Answer:
60 kilometers per hour.
420 kilometers will be covered
Step-by-step explanation:
speed = distance ÷ time.
so 60kmh = 240km divided by 4 Hours
60km = 1 Hour of distance
240km = 4 Hours of distance
Therefore 60 x 3 hour is 180km added to 240 is 420km. So in 7 hours traveling 60 kilometers per hour the will cover 420kms.
First multiply each term by 24(the common denominator found by 8×3) to remove the fractions and make things easier.
This will give you,
Then just continue to simplify and isolate the variable.
In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.
Answer:
706.95in²
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder
Step one
The trash can has a cylindrical shape
The distance from the center to the edge is the radius r= 15in
Step two
Area of top (circular ) = πr²
A= 3.142*15²
A= 3.142*225
A= 706.95in²
Answer:
4.58 ft
Step-by-step explanation:
Pythagoras Theorem:
a^2 +b^2 = c^2
b^2 = c^2 - a^
b^2 =11^2 - 10^2
b^2 = 121 - 100
b^2= 21
the heigh = √21 = 4.58
Answer: 4.58 ft
