Im going to assume that 3√ is √3

And √3 is irrational because You cant square root it without getting nuked with a Random Number generator of decimals.

Linn is making cookies. Each batch of cookies

Answer:

4 cups of sugar require 14 cups of sugar

Step-by-step explanation:

Given

$\frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar$

Required

Determine the cups of flour for 4 cups of sugar

First, we need to determine the unit rate for 1 cup of sugar.

This is done by multiplying both sides by 4

$4 * \frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar * 4$

$\frac{7}{2}\ cup\ flour = 1\ cup\ sugar$

Next, we determine cup of flour for 4 cups of sugar.

This is done by multiplying both sides by 4

$4 * \frac{7}{2}\ cup\ flour = 1\ cup\ sugar * 4$

$2 * 7\ cup\ flour = 4\ cup\ sugar$

$14\ cup\ flour = 4\ cup\ sugar$

<em>Hence;4 cups of sugar require 14 cups of sugar</em>

Let FS R be a finite set. (a) Prove that F is closed (b) Prove that every point in F is an isolated point.

Lorico [155]

Answer:

a) Suppose that F is ordered in ascending order: $F = \{x_1,\ldots, x_n\}$ . Then, the complement of F can be written as

$F^c = (-\infty,x_1)\cup (x_1,x_2)\cup (x_2,x_3)\cup \cdots \cup (x_{n-1}, x_{n})\cup (x_n,+\infty)$

which is the union of a finite number of open intervals, then $F^c$ is an open set. Thus, F is a closed subset of the real numbers.

b) Take an arbitrary element of F, let us say $x_k$ . Now, choose a real number $\epsilon$ such that

$0$ there are not other element of F, because $\epsilon$ is less that the minimum distance between $x_k$ and its neighbors.

In case that $k=1$ we only consider $0$ , and if $k=n$ we only consider $0$ .

Then, all points of F are isolated.

Factor the denominator
x^2+3x-10
(x+5)(x-2)

(x-2)/((x+5)(x-2))

The x-2 in the numerator and denominator cancel out.

Final answer: x+5

A school replaced 20% of it computers with new ones . what the total number of computers in the school if 55 computers were repl

sladkih [1.3K]

The total is 275 because 100% divided by 20% is 5 and if 20%= 55 then that means that 55 goes into 100% 5 times so you multiply 55 by 5 to get 275. Hope I helped! Please rate me as the brainliest!
