Answer:

\frac{37}{8}

4\frac{5}{8}

135

Step-by-step explanation:

Four and five eighths is given as:

4\frac{5}{8}

This is a mixed fraction. It has the whole number (4) and the fraction part (5/8)

As an improper fraction:

= 8 (4) + 5

= 37

= \frac{37}{8}

An improper fraction has a large numerator than denominator.

LCM of 27 and 45

The expression for 27 in terms of prime factors  = 3 × 3 × 3

The expression for 45 in terms of prime factors  = 3 × 3 × 5

The LCM is derived by combining the highest powers of 3 and 5 which is:

LCM = (3 × 3 × 3)× 5

       = 135

What is the quotient of -8x∧6 over 4x∧-3 ??
Allushta [10]

Answer:

-2x^{9} is the quotient

Step-by-step explanation:

We have two expression -8x^6 and 4x^{-3}

We need to find quotient of this expression using exponent law.

First we write as quotient form,

\Rightarrow -\dfrac{8x^6}{4x^{-3}}

\Rightarrow -2x^{6-(-3)}                        (x^m\div x^n=x^{m-n})

\Rightarrow -2x^{6+3}

\Rightarrow -2x^{9}

Thus, -2x^{9} is the quotient of -8x^6 and 4x^{-3}.

Leah claims that these figures are not similar. When she compared the heights, she wrote 27. Then she compared the bases and got
Flauer [41]

Answer:

<h2>Leah is actually wrong, because those rectangles are similar.</h2>

Step-by-step explanation:

Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.

In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.

\frac{21}{6}=3.5

\frac{7}{2}=3.5

As you can observe, both ratios are equal.

Therefore, those rectangles are congruent.

Answer:

About 110.6

Step-by-step explanation:

The sine of an angle is the length of the opposite side divided by the length of the hypotenuse.

\sin 19= \dfrac{36}{x} \\\\x=\dfrac{36}{\sin 19}\approx 110.6

Hope this helps!
