Answer:
28 short race volunteers
76 long race volunteers
Step-by-step explanation:
Let :
Short races = a
Long races = b
LAST YEAR:
7a + 8b = 804 - - - - (1)
THIS YEAR:
11a + 5b = 688 - - - (2)
Multiply (1) by 5 and (2) by 8
35a + 40b = 4020
88a + 40b = 5504
Subtract
-53a = - 1484
a = 1484 / 53
a = 28
Put a = 28 in equation (1)
7(28) + 8b = 804
196 + 8b = 804
8b = 804 - 196
8b = 608
b = 76

Answer:
2 to the 40th power is conventionally written as 240, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 2^40. 109 9511627776. number or base 103 power, index, or exponent = 10 x 10 x 10 = 1,000. Writing 2 as a factor one million times would be a very time-consuming and tedious task. A better way to approach this is to use exponents. Exponential notation is an easier way to write a number as a product of many factors. Index Notation and Powers of 10. The exponent (or index or power) of a number says. how many times to use the number in a multiplication. 102 means 10 × 10 = 100. (It says 10 is used 2 times in the multiplication)
