RideAnS [48]3 years ago

0.40 is actually 2/5.

2/5=4/10=8/20=16/40

How did I create all of these fractions?

Quite simple... I multiplied each fraction by 1... What do you mean?

2/5*2/2=4/10

2/2 is one by the way.

4/10*2/2=8/20.

You get the idea?

How do i find the equation of the line?
Cerrena [4.2K]

Answer:

10x + 7y = 2

Step-by-step explanation:

Slope = (6 + 4)/(-4 - 3) = -10/7

Equation:

y + 4 = -10/7(x - 3)

7(y + 4) = - 10(x - 3)

7y + 28 = -10x + 30

10x + 7y = 30 - 28

10x + 7y = 2

A golfer hits a ball from a starting elevation of 4 feet with a velocity of 70 feet per second down to a green with an elevation
mafiozo [28]

Answer:

t = 4.5 seconds

Step-by-step explanation:

It is given that, a golfer hits a ball from a starting elevation of 4 feet with a velocity of 70 feet per second down to a green with an elevation of −5 feet.

The number of seconds t it takes the ball to hit the green can be represented by the equation as follows :

-16t^2 + 70t + 4 = -5\\\\-16t^2 + 70t + 9=0......(1)

We need to find time taken by the ball to land on the green. Solving the quadratic equation (1) we get :

t = -0.125 s and t = 4.5 s

Ignoring t = -0.125 s, we get the time taken by the ball to land on the green is 4.5 seconds.

The product of three positive integers is 300. If one of them is 5, what is the
Elan Coil [88]

Answer and Step-by-step explanation:

So, we are told that 3 positive integers multiply to be 300, and that one of the integers is 5.

First, we divide 300 by 5.

The result is 60.

Now, we take different (reasonable) numbers that add to 16:

10 and 6

12 and 4

We can see here that 10 and 6 are the integers because they add up to 16 and multiplies to 60.
