R = 3cm
V = 900 cm^3

V = pi * r^2 * h / 3
900 = (22/7) * 3^2 * h/3
h = (900*3*7) / 22 / 3^2
h = 18900 / 22 / 9
h = 95.45 cm

What is the value of y?
Amiraneli [1.4K]

Answer:

\boxed{D. \: 40\degree}

Step-by-step explanation:

<em>Angle sum property of triangle states that the sum of interior angles of a triangle is 180°</em>

So,

=  > 2y \degree + (y + 10)\degree + 50\degree = 180\degree \\  \\  =  > 2y\degree + y\degree + 10\degree + 50\degree = 180\degree \\  \\  =  > 3y\degree + 60\degree = 180\degree \\  \\  =  > 3y\degree = 180\degree - 60\degree \\  \\  =  > 3y\degree = 120\degree \\  \\  =  > y =  \frac{120\degree}{3\degree}  \\  \\  =  > y = 40\degree

Dmitriy789 [7]

1 liter of petrol in London costs £1.029

Since 1 gallon consist of 3.7854 liters, the cost of 3.7854 liters is calculated as:

Cost of 1 gallon of petrol in London = 3.7854*1.029 =£3.8951766

Next, we convert the pounds (£) to dollar($)

Since the exchange rate is 1$ =£ 0.497

£3.8951766 in $ = £3.8951766/£ 0.497 = 7.837$

The price of London petrol in dollars ($) per gallon =$7.84 (Rounded to nearest cents)

Simplify 3 over 2 x 3 over 2 exact answer
nikitadnepr [17]

ANSWER : 9 over 4

or 2 and 1/4

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*3 over 2 x 3 over 2 is 3/2 x 3/2* << this is for me to remember

Okay so multiplying fractions means for us to multiply across. That means if we line the fractions, we multiply. Like this

 3     x     3

-----         -----                3 times 3 is = 9

 2     x     2                  2 times 2 is = 4

9 over 4 is the same thing as 2 and 1/4  << FRACTION    

                                                ^^      

                                           WHOLE

Hope I helped (:
