Answer:

Divided answer: 180

Scientific Notation Answer: 1.8 x $10^{2}$

Step-by-step explanation:

Dividing

Factor the numerator and denominator and cancel the common factors.

Scientific Notation

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . The sign of the exponent will depend on the direction you are moving the decimal.

Answer:

180

Step-by-step explanation:

$\frac{7,2.10^{-3} }{4.10^{-5} } = \frac{1,8.4.10^{-3} }{4.10^{-3}.10^{-2} } =\frac{1,8}{10^{-2} }= 1,8.100=180$

The quotient rule for exponents states that bm bn=_______, b≠0 . When dividing exponential expressions with the same nonzero b

wariber [46]

Answer:

The quotient rule for exponents states that $b^{m}\div b^{n}=b^{m-n}$ .

When dividing exponential expressions with the same nonzero base, subtract the exponents.

Step-by-step explanation:

Some rules to solve exponents are:

$x^{0}=1$
$(x^{m})^{n}=x^{mn}$
$x^{-n}=\frac{1}{x^{n}}$
$x^{m}\cdot x^{n}=x^{m+n}$
$\frac{x^{m}}{x^{n}}=x^{m-n}$

The quotient rule for exponents states that:

$b^{m}\div b^{n}=b^{m-n}$ .

When dividing exponential expressions with the same nonzero base, subtract the exponents.

Answer:

Therefore, the length of hypotenuse is: 13 units

Step-by-step explanation:

As the given triangle is a right triangle.

We can find the length of hypotenuse using the Pythagoras' Theorem

Let c be the length of hypotenuse

Using Pythagoras' Theorem for the given triangle

$5^2\:+\:12^2\:=\:c^2$

$\mathrm{Switch\:sides}$

$c^2=5^2+12^2$

$c^2=25+144$

$c^2=169$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$c=\sqrt{169},\:c=-\sqrt{169}$

$c=13,\:c=-13$

As the length of hypotenuse cannot be negative. Therefore, the length of hypotenuse is: 13 units

Explain how you can use fraction strips or number lines to show that three fourths and six eighths are equivalent.

Aneli [31]

Answer:

Step-by-step explanation:

Put two rectanagles on top of each other

Divide one into fouth equal peices and one into eight equal peices.

Color 3 peices into the 4 peice shape

Color 6 peices into the 8 peice shape.

The 3/4 peices should be the same length of the 6/8 peices.
