Answer:
Number = 92
Step-by-step explanation:
Let the unit digit is x and that of tens digit is y.
ATQ,
x+y = 11 ....(1)
The unit's digit is 7 less than the ten's digit
x = y-7 ...(2)
Put the value of x from equation (2) in (1)
y-7+y = 11
2x-7 = 11
2x = 11+7
2x = 18
x = 9
Put the value of x in equation (1)
9+y = 11
y = 2
Hence, the number is 92.
777.75
after 2 years. Because 4.25 is equal to .0425 then times that by the number.
The amount invested at 5% is $12,000 whereas the remaining $15,000 was invested at 4%
What is the amount of annual return for each investment?
The amount of annual return for each investment is determined as the amount invested multiplied by the rate of return
Let us assume that y was invested at 5% and the 27000-y, the remainder was invested at 4%
Total annual return=(y*5%)+(27000-y)*4%
Total annual return=0.05y+1080-0.04y
total annual return=0.01y+1080
total annual return=1220
1220=0.01y+1080
1200-1080=0.01y
120=0.01y
y=120/0.01
y=$12,000(invested at 5%)
amount invested at 4%=27000-12000
amount invested at 4%=$15,000

Answer:
230
Step-by-step explanation:
V = Base x hight
2070 = Base x 9
Base = 2070/9
Base = 230
Area = base
Area = 230
