Jaime Bailey is chair of a department at a college. Jaime has a budget in which 1.4 of the money is for photocopying, 2/5 of the money is for computer-related expenses, and the rest of the money is for student tutors in the foreign languages lab. What fraction of Jaime's budget is for student tutors?

Step-by-step explanation:

7/20

Represent the total budget amount by b.

Then from this b, subtract b/4 and then from the result subtract 2/5:

b - b/4 = (3/4)b; now from this (3/4)b subtract (2/5)b:

Converting these proper fractions to decimal fractions, we get:

0.75b - 0.40b = 0.35b

This tells us that 35/100, or 7/20, of Jaime's budget is for tutors.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
