What is negative 9 plus 16/7

Mathematics

Answer:

negative 6 5/7

Step-by-step explanation:

16/7 would convert to 2 2/7. When you add -9 + 2 2/7 you add whole numbers first then fractions. -9 + 2 equals -7. From here you need to fill in the left over fraction by taking from the -7 itself. That's where you get your 5/7 froms, because you are adding 2/7 and 5/7 to get one, which in turn that 1 subtracts from 7 to get -6.

Step-by-step explanation:

-9 + 16/7 = ?

First, find out what 16/7 would make in decimal form, by dividing 16 by 7 (Use a calculator if needed)

16 / 7 = 2.3 (In estimation)

So, now you have ' -9 + 2.3 '

= -6.7

Answer:

The ball shall keep rising tills its velocity becomes zero. Let it rise to a height h feet from point of projection.

Step-by-step explanation:

Let us take the point of projection of the ball as origin of the coordinate system, the upward direction as positive and down direction as negative.

Initial velocity u with which the ball is projected upwards = + 120 ft/s

Uniform acceleration a acting on the ball is to acceleration due to gravity = - 32 ft/s²

The ball shall keep rising tills its velocity becomes zero. Let it rise to a height h feet from point of projection.

Using the formula:

v² - u² = 2 a h,

where

u = initial velocity of the ball = +120 ft/s

v = final velocity of the ball at the highest point = 0 ft/s

a = uniform acceleration acting on the ball = -32 ft/s²

h = height attained

Substituting the values we get;

0² - 120² = 2 × (- 32) h

=> h = 120²/2 × 32 = 225 feet

The height of the ball from the ground at its highest point = 225 feet + 12 feet = 237 feet.
