Answer:

7mm : 3000 mm ; 1 : 428 4/7

Step-by-step explanation:

Given that :

Given a drawing produced using a scale :

7 millimeters = 3 meters ; the scale factor for the drawing

Comparing units in millimeter and units on meter

1000 mm = 1 meter

Hence,

3000 mm = 3 meter

Then, we can say;

7 millimeters = 3000 millimeters

7mm : 3000 mm

Divide through by 7

1 : 428 4/7

Alex Ar [27]

Answer:

Some answers to the reducing fraction sheet

Q14 = 4/5 because divide 12 and 15 by 3

Q15=can't be reduced because 11 is a prime number so it can't be divided by anything

Q17=can't be reduced because 17 is a prime number

Q18=can't be reduced because 13 is a prime number

Q19=38/9 because 114 and 27 would be divided by 3

Q20= -1/1 because you would divide both 14,529 by itself would equal to - 1/1

I can only help you with this sheet I can't help you with the other one hope this was helpful! :)

Answer:

86 cm²

Step-by-step explanation:

Ok, so since 4 circles fit in the square, each circle's diameter must be 10.

Which means the radius of each circle is 5 because 10 ÷ 2 = 5.

Now we can solve for area.

A = πr²

A = 3.14 x 5²

A = 3.14 x 25

A = 78.5 cm²

78.5 cm² is the area of one circle so we multiply that by 4.

78.5 x 4 = 314 cm²

Now we subtract from the area of the square.

20 x 20 = 400 cm²

400 - 314 = 86 cm²
