Answer:
440m^2
Step-by-step explanation:
15400/(22/7)=4900, which is r^2, so r=70. Now we can find the circumference by doing 22/7*2*70, which is 440.
Answer:
All positive rational numbers greater than 50
Step-by-step explanation:
Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation
y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58
Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
Answer:
1,184 sq cm
Step-by-step explanation:
Surface area= 2 (1/2 x 8 x 12 + 34 x 10) + 34 x 12
= 1,184 sq cm
Hope this helps!
Answer:
1 ) 0.023
2 ) 0.1004
Step-by-step explanation:
2 / 100 + 3 / 1000
= 0.02 + 0.003
= 0.020 + 0.003
= 0.023
1 / 10 + 4 / 10,000
= 0.1 + 0.0004
= 0.1000 + 0.0004
= 0.1004
The formula for figuring the monthly payments on such a loan is
... A = P(r/12)/(1 -(1 +r/12)^(-12t))
where r is the annual interest rate (.065), P is the principal amount (we want to find), t is the number of years (30), and A is the monthly payment.
Filling in the given values, we have
... 821.69 = P(.065/12)/(1 - (1 +.065/12)^(-12*30)) = 0.00632068·P
Then the principal amount is
... P = 821.69/0.00632068 = 130,000.25
The most appropriate choice is ...
... 4. $130,000
