Answer:
181
Step-by-step explanation:
Area of a semicircle: 1/2 (pi • r^2)
1/2(3.14 • 100)
1/2 ( 314 )
157
Triangle:
(6 • 8) ÷ 2
48 ÷ 2
24
Add the area of the triangle & semicircle together: 157 + 24 = 181
Hope this helps! Have a great day!
Answer: (x + 2) × (x + 1)
Step-by-step explanation:
x^2 + 3x + 2
x^2 + 2x + x + 2
x(x + 2) + 1(x + 2)
(x + 1) (x + 2)
The cost of each Piano Lesson = $30
If there are x lessons, the total cost of lessons can be expressed as 30x.
Since the number of lessons cannot be negative, the value of x can be 0 or greater than 0, where x=0 shows no lesson.
For 1 lesson, x = 1
So the cost will be = 30(1) = $30
In ordered pair we can write it as (1, 30)
If we consider there is an option to attend half portion of a lecture, then for 1 and half lectures, x = 1.5
So, the cost for 1.5 lectures will be = 30(1.5) = $45
In ordered pair we can write it as (1.5, 45)
For 3 lesson, x = 3
The cost of 3 lessons will be = $90
In ordered pair we can write this as (3, 90)
So, from the given options, only following 2 ordered pairs satisfy the given conditions:
1) (1,30)
2) (3, 90)
I think its 11 for its absolute value
Well on answer could be $238-$28=210 divided by 3 = $70 each
also another one is $208-$28=180 and then if u divide $180 by 3 u will get a awser of $60 each
