Answer:

number of pennies = 54

Step-by-step explanation:

(4,60) ; (6, 65)

Find the slope

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

          =\frac{65-60}{6-4}\\\\=\frac{5}{2}

m = 5/2 and (4,60)

Equation of the line: y - y1 = m (x -x1)

y - 60 = \frac{5}{2}(x -4)\\\\y - 60 = \frac{5}{2}x-\frac{5}{2}*4\\\\y- 60 = \frac{5}{2}x-10\\\\y =\frac{5}{2}x-10+60\\\\y=\frac{5}{2}x + 50

x-----> determine the number of pennies and y determines the mass of pennies.

Here mass (y -value) is given as 185. We have find the corresponding x-value. So plugin  y  = 185 in the above equation,

185 = \frac{5}{2}x+50\\\\185-50=\frac{5}{2}x\\\\135=\frac{5}{2}x\\\\135*\frac{2}{5}=x\\\\27*2=x

x = 54

slega [8]

Answer:

3 foil, 6 latex

Step-by-step explanation:

First, you can put all of these words words into equations. We know there are 162 ballons (18 players)(9 bouquets). So we can put it in the equation

x + y = 162

Since each foil balloon costs $1.92 and each Latex balloon costs $.19 and they all cost $124.20. We can put it in an equation:

.19x + 1.92y = 124.20

You then get the systems of equations:

x + y = 162

.19x + 1.92y = 124.20

solving for the equation, you get x = 54 and y = 108. BUT, you have to be careful. The problem said "How many of each type of balloon did each <em>bouquet</em>​ include?" So we need to divide both by 18 for the player because each player recieved on bouquet.

How does doubling the lengths of the sides of a rectangle to form a similar rectangle affect the area
MrRissso [65]

Doubling the lengths of the sides of a rectangle quadruple the area

<h3>How to determine the effect?</h3>

Let the dimension of the rectangle be L and W.

So, the area is

A = LW

When the lengths are doubled, we have:

A2 = 2L * 2W

This gives

A2 = 4LW

This means that the initial area is multiplied by 4

Hence, doubling the lengths of the sides of a rectangle quadruple the area
