Answer:
a) 63°
b) 127°
Step-by-step explanation:
Complements are 90° while supplements are 180°.
So you need to find the complement of 27°. So, 90-27=63
To find the supplement, it is 180-53=127
Answer:
the amount borrowed is ≅ $527
Step-by-step explanation:
Given that;
simple interest rate r = 180% p.a
Let the amount borrowed (principal) be $x.
time t = 4 weeks = 28 days
= 28/365 year
= 0.0767 year
we all know that :
![Simple \ \ interest = \dfrac{P*r*t}{100}](https://tex.z-dn.net/?f=Simple%20%5C%20%5C%20%20interest%20%3D%20%5Cdfrac%7BP%2Ar%2At%7D%7B100%7D)
![Simple \ \ interest = \dfrac{x*180*0.0767}{100}](https://tex.z-dn.net/?f=Simple%20%5C%20%5C%20%20interest%20%3D%20%5Cdfrac%7Bx%2A180%2A0.0767%7D%7B100%7D)
Simple interest = 0.13806x
Total amount to be paid after 4 weeks= Interest+Principal
= x + 0.13806x
= 1.13806x
Thus;
1.13806x = $600
x = $600/ 1.13806
x = $527.21
Hence; the amount borrowed is ≅ $527
Step-by-step explanation:
x-intercept= -4
yintercept= -7
Answer:
80 : 100: 40: 140
Step-by-step explanation:
The four angles of a quadrilateral add to 360 degrees.
Ratio
4 : 5 : 2: 7
Multiply each by x
4x: 5x : 2x : 7x This total is 360 degrees
4x+5x + 2x+7x =360
18x = 360
Divide each side by 18
18x/18 = 360/18
x =20
The angles are
4x: 5x : 2x : 7x
4(20): 5(20) : 2(20) : 7(20)
80 : 100: 40: 140
Volume = area of base * height = 12 1/6 * 2 3/4 = 73/6 * 11/4 = 803/24
= 33 11/24 cubic feet
