Answer:
71.32 feet
Step-by-step explanation:
We set up a trigonometric function to get height of tree
Distance ,x = 35 feet away from tree base
Angle = 62⁰ at eye level
Y = tan(angle) * x
= Y = tan(62⁰) x 35
Y = 1.881 x 35
Y = 65.82 feet
We add Tamara's height to the total height of the tree
= 65.82feet + 5.5 feet
= 71.32 feet is the height of the tree

Answer:
2008
Step-by-step explanation:
M = 48.81t + 304.30
M = 694.78 Solve for t
694.78 = 48.81t + 304.30 Subtract 304.30 from each side
390.48 = 48.81t Divide each side by 48.81
t = 390.48/48.81
t = 8.00 yr
=====
Year = 2000 + t
Year = 2000 + 8.00
Year = 2008
Military spending hit $694.78 billion at the end of 2008.
Answer:
No, because substituting the given ordered pair doesn't yields two true expressions
Step-by-step explanation:
5x + y = 8
5 + 3 = 8 so thats correct
x + 2y = 5
1 + 6 =7, not 5
so only 1 is correct
Answer:
253cm²
Step-by-step explanation:
Area of the trapezoid = 1/2(b1+b2)*h
Given
h = 22cm
b1 = 10.5cm
b2 = 12.5cm
Substitute
Area of the trapezoid = 1/2(10.5+12.5)*22
Area of the trapezoid = 1/2(23)*22
Area of the trapezoid =11*23
Area of the trapezoid = 253cm²
Hence the area of the trapezoid is 253cm²
