A paved walkway around a garden has an outer diameter of 80 ft and an inner diameter of 40 ft. A diagram is shown below.

k0ka [10]

Given:

Outer diameter = D = 80 ft
Inner diameter = d = 40 ft

So,

Outer radius = R = D/2

=> R = (80 ft)/2

=> R = 40 ft

Inner radius = r = d/2

=> r = (40 ft)/2

=> r = 20 ft

Area of paved pathway = πR² - πr²

= π(R² - r²)

= π(R + r)(R - r)

= π(40 + 20)(40 - 20) ft²

= π(60)(20) ft²

= 3.14 * 1200 ft²

= 3768 ft²

Kevin has 16 ounce can of mixed nuts he gives 1/2 of the mixed nuts to his sister. He then eats 3/4 of the remaining nuts. How m

mixas84 [53]

Kevin will be left with 2 ounces of mixed nuts in the can

Step-by-step explanation:

Given

Total nuts = 16 ounces

As Kevin gave 1/2 of the nuts to his sister, he will be left with

$= \frac{1}{2} * 16\\= 8$

He is left with 8 ounces of mixed nuts

The he eats 3/4 of the remaining

$= \frac{3}{4} * 8 \\= 6\ ounces$

so he is left with 8 - 6 = 2 ounces of mixed nuts

Hence

Kevin will be left with 2 ounces of mixed nuts in the can

Find the value of (x+5) (x+2)+(x-3) (x-4) in its simplest form. What is the numerical value when x = -6?

Alex777 [14]

Answer:

$( - x + 5)(x + 2) + (x - 3)(x - 4)$

where as; x = - 6

<u>Solution</u>

<u> $(x + 5)(x + 2) + (x - 3)( x - 4)$ </u>

<u> $( - 6 + 5)( - 6 + 2) + ( - 6 - 3)( - 6 - 4)$ </u>

<u> $(- 1)( - 4) + ( - 9)( - 10)$ </u>

<u> $4 + 90$ </u>

<u> $94$ </u>

The answer is 94.
