Answer:
4 2/3 cm
Step-by-step explanation:
When we have area, it is the related to the scale factor by the scale factor squared
Area large/ area of small = 49/9
Take the square root
sqrt(49/9) = 7/3
The scale factor is 7/3 large to small
The small side is 2 cm
large 7 x cm
-------- = ------ = -----------
small 3 2 cm
Using cross products
7*2 = 3x
Divide by 3
14/3 = 3x/3
14/3 = the large side
4 2/3 cm
Dividing 1 1/4 hrs by 5 days results in the unit rate:
1 1/4 hrs 5/4 hrs
----------- = ---------------- = 1/4 hr per day
5 days 5 days
Answer:
y = 38, x = 90, x = 10, u = 6.2, w = 52, and v = 7.9
Step-by-step explanation:
Since the triangles are congruent, the angle and side lengths are also congruent. (CPCTC) Therefore, y = 38, x = 90, x = 10, u = 6.2, and v = 7.9. For w, we need to use the sum of angles in a triangle. So, we do 180 - 38 - 90 = w
w = 52.
Answer:
1: 8 2/5
Step-by-step explanation:
4x5=20+3=23
3x5=15+4=19
23+19=42
42/5= 8 2/5
