Answer:
Based on this screenshot, this is a Test. Do the test no your own, and if you're unsure what the answer is you can come back to it later or just pick random. If you get it correct or incorrect most tests like this will change their difficulty level to see what types of problems you can and cannot answer. This is so your teacher can see what you know about math and what you may need help learning about.
Step-by-step explanation:
(2b^4)^(-1)=1/(2b^4)
^(-1) basically means reciprocal
<h3>Answer: B. 154 square meters</h3>
================================
Work Shown:
C = 44 is the circumference
in general, the circumference of a circle is
C = 2*pi*r
Plug in C = 44 and solve for r.
C = 2*pi*r
44 = 2*pi*r
2*pi*r = 44
r = 44/(2pi)
r = 7.0028175 which is approximate
--------------------
Now plug this into the formula for the area of a circle
A = pi*r^2
A = pi*(7.0028175)^2
A = 154.061985
A = 154 rounding to the nearest whole number
Answer: 1 teashirt=7 L
1 hat= 3L
Step-by-step explanation:
2 T shirts= 31 - 17
2 T shirts= 14
1 T shirt=14/2
1 T = 7 L
14L+ 1H=17 L
one hat = 17 - 14=3 L
