Find the missing value. 7/8 = x/28.8 Please help, I clearly have no brain cells left, and I have the brain capacity of a Carrot ;-;
============================================
Work Shown:
7/8 = x/28.8
7*28.8 = 8*x .... cross multiply
201.6 = 8x
8x = 201.6
x = 201.6/8 ... divide both sides by 8
x = 25.2
The missing value of x is 25.2.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let the missing value is x.
Given:
7/8 = x/28.8
7(28.8) = 8x
Cross multiply;
201.6 = 8x
8x = 201.6
x = 201.6/8
Divide both sides by 8;
x = 25.2
Hence, The missing value of x is 25.2.

Find the equation of line that passes through the points (2.0) and (4.6). Write the equation in slope-intercept form
Answer:
y = 3x - 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (4, 6)
m = [tex]\frac{6-0}{4-2}[/tex] = [tex]\frac{6}{2}[/tex] = 3, then
y = 3x + c ← is the partial equation
To find c, substitute either of the 2 points into the partial equation
Using (2, 0 ) , then
0 = 6 + c ⇒ c = 0 - 6 = - 6
y = 3x - 6 ← equation of line

The Smith family is trying to decide what theme park to visit on their vacation. Family Fun Land costs $12 per person and $40 for parking. Blue Jay Bay costs $22 per person and $12 for parking. Explain their different options depending on how many people go.
Answer: For groups with over 3 people, Family Fun Land is the best option. It's cheapest for groups of 1 or 2 to go to Blue Jay Bay.
Step-by-step explanation:
Family Fun Land | y = total $, x = # of people
y = 12x + 40
Blue Jay Bay
y = 22x + 12
2 People
y = 12(2) + 40
y = 64
y = 22(2) + 12
y = 56
3 People
y = 12(3) + 40
y = 76
y = 22(3) + 12
y = 78

treating prostate disease a large study used records from canada’s national health care system to compare the effectiveness of two ways to treat prostate disease. the two treatments are traditional surgery and a new method that does not require surgery. the records described many patients whose doctors had chosen each method. the study found that patients treated by the new method were sig- nificantly more likely to die within 8 years.38
The cost and the patient's condition are other factors. For instance, a doctor might decide against suggesting surgery if a patient has very bad health because of the potential for additional difficulties. Then, we won't be able to tell if a higher death rate is a result of the therapy or the participants' pre-existing health.
What distinguishes surgical treatment from medicinal treatment? What distinguishes surgical procedures from nonsurgical ones?What Kinds of Practices Are Not Surgical?Any condition that necessitates a localised treatment, such as surgery or one of the many vascular procedures or radiation methods, is referred to as a surgical disease. A more comprehensive, pharmacological strategy to treat a medical issue is required.
"Non-surgical" treatments are also referred to as "non-invasive" procedures in the cosmetic industry. These techniques don't need cutting the skin or inserting tools into the body, in contrast to "invasive" surgical therapies.

Step-by-step explanation:
A cylinder shaped container is used to hold watef . This cylinder has a height of 12 inches and a diameter of 7 inches . A spherical ball with a diameter of 6 inches is dropped into the container . Explain how the ball changes the volhme of the water the container can hold and calculate the amount of water the cylinder can hold after the ball is dropped into the cylinder . Let pi = 3.14
Answer:
423.9 inches³
Step-by-step explanation:
First we will calculate the volume of the cylinder using the formula
Vc = hπr²
Vc = 12π(3.5)² [radius is 1/2 diameter]
Vc = 147π
Next we calculate the volume of the sphere using 4/3*πr³
Vs = 4/3 πr³
Vs = 4/3π3³
Vs = 12π
Finally, we subtract the volume of the cylinder by the volume of the sphere to get the remaining volume in the cylinder that can be filled with water.
147π - 12π = 135π
Using the approximate 3.14, the answer is 423.9 inches³
Prove that:
(A cos x + B sin x)^2 - (B cos x + A sin x)^2 = (A^2 - B^2) (cos^2x - sin^2x)
Answer:
see explanation
Step-by-step explanation:
Consider the left side
(Acosx + Bsinx)² - (Bcosx + Asinx)² ← expand factors using FOIL
= A²cos²x + 2ABsinxcosx + B²sin²x - (B²cos²x + 2ABsinxcosx + A²sin²x)
= A²cos²x + 2ABsinxcosx + B²sin²x - B²cos²x - 2ABsinxcosx - A²sin²x
= A²cos²x - Bcos²x + B²sin²x - A²sin²x ← factor first/second and third/fourth terms
= cos²x(A² - B²) - sin²x(A² - B²) ← factor out (A² - B²) from each term
= (A² - B²)(cos²x - sin²x)
