Charlie reads quickly. He reads 1\dfrac371 7 3 1, start fraction, 3, divided by, 7, end fraction pages every \dfrac23 3 2 st

OLEGan [10]

<h2>Answer:</h2>

The number of pages he will read in one minute is:

$2\dfrac{1}{7}\ \text{pages}$

<h2>Step-by-step explanation:</h2>

It is given that:

Charlie reads $1\dfrac{3}{7}\ \text{pages}$ in every $\dfrac{2}{3}\ \text{minutes}$ .

We know that:

$1\dfrac{3}{7}=\dfrac{10}{7}$

This means that:

Charlie reads $\dfrac{10}{7}\ \text{pages}$ in every $\dfrac{2}{3}\ \text{minutes}$ .

This means that:

$\text{In}\ \dfrac{2}{3}\ \text{minutes he reads}\ \dfrac{10}{7}\ \text{pages}\\\\\text{Hence}$

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{\dfrac{10}{7}}{\dfrac{2}{3}}\ \text{pages}$

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{10\times 3}{7\times 2}\ \text{pages}$

Hence,

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}$

Hence,

$\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}$

$\text{In}\ 1\ \text{minute he will read}\ 2\dfrac{1}{7}\ \text{pages}$

1.) Give five (5) examples of quadratic equations written in standard form. Identify the values of a, b, and c in each equation.

Kitty [74]

<h3>NUMBER 1:</h3>

1.) Give five (5) examples of quadratic equations written in standard form. Identify the values of a, b, and c in each equation.

a. 3 + x² = - 6x

Standard form: x² + 6x + 3 = 0

a, b, and c: a = 1, b = 6, c = - 3

b. x² - 3x = 18

Standard form: x² - 3x - 18 = 0

a, b, and c: a = 1, b = - 3, c = -18

c. 3 + 2x² = 6

Standard form: 2x² - 3 = 0

a, b, and c: a = 2, b = 0, c = -3

d. 3x + 2x² = 7

Standard form: 2x² + 3x - 7 = 0

a, b, and c: a = 2, b = 3, c = -6

e. x² + 8x = - 8

Standard form: x² + 8x + 8 = 0

a, b, and c: a = 1, b = 8, c = 8

<h3>NUMBER 2:</h3>

2.) Name three (3) objects or cite three (3) situations in real life where quadratic equations are illustrated. Formulate quadratic equations out of these objects or situations then describe each.

1 and 2.) A company is going to make frames as part of a new product they are launching. The frame will be cut out of piece of steel, and to keep the weight down, the final area should be 28 cm². The inside of the frame has to be cm by 6cm.

Area of steel before cutting :

= (11 + 2x) × (6 + 2x) cm²
= 66 + 22x + 12x + 4x²

Quadratic Equation = 4x² + 34x + 66

Area of steel after cutting out the 11 × 6 middle :

= 4x² + 34x + 66 - 66

Quadratic Equation = 4x² + 34

3.) A ball is thrown straight up, from 3m above the ground, with a velocity of 14 m/s.

Add them up and the height(h) at any time(t) is :

h = 3 + 14t - 5t²

Quadratic Equation = -5t² + 14t + 3 = 0
