Mathematics
1 answer:
navik [9.2K]2 years ago
5 0

Answer:

y = -9x - 1

Step-by-step explanation:

Step 1:

y = 8, x = -1

By putting the above values in equation (i)

8 = -9 (-1) + b

8 = 9 + b

-1 = b

b = -1

y = -9x - 1

On the first day, Maria and Emily make flowers together for 1 hour and 25 minutes. In the time it takes Emily to make 2 paper fl
qwelly [4]
Okay, this is a proportion question. they make 45 flowers every 1 hour and 25 minutes, or 45/85(85 is equivalent to 1 hour and 25 minutes). and they made 100 flowers at the same rate as the first day. so you need to know how long it took them to make 100 flowers, if they make 45 every 85 minutes. so 45 (flowers) to 85 (minutes) = 100 (flowers) to x (minutes). or 45/85=100/x. so when you work that out, I came to 189 minutes, which is 3 hours and 9 minutes, so they stopped at 4:24. But you could round and get 4:25. Hope I didn't confuse you!

An artist is constructing a piece of art in the shape of rectangle. The artist wants to use string to tightly tie each vertex of
Liula [17]

Answer:

  65.8 ft

Step-by-step explanation:

The number of strings required to tie each vertex to the other three will be ...

  (4)(3)/2 = 6

Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.

  d² = 12² +7² = 144 +49 = 193

  d = √193 ≈ 13.892

Then the total length of all strings is ...

  L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet

The artist will need 65.8 feet of string.

How do you sole this question kelpie sold cameras on her web site. She bought the cameras for $65 each included a 60% markup to
postnew [5]
So 65 dollars was what she paid
each camera INCLUDED a 60% mark UP so
she sold each at a 60% markup

65 dollars=100% of origonal camers
she sold them for 100+60=160% of origonal price
65 dollars=100%
percent means parts out of 100 so
160%=160/100=1.6

find 160% of 65
'of' means multiply so
1.6 times 65=104

she sold each camera at $104
