Answer:
Step-by-step explanation:
{55x + 2y = 23
{113x + 3y = 51
−55⁄113[113x + 3y = 51]
{55x + 2y = 23
{−55x - 1 52⁄113y = −24 93⁄113 >> New Equation
_____________________
61⁄113y = −1 93⁄113
______ ________
61⁄113 61⁄113
[Plug this back into both equations above to get the x-coordinate of 33⁄61];

The answer is
Letter D -
939.80.
You can refer to the attachment for the rate. Since he is forty-seven years old, use that age to find his rate under a twenty-year endowment insurance. In this case, the rate is 46.99. Multiply that rate to 20 since he purchased a 20-year endowment insurance with a face value of $20,000. (20,000/1,000 = 20)
46.99 x 20 = 939.80
A= π r2 and v=3.14d
---Volume(v=3.14d):
3.14(15) equals 47.1
47.1 rounds to 47
nearest hundreth would be 0 that rounds to .1 or .10,which rounds to 47
v=47
---Area(π r2)
3.14(7.5)^2 is 3.14(56.25)
176.625
176.625 rounded to the nearest hundreth is 176.630.
Answer:
The area of a circle with the diameter of 15 is 176.630.
Answer:Perimeter is the measurement all around the shape. So, to do this we wolud need to add this measurments together
Step-by-step explanation:
8.2+3.9=12.1
12.1+4.5=16.6
Answer:16.6cm
The actual perimeter of the park is 251 meters. You would need to move the decimal 3 spaces to the right in order to get your answer. OR you can just multiply .251 times 1,000 to get your answer.
