Joianie beleives that you cannot use cross products to solve the proportion 50/3 = 75/x for x. She says
BigorU [14]

Answer:

4.5 It doesn't come out evenly, but cross products do work.

Step-by-step explanation:

She is not correct.

50 * x = 3 * 75              Combine the right

50x = 225                    Divide by 50

x = 225/50

x = 4.5

A line passes through (2, 8) and (4, 12). Which equation best represents the line? y = 1 over 2 x 6 y = 2x 7 y = 2x 4 y = 1 over
nalin [4]

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

Given information-

The point through which the line passes are (2, 8) and (4, 12).

To find the equation of the line, the standard form of the equation of the line must be obtained.

<h3>Equation of the line</h3>

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

The standard form of the equation of the line can be given as,

(y-y_1)=\dfrac{y_2-y_1}{x_2-x_1} (x-x_1)

Where (x_1,y_1) and (x_2,y_2) are the points through which the line passes.

Thus the equation of the line which passes through the points (2, 8) and (4, 12) can be given as,

(y-8) &=\dfrac{12-8}{4-2} (x-2)\\(y-8) &=\dfrac{4}{2} (x-2)\\2y-16 &=4x-8\\2y &=4x-8+16\\

Divide by 2 both the side,

y=2x-4

Thus the equation of the line which passes through the points (2, 8) and (4, 12) is,

y=2x-4

Hence the option 3 is the correct option.

Can anybody do all of number 1??
MAXImum [283]

Answer:

You use the formulas for the shapes

Cylinder= 2×π×r×h+2×π×r²               π×r²×h

Cone= \pi*r(r+\sqrt{ h^{2} +r^{2}} )           π×r²×\frac{h}{3}

Square Prism= 2×a²+4×a×h                       a²×h

                            ↑a=base edge

Step-by-step explanation:

                           Surface Area  Volume

Cylinderical Head   ≈282.74                   ≈314.16  

Conical Hat                     ≈170.13                     ≈78.54

Right Cylinder Torso      ≈471.24                     ≈785.4  

Right Cylinder Arm         ≈56.55                      ≈25.13

Square Prism Leg           =224                           =192
