Number of Children = 165

Number of Adults = 182

Step-by-step explanation:

Let x be the number of children and y be the number of adults

Then according to given statements

x+y=347\ \ \ \ \ Eqn\ 1\\and\\1.75x+2.50y=743.75\ \ \ \ Eqn 2\\From 1:\\x=347-y\\Putting\ this\ in\ equation\ 2\\1.75(347-y)+2.50y=743.75\\607.25-1.75y+2.50y=743.75\\0.75y+607.25=743.75\\0.75y=743.75-607.2\\0.75y=136.5\\

y=\frac{136.5}{0.75}\\y=182\\Putting\ y=182\ in\ eqn\ 1\\x+182=347\\x=347-182\\x=165

Number of Children = 165

Number of Adults = 182

A line passes through the point (5,-11) and has a slope of -2 Find an equation of this line.
Vsevolod [243]

Formula: y = mx + b

m being the slope

Slope given: -2, plug it in

Y = -2x + b

Now find y intercept (b)

Plug in the point (5,-11)

-11 = -2(5) + b

-11 = -10 + b, b = -1

Solution: y = -2x -1

Kobotan [32]

Answer:

Step-by-step explanation:

1 revolution will equal 360 degrees

Because of that 30,000 revolution would be 10,800,000 degrees

100,000 rev would equal 36,000,000 degrees

The range through which the composite flywheel rotates in one minute be denoted by ' F ' . (1.08 x 107)° F (3.6 x 107)°

Plz help , due in 5 mins ​
Grace [21]

Answer:

option a) 30 : 19

Step-by-step explanation:

Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}

<em><u>Ratio of length to width:</u></em>

      \frac{15}{2} : \frac{19}{4}<em><u></u></em>

    =\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19
