Answer:
the scenic route take 6h 40m
Step-by-step explanation:
first we have to make an equation that represents the relationship of each route
x = scenic route
y = direct route
x = y + y * 25/100
now we have to make an equation that represents the routes over time
x + y = 12
we replace the x by what is the same in the first equation (y + y * 25/100) in the second equation
x + y = 12
(y + y * 25/100) + y = 12
2 y + 0.25 y = 12
2.25y = 12
y = 12/2.25
if we spend this in minutes multiplying it by 60
y = 12/2.25 * 60 = 320 m = 5h 20m
x + y = 12
x + (5h 20m) = 12h
x = 12h - 5h 20m
x = 6h 40m
Answer:
The formula of the volume of a cylinder is known as follow
<h2>V= πr²h</h2>
Where
π is 3,14 or 22/7.
d (diameter) is a straight line segment that crosses a center and connects two points on the circle.
r is the radius of the to part of the cylinder.
h is the height.
we can subsitute to our formula knowing that
d = 4cm (turn to r = <em>2cm</em>,because the formula use r) ; h = 11cm
V = πr²h
= 3,14 × 2² × 11
= 3,14 × 4 × 11
= 3,14 × 44
= 138,16 rounded off (138,2cm3) result
43 is the value of x Cox it's an angle on a straight line
Lance invited 36 people to his party.
<u>Step-by-step explanation:</u>
It is given that,
- Lance bought 12 quarts of lemonade.
- Everyone who came to his party could have exactly 1/3 quart.
We know that,
The total quarts of lemonade available for the party = 12
Each person in the party consumes = 1/3 quart.
We need to find out how many people did Lance invited to his party.
<u>To find the number of people :</u>
Let us consider 'x' be the number of people invited to the party.
Total lemonade = number of people × lemonade for each person.
⇒ 12 = x × 1/3
⇒ 12×3 = x
⇒ x = 36 people
Therefore, Lance invited 36 people to his party.
