A typical golf ball having a diameter of approximately 1.5 inches has a volume of 1.8 cubic inches.

Volume refers to the amount of space occupied by a three-dimensional object.

From the problem, the golf ball resembles the Spaceship Earth geosphere at Epcot in Disney World in Orlando, Florida which is a sphere.

If a typical golf ball has a diameter of approximately 1.5 inches, and radius is half of the diameter, then the radius of the golf ball is approximately 0.75 inches.

The volume of the golf ball can be calculated using the formula for the volume of a sphere given by:

V = 4/3 π r^3

V = 4/3 π (0.75 inches)^3

V = 4/3 π (0.421875 cubic inches)

V = 1.767145868 cubic inches

Rounding off to the nearest tenth,

V = 1.8 cubic inches

The perimeter of right isosceles ΔABC with midsegment DE is 16 + 8√2.

If right isosceles ΔABC has hypotenuse length h, then the two other sides are congruent.

side a = side b

Using Pythagorean theorem, c^2 = a^2 + b^2

h^2 = a^2 + b^2      a = b

h^2 = 2a^2

a = h/√2

If DE is a midsegment not parallel to the hypotenuse, then it is a segment that connects the midpoints of one side of a triangle and the hypotenuse. See photo for reference.

ΔABC and ΔADE are similar triangles.

a : b : h = a/2 : 4 : h/2

If a/2 = a/2, then b/2 = 4.

b/2 = 4

b = 8

If a = b, then a = 8.

If a = h/√2, then

8 = h/√2

h = 8√2

Solving for the perimeter,

P = a + b + h

P = 8 + 8 + 8√2

P = 16 + 8√2

P = 27.3137085

Using a function to express the number of pieces of the two lengths, Evie should have 3 pieces of ribbon of length 12.5 cm and 5 pieces of ribbon of length 8.5 cm.

In mathematics, a function is the representation of the relationship of a set of input(X) and its corresponding output(Y).

If Evie has a price of ribbon that is 80cm long that she wants to cut into lengths of exactly 8.5cm or 12.5cm and that no ribbon left over, then the function for this statement is:

12.5x + 8.5y = 80     ⇒     y = (80 - 12.5x)/8.5

where x is the number of pieces of length 12.5 cm and y is the number of pieces of length 8.5 cm, and x and y must be whole numbers(pieces of ribbon)

Listing down the possible integers for the value of x and solving for the corresponding y value.

x = 1 , y = 135/17

x = 2 , y = 110/17

x = 3 ,  y = 5

x = 4 , y = 60/17

x = 5 , y = 35/17

x = 6 , y = 10/17

Since when x = 3, y = 5 is the only ordered pair that is both integers, then it is the answer.

The area of the trapezoid is 169.6 cm² for the dimensions as 8 cm, 5.7 cm and 15.5 cm.

We are given that:

The dimensions of the trapezoid are:

Height = 8 cm

Shorter side = 5.7 cm

longer side = 15.5 cm

Area of the trapezoid will be:

A = (a + b) / 2 × h

Substituting the values in the formula, we get that:

A = (5.7 + 15.5) / 2 × 8 cm²

A = 21.2 × 8 cm²

A = 169.6 cm²

Therefore, we get that, the area of the trapezoid is 169.6 cm² for the dimensions as 8 cm, 5.7 cm and 15.5 cm.

The simplified expression for (10-22 / 8-17) is 4/3 .

The given expression is,

( 10-22 / 8-17 )

First we need to solve the numerator which is (10-22) and on simplifying the numerator we can write,

Numerator = ( 10 - 22 ) = -12                         equation 1

Similarly, now we can proceed to solve the denominator which is (8 - 17) and on simplifying the denominator we write,

Denominator  = (8 - 17) = -9                       equation 2

Now we can substitute the value of numerator and the denominator from equation 1 and equation 2 in the given expression ( 10-22 / 8-17 ) as,

(Numerator / Denominator) = (10-22 / 8-17) = ((-12)/(-9)) = 4/3

The simplified expression for (16-12 / 15-11) is 4/3 .

The volume of sphere and hemisphere is 7×10⁵ inches and 3.5×10⁵ inches respectively.

We are given the area of circle. From this given information, we will be calculating radius of the circle, which will be further required to calculate volume of sphere and hemisphere.

