A scale drawing of a rectangular park had a scale of 1 cm = 100 m. What is the actual area of the park in meters squared?​

Answer:

35.28 m

Step-by-step explanation:

Formula for volume of pyramid:

[tex]V=b^2\frac{h}{3}[/tex]

Therefore since,

base - 4.2 m

height - 6 m

Then,

[tex]V=4.2^2\frac{6}{3}[/tex]

[tex]V=35.28m[/tex]

Answer:

678.39

Step-by-step explanation:

For this we should probably use the formula A = Pe^rt. The question says that the value grow "continuously" which is our hint that we should use A = Pe^rt rather than A = P(1 +r/n)^nt. Our P = 620 as it is our initial value. e is a constant approx = 2.718. r is our rate, so 0.3% = 0.003, and our t will be in seconds. We need to figure out how many seconds are in .5 minutes, so 30, and that means our t will = 30. Let's plug these in. 620e^(0.003 * 30) = A. This will give us our answer which when rounded to the hundredths = 678.39.

Hope this is helpful.

Divide the parallelogram into two triangles, assume that our e diagonal is the "base" for both new triangles. What's the height of that triangle? Use the sine function. It's (f/2) * sin (angle)! The area of the triangle is equal to our "base" e times height: e * (f/2) * sin (angle)

The base is 12 feet long, the height is 17 feet long.

Answer:

n = 84

Step-by-step explanation:

18 + 3 = 21, so that means the quotient of the number and 4 is 21.

21 * 4 = 84

CHECK:

84 / 4 = 21

21 - 3 = 18

Hey there!

33 - y = 6

33 - 1y = 6

-1y + 33 = 6

-y + 33 = 6

SUBTRACT 33 to BOTH SIDES

-y + 33 - 33 = 6 - 33

SIMPLIFY IT!
-y =6 - 33

-y = 6 - 33

-1y = -27

DIVIDE -1 to BOTH SIDES

-1y/-1 = -27/-1

SIMPLIFY IT!
y = -27/-1

y = 27

Therefore, your answer is: y = 27

Good luck on your assignment & enjoy your day!

Step-by-step explanation:

the perimeter (P) is the sum of the 3 sides of the triangle, then

P = 31 + 19.5 + 16.2 = 66.7 units

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 16.2 and h = 13 , then

A = [tex]\frac{1}{2}[/tex] × 16.2 × 13 = 8.1 × 13 = 105.3 units²

The difference in volumes between cube and cone is 5190.52 cubic units.

Suppose that:

The side length of the considered cube is L units.

Then, we get:

The volume of that cube = L³ cubic units.

The outer figure is a cube with an edge length of 20 centimeters.

The volume of that cube = L³ cubic units.

= 8000 cubic units.

The volume of that cone

[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]

The height is 20 cm and the radius will be

[tex]D = 20\sqrt{2} \\ = 28.2\\\\r = D/2\\ = 14.1[/tex]

volume of that cone

[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]

= [tex]V = \dfrac{1}{3} (3.14) (14.1)^3 (20) \: \rm unit^3[/tex]

= 59190.52  cubic units

Therefore, the difference in volumes bbetween cube and cone is 5190.52 cubic units.

Answer:

Dan is correct

Step-by-step explanation:

Mean = the sum of all data values divided by the total number of data values

Number of adults in Sample A:

= 70 + 90 + 135 + 140 + 65 = 500

Mean of Sample A:

= [ (1 × 70) + (2 × 90) + (3 × 135) + (4 × 140) + (5 × 65) ] ÷ 500

= 1540 ÷ 500

= 3.08

Number of adults in Sample B:

= 80 + 80 + 130 + 135 + 75 = 500

Mean of Sample A:

= [ (1 × 80) + (2 × 80) + (3 × 130) + (4 × 135) + (5 × 75) ] ÷ 500

= 1545 ÷ 500

= 3.09

Mean of the two samples:

= (3.08 + 3.09) ÷ 2

= 3.085 hours

= 3 hours (nearest hour)

The mean of Sample A is 3.08 hours and the mean of Sample B is 3.09 hours, so the mean of the entire sample is 3.085 hours.  If we round this to the nearest hour, then the mean is 3 hours.  Therefore, Dan is correct in concluding that the adults spend a mean of 3 hours each day doing leisure and sports activities.
