Mary is standing out on the balcony of her apartment which is 40 feet above the ground and looks up at a 31° angle to see her friend Sue who is standing on her balcony. If Mary and Sue's apartments are 20 feet apart from one another, how high off the ground is Sue?
Answers
Answer:
52 feet
Step-by-step explanation:
This situation can be represented by the attached figure as in the answer area.
Let M be the location of Mary.
Let S be the location of Sue.
Distance between apartments is given as 20 feet.
Distance between ground and balcony of Mary is 40 feet.
There is a right angled [tex]\triangle MOS[/tex].
[tex]\angle OMS = 31^\circ[/tex]
To find:
The distance SO + 40 feet.
We can use tangent ratio here in right angled [tex]\triangle MOS[/tex].
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tan31^\circ = \dfrac{SO}{MO}\\\Rightarrow tan31^\circ = \dfrac{SO}{20}\\\Rightarrow SO=20\times 0.6\\\Rightarrow \bold{SO=12\ ft}[/tex]
Height of Sue above ground = 40+12 = 52 feet

The angle of elevation of top of a tower from a point on the ground, which is 30 m away from the foot of the tower is 30°. The length of the tower is a.√3 m b.2√3 m c.5√3m d.10√3 m
Answers
Answer: d
Step-by-step explanation:
Note that the distance to the tower and the height of the tower create a right triangle at the base of the tower. The equation to find the height of a right triangle is to multiply the length times the tangent of angle β.
Given:
b = a · tanβ
tan(30°) = √3/3
Step 1: Solve
b = (30/1) · (√3/3)
b = (30 · √3) / (1 · 3)
b = (30√3) / (3)
b = 10√3
Divers erected a cage in a shape of an upright cylinder on rhe ocean floor for protection. The diameter of the base measures 32 feet. How much space on the ocean floor does the cage have
Answers
Answer:
The cage will cover an area of 805 ft^2 on the Ocean floor
Step-by-step explanation:
To calculate the amount of space the cage has on the Ocean floor, we calculate the area of the base of the cylinder
Mathematically, that will be pi * d^2/4
= 22/7 * (32 * 32)/4
= 22/7 * 256 = 804.5714285714286
The cage will cover an area of 805 ft^2 on the ocean floor

Jessica wants to spend less than $50.00 per month on her cell phone bill. Write an inequality that shows how many text messages Jessica must limit herself to in order to keep her monthly bill less than $50.00. Use the symbol for your inequality.
Answers
Missing part of question:
Jessica pays a flat rate of $20 for her cell phone and is charged $0.05 for every text she sends.
Answer:
20.00 + 0.05x < 50.00
Step-by-step explanation:
Given
Base Amount = $20
Rate = $0.05 per text
Budget = Less than $50.00
Required
Write an inequality that represents the scenario
Let x represents the number of texts
To solve this, the base amount when added to the amount paid for x text must be LESS THAN Jessica's budget.
Mathematically, we have:
Base Amount + Rate * x < Budget
Substitute values for Base Amount, Rate and Budget, this gives:.
20.00 + 0.05 * x < 50.00
20.00 + 0.05x < 50.00
Hence, the inequality that represents the scenario is 20.00 + 0.05x < 50.00
Solving further for x, we have:
20.00 + 0.05x < 50.00
Collect Like Terms
0.05x < 50.00 - 20.00
0.05x < 30.00
Solve for x
x < 30.00/0.05
x < 600
This means that she must send less than 600 text messages.

Answers
Answer:
Look down!!
Step-by-step explanation:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.
Ex.
4=2+2
y=4
x=2
Hope this helps!!
Answer:
Step-by-step explanation:
the y intercept would be 0,2
to find the x intercept plug in a 0 for y
0=-x+2
-2=-x
x=2
the x intercept would be 2,0
so 2,0 0,2 plot those points and draw a line through that. would look something like this
A gardener is planting two types of trees: Type A is 10 feet tall and grows at a rate of 19 inches per year. Type B is 4 feet tall and grows at a rate of 25 inches per year. Algebraically determine exactly how many years it will take for these trees to be the same height.
Answers
Answer:
It'll take 12 years
Step-by-step explanation:
Given
Type A:
[tex]Initial\ Height = 10ft[/tex]
[tex]Growth = 19in[/tex]
Type B:
[tex]Initial\ Height = 4ft[/tex]
[tex]Growth = 25in[/tex]
Required
Determine the years they'll reach the same height
First, convert feet to inches in both measurements (this is done by multiplying measurement by 12):
Type A:
[tex]Initial\ Height = 10ft[/tex]
[tex]Initial\ Height = 10 * 12in[/tex]
[tex]Initial\ Height = 120in[/tex]
Type B:
[tex]Initial\ Height = 4ft[/tex]
[tex]Initial\ Height = 4 * 12in[/tex]
[tex]Initial\ Height = 48in[/tex]
The height at any year from both trees is calculated using
[tex]Height = Iniital\ Height + Growth * x[/tex]
Where x represents the year;
For Type A:
[tex]Height = 120+ 19 * x[/tex]
[tex]Height = 120+ 19x[/tex]
For Type B:
[tex]Height = 48+ 25 * x[/tex]
[tex]Height = 48+ 25x[/tex]
To get when their height will be equal, we simply equate both expressions:
[tex]48+ 25x = 120 + 19x[/tex]
Collect Like Terms
[tex]25x - 19x= 120 - 48[/tex]
[tex]6x= 72[/tex]
Solve for x
[tex]x = 72/6[/tex]
[tex]x = 12[/tex]
Hence, It'll take 12 years
