When finding the quotient of two fractions, the first thing you should do is to find the inverse fraction of the second fraction, and then switch the division sign to a multiplication sign.
Ex: 4/5 divided by 1/6 becomes 4/5 x 6/1
Then you find the least common denominator, which in this case, is 5. Multiply the 6/1 (as that is the only fraction needed to find the common denominator; the other fraction already has one) by 5/5 to get 5.
Ex: 4/5 x (6/1 x 5/5)
Now multiply the numerators and denominators of 6/1 and 5/5 with each other.
Ex: 4/5 x 30/5
Now multiply the numerators of these fractions by each other.
Ex: 4 x 30
 5
Now: 120
5
If you need to simplify and get a mixed fraction, then do so. But this is just dividing the two fractions to get the "base number".

I hope this helps, please Brainliest me, and have a great day! :D

KFC

Keep the first one
Flick the second one and
Change the division to multiplication

Ex:2/1. /. 3/2

2/1. *. 2/3=4/3=1 1/3

Answer:

5 - 17 - 25 - 42 - 64

Step-by-step explanation:

Given data set:

5, 14, 20, 23, 25, 29, 40, 44, 64

It is already in ascending order.

As per data the 5-number summary is:

Minimum = 5
First quartile = (14 + 20)/2 = 17, the median of the lower half
Median = 25, the middle number as the set comprises of 9 numbers
Third quartile = (40 + 44)/2 = 42, the median of the upper half
Maximum = 64

1. To the nearest degree, find the measure of angle A.

Assoli18 [71]

Answer:

(1) Option A is correct , The measure of angle A = 26°

(2) Option D is correct, The measure of angle B =70°

Step-by-step explanation:

(1)

In a right angle triangle figure-1 ,

* Hypotenuse(H) is always opposite the right angle and it is always the longest side of the triangle.

* Adjacent side (B) is the non-hypotenuse side that is next to a given angle A.

* Opposite side(P) is across from a given angle A.

To find the Angle A we use the Cosine ratio:

Cosine ratio states that the ratio of the adjacent side of a right triangle to the hypotenuse.

By definition of cosine ratio we have;

$\cos A = \frac{B}{H}$ ....[1]

In the figure - 1 we have B = 18 in and H = 20 in

substitute these in [1] to find angle A

$\cos A =\frac{18}{20} =\frac{9}{10} = 0.9$

$A = cos^{-1} (0.9)$

⇒ $A \approx 26^{\circ}$

therefore, the measure of angle A is, $26^{\circ}$

(2)P

In figure -2

Find the measure of angle B.

First find the side BC, using Pythagoras theorem;

Pythagoras theorem states that in the right angle triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Apply Pythagoras theorem in rt. angle ABC;

$AB^2 = AC^2+BC^2$
