The measure of angle K and L in the first figure is ∠L = 23 degrees and ∠K = 157. Second figure, the measure of ∠K = ∠L = 70 degrees.

What is sum of interior angles?

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

For figure 2 the two lines are parallel to each other, and the line that meets the parallel line at points at M and L are from two equal lines.

Hence, the angle suspended by both are equal, that is:

∠L = ∠M

∠L = 23 degrees.

Now, the ∠K and ∠J are created by two parallel lines; hence they are equal:

∠K = ∠J = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

23 + 23 + x + x = 360

46 + 2x = 360

2x = 360 - 46

x = 157

Hence, the measure of angle K and L is 157 and 23 respectively.

For the second figure, the angle K and L are created by equal length of segments.

∠K = ∠L = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

x + 90 + 130 + x = 360

2x + 220 = 360

2x= 360 - 220

x = 70

Hence, the angle of K and L is 70 degrees.

What is a linear equation?

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given the cost of an 18-inch wreath = $15

cost of a 22-inch wreath = $30

let the number of 18-inch wreaths be x and the number of  22-inch wreaths is y,

the total cost of both wreaths = $645

cost of x 18-inch wreaths = $15x

cost of y  22-inch wreaths = $30y

equation is,

$15x + $30y = $654

and the number of​ 22-inch wreaths sold was four more than twice the number of​ 18-inch wreaths,

y = 4 + 2x

substitute the value of y in the equation

15x + 30y = 645

15x + 30(4 + 2x) = 645

15x + 60x = 645 - 120

75x = 525

x = 525/75

x = 7

and y = 4 + 2x

y = 4 + 2*7

y = 18

Hence store sells 18  22-inch wreaths and 7  18-inch wreaths.

Step-by-step explanation:

first, we split the expression by grouping the first two terms in parentheses and the last two terms in parentheses. this gives us:

[tex](4x^{3}-3x^{2})(-28x+21)[/tex]

next, we factor out the GCF of each group. this gives us:

finally, all you have to do is take each factored-out term and put them together into a group/expression. the leftover expression from both groups is the same value, so you get:

Reducing the completion average  time for Jobs J and K by one day will shorten the overall project completion time by one day, allowing the project to finish one day early.

In order to finish the project one day early, the completion time for Jobs J and K should be reduced by one day. This is because these two jobs are part of the three critical paths of the project. By reducing the completion time for these two jobs by one day, the entire project will be completed one day early.

5. a random sample of 500 subjects measured their systolic blood pressure, and if they were a smoker or not. the goal is to evaluate if average systolic blood pressure differs by smoking status. summary sample statistics on the dataset follow:

Answers

There is a difference in average systolic blood pressure between smokers and non-smokers.

To evaluate if average systolic blood pressure differs by smoking status, we need to calculate the mean systolic blood pressure for both smokers and non-smokers. We can calculate the mean systolic blood pressure for smokers by taking the sum of systolic blood pressure values for all smokers in the sample, divided by the number of smokers in the sample. This formula can be written as:

Mean Systolic Blood Pressure for Smokers = (Sum of Systolic Blood Pressure Values for all Smokers) / (Number of Smokers)

Similarly, we can calculate the mean systolic blood pressure for non-smokers by taking the sum of systolic blood pressure values for all non-smokers in the sample, divided by the number of non-smokers in the sample. This formula can be written as:

Mean Systolic Blood Pressure for Non-Smokers = (Sum of Systolic Blood Pressure Values for all Non-Smokers) / (Number of Non-Smokers)

Once we have calculated the mean systolic blood pressure for both smokers and non-smokers, we can compare the two means to evaluate if there is a difference in average systolic blood pressure between smokers and non-smokers.

Because it’s a right triangle, we will be using sine, cosine, or tangent to find the missing side (vertical).
We will use tangent because tangent is opposite/adjacent. We have the adjacent side, and we need to find the opposite side.
So let’s solve the first one:
tan20degrees=x/8
x=2.9ft

And now the second:
tan35degrees=y/8
y=5.6ft

Now subtract the second by the first to find the difference in height:

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 5 m/s.
h=2+5t-5t^2
The ball's height of (in meters) after seconds is given by the following. Find all values of for which the ball's height is 3 meters.

Answers

Answer: The height of the ball (in meters) after t seconds is given by the equation h = 2 + 5t - 5t^2. We can use this equation to find the values of t for which the ball's height is 3 meters.

We need to find the values of t that make h = 3, so we can substitute 3 for h in the equation:

3 = 2 + 5t - 5t^2

Then we can solve for t by moving all the terms to one side of the equation and factoring it:

-5t^2 + 5t - 1 = 0

And we can use the quadratic formula to find the solutions of this equation:

t = (5 +/- sqrt(5^2 - 4*(-1)(-1)))/ 2(-1)

t = (5 +/- sqrt(25 + 4))/ -2

t = (5 +/- sqrt(29))/ -2

The solutions of this equation are t = (5 +/- sqrt(29))/ -2

Since the time, t, is a real value the square root of 29 should be positive.

The values of t for which the ball's height is 3 meters are not real values, so there's no time when the ball's height is 3 meters.

Two airplanes leave Philadelphia for Rochester. The first airplane to leave travels at an average speed of 590 kilometers per hour. The second airplane, which leaves 3 hours later, travels at an average speed of 650 kilometers per hour. How long does it take the second airplane to overtake the first?

Answers

it would take 29.5 hours the second airplane to overtake the first.

What is Speed?

speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.

Given, Two airplanes leave Philadelphia for Rochester. The first airplane to leave travels at an average speed of 590 kilometers per hour. The second airplane, which leaves 3 hours later, travels at an average speed of 650 kilometers per hour.

So, in 3 hours first airplane will reach at;

Distance = speed *time

Distance = 590 * 3

Distance travels by first airplane in 3 hours will be = 1770 km

Since, Relative speed of given two planes = 650 - 590

Relative speed of given two planes = 60 km/hour

To reach 1770 km it would take  = 1770/60 hours

Thus,

To reach 1770 km it would take  = 29.5 hours

therefore, it would take 29.5 hours the second airplane to overtake the first.

How many pounds of eggplant should the caterer​ purchase?

First, let's find how many kilograms are needed. We know that the recipe recomends using 0.7kg per person, and there are 70 guests, so an estimate of the mass needed is:

M = 70*0.7kg = 49 kg

Now weneedto do a change of units, we know that:

1 kg =  2.2 lb

Then we can rewrite:

49 kg = 49*(2.2 lb) = 107.8 lb

The caterer should purchase 107.8 pounds
