Find the area of parallelogram ABCD given mA = 30 and the following measures. AB = 6ft ; AX = 3 [square root] 3, A = ?
The area of the given parallelogram is: 9√3 sq. feet.
What is a parallelogram?A parallelogram is a simple quadrilateral with two sets of parallel sides in Euclidean geometry. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
Area of a parallelogram = Base of the Parallelogram * Height
Now, given:
A parallelogram ABCD,
AB = 6 feet, AX = 3√3. Angle A = 30°
To find: Area of the Parallelogram ABCD.
Finding: Here, AB = 6 feet = base
For height,
Height = perpendicular distance from X to AB
= AX(sinA)
Height = 3√3 (sin30) = 3√3 / 2
Thus, area of the parallelogram = [tex]\frac{3\sqrt{3}}{2}\times6= 9\sqrt{3}sq. feet.[/tex]
Hence, The area of the given parallelogram is: 9√3 sq. feet.

A cube has a volume of 197 meters cubed (197 m3) What is the approximate value of one edge of the cube? The approximate value of one edge of the cube is meters. Round your answer to the nearest hundredth. What is the approximate area of one face of the cube? The approximate area of one face of the cube is meters. Round your answer to the nearest hundredth.
The edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively
How to determine the valueThe formuka for the volume of a cube is expressed as;
Volume = a^3
Where 'a' is the length of it's edge
From the information given, we have that the volume of the cube has a value of 197 cubic meters.
Now, substitute the value of the volume
We have;
197 = a^3
Take the cube root of both sides
a = 5. 82 meters
The formula for area of the face of a cube is given as;
Area = 6a ^2
Area = 6(5.82)^2
Area = 6(33. 85)
Area = 203 square meters
Thus, the edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively

The angle shown has the same measure as an angle drawn on paper. Order the steps for copying the angle from the paper using a compass and straightedge.
The order of the steps for copying the angle from the paper using a compass and a straight edge are;
5. Label the original angle as ‹A. On a separate piece of paper, draw a horizontal ray directed to the right, using the straight edge. Label the left endpoint D
4. Draw an arc centered at the vertex A that passes through both sides of ‹A using the compass. Label the points of intersection B and C.
1. Using the same compass setting, draw an arc centered at point D that intersects the ray and looks like the arc through B and C. Label the intersection of the arc and the ray as E.
3. Adjust the compass to the length BC. Draw an arc with radius BC centered at point E that intersects the arc through E. Label the point of intersection F.

Alejandro and some friends are going to the movies. At the theater, they sell a bag of popcorn for $3.50 and a drink for $4. How much would it cost if they bought 3 bags of popcorn and 8 drinks? How much would it cost if they bought p bags of popcorn and d drinks?
Total cost, 3 bags of popcorn and 8 drinks:______
Total cost, p bags of popcorn and d drinks:______
Answer:
Step-by-step explanation:
Using a proportional relationship, the costs are given as follows:
3 bags of popcorn and 8 drinks: $42.05.p bags of popcorn and d drinks: C(p,d) = 3.35p + 4d.What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
A proportional relationship may also involve multiple variables, as is the case in this problem, in which the cost is a function of the number of bags of popcorn p and the number of drinks d.
The constants are the prices of each product, hence the function for the total cost of p bags of popcorn and d drinks is given by:
C(p,d) = 3.35p + 4d.
Hence, for 3 bags and 8 drinks, the cost is:
C(3,8) = 3.35(3) + 4(8) = $42.05.

a swimming pool has two pipes coming in. one fills the pool in four hours, the other in six hours. an outlet pipe empties the pool in five hours. the outlet pipe is accidentally left open. in how many hours is the pool full?
The pool is full for 4 hrs.
Add the rates of filling of the 2 filling pipes and
subtract the rate of draining of the emptying pipe;
1st pipe's rate: ( 1 pool filled ) / ( 3 h);
2nd pipe's rate: ( 1 pool filled ) / ( 6 h );
3rd pipe's rate of emptying: ( 1 pool emptied ) / ( 4 h);
Let t = the time in hrs to fill the pool with all 3 pipes open
1/3+16-1/4 = 1/t;
Multiply both sides by 24t;
