Answer:
12
Step-by-step explanation:
Do you mean "what does three times four equal"?
3 x 4 = 12
Answer:
33
Step-by-step explanation:
Let
Z---------------- > number of zacks stamps collections for a stamp show
T---------------- > number of teri's stamps collections for a stamp show
P--------------- > number of pacos stamps collections for a stamp show
we know that
Z=(3/10)*30-----------> Z=9
T=(5/6)*18------------ > T=15
P=(3/8)*24------------->P=9
the answer is
number of zacks stamps collections for a stamp show was 9
number of teri's stamps collections for a stamp show was 15
number of pacos stamps collections for a stamp show was 9
In their display were 33 stamps
Answer:
x + 4√(x + 2) + 6
Step-by-step explanation:
All we need to do is expand by using FOIL (First, Outside, Inside, Last):
x + 2 + 2√(x + 2) + 2√(x + 2) + 4
Then we combine like terms to get our final answer:
x + 2 + 4√(x + 2) + 4
x + 4√(x + 2) + 6
Answer:
0.08274 kilograms
Step-by-step explanation:
1 gram = 0.001 kilograms
82.74 grams = 0.08274 kilograms
Hope this helps :)
Answer:
y = (x/(1-x))√(1-x²)
Step-by-step explanation:
The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:
x = r·cos(θ)
y = r·sin(θ)
x² +y² = r²
__
r = sec(θ) -2cos(θ)
r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)
r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²
(x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations
x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor
y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)
![\boxed{y=\dfrac{x\sqrt{1-x^2}}{1-x}}](https://tex.z-dn.net/?f=%5Cboxed%7By%3D%5Cdfrac%7Bx%5Csqrt%7B1-x%5E2%7D%7D%7B1-x%7D%7D)
