Answer:
C.) 20, 40, 4, 56
Step-by-step explanation:
Equation:
.84 as a percentage is 84.5%
84.5% is greater than .500 or 50%
Other answers:
A.) = 47.5%
B.) = 46%
D.) = 42.5%
<h3>
Answer: 28 and 29</h3>
28+29 = 57
=======================================================
Explanation:
n = first number
n+1 = second number
Add up those two items and set the result equal to 57. Solve for n.
first+second = 57
(n) + (n+1) = 57
2n+1 = 57
2n = 57-1
2n = 56
n = 56/2
n = 28
n+1 = 28+1 = 29
The two consecutive whole numbers are 28 and 29
28+29 = 57
Answer: of the order.
Step-by-step explanation:
1. You have that number of carpenters decreases from 5 carpenters to 1 carpenter. Therefore, this decreases by the following factor:
2. The number of days decreases from 8 days to 4 days. Then, the factor is:
3. The order is a furniture, therefore, you can solve the problem as following, where is the part of the order completed by one carpenter in 4 days:
we conclude that the perpendicular line to y = 3x + 2 is the one in option C.
y = (-1/3)*x + 4
<h3>
Which of these lines is perpendicular to the line y = 3x + 2?</h3>
We know that two lines are perpendicular if and only if the slope of one of the lines is equal to the opposite of the inverse of the slope of the other line.
The line equation is:
y = a*x + b
Where a is the slope.
In our case:
y = 3*x + 2
The slope is 3.
Then a line perpendicular to the above one, must have a slope of -(1/3). By looking at the options, we can see that the only one with that slope is the one in option C, which is:
y = (-1/3)*x + 4
So we conclude that the correct option is C.
