Answer:

x = 20

Step-by-step explanation:

x + 2x + 6x = 9x / 180

x=20

triangles = 180

angle 1 = ?

angle 2 = 160?

angle 3 = 20

The value of x in quadrilateral JKLM is 29

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.

The sum of the interior angles in a quadrilateral is 360°

∠J + ∠K + ∠L + ∠M = 360

3X + 90 + 2X + 8 + 4X + 1 = 360

9x + 99 = 360

9x = 360 - 99

9x = 261

x = 261/9

x = 29

In conclusion 29 is the value of x in the quadrilateral.

Quadratic equation :The maximum height reached by Alonzo's ball will be 9m.

What is a quadratic equation?

The equation whose highest degree of the variable used in the equation is 2 and has 2 roots, is called quadratic equation.

Here the quadratic equation of the path of Chase's ball is given by y = - 4x²+ 5x+ 7
To compare the height of both paths followed by the ball
we have to first calculate the height of the path of Chase's ball.
the path of Chase's ball is f(x)=-4x²+ 5x+ 7
The function will have the highest value when f'(x) will be 0.
f'(x)=-8x+5
f'(x)=0
⇒-8x+5=0
⇒-8x=-5
⇒x=5/8
at x=5/8, function value is
f(x)=-4x²+ 5x+ 7
=-4(5/8)²+ 5(5/8)+ 7
=-4(25/64)+(25/8)+7
=(-25/16)+25/8+7
=8.5625
There maximum value of f(x) is 8.5625.
The maximum height reached by Chase's ball will be 8.5625m.
From the graph of the path of Alonzo's ball, it is clear that
The maximum height reached by Alonzo's ball will be 9m.
As 8.5625m < 9m
Alonzo's baseball will reach greater height.

For 8% p-value cutoff , Melissa should use 92% confidence interval

A confidence interval calculated for a treatment effect measure shows the range in which the true treatment effect is likely to fall.

A smaller sample size or higher variability will result in a wider confidence interval with a larger margin of error. The interval width is also influenced by the level of confidence. If you want a higher level of certainty, the interval should be wider.

The width of the confidence interval and the size of the p value are related.

The narrower the interval, the smaller the p value. The confidence interval, on the other hand, provides useful information about the likely magnitude of the effect under consideration as well as the accuracy of the estimate.

Answer:4.25

Step-by-step explanation: because it is daddy

The solution of the equations 4x + 6y = 21 and 7x - 3y = 3 will be (1.5, 2.5).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equation is given below.

4x + 6y = 21            ...1

7x - 3y = 3              ...2

From equation 2, then we have

7x - 3y = 3

3y = 7x - 3

y = (7/3)x - 1

Put in equation 1, then we have

4x + 6[(7/3)x - 1] = 21

4x + 14x - 6 =  21

18x = 27

x = 3/2

x = 1.5

Then the value of the variable 'y' is calculated as,

y = (7/3)(3/2) - 1

y = 7/2 - 1

y = 3.5 - 1

y = 2.5

The solution of the equations 4x + 6y = 21 and 7x - 3y = 3 will be (1.5, 2.5).

Answer:

The runners will be in a straight line after 1/2 seconds.

To solve this problem, we can set the y-coordinates of each runner equal to each other and solve for t. The y-coordinate represents the lane number, and if the lane numbers are equal, the runners are on a straight line.

Jon: y = 1

Laura: y = 2

Ellis: y = 4

Jon: 3t = 1

Laura: 4t = 2

Ellis: 6t = 4

Solving these equations simultaneously, we find that t = 1/2 seconds. This means that after 1/2 seconds, the runners will be in a straight line.

Answer: the answers should be B and D

so basically, this is just simplifying

B is the correct answer because the numerator 12, when divided by 4 is 3, and the denominator 32, when also diving by 4, is eight. This makes the two fractions equivalent.

Same goes for D, for if you diving the numerator and denominator by 2, you get answer choice D

In mile there are 63360 inches.

The number of inches in a mile is equal to the number of inches in a foot times the number of feet in a mile

We multiply 528 by 12 and add one zero to the right of the result.

Use vertical form to perform the multiplication.

So. 12 × 5280=63360

  ∴ 5280/6336

  = 1056

The number of inches in a mile = 12 × 5280

We multiply 528 by 12 and add one zero to the right of the result.

Use vertical form to perform the multiplication:

  528 × 12 = 1056

1056 + 5280 = 6336

So, 12 × 5280 = 63360 miles

The slope of this line is -3/2

A perpendicular slope is the opposite reciprocal.  That means you flip it upside down and take the opposite sign.  Since this slope is negative, the perpendicular slope will be positive.  If I turn this fraction upside down it will be 2/3, so the perpendicular slope is 2/3.

For the equation of the line we need the slope (m) and the y intercept.  To find that we will use the point that goes through this line.

m = (2/3)

x  = -4      from the point given (-4, 6)

y = 6        from the point given (-4,6)

y = mx + b

6 = [tex]\frac{2}{3}[/tex] [tex](\frac{-4}{1})[/tex] + b

6 = [tex]\frac{-8}{3}[/tex] + b   Add [tex]\frac{8}{3}[/tex] to both sides

[tex]\frac{6}{1}[/tex] + [tex]\frac{8}{3}[/tex] = b

[tex]\frac{18}{3}[/tex] + [tex]\frac{8}{3}[/tex] = b

[tex]\frac{26}{3}[/tex]

y = [tex]\frac{2}{3}[/tex] x + [tex]\frac{26}{3}[/tex]

Parallel lines have the same slope.

m = [tex]\frac{-3}{2}[/tex]

x = -4   from the point (-4,6)

y = 6   from the point (-4,6)

y = mx + b

6 = [tex]\frac{-3}{2}[/tex][tex](\frac{-4}{1})[/tex] + b

6 = 6 + b  Subtract 6 from both sides

0 = b

y = [tex]\frac{-3}{2}[/tex] x

According to the given statement Liam is incorrect because average speed is 34.28 miles per hour.

The average scores of a body's speed over a duration of time is its average speed. Because a moving body's speed is not constant over time and fluctuates, the average speed formula is required.

The overall distance the thing travels in a given amount of time is its average speed. A scalar value symbolizes the average speed. It has no direction and therefore is indicated by the magnitude.

Distance covered in first three hours = 40 × 3 = 120 miles

Time taking to covered remaining 120 miles = 120/30

                                                                          = 4 hours

Total time = 4 hours + 3 hours = 7 hours

Total distance = 120 miles + 120 miles

                        = 240 miles

Average speed = total distance /  total time

Average speed = 240 miles / 7 hours = 34.28 miles per hour
