Answer:
It will take 50 seconds for the pebble to reach the height
Step-by-step explanation:
To calculate the time, simple substitute h(t) for 32,500
So we have
32,500 = 20,000 + 5t^2
5t^2 = 32,500-20,000
5t^2 = 12500
t^2 = 12500/5
t^2 = 2500
t = square root of 2500
t = 50 seconds

A tank that is filled with water drains at a rate of d216+4d−100 d 2 16 + 4 d − 100 gallons per minute where d is the depth of the tank in feet. Pumping out a tank that is 120 feet deep with this same pump would empty the tank at what rate? 1380 gal/min 1380 gal/min 1280 gal/min 1280 gal/min 900 gal/min 900 gal/min 387.5 gal/min 387.5 gal/min 487.5 gal/min
Given:
Consider the tank that is filled with water drains at a rate of [tex]\dfrac{d^2}{16}+4d-100[/tex] gallons per minute where d is the depth of the tank in feet.
Depth of tank = 120 feet.
To find:
The rate of water drain for that tank.
Solution:
We have, rate of water drain in gallons per minute.
[tex]r=\dfrac{d^2}{16}+4d-100[/tex]
where, d is the depth of the tank in feet.
Put d=120, to get the rate of water drain for the tank.
[tex]r=\dfrac{120^2}{16}+4(120)-100[/tex]
[tex]r=\dfrac{14400}{16}+480-100[/tex]
[tex]r=900+380[/tex]
[tex]r=1280[/tex]
Therefore, the rate of water drain is 1280 gal/min. Hence, the correct option is B.

HURRY THIS IS TIMED!! I'LL GIVE BRAINLIEST! Please answer the question attached:
Answer:
Answer A is Linear. You can see this because each term is equal to the previous term plus a fixed amount (3), making it an arithmetic sequence.
Answer B is not linear. This is because each term is a multiple of the previous one, making it a geometric sequence.
Answer:
Function A
Step-by-step explanation:
Each time x increases by 1, y increases by 3. Function B is exponential instead of linear, because y increases by a larger number each time rather than increasing by the same amount.
Good luck :)

write an equation of a line parallel to x=3
Answer: y = 4
Step-by-step explanation:
The equation y = 3 represents a vertical line. Thus, any equation in which y = m = 0 would be parallel to this line. Pick a random b-value and plug it into the equation with a slope of 0 and you should have a parallel line equation.

Emmy goes through a 50-ounce jug of laundry detergent in 40 loads. At the store, she
bought a jumbo jug of detergent. The jumbo jug contains 150 ounces of detergent.
How many loads of laundry can Emmy do with the jumbo jug of laundry detergent?
Hence 120 loads of laundry is required with jumbo jug of laundry detergent.
What is laundry detergent?A sort of detergent (cleaning agent) used to clean soiled laundry is laundry detergent (clothes). There are two types of laundry detergent produced: powder (washing powder) and liquid. Builders (about 50% by weight), surfactants (15%), bleach (7%), enzymes (2%), soil deposition inhibitors, foam regulators, corrosion inhibitors, optical brighteners, color transfer inhibitors, perfumes, dyes, fillers, and formulation aids may all be present in laundry detergents.
∵ Number of jumbo jug = 150 /50
n = 3
∴ Laundry loads required of detergent:
= 40 * n
= 40 * 3
= 120 loads

A car that travels 20 miles in LaTeX: \frac{1}{2}1 2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in LaTeX: \frac{3}{4}3 4 hour at a constant speed. Both cars go miles in LaTeX: \frac{1}{4}1 4of an hour (or 15 minutes). Both cars will travel miles in 1 hour.
Answer:
10 miles per 1/4 hour
40 miles per hour
Step-by-step explanation:
Given that:
A car travels 20 miles in 1/2 hour
Miles traveled per hour :
(20 * 2) / 1 = 40 miles per hour
Mile traveled in 1/4 hour :
Distance = speed * time
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
Car traveling 30 miles in 3/4 hours
(30 * 4) /3 = 120 / 3 = 40 miles per hour
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

What is the sum of all integers $n$ that satisfy
$$-3n < 7n-20 < 3n~?$$
$($In other words, what is the sum of all integers $n$ that satisfy both of the inequalities
$$-3n<7n-20\text{~~and~~}7n-20<3n~?)$$
If you can't figure out the latex here is a screenshot ( in the comments)
Looks like the inequality is
-3n < 7n - 20 < 3n
Add 3n to each side:
0 < 10n - 20 < 6n
Solve the right inequality.
10n - 20 < 6n
Add -10n to both sides:
-20 < -4n
Divides both sides by -4:
5 > n
Now solve the left inequality, and take the intersection of the two solution intervals.
0 < 10n - 20
Add 20 to both sides:
20 < 10n
Divide both sides by 10:
2 < n
So 2 < n < 5. There are only 2 integers in this range (3 and 4), whose sum is 7.
Answer:
7
Step-by-step explanation:
We solve each of the two inequalities separately. To solve the first inequality, -3n<7n-20, we add 3n to both sides:
0<10n-20, then we add 20 to both sides to get
20<10n. Finally, dividing both sides by 10 gives 2<n, so n must be greater than 2.
For the second inequality, 7n-20<3n, we subtract 3n from both sides:
4n-20<0, then add 20 to both sides to get
4n<20. Finally, dividing both sides by 4 gives n<5, so n must be less than 5.
The only integers that are greater than 2 and less than 5 are 3 and 4. So, the sum of all possible integer values of n is 3+4=7.
Does anyone know the answer to this ? I need help!
