Answer: 60
Step-by-step explanation:
You have to use Pythagorean Theorem because the other side is not listed of the triangle
Pythagorean Theorem: a² + b² = c²
a² + 20² = 25²
a² + 400 = 625
625-400 = a²
a² = 225
Find the square root of 225 to find the missing length
= 15 (this is the missing length for QS
To find the perimeter, add all the sides...
15 + 20 +25 = 60

Answer:
The cost of the lessons taken
Step-by-step explanation:
Let
y -----> the total paid for the baseball bat and the lessons
c ----> the number of lessons
we have
y=25c+75
This is a linear equation in slope intercept form
y=mx+b
where
b=$75 -----> the price of he baseball bat (y-intercept)
m=25 $/lesson ----> the slope of the linear equation
therefore
25c represent the cost of the lessons taken
Answer:
Step-by-step explanation:
All numbers in scientific notation or standard form are written
,
where m is a number between 1 and 10.
Parallelograms and trapezoids always do.
(Note: "Parallelograms" includes rectangles, squares, and rhombussesses.)
Any polygon with more than 4 sides <u>can</u> have at least one pair of parallel sides,
but it's not guaranteed.
