Answer:
P = 13.8 yd
Step-by-step explanation:
The perimeter of a rectangle is given by
P = 2(l+w)
=2(4.3+2.6)
= 2(6.9)
=13.8
P = 13.8 yd
Answer:

Step-by-step explanation:
The standard form for an exponential equation is

We have 2 unknowns, a and b, but that's all good because we have 2 (x, y) coordinates we can utilize in order to find a and b. In our coordinate pair, x is the number of years gone by and y is the value after that number of years. The problem tells us that an item was purchased for $500. That translates to "before any time has gone by, the initial value of the item is $500". In other words, with x being time, no time has gone by, so x = 0. When x = 0, y = 500. (0, 500). Do the same for the next set of numbers. When x = 2 years gone by, the value is $551.25, so the coordinate is (2, 551.25). Now we use them to find a. Use the first coordinate:

Anything raised to the 0 power = 1, therefore:
and a = 500.
Now onto the next coordinate point using the a value we just found:

Divide both sides by 500 to get

so b = 1.05.
Now we have the values for a and b, so we fill in:

The sign should be flipped to show that the hours of community service are greater than, or equal to 10 hours.
A composite number is a number that's not prime. A prime number is a number who only has 2 factors (1 and itself). A composite number has multiple factors.
For example;
7 is prime, as the factors of 7 are only 1&7.
14 is composite, as there are 4 factors (more than 2); 1&14, 2&7.
91 is composite, as it has the following factor pairs; 1&91, 7&13.
139 only has 1&19, making it prime.
13 only has 1&13, making it prime.
29 only has 1&13, making it prime.
Your answer is A.) 91.
I hope this helps!
