Hello!
When doing a 90 degree reparation you flip the coordinates and apply to the sign of the quadrant.
For example, If it flips into quadrant one, they will both be positive.
So, in this case it would be Triangle 4.
Hope this helped!
Answer:
Fell by 25%
Step-by-step explanation:
+20% January
-20% February (20-20 is zero, so we're back to the original price we started at here)
+25% March
?? April
Currently, we are 25% more than what we had, so to get back to normal, the price needs to go down by 25 percent. This will put us back to zero. Put another way...
+20%-20%+25%-25%=0% (Original Price)
Let
x = loaves of bread
y = batches of muffins
You must make a system of two equations with two unknowns that describe the problem
3.5x + 2.5y = 17 --- (1)
0.75x + 0.75y = 4.5 --- (2)
Resolving we have
x = 6-y (from (2))
replacing in (1)
3.5 (6-y) + 2.5y = 17
21 - 3.5y + 2.5y = 17
y = 21-17 = 4
Then substituting in (2)
x = 6-y = 6-4 = 2
Answer
Helena could bake:
2 loaves of bread
4 batches of muffins
Ok...we got 250 people
30% are French, 35% are Americans, 20% are Germans....thats 85%.
This means 15% are from other countries
3 not from other countries...
0.85 * 0.85 * 0.85 = 0.6
0.6(250) = 150 students <===
Step-by-step explanation:
Hence, base = 2 units and hypotenuse = 3 units.
Now, we know that :
Therefore, the required answer is 3/√5.
