Answer:

46.85

Step-by-step explanation:

let the number be n then doubling it is 2n and

2n + 4 = 97.7 ( subtract 4 from both sides )

2n = 93.7 ( divide both sides by 2 )

n = 46.85

What is the period of the graph y=1/2sin (pix)+3?<br><br> A- 3<br> B- 1/2<br> C-pi <br> D-2
dimaraw [331]

The period is 2.

Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) is a horizontal compression by a factor of 1/pi.  So 2pi·1/pi = 2

The "1/2" and "+3" do not impact the period.  Those just impact the amplitude (vertical aspect) of the graph.

A scale measures weight to the nearest 0.1 pounds. Which is the most appropriate way to report weigh A scale measures weight to
GrogVix [38]

A scale measures weight to the nearest 0.1 pounds

we have to find the most appropriate way to report weigh using this scale

we are given with a few no. of weighs

now lets discuss about weight one by one

200 pounds-it is looking a rounded figure

152 pounds-it is again looking a rounded figure

152.127-it is .not possible because its nearest measure is only 0.1

152.2-it is looking most appropriate as it has one decimal and the given weight scale is also correct to one decimal place
