A glass is
Marrrta [24]

total volume of the glass is }x =200cm^3 .

<u>Step-by-step explanation:</u>

Here we have , A glass is  1/4  full. Then 70cm3 of orange juice is poured in.

The glass is now  3/5  full. We need to find that What is the total volume of the glass . Let's find out :

Suppose that volume of glass is x ,so according to question we have the following equation

\frac{x}{4}+70 = \frac{3x}{5} , Now, solve this to find value of x

⇒ \frac{x}{4}+70 = \frac{3x}{5}

⇒ 70 = \frac{3x}{5}- \frac{x}{4}

⇒ 70 = \frac{3x((4)-x(5)}{5(4)}

⇒ 70 = \frac{12x-5x}{20}

⇒ 70(20) = 12x-5x

⇒ 7x = 1400

⇒ \frac{7}{7}x = \frac{1400}{7}

⇒ }x =200cm^3

Therefore, total volume of the glass is }x =200cm^3 .

XY bisects DF at point E. If DE=2y and EF=8y-3, find the value of DF​
nirvana33 [79]

Answer:

Step-by-step explanation:

If XY bisects DF at point E, then DE = EF.

Given DE = 2y and EF = 8y-3

2y = 8y-3

subtract 8y from both sides

2y-8y = 8y-8y-3

-6y = -3

y = 3/6

y = 1/2

y = 0.5

DF = DE+EF

DF= 2y+8y-3

DF = 10y - 3

DF = 10(0.5)-3

DF = 5-3

DF = 2
