Answer:

1

Step-by-step explanation:

Given expression:

27 \cdot \left(\left(3^3\right)^{-1}\right)

Following the <u>order of operations</u>, carry out the operations inside the parentheses first:

\implies 27 \cdot \left(\left(3 \cdot 3\cdot 3\right)^{-1}\right)

\implies 27 \cdot \left(27^{-1}\right)

\textsf{Apply exponent rule} \quad a^{-n}=\dfrac{1}{a^n}:

\implies 27 \cdot \left(\dfrac{1}{27^1}\right)

\implies 27 \cdot \left(\dfrac{1}{27}\right)

Convert 27 to a fraction:

\implies \dfrac{27}{1} \cdot \dfrac{1}{27}

Cross cancel the common factor:

\implies \dfrac{\diagup\!\!\!\!\!27}{1} \cdot \dfrac{1}{\diagup\!\!\!\!\!27}

\implies \dfrac{1}{1}

\implies 1

How to find the surface area
Stolb23 [73]

Answer:

158 in²

Step-by-step explanation:

<u>Surface area</u>

A = 2·(l·w + l·h + w·h)

= 2·(3in·8in + 8in·5in + 3in·5in)

= 2·(24in² + 40in² + 15in²)

= 2·(79in²)

A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?
mote1985 [20]

Answer:

36

Step-by-step explanation:

We need to find the LCM of the two numbers because we need to know the lowest number that 12 and 9 are both in.

12 × 1 = 12

12 × 2 = 24

12 × 3 = 36

12 × 4 = 48

9 × 1 = 9

9 × 2 = 18

9 × 3 = 27

9 × 4 = 36

We can see that 36 is the lowest number that occurs both in 12 and 9 so the blue and red light will both link at 36 seconds
