The perimeter of uvw is 22 2/1. and vz = 2 1/2. find uw and vw.

UW = 8        VW =10

Step-by-step explanation:

22 2/1 - 4.5 = 18

2 multiplier by the ratio = UW

2.5 multiplied by the rario = VW

ratio=x

2x+2.5x=18

4.5x=18

x=4

RATIO=4

2*4=8  (UW)

2.5*4=10 (VW)

8+10+2+2.5 = 22.5

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
