If there is a spacer between each 5 beads then 1 spacer per inch so 27 inches
27 inches x 5 beads = 135 beads
The raw wquation is
S x B
where s is number of spacers and b us number of beads per inch
this only applies if there is a spacers each inch
The total number of students in the maths club is 40
the number of boys is 5 less than 2 times the amount of girls
to find the number of girls and boys let the number of girls be X.
so 2X-5= the number of boy
so, X+ 2X-5=40
3X-5=40
3X=40+5
3X=45
X=45/3
X=15
the number of girls is 15
and the number of boys is 15x2-5=25 boys
- <em>area of the whole circle = r^2 times pi</em>
- radius is 10 units
- thus, the whole circle's area is 100pi square units.
...and this shape is exactly one quarter, one-fourth, of the whole circle. <em>Why? because of the shape's right angle and radius. (when you multiply 90 times 4, it will equal 360 degrees, which is the angle of a whole circle.)</em>
so 100pi divided by 4 equals 25pi square units of the shape.
ANSWER:
25 pi square units
(or in decimals: multiply 25 by 3.14 which would be 78.5 square units)
Opposite sides of a rectangle are equal so...
perimeter = (2 x 6) + (2 x 4)
perimeter = 12 + 8 = 20 meters
note** area is measured in units squared. Perimeter is measured in units.
