Juan ordered 20 pizzas for a party. 45% of the pizzas have 8 slices each. The remaining 55% of the pizzas have 12 slices each. C

ruslelena [56]

Step-by-step explanation:

Model:

s = slices

x = pizzas ordered

s = .8(.45x) + .12(.55x)

Now plugin 20 for x and you will get the total number of slices.

s = .8(.45x) + .12(.55x)

s = .8(.45(20)) + .12(.55(20))

s = 204 slices

Note, we could make this model different and smaller but I chose this method because it demonstrates what is going on with the word problem

Answer:

2: 99° 3: 81° 4: 81°

Step-by-step explanation:

2 is supplementary to 1 so subtract 81 from 180 = 99.

3 is vertical angle with 1 so they are equal

4 is alternate interior angle with 3 so they are equal

hope this helps stay safe :)

For your rock collection display, you want to have at most 25 samples.

mezya [45]

Answer:

$\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.$

The graph is attached.

Step-by-step explanation:

Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.

You know that you want to to have at most 25 samples, then:

$y\leq 25-x$

And you want to have at least 3 times as many sedimentary samples as

metamorphic samples, then:

$y\geq 3x$

Therefore, the system of inequalities that model the situation is:

$\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.$

The y-intercept of the line $y=25-x$ is:

$y=25-(0)\\\\y=25$

And the x-intercept is:

$0= 25-x\\\\x=25$

Knowing this, you can graph the line

The y-intercept of the line $y= 3x$ is:

$y=3(0)\\\\y=0$

And the x-intercept is:

$0= 3x\\\\x=0$

Knowing this, you can graph the line.

Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.
