Answer:
b - 1/4 = 3 1/2
Step-by-step explanation:
b - 1/4 = 3 1/2
b - 1/4 = (3 + 1/2)
4b = 15
b = 15/
4
= 3.75
There are bunch of factors of both. Here are the GCF and LCM.
Greatest Common Factor (GCF) = 12
Least Common Factor (LCM) = 120
The answer is 45%
1. Calculate how many ml of blue pigment are in 4ml of ink A if it contains <span>10% blue pigment:
4 ml is 100%
a ml = 10%
4 ml : 100% = a : 10%
a = 4 ml * 10% : 100% = 0.4 ml
2.</span> Calculate how many ml of blue pigment are in 10ml of ink A if it contains x% blue pigment:
10 ml is 100%
b ml = x%
10 ml : 100% = b : x%
b = 10 ml * x% : 100% = x/10 ml
3. 2. Calculate how many ml of blue pigment are in 14ml (because Four milliliters of ink A is added to 10 milliliters of ink B) of total mixture if it contains 35% blue pigment:
14 ml is 100%
t ml = 35%
14 ml : 100% = t : 35%
t = 14 ml * 35% : 100% = 4.9 ml
4. <span>What percentage of blue pigment is in the mixture of the two inks:
a + b = t
0.4 + x/10 = 4.9
x/10 = 4.9 - 0.4
x/10 = 4.5
x = 4.5 * 10 = 45</span>
Answer: 1 inch : 4 feet
Step-by-step explanation:
Given: A room in the hotel is 6 inches long in the drawing.
The actual room is 24 feet long.
i.e. 6 inches in the drawing = 24 feet (in actual)
1 inch in drawing = 
feet
i.e. 1 inch in drawing = 4 feet
The scale of drawing Percy used for the drawing:
1 inch : 4 feet
