Answer:
D, the bottom right
Step-by-step explanation:
A dilation by a factor of 3 would have values 3 times larger. So the original which has side lengths 2, 6, and 3 would become
2*3 = 6
6*6 = 36
3*6 = 18
The figure which has these measurement is D or the bottom right.
Answer:
Step-by-step explanation:
Since the two triangles are congruent, all their angles are as well.
So you can set 4y-10 = 3y+5 since they are the same angles.
Now solve the system by putting the y's on the left side and coefficients on the right side:
y=15.
Answer:
1.9 miles.
Step-by-step explanation:
John jogs 2 7/10 miles to the park. Marsha jogs 4/5 miles to the park.
Convert the fractions into decimals:
2 7/10 = 2.7
4/5 = 0.8
Subtract '0.8' from '2.7':
John should jog 1.9 miles farther than Marsha.
Hope this helps.
