Answer:
80.6
Step-by-step explanation:
F = 9/5 C + 32
F = (9/5)*27 + 32 Substitute 27 into the equation
F = 243 / 5 + 32 Multiply 9 and 27 together
F = 48.6 + 32 Divide by 5
F = 80.6 Add on 32
A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.
2*27 = 54 Add 30
54 + 30 = 84
This quick way will tell you if you get near the right answer.
223
-119
104
In stead of doing 3-9 and 2-1 do 23-19 then 2-1

Answer:
The countertop is 8.37 square meters
Step-by-step explanation:
Let
L ----> the length of the countertop
W ----> the width of the countertop
we know that
The area of rectangle (countertop) is equal to
we have
Remember that
To convert feet to meters multiply by 0.305
so
Find the area in square meters
This is an arithmetic series,
so
S(n) = (n/2)*(a(1)+a(n))
S(25) = (25/2)*(a(1)+a(25))
n=25
a(n) = 3n-2
a(1)= 3*1-2=1
a(1)=1
a(25) = 3*25-2=75-2=73
a(25)=73
S(25) = (25/2)*(1+73)=(25/2)*74=925
S(25)=925
Answer : 925
