Answer:
y=3
Step-by-step explanation:
10y-50=-20
first add 50 to both side
10y=30
then divide 10 in the both side
y=30/10
so the answer is y=3
The height should equal to 8m
Answer:
Step-by-step explanation:
First convert the transmit power into μW, considering 1 W = 1000000 μW:
- 0.35 W = 0.35*1000000 μW = 350000 μW
Find how many factors of 10 the power dropped:
Find the distance:
Answer:
Volume = 125
Surface area = 150
Step-by-step explanation:
Volume = 5 x 5 x 5 = 125
Surface area = 6 x 5 x 5 = 150

Answer: his pay for the 4th year is $1453.16
Step-by-step explanation:
The landlord raises the rent 1.25% each year. It means that the rent is increasing in geometric progression.
The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = $1,400
r = 1 + 1.25/100 = 1.0125
n = 4 years
The 4th term(year), T4 is
T4 = 1400 × 1.0125^(4 - 1)
T4 = 1400 × 1.0125^3
T4 = $1453.16
