Angle A = x + 22°.
Angle B = x.
And since the angles are complementary:
A + B = 90°
x + 22° + x = 90°
2 x + 22° = 90°
2 x = 90° - 22°
2 x = 68°
x = 68° : 2
x = 34°
Angle A = 56°, angle B = 34°
Answer : The value of x is A ) 34°.
Answer:
0.25 and 25%
Step-by-step explanation:
25% is the same as 1/4
0.25 is the same as 1/4
Answer:
37.5%
Step-by-step explanation:
15 (total number of correct answers)
divided by
40 (total questions)
= 0.375
you now want to mltiply by 100
0.375 x 100
37.5
therefore Bernie has a percentage of 37.5% or when rounded, he has a 38%.
Let x be the width of the cardboard (which means the length of the cardboard is x+88), then the dimensions of the box are:
Length = [(x + 88) - 2(33)]
Width = x - 2(33)
Heighth = 33
Volume = length · width · heighth
144,144 = [(x + 88) - 2(33)] · [x - 2(33)] · 33
144,144 = (x+22)(x-66)(33)
4368 = (x+22)(x-66)
4368 = x² - 44x - 1452
0 = x² - 44x - 5820
use the quadratic formula to calculate that x = 101
Answer: cardboard width = 101, cardboard length = 189
