How do you find the measure of angle A?
Answer:
m∠A = 18
Step-by-step explanation:
Formula:
the sum of the interior angles of a triangle is 180.
____________________
According to the formula :
[tex]m\angle A\ +\ m\angle B\ +\ m\angle C=180[/tex]
⇔ x - 22 + 3x + 19 + x - 17 = 180
⇔ 5x + (19 - 17 - 22) = 180
⇔ 5x + (2 - 22) = 180
⇔ 5x - 20 = 180
⇔ 5x = 180 + 20
⇔ 5x = 200
[tex]\Leftrightarrow x = \frac{200}{5} \\\Leftrightarrow x = 40[/tex]
Conclusion:
m∠A = x - 22 = 40 - 22 = 18

A company sells cocoa powder in a cylindrical container that is 5 inches long with a circular base of diameter 4 inches. The company is planning to sell a family-size product that will use similar packaging scaled by a factor of 2.
The circumference of the original container is (62.8, 15.7, 12.57, 6.28)
inches. This is (18.84, 9.42, 37.68, 12.57)
inches less than the circumference of the new container.
The circumference of the original container is 12.57 inches.
The cirucmference of the original container is 12.57 inches less than the circumference of the new container.
What is the circumference of the cylinder?The circumference of a cylinder is the distance round the cylinder. It is the perimeter of the cylinder.
The circumference of a cylinder = πD
Where:
π = 22/7D = diameterThe circumference of the original container = 22/7 x 4 = 12.57 inches
The circumference of the family sized container 12.57 x 2 = 25.14 inches
Difference in the circumference = 25.14 - 12.57 = 12.57 inches

Applying the inscribed angle theorem, the measure of ∠BDA is: A. 83°.
What is the Inscribed Angle Theorem?When an angle is inscribed in a circle, the measure of the angle equals half the measure of the intercepted arc, according to the inscribed angle theorem.
Given the following:
m(BFA) = 166° [intercepted arc]m∠BDA = ? [inscribed angle]Applying the inscribed angle theorem, we have:
m∠BDA = 1/2(166)
m∠BDA = 83°
Thus, applying the inscribed angle theorem, the measure of ∠BDA is: 83°.

Find the median of the data.
24,74,61,29,38,27,68,54
Answer:
The median is 46
Step-by-step explanation:
To find the median, you must first order the numbers, from left to right, lowest to highest:
24, 27, 29, 38, 54, 61, 68, 74
Next, we have to find the number in the middle. We can do this by counting inwards one and crossing out each of the lowest and highest each time we get closer to the middle/center.
24, 27, 29, 38, 54, 61, 68, 74
, 27, 29, 38, 54, 61, 68,
, , 29, 38, 54, 61, ,
, , , 38, 54, , ,
Now, if there is no exact middle, we would add them add divide by 2. If there was an exact middle, that would be the answer. But there isn't.
38 + 54 = 92
92 / 2 = 46
The median is 46

Ramesh replaced all his 100-watt bulbs, a total of 8 with LED of 8 watts. If he uses bulbs for 8 hours per day, how much cost he will save per month if ` 5.70 per kWh is charged?
$1006.85 would be saved per month if the 8 watts LED replaced the 100 watts bulbs.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Amount of energy for the 100 watt bulb = 8 * 100 watt * 8 hr * 30 days =192000 Wh = 192 kWh
Amount of energy for the 8 watt bulb = 8 * 8 watt * 8 hr * 30 days = 15360 Wh = 15.36 kWh
The cost saved in a month = $5.7 * (192 - 15.36) = $1006.85
$1006.85 would be saved per month if the 8 watts LED replaced the 100 watts bulbs.

anyone know the answer??
Answer:
the second option
Step-by-step explanation:
in ax²+bx+c = 0:
[tex]x = \frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]
subtract both sides by 6 to get to this form, as the right side will be left with 0
6x² + 8x - 6 = 0
here, the coefficient for x² (a) is 6, the coefficient for x (b) is 8, and the remaining number added on (c) is -6
plugging our numbers into the formula, we get
[tex]x = \frac{-8+-\sqrt{(-8)^2-4(6)(-6)} }{2(6)}\\= \frac{-8+-\sqrt{64-(-144)} }{12} \\= \frac{-8+-\sqrt{208} }{12} \\ = \frac{-8+\sqrt{208} }{12} or \frac{-8-\sqrt{208} }{12}\\= 0.53518375848 or -1.86851709182\\= approximately -1.87, 0.54[/tex]

We have,
The polygon has the following sides:

The coordinates for each point are:
L = (1, 4)
P = (-1, -2)
N = (2, 0)
M = (4, 0)
The perimeter of the polygons.

Using the distance formula for the distance between two points (a, b) and (c, d):
Distance = √((c - a)² + (d - b)²)
Let's calculate the distances between the points:
LP:
Distance(LP)
= √((-1 - 1)² + (-2 - 4)²)
= √((-2)² + (-6)²)
= √(4 + 36)
= √40
= 6.32
PN:
Distance(PN)
= √((2 - (-1))² + (0 - (-2))²)
= √((2 + 1)² + (0 + 2)²)
= √(3² + 2²)
= √(9 + 4)
= √13
≈ 3.61
NM:
Distance(NM)
= √((4 - 2)² + (0 - 0)²)
= √(2² + 0²)
= √4
= 2
ML:
Distance(ML)
= √((4 - 1)² + (0 - 4)²)
= √((4 - 1)² + (-4)²)
= √(3² + 16)
= √(9 + 16)
= √25
= 5
Now,
Perimeter = LP + PN + NM + ML
Perimeter ≈ 6.32 + 3.61 + 2 + 5 ≈ 16.93
Thus,
The perimeter of the polygon is approximately 17.93 units.

Answer:
-20/25
Step-by-step explanation:
To change a fraction to one with a different denominator, common factors can be removed or added to numerator and denominator as required.
__
-48/60 can be reduced to lowest terms by removing the common factor of 12. It can be made to have a denominator of 25 by adding a common factor of 5.
[tex]-\dfrac{48}{60}=-\dfrac{4\cdot12}{5\cdot12}=-\dfrac{4}{5}\\\\=-\dfrac{4\cdot5}{5\cdot5}=\boxed{-\dfrac{20}{25}}[/tex]

Alternatively, the numerator of the desired fraction can be found by multiplying the given fraction by the desired denominator.
numerator = 25×(-48/60) = -1200/60 = -20

A retailer agreed to take 5000 ball point pen. However he found that 12 persent are faulty. What was the percentage decrement
Answer:
88%
Step-by-step explanation:
The correct answer is 88% because 12% of the pens are defective.
As a result, 12% ÷ 5000 = 12 ÷ 100 x 5000
= 600
There are 600 defective pens.
The pens that are left are 5000 - 600 = 4400.
4400 pens are in good working order.
This means that 88 percent = 4400 ÷ 5000 x 100
