Answer:
20 Units
Step-by-step explanation:
RS plus ST equals RT.
Take this visual:
_____/_______________
R S T
5 un 15 un
Using the segment addition postulate, we can tell RS+ST=RT
5+15=20
Hope this helps :-)
The teacher wants to find the variance for the class population. What is the value of the numerator of the calculation of the variance?

Answer:
Original retail price: $35
Step-by-step explanation:
20% off means that the discounted price is equivalent to 80% (100% - 20%) of the retail price.
Calling x the retail price of the scuba mask and snorkel set, then a discounted price of $28 means that this amount of money is 80% of x. Mathematically:
80*x/100 = $28
x = $28*100/80
x = $35

Answer:
25 feet
Step-by-step explanation:
Basically that non-regulation tennis court is a rectangle. You want to know the length of the diagonal. If you draw it on paper, you'll see that this then become 2 triangles... of which you have 2 sides, and are seeking the hypotenuse. So....
H² = A² + B²
H² = 20² + 15² = 400 + 225 = 625
H = 25 feet.
Answer:
The diagonal of a non-regulation tennis court = 25 feet
Step-by-step explanation:
Pythagorean theorem
Hypotenuse² = Base² + Height²
The tennis court is like a rectangle.
We can consider the court as made of two right angled triangle
To find the length of diagonal of court
Here base = 15 feet and height = 20 feet
Diagonal or hypotenuse can be written as,
Diagonal ² = Base² + Height²
= 15² + 20²
= 225 + 400
= 625
Diagonal = √625 = 25 feet
Therefore the diagonal of a non-regulation tennis court = 25 feet
