Answer:
x = 9
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle, then
the segment is half the length of the 3rd side , that is
3x = 0.5 × 54 = 27 ( divide both sides by 3 )
x = 9
Anyone know how to do this?
Answer:
y = -1/2 x + 25
The relationship is linear, but it takes some doing.
Step-by-step explanation:
Remark
This is a very interesting problem. I've never seen one quite like it. There is probably a much better way of solving it, but I did not discover it.
You have to introduce another variable which I labeled as z.
Let time = x
Let distance = y
Let the step away from the starting point = z which will be the same for x and y. So 18 and 16 the step away from the start is 3.
So as the time increases, the distance decreases. What we are going to do sort of resembles a parametric relationship.
t starts with 10
x = 10 + 4*(z - 1) and increases by 4 with each step
d starts with 20 and decreases by 2 with each step
y = 20 - (z - 1)*2
Now solve for z in each of the forgoing equations.
x = 10 + 4z - 4
x = 6 + 4z
x - 6 = 4z
(x - 6)/4 = z
y = 20 - 2z + 2
y = 22 - 2z
y - 22 = - 2z
(y - 22)/-2 = z
Since the zs must be kept the same, the left sides are equated
(x - 6)/4 = (y - 22)/-2 Cross multiply
-2(x - 6) = 4(y - 22) Remove the brackets.
-2x + 12 = 4y - 88 add 88 to both sides.
-2x + 100 = 4y Switch the sides
4y = - 2x + 100 Divide by 4
y = -1/2 x + 25
Now for sure you have to try this.
Let x = 14
y = -1/2 * 14 + 25
y = -7 + 25
y = 18
Try another one
Let x = 22
y = -1/2 * 22 + 25
y = - 11 + 25
y = 14
Those two at least check.

Answer:
12,13.5,15,16.5,18,19.5
Step-by-step explanation:
just add 1.5
sum of 12.5 and product of 36
I mean 2 variables add up to 12.5
and multiply to 12.5
(x+y)=12.5
X ×Y=36
What is value of x and y
Answer:
(4.5, 8) and (8, 4.5)
Step-by-step explanation:
Given the equations
(x+y)=12.5 ... 1
X ×Y=36 .... 2
From 2, Y = 36/X
Substitute into 1
x+ 36/x = 12.5
x^2 + 36 = 12.5x
x^2 - 12.5x + 36 = 0
10x^2 - 125x + 360 = 0
2x^2 - 25x + 72 = 0
Factorize
2x^2 - 16x - 9x + 72 = 0
2x(x-8)-9(x-8) = 0
2x-9 = 0 and x-8 = 0
x = 9/2 and x = 8
when x = 9/2
Y = 36/(9/2)
Y = 36 * 2/9
Y = 8
When x = 8
Y = 36/X
Y = 36/8
Y = 4.5
Hence the solutions are (4.5, 8) and (8, 4.5)

A bus traveled 330 miles between two cities. If the bus traveled for 6 hours, how
many miles did the bus travel per hour?
Answer:
55 miles per hour
Step-by-step explanation:
.......ur welcome.......
330÷6=55
we divide the amount of miles by the time it took the bust to travel
A bus traveled 330 miles between two cities. If the bus traveled for 6 hours,, The bus will travel approximately 55 miles per hour.
To determine the number of miles the bus traveled per hour, we need to divide the total distance traveled by the time taken.
Given:
Total distance traveled = 330 miles
Time taken = 6 hours
To find the miles per hour, we divide the total distance traveled by the time taken:
Miles per hour = Total distance traveled / Time taken
Miles per hour = 330 miles / 6 hours
Miles per hour ≈ 55 miles per hour
Therefore, the bus traveled approximately 55 miles per hour.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Hypotenuse² = Base² + Length²
The height of the building is 32.8 feet
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
If you place a 26-foot ladder against the top of a building and the bottom of the ladder is 20 feet from the bottom of the building.
This can be written as,
Hypotenuse = 26 feet
Base = 20 feet
Height = height of the building
Now,
Applying the Pythagorean theorem.
Hypotenuse² = Base² + Length²
26² = 20² + Height²
Height² = 676 + 400
Height² = 1076
Height = √1076
Height = 32.8 feet
Thus,
The height of the building is 32.8 feet

The Venn diagram shows the results of two events resulting from rolling a number cube.
Events C and D are____.
conditional and dependent
independent
dependent
conditional
Events C and D are conditional and dependent events.
What can we say about events C and D?By looking at the Venn diagram, we can see that C is the event where the outcome of the dice is even.
While D is the event where the outcome is odd.
So events C and D have no common elements.
Now, the value of these events is related in any way?
if C is true (the number is even) then D must be false.If C is false, then D must be true.Then the events are dependent and conditional, the correct option is the first one.
