Leo is purchasing a bike that is on sale for 30% off. He knows the function that represents the sale price of his bike is c(p) = 0.7p, where p is the original price of the bike. He also knows he has to pay 12% sale's tax on the bike. The price of the bike with tax is f(c) = 1.12c, where c is the sale price of the bike.Determine the function that can be used to calculate the final price of Leo's bike by solving for f[c(p)].f[c(p)] = 1.82cp f[c(p)] = 1.82p f[c(p)] = 0.784cp f[c(p)] = 0.784p

What is the product of (3+radical 5) and (3-radical 5)

Answers

(3 + $√(5)$ ) × (3 - $√(5)$ )
Take the special case
(a - b)×(a + b)=a² - b²

a = 3
b = $√(5)$

3² - ( $√(5)$ )² {(√)² = the number itself}
9 - 5

(3 + √((5)) + (3 - √(5))

Ninth grade algebra.i am solving for x

Answers

Answer: x = 1

Step-by-step explanation:

So you need to get x completely alone, so take c out of it by subtracting c

-3x = -3 -2c

x = 1 +2/3c

so you would plug that in to solve for C

So you know what x is (or the substitute for it right now)

-3(1 + 2/3c) + 2c = -3

multiply or add

-3 - 2c + 2c = -3

c is 0 when you combine

-3x + 0 = -3

-3x = -3

x = 1

I have a triangle with side lengths of 2 cm, 3 cm, and 4 cm. If I have a second triangle that is similar that has a shortest side length of 4 cm, what is the longest side length?

Answers

so 2,3,4
another one is
4,x,y
the shortest is 2 and 4
4/2=2

2 time 2=4

the other triangle sides area obviously twice as large

2 times 2=4
2 times 3=6
2 times 4=8

the longest sides is 8 cm

Wendy is arranging books on the bookshelves in the school library. The total number of books she arranges is given by the equation b = 12r, where b is the total number of books and r is the number of rows. Each row contains the same number of books.If Wendy arranged 16 rows, she arranged a total of
books.

Answers

Given:
b = 12r
where:
b = represents the total number of books
12 = number of books per row
r = number of rows

If Wendy arranged 16 rows, she arranged a total of ___ books.

b = 12r
b = 12(16)
b = 192 total number of books arranged.

you would do 16x12 which is 192
