Answer 1
Answer:

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!
Answer 2
Answer:

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,

Three balls are packaged in a cylindrical container as shown below. The balls just touch the top, bottom, and sides of the cylinder. The diameter of each ball is 13 cm. a. What is the volume of the cylinder? Explain your method for finding the volume.
b. What is the total volume of the three balls? Explain your method for finding the total volume.
c. What percent of the volume of the container is occupied by the three balls? Explain how you would find the percent.

Answers

We know the following:
Cylinder volume: V₁ = π r² h
Ball (sphere) volume:V₂ = (4)/(3) π r³
where:
V - volume
r - radius of base of cylinder and diameter of ball
h - height of cylinder.

R = 13 cm ⇒ r = 13 ÷ 2 = 6.5
π = 3.14

a) Since balls touch all sides of cylinder (as shown in image), it can be concluded that height of cylinder is equal to sum of diameters of 3 balls and that radius of base of cylinder is equal to radius of ball:
h = 3 × r = 3 × 13 cm = 39 cm
r = 6.5 cm
So,
V₁ = π r² h
V₁ = 3.14 × (6.5 cm)² × 39 cm
V₁ = 5,173.9 cm³

b. The total volume of three balls is the sum of volumes of each ball:
Vₐ = 3 × V₂ 
Vₐ = 3 × (4)/(3) π r³
Vₐ = 3 × (4)/(3) 3.14 (6.5 cm)³
Vₐ = 3,449.3 cm³

c. Percentage of the volume of the container occupied by three balls ould be expressed as ratio of volume of three balls and volume of cylinder:
V = ( V_(1))/( V_(a) ) ×100 
V = (3,449.3)/(5,173.9) ×100
V = 0.6666 ×100
V = 66.66%
A. The volume of the cylinder can be computed because the statement "The balls just touch the top, bottom, and sides of the cylinder" gives a clue of the height and radius of the cylinder. The height is equal to 3 times the diameter of the balls, and its radius is the same as the balls' radius.

Vcylinder = πr^2h = π(13/2)^2 (3*13) = 5176.56 cm^3

B. The volume of the three balls is computed using the equation of V for spheres:

Vball = 3*4*π*r^2/3 = 3451.05 cm^3

C. The answer is the equal to the total volume of the balls divided by the volume of the cylinder

3451.05(100%)/5176.56 = 66.67%

Y varies directly as x , y= 25 when x=5. Determine y when x= 13

Answers

Answer:

y = 65 when x = 13

Step-by-step explanation:

Here we have a proportion problem.

Y varies directly as x means that y equals the product of x and a constant

Let’s say our constant is k

Thus;

y = kx

now, k = y/x

Using the initial values;

k = 25/5 = 5

Now we want to get y when x = 13

Recall; y = kx

Thus using the value of k earlier calculated;

y = 13 * 5

y = 65

Lyra and Donna are testing the two-way radios they built for their high school science project. Lyra goes to the top of a building that is 22 meters high with one of the radios and stands directly above the building’s entrance. Donna walks out of the entrance, perpendicular to the building, with the other radio. If Donna is more than 50 meters from the entrance, the connection between the radios breaks. What is the range of communication for the two radios to the nearest meter?

Answers

We use the Pythagorean Theorem: c^2=a^2+b^2. In this case :
c-nearest range between two radios
a=22 m ( height of a building)
b=50 m ( distance from an entrance)
c^2=22^2+50^2˝=484+2500=2984
Finally: c=sqrt(2984) (square root of 2984)=54.626 m
Answer: The range of communication for the two radios is 54.626 meters. 

a bottle rocket that was made in science class has a trajectory path that followed the quadratic equation y equals negative x squared + 4x + 6 what is the turning point of the Rockets

Answers

y= -x^(2)+4x+6

Turning points occur when the gradient of the function is zero.
(dy)/(dx) =-2x+4
Then equating to 0;
-2x+4=0
-2x=-4
x=2

From the fucntion, when x=2 ;
y=-(2)^(2)+4(2) +6
y=-8+8+6
y=6
Turning point;

$3,180

b.

$3,920

c.

$4,980

d.

$11,340

Answers

The total cost for Neil to get his degree is $4980 so option (C) will be correct.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Total tuition fees;

6 × 530 = $3180

Books cost = $1800

Total cost to get a degree = Total tuition fees + Books cost

Total cost to get a degree = 3180 + 1800 = $4980.

Hence "The total cost for Neil to get his degree is $4980".
