Grace's height and the tree's height are related by equivalent ratios
The height of the tree is 2.00 meters
Grace's height is given as:
When she measured the length of the tree's shadow, we have:
--- the length of her shadow
--- the length of the tree's shadow
The height (H) of the tree is calculated using the following equivalent ratio
Substitute known values
Express as fractions
Multiply both sides by 1.65
Simplify
Hence, the approximated height of the tree is 2.00 meters

Answer:
c)
Step-by-step explanation:
the x rate of change is +2 and the y rate of change if -1. slope is always y over x, therefore, do exactly that. put y (-1) over x (2). thus gett in your answer of the slope.
Answer:
l= 234/r
Step-by-step explanation:
Given data
Surface area of cone=734.76 square meters.
The formula for the lateral surface area is
S.A=πrl
substitute the surface area
734.76 = 3.14*r*l
734.76/3.14=rl
234=rl
l= 234/r
Hence, with a value for r, the expression for the slant height l is given as
l= 234/r
Answers:
1/2a= 8
Multiply by 2/1 on both sides
1/2(2/1)a= 8(2/1)
Cross out 1/2 and 2/1 equals to a
a= 16
4n= 32
Divide by 4 for both sides
4n/4= 32/4
n= 8
3x= 36
Divide by 3 for both sides
3x/3= 36/3
x= 12
m/3= 2
Multiply by 3/1 for both sides
3/1*m/3= 2(3/1)
Cross out 3/1 and 3 becomes m
m= 6
x-8= 12
Move -8 to the other side. Sign changes from -8 to +8
x-8+8= 12+8
x= 20
48= 3k
Divide by 3 for both sides
48/3= 3k/3
k= 16
13/b= 0
Multiply by 1/13 for both sides.
13/b( 1/13)= 0(1/13)
b= 0
39= 13y
divide by 13 for both sides
39/13= 13y/13
y= 3
