Anature museum has 2008 specimens of early birds, some with 222 wings and some with 444 wings. the specimens have a total of 40384 wings. how many specimens are there with each number of wings?

Let's assume

number of birds with 2 wings is x

number of birds with 4 wings is y

A nature museum has 2008 specimens of early birds

so,

Total of wings of 2 wings bird =2x

Total of wings of 4 wings bird =4y

The specimens have a total of 4384 wings

so, we get

we can divide both sides by 2

so, we get system of equations as

we can solve for x and y

We can subtract both equations

so,

number of birds with 2 wings is 1824

number of birds with 4 wings is 184.............Answer

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
