Answer:

ABD and ECD

Step-by-step explanation:

EDC and ADB are vertical angles, so that is the angle we need for the SAS postulate. The markings on each of the corresponding sides is the same, which means we have 2 congruent sides, as well as an angle.

No, Yes, No, Yes

using the laws of exponents

(1)

(4^{3})³ = 4^{9}

4³ × 4³ = 4^{6}

4^{9} ≠ 4^{6} → No

(2)

(3^{4})^4 = 3^{16}

3^{8} × 3^{8} = 3^{16} → Yes

(3)

18^{8} = (6 × 3 )^8 = 6^{8} × 3^{8} ≠ 6^{4} × 3^{4} → No

(4)

20^{3} = (4 × 5 )³ = 4³ × 5³ → Yes

If you purchase 27 guppies, and the increase rate of 35% per year,how many guppies will you have after 3 years
dem82 [27]

Answer:

66

Step-by-step explanation:

<u>year 1: 35% of 27</u>

convert 35% into a decimal :0.35

0.35 x 27= 9.45

27+ 9.45= 36.45 , thats what you have left at the end of year 1

<u>year 2: 35% of 36.45</u>

0.35 x 36.45= 12.7575

36.45 + 12.7575= 49.2075, thats whats left at the end of year 2

<u>year 3: 35% of 49.2075</u>

0.35 x 49.2075= 17.222625

49.2075+ 17.222625= 66.430125, thats whats left at the end of the 3rd year.

you cant have 66.430125 of a guppy so it rounds to a whole number- 66

let me know if this was helpful :)
