<h3>
Answer: D) pairs 2 and 4</h3>
Pair 2 shows one figure rotated 180 degrees compared to the other, and translated as well. So they are congruent (ie the same).
Pair 4 shows one triangle reflected over the vertical line x = 22 to get the other triangle; which shows they are the same triangle.
The other pairs are not congruent. You can show that the areas of each figure being different is enough to prove they aren't the same figure.
Carly's number is 36.5 and Henry's number is 40.5
Answer:
Step-by-step explanation:
when 1/2 inch equals 4 feet the room is 2.25 inches, then
2 1/4 = 8/4 + 1/4 = 9/4
9/4 inches is the scale distance of the room
each 1/2 inch is 4 feet so divide 9/4 by 1/2 then multiply that by 4 to find the distance of the room
9/4 ÷ 1/2 = 9/4
9/4 * 2/1 = 18/4
18/4 = 9/2
9/2 * 4 feet = 9/2 * 4/1
9/2 * 4/1 = 36/2
36/2=18
the room is 18 feet across
then if the scale is 2/3 of an inch is 4 feet , then
2/3 * 9/4 = 18/12
18/12 = 3 inches is the scale size of Quinto's room
Subtraction: get how many units a number exceeds the other
<span>Division: lets you know how much a number is larger (or smaller) than the other.</span>
Let x be the number of ordinary cars
Let y be the number of SUV's
The difference between the number of ordinary cars and the number of suvs is 17.
So x-y=17 ----> first equation
The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.
ordinary cars = SUV + 77.3% of SUV
x = y + 0.773y
x = 1.773y
Now we solve for y
We plug in x=1.773y in first equation
1.773y - y=17
0.773y = 17
y = 21.9922
Number of SUV's = 22
