Step-by-step explanation:

A <u>parallelogram</u> is a quadrilateral with parallel opposite sides. The main property of a parallelogram is that the opposite sides of the parallelogram are congruent.

1. Sides AB and CD are congruent, then

$4x=18\\ \\x=\dfrac{18}{4}=4.5$

2. Sides AD and BC are congruent, so

$\dfrac{1}{3}x=7\\ \\x=7\cdot 3=21$

3. Sides AD and BC are congruent, so

$x+4=15\\ \\x+4-4=15-4\\ \\x=11$

8.3 x 10 to the 3rd power

masha68 [24]

If your looking at a number to a power (in this case, 3 [cubed]), you multiply the base by the exponent. I would start with the 10 - 10x10x10 = 1,000

Next, multiply your answer by 8.3. You now have 8,300 :)

What is the surface area of a cone with a diameter of 28 cm. and height 22 cm in terms of Ï.

Svetlanka [38]

To find the surface area of a cone, use this formula.

pi (r) (r + [square root of h^2 plus r^2] ) substitute

h = height = 22 r = radius = 28/2 = 14 [ ] = sq. root

pi (14) (14 + [ 22^2 + 14^2 ]) solve exponents

pi (14) (14 + [484 + 196]) add

pi (14) (14 + [680]) solve square root

pi (14) (14 + 2[170]) add

pi (14) (40.0768) multiply

pi (561.075) is about 561.1 rounded to nearest tenth

So the answer is C. 561.1pi cm^2

Answer:

Step-by-step explanation:

$x,\ y-the\ numbers\\\\\text{The sum of four times a number and five times another number is -28:}\\\\4x+5y=-28\\\\\text{The sum of nine times the first number and two times the second number is 11:}\\\\9x+2y=11\\\\\text{We have the system of equations:}\\\\\left\{\begin{array}{ccc}4x+5y=-28&\text{multiply both sides by2}\\9x+2y=11&\text{multiply both sides by (-5)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}8x+10y=-56\\-45x-10y=-55\end{array}\right}\qquad\text{add both sides of the equation}$

$.\qquad-37x=-111\qquad\text{divide both sides by (-37)}\\.\qquad\qquad\boxed{x=3}\\\\\text{Put the value of x to the first equation:}\\\\4(3)+5y=-28\\12+5y=-28\qquad\text{subtrac 12 from both sides}\\5y=-40\qquad\text{divide both sides by 5}\\\boxed{y=-8}$
