What is 50.24 rounded to the nearest tenth

2 answers:

4 0

50.24 rounded to the nearest tenth is 50.2
Since the 4 is less than 5, it can't round the 2 up to 3. The 2 would stay the same.

Allan and Dave bowl together and their combined total score for one game was 375 points. Allan’s score was 60 less than twice Da

Bess [88]

A system of equations is:
B )
x + y = 375
x = 2 y - 60
We will solve this system:
2 y - 60 + y = 375
3 y = 435
y = 435 : 3
y = 145
x = 375 - 145
x = 230
Allan`s score was 230 and Dave`s score was 145.

S(t) = -16t^2+96t+256 the quadratic function models the balls height above the ground, s(t), in feet, t seconds after it was thr

Vaselesa [24]

Answer:

The ball reaches maximum height in 3 seconds.

The maximum height of the ball is of 400 feet.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

$f(x) = ax^{2} + bx + c$

It's vertex is the point $(x_{v}, f(x_{v})$

In which

$x_{v} = -\frac{b}{2a}$

If a<0, the vertex is a maximum point, that is, the maximum value happens at $x_{v}$ , and it's value is $f(x_{v})$

In this question:

The height is modeled by:

$s(t) = -16t^2 + 96t + 256$

So, the coefficients are:

$a = -16, b = 96, c = 256$

Instant of time the ball reaches maximum height:

$t_{v} = -\frac{96}{2(-16)} = -\frac{96}{-32} = 3$

The ball reaches maximum height in 3 seconds.

What is the maximum height of the ball?

This is s(3).

$s(3) = -16t^2 + 96t + 256 = -16*3^2 + 96*3 + 256 = 400$

The maximum height of the ball is of 400 feet.
