What is the slope of a line that is perpendicular to the line y = 1/6 x + 4? The slope of the line is .
Answer:
-6
Step-by-step explanation:
The slope of a perpendicular line has the slope of the opposite and reciprocal of the current line. We would get -1/6 and then -6.

A wagon is being pulled by a force of 15 pounds. How
much work is done in moving the wagon 50 feet if the
handle makes an angle of 40° with the ground?
11.49 foot-pounds
38.30 foot-pounds
574.53 foot-pounds
750.00 foot-pounds
Answer:
C. 574.53
Step-by-step explanation:
Option C) is correct work done = 574.53.
Force = 15 pounds
distance = 50 feet
Ф = 40°
work done is product of force and cosine of displacement.
work done = force x displacement x cosФ
= 15 x 50 x cos40
= 15 x 50 x 0.76
= 574.53
Thus the required work done is 574.53 to pull the wagon.

Calculate the distance between the point (-8,0) and (-5, 3) in the coordinate plane.
Round your answer to the nearest hundredth
Distance:
The distance between (-8,0) and (-5,3) in the coordinate plane is 9 units.
Given that the coordinates of points in the coordinate plane are (-8,0) and (-5,3).
We are required to find the distance between the given points.
Distance is basically a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to physical length or an estimation based on other criteria.
Distance between (-8,0) and (-5,3)=[tex]\sqrt{(-5+8)^{2} +(3-0)^{2} }[/tex]
=[tex]\sqrt{3^{2} +3^{2} }[/tex]
=[tex]\sqrt{9+9}[/tex]
=[tex]\sqrt{81}[/tex]
=9 units
Hence the distance between (-8,0) and (-5,3) in the coordinate plane is 9 units.

Suppose lines EF and GH are reflected over the line y = x to form the lines JK and LM. Which statement would be true about the lines?
A.
Line JK and line LM will be parallel.
B.
Line JK and line LM will be perpendicular.
C.
The slope of line JK will be the same as the slope of line EF.
D.
The slope of line LM will be the negative reciprocal of the slope of line GH.
Answer:
A.
Step-by-step explanation:
I believe the answer is A. (Line JK and line LM will be parallel) because lines EF and GH are parallel. Therefore if the are just reflected, the new set of lines will also be parallel.
EF: (-9,1) (-4,9)
[tex]\frac{1-9}{-9+4}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6
GH: (-5,-2) (0,6)

3. Metal is made using Copper, zine and lead in the ratio 13:6:1, the mass of the zinc is 90kg, calculate
1) the total mass of metal
2) the mass of the copper
3) the mass of the lead as a % of the total mass of the metal
Answer:
1) 150 kg
2) 97.5 kg
3) 5%
Step-by-step explanation:
Ratios of each metal to total mass of metal can be computed by dividing its corresponding value by the sum of all the values in the ratio
The ratio of zinc to metal = 6/(13 + 6 + 1) = 6/20 = 3/10
Let the total mass of the metal be X
Then mass of zinc = (3/5)X = 90 kg (given)
1) Multiplying both sides by 5/3 gives X = 5/3 x 90 = 150 kg which is the total mass of metal
2) Ratio of copper to metal mass = 13/20
Mass of copper = 13/20 x 150 = 97.5 kg
3) Mass of lead as a ratio of metal = 1/20 = 0.05
As percentage, multiply by 100 to get 0.05 x 100 = 5%

Blake earns $3,200 each month. He pays
$600 per month for housing, $300 per
month for a car loan, and $150 per month in
other debt payments. Find Blake's debt-to-
income ratio to the nearest tenth of a
percent.
A. 32.8%
B. 32.1%
C. 33.9%
D. 33.4%
Answer:
A. 32.8%
Step-by-step explanation:
Blake's incomes are $3,200 each month.
His debts are:
$600 per month for housing
$300 per month for a car loan
$150 per month in other debt payments
Total payments: $600+$300+$150=$1,050
The debt-to-income ratio is calculated by:
[tex]\displaystyle r=\frac{1,050}{3,200}\cdot 100\%[/tex]
r = 32.8%

find the median of this set of numbers 5,11,2,12,4,2
Step-by-step explanation:
2,2,4,5,11,12
the median is 5
Answer:
2, 2, 4, 5, 11, 12 (put the numbers from least to greatest)
since it's an even set of numbers, the median is between two of the numbers. so find where the middle is by counting how many numbers you have, and then dividing by 2. in this case it's 3, so there should be 3 values on either side of the median. so the median is between 4 and 5. So you add those two values together and divide by 2 (because that's how many numbers you added) and you get 4.5 as your median.

Joe collects Pokemon cards. He already has 100 and buys a dozen more each week when he goes to the store. Jessica also collects Pokemon cards. She has 130 cards, and buys 6 more each week at the store.After how many weeks would the two kids have the same amount of cards?
Answer:
5 weeks
Step-by-step explanation:
To find the answer to this question we have to write an equation for both situation and put them equal to each other.
Let's write an equation for Joe:
12x + 100
Now, for Jessica
6x + 130
Next, put them equal to each other:
12x + 100 = 6x + 130
Solve:
12x + 100 = 6x + 130
6x + 100 = 130
6x = 30
x = 5
Therefore, it will take 5 weeks for Joe and Jessica to have the same amount of cards.
Check:
12(5) + 100 = 6(5) + 130
60 + 100 = 30 + 130
160 = 160
I hope this helps!!
