She starts with 40 points already so you add in those 40 then since she gets 12.5 points per visit that is your x, so you set that as greater than or equal to 175
Answer:
The area is 48 cm^2
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 b*h
A = 1/2 * 8cm*12cm
A = 1/2 *96cm^2
A = 48 cm^2
The area is 48 cm^2
Answer:
The correct answer is -
a. 4.5 inches.
b. side or arm (a)
c. (a) or 4.5, and 18
d. (d) 4.5, and 14.1428
e. 22/7 × r^2 = 15.90
Step-by-step explanation:
Given :
Radius or r = 2 ¼ inches
Solution:
a. the diameter of the circle -
d = 2r
= 2 ¼ *2
= 2.25*2
= 4.5
b. The diameter of the circle is the same length as one side or arm of the square which is
a = d = 4.5
c. The perimeter of the square
P = 4a = 4d = 4*4.5 = 18
d. Perimeter of the circle =
2πr = πd = (22/7)*4.5
= 14.1428
e. the area of the circle =
22/7 × r^2
= 15.90
