First turn 1/2 and 1/4 in to a decimal we do this by dividing the numerator by the denominator

1/2=0.5

1/4=0.25

Now we just line up the numbers like this

20.00
00.50

Simply and write the answer with positive integral index
Murrr4er [49]

Answer:

3³

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

(a^{m}) ^{n} = a^{mn}

Given

27³ × 3^{-6}

Note that 27 = 3³ , thus

= (3³)³ × 3^{-6}

= 3^{9} × 3^{-6}

= 3^{(9-6)}

= 3³

Give the rate in miles per hour. Round to the nearest tenth. Dev jogs 8 1/2 miles in 1 1/2 hours
andrew11 [14]

Answer:

R=\dfrac{17}{3}\ \text{miles/hour}

Step-by-step explanation:

It is given that,

Distance covered, d=8\dfrac{1}{2}\ \text{miles}

Time taken, t=1\dfrac{1}{2}\ \text{hours}

We need to find the rate in miles per hour. It can be calculated by dividing distance covered and time taken as follows :

R=\dfrac{8\dfrac{1}{2}\ \text{miles}}{1\dfrac{1}{2}\ \text{hour}}\\\\R=\dfrac{\dfrac{17}{2}}{\dfrac{3}{2}}\\\\R=\dfrac{17}{3}\ \text{miles/hour}

Hence, Dev jogs at the rate of \dfrac{17}{3}\ \text{miles/hour}.

What is the smallest whole number larger than the perimeter of any triangle with a side of length 5 and a side of length 19?
vivado [14]

Answer:

48

Step-by-step explanation:

The maximum third side length of a triangle with two sides 5 and 19 is 5+19-1=23. Therefore, the maximum perimeter of a triangle with the two side lengths given is 5+19+23=47.

The smallest whole number larger than this is 48.
