Answer:
there are 18 girls
Step-by-step explanation:
for every 2 boys there are 3 girls
so then you can say 2/5 of the class are boys and 3/5 are girls
and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.
Hope this helps
Answer:
D. w = l − 40; the width increases as the length decreases
Step-by-step explanation:
The formula for the perimeter of a rectangle =
P = 2l + 2w
Where to find the Width, we make w the subject of the formula.
Hence:
P - 2l = 2w
w = P - 2l/2
From the question, P = 80
Hence,
w = 80 - 2l/2
w = 80/2 - 2l/2
w = 40 - l
The width of a rectangle is always the longer side ,hence:
D. w = l − 40; the width increases as the length decreases
Answer:
a) 40 = 8b
b) b = 5
Step-by-step explanation:
(b) 40 = 8 × b
40 ÷ 8 = b
5 = b
Answer:
The answer would be 24,590
