what is the smallest integer greater than the square root of 85?

Answers

Answer:

the answer is 9.2

Step-by-step explanation:

The radical value √(85) lies between 81 and 100. So, the smallest integer greater than the square root of 85 is 10.

Radical:

Important information:

The given radical value is [tex]\sqrt{85}[/tex].

The perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.

It is clear that,[tex]81<85<100[/tex]

Taking square root on each side, we get

[tex]\sqrt{81}<\sqrt{85}<\sqrt{100}[/tex]

[tex]9<\sqrt{85}<10[/tex]

The value [tex]\sqrt{85}[/tex] lies between 9 and 10.

Therefore, the smallest integer greater than the radical value square root of 85 is 10.

x=-4

y-intercept is when x = 0
-(0)+8y=4
8y=4
y=4/8=1/2

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating

Answers

Answer:

Option D

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:

c² = a² + b²

From the options, option d is the correct option.

For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:

c² = a² + x²

x² = c² - a²

x = √(c² - a²)

Therefore the other leg would be √(c² - a²)

There are 14 girls and 12 boys in a class. What is the ratio of girls to students?

Step-by-step explanation:

There are 14 girls and 12 boys, so there are 26 students in total. Since we are looking for the ratio of girls to students, the ratio will be 14:26. To simplify it, we will divide 14 and 26 by their greatest common factor: 2. We will get the ratio of 7:13.
