Answer:
$20.44
Step-by-step explanation:
first solve for the whole thing
10 x 6 = 60
now to the red part
2 x 1.5 = 3
now the blue
r^2 * pi = a
2^2 * 3.14
4 * 3.14 = 12.56
now add red and blue
3 + 12.56 = 15.56
now subtract that sum from the whole
60 - 15.56 = 44.44
now do
44.44 / 10 = 4.444
now see how much it would cost for the grass
4.444 * 4.60 = 20.4424 ≈ 20.44
it would cost $20.44 to get the grass reseeded
Answer:
$20.44

Use your answer from Question #5 and the coordinates of P to find the coordinates of P’. Explain your work, including how the scale factor was used to determine the answer.
Answer:
Scale factor is used to find the coordinates depending upon whether the scale factor value is less than one or more than one.
Step-by-step explanation:
A scale factor is a number which scales, or increases, some amount. In the condition y = Cx, C is the scale factor for x. C is likewise the coefficient of x, and might be known as the steady of proportionality of y to x.
An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1. To discover the expanded picture, we initially should know the directions of our unique picture. At that point we basically increase the arrange by the scale factor to discover the widened picture.

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms and means slope m and x-intercept (instead of y-intercept) a.
Hope this helped :D

The figure is made up of hemisphere and a cylinder.
what is the exact volume of the figure?
box [] cm^3
Answer:
Data: (Cylinder)
h (height) = 8 cm
r (radius) = 5 cm
Adopting:
V (volume) = ?
Solving:(Cylinder volume)
Note: Now, let's find the volume of a hemisphere.
Data: (hemisphere volume)
V (volume) = ?
r (radius) = 5 cm
Adopting:
If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere
Formula: (Volume of the hemisphere)
Solving:
Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)
Volume of the figure = cylinder volume + hemisphere volume
Volume of the figure = 628 cm³ + 261.6 cm³

Answer:
1.) Mean= 136
Median=133
2.) Mean=136
Median=133
Answer: Landers
Mean = 136
Median = 133
Skakalski
Mean = 130
Median = 133
Step-by-step explanation: to find the mean add all the numbers then divide it by how many numbers there are.
To find the median write all the numbers from smallest to largest then cancel the number at the end until you reach the “middle” number.

Step-by-step explanation:
a 4000 pound car driving at 40 miles/hour has how many times the kinetic energy of another 4000 pound car driving at 10 miles/hour.
The comparison of the kinetic energy of the given bodies is required.
The first car has 16 times more the kinetic energy of the second car.
Kinetic energym = Mass of car = 4000 pound
[tex]v_1[/tex] = Initial velocity of car = 40 miles/hour
[tex]v_2[/tex] = Final velocity of car = 10 miles/hour
The mass of the car is constant so we have the relation
[tex]K\propto v^2[/tex]
Thus,
[tex]\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow K_1=K_2\dfrac{40^2}{10^2}\\\Rightarrow K_1=16K_2[/tex]
