H (4.84) will be the correct answer

Answer: You are correct. The answer is choice (H) 4.84

======================================================

Explanation:

10% = 10/100 = 0.1

10% of 4.4 = 0.1*4.4 = 0.44

Increasing 4.4 by 10% means we add on 0.44 to get 4.4+0.44 = 4.84

So the ruler says 4.4 inches but the actual table could be as long as 4.84 inches.

---------

A shortcut is to compute it like this:

4.4*1.1 = 4.84

The multiplier 1.1 represents an increase of 10% because

1.1 = 1 + 0.1 = 100% + 10%

This shortcut allows for multiple percentage increases that can be chained together fairly quickly.

Answer:

I think there must be g(x) instead of 8(x) in the question. You can look the solution but i have corrected it and then solved it.

Solve the quadratic equation: 3x2 + x - 5 = 0

Yuri [45]

Hey there!

$3x^2 + x -5 = 0$

This equation is in standard form, which is $ax^2+bx+c=0$ .

We are going to solve this with the quadratic equation, so we need to find the values for a, b, and c in the given equation. We can just look at it and identify the variables.

a = 3, b = 1, c = -5

Let's plug these values into the quadratic equation:

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$x=\frac{-1\pm\sqrt{1^2-4(3)(-5)} }{2(3)}$

Multiply 4(3)(-5) together and multiply 2(3). Square 1.

$x=\frac{-1\pm\sqrt{1+60} }{6}$

Add 1 and 60.

$x=\frac{-1\pm\sqrt{61} }{6}$

This is our answer in exact form. If you need this as an approximate value, let me know and I will do that for you.

Hope this helps!

Al and Bill each have two bullets. They fire alternately at a glass bottle. Al has hitting probability 1/3 and Bill 1/4. What is

enot [183]

P(Al hits bottle first time) = 1/3
P(Al misses the first shot but hits on his second shot) =
P( Al misses and bill misses and Al hits) = 2/3 * 3/4 * 1/3 = 1/6

So required probability = 1/3 + 1/6 = 1/2
