Answer: The scale is 5cm/m (5 cm in the drawing are equivalent to 1 meter on the actual pit)
Step-by-step explanation:
When we have an original measure M, and we redraw it with a new scale, where the new measure is m, the scale used is equal to:
scale = m/M.
In this case, we know that:
The pit is 3m, by 5m
and the drawing to scale is 15cm by 25cm
(15cm is the rescaled version of the 3m side, and 25cm is the rescaled version of the 5m side)
Using the equation above, we can find that the scale is:
Scale = 15cm/3m = 5cm/m
and, if we use the other side, we get:
Scale = 25cm/5m = 5cm/m
Both calculations give the same scale, as expected.
Then the scale is 5cm/m, which means that 5 centimeters in the drawing are equivalent to one meter in the real pit.

Hector bought 6 bottles of juice for $2.40. At that rate, what is the cost of: 1 bottle, 3 bottles, 5 bottles?
Answer:
1 bottle: $0.40
2 bottle: $1.20
5 bottle: $2.00
Step-by-step explanation:
Answer:
Cost of one is 40 cents. Cost of three $1.20. Cost of five $2.00.
Step-by-step explanation:
Divide: 2.40 divided by 6= .4
.4 times 1=.4=.40= 40 cents
.4 times 3=1.2=1.20= $1.20
.4 times 5=2=2.00= $2.00

Step-by-step explanation:
If triangles are similar then they have a scale factor. That is the factor that is being multiplied to each of the sides to create a new set of sides.
We need to find the scale factor between Triangle ABC and Triangle DEF.
We can use Sides AC and DF to determine the scale factor.
It would be 27/9 = 3
So all the sides in triangle DEF are 3 times the length of those in triangle ABC
this means that the side with x cm is just 3 × 5 which is 15 cm.

The volume of a sphere can be found using the formula V = πr . If the sphere has a diameter of 10x y z mm, what is the volume of the sphere in cubic millimeters?
Answer:
500πx³y³z³
Step-by-step explanation:
Volume of a sphere = 4πr³
r is the radius of the sphere
Given
Diameter of the sphere = 10xyz mm
Radius = diameter/2
Radius = 10xyz/2
Radius = 5xyz
Substitute the radius into the formula
Volume of the sphere = 4π(5xyz)³
Volume of the sphere = = 4π(125)x³y³z³
Volume of the sphere = 500πx³y³z³
Hence the volume of the sphere is 500πx³y³z³ mm³

Answer:
B) Vertically stretched by a factor of 3, shifted to the right by 1 unit, and shifted up 2 units.
Step-by-step explanation:
The basic transformations of a rational function as shown here can be modeled by:
[tex]f(x) = \frac{a}{b(x - h)} + k[/tex]
a = vertical stretch / compression.
b = horizontal stretch / compression.
h = horizontal shift.
k = vertical shift.
If there is a negative sign by a, then it is a vertical reflection.
If there is a negative sign by b, then it is a horizontal reflection.
_____________
As seen here, the transformations of
[tex]f(x) = 2 + \frac{3}{x–1} [/tex]
There is no b value because x - 1 is completely factored or it can just be thought of as 1. a or the vertical stretch is a factor of 3 because that is the numerator of the rational expression. There is a horizontal shift of 1 unit to the right because when x is subtracted by 1 in the rational expression, the root of x - 1 by itself is 1 greater than x. Lastly, there is a vertical shift up 2 units because that means all the values of the function will increase by 2 units which moves the whole function up 2.
If you know the area of a circle, how can you find its radius? Use the drop-down menus to explain your answer.
Answer:
down below
Step-by-step explanation:
the area of a circle is pi times radius times radius
in order to find the radius of a circle when you know the area, you need to do the area divided by 3.14. after you have done that, divide that number by 2
please give me brainliest!!
Answer:
Working backward
Step-by-step explanation:
Formula: A = πr²
All you have to do is work backwardly
If you have the area, replace the "A" with the area.
You can replace the π with "3.14"
Then divide the area by "3.14"
Then when you get your answer, divide your answer that you got by its square root --> √
Then when you do that....you get your radius....and from there on, you can check it by substituting.

