Rsm question please help!

Step-by-step explanation:

we need to use both equations for the volumes.

the only variables in them are r1 and r2.

when we say both results (volumes) are equal, that means we can create an equation with one formula on one side and the other formula on the other side.

and then we can easily transform the equation into "r1 = ..." or "r2 = ..."

and yes, your teacher made a mistake by hinting to solve for r1 in a. and b. it is r1 in a. and r2 in b.

a.

the goal here is an equation in the form

"r1 = ..."

that means r1 is a function of r2.

36×pi×r1² = 1/2 × 4/3 × pi × r2³ = 4/6 × pi × r2³ =

= 2/3 × pi × r2³

36 × r1² = 2/3 × r2³

r1² = (2/3 / 36) × r2³ = (1/(3×18)) × r2³ = 1/54 × r2³

r1 = sqrt(1/54 × r2³) = 1/3 × sqrt(1/6 × r2³)

b.

the goal here is

"r2 = ..."

again

36×pi×r1² = 2/3 × pi × r2³

36 × r1² = 2/3 × r2³

3×36 × r1² = 2 × r2³

3×18 × r1² = r2³

54 × r1² = r2³

[tex]r2 = \sqrt[3]{54 \times {r1}^{2} } = 3 \times \sqrt[3]{2 \times {r1}^{2} } [/tex]

c.

r2 is doubled.

so, we have to go back to our equation of a.

r1 = sqrt(1/54 × r2³).

when r2 is doubled, we get

r1 = sqrt(1/54 × (2×r2)³) = sqrt(1/54 × 8 × r2³) =

= sqrt(8) × sqrt(1/54 × r2³)

so, when r2 doubles, r1 has to grow by the factor of sqrt(8) to keep the equality intact.

Answer:

x - 8 = 10

Step-by-step explanation:

The smallest number is 8 so it's subtracting 8. 10 is the difference between the two numbers because it's the answer.

The 8.4 inches length of g and the 79° and 25° measures of the angles ∠G and ∠E, using the law of sines, indicates that the length of the side  EG = f is about 8,3 inches.

The law of sines states that the ratio of the sine of an interior angle of a triangle to the length of the opposite side to the angle is the same for the three sides and angles in a triangle.

Mathematically, the law of sines can be presented as follows;

[tex]\dfrac{a}{sin(A)} = \dfrac{b}{sin(B)} =\dfrac{c}{sin(C)}[/tex]

Where;

a, b, and c are the length of each of the sides of the triangle, and ∠A, ∠B, and ∠C are the measure of each of the interior angles of the triangle.

The details of the triangle ΔEFG, specifying the side g as the side opposite the angle ∠G, and the side f as the side opposite the ∠F we get;

The length of EF = g = 8.4 inches

Length of EG = f

The angle sum property of a triangle indicates that we get;

∠E + ∠F + ∠G = 180°

∠F = 180° - (∠E  + ∠G)

∠F = 180° - (25°  + 79°) = 76°

According to the law of sines, we get;

8.4/(sin(79°) = f/(sin(76°))

f = (sin(76°)) × 8.4/(sin(79°) ≈ 8.3

Answer:

multiply the original price ($299) by the first markup percentage (150%)

299*1.50= $448.50

that is markup price!

then you have to do the sale % (25%)

so you'll multiply your (25%) by your new price ($448.50)

448.50*.25= $112. 125

then you will subtract the sale price ($112.125) by the upcharged price ($448.50)

448.50-112.125= 336. 375

= $336. 38(round off)

Answer:

m=4

Step-by-step explanation:

Answer:

m = 4

Step-by-step explanation:

The shape on the right is 2/3 times smaller than the shape on the left.

This means multiplying the side lengths of the shape on the left by 2/3 will give you the side lengths of the shape on the right.

Take a look.

[tex]9 * \frac{2}{3} = 18/3 = 6[/tex]

[tex]6 *\frac{2}{3} = 12/3 = 4[/tex]

Therefore, the value of the missing side length, m, is 4.

Teo can fill 28 glasses in  4 2/3 pitches of juice.

Teo  has 4 2/3 pitches of juice.

First we write the improper fraction (mixed fraction) as a proper fraction.

4 2/3

= [(4 × 3) + 2] / 3

= (12 + 2) / 3

= 14/3

One glass holds 1/6 of a pitcher.

Let m number of glasses hold 14/3 pitches of juice.

By unitary method,

m × (1/6) =  14/3

To find the value of m we need to divide fractions.

m = (14/3) / (1/6)

m = (14/3) × (6/1)

m = 14 × 2

The easiest way to solve linear equations is to use the elimination method.

A linear equation is an equation that has two variables and when it is graphed it gives a straight line. Linear equations can be graphed according to their slope and y-intercept. The standard equation for a line is y = mx + b, where b is the y-intercept and m is the slope.

To solve linear equations in the easiest and simplest way use the elimination method. In this method, you either add or subtract the equations to obtain an equation in one variable. When the coefficients of one variable are opposites, you add the equations to eliminate a variable and when the coefficients of one variable are equal, you subtract the equations to eliminate a variable.

The equation of the line will be y = -2/3x + 5.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the line passes through points (9, -1) and (6, 1).

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 1 - (-1) / ( 6 - 9 )

Sloe = - 2 / 3

The y-intercept will be calculated as,

y = mx + c

Step-by-step explanation:

The number of adults at the public pool that day is 284 and the number of children is 147.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Let x be the number of adults and y be the number of children who used the swimming pool.

Total number of people used the swimming pool = 431

x + y = 431

Daily price for adults = $2.00

Daily price for children = $1.50

Total amount for admission = $788.50

2x + 1.5y = 788.5

We got two linear equations here :

x + y = 431 and 2x + 1.5y = 788.5

x + y = 431 ⇒ x = 431 - y

Substituting this in second equation,

2(431 - y) + 1.5y = 788.5

862 - 2y + 1.5y = 788.5

-0.5y = -73.5

y = 147

x = 431 - 147 = 284

Hence the number of adults is 284 and the number of children is 147.
