Step-by-step explanation:
such a scale factor applies to all sides and lines.
we see that DE is 12 units, and AB is 4 units.
so,
12×f = 4
f = 4/12 = 1/3 is the scale factor
control : check the other side
FE = 6 units
6 × 1/3 = 2
so, the corresponding side in the small triangle must be 2 units long.
and indeed, CB is 2 units long. all correct.
Answer:
C) 125°
Step-by-step explanation:
Supplementary angles add to 180 degrees. Complementary angles add to 90
An angle's complement is 35°.
35+x =90
Subtract 35 from each side
35 -35+x = 90-35
x = 55
We want to find the supplement of this angle
55+y = 180
Subtract 55 from each side
55-55+y = 180-55
y= 125
The angle is 55 so its supplement is 125
Total distance the rover need to travel is 
.
<u>Step-by-step explanation:</u>
We have , Garne Problem med . A rover needs to travel mile to reach its destination traveled mile. a rover needs to travel 5/8 mile to reach its destination it has already travel 3/8 miles . We need to find that how much farther does the rover need to travel , Let's do it step by step:
First , rover has already traveled 3/8 miles , Let total distance to be traveled by rover is D :
⇒ 
, where d is distance left to cover .
Now, rover need to travel 5/8 miles more to reach destination :
⇒ , where d is distance left to cover , So 
⇒
⇒ 
⇒ 
⇒ 
⇒
∴ Total distance the rover need to travel is .
Round each number to the nearest hundred.
212 = 200.
314 = 300.
How much more marbles does Peck have?
314 - 212 = 102.
That is your answer. Hope this helps!
