What is the measure of 1 in the trapezoid?



110°
55°
165°
85°

Answer:

2 minutes 40 sec

Step-by-step explanation:

Recall that distance = rate times time.

Thus, time = distance / rate.

Here,

time = 280 ft / (1.75 ft/sec) = 160 sec, or 2 minutes 40 sec

To calculate the time it takes to travel 280 feet on a moving walkway at an airport moving at a pace of 1.75 feet per second, we use the formula time = distance/pace. This equates to approximately 160 seconds.

The question is asking about the time it takes to transport someone along a distance of 280 feet by a moving walkway in an airport, given that the pace of the walkway is 1.75 feet per second. To answer this, you use the formula of time = distance/pace. So we have time = 280 feet / 1.75 feet per second. This calculation will give you the answer in seconds. When you do this calculation, you will find that it takes approximately 160 seconds to cover that distance on the moving walkway.

Answer:

4X + 30 = TOTAL AMOUNT OF MONEY

Step-by-step explanation:

All of them bought a ride ticket (that explains the 4x)

3 of them also bought a game pass thet costs $10 each. That explains the 30

going deeper: If the total amount of money was $70

The tickets would've costed $10 each.

Look:

4x + $30 = $70

4x = 70 - 30

4x = 40

x = 40/4

x =$10

1 feet is 12 inches.

We have 5 feet and 6 inches. First, let's convert the feet to inches. 5 times 12 is 60, so 5 feet is 60 inches.

Now add 60 inches to the 6 inches that we didn't mention. 60 plus 6 is 66. Thus, 5 feet and 6 inches is 66 inches.

Answer:

The answer is 66

Step-by-step explanation: 1 foot is 12 inches so you do 12 times 5 and get 60 and then add the next 6 inches... :)

Problem 1

a) y = 8 and c) x = 2 are perpendicular lines to one another. The first is horizontal and the second is vertical.

The other two lines are not perpendicular because their slopes (1/8 and 8) do not multiply to -1. This rule only applies to lines that are neither horizontal nor vertical.

Answers: A and C.

============================================

Problem 2

Equations b) y = (-1/2)x - 4 and c) y-4 = 2(x+3) are perpendicular. Equation B has a slope of -1/2, while equation C has a slope of 2. Those two values multiply to -1. One slope is the negative reciprocal of the other. It might help to think of 2 as 2/1.

The other two equations are not perpendicular to each other, nor are they perpendicular to B or C. Equation A has a slope of 0. Equation D has a slope of -2.

Answer:

m∠A=m∠D=60°, m∠B=m∠C=120°

Step-by-step explanation:

Consider isosceles trapezoid ABCD with midsegment MN. Draw two trapezoid heights BF and CE. Then quadrilateral FBCE is rectangle and EF=BC=17 units.

By the trapezoid midsegment theorem,

[tex]MN=\dfrac{AD+BC}{2},\\ \\30=\dfrac{AD+17}{2},\\ \\60=AD+17,\\ \\AD=60-17=43\ units.[/tex]

Segments FA and ED are equal to [tex]\dfrac{43-17}{2}=13\ units.[/tex]

In right triangle ABF, the hypotenuse AB is twice greater than the leg FA, then m∠FBA=30°.

m∠B=m∠FBA+m∠CBF=30°+90°=120°.

In isosceles trapezoid

m∠B=m∠C=120°,

m∠A=m∠D and m∠A=180°-m∠B=180°-120°=60°=m∠D.

In a trapezoid with equal bases and a midsegment, the angle measures of the trapezoid can be determined using the properties of the figure. In this case, the angle measures are 90 degrees for each angle.

In a trapezoid ABCD, the midsegment MN is parallel to the bases AB and CD, and its length is equal to the average of the lengths of the bases. Given that AB = 26, CD = 26, and MN = 30, we can set up the equation: MN = (AB + CD) / 2. Substituting the given values, we get 30 = (26 + 26) / 2. Solving for the angle measures, we can use the fact that the opposite angles in a trapezoid are congruent. So, m∠A = m∠C and m∠B = m∠D. Since the sum of the interior angles of a trapezoid is always 360 degrees, we can use the equation: m∠A + m∠B + m∠C + m∠D = 360. Substituting the angle measures we found, we get 2(m∠A) + 2(m∠B) = 360. Solving for the angle measures, we get m∠A = m∠C = 90 degrees and m∠B = m∠D = 90 degrees.

