Question

Write the formulas that may be used to solve the problems below, then solve.
A. How long will it take Karen to drive 975 miles if her average speed is 65 miles per hour?

B. A rectangular pool has a tile border around its perimeter that measures 66 feet. If the length of the pool is 18 feet, what is the width of the pool?

C. A current of 0.05 amps is driven by a voltage of 0.6 volts. What is the resistance measured in ohms?

Answer 4

question A\[Average~speed=\frac{ distance }{ time~taken }\]given that the distance travelled=975 miles..and the average speed=65 miles/per hour..plug in all the value to find the time taken travelled by Karen..

Answer 5

\[time~taken=\frac{ distance }{ average~speed }\]

Answer 6

\[time~taken=\frac{ 975miles }{ 65miles~h^{-1} }\]

Answer 7

\[time~taken=\frac{ 15\cancel{975miles} }{ 1\cancel{65miles}h^{-1} }\]

Answer 8

\[time~taken=?\]

Answer 9

question B\[perimeter~of~a~rectangular~pool=2(l+w)\]where
l=length
w=width
given that the perimeter of a rectangular pool=66 feet..and the length of the pool=18 feet..plug in all the value to find the width of the rectangular pool..

Answer 10

\[perimeter=66\]

Answer 11

\[2(l+w)=66\]

Answer 12

\[2[(18)+w]=66\]

Answer 13

divide both sides by 2

Answer 14

\[18+w=33\]

Answer 15

subtract both sides by 18

Answer 16

\[w=33-18\]

Answer 17

\[w=?\]

Answer 18

question C\[R=\frac{ V }{ I }\]where
R=resistance
V=voltage
I=current
given that current=0.05A..and voltage=0.6V...plug inall the values to find the value of R..

Answer 19

\[R=\frac{ 0.6 }{ 0.05 }\]

Answer 20

\[R=?\]

Answer 21

question D\[T_{(F)}=T_{(C)}\times1.8+32\]where
T_(F)=Fahrenheit
T_(C)=Celsius
given that the patient's temperature=39 dgree celsius=T_(C)..plug in all the values to find the temperature in degrees fahrenheit..

Answer 22

\[T_{(F)}=39\times1.8+32\]

Answer 23

\[T_{(F)}=70.2+32\]

Answer 24

\[T_{(F)}=?\]

Answer 25

solve it! @Lilah
