Step-by-step explanation:
l = length
w = width
l = w + 2
l×w = area = (w + 2)×w = w² + 2w
l×(w + 4) = area + 88
(w + 2)×(w + 4) = w² + 2w + 88
w² + 6w + 8 = w² + 2w + 88
6w + 8 = 2w + 88
4w = 80
w = 20 cm
l = w + 2 = 20 + 2 = 22 cm
the original length is 22 cm.
the original width is 20 cm.
the original area (22×20) is therefore 440 cm².
the new area (22×24) would be 528 cm².
Answer:
Step-by-step explanation:
This is a normal distribution question with
Mean = 153
Standard Deviation= 10
Since we know that score
a)
P(x > 150.0)=?
The z-score at x = 150.0 is,
This implies that
P(x > 150.0) = P(z > -0.3)
= 1 - P(z < -0.3) = 1 - 0.3820885778110474
P(x > 150) = 0.6179

Step-by-step explanation:
The Roman Numeral, as far as we know, was the only written numbering system used in Ancient Rome andEurope until about 900 AD, when the Arabic Numbering System, which was originated by the Hindu's, came into use.
I have mercy:
8x and 9x+5 (the angles) form a right angle so 8x+9x+5=90 which means x is 5 and plugging it back into the angles 8x we get 40 sinceBHR and angle 8x are vertical angles they are equal to each other and so it's equal to 40
