Answer:

\frac{5g}{8g} OR 5g : 8g

Step-by-step explanation:

Also a ratio can also be represented by a fraction; \frac{40g}{64g}

So to make the ratio to the simplest form we have to divide by a number that can divide both number.

40g : 64g

We can start dividing by 2 which will give us;

20g : 32g

\frac{20g}{32g}

Now we can divide by 2 again since it can divide both numbers which will give us;

10g : 16g

\frac{10g}{16g}

We can still divide by 2 since it can divide both numbers which will give us;

5g : 8g

\frac{5g}{8g}

Since no numbers can divide 5 and 8 equally that is our answer.

Also, \frac{5g}{8g}

22/7 divided by 11/44
Alecsey [184]
You swap the second number over.
then multiple the numbers instead.
22/7 x 44/11
22 x 44= 968
7 x 11 = 77
968/77 can be simplified to 12 14/77

PLEASE WILL GIVE 50 POINTS PLEASE ANSWER ​

Answer:

AB = 75

BC = 60

AC = 45

m∠A = 53°

m∠B = 37°

m∠C = 90°

Step-by-step explanation:

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse (the side opposite the right angle)

Given:

\sf \tan(A)=\dfrac{60}{45}

Therefore:

  • side opposite angle A = BC = 60
  • side adjacent angle A = AC = 45

To find the length of AB (the hypotenuse), use Pythagoras’ Theorem:

a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

⇒ AC² + BC² = AB²

⇒ 45² + 60² = AB²

⇒ AB² = 5625

⇒ AB = √5625

⇒ AB = 75

To find m∠A:

\implies\sf \tan(A)=\dfrac{60}{45}

\implies\sf A=\tan^{-1}\left(\dfrac{60}{45}\right)

\implies\sf A=53^{\circ}\:(nearest\:degree)

m∠C = 90° (as it is a right angle)

The interior angles of a triangle sum to 180°

⇒ m∠A + m∠B + m∠C = 180°

⇒ 53° + m∠B + 90° = 180°

⇒ m∠B = 180° - 53° - 90°

⇒ m∠B = 37°

The points at which a quadratic equation intersects the x-axis
skelet666 [1.2K]

The points at which a quadratic equation intersects the x-axis are referred to as   x intercepts or zeros or roots of quadratic equation

Given :

The points at which a quadratic equation intersects the x-axis

The points at which the any quadratic equation crosses or touches the x axis are called as x intercepts.

At x intercepts the value of y is 0.

So , the points at which a quadratic equation intersects the x-axis is also called as zeros or roots of the quadratic equation .

The points at which a quadratic equation intersects the x-axis are referred to as   x intercepts or zeros or roots of quadratic equation
