Answer:
2 hours and 45 minutes
Step-by-step explanation:
Answer:

Explanation:
<u>Equation:</u>

This is a decaying exponential function, because the exponent is negative.
Then, the larger the value of t (number of months), the smaller A (the number of hectares).
The factor 1,562.5 is the initial number of hecares, when t = 0.
You must find the value of t when A equals 500, thus solve the equation:

Divide both sides by 1,562.5


Take base-10 logarithms on both sides:


Note that the logarithm of a number decimal number is negative number, thus t will be positive. When you compute that, it is about 4.9 months.
Xy= 540
y= 5x/3
x(5x/3)=540
5x^2/3=540
1630=5x^2
x=sqrt(1620/5) = sqrt(324)= 18
x= 18yd
y=30yd
answer: 18 x 30 yards
Answer:
$5,040
Step-by-step explanation:
First you multiply 40 times 7. Then turn it to a percent, .280. Finally multiply it by 18,000 and get 5,040.
Answer:
The area of the triangle is 10 square units.
Step-by-step explanation:
The formula for area of a triangle is A =
bh.
The problem gives us this information:
b = 4 units
h = 5 units
You can use the formula and plug the numbers into the equation to find your answer of 10 square units.
