Answer:

The average number of people per car is 2.91

Step-by-step explanation:

To find the average number of people per car, we divide the total number of people by the total number of cars.

We have that:

57 cars had 4 people

61 cars had 2 people

9 cars had 1 person,

5 cars had 5 people.

Number of people:

57*4 + 61*2 + 9*1 + 5*5 = 384

Number of cars:

57 + 61 + 9 + 5 = 132

Average:

384/132 = 2.91

The average number of people per car is 2.91

Here is the scale model of a fountain at a museum the scale is 1:30 how many boulders are in the real fountain
wlad13 [49]

Answer:

When we do a scale model of something (like a building, a house, or whatever) al the properties of the original thing must also be in the model.

So for example, you want to do a model of a house, and in the backyard of the house there are 4 trees, then in the model of the house you also need to put 4 trees in the backyard (indifferent of the scale of the model).

Then the number of boulders in the really fountain should be the same as the number of boulders in the scale model of the fountain.

Tanisha and Neal are simplifying the expression . They each began the same way. Tanisha’s Work Neal’s Work Which statements are
valentina_108 [34]

Answer:

The correct simplified answer is \frac{1}{8} \left (\frac{x}{ y}  \right )^{8} or  \frac{x^8}{81\cdot y^8}

Step-by-step explanation:

Here we have the expression as

\left (\frac{(x^4)(y^{-5})}{3(x^2)(y^{-3})}   \right )^{4}

Tanisha's work

\left (\frac{(x^4)(y^{-5})}{3(x^2)(y^{-3})}   \right )^{4} = \left (\frac{(x^2)(y^{-2})}{3}   \right )^{4}

Neal's work is

\left (\frac{(x^4)(y^{-5})}{3(x^2)(y^{-3})}   \right )^{4} = \left (\frac{(x^{16})(y^{-20})}{3^4(x^8)(y^{-12})}   \right )

The correct simplified answer is   \frac{x^8}{81\cdot y^8}.

which can also be expressed as

\frac{1}{8} \left (\frac{x}{ y}  \right )^{8}

Both form represent simplified forms of the original equation.

Which sequence of transformations produces R'S'T' from RST? On a coordinate plane, triangle R S T has points (0, 0), (negative 2
arsen [322]

Answer:

Step-by-step explanation:

Given is a triangle RST and another triangle R'S'T' tranformed from RST

Vertices of RST are (0, 0), (negative 2, 3), (negative 3, 1).

Vertices of R'S'T' are  (2, 0), (0, negative 3), (negative 1, negative 1).

Comparing the corresponding vertices we find that x coordinate increased by 2 while y coordinate got the different sign.

This indicates that there is both reflection and transformation horizontally to the right by 2 units

So first shifted right by 2 units so that vertices became

(2,0) (0,3) (-1,1)

Now reflected on the line y=0 i.e. x axis

New vertices are

(2,0) (0,-3) (-1,-1)

Mario has a business selling muffins. Let x be the price of a muffin. Then, the profit P for Mario’s business is given by p(x)=-
Rufina [12.5K]
To make a positive profit p(x)>0 we need to make:
-100 x^{2} +350x-150 \ \textgreater \  0

Now we solve this for x:
-2 x^{2} +7x-3 \ \textgreater \ 0

We have:
a = -2
b = 7
c = -3

We will use formula for quadratic equation:
x_{1} =  \frac{-b+ \sqrt{ b^{2}-4ac } }{2a}  \\  \\  x_{2} =  \frac{-b- \sqrt{ b^{2}-4ac } }{2a}  \\  \\  x_{1} =  \frac{-7+ \sqrt{ 49-24 } }{-4} = \frac{-7+5 }{-4} = \frac{-2 }{-4} = \frac{1}{2}  \\  \\  x_{2} =  \frac{-7- \sqrt{ 49-24 } }{-4}  = \frac{-7-5 }{-4} = \frac{-12 }{-4} = 3

We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
