What is the answer to 1/2-1/5

1 answer:

3 0

First you need to find the common denominator. Think of a number that both 2 and 5 can go in to evenly. 10 is the best number, so, make both denominators 10. What you do to the bottom, you must do to the top.
Now your equation is 5/10-2/10
Your answer is 3/10

An object is hanging by a string from your rearview mirror. While you are decelerating at a constant rate from 25 m/s to rest in

lidiya [134]

The rate of deceleration is equal to 25 m/s / 6 s = 25/6 m/s^2.

(a) The string should be angled in such a way that the horizontal acceleration is equal to 25.6 and the vertical acceleration is equal to gravitational acceleration. Using trigonometry,Angle from the vertical = arctan(25/6 / 9.8) = 23.03 degrees.

(b) Since the car is decelerating, one end of the string attached to the car is pulled back and because of the inertia of the object it is goes on the opposite direction and so the object moves toward the windshield.

Use the formula h=16t2, where t is time in seconds and h is the distance in feet traveled by a free-falling body or object to so

aksik [14]

Answer:

The time required is 15.97 second.

Step-by-step explanation:

Consider the provided information.

A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.

First find the distance between skywalk and canyon floor by using Pythagorean theorem.

Distance between skywalk and canyon's edge = $\sqrt{4080^2+90^2}$

Distance between skywalk and canyon's edge = $4080.99$

Substitute h = 4080.99 in the provided formula.

$4080.99=16t^2$

$t^2=255.062$

$t=15.97$

Hence, the time required is 15.97 second.

Assume that a watermelon dropped from a tall building falls y = 16t ^ 2 ft in t sec. Find the watermelon's average speed during

mojhsa [17]

Answer:

A.) 96 ft/sec

Step-by-step explanation:

to find the average speed of the watermelon's fall in 6 seconds, substitute 6 as t in the equation and then divide by 6: $y = \frac{16(6)^{2} }{6} = 96 ft/sec$
