The length is 15 feet.
Write them both as ratios!
6/10=9/x
6x=90
x=15
Answer:
Yes
Step-by-step explanation:
If an object travels at a constant speed, then the distance traveled is directly proportional to the time spent traveling, with the speed being the constant of proportionality. The circumference of a circle is directly proportional to its diameter, with the constant of proportionality equal to π.
The surface area of the rect. prism shown here can be found as follows:
5*7 = 35 (area of one end). Total area of ends is 2(35) = 70
2(5)d Total area of vertical faces = 10 d
2(7)d Total area of horizontal surfaces = 14 d
Equating the sum of these 6 areas to the given total surface area, 262 m^2, we get:
(70+10d+14d) = 262 m^2.
Simplifying, 70 + 24d = 262 m^2, or 24d = 262-70 m^2.
Simplifying further, 24d = 192 m^2, so that d = 8 meters
Answer: B
Triangle ABC is similar to DEC because:
m<3=m<4 vertically opp angles are equal (Angle)
m<1=m<5 alternate angles between two parallel lines AB and DE (Angle)
m<2=m<6 remaining angle will be equal without any doubt (Angle)
So by AAA similarity ,they are similar
You can factor out 1/2
The expression is: 1/2(a - 8)
