Answer:
845
Step-by-step explanation:
Because they are similar triangles you can find the scale factor first.
395/553 is the scale factor
(395/553)*280=200
(395/553)*350=250
200+250+395 = 845
Answer:
Step-by-step explanation:
There are 1000 m in 1 km, and 3600 s in 1 h, so the speed conversion is ...
The car's speed is 90 km/h.
__
In 2 hours, the car will travel ...
distance = speed · time = (90 km/h)(2 h) = 180 km
-1/y = 2/5y. The change from -1 to 2 would be -2, so we now that the change from y to 5y would also have to be -2. -2 = -10 so you multiply by 5. After doing the same to the top you would come to the conclusion that the LCD would be 5y. Hope this helps!
Answer:
7 wins to 3 losses, so 7:3, 7/3, or 7 to 3 depending on how you want to phrase it.
I will assume the question is log (8x) = 4/3
This means, "The exponent we put on 10 to get 8x is 4/3"
10^(4/3) = 8x
x = [10^(4/3)]/8
x = 2.69
log (8*2.69) = 4/3 ?
log (21.52) = 4/3
1.33 = 4/3
1.33 = 1.33
