Answer:
False
Step-by-step explanation:
5x - 2y + 1 > 0
plug in the given ordered pair x= -2 and y = -1:-
5(-2) - 2(-1) + 1
= -10 + 2 + 1
= -7 which is less than 0 therefore the answer is False
Answer:
can you post the question but more clear I didn't understand
Step-by-step explanation:
post it again I didn't understand
Solution:
(a) In the given figure,
BD is the bisector of angle ABC, thus:
So, write as follows:
(i)
Therefore,
(ii)
OB=OA=OD radii of the same circle.
As OB=OA then in triangle AOB,
BOD is a diameter of a circle. then by theorem of circle,
thus,
OA=OD , in the tringle AOD,
In triangle AOD,
Therefore,
(iii) By the theorem of circle, the angle formed at the center of the circle is twice the angle formed at the circumference of the circle with the same base.
Therefore,
(iv)
OA=OD , thus tringle AOD is an isosceles triangle,
Therefore,
Answer:
7.2
Step-by-step explanation:
When rounding, you check the number to its right. If it's 4 or lower, it will stay the same. If it's 5 or higher, you add one to it.
Hope this helps!
The area of a wooden frame is expressed as 252cm²
The formula for calculating the perimeter of a square is expressed as:
P = 4L where
L is the side length of a square
For the outer edge of the wooden frame with a perimeter of 96cm
96 = 4L
L = 96/4
L = 24 cm
Area of the outer wooden frame = 24² = 576cm²
Similarly for the inner edge of the wooden frame with a perimeter of 72cm
72 = 4L
L = 72/4
L = 18 cm
Area of the inner wooden frame = 18² = 324cm²
Area of the wooden frame = Area of the outer frame - Area of the inner frame
Area of the wooden frame = 576 - 324
Area of the wooden frame = 252cm²
Hence the area of a wooden frame is expressed as 252cm²
