i.e truch weighs 500 lbs so the car weighs 50lbs. lets say thw truck goes 2 mph so thatll be 1000 for the car to reach 1000 you have to divide and youll get 20. so the car has to be ten times as fast as the truck

Answer:

The car will have to   move 10 times greater than  the truck

Step-by-step explanation:

Let x be the mass of  car

Mass of truck=10x

We have to find how fast the  car will have to  move to have the same momentum as the truck when it moves.

We know that momentum=mass\times velocity

Momentum of car=x\times v_1

Where v_1=velocity of car

Momentum of truck=10x\times v_2

Where v_2=Velocity of truck

According to question

10x\times v_2=x\times v_1

v_1=10v_2

Hence, the car will have to   move 10 times  greater than the truck when both have same momentum

FIND THE GCF. Mathematics
Rom4ik [11]

The G.C.F of the given algebraic expression is; ⁴⁹/₆a xy

<h3>What is the G.C.F (Greatest Common Factor)?</h3>

The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6.

We are given the algebraic expression;

(3 x y * 4x²y * ¹/₁ * 5x³y ^ z * 4)7a * 1/1 * 7*6

Expanding this further gives;

⁴⁹/₆a((3xy * 4x²y * 20x³y ^ z )

Now, the GCF of the terms inside the bracket would be x y. Thus, expanding the GCF  we have;

⁴⁹/₆a xy((3 * 4x * 20x²y^(z - 1))
