Margaret [11]3 years ago

Answer:

<h2>A = 57</h2>

Step-by-step explanation:

Use the Pick's theorem

Let P be a polygon in the plane whose vertices have integer coordinates. Then the area of P can be determined just by counting the lattice points on the interior and boundary of the polygon!

In fact, the area is given by

A=i+\dfrac{b}{2}-1

where <em>i</em> is the number interior lattice points, and<em> b</em> is the number of boundary lattice points.

Look at the picture.

i=50,\ b=16

Substitute:

A=50+\dfrac{16}{2}-1=50+8-1=57

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1
lora16 [44]

The value of x is 1/5

Step-by-step explanation:

In a probability distribution, probability should be between 0  and 1. The probabilities add up to one.

Given probabilities are:

\frac{1}{10}, \frac{1}{5}, \frac{1}{2}, x

The sum of these probabilities will be equal to 1.

So,

To find x,

\frac{1}{10}+\frac{1}{5}+\frac{1}{2}+x = 1\\\frac{1+2+5}{10}+x=1\\\frac{8}{10}+x=1\\x= 1- \frac{8}{10}\\x = 1- \frac{4}{5}\\x= \frac{5-4}{5}\\x=\frac{1}{5}

The value of x is 1/5

An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is
MrRissso [65]

Answer:

First blank- 32000 ounces

Second blank- 2000 pounds

Yes the bridge can hold 1 ton.

Step-by-step explanation:

The ratio of the scale of the model to the real bridge = 1:4

The test model shows the model can take 8000 ounces

The real bridge will therefore take 8000 x 4 = 32000 ounces

16 ounces = 1 pound

32000 ounces =  x pounds

==>  = 32000/16 = 2000 pounds

2000 pounds = 1 ton

therefore the bridge holds 1 ton

Hello there,


So we are trying to find out is the angle ∠BAC in degrees. 

So what we are going to do is. . .25- (2x-10)°.

That answer would be -2x+35.

So ∠BAC= -2x+35°.
Hope this helps.
