The first term is -43.
Explanation:
an = a + (n - 1)d
a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation
Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5
Subtitute d into the first equation
a + 99 = 56
a = -43
a refers to the first term, hence the first term is -43.
60% of
35 is 21
Change the percentage (60) into a decimal by dividing it over 100:
Divide 21 by the decimal:

Answer:
π(6 cm) (10 cm)
Step-by-step explanation:
As we know that
The formula to calculate the lateral surface area of the cone is πrl
where
r denotes the radius i.e. 6 cm
l denotes the length i.e. 10 cm
So based on the above information
The expression that shows the lateral surface area of the cone is
π(6 cm) (10 cm)
Therefore the third option is correct
Hence, the same would be relevant
Answer:
The answer is 2:10
Step-by-step explanation:
60 mins in an hour. 1:45+25 is 1:70, turn that into ours and you get 2:10.
Answer:
p = 17.5
Step-by-step explanation:
This is the answer because:
1) First, we have to isolate x
2) To isolate x, first -6 from +6 and 48
+6 - 6 = 0
48 - 6 = 42
Equation: 2.4p = 42
3) Now we are left with 2.4p = 42
4) Next, divide 2.4 from 2.4 and 42
2.4/2.4 = 0
42/2.4 = 17.5
5) We are left with
p = 17.5
Therefore, the answer is p = 17.5
Hope this helps!
