This is all I understand
Part A. 4x+3x=7x
-5+9=4 Part a is 7x+4
5 squared +12 squared= 13squared 25+144=169
10 + 24 /=/ 28 one common ratio is 5 12 13 this does not match up
15+36= 39 5 12 13 ratio
50 120 and 130 5 12 13 ratio
Answer:
Ocean currents act as conveyor belts of warm and cold water,
Step-by-step explanation:
sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. ... The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
We know that
[the circumference of a circle]=2*pi*r
r=2 ft
[the circumference of a circle]=2*pi*2------> 12.56 ft
if 360° (full circle) has a length of-----------> 12.56 ft
72°---------------------------------> X
x=72*12.56/360-------< x=2.512 ft
1 ft----------> 12 in
2.512 ft-----> x
x=2.512*12------> x=30.14 in-----> x=30 in
the answer is
30 in
X=10
