Cendrick D'Amitrano works Friday and Saturday delivering pizza. He delivers 8 pizzas on Friday. How many pizzas must he deliver on Saturday to average (mean) 11 pizzas per day?

Two parallel lines have same slopes so we need to find the slope of the line which passes through the given points.

Suppose : A = ( - 2 , 7 ) & B = ( 4 , 4 )

Slope = y ( B ) - y ( A ) / x ( B ) - x ( A )

Slope = 4 - 7 / 4 - ( - 2 )

Slope = - 3 / 4 + 2

Slope = - 3 / 6

Slope = - 1 / 2

------------------------------------------------------------

As you know The coefficient of x is the slope of the line in slope-intercept form.

Thus we have to find the option which x has - 1 / 2 as the coefficient .

Look we have that in D so the correct answer is D .

Answer:

[tex]v=400,000 \times (2)^d[/tex]

Step-by-step explanation:

Given that,

The value of a house is 400,000 in 2015 and it doubles every decade.

Let v be the value of the house.

We need to find an equation for v in terms of d (the number of decades since 2015).

It shows that the function is exponential. So,

[tex]v=ab^d[/tex]

Where

a = Initial Value = 400000

b = rate = 2

d = number of decades

v = the current value of the home

So,

[tex]v=400,000 \times (2)^d[/tex]

Step-by-step explanation:

Answer:

7x^2−2xy−7y

Step-by-step explanation:

First Simplify

(−8x)(y)+3x2−5y+4x2−2y+6xy

=−8xy+3x2+−5y+4x2+−2y+6xy

Then Combine Like Terms:

=−8xy+3x2+−5y+4x2+−2y+6xy

=(3x2+4x2)+(−8xy+6xy)+(−5y+−2y)

=7x2+−2xy+−7y

Answer:

AD = 19

Step-by-step explanation:

Here, we want to find the length of AD

To do this, we will use the illustration drawn below in the attachment

Since B is the midpoint of AC, and BC = 8; then AB will also be 8

Mathematically;

AD = AB + BD

AD = 8 + 11

AD = 19

Step-by-step explanation:

Let a be the total score of Div. A

Let b be the total score of Div. B

given,

[tex] \frac{a}{15} - \frac{b}{20} = 2[/tex]

as equation 1.

and

[tex]b - a = 160 \\ - a + b = 160[/tex]

as equation 2.

Now multiply equation 2 by 1/20 to eliminate b to solve for a.

[tex] ( - a)( \frac{1}{20} ) + (b)( \frac{1}{20} ) = ( \frac{1}{20} )(160) \\ - \frac{a}{20} + \frac{b}{20} = 8[/tex]

take this new equation as equation 3.

now we will use equation 1 + equation 3 to eliminate b to solve for a.

[tex] ( \frac{a}{15} + ( - \frac{a}{20} )) + ( - \frac{b}{20} + \frac{b}{20} ) = 2 + 8 \\ \frac{a}{60} = 10 \\ a = 60 \times 10 \\ = 600[/tex]

Div.A total score = 600

Average Score = Total Score / Number of students.

[tex] \frac{600}{15} \\ = 40[/tex]

Answer:

FV= $3,352.98

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $5,400

Number of periods (n)= 5 years

Interest rate (i)= 10%

To calculate the future value (FV), we need to use the following formula:

FV= PV / (1 + i)^n

FV= 5,400 / (1.1^5)

FV= $3,352.98

Answer:

a + 9

Step-by-step explanation:

Given that :

Melissa's current age = a

Melissa's age in 9 years will be will be expressed as :

Melissa's current age + number of years from present time

Thus ;

Expression to represent Melissa's age in 9 will be :

a + 9

Thus ;

Melissa's in 9 years = a + 9

Step-by-step explanation:

Answer:

4. (2,1) 5. (-2,1) 6. (8, 80)

Step-by-step explanation:

2x + 4y - 2x + 2y = 8 - 2

6y = 6

y = 1

2x + 4 = 8

2x = 4

x = 2

(2,1)

3x + 4y + 6x - 4y = -2 - 14

8x = -16

x = -2

-6 + 4y = -2

4y = 4

y = 1

(-2,1)

multiply first equation by 4

4y = 40x

4y + 40x + 6y = 40x + 800

10y = 800

y = 80

80 = 10x

x = 8

(8, 80)

The radius of the inflated beach ball is equal to 58 inches.

Surface Area of a Sphere. A = 4 π r². The volume of a Sphere. V = (4 ⁄ 3) π r³. Where r is the radius of the circle.

Given: The volume of the sphere is 14,310 inches³

we know the volume of the sphere is  4/3 πr³

Thus equating we get

4/3 × 3.14×r³=14310

r³=3417.99

r³=3418

r=58.463 or 58 (approx)
