Answer:
t = 8 days i saw it on a website if i recall its the answer
Step-by-step explanation:
speed = distance/time
4 P = 1 House / 10 Days
P = 1 House / 40 Days
Let T = Time it takes for five painters.
5 P = 1 House / T
5(1/40) = 1 /T
1/8 = 1 /T
T = 8 Days

Please Help me ( i give brainly) Given the graphs of the three functions below...At what x value are all functions equal to each other?
x = 0
x = 10
x = 7
x = 4
Answer:
7
Step-by-step explanation:
Because it is asking what X value are all the functions equal to just find a point that lies on X that they all come to.
In this case it's 7
Answer:
x = 7
Step-by-step explanation:
The functions are equal to each other where the lines of the functions intersect each other.
The intersection point is (7, 3).
The x-value at this point is 7.
Hence, x = 7.

of semi circle
circumference of semi circle = [tex]\pi[/tex]d
[tex]\pi[/tex]x10 = 10[tex]\pi[/tex]
semi circle so divide by 2 = 5[tex]\pi[/tex]

46.2 + 15.7 = 61.9
The potential energy of an object varies jointly with the mass of the object and the height of the object off the ground. a 40-kg object is 2 meters off the ground. the potential energy of the object is 784 joules. a 10-kg object is 3 meters off the ground. what is the potential energy of the 10-kg object? 33 joules 131 joules 294 joules 1,176 joules
The potential energy of the 10-kg object is 294 joules.
What is Variation?Variation is a mathematical term that shows the relationship between two or more parameters or quantities in an equation.
Analysis:
let potential energy be = P
let mass be = m
let height be = h
P ∝ mh
P = kmh
when P = 784, m = 40kg, h = 2 meters
784 = k x 40 x 2
k = 9.8
P = 9.8mh
when m = 10kg, h = 3 meters
P = 9.8 x 10 x 3 = 294 joules.
In conclusion, the potential energy of the object at 3 meter height is 294 joules.

a right cylinder has a height of 22 1/4ft and a diameter 2 2/5 times it’s height. what is the volume of the cylinder
Answer:
Step-by-step explanation:
Answer:
Check Below
Step-by-step explanation:
given things : 1. height of cone = 22* 1/4 feet or 89/4 feet
2. diameter of cylinder = 2* 2/5 times of height
= 12/5 times of height or 12/5 * 89/4
= 89*3/5 feet
now formula of volume of cone = Pi R² * H
= (3.14) ( D/2)² * H
= (3.14)* (89*3/10)² * 89/4
= (3.14) * (26.7)² * 22.25
= (3.14) * 712.89 * 22.25
= (49806.06)

Which of the following are solutions to the inequality below? Select all that apply.
5 ≥ s
Answer:
: w ≤ - 6
Step-by-step explanation:
Line segment EF begins at (-1,5) and ends at (-1, -3). The segment is translated to the right 4 units and down
2 units to form line segment E'F.
Enter the length, in units, of line segment E'F.
The coordinates for the line segment E'F' are (3, 3) and (3, -5) and the length of the segment E'F' is 8 units.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
Line segment EF begins at (-1, 5) and ends at (-1, -3). The segment is translated right 4 units and down 2 units to form line segment E'F'. Then the coordinate of E' and F' will be:
E' = (-1 + 4, 5 – 2) = (3, 3)
F' = (-1 + 4, -3 - 2) = (3, -5)
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The length of the E'F' = √(0 + 64) = 8 units
Thus, the coordinates for the line segment E'F' are (3, 3) and (3, -5) and the length of the segment E'F' is 8 units.

Using the equation, y=5x²−17x −12, determine whether the parabola opens upward or downward.
Answer:
opens upwards
Step-by-step explanation:
given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
given
y = 5x² - 17x - 12
with a = 5 > 0
then parabola opens upward
A cube has a volume of 1000 cubic feet. what is the length of an edge of the cube? show how you found the answer. please help
volume = (side length)³
Alternatively we could say that;
Side length = ∛volume
(we have just found the cube root of both sides here, remember we can do what we like to an equation, as long as we do the same to both sides!)
Because we cubed side length to get volume, side length must be the cubic root of the volume, the ∛.
We know that the volume is 1000 cubic feet, so;
Side length = ∛1000
∛1000 = 10
So the length of an edge of the cube is 10 feet.

Find the surface area of the rectangular prism.
4 yd
3 yd
3 yd
Answer:
[tex]A = 66\ yd^2[/tex]
Step-by-step explanation:
You can either add up all the areas of the faces of the rectangular prism, or you can use the following formula:
[tex]A = 2(wl+hl+hw)\\A = 2(3 \times 3 + 4 \times 3 + 4 \times 3)\\A = 2(9+12+12)\\A = 2(33)\\A = 66[/tex]
Answer:
The surface area of the rectangular prism is [tex]66\ yd^2[/tex]
Step-by-step explanation:
Step 1: Find the area of the front and back
[tex]A = l * w[/tex]
[tex]A = 3\ yd * 4\ yd[/tex]
[tex]A = 12\ yd^2 * 2[/tex]
[tex]A = 24\ yd^2[/tex]
Step 2: Find the area of the top and bottom
[tex]A = l * w[/tex]
[tex]A = 3\ yd * 3\ yd[/tex]
[tex]A = 9\ yd^2 * 2[/tex]
[tex]A = 18\ yd^2[/tex]
Step 3: Find the area of the left and right sides
[tex]A = l * w[/tex]
[tex]A = 3\ yd * 4\ yd[/tex]
[tex]A = 12\ yd^2 * 2[/tex]
[tex]A = 24\ yd^2[/tex]
Step 4: Total area
[tex]A_{total} = 24\ yd^2 + 18\ yd^2 + 24\ yd^2[/tex]
[tex]A_{total}= 66\ yd^2[/tex]
Answer: The surface area of the rectangular prism is [tex]66\ yd^2[/tex]

the hypotenuse of a right triangle has endpoints (2,7) and (11,-5) what is the perumeter of the triangle?
Answer:
36 units
Step-by-step explanation:
Using the coordinates, you can find the length of each leg of the triangle.
Find the distance between the x-coordinates, 2 and 11 by subtracting.
11 - 2 = 9.
Find the distance between the y-coordinates, 7 and -5 by subtracting.
7 - (-5)
7 + 5 = 12
The two legs of the right triangle are 9 and 12.
Use the pythagorean theorom to find the hypotenuse.
[tex]a^{2} +b^{2} =c^{2} \\9^{2} +12x^{2} =c^{2} \\81 + 144 = c^{2} \\225 = c^{2} \\\sqrt{225}=\sqrt{c^{2} } \\c = 15[/tex]
The three sides of the triangle are 9, 12, and 15. To find the perimeter, add the sides together.
9 + 12 + 15 = 36

Answer:
P = 12 + 2π cm
Step-by-step explanation:
arc length is calculated as
arc = circumference × fraction of circle
the angle subtended at the centre of the sector = 360° - 300° = 60° , then
arc = 2πr × [tex]\frac{60}{360}[/tex]
= 2π × 6 × [tex]\frac{1}{6}[/tex]
= 2π
the perimeter (P) = 6 + 6 + 2π = 12 + 2π
