The height of the tower that was supported with the wire is 132.29 feet.
What is the height of the tower?The tower, the wire and the ground would form a right triangle. A right triangle is a polygon that has three sides. The longest side is the hypotenuse. The other two sides are the length and the base.
In this question, the wire is the hypotenuse, the tower is the length and the ground is the base. Pythagoras theorem would be used to determine the height of the tower.
The Pythagoras theorem: a² + b² = c²
where:
a = length
b = base
c = hypotenuse
a² + 150² = 200²
a² + 22,500 = 40,000
a² = 40,000 - 22,500
a² = 17,500
a = √17,500
a = 132.29 feet

If two dice are rolled one time, find the probability of getting these results. Show all possible combinations. Express the probability as a fraction of 36
A 3 on one die or on both dice
A sum greater than or equal to 10
Step-by-step explanation:
any particular result with 2 dice has a probability of
1/6 × 1/6 = 1/36
a 3 on one die or both simply means at least one 3.
so, if all the 36 different outcomes we are looking at
3 1
3 2
3 3
3 4
3 5
3 6
1 3
2 3
4 3
5 3
6 3
the 3 3 combination can be counted only once !
so, we have 11 desired outcomes out of the possible 36.
so, the probability of getting at least one 3 is
11/36
the sum of at least 10 means the corresponding cases
4 6
5 5
5 6
6 4
6 5
6 6
in this case we don't need to turn this around, because it would be exactly the same outcomes again, and we don't want to count them twice.
so, we have 6 desired outcomes of the 36.
the probability of that is
6/36 = 1/6

He purchases a total of 150 containers of popcorn to sell. After he sells 15 containers, he will make a total profit, after his upfront costs, of $5.50. Cassidy’s profit, after upfront costs, can be modeled by a linear function in the form y=mx+b.
What is Cassidy’s profit if he sells all of the popcorn?
HInt:Substitute 150 for x to find the profit if all the popcorn is sold.
If Cassidy sells all of the popcorn, his profit would be equal to $208.00.
What is the slope-intercept form?Mathematically, the slope-intercept form of a line can be modeled by using this linear function:
y = mx + b
Where:
m represents the slope.x and y are the points.b represents the y-intercept.How to determine Cassidy’s profit?In order to determine Cassidy’s profit, we would have to calculate the cost of the containers of popcorn by using this mathematical expression:
Note: the price tag for a container of popcorn is one dollar and fifty cents.
Cost of containers = revenue - total profit
Cost of containers = 1.50(15) - 5.50
Cost of containers = 22.5 - 5.50
Cost of containers = $17.00
Therefore, the linear function which models Cassidy’s profit is given by:
y = 1.50x - 17
If Cassidy sells all of the popcorn, his profit is given by:
Cassidy’s profit, y = 1.50x - 17
Cassidy’s profit, y = 1.50(150) - 17
Cassidy’s profit, y = 225 - 17

A house mover towed a historic Victorian home 45 miles to locate it on a new site. On his return, without the heavy house in tow, his average speed was 30mph faster and the trip was 2 hours shorter. How fast did he drive in each direction?
The required speed is 45 mph in each direction.
What is speed?
The definition of speed is a measurement of how quickly an object's location changes in any direction. Speed is defined as the ratio of distance to the amount of time it took to cover that distance.
We know that distance=rate*time
d=rt
45=rt
45=(r+30)(t-2)
rt=(r+30)(t-2)
This shows,
rt=rt+30t-2r-60
0=30t-2r-60
if 45=rt, then r=45/t
substitute in the equation
0=30t-2(45/t)-60
multiply both sides by t
0=30t²-90-60t
on solving this quadratic equation, we get t= 3 s, t=-1 s
consider positive value
t=3 hours
45=rt
45=r*3
r=45/3 =15 mph to new site

The interior and corresponding exterior angle of a triangle are always supplementary.
Therefore, we can set the sum of the two given angle measures to 180°:

What is Linear pair?When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. These are also referred to as additional angles.
Given:
m ∠Z = (2m − 12)° and exterior angle ∠Z =(3m + 7)°.

from -2 to -3 = -2 - -3 = 1 unit
reflecting 1 unit over x = -3
-3 - 1 = -4
(-4, -2)
(-2, -2) ⇒ (-2 - -3, -2) ⇒ (1, -2) ⇒ (-3 - 1, -2) → (-4, -2)

The minimum length that you can buy is 7.68 foot and the greatest length that you can buy is 8.32 foot
The length of the planks that lumber stores sell = 8 foot
The error tolerance of the plank = 4%
Then the 4% of the length 8 is

Answer:
m∠1 = 126°
m∠2 = 154°
Step-by-step explanation:
First, find the measure of angle that is supplementary to ∠1. (I will call it ∠A)
We know that the measures of the interior angles of a triangle add to 180°.
Therefore,
m∠A + 96° + 30° = 180°
m∠A + 96° = 150°
m∠A = 54°
From this value, we can solve for m∠1, since it is supplementary to ∠A:
m∠A + m∠1 = 180°
54° + m∠1 = 180°
m∠1 = 126°
To solve for ∠2, we must first solve for the adjacent supplementary angle that I have named ∠B.
First, the measures of the interior angles of a triangle add to 180°:
28° + m∠1 + m∠B = 180°
28° + 126° + m∠B = 180°
m∠B = 26°
Finally, we can solve for m∠2 because it is supplementary to ∠B.
m∠B + m∠2 = 180°
26° + m∠2 = 180°
m∠2 = 154°
