The equation used to solve this is a= wl (area equals length times width)

Therefore, all you have to do is multiply 12 and 4 to get the area of the rectangle.

12 times 4= 48

The hundreds digit and the ones digit of a three digit number are the same. The sum of its tree digits are 16. If the tens digit
tensa zangetsu [6.8K]
<h2>727</h2>

Step-by-step explanation:

       Let us denote the three digit number by abc, where a is the hundreds digit, b is the tens digit and c is the ones digit.

       Hundreds digit = a = Ones digit = c

       Sum of digits = a+b+c=16

       So, 2c+b=16

       On exchanging tens and ones digit, value increases by 45. So acb is 45 greater than abc.

       acb-abc=45

       100a+10c+b-100a-10b-c=45\\9c-9b=45\\c-b=5

       2c+b=16,c-b=5\\3c=21\\c=7=a\\b=2

∴ Required number is 727

The circular opening of a vase has an inside diameter of 13.5 cm.
Sunny_sXe [5.5K]

Answer:

Area = 143cm^2

Step-by-step explanation:

Given

Shape: Opening of a circular vase

Diameter =13.5cm

\pi = 3.14

Required

Determine the area

This opening implies a circle; hence the area will be calculated using area of a circle.

Area = \pi r^2

Solve for radius (r)

r = \frac{d}{2}

r = \frac{13.5\ cm}{2}

r = 6.75\ cm

Substitute 6.75 for r in Area = \pi r^2

Area = 3.14 * 6.75^2

Area = 143.06625

Area = 143cm^2 --- Approximated

Oksi-84 [34.3K]

Answer:

\large\boxed{x=-4\ \vee\ x=7}

Step-by-step explanation:

x^2-3x-28=0\\\\x^2+4x-7x-28=0\\\\x(x+4)-7(x+4)=0\\\\(x+4)(x-7)=0\iff x+4=0\ \vee\ x-7=0\\\\x+4=0\qquad\text{subtract 4 from both sides}\\x=-4\\\\x-7=0\qquad\text{add 7 to both sides}\\x=7
