for perimeter you need to add, 15ft, 80ft, 30ft, 50ft, and 60ft which is 235 feet
for area you need to multiply 15ft times 80ft to get the area of the long verticle one which is 1200
then multiply 50ft times 30ft which is 1500
then add 1200 and 1500 which is 2700ft^2
Answer:
The answer is −2x+y=−4 or 2x−y=4 . Standard form is Ax+Ay=C
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Answer:
3.81 inches
Step-by-step explanation:
πr² + 100 = π(r+3)²
divide by π and simplify:
r² + (100/π) = r² + 6r + 9
100/π = r² + 6r + 9
31.8309886184 - 9 = r² +6r
r² = 6r - 22.8309886184
0 = 6r - 22.8309886184
22.8309886184 = 6r
divide by 6:
3.80516476973 ≈ 3.81 inches
Answer:
Step-by-step explanation:
Given that during the first 13 weeks of the television season, the Saturday evening 8:00 P.M. to 9:00 P.M. audience proportions were recorded as ABC 29%, CBS 28%, NBC 25%, and independents 18%
H0: Proportion did not change
Ha: Proportions changed
5% significance level is used
ABC CBS NBC INDEP TOTAL
percent 29 28 25 18 100

Since p > alpha, we accept null hypothesis
The observed values are as per the proportions.
Answer:
It's 2 4 7
Step-by-step explanation:
The first column says "one number is correct and well placed," so it's number two, because the third column says "One number is correct but incorrectly placed," which means number 2 is in the same place, and number 4 is in the last, but the fourth column says "Two numbers are correct but incorrectly placed," means 4 and 7 are in the first and second columns, but supposed to be in the 2nd and 3rd place, respectively. As a result, it's 2, 4, 7, and I hope you understand because I'm terrible at explaining things.
