Explain why 3/4 of 16 is the same as 3x16 divided by four?

kolbaska11 [484]

Its not. because 16 / .75 (which is 3/4) = 21.33--

3 * 16 = 48 / 4 = 12

I hope this helps :)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (11, 4) → x₁ = 11, y₁ = 4

Point (5, 8) → x₂ = 5, y₂ = 8

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(5-11)^2+(8-4)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-6)^2+(4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{36+16}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$

a boat takes 4 hours to go 20 miles upstream.It can go 32 miles downstream in same time.Find the rate of the current and the rat

Zinaida [17]

Let

x---------> the rate of the boat in still water in mph

y--------> the rate of the current in mph

we know that

Upstream

$rate=\frac{20}{4} \\\\ rate=5mph$

$x-y=5$ equation $1$

Downstream

$rate=\frac{32}{4} \\\\ rate=8mph$

$x+y=8$ equation $2$

Adds equation $1$ and equation $2$

$x-y=5\\ x+y=8\\ -----\\ 2x=13\\ x=6.5mph$

Find the value of y

$x+y=8\\ y=8-x\\ y=8-6.5\\ y=1.5 mph$

therefore

the answer is

the rate of the boat in still water is $6.5 mph$

the rate of the current is $1.5 mph$

If n is a whole number, and 0.01 is between 1/n and 1/n+2, what is the value of n?

OLga [1]

The value of n is 99

Integers are the set of numbers including all natural numbers and 0. They are part of the real numbers that do not include fractions, decimals, or negative numbers. Counting numbers are also considered whole numbers.

Natural numbers together with zero (0) are referred to as whole numbers. We know that natural numbers refer to the set of counting numbers starting from 1, 2, 3, 4 and so on. Simply put, integers are a set of numbers without fractions, decimals, or even negative integers. It is a collection of positive integers and zero. Or we can say that integers are the set of non-negative integers.

Integers are the set of natural numbers togethe with the number 0. In mathematics, the set of integers is given as {0, 1, 2, 3, ...}, denoted by the symbol W.

W = {0, 1, 2, 3, 4, …}

All natural numbers are integers.

All integers are real numbers.

It is given that If n a whole number, and 0.01 is between 1/n and 1/n+2, then we need to find the value of n.

1/n+2 < 0.01 < 1/n

1/n+2 < 1/100 < 1/n

n< 100 < n +2

Put n = 99, then we get

99 < 100 < 101

Hence the value of n is 99.

What is the equation in point-slope form of the line passing through (0,6) and (1,3)

NISA [10]

Answer:

$y = -3x+6$

Step-by-step explanation:

Coordinates are (0,6) and (1,3)

Slope = $\frac{rise}{run}$

Slope = $\frac{3-6}{1-0}$

Slope = -3

Now, Finding b

Taking any Point

Point = (x,y) = (0,6)

So, x = 0, y = 6

Putting in slope-intercept form to find b

$y =mx+b$

=> 6 = (-3)(0)+b

=> b = 6

Now Putting slope and b in the formula to get the required slope-intercept form.

$y =mx+b$

=> $y = -3x+6$
