Answer:

a) 1/2; reduction

b) 5/4; enlargement

Step-by-step explanation:

In each case, the scale factor is CP'/CP. When it is more than 1, the dilation is an enlargement.

Even before you run the numbers, you can tell if it is an enlargement or not. If the dilated figure is larger, P is closer to C than is P'. If P' is closer to C, then it is a reduction.

a) CP'/CP = (4-2)/4 = 2/4 = 1/2 . . . . a reduction

b) CP'/CP = 25/20 = 5/4 . . . . an enlargement

1. A motorboat leaves a harbor and travels at an average speed of 15 mph toward an island. The average speed on the return trip

jenyasd209 [6]

Answer:

30 miles

Step-by-step explanation:

Let d represent the distance to the island. The relation between time, speed, and distance is ...

time = distance/speed

so the total time for the round trip is ...

d/15 +d/10 = 5

Multiplying by 30, we get

2d +3d = 150

d = 150/5 = 30

The island was 30 miles from the harbor.

Aliun [14]

Answer:

1) B. similar

2) D. (4, 2)

Step-by-step explanation:

When a figure is dilated, the shapes will be similar. Reflected is another transformation so that's wrong. Same size and congruent is wrong since that would have to make the dilated size equal which can't since it's contradicting.

B: (4, -2)

Reflection across the x-axis:

(x, y) → (x, -y)

(4, -2) → (x, -y)

(4, 2)

Saiah Copeland sells tennis equipment. He is guaranteed a minimum monthly salary of $1,500 per month plus 5.75% of his total sal

torisob [31]

Answer:

Total sales= 10000

Step-by-step explanation:

Given data

monthly salary=$1500

commission on total sales= 5.75%

gross pay=$2,075

Firstly, let us deduct the salary

2075-1500=$575

so Saiah earned a commission of $575

let the total sales be x

so 5.75% of x= $575

5.75/100*x=576

0.0575x=575

x=575/0.0575

x=10000 sales
