An architect planned to construct two similar stone pyramid structures in a park. The

kondaur [170]

Answer:

1) Change the length of side AB to 2 feet

Step-by-step explanation:

Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.

To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:

$\frac{PR}{AC} = \frac{PQ}{AB}$

We will assume AB is unknown.

PR = 7.5 ft

AC = 2.5 ft

PQ = 6 ft

Plug in the values into the equation

$\frac{7.5}{2.5} = \frac{6}{AB}$

Cross multiply

$AB*7.5 = 6*2.5$

$AB*7.5 = 15$

Divide both sides by 7.5

$AB = 2$

The architect should change the length of AB to 2 ft

PLEASE HELP PLEASE

The x-coordinate in the solution of the system of equations y = -2/3x and 4x - 9y = -40 is -4

<h3>Solution:</h3>

Given that system of equations are:

$y = \frac{-2}{3}x$ ------- eqn 1

$4x - 9y=-40$ ------ eqn 2

We have to solve the above given system of equations and find the x - coordinate

Substitute eqn 1 in eqn 2 and solve for "x"

$4x - 9(\frac{-2}{3}x) = -40\\\\4x + \frac{18x}{3} = -40\\\\12x + 18x = -120\\\\30x = -120\\\\x = \frac{-120}{30} = -4$

x = -4

Thus the x-coordinate in the solution of the system of equations is -4

Answer:

9300

Step-by-step explanation:

To find the total surface are of 150 boxes, all we have to do is multiply the surface area of one box ( 62 which was calculated on this question brainly.com/question/23446865 ) by the total amount of boxes (150)

So your answer = 150 * 62 which equals 9300
