Answer:

2 2/3 cups of sugar

Step-by-step explanation:

If your ratio is 3 flour to 4 sugar, and you use 2 cups of flour, set up your proportion as follows:

$\frac{3}{4}=\frac{2}{x}$

Cross multiply to get 3x = 8 and x = 8/3 which is 2 and 2/3 cups of sugar.

Jenna and her 2 sisters want to take a camping trip. they have $125 saved. each of them will save $24 a week until they have $42

Alexxandr [17]

Answer:

After 4 weeks they have $413

After 5 weeks they have $485 (more than enough money)

Step-by-step explanation:

we know that here are 3 people saving up this money and we know that they have already saved 125 dollars.

if each saves $24 per week... 24*3=72 (total profit per week)

for 4 weeks... 72*4=288

288+125(already saved up)= 413

If they go one more week and save up another 72 dollars in 1 week this will bring them past their goal

There are 30 boys in a sporting club. 20 of them play hockey and 15 play volleyball. Each boys plays at least one of the two gam

SVETLANKA909090 [29]

Answer:

5 boys play all the two games

25 boys play only one game

Step-by-step explanation:

Sets

There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).

All the boys play at least one of the two games, so no elements are outside both sets.

There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.

Thus 20 + 15 - 30 = 5 boys play both games

Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.

Thus 15 + 10 = 25 boys play only one game.

Is my answer correct?

ziro4ka [17]

Here is the answer to the given problem above.
Here is the exponential function to model this situation:
f(x) = 420(0.79)x
Now, solve with the given values.
P(t)=420×(.79)^t P(5)=420×(.79)^5=129
So the answer would be 129 animals.
Hope this answer helps. Thanks for posting your question!

For the given function, find the vertical and horizontal asymptote(s) (if there are any). f(x) = the quantity x squared plus thr

vodka [1.7K]

The vertical asymptotes are: "x = 3" and "x = -3" .
__________________________________________
The horizontal asymptote is: "y = 2" .
___________________________________________
Explanation:
___________________________________________

f(x) = $\frac{x^{2}+ 3}{ x^{2} - 9}$ ;

We know that "(x² − 9) ≠ 0 ; since we cannot divide by "0" ; so the "denominator" in the fraction cannot be "0" ;

since: 9 − 9 = 0 ; "x² " cannot equal 9.

So, what values for "x" exist when "x = 9" ?

x² = 9 ;

Take the square root of EACH SIDE of the equation ; to isolate "x" on one side of the equation ; and to solve for "x" ;

√(x²) = √9 ;

x = ± 3
__________________________________________
So; the vertical asymptotes are: "x = 3" and "x = -3" .
__________________________________________
The horizontal asymptote is: "y = 2" .
__________________________________________
(since: We have: f(x) = $\frac{x^{2}+ 3}{ x^{2} - 9}$ ;

The "x² / x² " as the highest degree polymonials; both with "implied" coefficients of "1" ; and both raised to the same exponential power of "2".
