Mathematics

OLga [1]3 years ago
5 0

Answer:

A

Step-by-step explanation:

The general form of compound growth formula is:

F=P(1+r)^t

Where

F is the future amount

P is the initial amount

r is the rate of growth in decimal

t is the time in years

In the problem, initially there is 825 quail, so

P = 825

The future amount is given as "Y", so we will replace "F" of formula by "Y"

The rate of growth in 13%. This converted to decimal is:

13/100 = 0.13

The time is 3 years, so t = 3

Now, we substitute and find the model equation:

F=P(1+r)^t\\Y=825(1+0.13)^3\\Y=825(1.13)^3

Correct answer choice is A

–3.4 + (–8 + 2) = [ ? + (–8)] + 2<br><br> whats the missing number
Ilia_Sergeevich [38]
I suppose what makes this question annoying is that there is the question mark so what i'll do first is substitute the question mark with x. also, there are annoying parenthesis so we'll first eliminate the ones we don't need. now we just have to solve for x. -3.4 + (-8 + 2) = (x + (-8)) + 2 adding a negative number is subtracting that number so x + (-8) = x - 8 -3.4 + 2 - 8 = x - 8 + 2 -3.4 -6 = x - 6 x = -3.4 make sure you are aware that the negative sign belongs to the number after it so -2 + 4 is not -(2+4) = -6 but rather 4 - 2 = 2. let me know if you have any questions!

Solve - pv + 40 &lt; 65 for v<br> solve 7w - 3r = 15 for r
Katarina [22]

Answer:

v > -25/p

r = -5 +7/3 w

Step-by-step explanation:

- pv + 40 < 65

Subtract 40 from each side

- pv + 40-40 < 65-40

-pv < 25

Divide each side by -p  (remember to flip the inequality since we are dividing by a negative)

-pv/-p > 25/-p

v > -25/p


7w - 3r = 15

Subtract 7w from each side

7w-7w - 3r = 15-7w

-3r = 15-7w

Divide by -3

-3r/-3 = (15-7w)/-3

r = -5 +7/3 w

two friends have a conversation mario tells roberto "the money i have is twice that you have" roberto answer "if you give me 6 d
crimeas [40]

Answer:

Before anyone gives anyone money, Mario has 24 dollars and Roberto has 12 dollars. After they give each other money, both of them have 18 dollars.

Step-by-step explanation:

Mario has twice as much as Roberto, BUT if Mario gives Roberto 6 dollars, then they have the same amount.

M = 2R

M - 6 = R + 6

To isolate M, you need to add 6 on both sides.

M - 6 + 6 = R + 6 + 6

M = R + 12

M = 2R

Substitute M for the value above that we found.

R + 12 = 2R

Now we subtract R on both sides, so that only one side has the variable R.

R - R + 12 = 2R - R

12 = R

M = 2R

Substitute for the value of R.

M = 2 x 12

M = 24

if you start on the unit circle at (0,-1) and move 360° in the counterclockwise direction, at what angle measure on the unit cir
maks197457 [2]

Answer:

270°

Step-by-step explanation:

(0, -1) is at the 270° angle.  If you do a 360°, you end up back where you started, so the angle is still 270°.
