PLEASE HELp tHHIS IS dUE IN AN HOUR!!!!! ITS MY LAST QuESTION Tony and Tiffany colleg\ct semi-precious stones. At the Rockhound
DIA [1.3K]

Answer:

Tiffany purchase the better buy.

Step-by-step explanation:

given data

Tiffany paid  = $38

snowflake obsidian = 9 pounds

Tony paid = $19

same type of stone = 3 pounds

solution

Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each

so for Tiffany

= $38 ÷ 9

= $4.22 per pound

and for Tony  

=$19 ÷ 3

= $6.33 per pound

so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound

so here whole $2.11 more than Tiffany

so that with this Tiffany purchase the better buy.

Parallelogram PARL is similar to parallelogram WXYZ. If AP = 15, PL = 40, and WZ = 120, find the value of c .50 110 6 45
vova2212 [387]

Answer:

Option D. c = 45 will be the answer.

Step-by-step explanation:

In the figure attached there are two similar parallelograms PARL and WXYZ.

In which AP = 15, PL = 40, WZ = 120 and WX = c

By the property of similarity, corresponding sides of the given parallelograms will be in the same ratio.

\frac{PL}{WZ}=\frac{PA}{WX}

\frac{40}{120}=\frac{15}{c}

c = \frac{15\times 120}{40} [By cross multiplication]

c = 45

Therefore, Option D. c = 45 will be the answer.

CAN SOMEONE PLEASE
pishuonlain [190]

Answer: The graph is shown below

The solution to the system is (x,y) = (2,3)

=============================================================

Explanation:

To graph y = \frac{5}{2}x-2, we need two points. Generating any (x,y) point involves picking a random x value to find its paired y value. For instance, if you plugged in x = 0, you should get to y = -2 which is the y intercept. Then trying something like x = 2 will lead to y = 3. This line goes through (0,-2) and (2,3). This line is shown in red below.

The blue line is horizontal and goes through 3 on the y axis. Every point on this horizontal line has the same y coordinate of 3. The x value doesn't matter, so it's not part of the equation y = 3.

The intersection of the red and blue line is the solution to the system. That intersection occurs at (x,y) = (2,3). This means x = 2 and y = 3 pair up together to make both original equations true.

Since this system has at least one solution, we consider it a consistent system.

<u>Algebra I</u>

  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -2x + 4

2x + y = 4

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                  2x + (-2x + 4) = 4
  2. Combine like terms:                                                                                         4 = 4

Here we see that 4 does indeed equal 4.

∴ the systems of equations has an infinite amount of solutions.

the angle of elevation of the top of a building from a point 80 ft away from the building on level ground is 70° determine the b
MA_775_DIABLO [31]
Draw a triangle with shortest side on the ground (horiz.).  The length of this side is 80 feet.  Two angles touch the ground:  a right angle, and the 70 degree angle.
 
Then the height of the building is the 2nd shortest side.

The tangent function is the appropriate one to use here:
                       opp          h
tan 70 deg = -------- = ----------
                        adj        80 ft
                                                                h
Since tan 70 deg  = 2.75,          2.75 = -------
                                                              80 ft

so h = building height = (80 ft)(2.75) = 219.8 ft
