Answer:
Absolute error = 13-12.7=0.3
13 =100%
12.7=x
x=(12.7)(100)/13
x=97.7
the percentage error is 97.7%
The values of x and y are 15 and 75, respectively
<h3>How to determine the values of x and y?</h3>
The statements are given as:
- Angle x and angle y are complementary angles
- Angle y is 5 times the size of angle x
These mean that
x + y = 90
y = 5x
Substitute y = 5x in x + y = 90
x + 5x = 90
Evaluate the sum
6x = 90
Divide by 6
x = 15
Substitute x = 15 in y = 5x
y = 5 *15
Evaluate
y = 75
Hence, the values of x and y are 15 and 75, respectively

Answer:
a=10.35
Step-by-step explanation:
Hey There!
All you have to do is plug in the L and W value
a= 4.5(2.3)
4.5x2.3=10.35
so a=10.35
<span> y = 2/7 x - 1/7
slope = 2/7
</span><span>perpendicular lines, slope is opposite and reciprocal
</span>so slope of new line = -7/2
<span>passes through the point (9,-32)
</span><span>slope-intercept form: y = mx + b
so
b = y - mx
b = -32 - (-7/2)(9)
b = -32 + 63/2
b = -1/2
equation in </span>slope-intercept form:
y = -7/2 x - 1/2
