Of the pizzas recently sold at Pizza Pies, 6 had pepperoni and 26 did not. Considering this data, how many of the next 16 pizzas sold would you expect to have pepperoni?

Answer:

42.875

Step-by-step explanation:

First you find the x-intercepts and the vertex of the equation.

(-5, 0), (-2, 0), (-3/2, 49/4)

You use those coordinates to find the sides of the triangle and then you use the lengths to find the semiperimeter.

Lastly, you use Heron's formula to compute the area.

The area of the triangle is required.

The area of the triangle is [tex]42.875\ \text{units}^2[/tex]

[tex]y=-x^2-3x+10[/tex]

The x intercepts are

[tex]-x^2-3x+10=0\\\Rightarrow x=\dfrac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\left(-1\right)\times 10}}{2\left(-1\right)}\\\Rightarrow x=-5,2[/tex]

The x intercepts are

[tex](-5,0),(2,0)[/tex]

Distance between them is

[tex]2-(-5)=7\ \text{units}[/tex]

Vertex of a parabola is given by

[tex]x=-\dfrac{b}{2a}\\ =-\dfrac{-3}{2\times -1}\\ =-1.5[/tex]

[tex]y=-(-1.5)^2-3(-1.5)+10=12.25[/tex]

So,

Base = b = 7 units

Height = h = 12.25 units

Area is

[tex]A=\dfrac{1}{2}bh\\\Rightarrow A=\dfrac{1}{2}\times 7\times 12.25\\\Rightarrow A=42.875\ \text{units}^2[/tex]

Answer:

x=30

(Option 2)

Step-by-step explanation:

Well if the <1+<2=180 then you can put the equation as 4x+10+x+20=180. We can simplify that to be 5x+30=180. Minus 30 from both sides: 5x=150; x=30

Answer:

0.48

Step-by-step explanation:

Step-by-step explanation:

-3(x - 4) + x(2x + 3)

= (-3x + 12) + (2x² + 3x)

= 2x² + 12

= 2(x² + 6).

Answer:

[tex] - 3(x - 4) + x (2x + 3) \\ = - 3x + 12 + 2 {x}^{2} + 3x \\ = 2 {x}^{2} + 12 \\ = 2( {x}^{2} + 6)[/tex]

2(x^2+6) is the right answer.

Answer:

133.33

Step-by-step explanation:

In 133.33 years, the principal amount of $500 at the rate of 1.5% per year will triple.

Simple interest is an interest which is only based on principal amount, it does not imply on yearly interest.

Given that,

The principal amount put in the bank p= $500

The rate of simple interest r= 1.5 %

Amount will be triple, implies that, Interest would be two times of principal.

Interest = 2 x 500 = 1000

To find the time t, when amount gets triple, use simple interest formula

Interest = (p x r x t)/100

1000 = (500 x 1.5 x t)/100

200/1.5 = t

133.33 = t

The required time in which the money will triple is 133.33 years.

Answer: Green route = 5.8 miles

Blue route = 5.4 miles.

Step-by-step explanation:

Let the miles travelled for Green route be x

Let the miles travelled for Blue route be y

We can form an equation from the question given which will be:

8x + 9y = 95 ........ i

12x + 6y = 102 ......... ii

Multiply equation i by 12

Multiply equation ii by 8

96x + 108y = 1140 ....... iii

96x + 48y = 816 ....... iv

Subtract iv from iii

60y = 324

y = 324/60 = 5.4

Blue route is 5.4 miles.

Since 8x + 9y = 95

= 8x + 9(5.4) = 95

8x + 48.6 = 95

8x = 95 - 48.6

8x = 46.4

x = 46.4/8 = 5.8

Green route = 5.8 miles

Answer:

The numbers that meet these conditions are -3, -2 and -1.

This means that the wording of the question is somewhat ambiguous:

The lowest of the three numbers is -3.

The smallest however is -1.

You may need clarification on which of those is being asked for.

Step-by-step explanation:

Let's call those numbers a, b and c, with a the smallest and c the largest. We're told two key things here:

1) The sum of the smaller two integers is two more than seven times the largest integer.  In other words a + b = 7c + 2

2) We're looking for three consecutive integers, which means that we can define them with a single variable.  If the smallest one is a, then the others are a + 1 and a + 2.

We can take those and put them together, giving us the equation:

a + (a + 1) =  7(a + 2) + 2

Which we can then solve for a:

a + (a + 1) =  7(a + 2) + 2

2a + 1 = 7a + 14 + 2

2a - 7a = 14 + 2 - 1

-5a = 15

a = -3

Since a is -3 and also the smallest, we can then say that the numbers are -3, -2 and -1.

Answer:

x=8, y=25. As a point it's (8,25)

Step-by-step explanation:

here is the system:

y=x+17

y=3x+1

notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)

so it'll be:

3x+1=x+17

subtract 1 from both sides

3x=x+16

subtract x from both sides

2x=16

divide by 2

x=8

now, substitute 8 as x into one of the equations and solve for y

let's take the first one for example

y=8+17

y=25

so the answer is x=8, y=25. As a point it's (8,25)
