Make a ratio, then cross multiply.

4/30=x/48

30x=4x48
30x=192
x=6.4

11111nata11111 [884]

Answer:

Area of square  with a side of 2r  = 2(1)  = 2  = 2^2   = 4

Area of circle =  pi ( 1)^2  =  pi

x =  pi / 4   ≈  .79   =  79%

A ball is dropped out a wimdow that is 36 feet high. how long does it take for the ball to hit the ground
Readme [11.4K]
36 feet to metres = 10.97
first find the final velocity
vf^2 = vi^2 + 2ad
vf^2 = 0 + 2(9.81)(10.97)
vf^2 = 215.2314
vf = 14.6708

vf = vi + at
at = vf - vi
t = (vf - vi)/a
t = (14.6708)/9.81
t = 1.4955seconds

Answer:

<h2>84, 42</h2>

Step-by-step explanation:

x,\ y-numbers\\\\\text{The system of equations:}\\\\\underline{+\left\{\begin{array}{ccc}x+y=126\\x-y=42\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad2x=168\qquad\text{divide both sides by 2}\\.\qquad x=84\\\\\\\text{Put the value of}\ x\ \text{to the first equation:}\\\\84+y=126\qquad\text{subtract 84 from both sides}\\y=42

Graph f(x)=2x+1 and g(x)=−x+7 on the same coordinate plane.
Tamiku [17]

Answer:

x = 2

Step-by-step explanation:

To solve the equation, you need to set both functions equal to each other and simplify to find the value of "x".

f(x) = 2x + 1

g(x) = -x + 7

f(x) = g(x)                                              <----- Given equation

2x + 1 = -x + 7                                      <----- Insert functions

3x + 1 = 7                                             <----- Add "x" to both sides

3x = 6                                                  <----- Subtract 1 from both sides

x = 2                                                    <----- Divide both sides by 3
