Answer:
Let the number be x.
x doubled is 2x, and 2x is 20 greater than 200. So, we have this:
2x = 200 + 20
2x = 220
x = 110.
Answer:
She should mix 9 g of powder
Step-by-step explanation:
From the question, we can have a ratio for powder to water
we have 5 g of powder mixed with 45 cm^3 of water
So, for every 1 g, we have 5g/45 cm^3
we have 9 cm^3
So let’s relate this to the bigger water mix
Recall from above; we have the mixing as 1 g per 9 cm^2 of water
1g per 9 cm^2
x g per 81 cm^2
81 * 1 = x * 9
9x = 81
x = 81/9
x = 9g
Answer:
L= 0.83 in
Step-by-step explanation:
Width= 1.2 in when length = 1 in
Required
Determine the length when width = 1 in
First, we need to determine the ratio
Ratio = 
Ratio = 
Ratio = 1.2 ---(1)
Let the required length be represented with L
So:
Ratio = 
Ratio =
---(2)
Equate (1) and (2)
= 1.2
Multiply through by 1.2
L *
= 1.2 * L
1 = 1.2 * L
Divide through by 1.2
L = 
L = 0.83 in (Approximated)
