Courtney reads around 110 words per minute. She procrastinated and now has less than a week to finish her reading assignment. If the book she needs to finish has another 820 pages left and each page has around 350 words, how many hours can Courtney complete her assignment?

Answers

Answer 1

Answer: 820 pages X 350 words = 287,000 words

287,000 / 110 = 2.609.09 minutes

2.609.09 / 60 = 43.48 hours

It would take about 2 days of non-stop reading to finish her assignment

Holly wants to add an odd number to 659. Which number could possibly be the sum?

Answers

1 is an odd number, therefore 660 (since 659+1=660) could possibly be the sum.

solve x^2-6x= -25

Answers

Answer: x = 3 ± 4i

Step-by-step explanation:

x² - 6x + 25 = 0

a=1 b= -6 c=25

Use Quadratic Formula:

$x = \frac{-b +/- \sqrt{b^(2)-4ac}}{2a}$

$= \frac{-(-6) +/- \sqrt{(-6)^(2)-4(1)(25)}}{2(1)}$

$= (6 +/- √(36-100))/(2)$

$= (6 +/- √(-64))/(2)$

$= (6 +/- 8i)/(2)$

$= (2(3 +/- 4i))/(2)$

= 3 ± 4i

Answer:

x= 3+4i , x= 3-4i

Step-by-step explanation:

x^2-6x= -25

To solve for x we need to make right hand side

So add 25 on both sides

$x^2-6x+25=0$

Now apply quadratic formula

$x=(-b+-√(b^2-4ac))/(2a)$

From the given equation a=1, b=-6 and c=25

Plug in all the values in the formula

$x=(-(-6)+-√((-6)^2-4(1)(25)))/(2(1))$

$x=(6+-√(-64))/(2)$

We know $√(-1) =i$

So equation becomes

$x=(6+8i)/(2)$

Divide by 2

x= 3+-4i

So x= 3+4i , x= 3-4i

Large chocolate bar has a base area of 48.96 square feet and its length is 0.6 foot shorter than twice its width. Find the length and width

Answers

The length and the width of the bar are 6.7ft and 7.3ft respectively

The formula for calculating the volume of the chocolate bar is expressed as:

V = Base area * height

Given the following parameters

Base area = 48.96 square feet

B = length * width

48.96 square feet = lw

If the length is 0.6 foot shorter than twice its width, hence;

l = w - 0.6

The expression becomes;

$48.96 = w(w-0.6)\n48.96 = w^2 - 0.6w\nw^2 - 0.6w - 48.96 - 0$

On factorizing the result, w = 7.3ft

Recall that l = w - 0.6

l = 7.3 - 0.6

l = 6.7ft

Hence the length and the width of the bar are 6.7ft and 7.3ft respectively.

Answer:

Length=9.6

Width=5.1

Step-by-step explanation:

Step one:

given data

for the large chocolate

Area=48.96ft^2

let the width be x

w=xft

let the length be l

l=(2x-0.6)

Step two:

we know that area A=length * width

48.96=(2x-0.6)*x

48.96=2x^2-0.6x

2x^2-0.6x-48.96=0

divide through by 2 we have

x^2-0.3x-24.48=0

solving the quadratic equation, the roots are

x=5.1

x=-4.8-----not correct cannot be -ve

so x=5.1

the width is 5.1

the length = 2(5.1)-0.6

l=10.2-0.6

l=9.6

check Area= 9.6*5.1= 48.96

Evaluate |x + y|, for x = 8 and y = -15.

Answers

First, we substitute the numbers to the corresponding variables.

|(8) + (-15)|

And we change the plus sign since we’re just basically subtracting.

|8 - 15|

|-7|

Now to do absolute values, we must remember that it will always equal a positive unless there is a negative sign outside of the | |.

So the final answer will be 7.
