(3w-5)(1+w)=0
I need help pls!!
Answers
1 + w = 0 so then you subtract one to get to the other side so w = -1
the final solution is {5/3, -1}
(-5 + 3w)(1 + -1w) = 0
Multiply (-5 + 3w) * (1 + -1w)
(-5(1 + -1w) + 3w * (1 + -1w)) = 0
((1 * -5 + -1w * -5) + 3w * (1 + -1w)) = 0
((-5 + 5w) + 3w * (1 + -1w)) = 0
(-5 + 5w + (1 * 3w + -1w * 3w)) = 0
(-5 + 5w + (3w + -3w2)) = 0
Combine like terms: 5w + 3w = 8w
(-5 + 8w + -3w2) = 0
Solving
-5 + 8w + -3w2 = 0
Solving for variable 'w'.
Factor a trinomial.
(-5 + 3w)(1 + -1w) = 0

Final answer:
The area of a triangle with a base of 166 mm and height of 930.0 mm is found by converting the measurements to meters and using the formula A = 1/2 × base × height. It calculates out to be 0.07719 m² and should be reported as 0.0772 m² to match the least number of significant figures provided in the measurements.
Explanation:
To calculate the area of a triangle, you use the formula A = 1/2 × base × height. Given the base is 166 mm and the height is 930.0 mm, first, you need to convert the measurements to meters by dividing them by 1000 (since there are 1000 millimeters in a meter), which gives us 0.166 m for the base and 0.930 m for the height. Then you plug these values into the formula:
A = 1/2 × (0.166 m) × (0.930 m)
So the area of the triangle is:
A = 1/2 × 0.15438 m²
A = 0.07719 m²
This result should be reported with the proper number of significant figures. Given that the base was provided to three significant figures and the height to four, the area should also be reported to three significant figures since the number of significant figures in the answer is determined by the measurement with the fewest significant figures. Therefore:
Area = 0.0772 m²

Answers
Step 1: Arrange the data given in ascending order, that is from least to greatest.
Given data:
[tex] 42, \; 51, \; 54, \; 46,\; 49, \; 53,\; 52, \; 37, \; 33, \; 36, \; 50, \; 41,\; 50,\; 38\\ \\ [/tex]
Data in ascending order:

Step 2: Find the median (Q2). The median is the value exactly in the middle of an ordered set of numbers .If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
Since in our problem we have 14 datas, we need to pick the middle most numbers and find the average of the same.
[tex] Median =\frac{46+49}{2} =\frac{95}{2} =47.5 [/tex]
The median is called Q2 and equal to 47.5
Step 3: Find the lower quartile (Q1). Considering the values to the left of the median(Q2), the median to those values is the Q1 and called as Lower quartile.
[tex] Q1=38 [/tex]
Step 4: Find the upper quartile (Q3). Considering the values to the right of the median(Q2), the median to those values is the Q3 and called as Upper quartile.
[tex] Q3=51 [/tex]
Conclusion:
Using the above details we need to plot the box and whisker plot attached with this problem.

Angle JKL and MKQ are complementary angles.
The measure if angle JKL is twice the measure of angke MKQ.
Write one equation to find x, the measure if angle MKQ, and then solve for x
Enter your equation and your solution in the space provided
Answers
The equation of the complementary angles can be represented as 2x + x = 90° and the measure of ∠MKQ is 30 degrees.
What are complementary angles?
Complementary angles are angles that sum up to 90 degrees. The angles complement each other.
Therefore,
∠JKL + ∠MKQ = 90°
let
∠MKQ = x
Hence,
∠JKL = 2x
Therefore,
2x + x = 90°
3x = 90
divide both sides by 3
3x / 3 = 90 / 3
x = 30

Jordan and Roman travel the same route to work. Jordan leaves work one morning and drives at a rate,r, of 56 mph. Roman leaves the house soon after, when Jordan has already traveled 2 mo. Roman drives at a rate of 60 mph. How long after Jordan leaves home well Roman catch up to her? How many miles into the commute Will this occur
Answers
Explanation:
1) Data:
Jordan's speed: r1 = 56 mi / h
Roman's speed: r2 = 60 mi / h
Jordan's initial position: 2 miles
Roman's initial position: 0 miles
2) Formula:
Both motions are at constant speed, so rate = distance / time
Position = Initial position + distance run = initial position + rate * time
3) Solution:
Jordan's position, x1 = 2 mi + 56 mi / h * t
Roman's position, x2 = 0 mi + 60 mi/h * t = 60 mi / h
They start driving at the same time, so their times are equal.
When Roman catch up Jordan their position are equal => x1 = x2
=> 2 + 56t = 60 t
=> 60t - 56t = 2
=> 4t = 2
=> t = 2/4 = 0.5 hours
Now you can calculate the position of both in the commute:
From Jordan's rate: x1 = 2 mi + 56 mi /h * 0.5 h = 2mi + 28mi = 30 mi
From Roman's rate: x2 = 60 mi/h * 0.5 h = 30 mi
Answer: Roman will catch up Jordan after 0.5 h, and they will be 30 miles into the conmute.
