Answer:

k = 40

Step-by-step explanation:

Given

The attached graph

Required

Calculate the constant of proportionality.

Represent the required constant with k.

Such that:

k = \dfrac{y}{x}

Pick any two corresponding values of x and y

(x,y) = (1,40)

This means that:

x = 1\ and\ y = 40

k = \dfrac{y}{x} becomes

k = \frac{40}{1}

k = 40

Answer:

<h2>a. V = 420 cm³</h2><h2>b. V = 444 in³</h2><h2>c. V = 108 cm³</h2><h2>d. V = 324 m³</h2>

Step-by-step explanation:

We have the rectangular prisms.

The formula of a volume of a rectangular prism is:

V=lwh

l - length

w - width

h - height

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

Look at the picture.

a.

Two congruent rectangular prisms 14cm × 3cm × 5cm.

V=2(14\cdot3\cdot5)=420\ cm^3

b.

One rectangular prism 15in × 4in × 6in and next 7in × 4in × 3in:

V=15\cdot4\cdot6+7\cdot4\cdot3=360+84=444\ in^3

c.

One rectangular prism 10cm × 3cm × 2cm and next 4cm × 3cm × 4cm:

V=10\cdot3\cdot2+4\cdot3\cdot4=60+48=108\ cm^3

d.

One rectangular prism 10m × 3m × 6m and next 8m × 3m × 6m:

V=10\cdot3\cdot6+8\cdot3\cdot6=180+144=324\ m^3

Cheese pizzas cost $7 and pepperoni pizzas cost $9. You order a total of 40 pizzas and the bill is $310. How many of each pizza
Anon25 [30]

Answer: cheese pizzas = 25 , Pepperoni pizzas = 15

Step-by-step explanation:

Let x = Number of cheese pizzas, y =  Number of pepperoni pizzas.

As per given,

x+y=40\ \ \ (i)\\\\ 7x+9y=310\ \ \ (ii)

Multiply 7 on both sides of (i), we get

7x+7y=280\ \ \ (iii)

Eliminate (iii) from (ii), we get

2y= 30\\\\\Rightarrow\ y=15

Put value of y in (i) ,  x+15=40\Rightarrow\ x= 40-15= 25

Hence, cheese pizzas = 25 , Pepperoni pizzas = 15
