An estar escrito en la forma n / 1. Por ejemplo, 5 = 5/1 y, por tanto, 5 es un número racional. Sin embargo, números como 1/2, 45454737/2424242 y -3/7 también son racionales, ya que son fracciones cuyo numerador y denominador son números enteros.

8. In the diagram, the measure of the arc from A to B not

Deffense [45]

The measure of the angle ∠ABC will be 40 degrees. Then the correct option is B.

<h3>What is a circle?</h3>

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

In the diagram, the measure of the arc from A to B not passing through C is 80 degrees.

Then the measure of angle ACB will be

We know that Angles subtended by the very same arc at any position on the circular path are half of the angles subtended by the very same arc at the centre.

Then we have

2∠ABC = ∠AOB

2∠ABC = 80°

∠ABC = 40°

Explain how knowing 1+7 helps you find the sum for 7+1

Alex Ar [27]

Ex:
1+7=8
And
7+1=8

1/4 foot every 3/4 hour how many feet in one hour

RUDIKE [14]

For this case we propose a rule of three:

$\frac {1} {4}$ foot -------------> $\frac {3} {4}$ hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

$x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}$

So, we have $\frac {1} {3}$ foot every hour.

Answer:

$\frac {1} {3}$ foot every hour
