Answer:
it will be -12 F
Step-by-step explanation:
IT is already -2 F so if you add -2 + -10= -12
Answer:
The new amount is 8.
Step-by-step explanation:
80% of 40 is 32, so subtract 32 from 40 to get 8.
First, convert the decimals into improper fractions. The fractions are:
31/10 and 10261/1000. To divide the fractions, change division into multiplication after flipping the numerator and the denominator of the second fraction. This comes out to be 31/10 *(times) 1000/10261.
31*1000 is 31,000 and 10*10261 is 102,610. This equals the fraction: 31,000/102,610. Simplify this.
Answer:

Step-by-step explanation:
The nth term of a geometric progression is
= a₁
where a₁ is the first term and r the common ratio
Given a₅ = 162 and a₈ = 4374 , then
a₁
= 162 → (1)
a₁
= 4374 → (2)
Divide (2) by (1)
= 
r³ = 27
r = ![\sqrt[3]{27}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D)
= 3
Substitute r = 3 into (1) and solve for a₁
a₁
= 162
81a₁ = 162
a₁ = 
= 2
Then
a₂ = a₁ × 3 = 2 × 3 = 6
a₃ = a₂ × 3 = 6 × 3 = 18
The first 3 terms are 2, 6, 18
(ii)
The sum to n terms of a geometric progression is
= 
, then
= 
= 
= 59049 - 1
= 59048
Answer:
4 terms
Step-by-step explanation:
Terms are separated by adding or subtracting.
The terms are:
14m
-8.8n
5p
-1
The variables are not separate terms because they are multiplying with the coefficient, not adding or subtracting.
