The original figure will be enlarged by the dilation.

The image and the pre-image will be similar figures.

The corresponding angles of the figures will be congruent.

<h3>What is dilation?</h3>

Dilation is the increase or decrease in the size of a figure by a scale factor k. Dilation produces similar shapes.

If k > 1, this is an enlargement, if k < 1, it is a reduction.

Trevor is dilating a figure on the coordinate plane by a scale factor of 9/5 (>1). Hence:

The original figure will be enlarged by the dilation.

The image and the pre-image will be similar figures.

The corresponding angles of the figures will be congruent.

inna [77]

The population of these two cities combined in scientific notation is 11.9 x $10^{6}$

Step-by-step explanation:

1a. Population of NYC is 8.1 x $10^{6}$

1b. Population of LA is 3.8 x $10^{6}$

2.To find total population of the two cities combined,

2a. Add population of NYC and LA

Total population = NYC's population + LA's population

Total population = (8.1 x $10^{6}$ ) + (3.8 x $10^{6}$ )

2b. Take $10^{6}$ common

Total population = $10^{6}$ * (8.1 + 3.8)

Total population = $10^{6}$ * 11.9

Therefore, the population of these two cities combined in scientific notation is 11.9 x $10^{6}$

199 *0.05 = 9.95

4750 * 0.06 = 285

99.50 * 0.047 = 4.68

19.88 * 0.069 = 1.37

8.95 * 0.072 = 0.64

14.27 * 0.068 = 0.97

544.38 * 0.042 = 22.86

7.49 * 0.081 = 0.61

28.56 * 0.075 = 2.14

14.98 * 0.049 = 0.73

I NEED HELP!!

Tpy6a [65]

Answer:

Step-by-step explanation:

Step 1: Find the total fraction of raisins he gave to his brothers

Step 2: Find the lowest common multiple(Lcm) of 6 and 4

Lcm of 6 and 4 = 12

Step 3: Add the fractions

= $\frac{2+ 3}{12}$

= $\frac{5}{12}$

Step 4: To find the fraction that he kept, you will subtract the total fractions he gave his brothers from 1.

$1 - \frac{5}{12} \\= \frac{12-5}{12} \\= \frac{7}{12}$

Final answer

The fraction that he kept = $\frac{7}{12}$
