You could say that you spent (purchased) 85% of the money that you had.
You spent a total of $85.
If you create the fraction 85/100, that is the same as saying you spent 85% of the money.
Answer:
b
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ( where r is the radius )
Here r = 3, thus
V =
π × 3³
=
π × 27 = 4π × 9 = 36π in³ → b
Answer:
the law of cosines with ABC
Answer:
-1
f (x) = -3(x + 5)
Step-by-step explanation:
1) in f(x) = 1/3x-5, replace f(x)= with y= as follows: y = (1/3)x - 5
2) interchange x and y, obtaining: x = (1/3)y - 5
3) solve this result for y: (1/3)y = -x - 5, or -(x + 5). Next, multiply both sides by 3 to eliminate the fraction (1/3): y = -3(x + 5)
4) replace y with the symbol for "inverse of f(x);
-1
f (x) = -3(x + 5)
Step-by-step explanation:
oh, come one ! you can literally see that one ...
a full rotation on a clock is a full circle and stands therefore for 360°.
for the minute hand these 360° represent 60 minutes.
4 minutes of 60 is a fraction, a ratio, and the same ratio applies then also to 360°.
4/60 = 1/15
360 × 1/15 = 24°
so, 4 minutes represent 24°.