Find the slope and y-intercept. Pleasee
Answer:
slope: -2
y-intercept: 6
Step-by-step explanation:
Answer:
[tex]slope=-2\\\\y-intercept=6[/tex]
Step-by-step explanation:
The slope is the change in the y-axis over the change in the x-axis. To find the slope, you need to move vertically from a given point. Once you are horizontal to another point, move over to it. Count the spaces between each:
Start at (0,6)Move down to (0,4). Since you moved down two spaces, use the value -2 to define the riseMove to the right to point (1,4). Since you moved to the right 1 space, use the value 1 to define the run.Insert the values into [tex]\frac{rise}{run}[/tex] → [tex]\frac{-2}{1}[/tex]Simplify → [tex]-2[/tex]Therefore, the slope is -2.
The y-intercept is where [tex]x=0[/tex] and where the line crosses over the y-axis. The coordinate point where this happens is [tex](0,6)[/tex], so the y-intercept is 6.

Jan 10, 7:28:48 PM What is the slope of a line parallel to the line whose equation is 3x - 6y = 18. Fully reduce your answer.
Answer:
[tex]1/2[/tex]
Step-by-step explanation:
We are given the line:
[tex]3x-6y=18[/tex]
And we want to find the slope of the line parallel to this given line.
Remember that parallel lines have the same slope. So, if we can determine the slope of the given line, we have the slope of its parallel line.
To determine the slope of the given line, we simply have to isolate the y. So, we can first divide everything by 3. This yields:
[tex]x-2y=6[/tex]
Adding 2y to both sides yields:
[tex]x=6+2y[/tex]
And subtracting 6 from both sides yields:
[tex]x-6=2y[/tex]
Finally, dividing everything by 2 gives us:
[tex]\displaystyle y=\frac{1}{2}x-3[/tex]
Hence, the slope of our line is 1/2.
So, the slope of the line parallel to this line must also be 1/2.

What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Given, The parent function is f(x) = |x|.
Now, The transformed function g(x) = |x + 9| - 5 is shifted x + 9 = 0 ⇒ x = - 9 units along the x-axis and - 5 units along the y-axis.
The vertex of the modulus function is at (- 9, - 5).

Please answer fast, it's important... Q) find the volume of cube whose dimensions are (x+7y), (7x-y) and (xy-5).
Answer:
[tex]Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2[/tex]
Step-by-step explanation:
Given
Shape: Cube
Dimension: (x+7y), (7x-y) and (xy-5).
Required
Determine the volume
The volume is calculated by multiplying the dimensions:
[tex]Volume = (x+7y) * (7x-y) * (xy-5)[/tex]
Evaluate the first 2 brackets
[tex]Volume = [x(7x-y)+7y(7x-y)] * (xy-5)[/tex]
[tex]Volume = [(7x^2-xy)+(49xy-7y^2)] * (xy-5)[/tex]
[tex]Volume = [7x^2-xy+49xy-7y^2] * (xy-5)[/tex]
[tex]Volume = [7x^2+48xy-7y^2] * (xy-5)[/tex]

>) Jamal can run 1 mile in 5.05 minutes.
If Jamal maintains this pace during
a 5-kilometer (5K) race, he expects
to break the course record of
15.25 minutes. Is Jamal's expectation
reasonable? Explain.
Answer:
Yes, his expectation is reasonable
Step-by-step explanation:
Mathematically;
1 mile = 1.609344 km
If he runs this in 5 minutes;
his speed will be 1.609344/5 = 0.3219 km/m
Now he intends breaking the record of 5 kilometers in 15.25 minutes
Distance = speed * time
What we shall have in this case will be;
15.25 * 0.3219 = 4.908
Approximately this is 5 km
So we can conclude that he will break the record if he runs at this speed
