Answer:

2 2/5 or 12/5 (if u want it in improper fraction) but both works!

Step-by-step explanation:

Answer: 2 2/5

Step-by-step explanation: 9/5 has to have the same denominator as 6/10 so it becomes 18/10 and subtracting a negative number makes it addition so 18/10 + 6/10 is 24/10 and you simplify it to become 2 2/5

Answer:

Because the triangle is isosceles, the base angles are congruent, meaning that the angles that are not right angles are x and x. Since the sum of angles in a triangle is 180°, we can write:

90 + x + x = 180

x + x = 90

2x = 90

x = 45°

Answer:

45 degrees

Step-by-step explanation:

This triangle is "isosceles..." two legs are equal.  Thus, the triangle has two 45 degree angles.  The indicated angle is 45 degreees.

Answer:

The selling price of the bag is $22.5

Step-by-step explanation:

Buying Price = $25,

Selling Price = ?

Since they sold it at a loss of 10%,

So, they sold it for a price 10% less than the buying price,

or at 90% or 0.9 of the buying price,

so,

Selling Price = (0.9)(25) = $22.5

The % error between the experimental and simulation results is determined to be an average of 7.17%, with a standard deviation of 4.15%. This indicates the level of deviation and variability between the two sets of data.

To determine the % error and standard deviation between the experimental and simulation results, we can follow these steps:

1. Calculate the absolute error for each data point by subtracting the simulation deflection from the experimental deflection.

  Absolute Error = Experimental deflection - Simulation deflection

2. Calculate the % error for each data point by dividing the absolute error by the experimental deflection and multiplying by 100.

  % Error = (Absolute Error / Experimental deflection) * 100

3. Calculate the average % error by taking the mean of all the individual % errors.

4. Calculate the standard deviation of the % errors to measure the variability between the experimental and simulation results.

Let's calculate the % error and standard deviation using the provided data:

Load (KN)   | Experimental deflection (mm) | Simulation deflection (mm)

------------------------------------------------------------------------------------------------------

0.90               | 7.5                                          | 6.4

0.85               | 15.7                                         | 13.5

0.80               | 35.6                                        | 32.9

0.75               | 65.5                                        | 63.0

0.70               | 95.25                                      | 91.5

1. Calculate the absolute error for each data point:

  Absolute Error = Experimental deflection - Simulation deflection

2. Calculate the % error for each data point:

  % Error = (Absolute Error / Experimental deflection) * 100

3. Calculate the average % error:

  Average % Error = (Sum of % errors) / Number of data points

4. Calculate the standard deviation of the % errors:

  Standard Deviation = sqrt((Sum of (each % error - Average % Error)^2) / (Number of data points))

After performing the calculations, we find the % error and standard deviation as follows:

Load (KN)   |    % Error       |

----------------------------------

0.90            |    14.7%          |

0.85            |     7.64%         |

0.80            |     7.9%           |

0.75             |     3.8%           |

0.70             |     3.77%         |

Average % Error: 7.17%

Standard Deviation: 4.15%

Therefore, the average % error between the experimental and simulation results is 7.17%, and the standard deviation of the % errors is 4.15%.

Answer:

(A) Perimeter

Step-by-step explanation:

Given:

In 1933, Wiley Post flew around the world in 7 days, 18 hours. Wiley's trip would best

be described as flying around the

of the earth.

a. perimeter

b. area

c. volume

d. diameter

Solution:

Let's first define each answer choices:

Perimeter - the distance around the object.

Area - total space taken up by a flat (2-D) surface or shape of an object

Volume- amount of three-dimensional space occupied by an object or a closed surface.

Diameter - a straight line that runs from one side of a figure and passes through the center

From what we define above I would say Perimeter.

Because Earth is round as well as Wiley Post flying around earth. Hence, the best answer is (A) Perimeter - the distance around the object.

Answer:

Step-by-step explanation:

9) PQR Is an isosceles triangle

=> ∠PRQ = (180° - x)/2

PRS is an isosceles right triangle

=> ∠PRS = 45°

Have: ∠PRS + ∠PRQ = 115°

=> \(\frac{180-x}{2}+45=115 \\\)

=> 180 - x = (115 - 45).2 = 140

<=> x = 180 - 140 = 40

10) ABD is an isosceles right triangle => ∠ABD = 45°

BCD is an equilateral triangle => ∠CBD = 60°

have: x = ∠ABD + ∠CBD = 45° + 60° = 105°

11) have: x = y (2)

PQT is an isosceles triangle => ∠PQT = 180 - 70.2 = 40

QTS   is an isosceles triangle => ∠TQS = 180 -2x

QRS   is an isosceles triangle => ∠RSQ = y

have: 40 + 180 - 2x + y = 180 => 2x - y = 40 (1)

(1)(2) => \(\left \{ {{y=x} \atop {2x-y=40}} \right.\\\\=> \left \{ {{x=40} \atop {y=40}} \right.\)

=> x + y = 80

12) EFJ Is an equilateral  triangle => ∠FJE = 60

∠FJE is the outer angle of the triangle FHJ but FHJ is an isosceles triangle

=> 60 = 2.∠JHF => ∠JHF = 30°

∠JHF is the outer angle of the triangle FHG

=> 30° = 2x

<=> x = 15°

Answer:

15 + _ = -15

15 + 15 = _

- 30 = _

- 30 is the answer.

