y-y1=m(x-x1)

y-1=2(x-1)

y=2x-2+1

y=2x-1

Dave has 10 poker chips, 6 of which are red and the other 4 of which are white. Dave likes to stack his chips and flip them over

Marina86 [1]

The number of 10 chips stacks that Dave can make if two stacks are not considered distinct is 110.

The solution

To get the symmetric stacks, one has to subtract the symmetric stacks to know the ones that are asymmetric.

The symmetric are flipped. Given that they are double counted what we have to do is to divide through by 2.

6/2 = 3

10/2 = 5

4/2 = 2

1/2(10C6) - (5C3) + (5C3)

0.5(210-10+10)

= 110

The diagram shows a triangle.<br> 490<br> 880<br> What is the value of v?<br> V =

Step2247 [10]

Answer:

43°

Step-by-step explanation:

The first thing you should do is make the equation. We should know that the sum of all the angles is 180. So it should look like this...

$49+88+x=180$

Combine like terms:

$137+x=180$

Subtract the 137 on both sides:

$x= 43$

That's it the value of v is 43°.

Find the surface area

Semmy [17]

Answer:

The surface area is $198.75\ ft^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the bottom</u>

$A = s^2$

$A = (7.5\ ft)^2$

$A = 56.25\ ft^2$

<u>Step 2: Determine the area of the triangles</u>

$A = \frac{h * b}{2}$

$A = \frac{9.5\ ft * \frac{7.5\ ft}{2}}{2}$

$A=\frac{9.5\ ft*3.75\ ft}{2}$

$A = 17.8125\ ft^2$

There are two of these right triangles on every side which means that we have 8 of these triangles so we multiply the area that we got by 8.

$A = 17.8125\ ft^2 * 8$

$A=142.5\ ft^2$

<u>Step 3: Combine the area to get the surface area</u>

$A_{total}=56.25\ ft^2+142.5\ ft^2$

$A_{total}=198.75\ ft^2$

Answer: The surface area is $198.75\ ft^2$
