If it takes four men three hours to dig two holes, how long does it take one man to dig three holes?
Answer:
it will take one man 18 hours to dig the three holes
Step-by-step explanation:
To solve this problem, we can set up a simple relation as follows:
4 men dig two holes in 3hours
4 men will dig 1 hole in x hours.
2 holes => 3 hours
1 hole => x hours
x = (1 X 3)/2 = 1.5 hours
Therefore, 4 men will dig 1 hole in 1.5 hours.
From this, we can find how long it will take 1 man to dig 1 hole
if 4men dig a hole in 1.5 hours
1 man will dig 1 hole in x hours
4 X 1.5 = 6 hours
1 man will dig 1 hole in 6 hours
finally, if 1 man digs a hole in 6 hours, it will take the man 6 hours X 3 to dig 3 holes = 18hours
it will take one man 18 hours to dig the three holes

Find the equation for the
following parabola.
Vertex (2, -1)
Focus (2, 3)
Answer:
(x−2)^2=16(y+1)
Step-by-step explanation:
The equation for the parabola is (x - 2)² = 16(y + 1) if the vertex of the parabola is (2, -1) and focus of the parabola is (2, 3) option (D) is correct.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have:
The vertex of the parabola = (2, -1)
The focus of the parabola = (2, 3)
As we know, the vertex form of the parabola is given by:
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
(x - 2)² = 4a(y - (-1))
(x - 2)² = 4a(y + 1)
The value of a can be found using the formula:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
(c, d) = (2, 3)
a = √[(2-2)² + (3-(-1))²]
a = √ (3+1)²]
a = 4
(x - 2)² = 4(4)(y + 1)
(x - 2)² = 16(y + 1)
Thus, the equation for the parabola is (x - 2)² = 16(y + 1) if the vertex of the parabola is (2, -1) and focus of the parabola is (2, 3) option (D) is correct.

Step-by-step explanation:
The original image would be the blue triangle, so you need to see how many units it takes to get to the red triangle.
Let's focus on R and R'.
You need to move 6 units to the right, and 4 units down to get from R to R'.
It would then be the same for the other two points.

The mean age of the members of a baseball team is 28, the median age is 24, and the ages range from 20 to 45. Which of the following statements is best supported by the data?
Answer:
half are 28 or older
Step-by-step explanation:
also, im taking a math test i have the same question on my jupiter and the same amount of questions. could u send me the answers to all the questions if thats possible :) thx sm
The required statement by the details is an option (D) that half of the players are 24 or younger.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
We are given that the mean age of the members of a baseball team is 28 and the median age is 24. We can use this information to eliminate some answer choices.
Option (A) states that more than half of the players are older than 28. Since the median age is 24 and the ages range from 20 to 45, this option is not supported by the data.
Option (B) states that half of the players are 28 or older. Since the median age is 24 and the ages range from 20 to 45, this option is not supported by the data.
Option (C) states that the mode of the data is less than 28. We do not have enough information to determine the mode, so this option could be true or false.
Option (D) states that half of the players are 24 or younger. Since the median age is 24, this option is supported by the data.
Therefore, the best-supported statement by the facts is option (D) that half of the players are 24 or younger.

Rayyan shares Rs 2000 between his two friends Anas and Ahsan. The ratio of Anas’s share to Ahsan’s share is 6:4
How much money do they each receive?
Answer:
Anas= RS 1200
Ahsan= RS 800
Step-by-step explanation:
Given data
Amount= Rs 2000
Ration= 6:4
Combined ratio = 6+4= 10
Let us apply the part to all method to solve for the individual amount
For Anas
2000/10= x/6
cross multiply
10x= 2000*6
10x= 12000
x= 12000/10
x= 1200
For Ahsan
2000/10= x/4
cross multiply
10x= 2000*4
10x= 8000
x= 8000/10
x= 800
Ethan spent 12.5% of the money in his pocket on dinner. His dinner cost $15.25. How much did he have in his pocket? Group of answer choices $102.00 $172.36 $190.63 $122.00
Answer:
$122
Step-by-step explanation:
Let total money in his pocket = $ x
12.5% of x = $ 15.25
[tex]\frac{12.5}{100}*x= 15.25[/tex]
Multiply both sides by 100
12.5 *x = 15.25*100
125.5 *x = 1525
Divide both sides by 125.5
[tex]x = \frac{1525}{12.5}\\\\[/tex]
x = $ 122

System of equations
160 = 2W + 2L
W = L - 16
Solution to system of equations
W = 32 ft
L = 48 ft
Explanation:
The width is 16 feet less than the length, so the appropriate equation for that is ...
... W = L - 16
Using this expression for W, we can substitute into the equation for perimeter:
... 160 = 2(L - 16) + 2L
... 160 = 4L -32 . . . . . . . collect terms
... 192 = 4L . . . . . . . . . . add 32
... 48 = L . . . . . . . . . . . . divide by 4
... W = 48 -16 = 32 . . . . find W using the relation with L
Length is 48 ft; width is 32 ft.

If the slope is 3 and one ordered pair on the line is (2,9), what is the equation?
I'll give you brainliest if it's correct!
Answer:
y = 3x+3
Step-by-step explanation:
we can find the equation of the line with this formula:
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point and m the slope
so we have
y-9 = 3(x-2)
y = 3x-6+9
y = 3x + 3
