Answer:
2 : 15 x 2 = 4 : 30
Step-by-step explanation:
You get the ratio 4:30 by multiplying both numbers of the original ratio by 2.
2x2= 4
2x15=30
So in conclusion, the answer to the problem is 4 : 30.
We set up a proportion: 12/200= ?/100
Cross multiply:
200*?= 12*100
⇒ ?= 12*100/200= 6
12 is 6% of 200~

Answer:
P = (18a+10b+13) cm
Step-by-step explanation:
Given that,
A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.
We need to find an expression that represents the perimeter of the triangle.
Perimeter = sum of all sides
P = (10a+9) + (8a-3) + (10b+7)
Taking like terms together,
P = (10a+8a)+10b+(9-3+7)
= 18a+10b+13
Hence, the epresssion for the perimeter is (18a+10b+13) cm.
