Just need help with C would appreciate it

IrinaVladis [17]

Answer:

85%

Step-by-step explanation:

The students who read less than six magazines would be placed in the intervals: 0-1, 2-3, and 4-5 on the graph. Adding up the total amount in those intervals gives us:

2 + 15 = 17

So, using the answer from b, we can say that 17/20 kids read magazines. Now, we need to convert it into a percent by multiplying by 100:

17/20 *100

17 * 5

85%

Determine whether the polygons to the right are similar. If so, write a similarity statement and give the scale factor. If not

Tamiku [17]

Answer:

(a) Similar polygons; scale factor is 2

(b) Similar polygons; scale factor is 1.5

Step-by-step explanation:

Given

See attachment for polygons

Required

Determine if they are similar or not

Solving (a): The triangle

The angles in both triangles show that the triangles are similar

To calculate the scale factor (k), we simply take corresponding sides.

i.e.

$k = \frac{DF}{BA} = \frac{FE}{AC} = \frac{DE}{BC}$

$k = \frac{6}{3} = \frac{8}{4} = \frac{10}{5}$

$k = 2=2=2$

$k = 2$

The scale factor is 2

Solving (b): The trapezium

The angles in both trapeziums show that the trapeziums are similar

To calculate the scale factor (k), we simply take corresponding sides.

i.e.

$k = \frac{KN}{GJ}$

$k = \frac{6}{4}$

$k = 1.5$

The scale factor is 1.5

5.12 rounded to the nearest whole million

guajiro [1.7K]

Greetings!

In order to round to the nearest million, we will have to move the decimal 5 places to the left.

0.0000512 will be your answer.

Hope this helps!

Geometry math thanks if you help

baherus [9]

Answer: Option B.

Step-by-step explanation:

For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.

The input values are the values of the variable "x" and the output values are the values of the variable "y".

You can observe in the table shown in the picture, that the input value -2 has two different output values:

$x=-2,y=3\\\\x=-2,y=-13$

Notice that the input vale -1 has two different output values too:

$x=-1,y=-1\\\\x=-1,y=-9$

Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.