Step-by-step explanation:

The measure of ∡KJR is 69°.

What is the sum of two supplementary angles?
Two angles are referred to as supplementary angles if their combined value is 180°. A straight angle is created when supplementary angles are combined (180°).
In other words, ∡A and ∡B are supplementary if ∡A plus ∡B equals 180°. Angles A and B are described as "supplements" of one another in this context.
In math, A° + B° = 180°.

Given, m∡RJI = 12x - 3, m∡KJR = 6x - 5, m∡KJI = 172°
As seen from diagram, m∡RJI + m∡KJR = m∡KJI
⇒ (12x-3)+(6x-50) = 172° ⇒ 18x - 53 = 172° ⇒ x = ([172 + 53]/18)° = 12.5°
Therefore, the value of x = 12.5°
Thus, m∡KJR = 6x - 5 = (6*12.5) - 5 = 69°

Answer:

4=x

Step-by-step explanation:

-3(x-2)=2(x-7)

Distribute -3 and 2.

-3x+6=2x-14

Add 3x to both sides of the equation.

6=5x-14

Add 14 to both sides of the equation.

20=5x

Divide 5 from both sides of the equation.

4=x

Hope this helps :)

Answer:

x=5

Step-by-step explanation:

Our equation is

-3(x-2)=2(x-7)

First we will distribute -3 and 2, because in math when we have a number being multiplied into parenthesis we multiply both things inside of it

Our equation is now

-3x+6=2x-14

Next we subtract 6 from both sides because we want x to be on only one side

-3x=2x-20

Next we subtract 2x from both sides because we want x to equal something exactly

-5x=-20

Now we divide -5 from both sides because we only want x

x=5

The winner of the election got 26320 votes.

Let's first find the total number of votes cast in the election. We know that 2/3 fraction of the electors voted for the first candidate and 1/4 of the electors voted for the second candidate. Therefore, the remaining 1/12 of the electors voted for the third candidate. So, we have:

2/3 + 1/4 + 1/12 = 8/12 + 3/12 + 1/12 = 12/12 = 1

This means that all the electors voted, and the total number of votes cast is equal to the total number of electors.

Now, let's find the number of votes the third candidate got, which is 1/12 of the total number of votes. We know that this is equal to 3290. So, we have

1/12 x Total Number of Votes = 3290

Multiplying both sides by 12, we get:

Total Number of Votes = 3290 x 12 = 39480

Now, we can find the number of votes the first candidate got, which is 2/3 of the total number of votes. We have:

2/3 x Total Number of Votes = 2/3 x 39480 = 26320 votes

Answer: The differential equations is

y3 3x3logx = 8x3.

Step-by-step explanation:

break the given original- value problem. The DE is homogeneous. xy2dy/ dx = y3- x3; y( 1) = 2.

result

Given a homogenous discriminational equation, xy2 dy/ dx = y3- x3

xy2dy/ dx = y3- x3

dy/ dx = ( y3- x3)/ xy2

dy/ dx = (( y/ x) 3- 1)/( y2/ x2)---( 1)

Put y/ x = v ⇒ y = xv

separatew.r.t x

dy/ dx = x.dv/ dx v

Equation( 1) becomes,

⇒ dv/ dx v = ( v3- 1)/ v2

⇒ dv/ dx = (( v3- 1)/ v2)- v

⇒ dv/ dx = ( v3- 1- v3)/ v2

v2. dv = -1/x.dx

Integrate on both sides, we get

∫ v2. dv = ∫- 1/x.dx

v3/ 3 = - logx C

1/3( y3/ x3)) log x = C( 2)

Now, given that y( 1) = 2

Substituting y = 2 and x = 1 in equation( 2)

(1/3) ×(23/13)) log 1 = C

C = 8/3

From equation( 2), we get

⇒( y3/ 3x3) logx = 8/3

thus, the needed differential equation is y3 3x3logx = 8x3.

Step-by-step explanation:

Jerry's cost of going to college is $29,000.

Jerry's cost of going to college is $29,000. The cost of going to college is a major concern for many students. As a result, making a sound financial plan is essential when considering post-secondary education. It is important to weigh the costs of going to college against the benefits of obtaining a degree. Jerry has to make a choice between going to college or working in a store. If he chooses to go to college, he will have to spend $15,000 on tuition, $12,000 on room and board, and $2,000 on books. Therefore, his total cost of attending college is

$29,000 ($15,000 + $12,000 + $2,000).

If he decides not to go to college, Jerry will earn $27,000 by working in a store and spend $10,000 on room and board. By adding up his earnings and expenses, he will have a total of

$17,000 ($27,000 - $10,000)

In this case, it is less expensive for Jerry not to go to college. He will have $12,000 more in his pocket ($17,000 - $29,000) if he does not go to college. Therefore, Jerry's cost of going to college is $29,000.
