Well seeing as how its around the park we think perimeter.
P= 2L +2W
P= 2(150)+ 2(125)
P= 300 + 250
P= 550
so we know the perimeter of the park is 550 yards but she walks this perimeter twice so 550*2 gives you 1100 yards that she walked.<span />
Answer:
47 million dollars
Step-by-step explanation:
A charity received a donation of 17.9 million. If this represents 38% of the charity's donated funds, what is the total amount of its donated funds. Round your answer to the nearest million dollars.
First, let's set the total funds as x.
If 38% of x is 17.9 million dollars, we can write this equation.
38% * x = 17.9 million.
Simplify.
0.38 * x = 17.9 million
Divide both sides by 0.38.
x = 47.105 million
Round to nearest million
x = 47 million dollars
So, the total amount is 47 million
Answer:
a=240
b= 1.16
Step-by-step explanation:
The general form of exponential function for growth is given by:
y = a(1+r)ˣ
We can rewrite it by letting 1+r = b
y= abˣ
a from the given equation represents the initial number of birds, which is given by 240. Hence, a = 240
In (1+r), r is given as the rate of increase, which is given as 16% or 16/100=0.16.
For r = 0.15
b = 1+r
b = 1+ 0.16
b = 1.16
Substituting it in the initial equation:
y = abˣ
y = 240 (1.16)ˣ
where a = 240 and b = 1.16
Answer:
3x+5y=1025
x+y=275
Step-by-step explanation:
We can use system of equations to solve this problem. Let's use x for student tickets and y for adult tickets.
Equation 1
3x+5y=1025
This equation comes from the cost of tickets. Each child ticket costs $3 and each adult ticket costs $5. The total value of tickets sold is $1025.
Equation 2
x+y=275
The total amount of tickets sold was 275.
The number half way between 170,000 and 180,000 is 175,000.
