Answer:
Step-by-step explanation:
Given,
The number of litres consumed by car in (x+20) km = 6,
So, number of litres consumed by car in 1 km = 
,
Now, number of litres consumed by car in 100 km = 100 × litres consumed by car in 1 km
Hence, the rate of fuel used by his car would be 
litres per 100 km.
Answer:
The length of x in #1 is 15.57
Step-by-step explanation:
Let's use #1 as an example to teach show you how to do this. In a right triangle we can solve these using trig. In this particular one, we have the measure adjacent to the angle and we are looking for the one opposite of the angle. So we look at all the trig functions and select the one that uses both of those two terms.
Sinα = Opp/Hyp
Tanα = Opp/Adj
Cosα = Adj/Hyp
As you can see, Tan is the function we are looking for. So we plug in all known information into that equation.
Tanα = Opp/Adj -----> Plug in known values
Tan(60) = x/9 ----->Calculate out the trig function
1.73 = x/9 -----> Multiply by the denominator to solve
15.57 = x
In order to know that, you need to divide 7 from 4730
It would be: 4730/7 = 675.71
So, your final answer is 675.71
Hope this helps!
Answer:
Step-by-step explanation:
Patrick pizza parlor is famous for its giant circular pizza, which has an area of 1519.76 square inches. The pizza is circular in shape. The formula for determining the area of a circle is expressed as
Area = πr^2
π is given as 3.14
Therefore,
1519.76 = 3.14 × r^2
r^2 = 1519.76/3.14 = 484
Taking square root of both sides of the equation, it becomes
r = √484 = 22 inches
Diameter = 2 × radius.
Therefore, the diameter of the giant pizza is 2 × 22 = 44 inches
