Rate is the number of death over time. So 1000 divide by 365 days =2.78

Answer:

14.29%

Step-by-step explanation:

The death rate for that year will be the year percent decrease in the population of fish.

Initial population of fish = 7000fishes

Death of fish for the year = 1000fishes

death rate for the year = amount of death of fish for that year/initial population of fish × 100%

Yearly death rate = 1000/7000×100%

= 14.29%

Write answer in slope intercept form (3,-8); slope= -3

Slav-nsk [51]

Answer:

$y=-3x-8$

Step-by-step explanation:

The slope intercept form is $y=mx+b$ .

The " $mx$ " is the slope; which in this case is -3. So $-3x$ .

The " $b$ " is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.

This is why the answer is $y=-3x-8$ .

Karo-lina-s [1.5K]

Answer: 700 miles.

Step-by-step explanation:

1. You know that 23% of the total distance of the flight from Albuquerque New Mexico to Austin Texas is 161 miles.

2. Then, keeping that information on mind, you can calculate the total distance of the flight (which you call $x$ ) as following:

$\frac{161miles}{23\%}=\frac{x}{100\%}$

Solve for $x$ . Then, you obtain that the result is:

$x=\frac{161miles*100\%}{23\%}\\x=700miles$

A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time i

Likurg_2 [28]

R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44
