Answer:

37 & 27

Step-by-step explanation:

x + y = 64

x - y = 10

=> 2x = 74

=> x = 37

x + y = 64

=> 37 + y = 64

=> y = 64 - 37

=> y = 27

Answer:

37 and 27

Step-by-step explanation:

Lets say that the two numbers are x and y. We get the equations x + y = 64 and x - y = 10. We can then add these two equations together to get, 2x = 74. Then we divide by two on both sides and get x = 37. We then plug this value back into the second equation and get that 37 - y = 10. We can simplify this and we get that y = 27. So our two numbers are 37 and 27.

So we need to find the inequality, Simple!
So we only have 5 dollars. That we cannot change.
But the snadwich, however, we can change how much we buy. But this problem is asking us how many we can buy. So that is an x. So far, we have 2.25x.
Then we have to use the inequality sign 'less than or equal to' because we can buy less or equal to 5 dollars.

So the equation is $2.25x \leq 5$
Then we solve by isolating the x. We divide 2.25 both sides then we get $x \leq 2$

Let A be the area of a circle with radius r. If dr/dt=3, find dA/dt when r=2.

astraxan [27]

$\bf \textit{area of a circle}=A=\pi r^2
\\\\\\
\cfrac{dA}{dt}=\pi \cdot 2r^1\cdot \cfrac{dr}{dt}\implies \cfrac{dA}{dt}=\pi \cdot 2r\cdot \cfrac{dr}{dt}\quad 
\begin{cases}
r=2\\
\frac{dr}{dt}=3
\end{cases}
\\\\\\
\cfrac{dA}{dt}=\pi \cdot 2(2)(3)$

Answer:

$\mathbf{ 0.6 \times 0.5 = 0.3 }$

Step-by-step explanation:

Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.

It is given that $P(M) = 0.6$

Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event $D | M^{c}$ (D given M does not occur) is a null event, i.e
