Answer:
a.V=5/6T
b. 350 ml
Step-by-step explanation:
a.
V∝T
or V=kT
where k is a constant.
V=250 ml
T=300° K
250=300 k
k=250/300=5/6
so V=5/6 T
b.
V=5/6 T
=5/6×420
=5×70
=350 ml
Answer:
yes it is true becasue ya so that equals and that is why 5(4 − x) < 3x + 1
Step-by-step explanation:
Answer:
x=-2,2
Step-by-step explanation:
Since this is a quadratic equation, -2 or 2 could be the possible answer
Steps
$3x^2=12$
$\mathrm{Divide\:both\:sides\:by\:}3$
$\frac{3x^2}{3}=\frac{12}{3}$
$\mathrm{Simplify}$
$x^2=4$
$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$
$x=\sqrt{4},\:x=-\sqrt{4}$
Show Steps
$\sqrt{4}=2$
Show Steps
$-\sqrt{4}=-2$
$x=2,\:x=-2$
