10/17
