Hello from MrBillDoesMath!

Answer:

b = 28 degrees

Discussion:

In general,

sin (90 - @) = cos(@)

Set 90 [email protected] = 62  => @ = 28 so

sin (90-28) = sin(62) = cos(28)    => b = 28

Thank you,

MrB

3=6

In this case, the pattern is the number, in this case, 3, multiplied by the number below it.

See?
8\times7=56\\7\times6=42\\6\times5=30\\5\times4=20\\3\times2=6

An ice cream shop owner wants to find out what new flavor of ice cream he should sell in his shop. Which method would be the BES
nordsb [41]
D would be the most logical answer that I see. A does not help with what he is trying to accomplish. B Is not the best option because you don't wanna go to other places and see what different flavors they have cause you wanna be different you wanna create competition. C, your asking a couple of people that come into the shop and that number would vary. I just think D is the most logical answer because at least your asking a handful of people.    <span />

liam is reading a 254-page book for school. He can read 40 pages in one hour. The equation for the number of pages he has left t
Serggg [28]
Actually, it is
pages left=total pages-pages read
pages read=(number of pages per hour) times (number of hours)
numbe rof pages per hour=40
x=number of hours
254=total pages
so
y=254-40x, not 4x


what is the question
if it is how many hours to read the book then
0=pages left
0=254-40x
add 40x to both sides
40x=254
divide by 40
x=6.35
6.35 days or aprox 7 days


equation is y=254-40x where y=pages left and x=number of hours read
