Answer:

If your definition of "Cover" is to fill it in, than there is no longer a hole.

If your definition of "Cover" is to simply "cover" the hole and not filling it, there is still a 12 feet hole.

Unless your perspective is that there is no hole simply because it was Covered.

a scale drawing of a building needs to be made using the scale 1 in = 190 ft. how tall will the builging in the scale drawing be

Artist 52 [7]

Answer:

$\boxed{\text{3 in}}$

Step-by-step explanation:

1 in = 190 ft

x in = 570 ft

We can use ratio and proportion to solve this problem.

$\begin{array}{cccl}\dfrac{1}{x} & = & \dfrac{190}{570} & \\\\570 & = & 190x & \text{Mutiplied by lowest common denominator (570x)}\\3 & = & x & \text{Divided each side by 3}\\\end{array}$

The building will be $\boxed{\textbf{3 in}}$ tall in the scale drawing.

Solve for the equation for all x values by completing the square x^2 - 27= 67

navik [9.2K]

Answer:

The solutions for the equation $x^2\:-\:27=\:67$ are $x=\sqrt{94},\:x=-\sqrt{94}$ .

Step-by-step explanation:

To find the solutions for the equation $x^2\:-\:27=\:67$ you must:

$\mathrm{Add\:}27\mathrm{\:to\:both\:sides}\\\\x^2-27+27=67+27$

$\mathrm{Simplify}\\\\x^2=94$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\x=\sqrt{94},\:x=-\sqrt{94}$

Jonathan is planning a party at the skating rink. The cost for each person attending is 3.50 for sate rental and $5.00 for food.

Zina [86]

He can only invite 35 people

the cost per person = $3.50 + $5.00 = $8.50

dividing $300 by $8.50 determines the amount he can invite

$\frac{300}{8.5}$ = 35.29411...

He can invite 35 people at a cost of $8.50 × 35 = $297.50
