Answer:
both these equations are the examples of associative property.
#1 is the example of associative property with respect to multiplication.
#2 is the example of associative property with respect to addition.
It is y=2x+2. The slope is 2 and the y intercept is 2
Answer:
mean= m7.8571428571429 Mode 1, 2
Step-by-step explanation:
The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores. The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
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>
