Martina's inground swimming pool is finally finished, and all that's left to do is fill it with water. Martina's family decides to fill their pool using their garden hose to save money, even though they know it will take a really long time. The swimming pool is 10 meters long and 5 meters wide, and Martina's family wants the water to be 2 meters deep. Water from the garden hose flows at a rate of 2,500 liters, or 2.5 cubic meters, per hour.
How long will it take to fill the pool?
Write your answer as a whole number or decimal. Do not round.
hours
Answer:
40 hoursStep-by-step explanation:
Find the required water volume using the volume of prism formula
V = lwhV = 10*5*2 = 100 m³Find the time required
100/2.5 = 40 hoursAnswer:
40 hours
Step-by-step explanation:
The swimming pool can be modeled as a rectangular prism.
Volume of a rectangular prism
[tex]V = lwh[/tex]
where:
l = lengthw = widthh = heightFirst, calculate the volume of water needed:
Given:
l = 10 mw = 5 mh = 2 mSubstitute the given values into the formula and solve for V:
[tex]\implies V=10 \cdot 5 \cdot 2=100\:\: \sf m^3[/tex]
If the water flows as a rate of 2.5 m³/h, divide the volume by the rate to calculate how long it will take to fill the pool:
[tex]\implies \sf Time=\dfrac{Volume}{rate}[/tex]
[tex]\implies \sf Time=\dfrac{100}{2.5}[/tex]
[tex]\implies \sf Time=40\:\:hours[/tex]

The number of items, n, made in 1 hour by a machine is given by n=30/t, t is the time in minutes the machine takes to make one item. The value of r changes for different types of item. On the grid, plot the points that would be used to draw the graph of n = 30/t for values of t from 1 to 4
The equation n = 30/t is an illustration of an inverse variation
The points on the graph are: (1,30), (2,15), (3,10) and (4,7.5)
How to plot the graph?The equation is given as:
n = 30/t
When t = 1, we have:
n = 30/1
n = 30
When t = 2, we have:
n = 30/2
n = 15
When t = 3, we have:
n = 30/3
n = 10
When t = 4, we have:
n = 30/4
n = 7.5
So the points on the graph are:
(1,30), (2,15), (3,10) and (4,7.5)
See attachment for the graph of the equation n = 30/t

A composite figure is formed by combining a square and a triangle. Its total area is 49.5 ft. The area of the
triangle is 33.5 ft. What is the length of each side of the square? Complete the explanation.
The area of the square is
it?, so each side of the square is
ft.
Answer:
The length of each side of square is 5ft.
Step-by-step explanation:
A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.
The area of the triangle is 7.5ft squared.Area of combined figure - area of triangle = area of square.
32.5 ft squared - 7.5 ft squared = 25 ft squared.
So, area of square = 25 ft squared.
Now, by putting the formula for getting the length of each side:
Let the side = a.
Area of square = 25 ft squared
Area of square = a²
Using square root both sides we get:
So, the side = 5 ft.
Therefore, the length of each side of square is 5ft.

What is the equation that represents the function
Answer:
y= 1/5 x -1
Step-by-step explanation:
Find two points ( any two of the three given)
find the slope between 5,0 and 10, 1
( 1-0)/(10-5) = m = slope = 1/5
so the line is of the form y = mx + b :
y = 1/5 x + b sub in any point to calculate 'b'
1 = 1/5 (10) + b
b = -1
y = 1/5 x -1 is your answer
y = 6x - 3 non linear or linear
Answer:
Linear
Step-by-step explanation:
The equation is in the form y = mix + b, which means it is linear.

what is the surface area of this?
Answer:
Surface Area = 96
Step-by-step explanation:
Area of Triangle: Area = 1/2 * Base * Height
Top Triangle:Area = 1/2 * 6 * 2 = 6
Bottom Triangle:Area = 6
Area of Rectange: Area = Length * Height
Left Rectangle:Area = 7 * 3 = 21
Mid RectangleArea = 7 * 6 = 42
Right RectangleArea = 21
Surface Area = TopTri + BotTri + LeftRect + MidRect + RightRect
Surface Area = 6 + 6 + 21 + 42 + 21 = 96

Hi!
The area of the entire figure is 76 units squared.
NOTE: This question has two different shapes: a rectangle, and a triangle.
Rectangle Formula:
Length * Width = Area
[tex]LW=A[/tex]
Triangle Formula
(Base * Height) / 2 = Area
[tex]\cfrac{bh}{2}=A[/tex]
Let's first get the rectangle's area:
[tex]LW=A[/tex]
[tex]8*7=A[/tex]
[tex]56=A[/tex]
The area of the rectangle is 56.
Now, for the top triangle:
[tex]\cfrac{bh}{2} =A[/tex]
[tex]\cfrac{8*2}{2} =A[/tex]
[tex]8=A[/tex]
The area of the top triangle is 8.
Now, for the bottom triangle.
[tex]\cfrac{bh}{2} =A[/tex]
[tex]\cfrac{8*3}{2} =A[/tex]
[tex]12=A[/tex]
The area of the bottom triangle is 12.
Now, add them all together:
[tex]56+8+12=76[/tex]

whats the y intercept and rate of change ill give 20 pt please help me thank u
Answer:
y-intercept= (0,7) and rate of change=
Step-by-step explanation:
The y-intercept of a graph is the point on the graph where it intersects the y-axis or where x=0. In this case it is (0,7) so that is the y-intercept. The rate of change is equal to y2-y1 divided by x2-x1. Basically, just pick 2 random points on the line and subtract their y coordinates, then subtract their x-coordinates and divide the answers with each other. So, one point is (0,7) and another point is (2,4). Therefore, rate of change is 7-4 divided by 0-2. This gives us a rate of change of -3/2

Answer:
a) 1.6×10⁻⁶
b) 2×10⁷
Step-by-step explanation:
You want the product or quotient in standard form of ...
(8×10⁻³)×(2×10⁻⁴)(6×10²)÷(3×10⁻⁵)ExponentsThe rules of exponents apply:
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
Scientific notationA number is said to be in scientific notation if there is one digit to the left of the decimal point, and the multiplier is expressed to an appropriate power of 10. The power of 10 may need to be adjusted so the decimal point is in the correct place. In general, the power of 10 represents the place value of that most-significant digit.
Standard formIn the US, a number is written in standard form as a sequence of digits with an optional decimal point. Integers are written so the least-significant digit has a place-value of 1.
Elsewhere, a number is written in standard form when it is written in scientific notation.
We have given both forms a number here, so you will need to choose the one that is standard form where you are.
a) (8×10⁻³)×(2×10⁻⁴)The product is (8×2)×10^(-3-4) = 16×10^-7 = 1.6×10^-6
= 0.0000016
b) (6×10²)÷(3×10⁻⁵)The quotient is (6/3)×10^(2-(-5)) = 2×10^7
= 20,000,000

Jeremy is x years old. He is 5 years younger than his sister. Together, the sum of their ages is 29 years. Enter an equation that can be used to find Jeremy's age (x).
Answer:
Jeremy is 12 years old
Step-by-step explanation:
Jeremy age=X
Sister age=Y
1. X+Y=29 (sum of their ages)
2. X=Y-5 (he is 5 years younger than his sister)
*Substitute eq 2 into eq 1
Y-5+Y=29
2Y=29+5
2Y=36 (divide both sides by 2)
Y =17
Substitute value of Y into eq 1 to find X
X+17=29
X=29-17
X= 12
Checking answer:
12+17=29
17-5=12
Hence why Jeremy is 12
