John wants to measure the height of a tree. His eye level is 6 feet from the ground. He walks exactly 100 ft from the base of
the tree and looks up. The angle from the Johns eye level to the top of the tree is 33º. How tall is the tree?
Answer:
70.9 feets
Step-by-step explanation:
From trigonometry:
tan θ = opposite /Adjacent
Opposite = tree height, y
Adjacent = vertical distance between eyelevel and tree
tan 33º = y/100
y = 100 * tan 33º
y = 100 * 0.6494075
y = 64.9 feets
Distance between John's eye level and the ground = 6 feets
Total tree height = 6 + 64.9 = 70.9 feets

convert 3684 to standard form
Answer:
3.684 × 103
Step-by-step explanation:
Converting Normal Numbers to Standard Form. To convert large normal numbers to standard form you have to put a decimal point after the first digit and ignore the zeros at the end (if there is another number that is not 0 after the zero(s), don't ignore them). In the example on the right you should end up with 3.844.

find MK
Answer:
MK=32.5
Step-by-step explanation:
Hey There!
I believe that these triangles are similar
So to find MK we want to find the scale factor
To do this we divide
66/30=2.2
Now we want to divide 72.5 by 2.2
72.5/2.2=32.5
therefore MK=32.5
hope this helps!

1. Mike is buying a new video graphics card for his computer. If x represents the
kost prior to an 8.5% sales tax, which expression represents the total cost of the
graphic card?
a. X+0.085x
b. X- 0.085x
c. X+0.085
d. X-0.085
38 points!! Will give crown
Answer:
x + 0.085x
Step-by-step explanation:
Because.. in the last sentence it says the total cost which means add so then you eliminate b and d...so after that before 8.5% it says sales tax...so then that is when you add a x at the end. so it is........x+0.085x.

10. The sum of a certain number and a second number is -42. The first
number minus the second number is 52. Find the numbers.
56
Answer:
the first number and the second number is 5 and -47 respectively
Step-by-step explanation:
Let us assume the first number be x
And, the second number be y
According to the question
x + y = -42
x - y = 52
x = 52 + y
Now put the value of x in the first equation i.e.
x + y = -42
52 + y + y = -42
2y = -42 - 52
2y = -94
y = -47
And, x is
x + y = -42
x -47 = -42
x = 5
Hence, the first number and the second number is 5 and -47 respectively

Answer:
Area of the circle = 616[tex]cm^{2}[/tex]
Volume of the rectangular prism = 416[tex]mm^{3}[/tex]
Step-by-step explanation:
Area of a circle = [tex]\frac{22}{7}r^{2}[/tex] where, r is the radius.
To find the radius, take the half of diameter
[tex]\frac{28}{2} =[/tex] 14
= [tex]\frac{22}{7}[/tex][tex]14^{2}[/tex]
= [tex]\frac{22}{7}[/tex] × 196
= 22 × 28
= 616[tex]cm^{2}[/tex]
Volume of a rectangular prism = length × breadth × height
= 10.4 × 5 × 8
= 416[tex]mm^{3}[/tex]

3.) multiply 2 by 2x and 8
4.) add the like terms on the left hand side to get 25
5.) divided by 4 on both sides
Answer:
2(2x+8)+9=37
4x+16+9=37
4x+25=37
4x=37‐25
4x=12
x=12/4
x=3
Answer:‐ (1)
The solution is x = 3

Find the value of x.
Answer:
x = 30.74
Step-by-step explanation:
39 - 15 = 24
y^2 + 24^2= 36^2
y^2 + 576= 1296
y^2= 720
y= [tex]12\sqrt{5}[/tex]
15^2 + [tex]12\sqrt{5} ^{2}[/tex]= x^2
225 + 720 = x^2
x^2= 945
x = 30.74
