you have this fraction...

\frac{42}{60}

simplify...

42/6=7
and
60/7=10

Thus...\frac{7}{10}

Thus, she has saved \frac{7}{10} of the money.

A 50. kg remote control car is accelerating on a flat road, and the free body diagram for the car is shown below. If the force o
goldfiish [28.3K]

Answer:

12 m/s²

Step-by-step explanation:

mass of the car = 50 kg

The net force applied to the car is 800 - 200 = 600 N

Form the Newton's second law:

F = m*a

where F is the net force applied to the object, m is the mass of the object, and a is the acceleration of the object.

Then, the acceleration of the car (in m/s²) is:

a = F/m

a = 600/50

a = 12 m/s²

A skyrocket is launched from a 30–foot-high platform, with initial speed 300 ft/s. If the polynomial −16t2 + 300t + 30 gives the
Stella [2.4K]

Answer:

566 ft

Step-by-step explanation:

Given the polynomial equation

-16t² + 300t + 30 = 0

We're asked to find how high the rocket would rise in a 2 second fuse rise. This is a simple instruction that can be obtained by setting the unknown, t, in the equation to 2. Doing this, we have

-16 * 2² + 300 * 2 + 30

-16 * 4 + 600 + 30

-64 + 630 = 566 ft

Then, we can therefore conclude that the rocket will rise high up to a distance of 566 ft

If AD=6 and AB=24, find AC
ruslelena [56]
When a perpendicular is dropped from the right-angle (C) to the opposite side AB, the metric relations apply:
BD*BA=a^2 ..........................(1)
AD*AB=b^2...........................(2)
BD*DA=DC^2........................(3)

Given AD=6, AB=24, using metric relation (2) above, we have
b^2=6*24=144
=>
b=sqrt(144)=12

By the way, we conclude that this is a 30-60-90 triangle because b/AB=(1/2)=sin(B) => B=30 degrees.

Answer: b=12
