Answer: 200 hats in total
Steps:
x * .4 = 80
x = 80/.4
x = 200
Check:
200 * .4 = 80
80 = 80 ✅
<span>t in (-oo:+oo)
(3*t)/2+7 = 4*t-3 // - 4*t-3
(3*t)/2-(4*t)+3+7 = 0
(3*t)/2-4*t+3+7 = 0
10-5/2*t = 0 // - 10
-5/2*t = -10 // : -5/2
t = -10/(-5/2)
t = 4
t = 4 is the answer
hope it helps~

The percent error of the measurement, to the nearest tenth of a percent is 18.6%
<h3>Calculating percent error</h3>
The formula for calculating the percent error is expressed as:
%error = actual - measure/actual * 100
Given the following
actual length = 13.4 in
Measured =10.9in
Substitute
%error = 13.4-10.9/13.4 * 100
%error = 2.5/13.4 * 100
%error = 18.65%
Hence the percent error of the measurement, to the nearest tenth of a percent is 18.6%
