E^-0.3 = 0.74 from the calculator
Answer:
5x + 3y = 2
5x - 3y = -22
Step-by-step explanation:yes
-126 = -34 + 2x is the equation you would use. solve for x, which would be -46. it would take 46 minutes for the diver to reach 126 feet below sea level.
1) find the lcd the lcd is 12
2)rewrite the fractions 1/4 and 2/3 using 12 as the denominator (second column) you get 3/12 and 8/12
3) since its confusing to subtract 8/12 from 3/12 you need to borrow one form the 126 doing so is the same as taking 12/12 from 126 this change to 125 and the 12/12 adds to the 3/12 making it 15/12
4) subtract 8/12 form 15/12 to get 7/12
5) subtract 78 form 125 to get 47
6) the answer is 47 7/12
The width of the actual yard is 50 feet wide. Since the scale from the drawing to real life is 1 inch for every 10 feet, simply multiply 1:10 by the same number on both sides to get an equivalent ratio using the given scale. Basically, 1 inch : 10 feet * 5:5 equals 5 inches for every 50 feet.
Alternative:
1 inch = 5 inches
10 feet = ? feet
If you multiply the numerator by 5, you multiply the denominator by five to ensure the ratio and scale are still accurate and equivalent. 10 * 5 = 50.
