Answer:
248 miles
Step-by-step explanation:
we know that
After 3.5 hours ,Pasha had traveled 217 miles
so
using proportion
Find out how many miles she will have traveled after 4 hours

X*80+y*60= 50*74
x +y =50 | * ( -60)
80x + 60y= 50*74
-60x - 60y=-50*60
---------------------------
20x= 50*(74-60)=50*14
x=50*14/20=35 pounds of 80 cents tea
y=50-35=15 pounds of 60 cents tea
Answer:
280 degrees.
Step-by-step explanation:
To convert radians to degrees we multiply by 180/pi:
angle O = 14pi/ 9 * 180 / pi
= 14*180 / 9
= 280 degrees.
Answer:
X' = (2, -3)
Y' = (7, -9)
Z' = (10, -2)
Step-by-step explanation:
to find the translation of each point substitute the x and y with the the numbers
eg; X ( -5,2) the x is 5 and the y is 2
so -5 + 7 = 2 (the x value)
2 - 5 = -3 ( the y value)
