Answer:
B
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply each of the coordinates by 4 , that is
A (0, 10 ) → A' (4(0), 4(10) ) → A' (0, 40 )
B (8, 6 ) → B' (4(8), 4(6) ) → B' (32, 24 )
C (4, 2 ) → C' (4(4), 4(2) ) → C' (16, 8 )
Answer: 0.09 hours
Step-by-step explanation:
You are owed $1.76 in overtime pay.
The hourly rate for overtime is $19.50 per hour.
To find the number of hours owed, you need to divide the amount owed by the amount owed per hour.
The number of hours you are owed is therefore:
= Amount owed / Amount owed per hour
= 1.76 / 19.50
= 0.09 hours
3+2x=y
6y=5x+4
6(3+2x)=5x+4
18+12x=5x+4
14+12x=5x
14=-7x
-2=x
the number is -2
Answer:
20+16= 36
Step-by-step explanation:
Answer:
Second option, scale factor is 2.5
Step-by-step explanation:
We see that ∠B ≅ ∠E and ∠C ≅ ∠F, therefore, ΔABC ~ ΔDEF by the AA Similarity for Triangles Theorem which states that if two pairs of corresponding angles are congruent in two triangles, then those two triangles are similar. To find the scale factor, all we have to do is DF / AC = 5/2 or 2.5.
