1)a bike costs $200 but is reduced by 35% in a sale. How much is the bike reduced by?What does it cost in the sale?

The amount of discount $70

New price $130

Step-by-step explanation:

To find how much 35% of 200 is, we multiply 200 with 35 then divide it with 100

200 × 35 ÷ 100 = 70 the bike's price is reduced by 70$ and the new price

20ü - 70 = 170$

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
