Answer:

-20%

Step-by-step explanation:

Given that :

Purchase price = Rs1000

Price sold = 4/5 of the purchase price

Price sold = 4/5 * 1000 = Rs. 800

Profit Percentage :

(price sold - purchase price) / purchase price * 100%

(800 - 1000) / 1000 * 100%

(-200 / 1000) * 100%

-0.2 * 100%

-20%

What is the value of x in the equation

Nastasia [14]

Answer:

Step-by-step explanation:

$\frac{1}{3x} - \frac{1}{2} = 18 \frac{1}{2} \\ \\ \frac{1}{3x} - \frac{1}{2} = \frac{37}{2} \\ \\ \frac{1}{3x} = \frac{37}{2} - \frac{1}{2} \\ \\ \frac{1}{3x} = \frac{37 - 1}{2} \\ \\ \frac{1}{3x} = \frac{36}{2} \\ \\ \frac{1}{3x} = 18 \\ \\ 1 = 54x$

A caterer charger $120 to carter a party for 15 people and $200 for 25 people

Luba_88 [7]

Answer:

y = 8x

Step-by-step explanation:

When the number of people increased by 10, the caterer charged an additional $80. Therefore, we estimate that the cost per person is $8. In order to verify:

$8/person * 15 people = $120. True. $8/person * 25 people = $200. True.

Therefore, if we let x represent the number of people being cater for and y represent the cost, the equation to model the situation is simply y = 8x.

hope it helps!

Triangle E D F has sides that are of varying lengths. Side E D has a length of 4 and side E F has a length of 9.

9966 [12]

Answer:

D E + E F greater-than D F

5 less-than D F less-than 13

Triangle D E F is a scalene triangle

Step-by-step explanation:

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

we have the triangle EDF

where

$ED=4\ units\\EF=9\ units$

Applying the triangle inequality theorem

$ED+EF > DF\\4+9 > DF\\13 > DF\\DF < 13\ units$

$ED+DF > EF\\4+DF > 9\\DF > 5\ units$

The length of DF is the interval -----> (5,13)

The triangle DEF is a scalene triangle (the three length sides are different)

therefore

The statements that are true are

D E + E F greater-than D F

5 less-than D F less-than 13

Triangle D E F is a scalene triangle
