A and b are positive integers and a–b = 3. Evaluate the following: 27^ (1/3 b)/9^ (1/2 a)

maxonik [38]

Answer:

1/27

Step-by-step explanation:

27^(b/3)/9^(a/2) = (27^(1/3))^b/(9^(1/2))^a = (3^b)/(3^a) = 3^(b-a)

= 3^(-(a-b)) = 3^-3 = 1/3^3 = 1/27

Pls help me with this!

stira [4]

Answer:

See below.

Step-by-step explanation:

1.

(a) < PMR

(b) < QMR

(c) < QMN

(d) < RMN

2. m < C = 4x - 6

= 4(25) - 6

= 100 - 6

= 94 so < C is obtuse.

3. 8x + 2 = 90

8x = 90 - 2

8x = 88

x = 11.

4.

(a). < DBA and < DBC are right angles (90 degrees) because BD is perpendicular to AC.

(b) < DBA and < DBC are adjacent and they share the ray BD.

(c) < DBe and < ABE are complementary.

(d) < DBA and < DBC are supplementary

(e) 90 - 40 = 50 degrees

(f) 180 - 40 = 140 degrees.

(g) As the angles are complementary

3x + 2 + 4x + 4 = 90

7x = 90 - 2 - 4

7x = 84

x = 12.

Anybody know how to do this? I need Help Now!!!!!

Hi there!

The answer is
$x \leqslant - 5$

We have the following inequality.
$- 6x \geqslant 30$

We can divide both sides by -6, but because we divide by a negative number, we must flip the sign.

$x \leqslant 30 \div - 6$
$x \leqslant - 5$