Area of circle = πr²

Keep the value in formula -

55π = πr²

Cancelling  π and taking square root to find the value of radius

r = √55

r = 7.4 inches

Now, volume of sphere is calculated by the formula -

Volume of sphere = 4/3 πr³

Volume of sphere = 4/3 π (55)³

Volume of sphere = 6.97×10⁵ inches

Now, volume of hemisphere is calculated by the formula -

Volume of hemisphere = 2/3 πr³

Volume of hemisphere = 2/3 π (55)³

Volume of hemisphere = 3.48×10⁵ inches

On rounding off, we get volume of sphere and hemisphere as 7×10⁵ inches and 3.5×10⁵ inches

Hence, the volume of sphere and hemisphere is 7×10⁵ inches and 3.5×10⁵ inches respectively.

The missing 2nd term of the given arithmetic sequence 25, _, 53,...(a₂ = 39).

The difference between the two different numerical orders is a fixed number in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.

We'd come along through a few specific words in AP that were labeled as:

The AP can also be understood in terms of common differences, as shown below.

Now, for the given AP;   25, _, 53....

Let the initial term be 'a₁' = 25

Let the second term be 'a₂' = ?

Let the third term be 'a₃' = 53.

The AP must have the same common difference. So,

d =  a₂ - a₁ or d = a₃ - a₂

Equating the common difference to find the 2nd missing term.

a₃ - a₂ = a₂ - a₁

Substitute the given values;

53 - a₂ = a₂ - 25

Bring the variable part on one side.

Question 14

To find the function in terms of "x+2", simply replace "x" in the original equation with "x+2":

[tex]f(x+2)=-3(x+2)+4[/tex]

Now simplify by distributing the 3:

[tex]f(x+2)=-3x-6+4[/tex]

Finish by adding the constants:

For this question, it looks like you are given a set of coordinate pairs in the function. You are asked to find "f(4)". Essentially, you are being asked to find the value of y given 4 as the value of x.

The given coordinate pair (4,0) has 4 as the x value, so the y value when x=4 is 0!

Answer:

1.15 is 115%

Step-by-step explanation:

7/8 is 0.875 so it makes it 87.5%

The percentage form of the given number is:

1.15 as a percent is 115%

7/8 as a percent is 187.5%

To convert a decimal to a percent,

we need to multiply it by 100.

So for 1.15,

Multiply it by 100 to get 115%.

To convert a mixed number to a percent,

We have to convert it to an improper fraction first.

To do that, we multiply the denominator by the whole number and add the numerator.

Then we put that answer over the original denominator.

For 7/8, the improper fraction would be,

(8 x 1) + 7 = 15/8.

To convert this to a percentage,

We need to divide the numerator by the denominator and multiply by 100.

So 15/8 as a decimal is 1.875, and when we multiply that by 100 we get 187.5%.

The area of the quadrilateral ABCD is 26 square units

The quadrilateral ABCD is a trapezoid, and it  has the following parameters:

The lengths of these sides can be calculated using

d = √[(x2 - x1)^2 +(y2 - y1)^2]

So, we have

BC = √[(0 - 4)^2 +(3 + 1)^2] = 4√2

AD = √[(-5 - 4)^2 +(4 + 5)^2] = 9√2

CE = √[(2 - 4)^2 +(-3 + 1)^2] = 2√2

The area of the quadrilateral ABCD is then calculated as

Area = 0.5 * (BC + AD) * CE

This gives

Area = 0.5 * (4√2 + 9√2) * 2√2

Evaluate

Area = 26

Answer:

Step-by-step explanation:

The perfect square equation is f(x) = (x + 7/2)^2 - 9/4

The equation of the function is given as

f(x) = x^2 + 7x + 10

Rewrite the equation as

x^2 + 7x + 10 = 0

Subtract 10 from both sides of the equation

So, we have

x^2 + 7x = -10

-----------------------------------------------------------------------

Take the coefficient of x

k = 7

Divide by 2

k/2 = 7/2

Square both sides

(k/2) = 49/4

-----------------------------------------------------------------------

Add 49/4 to both sides of the equation

So, we have

x^2 + 7x + 49/4 = -10 + 49/4

Express as a perfect square

So, we have

(x + 7/2)^2 = -10 + 49/4

Evaluate the sum

So, we have

(x + 7/2)^2 = 9/4

This gives

(x + 7/2)^2 - 9/4 = 0

So, we have

f(x) = (x + 7/2)^2 - 9/4

Hence, the perfect square equation is f(x) = (x + 7/2)^2 - 9/4
