Answer:
$0.40
Step-by-step explanation:
1st week total: 12.99 + 10.50 + 9.89 + 6.90 + 7.58 = $47.86
5 days total so the mean of 1st week: 47.86 / 5 = $9.57
2nd week, 2 more in total of 1st week = $47.86 + $ 2 = $49.86
The mean of 2nd week: 49.86 / 5 = $9.97
$9.97 - $9.57 = $0.40
2nd week increased 40 cents or $0.40
-3.143 is equivalent to -(3143/1000)
Answer:
36/25
Step-by-step explanation:
7 multiplied by 3 multiplied by 2 whole over 7 multiplied by 5, the whole raised to the power of 2 multiplied by 7 to the power of 0 over 5 to the power of negative 3, whole to the power of 3 multiplied by 5 to the power of negative 9
((7 * 3 * 2)/(7 * 5))^2 * (7^0/5^-3)^3 * 5^-9 =
= (42/35)^2 * (1 * 5^3)^3 * 5^-9
= (6/5)^2 * 5^9* 5^-9
= 36/25 * 5^0
= 36/25
[- 3r²s² - 4sr² + 4rs - 8] is the resultant answer when we subtract the linear equation (7sr²+10-13r²s²) from (3r²s+ 4rs+2-16r²s²).
<h3>What are linear equations?</h3>
- A linear equation in one variable is a mathematical expression for an equation with only one variable.
- While any two real integers can represent A and B, the ambiguous variable x has just one possible value.
- The formula is Ax + B = 0.
- 9x + 78 = 18 is an example of a linear equation with just one variable.
So, we have:
- (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)
Now, calculate as follows:
- = (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)
- = 3r²s+ 4rs+2-16r²s² - 7sr²- 10 + 13r²s²
- = 13r²s² - 16r²s² - 7sr² + 3r²s + 4rs - 10 + 2
- = - 3r²s² - 4sr² + 4rs - 8
Therefore, [- 3r²s² - 4sr² + 4rs - 8] is the resultant answer when we subtract the linear equation (7sr²+10-13r²s²) from (3r²s+ 4rs+2-16r²s²).
