Split in half 20 squared + 10 squared
then find the square root of the answer
10-/5
I'm sorry, I'm not sure, but try your best!
If you illustrate the problem, the parallelogram will look like this with the following coordinated (see picture).
The k must be the x-axis while h must be the y-axis. The y-coordinate of the unknown must be j because it is aligned with the upper right corner. By definition, a parallelogram is a quadrilateral with two equal, parallel sides. Hence,you also have two sets of equal angles. It also means that the distance of the upper and bottom corners of the left side and the right side are equal. Through symmetry, the x-coordinate is the distance between h and k.
Thus, the unknown coordinates are
(h-k,j)
<span>let 'x' be the amount for cat's food and medication
'y' be the amount for dog's food and medication.
since the cost of food and medication for a cat is $5 less than two-thirds of the cost of food and medication for a dog then you'll have the equation as:
x = 2/3y - 5 ------equation 1
knowing that the total is 195 and there are 6 cats and a dog then,
6x + y = 195 -----equation 2
substitute equation 1 to equation 2
6x + y = 195
6(2/3y - 5) + y = 195
distribute 6 to the quantity
4y - 30 + y = 195
4y + y = 195 + 30
5y = 225
y = $45</span>
Answer:
72 sq. inch.
Step-by-step explanation:
9 inches in feet is 9/12 = 0.75 feet.
We can set up a ratio to figure out the width of the scale drawing.
This means <u>"if 36 feet is 0.75 feet in drawing, how much (let that be x) is 32 feet?"</u>
<u />
let's cross multiply and solve for x:
<em>So width is 2/3 feet and length is 0.75 feet.</em>
<em>Converting back to inches (since we need the area in sq. inches):</em>
<em>2/3 feet = 2/3 * 12 = 8 inches, and</em>
<em>0.75 feet = 0.75 * 12 = 9 inches</em>
<em />
<em>Hence, area is 8 * 9 = 72 sq. inches.</em>
