Answer:

x = 19
x = 34
x = 39

Step-by-step explanation:

1. A right angle has a measure of 90°. The whole is the sum of the parts.

(2x +3)° +49° = 90°

2x +52 = 90 . . . . . . . . divide by °, collect terms

2x = 38 . . . . . . . . . . . . subtract 52

x = 19 . . . . . . . . divide by 2

2. A linear pair measures 180°. The whole is the sum of the parts.

(x -5)° +151° = 180°

x +146 = 180 . . . . . . . divide by °, collect terms

x = 34 . . . . . . . . .subtract 146

3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.

64° +(3x -1)° = 180°

3x +63 = 180 . . . . . . . divide by °, collect terms

3x = 117 . . . . . . . . subtract 63

x = 39 . . . . . divide by 3

onsider the following problem: A box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutti

Sholpan [36]

Answer:

V (max) = 2 ft³

and x side of the base is x = 0,5 feet

Step-by-step explanation: See annex ( two different cubes)

We have a square piece of cardboard of 3 inches wide

Let x be lenght of side to cut in each corner

Then the base of the (future cube) is 3 - 2x, and the area is

( 3 - 2x )²

And the height is x Then volume of the cube as a function of x is:

V(x) = ( 3 - 2x )² *x or V(x) = ( 9 + 4x² - 12x )*x

V(x) = 4x³ - 12x² + 9x

Taking derivatives on both sides of the equation

V´(x) = 12x² - 24x + 9

V´(x) = 0 12x² - 24x + 9 = 0 simplifying 4x² - 8x + 3 = 0

Second degree equation solving for x

x₁,₂ = [ 24 ± √( 576) - 432 /24

x₁,₂ = [24 ±√144 ]/24

x₁,₂ = ( 24 ± 12) /24 x₁ = 1.5 feet x₂ = 0,5 feet

Of these two values we have to dismiss x₁ because if x = 1.5 we don´t have a cube ( 0 height )

Then we take x = 0,5 feet

And

V (max) = (2)²*0,5 = 4*0,5

V (max) = 2 ft³

Faiz's total online shipping bill comes to £45.71.

larisa [96]

Given:

Faiz's total online shipping bill comes to £45.71.

He then receives discount of £15.90.

To find:

How much does he have to finally pay after the discount?

Solution:

We have,

Amount of bill = £45.71

Discount amount = £15.90

Now,

Final payment = Amount of bill - Discount amount

= £45.71 - £15.90

= £29.81

Therefore, Faiz's have tp pay £29.81 after discount.

At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 fr

nadezda [96]

Answer:

An equation in the slope-intercept form is:

$y = 15x+210$

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where m is the rate of change or slope and b is the y-intercept

Given

Let x represent the time in months

Let y represent the amount of money remaining in the account.

Given that every month Monica withdraws $15 from this account for her contact lenses

so, the rate of change or slope = m = 15

Given that after 3 months she has $255 left in her account.

i.e. (3, 255)

substituting $m = 15$ , $x = 3$ and $y = 255$ in the slope-intercept form to determine the y-intercept

$y = mx+b$

$255 = 15(3) + b$

switch sides

$15(3) + b = 255$

$45 + b = 255$

$b = 255 - 45$

$b = 210$

Thus, the y-intercept b = 210

Now, substituting $m = 15$ and $b = 210$ in the slope-intercept form of the line equation

$y = mx+b$

$y = 15x+210$

Hence, an equation in the slope-intercept form is:

$y = 15x+210$
