Answer:
To solve this we calcuclate the total are then we subtract the 4 rectangles area
total area = length × width =10.5 × 10.5 = 110.25 cm²
the rectangles drawn accurately = 2(.5 × 7)
7 cm²
the rectangles drawn not accurately 2(.5 × 10.5)
= 10.5 cm²
so the shaded area = 110.25 - 7 - 10.5 = 92.75 cm²
Answer:
there are 80 students
Step-by-step explanation:
you divide 9 by 90 to find how many teachers there are, then subtract it by 90
Answer:
The 4:6 ratio statement is true.
Step-by-step explanation:
4 bananas: 6 apples
3 x + 9 = 44 - 2 x
subtract 9 from both sides:
3 x + 9 - 9 = 44 - 2x - 9
3 x = -2 x +35
Add 2 x to both sides:
3 x + 2 x = -2 x + 35 + 2 x
5 x = 35
Divide both sides by 5 :
5x / 5 = 35/ 5
x = 7
hope this helps!
Yes it is. When you simplify the girls ratio( 12:30 by 6)you'll get 2:5. When you simplify the boys ratio( 16:40 by 8)you'll get 2:5. So it is the same ratio.
