9514 1404 393

Answer:

  n = 4

Step-by-step explanation:

Of the 40 people, half are women, so there are 20 women.

There are 5 times as many women as men, so 20/5 = 4 are men.

The remainder are children, so there are 20-4 = 16 children.

The ratio of children to men is ...

  children : men = 16 : 4 = 4 : 1 = n : 1 . . . . . . . . remove a factor of 4 from 16:4

The value of n is 4.

A cinema has 3 screens.last saturday there were 500 visitors
mafiozo [28]

Answer:

200 screen 1

125 screen 2

175 screen 3

Distribution of 500 visitors =100% attendees.

We remove a zero to find 1/10th. By converting  500 }  50/10   =  10 x 50

Step-by-step explanation:

when you add up; 40/10 +  25/10 = 4.0 + 2.5

and show 7.5 is the same as  a + b + 1 x 100

and above 7.5  = 175/100 = 1 .75

Or use the counter  x = multiply by 50

40/10 + 25/10 = 6.5

6.5-10 = 3.5

        x =3.5 x 50

For this last one we can pose new question where 300 visitors was the original total then create new data for new question.

where x = multiply by 30 and create all to tenths etc.

We subtract the shown tenths only to find the total

Then same will apply above with new data.

Select three side lengths, in centimeters (cm), that can form a right triangle. Use the Pythagorean Theorem.
lawyer [7]

Answer:

Hey there!

You can make a right triangle by the sides 6, 8, and 10. The most famous pythagorean triplet is the 3, 4, 5 triangle. Increasing the size of this triangle by a scale factor of 2 makes the sides 6, 8, and 10.

Hope this helps :)

Answer:

Hope this helps! :')

Step-by-step explanation:

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply
