40,000,000,000,000

Step-by-step explanation:

Because 100 times 100 is 10,000 times 100 is 1 million 1,000,000 times 100 is 100,000,000 times 100 is 10,000,000,000 times 4000 is 40,000,000,000,000

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at

aksik [14]

The formula for the area of a triangle is
$A=\frac{1}{2}bh$
$\rightarrow\frac{dA}{dt}=\frac{1}{2}(b\frac{dh}{dt}+h\frac{db}{dt})$

We are given:
$\frac{dh}{dt}=2$
$\frac{dA}{dt}=4.5$
$h=9.5$
$A=92$

Plug in:
$4.5=\frac{1}{2}(b*2+9.5\frac{db}{dt})$
We can find $b$ with:
$A=\frac{1}{2}bh\rightarrowb=\frac{2A}{h}=\frac{2*92}{9.5}=\frac{184}{9.5}$
So $4.5=\frac{1}{2}(2*\frac{184}{9.5}+9.5\frac{db}{dt})$
$\rightarrow9=\frac{368}{9.5}+9.5\frac{db}{dt}$
$\rightarrow9-\frac{368}{9.5}=9.5\frac{db}{dt}$
$\rightarrow\frac{db}{dt}=\frac{9-\frac{368}{9.5}}{9.5}\approx-3.130$

So the base is decreasing at a rate of 3.130 cm/minute.

PLEASE HELP ASAP!! CORRECT ANSWERS ONLY PLEASE!!!

frutty [35]

Answer:

In a deck of 52 cards, there are 26 red cards.

The probability that the first drawn card is red:

P(A) = 26/52

Without replacement, the probability that the second drawn card is red:

P(B) = 25/51

Then, this dependent probability is calculated by:

P = P(A) x P(B) = (26/52) x (25/51) = 25/102 = 0.245 = 24.5%

Hope this helps!
