A city water tank holds 20 gallons of water. A technician empties 25% of the tank. How many more gallons of water must be remove

Pavel [41]

20
empties 25%
25%=1/4
1/4 of 20 is 5
20-5=15
15 left
how much more must be removes so it reaches 2/5 of 20
2/5 of 20=40/5=8
15-what=8
minus 15 both sides
-what=-7
multipy-1
what=7

answer is 7 more gallons must be removed

Explain how to find the value of y that would make segment OP parallel to segment LN.

photoshop1234 [79]

Answer:

$y = 36$

Step-by-step explanation:

Given; the triangle above

Required

Find y

This question falls under the topic/subtopic similar triangles where we need to make comparison between similar sides'

But first, it should be noted that triangle MOP is similar to triangle MLN

This implies that

Side MP is similar to MN

Side MO is similar to ML

Mathematically; This can be represented as follows;

$\frac{MP}{MN} = \frac{MO}{ML}$

Where MP =y; MN = y + 18; MO = 28; ML = 28 + 14

Substitute these values in the above expression

$\frac{y}{y+18} = \frac{28}{28+14}$

$\frac{y}{y+18} = \frac{28}{42}$

Multiply both sides by 42

$42 * \frac{y}{y+18} = \frac{28}{42} * 42$

$\frac{42y}{y+18} = \frac{28*42}{42}$

$\frac{42y}{y+18} = 28$

Multiply both sides by y + 18

$(y+18)*\frac{42y}{y+18} = 28 * (y+18)$

$42y = 28 * (y+18)$

Open Bracket

$42y = 28 * y+28 * 18$

$42y = 28y+504$

Subtract 28y from both sides

$42y - 28y = 28y - 28y +504$

$14y = 504$

Divide both sides by 14

$\frac{14y}{14} = \frac{504}{14}$

$y = \frac{504}{14}$

$y = 36$
