(3w-5)(1+w)=0
I need help pls!!

Answers

you need to set both of them equal to zero to find what w is. so its 3w-5=0 you add 5 to get w by itself so then its 3w=5 and then divide by 3 so w= 5/3 
1 + w = 0 so then you subtract one to get to the other side so w = -1 

the final solution is {5/3, -1}
Reorder the terms:

(-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'.

Find the volume of the bag and candle.Round to the nearest tenth

Answers

The volume of the bag will be found by multiplying the length times the width times the height. This would be 5.5 x 3 x 8. The volume of the bag is 20.9 cubic inches. The volume of the candle would be found by using the formula for finding volume of a cylinder. V =pi(approximately 3.14) x r^2 x h, where r is the radius( half the diameter) and h is the height. V = 3.14 x 1.25 x 1.25 x 6. The volume of the cylinder would be 29.4 cubic inches.

how do you do the formula a2+b2=c2

Answers

In the formula a^2 + b^2 = c^2, a is (most often) the height of the triangle, b is the length of the triangle, and c is the last side-length connecting a and b, called the hypotenuse. The formula states that a and b must form a 90 degree angle, and that a^2 + b^2 = c^2. 

So, to find x in this triangle:

x^2 + 8^2 = 12^2
x^2 + 64 = 144
x^2 = 80
x = 8.94

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

60 mph................
Answer: Roman will catch up Jordan after 0.5 h, and they will be 30 miles into the conmute.

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.

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

Hi, to answer this question you need to know that complementary angle will add up to 90 degrees. If the angle of MKW is x, then angle JKL is 2x (twice the measure). The sum of both of these would be 90°. You can show this as x + 2x=90. Simplify this to 3x=90. Then divide by 3 on both sides to get x=30 degrees.

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

The surface area of the triangular prism is?

A. 540 Square Meters

B. 552 Square Meters

C. 576 Square Meters

D. 624 Square Meters

Answers

If I did my math right, the right answer should be that the surface area of this triangular prism is 576 square meters.

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]

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.
