8 times 14 = 112 + 9 = 121
Answer:
121
Step-by-step explanation:
8 bags of 14 cookies means he bought 112 cookies. Since he already had 9, you add 9 to 112 and get 121 cookies in total.

Can someone help me with this? During a certain period of time about 2000 penguins had an annual growth rate of 19% why will the population of penguins be after 5 years? This is exponential growth and decay
Answer:
Future amount of penguin = 4,772.70
Step-by-step explanation:
Given:
Current amount of penguin = 2,000
Growth rate r = 19% = 0.19
Number of year n = 5
Find:
Future amount of penguin
Computation:
Future amount of penguin = Current amount of penguin[1+r]ⁿ
Future amount of penguin = 2000[1+0.19]⁵
Future amount of penguin = 4,772.70
Find the GCF of the pair of numbers.

Answer:
The gcf would be 1 because 7 is a prime number and the only other number that can go into 7 is 7.
Step-by-step explanation:
the sum of four times a number and another number is 10. The difference of the two numbers is 35. What is the larger number? Also please explain how you got that answer
Answer:
The two numbers are 9 and -26.
The larger number is 9.
Step-by-step explanation:
Let the two unknown numbers be x and y.
The sum of a four times a number x and another number y is 10. Hence:
[tex]4x+y=10[/tex]
And the difference between the two numbers is 35. So:
[tex]x-y=35[/tex]
So, we have the system of equations:
[tex]\left\{ \begin{array} \ 4x+y=10 \\ x-y=35 \end{array}[/tex]
From the second equation, we can add y to both sides:
[tex]x=y+35[/tex]
Now, we can substitute this into the first equation:
[tex]4(y+35)+y=10[/tex]
Distribute:
[tex]4y+140+y=10[/tex]
Simplify:
[tex]5y+140=10[/tex]
Subtract 140 from both sides:
[tex]5y=-130[/tex]
Divide both sides by 5:
[tex]y=-26[/tex]
So, the value of y is -26 .
Then it follows that the value of x is:
[tex]x=y+35[/tex]
Substitute -26 for y:
[tex]x=-26+35=9[/tex]
So, our two numbers are 9 and -26.
The larger number is 9.
So, our answer is 9.

(ANSWER FOR FREE BRAINPOINTS!) (FIRST TO ANSWER GETS BAINLIEST) The local park has a rectangular swimming pool that measures 40 yards in length and 15 yards in width. The community is planning to build a smaller swimming pool that is similar to the current pool. 40 yards, 15 yards, 24 yards. If the length of the new smaller pool will be 24 yards, what will be the width of the smaller pool in yards?
Answer:
9 yards
Step-by-step explanation:
Since both pools are similar, therefore the ratio of their length and width would be equal. That is:
Length of the current swimming pool : length of the new swimming pool = width of the current swimming pool : width of the new swimming pool
Thus, we can set up a proportion as shown below:
Let the width of the new swimming pool be x.
40 : 24 = 15 : x
[tex] \frac{40}{24} = \frac{15}{x} [/tex]
Cross multiply
[tex] 40*x = 15*24 [/tex]
[tex] 40x = 360 [/tex]
Divide both sides by 40
[tex] x = \frac{360}{40} [/tex]
[tex] x = 9 [/tex]
The width of the new swimming that is smaller would be 9 yards.
Complete the steps to solve for x.

solve the system of equations below by graphing both equations with a pencil and paper, what is the solution? y= -x-1 y=x+3
Answer:
(-2, 1)
Step-by-step explanation:
Well, to actually graph it, for the first line you'd have one point at (0, -1) [0 right, 1 down] , then you go down one, right one, and place a point there, down another, right another, and repeat.
For the second you'd place a point on (0, 3) [0 right, 3 up] and then go one up, one right, and place a point. One up, one right and place a point and repeat that. the point where the two lines cross would be your answer. If you don't want to do that then the answer is (-2, 1) I believe.

Answer:
8. p(t) = 5(2^t)
9. 20, 40, 80
10. doubles every year
11. multiplies by 4
12. no, it will soon exceed available habitat
Step-by-step explanation:
8. From the graph, a = p(0) = 5, and b = p(1)/p(0) = 10/5 = 2.
The function is ...
p(t) = 5(2^t)
__
9. You can read the values from the graph: 2 years: 20; 3 years: 40; 4 years: 80.
If you insist on evaluating the function, you have ...
p(2) = 5(2^2) = 5·4 = 20
p(3) = 5(2^3) = 5·8 = 40
p(4) = 5(2^4) = 5·16 = 80
__
10. The population doubles each year.
__
11. In 2 years, the population doubles twice, so is multiplied by 4.
__
12. No. Exponential functions don't last long in the real world. Eventually, required resources run out. In 15 years, there would be 163,840 snakes; in 20 years, there would be 5.2 million snakes; in 40 years, there would be 5.5 trillion snakes, about 44 snakes for every acre of land on earth (including polar areas).
