How do I find the calculated sum of 1/7 and 1/2

Answers

$(1)/(7)+(1)/(2)=(1 * 2)/(7 * 2)+(1 * 7)/(2 * 7)=(2)/(14)+(7)/(14)=(2+7)/(14)=\boxed{(9)/(14)}$

first make the denomenators (bottom numbers) the same

find the smallest number that 7 and 2 can both go into
the number is 14

multiply both by 1 or x/x where x is the same

1/7 times 1 or
1/7 times 2/2=2/14

1/2 times 1 or
1/2 times 7/7=7/14

sum of numbers
2/14+7/14
add numberators (top numbers)
2+7=9
answer=9/14

A 12-foot tree casts a 22-foot shadow. Find the angle of elevation from the tip of the shadow to the top of the tree. Round the answer to the nearest tenth.

Answers

The angle of elevation from the tip of the shadow to the top of the tree is one of the acute angles of the right triangle. The 22-ft shadow is the length of the adjacent side of the angle and 12-ft tree the opposite side. The angle asked for in the problem is the arctan of 12-ft divided by 22-ft. Thus, the angle of elevation is 28.61 degrees.

62+25=25+___ what's the answer? I'm only 2 grade

Answers

Answer: 62

Step-by-step explanation: 25 appears on both sides, so you can cancel them out. This leaves a 62 on the left side, so there also must be a 62 on the right side.

How tall would I be if i were 54 inches

How tall would I be if i were 58 inches?

How tall would i be if Iwere 59 inches?

Answers

So the question is how tall would a person be in three cases, 54 inches, 58 inches and 59 inches. Since the height measure are feet and inches and one feet has 12 inches, this is the first case: 54 inches = 4*12 inches + 6 inches = 4 feet and 6 inches = 4'6''. Second case: 58 inches= 4*12 + 10 inches= 4 feet and 10 inches = 4'10'' and third case: 59 inches= 4*12 inches + 11 inches= 4 feet and 11 inches = 4'11''.
