Answer:

  $66

Step-by-step explanation:

It can be convenient to assign a different variable to the amount of money each spent. We can call the amounts spent by Seedevi, Georgia, and Amy "s", "g", and "a", respectively.

The problem statement tells us ...

  s = (1/2)g

  s = a +6

  s + g + a = 258

__

The problem statement asks for the amount Seedevi spent, so we need to find the value of s. It is convenient to write the other variables in terms of s:

  g = 2s

  a = s -6

Then the sum is ...

  s + (2s) +(s -6) = 258

  4s = 264 . . . . . . . . . . . add 6, simplify

  s = 66 . . . . . . . . . . . . . .divide by 4

Seedevi spent $66.

miv72 [106K]

Answer:

The probability that a house has a backyard given that has a garage is 76.60%.

Step-by-step explanation:

Given that in New England 47% of the houses have a garage and 36% of the houses have a garage and a backyard, to determine what is the probability that a house has a backyard given that has a garage the following crossed multiplication must be performed:

47 = 100

36 = X

(36 x 100) / 47 = X

3,600 / 47 = X

76.5957 = X

Therefore, the probability that a house has a backyard given that has a garage is 76.60%.

Can someone explain just 17-28??
Tatiana [17]

Answer:

you solve these by plugging the numbers into pythagorean theorem which is

a^2 + b^2 = c^2 (a squared plus b squared equal c squared)

C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)

so 17 would be 9.5^2 + 3.8^2 = c^2

So 90.25 + 14.44 = c^2

104.69=c^2

Then to solve for c take the square root of each side and get

10.23=c

To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it

I need to know the answer.
katrin [286]

Well, apologies if this is wrong but in my opinion, I think it's that The angles do not change. This is because the angles are alright staying in the same place. I don't understand much about angles but it makes the most sense to me.
