Hello!

To find how many meters are in 66 feet, we divide by 3.3 as shown below.

66/3.3=20

Therefore, 66 ft is equal to 20 meters.

I hope this helps!

If 1m = 3.3ft, it means that to find how many meters there are in a foot we do:

m * ft = x

m = amount in meters

ft = equivalent amount in feet

x = result

Therefore, to find the amount of meters in a foot:

ft / m = x

ft = amount in feet

m = equivalent amount in meters

x = result

Now we apply the formula to our case:

66 / 3.3 = 20

Answer:

\boxed{\bf~66ft~=~20m}

Hope it helped,

quadrilateral ABCD is dilated by a scale factor of 2 centered around (2,2). Which statement is true about the dilation?
Setler [38]

Answer:

The vertices of the image will have the coordinates

A(-5, 1) → A'(2x-2, 2y-2) → A'(-12, 0)

B(-4, 3) → B'(2x-2, 2y-2) → B'(-10, 4)

C(1, 2) → C'(2x-2, 2y-2) → C'(0, 2)

D(-3, 0) → D'(2x-2, 2y-2) → D'(-8, -2)

Step-by-step explanation:

<em>Note: You missed to mention the vertices of a quadrilateral ABCD. So, I am assuming the following vertices. It would anyways clear your concept.</em>

<em />

Let us suppose

  • A(-5, 1)
  • B(-4, 3)
  • C(1, 2)
  • D(-3, 0)

We know that the rule of the dilation with the center of dilation at (2,2) by a scale factor of 2 is:

  • (x, y) → (2x-2, 2y-2)

Therefore, the vertices of the image will have the coordinates

A(-5, 1) → A'(2x-2, 2y-2) → A'(-12, 0)

B(-4, 3) → B'(2x-2, 2y-2) → B'(-10, 4)

C(1, 2) → C'(2x-2, 2y-2) → C'(0, 2)

D(-3, 0) → D'(2x-2, 2y-2) → D'(-8, -2)

The school want to purchase enough tarp material to cover their field during bad weather. They want to get exactly eleven percen
KonstantinChe [14]

Answer:

6660 yards^2

Step-by-step explanation:

Assumption: the field is 120 yards long and 50 yards wide.

First calculate the area of the field: 120*50 = 6000 yards^2

Then, calculate the 11% of that area:  6000 yards^2*11/100 = 660 yards^2

Finally, the area of the tarp material should be 6000 yards^2 + 660 yards^2 = 6660 yards^2

A recent national survey found that high school students watched an average (mean) of 6.8 movies per month with a population sta
Margaret [11]

Answer:

Step-by-step explanation:

Given that x = no of movies high school students watched is N(6.8, 1.8)

Sample size = 36 and hence std error = 1.8/6 = 0.3

H_0: x bar = 6.8\\H_a: x bar < 6.8\\

(two tailed test)

Mean difference = 6.2-6.8 = -0.6

Test statistic z = -0.6/0.3= -2

p value = 0.02275

Since p <0.05 we reject H0.

There is evidence to show that college students watch fewer movies a month than high school students
