PLEASE HELP/ANSWER! From 1980 to 1990, Lior’s weight increased by 25%. If his weight was k kilograms in 1990, what was it in 198

Elena-2011 [213]

The weight in 1980 is $\frac{4k}{5}$ kilograms

Solution:

From 1980 to 1990, Lior’s weight increased by 25%

His weight is "k" kilograms in 1990

To find: weight in 1980

This is a percentage increase problem

Let "x" be the weight in kilograms in 1980

The percentage increase is given by formula:

$\text{Percentage increase } = \frac{\text{Final value - initial value}}{\text{initial value}} \times 100$

Here,

Initial value in 1980 = x

Final value in 1990 = k

Percentage increase = 25 %

Substituting the values in formula,

$25 = \frac{k-x}{x} \times 100\\\\25x = 100(k-x)\\\\x = 4(k-x)\\\\x = 4k - 4x\\\\5x = 4k\\\\x = \frac{4k}{5}$

Thus the weight in kilograms in 1980 is $\frac{4k}{5}$

Find the values of x and y

pantera1 [17]

Answer:

x = 15°

y = 59°

Step-by-step explanation:

Angles at a right angle add up to 90°

41 + y = 90

y = 90 - 41

y = 59°

Angles in a triangle add up to 180°

41 + (2x - 9) + 7x + 13 = 180

41 + 13 - 9 + 2x + 7x = 180

45 + 9x = 180

9x = 180 - 45

9x = 135

x = 135/9

x = 15°
