Find the surface area of a cone with a slant height of 18 inches and a radius of 7 inches

Answers

Answer 1

Answer: Please see the pic, I'd solved in it.

Answer 2

Answer: The surface area formula of a cone is:
=Area of base × $(1)/(2)$ × perimeter of base × slant height
= $\pi$ r² + $\pi$ rl
= $\pi$ (7)² + $\pi$ (7)(18)
=49 $\pi$ + 126 $\pi$
=175 $\pi$ in² (in terms of $\pi$ )
=549.7787 in²
≈ 550 in²

Fresh pond has a population of 854 and it’s increasing by 3 people per year. Strawberry has a population of 427 and it’s increasing by 10 people per year. In how many years will the two villages have the same number of residents?

Answers

Answer:

The number of years that will the two villages have the same number of residents is 61 years

Step-by-step explanation:

Let's assume number of years as 'x'

First Pond:

Fresh pond has a population of 854

and it’s increasing by 3 people per year

so, we can find equation for population of first pound

$P=854+3x$

Second pond:

Strawberry has a population of 427

and it’s increasing by 10 people per year

so, we can find equation for population of first pound

$P=427+10x$

Since, populations are equal

so, we can set both equation equal and then we can solve for x

$P=427+10x=854+3x$

$427+10x=854+3x$

$7x=427$

$x=61$

So,

The number of years that will the two villages have the same number of residents is 61 years

How do you do that plz help or just give the answer

2x-(-1/2x-1/2)=8
the - sign before the first parentheses is a negative 1
you distribute the -1 into the parentheses
-1 multiplied by -1/2x is 1/2x and -1 multiplied by -1/2 is 1/2.
so now we have 2x-1/2x+1/2=8
you combine like terms (2x and -1/2x)
you get 1 1/2x+1/2=8
you subtract the 1/2 to get 1 1/2x= 7 1/2
you divide everything by 1 1/2.
the answer is x=5

A man buys a book for $20 and wishes to sell it. What price should he mark on it if he wishes for a 40% discount and 50% profit on the cost price. Please explain your answer!

Answers

With that particular larcenous scheme in mind, he will price the book
regulaly at $50 .   See the price-tag in the attached picture.

With a regular price of $50 written all over it, he can run a spectacular,
once-in-a-blue-moon, "40%-off" sale.

   40% of $50 = 0.4 x $50 = $20 off

   $20 off of $50 ===> Sale price = $30 is what the buyer will pay
during the spectacular sale.

Then, the sale price of $30 is (30/20) = 1.50 of his own original cost.

1.50 of his own cost means 0.50 = 50% more than he paid for it.
