At a store 20 feet of fencing cost $36 at the rate how much will 15 feet of fencing cost​
maria [59]

Answer:

15 feet of fencing costs $27

Step-by-step explanation:

We know 15/20 = 3/4 so...

36 x 3/4 = 27

Another way:

36 divided by 20 = 1.8

1.8 x 15 = 27

Solve for x. Enter the solutions from least to greatest. <br> (x+15)^2-10=0
Sergeu [11.5K]

Answer:

  • lesser x = -1.84
  • lesser x = -8.16

Step-by-step explanation:

Given the expression

\left(x+5\right)^2-10=0

Add 10 to both sides

\left(x+5\right)^2-10+10=0+10

Simplify

\left(x+5\right)^2=10

\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

solve

x+5=\sqrt{10}

Subtract 5 from both sides

x+5-5=\sqrt{10}-5

x=\sqrt{10}-5

x=-1.8

so

x+5=-\sqrt{10}

Subtract 5 from both sides

x+5-5=-\sqrt{10}-5

Simplify

x=-\sqrt{10}-5

\:x=-8.2

As -1.84 > -8.16

so

  • lesser x = -1.84
  • lesser x = -8.16

Maria graphs the following 3 equations: y = 34, y = 3x2, and y = 6x.
Yuliya22 [10]

Answer:

Maria is not correct.

The graph of y = 3x grows at an increasingly increasing rate, but the graph of y = 3x2 grows at a constantly increasing rate.

Therefore, the graph of y = 3x will eventually surpass the graph of y = 3x2.

Flauer [41]
To find the number of schedules knowing that she can only take one of each subject, you will multiply ALL the possible numbers of options for each.

2 x 3 x 3 x 4 =72

There are 72 different possible class schedules.
