First, find angle ECD using tan^-1(6/4), we get angle as 56.31

Now by proportionate, angle ECD and angle EBA are equal.

Hence you can use tan to find AB i.e, AB = 18/tan(56.31)= 12

Therefore, AB = 12

Melanie connected a brown garden hose, a green garden hose, and a black garden hose to make one long hose. The brown hose is 10.
natta225 [31]

Answer:

35.65 feet

Step-by-step explanation:

Melanie connected a brown garden hose , a green garden hose and a black garden hose to make one long hose

The brown hose is 10.75 feet

The green hose is 16.4 feet

The black hose is 8.5 feet

Therefore the farthest distance that the one hose can reach can be calculated as follows

= 10.75 + 16.4 + 8.5

= 35.65 feet

Hence the farthest distance that one hose can reach is 35.65 feet

Select all the expressions that are equivalent to -36x+54y−90.
CaHeK987 [17]

Answer:

b) -18(2x -3y + 5)

d) 18(-2x + 3y - 5)

e) -2(18x - 27y + 45)

Step-by-step explanation:

a) -9( 4x - 6y - 10) = -36x + 54y + 90 not equal

b) -18(2x - 3y + 5) = -36x + 54y - 90 equal

c) -6(6x + 9y - 15) = -36x - 54y + 90 not equal

d) 18(-2x + 3y - 5) = -36x + 54y - 90 equal

e) -2(18x - 27y + 45) = -36x + 54y - 90 equal

f) 2(-18x + 54y - 90) = -36x + 108y - 180 not equal

In order to find the y-intercept, replace x by 0.

So, for first option:
f(0) = 7(1) - 2 = 5

For second option:
f(0) = -3(1) - 5 = -8

For third option:
f(0) = 5(1)-1=4

For Fourth option:
f(0) = -5(1) + 10 = 5

For Fifth Option:
f(0) = 2(1) + 5 = 7

So, option 1 and 4 have the y-intercept (0,5)
