28:20
Step-by-step explanation:
you just multiply 5 by 4 because 20 divided by 4 is 5 and then multiply 7 by 4
Considering the given area of the square, it is found that it's side length is an irrational number.
<h3>What is the missing information?</h3>
This problem is incomplete, but researching it on a search engine, it asks if the side length of the square of area 89 cm² is rational or irrational.
<h3>What is the formula for the area of a square?</h3>
The area of an square of side length s is given by s squared, as follows:
A = s².
In this problem, the area is of 89 cm², hence:
s² = 89.
s = sqrt(89).
The square root of 89 is a non-exact root, hence it cannot be represented by fraction and is an irrational number.

Answer:
$52.71
Step-by-step explanation:
Today's price= $58.63
Yesterday's price= y
Difference= $5.92
y+5.92 = 58.63
y = 58.63 - 5.92
= $52.71
3. Hypotenuse 8m, the usual 45/45/90 triangle sides in ratio 1:1:√2. So we're 8/√2 = 4√2 from the wall.
Answer: 4√2 meters
4. 30/60/90 right triangle, sides in ratio 1:√3:2. Hypotenuse 50m, we're after the side opposite 60, so 50/√3 = (50/3) √3
Answer: (50/3)√3 meters
5. 45/45/90 again, ratio 1:1:√2. Leg 3 cm so hypotenuse 3√2
Answer: 3√2 cm
6. The altitude divides the triangle into two 30/60/90 triangles, ratio 1:√3:2.
The side length s of the original equilateral triangle is the hypotenuse and the altitude h is the long leg, so h= (√3/2) s.
Answer: a. 3√3 cm b. 2√3 cm c. 5√3 cm
