The shorter piece is 37 cm

The longer piece is 48 cm:

Step-by-step explanation:

Divide 85 cm by 2 = 42.5

Divide 11 cm by 2 = 5.5

Add them together = 48 cm

85 cm - 48 cm = 37 cm

Stephen spends 10% of his salary on food, 15% of it on transportation, and saves the remaining 2000. what is his salary?
Ber [7]

Answer:

His salary is $2666.68

Step-by-step explanation:

First add the percent of the costs.       10% + 15% = 25%

Then subtract 25% from 100% to find the percentage that 2,000 is of the total salary.                                                           100% - 25% = 75%

$2,000 is 75% of the total salary. Divide 2,000 by three to find the amount of money 25% of the salary is. ( 75% is 3/4 of 100)                                                         2,000 divided by 3 = $666.67

25% of the salary is $666.67

Multiple that by 4 and you get the total salary.

666.67•4= $2666.68

Are you sure those were all the correct numbers because that was not a very nice number at the end there lol but that answer is correct with the numbers you gave me.

Perimeter of a triangle is 27cm,if two sides measure 9cm and 7.8cm,find the measure of third side?
fredd [130]

Answer:

10.2cm

Step-by-step explanation:

Perimeter is the sum of the lengths of all sides.

1st side: 9cm

2nd side: 7.8cm

Perimeter: 27cm

Perimeter = 1st + 2nd +3rd side of a triangle

27cm = 9cm +7.8cm + 3rd side

3rd side = 27cm - 9cm -7.8cm

              = 10.2cm