Answer:

It is NOT a right triangle.

Step-by-step explanation:

You must figure out the slopes of the segments of the triangle to see if it is a right triangle. If they are perpendicular (meaning the slopes are negative reciprocals of each other), they form a right angle, making it a right triangle.

[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex] This formula finds slope using two points.

Let's figure out the slope of JK.

(-1-1)/(-5-0) = m

Simplify.

-2/-5 = m

A negative divided by a negative makes a positive.

2/5 = m

Now LK.

(-5-1)/(2-0) = m

Simplify.

-6/2 = m

Divide.

-3/1 = m

Now JL.

(-1+5)/(-5-2) = m

Simplify.

4/-3 = m

None of these slopes are negative reciprocals of each other, thus deeming it not a right triangle.

Jeff's net pay is $1,065.70 per week.

To calculate Jeff Jones's net pay, we need to consider several deductions from his gross pay.

1. Gross Pay: Jeff earns $1,200 per week.

2. Social Security Deduction: Social Security tax is 6.2% of the first $118,500 of earnings. Jeff's earnings are below this threshold, so his Social Security deduction is 6.2% of his gross pay.

Social Security deduction = 6.2% of $1,200 = 0.062 * $1,200 = $74.40

3. Medicare Deduction: Medicare tax is 1.45% of all earnings.

  Medicare deduction = 1.45% of $1,200 = 0.0145 * $1,200 = $17.40

4. Health Insurance Deduction: $42.50 is deducted for health insurance.

5. Total Deductions: Add up all deductions.

Total deductions = Social Security deduction + Medicare deduction + Health insurance deduction

= $74.40 + $17.40 + $42.50

= $134.30

6. Net Pay: Subtract total deductions from gross pay.

Net pay = Gross pay - Total deductions

= $1,200 - $134.30

= $1,065.70

Therefore, Jeff's net pay is $1,065.70 per week.

Answer:

Option B is correct.

Value of cos(a+B) is,  [tex]\frac{16}{65}[/tex]

Step-by-step explanation:

Using the formula:

[tex]\cos(a+B) = \cos a \cos B -\sin a \sin B[/tex]

Given the values:

[tex]\cos a = \frac{3}{5}[/tex] and [tex]\sin B = \frac{5}{13}[/tex]

Using trigonometric identity:

[tex]\sin^2 \theta + \cos^2 \theta =1[/tex]

or

[tex]\sin \theta = \sqrt{1-\cos^2 \theta}[/tex]

or

[tex]\cos \theta = \sqrt{1-\sin^2 \theta}[/tex]

Find the value of sin a and cos B;

Using trigonometric identity:

[tex]\sin a = \sqrt{1-\cos^2 a}[/tex]

[tex]\sin a = \sqrt{1-(\frac{3}{5})^2}[/tex] = [tex]\sqrt{1-\frac{9}{25}} = \sqrt{\frac{25-9}{25}}=\sqrt{\frac{16}{25} } =\frac{4}{5}[/tex]

Similarly;

[tex]\cos B = \sqrt{1-\sin^2 B}[/tex]

[tex]\cos B = \sqrt{1-(\frac{5}{13})^2}[/tex] = [tex]\sqrt{1-\frac{25}{169}} = \sqrt{\frac{169-25}{169}}=\sqrt{\frac{144}{169} } =\frac{12}{13}[/tex]

Substitute these given values equation [1] we have;

[tex]\cos(a+B) =\frac{3}{5} \cdot \frac{12}{13}-\frac{4}{5} \cdot \frac{5}{13}[/tex]

[tex]\cos(a+B) =\frac{36}{65}-\frac{20}{65}[/tex]

then;

[tex]\cos(a+B) =\frac{36-20}{65}=\frac{16}{65}[/tex]

Since, the angles a and B are in first quadrant angles therefore the value of cos(a+B) is, [tex]\frac{16}{65}[/tex]

To find cos(a + B), use the formula cos(a + B) = cos(a)cos(B) - sin(a)sin(B). Substitute the given values of cos(a) = 3/5 and sin(B) = 5/13, and solve for cos(B) using the Pythagorean identity. Then substitute all the values into the formula and simplify to find cos(a + B) = 16/65.

