Answer:
€445.5
Step-by-step explanation:
First we calculate the increase percentage and the increase.
Increase = 450 + (10%*450)
Now we must calculate the percentage of the increase.
Increase percentage = 10% of €450 = 450*0.1 = 45
Increase = 450 + 45 = €495
Since the decrease happens to the <em>new </em>number, the decrease and the decrease percentage <em>both </em>must be to the new changed number, which is 495
Decrease = 495 - (10%*495)
Again we must calculate the percentage of the decrease.
Decrease percentage = 10%*495 = 0.1*495 = 49.5
Decrease = 495 - 49.5 = 445.5
So, the value of Erika's ski chalet after the two changes = €445.5
Answer:
D.51.34°
Step-by-step explanation:
tan(angle wvx)=WX/WV
i.e,tan(angle wvx)=5/4=1.25
i.e,angle wvx=tan⁻¹(1.25)
=51.34°
Answer: hundredth
Step-by-step explanation:
You have units tenths then hundredths
Slope intercept is y = mx + b
b is 1470
2x + 3y = 1470
2x (-2x) +3y = 1470 - 2x
3y = -2x + 1470
3y/3 = (-2x + 1470)/3
y = -2/3x + 490
hope this helps
