The perimeter is just adding all the sides together.

a.) 180 = 40 + 40 + x + x

180 = 80 + 2x Subtract 80 on both sides

100 = 2x Take 1/2 of 100 to get x

x= 50cm


b.) 1000 = 150 + 150 + x + x

1000 = 300 + 2x Subtract 300 on both sides

700 = 2x Take 1/2 of 700 to get x

x = 350

How many tickets were sold after June 15th?
AysviL [449]

Answer: About 45.

Step-by-step explanation: There's always a pattern in these kinds of questions, you can see for 9th to 13th August, the number has always been  between 20 to 40. And since on 13th August the graph is on a rise again, it would be around 45. 90 is just not realistic considering there's only an increase of around 5-10 tickets every day.

PLS HELP RN <br> $4000 student loan. 10% compound interest annually. Total loan amount by 4 years?
ddd [48]

Answer:

$2,400

Step-by-step explanation:

We get 10% of 4,000 by dividing 4,000 by 10.

4,000 ÷ 10 = 400

To get the amount that 4,000 is subtracted by we multiply 400 by 4.

400 × 4 = 1,600

To get the answer we subtract 4,000 by 1,600.

4,000 - 1,600 = 2,400

Hope I helped!