To find cos(a + B), we can use the formula:

cos(a + B) = cos(a)cos(B) - sin(a)sin(B)

Given that cos(a) = 3/5 and sin(B) = 5/13, we can substitute these values into the formula:

cos(a + B) = (3/5)(cos(B)) - (sin(a))(5/13)

To find cos(B), we can use the Pythagorean identity:

cos²(B) + sin²(B) = 1

Substituting the given value of sin(B), we can solve for cos(B):

cos(B) = √(1 - (5/13)²)

Now we can substitute the values of cos(a), sin(B), and cos(B) into the formula for cos(a + B):

cos(a + B) = (3/5)(√(1 - (5/13)²))) - (5/13)(5/13)

Simplifying this expression gives us the final answer: cos(a + B) = 16/65.

C) ∠6 and ∠7

Step-by-step explanation:

We have been given that lines a and b are parallel. We are asked to find the angle on line b that will be congruent to angle 3.

We can see that angle 3 is under the line a and on the left side of transversal.

We know that the corresponding angles and alternate interior angles formed by two parallel lines are equal.

We can see that angle 7 corresponds to angle 3 and angle 6 is alternate interior angle of angle 3.

Therefore, angle 7 and angle 6 will be congruent with angle 3 and option C is the correct choice.

Answer:

(- 3, 0), (2 + [tex]\sqrt{2}[/tex], 0), (2 - [tex]\sqrt{2}[/tex], 0)

Step-by-step explanation:

rearrange the equation equating to zero

x³ - x² - 10x + 6 = 0

note that when x = - 3

(- 3)³ - (- 3)² - 10(- 3) + 6 = - 27 - 9 + 30 + 6 = 0, hence

x = - 3 is a root and (x + 3) is a factor of the polynomial

dividing x³ - x² - 10x + 6 ÷ (x + 3) gives

(x + 3)(x² - 4x + 2) = 0

solve x² - 4x + 2 = 0 using the quadratic formula

with a = 1, b= - 4 and c = 2

x = (4 ± [tex]\sqrt{16-(4(1)(2)}[/tex])/ 2

  = (4 ± [tex]\sqrt{8}[/tex]) / 2

  = (4 ± 2[tex]\sqrt{2}[/tex]) / 2

  = 2 ±[tex]\sqrt{2}[/tex], hence

x = 2 + [tex]\sqrt{2}[/tex], x = 2 - [tex]\sqrt{2}[/tex]

intersect at (- 3, 0), (2 +[tex]\sqrt{2}[/tex], 0), (2 - [tex]\sqrt{2}[/tex], 0)

Answer: [tex]\bold{x=-3,\quad x=2+\sqrt{2}, \quad x=2-\sqrt{2} }}[/tex]

Step-by-step explanation:

First, move all terms to one side with zero on the other side so the Zero Product Property can be applied:

x³ - x² - 10x + 6 = 0    Possible rational roots are: ±{1, 2, 3, 6}

Use synthetic division to find one of the roots.  Let's try x = -3

-3 |  1    -1    -10    6

   |  ↓   -3    12    -6

      1    -4     2     0  ← remainder is zero, so x = -3 is a root/intercept

Next, evaluate the reduced polynomial x² - 4x + 2 = 0

This can not be factored so use the quadratic formula to find the remaining roots/intercepts: [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

a = 1, b = -4, c = 2

[tex]x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(2)}}{2(1)}[/tex]

 [tex]=\dfrac{4\pm\sqrt{16-8}}{2}[/tex]

 [tex]=\dfrac{4\pm\sqrt{8}}{2}[/tex]

 [tex]=\dfrac{4\pm2\sqrt{2}}{2}[/tex]

 [tex]=2\pm\sqrt{2}[/tex]

[tex]x=2+\sqrt{2}\qquad x=2-\sqrt{2}[/tex]

Intercepts are [tex]x=-3,\quad x=2+\sqrt{2}, \quad x=2-\sqrt{2}}[/tex]
