Noralie has a home-based business putting on children’s parties. She charges $45 to design the party and then $5.50 per child. W

rite a function rule that relates the total cost of the party to the number of children n.
f(n) = 5.5 – 55n

f(n) = 5.5n – 55

f(n) = 5.5 + 45n

f(n) = 45 + 5.5n

Answer:

The answer would be C because n is the number of children and it costs $5.50 per child plus an extra design fee of $45

Step-by-step explanation:

Design = $45

rate per child = $5.50

number of children, x

total cost, f(x) = $5.5x + $45

What is the length of segment AB? (1 point) Coordinate grid shown from negative 8 to positive 8 on both x axis and y axis at int
Marina CMI [18]

Answer:

<h2>The distance between points A and B is 8.5 units, approximately.</h2>

Step-by-step explanation:

In the image attached you can observe a representation of the problem.

We have to find the distance between points A and B, which have coordinates (6,0) and (0,6), respectively.

The definition of distance between to given points is

d=\sqrt{(y_{2} -y_{1} )^{2} +(x_{2} -x_{1})^{2} }

Using points A and B, the distance between is

d_{AB}=\sqrt{(6-0)^{2} +(0-6)^{2} }  =\sqrt{36+36}=\sqrt{72} \\ d_{AB} \approx 8.5

Therefore, the distance between points A and B is 8.5 units, approximately.

Solve this inequality j/4-8&lt;4
liubo4ka [24]
First, you need to have j on it own. Since j is over 4-8, you times both sides of the inequality so the /4-8 is canceled. 

Your new inequality equation is j<4(4-8). Solve the bracket and then times the answer by 4.

~ j<4(-4)

~ j<-16

Cone W has a radius of 6 cm and a height of 5 cm. Square pyramid X has the same base area and height as cone W.
k0ka [10]

Answer:

Manuel's argument is correct. Paul used the incirrect base area to find the volume of square pyramid X

Step-by-step explanation:

step 1

Find the volume of the cone W

we know that

The volume of the cone if given by the formula

V=\frac{1}{3}\pi r^{2} h

we have

r=6\ cm\\h=5\ cm

substitute the given values

V=\frac{1}{3}\pi (6)^{2} (5)

V=60\pi\ cm^3

assume

\pi=3.14

substitute

V=60(3.14)=188.4\ cm^3

step 2

Find the volume of the square pyramid

we know that

The volume of the pyramid is given by the formula

V=\frac{1}{3}Bh

where

B is the area of the base

h is the height of pyramid

In this problem we have that

B=\pi r^2 ----> is the same that the area of the base of cone

so

B=3.14(6^2)=113.04\ cm^2

h=5\ cm ----> is the same that the height of the cone

so

substitute

V=\frac{1}{3}(113.04)(5)=188.4\ cm^3

therefore

Manuel's argument is correct. Paul used the incirrect base area to find the volume of square pyramid X
