Answer:
454cm
Step-by-step explanation:
perimeter of rectangle = 2(l+b)=2(1.52+0.75)=4.54meter =4.54*100 cm( 1m =100cm) = 454cm.
Answer:
Replace the radius into the equation and compute the area
Step-by-step explanation:
The area of a circle is computed as follows:
area of a circle = π*r²
where <em>r</em> is the radius of the circle.
I cannot understand which radius has the circle. In the case that r = 3 yards, the area is:
area of a circle = π*(3)² = 28.3 yd²
And in the case that r = 5 yards, the area is:
area of a circle = π*5² = 78.5 yd²
Answer: y > 4.5 or y < -4.5
You use the rule
if |y| > k, then y > k or y < -k
where k is some positive number. In this case, k = 4.5
Answer:
( - , - )
Step-by-step explanation:
Given the 2 equations
8x = 2y + 5 → (1)
3x = y + 7 → (2)
Rearrange (2) expressing y in terms of x by subtracting 7 from both sides.
y = 3x - 7 → (3)
Substitute y = 3x - 7 into (1)
8x = 2(3x - 7) + 5 ← distribute and simplify right side
8x = 6x - 14 + 5
8x = 6x - 9 ( subtract 6x from both sides )
2x = - 9 ( divide both sides by 2 )
x = -
Substitute this value into (3) for corresponding value of y
y = 3 × - - 7 = - - = -
Solution is (- , - )
Angle 1 and 2=105°
75+Angle 2=180°
180-75=105=Angle 2
Angle 2=Angle 1
