Answer:
E' (1, -2)
Step-by-step explanation:
This is a counterclockwise rotation of 270, or a clockwise rotation of 90. A point that undergoes a 270 degree rotation follows this pattern:
(x, y) --> (y, -x)
(2, 1) --> (1, -2)
Answer:
the faster train = 137 mph
the slower train = 117 mph
Step-by-step explanation:
Givens
The distance travelled is 1270 km
The rate of one train = r
The rate of the other train = r - 20
The time to travel a total of 1270 miles is 5 hours.
Formula
d = r * t
5*r + 5*(r - 20) = 1270
Solution
5*r + 5*(r - 20) = 1270 Remove the brackets
5r + 5r - 100 = 1270 Add 100 to both sides
10r - 100 + 100 = 1270+100 Combine
10r = 1370 Divide by 10
r = 1370/10
r = 137
Answer:
<u><em>Corral 4</em></u>
Step-by-step explanation:
we need to divide the area of the corral by the Number of animals In order To know the dedicated space for each animal
Corral 1 :
(50×40)÷110 = 18.181818181818 < 20
Then it doesn’t meet the requirements.
Corral 2 :
(60×35)÷115 = 18.260869565217 < 20
Then it doesn’t meet the requirements
Corral 3 :
(55×45)÷125 = 19.8 < 20
Then it doesn’t meet the requirements
Corral 4 :
(65×40)÷130 = 20
Then It meets the requirements
