Answer:
25%
Step-by-step explanation:
100% means total amount of people surveyed, which is 300 people total.
We're looking for females who own a blue car, so that's 75 people out of 300.
75/300 = 0.25
Convert the decimal to percent by moving decimal 2 places to the right
Answer is 25%
Answer:
C. 210 miles
Step-by-step explanation:
We have been given that two cars leave Phoenix and travel along roads 90 degrees apart. Car 1 leaves 30 minutes earlier than Car 2 and averages 42 mph.
We will use distance formula and Pythagoras theorem to solve our given problem.
![\text{Distance}=\text{Speed}\times \text{Time}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%7D%3D%5Ctext%7BSpeed%7D%5Ctimes%20%5Ctext%7BTime%7D)
![\text{Distance covered by Car 1 in 3.5 hours}=\frac{42\text{ Miles}}{\text{Hour}}\times \text{3.5 hour}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20covered%20by%20Car%201%20in%203.5%20hours%7D%3D%5Cfrac%7B42%5Ctext%7B%20Miles%7D%7D%7B%5Ctext%7BHour%7D%7D%5Ctimes%20%5Ctext%7B3.5%20hour%7D)
.
Since car 1 leaves 30 minutes before car 2, so car 2 will travel for only 3 hours when car 1 will travel for 3.5 hours.
![\text{Distance covered by Car 2 in 3 hours}=\frac{50\text{ Miles}}{\text{Hour}}\times \text{3 hour}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20covered%20by%20Car%202%20in%203%20hours%7D%3D%5Cfrac%7B50%5Ctext%7B%20Miles%7D%7D%7B%5Ctext%7BHour%7D%7D%5Ctimes%20%5Ctext%7B3%20hour%7D)
![\text{Distance covered by Car 2 in 3 hours}=150\text{ Miles}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20covered%20by%20Car%202%20in%203%20hours%7D%3D150%5Ctext%7B%20Miles%7D)
Since both car travel along roads 90 degree apart, therefore, the distance between both cars after Car 1 has traveled 3.5 hours would be hypotenuse with legs 147 and 150.
![\text{Distance between both cars}=\sqrt{147^2+150^2}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20between%20both%20cars%7D%3D%5Csqrt%7B147%5E2%2B150%5E2%7D)
![\text{Distance between both cars}=\sqrt{21609+22500}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20between%20both%20cars%7D%3D%5Csqrt%7B21609%2B22500%7D)
![\text{Distance between both cars}=\sqrt{44109}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20between%20both%20cars%7D%3D%5Csqrt%7B44109%7D)
![\text{Distance between both cars}=210.021427\approx 210](https://tex.z-dn.net/?f=%5Ctext%7BDistance%20between%20both%20cars%7D%3D210.021427%5Capprox%20210)
Therefore, the both cars will be 210 miles apart and option C is the correct choice.
Answer:
Step-by-step explanation:
So its difficult to show
Y= X-6 so what ever x is, y is six less than that so
X= -4 Y= -10
X= 0 Y=-4
X=4 Y=0
X=8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that
X=-4 Y= -5
X=0 Y= -2
X=4 Y=1
X= 8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= -2
Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.
Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2
X=-8 Y= 0
X= -4 Y = 1
X=0 Y=2
X=4 Y=3
X=8 Y=4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Do this method for 9
y = 2x -3 so whatever x is, y is 2 times that -3
y=2x +1 so whatever x is y is 2 times that +1
y= 2x so whatever x is y is 2 times that
Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them
Make sure to label each line
Hope this helps
