Answer:
B) 4 miles
Step-by-step explanation:
the big triangle CAB and small triangle CED are simular (given)
this means the ratio between their corresponding sides will be the same.
find corresponding sides with alternate interior angle theorem
m CDE= m CBA
vertical angles theorem
m ACB = m DCE
therefore, AC corresponds to CE
find ratio of sides
7 miles = 36960 feet
36960/ corresponding side 21 ft
36960/ 21= 1780 ft
multiply by 1780 to get from small side to big side
small side CE = 12 ft
12*1780
=21120 ft =AC (in ft)
convert to miles (ft to miles is ft/5280)
21120/5280
=4 miles
hope this helps

If Tan A=5/12 then find cot A, cos A and Sin A
Answers
Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
Answer:
Step-by-step explanation:
[tex]tan \ A = \frac{5}{12}=\frac{opposite \ site}{adjacent \ side}[/tex]
hypotenuse² = (opposite side)² + (adjacent side)²
= 5² + 12²
= 25 + 144
= 169
hypotenuse = √169 = √13*13 = 13
[tex]Cot \ A = \frac{adjacent \ side}{opposite \ side}=\frac{12}{5}\\\\Cos \ A = \frac{adjacent \ side}{hypotenuse}=\frac{12}{13}\\\\Sin \ A = \frac{opposite \ side}{hypotenuse}=\frac{5}{13}[/tex]

"If the radius of the closed cone is doubled, show algebraically how this affects the surface area in comparison to the original cone."
How do I do this question?
Answers
Answer:
It would help to have the cone area formula:
Area = PI * radius * slant height
Let's say the height is 12cm radius is 5 cm
which makes the (slant height)^2 = 12^2 + 5^2 = 169
slant height = 13
and surface area = PI * 5 * 12 = 188.4955592154
If radius = 10 then (slant height)^2 = 12^2 + 10^2 = 244
slant height = 15.6204993518
surface area = PI * 10 * 15.62 = 376.99
376.99 / 188.4955 = 2
So, if radius is doubled, surface area is doubled.

Which is the formula
for the volume
of a cylinder?
A. V = a^2 + b^2 + c^2
B. V = (area of the base)(radius)
C. V = (area of the base)(height)
Answers
Answer: C. V = (area of the base)(height)
This applies to any prism. A cylinder is effectively a prism but the base is a circle rather than a polygon.
The cylindrical volume formula you may be more familiar with is
V = pi*r^2*h
note how the pi*r^2 portion is the area of the circular base. So we can replace the pi*r^2 with "area of the base" to end up with choice C.

Answers
Answer:
Y=4 X= -6 or (-6,4)
Step-by-step explanation:
Okay so
3x+10y=22
-3x-8y=-14
basically, it's like one big equation. First, subtract 3x from -3x which cancels out and gives us 010y minus 8y gives us 2y.22 minus 14 gives us 83x+10y=22
-3x-8y=-14
0+2y=8
Now that we have this, we can solve for y. in order to do this, we have to divide both sides by 2.
[tex] \frac{2y}{2} = \frac{8}{2} [/tex]
From here we know that y=4 because the 2s cancel out leaving y and 8 divided by 2 is 4.
y= 4
Now we can fill in. You can pick any equation for this but I'm going to chose the first one.
3x+10y=22
we can fill in 4 for y
3x+10(4)=22
3x+40=22
Next we are going to subtract 40 on both sides.
3x+40=22
-40 -40
3x= -18
Next, we're going to divide -18 by 3.
[tex] \frac{3x}{3} = \frac{ - 18}{3} [/tex]
The 3s cancel out leaving us x. -18 divided by 3 is -6.
x= -6
Hope this helped!! :)

calculate, in dollars, how much more Jane pays.
Answers
Answer:
$19.15
Step-by-step explanation:
$1=0.626
$1/0.626=£1
$11.99=$11.99/0.626
=$19.15
Answer:
Step-by-step explanation:
£ 0.626 =$ 1
£1 = $ [tex]\frac{1}{0.625}[/tex]
£ 11.99 = [tex]11.99*\frac{1}{0.625}= \frac{11.99*1000}{0.625*1000}\\\\[/tex]
[tex]= \frac{11990}{626}\\\\[/tex]

19.15 - 16.95 = $2.2

y - 3 = 2(x - 2)
Step-by-step explanation:
Step 1. Solve for slope
m = slope
m = (y2 - y1)/(x2 - x1)
Points: (-2, 3) & (1, 9)
m = (9 - 3)/(1 - - 2)
m = 6/3
m = 2
Step 2. Use the two points and the slope to write the line in point-slope form.
Point-Slope Form: y - y1 = m(x - x1)
Slope-Intercept Form: y = 2x + 7
With the points: (-2, 3) & (1, 9)
Where x1 = -2 y1 = 3, x2 = 1 y2 = 9
Point-Slope Form = y - 3 = 2(x - 2)
