Answer:
3:4
Step-by-step explanation:
there are 6 boys for every 8 girls, so the initial ratio is 6:8. however, this can be simplified by finding a number both 6 and 8 are evenly divisible by. In this case, you can divide the ratio by 2. 6/2 = 3 and 8/2 = 4, which is why the simplified form is 3:4

Answer:
a) 29.6%
b)29.9%
Step-by-step explanation:
Here, we want to change the values to percentage form
a) we have this as;
21/71 * 100% = 29.6%
b) we have thus as;
46/154 * 100% = 29.9%
Let L be length and W be width.
L = 5 + W
So the perimeter is equal to 2L + 2W and that equals 50 feet.
So substitute L with 5 + W to get:
2(5+W) + 2W = 50
10 +2W + 2W = 50
10 + 4W = 50
4W = 40
W = 10
Which means:
L = 15
So the area is just LxW which is 15x10 = 150 feet squared
I hope this helps you
100+42+8
100+50
