In a survey of 3,300 people who owned a certain type of car, 2,145 said they would buy that type of car again. What percent of

Alexxandr [17]

Answer:

65%

Step-by-step explanation:

In general to find %, divide the subset by the total amount and multiply by 100:

2145 / 3300 * 100 = 65%

Graph the image of this figure after a dilation with a scale factor of 12 centered at the point (2, 2) . Use the polygon tool to

Alla [95]

Answer:

Labelled the given figure triangle as A, B and C.

In triangle ABC;

The coordinates of ABC are:

A = (0, 4)

B = (-2, 10) and

C = (-6, 8)

To find the image of this figure after a dilation with a scale factor of $\frac{1}{2}$ centered at the point O=(2, 2).

The rule of dilation with scale factor $\frac{1}{2}$ centered at the point (2, 2) is given by;

$(x, y) \rightarrow (\frac{1}{2}(x-2) +2 , \frac{1}{2}(y-2) +2)$

or

$(x, y) \rightarrow (\frac{1}{2}x+1 , \frac{1}{2}y+1)$

The coordinate of the image of the figure after dilation are;

$A(0, 4) \rightarrow A'(\frac{1}{2}(0)+1 , \frac{1}{2}(4)+1)$ = A'(1, 3)

$B(-2, 10) \rightarrow B'(\frac{1}{2}(-2)+1 , \frac{1}{2}(10)+1)$ = B'(0, 6)

$C(-6, 8) \rightarrow C'(\frac{1}{2}(-6)+1 , \frac{1}{2}(8)+1)$ = C'(-2, 5)

You can see the graph as shown below in the attachment:

mridul jogs around a rectangular park of 100m by 80m at the rate of 9km per hour. how much time will he take in jogging 6 rounds

anyanavicka [17]

Answer:

14minutes

Step-by-step explanation:

first you need to find the distance which you must find the perimeter P=100+80+100+80

=360 so you multiple it by 6 to get

=2160meters

so you need to convert the meters to kilometers

which is 1000m =1km

what about 2160m you cross multiply

to get 2.16km.

so the distance represent D=2.16 km

and speed represent S=9km

now you need to find time represented by T

T=D/S

T=2.16km/9km/h

so the km cancels each other

you get 0.24h for this isn't the solution

you know that 1 hour= 60 minutes

 what about 0.24h you cross multiply

to get 14.4 so you round it off to get 14 minutes
