Let x be the common ratio / or scale factor
the sides of the triangle are
5x, 12x and 13x
sum of the sides defines perimeter
that is
5x + 12x + 13x = 15
30x = 15
x = 15/30
x = 0.5
The sides of the triangle are 0.5(5) = 2.5
0.5(12)=6
0.5(13) = 6.5
2.5, 6, 6.5 all in inches
Answer:
0.51cm/s
Step-by-step explanation:
Area of a circle A = πr²
r is the radius
Rate of change of area is expressed as;
dA/dt = dA/dr • dr/dt
dA/dr = 2πr
radius r = 77cm
dA/dt = 79cm²
Get dr/dt
Substitute the given values into the formula
79 = 2π(77)•dr/dt
79 = 154dr/dt
dr/dt = 79/154
dr/dt = 0.51cm/s
Hence the rate of change of the radius is 0.51cm/s
S = 555 I think I’m not 100% sure
Answer:
b
Step-by-step explanation:
Let's use the formula!
-9/5 - 2/5 we get = -11/0
Since it is divided by 0, it is B undefined.
Answer:
No
Step-by-step explanation:
Because the watch is selling for 75% off, the discounted price will be
($)
Then, when you apply your coupon, the new cost will be
($)
So you'll still pay $18.75.
