i had 28 of these to do and i need help on 9 i really don't understand please help
1) a motorboat took 3hrs to make a downstream trip with 4mph current. The return trip against the same current took 5hr. Find the speed of the boat in still water.
2) $9500 is invested, part of it at 11% and part of it at 8%.For a certain year, the total yield is $937.00. how much was invested at 11% and how much at 8%.
3)in 1996 a total of 7.0 million tourists visited a city. there were four times as many American tourists as foreign tourists. determine the #of foreign and the # of american tourists.
4)the area of a rectangle with length and width is computed by A(L,W)=LW while its perimeter is calculated by P(L,W)=2L+2W use the method of substitution to solve the system of equations for L and . Consider the length to be the longer side.
A(L,W)=90 P(L,W)=12
5)the area of a rectangle with length and width is computed by A(L,W)=LW while its perimeter is calculated by P(L,W)=2L+2W use the method of substitution to solve the system of equations for L and . Consider the length to be the longer side.
A(L,W)=8 P(L,W)=12
6)approximate graphically the radius and height of a cylindrical container with a volume 80 cubic inches and lateral surface area 75 square inches. find the radius and the height in inches of the cylindrical container.
7) estimate the surface area of a human body with weight and height. use the formula s(wh)=0.007184(w^0.425)(h^0.725) where w is in kilograms and h is in centimeters and s is in square meters ( 1 kilogram= 2.2 pounds and 1 inch= 2.54 centimers) w=143 pounds h=59. what is the surface area in square meters round the answer to two decimal places.
8)estimate the surface area of a human body with weight and height. use the formula s(wh)=0.007184(w^0.425)(h^0.725) where w is in kilograms and h is in centimeters and s is in square meters ( 1 kilogram= 2.2 pounds and 1 inch= 2.54 centimers) w=130 pounds h=72. what is the surface area in square meters round the answer to two decimal places
