Answer:

  C.  168

Step-by-step explanation:

One of the more useful approaches to multiple choice problems is eliminating the answers that don't make any sense.

You know a square has internal angles of 90 degrees, and that polygons with more sides have larger angles. No internal angle can be more than 180 degrees in a regular polygon. The only answer choice in this range is the correct one:

  C.  168

On your lab bench, you have 2 mystery metal cubes. each cube has a mass of 10.0 grams. cube a has a density of 10 g/cm3. cube b
lianna [129]
To compare both, we find the volume of both cubes as follows:

V of cube A = 10 g / 10 g/cm^3 = 1 cm^3

V of cube B = 10 g / 0.37 g/cm^3 = 27 cm^3

I think the correct answer from the choices listed above is option D. Each edge of cube b is three times larger than cube. Hope this helps. Have a nice day.

Liz and Sara are making cookies for a bake sale. The graph shows the number of cookies that Liz bakes during a 5-hour period.
Radda [10]

<u>Statements</u>

<u>case A)</u> Sara had baked more cookies at the start of the 5 hours than Liz

The statement is True

we know that

At the start of the 5 hours Liz has baked 220 cookies-----> see the graph

Find the number of cookies that Sara has baked for x=5 hours

y=45x+38

y=45*5+38=263

263 > 220

therefore

Sara had baked more cookies at the start of the 5 hours than Liz

<u>case B) </u>Sara bakes 45 cookies each hour

The statement is True

we know that

The number of cookies baked each hour is equal to the slope of the linear equation

The linear equation is

y=45x+38

The slope is m=45\frac{cookies}{hour}

<u>case C)</u> Liz bakes 19 cookies each hour

The statement is false

Find the slope of the Liz graph

The slope is equal to

m=\frac{y2-y1}{x2-x1}

Let

A(0,19)\ B(4,179)

Substitute the values

m=\frac{179-19}{4-0}

m=40\frac{cookies}{hour}

<u>case D)</u> Liz bakes more cookies each hour than Sara

The statement is False

Sara bakes 45 cookies each hour

Liz bakes 40 cookies each hour
