The water level in a pool is currently at 1/2 of an inch. Every hour, the water level increases 4.75 inches. How many hours will it take the water level to reach 33.75 inches?
Answer:
7.1 hours
Step-by-step explanation:
Given data
Let the number of hours taken to fill the pool be x
the current quantity is 1/2 the capacity of the pool
we are given that the rate of flow = 4.75 in per hour
let the total amount of water after x hours be y, the expression for the quantity of water is given as
[tex]y= 0.5+4.75x[/tex]
if y= 33.75 in, let us find x
[tex]33.75= 0.5+4.75x\\\\33.75-0.5= 4.75x\\\\33.25= 4.75x\\\\[/tex]
divide both sides by 4.75
[tex]x= 33.75/4.75\\\\x= 7.10[/tex]
Hence, it will take 7.1 hours

Plssss help 20 points and will give BRAINLIEST
Answer:
$550
Step-by-step explanation:
$250 the register so there is already $250
$25 each month
There are 12 months in a year
Multiply
25 * 12 = 300
So $300 each year
Add the amount for register and amount for each month for a year
$250 + $300 = $550

Which sets of ordered pairs show equivalent ratios? Use the grid to help you.
Check ALL that apply.
1.) (1, 2), (2, 3), (4, 7)
2.) (2, 2), (4, 4), (6, 6)
3.) (3, 1), (4, 1), (5, 1)
4.) (4, 1), (8, 2), (12, 3)
5.) (2, 1), (4, 3), (5, 4)
Answer:
2, 4
Step-by-step explanation:
In 2, (2,2) has the same number on both sides, same with (4,4) and (6,6).
Therefore, it is equivalent.
In 4, dividing the first number by the second always results in 4. (4/1=4, 8/2=4, 12/3=4).
Therefore, it works.
The pattern used in 4 is how ratios work. Multiplying/dividing to get one consistent number.

The number in front of the first term of the polynomial
Answer:
Coefficient
Step-by-step explanation:
These numbers are the ones in front of the variables in the beginning of an equation also known as coefficients. The numbers all by themselves without variables are constants. The first term is usually the number with the biggest exponent.

Which characteristics will not prove that quadrilateral PQRS, drawn in a coordinate plane, is a parallelogram?
The answer is letter C. This is because line PQ and RS does not describe a slope. Because PQ and RS are in straight horizontal lines. So it is impossible for PQ and RS to have a slope or a diagonal form.
Answer:
C
Step-by-step explanation:
What is the rate of change in y per unit change in x for this linear function?
A. -5
B. -2.5
C. -2
D. -0.4
B. -2.5
Step-by-step explanation:
This is asking for gradient. Pick any two points (x, y) then calculate the y change ÷ x change. example, (0, -5) and (-2, 0). with [0-(-5) ÷ -2-0] you get -2.5

During training, a hurdler wants to raise the height of the hurdles from the high school standard of 39 inches to the NCAA standard of 42 inches. His best race form last season included a clear over 39-inch hurdle that was modeled by h(t)= -0.025t(t-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (IN FEET)
a) Sketch the graph. Label the axes.
b) If he runs as well as his best race last year, will this hurdler clear the new height? Why or Why not?

Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answer:
x = -4, y = 9
or
(-4, 9)
Step-by-step explanation:
x - 5y = -49
y = -2x + 1
substitute y for -2x + 1
x - 5(-2x + 1) = -49
x + 10x - 5 = - 49
add 5 to both sides
x + 10x - 5 + 5 = - 49 + 5
x + 10x = -44
11x = -44
divide both sides by 11
11x/11 = -44/11
x = -4
substitute x for -4 in any of the original equations
y = -2x + 1
y = -2 * -4 + 1
y = 8 + 1
y = 9
Answer:
x = -4, y = 9 or (-4,9)
