Answer:
1600 integers
Step-by-step explanation:
Since we have a four digit number, there are four digit placements.
For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.
For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.
For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers
You can set up rations to do this.
So we know that they accept 2:5.
So It would be 180: 450.
The angle at the center of the circle is twice the angle at the circumference.
<h3>What is Circle Theorem?</h3>
The angle in a semicircle is a right angle. Angles that are in the same segment are equal.
As by theorem,
angle in a semicircle is a right angle. Angles that are in the same segment are equal.
Also, opposite angle in a cyclic quadrilateral sums to 180° and the angle between the chord and tangent is also equal to the angle in the alternate segment.
