For the given triangles the length of the missing side x is 56in.

As given in the question,

Two triangles are given ,

Let the triangle with measurement 40in. and 35in. be A and another is B.

In triangle A,

Let missing angle be α

Sum of all the angles in the interior of a triangle is equal to 180°

51°+ 74° + α = 180°

⇒α = 55°

In triangle B.

Let missing angle be β,

74° + 55° + β = 180°

⇒β= 51°

By AAA both the triangles are similar.

Length of corresponding sides are in proportion.

40: x = 35 : 49

⇒x = ( 40×49)/35

⇒x= 56in.

Therefore, for the given triangles the length of the missing side x=56in.

Option D is the right choice.

It is discovered through the use of conditional probability that there is a 0.4 = 40% chance that it will stop working in less than 2 years.

Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.

Conditional Probability:
P (B / A) = P (A∩B) / P (A)

Here:

P(B / A) is the likelihood that event B will occur in the absence of event A.

P (A∩B) is the likelihood that both A and B will occur.

P(A) denotes the likelihood that A will occur.

As per the question:

Event A: Delivery was harmed.

Event B: Fails to function after less than two years.

P (A) = 0.1 due to the probability of being damaged during delivery being 0.1.

P (A∩B) = 0.04 because there is a 0.04 likelihood that it will be damaged during the delivery and stop working.

The likelihood under the condition is:

P (B / A) = P (A∩B) / P (A) = 0.04 / 0.1 = 0.4

0.4 = 40% chance that it will stop working in under two years.

Therefore, option D is correct.

Answer:

Step-by-step explanation:

3.4.m+2.4.m.m

4m(3+2m)

Answer:

Step-by-step explanation:

(a is in the file)

B. An add 3 inches to height would affect the surface area more than 3 inches to weight because if the same number was multiplied to 0.13 and 0.08… 0.13 would have the greater outcome.

c. a number more than 10 but less than 11 is 10.5

The height is 50 so plug those two numbers into the equation

10.5=0.08W+(0.13)50-1.03

10.5=0.08W+ 6.5-1.03

10.5=0.08W+5.47

Subtract 5.47 from both sides

5.3=0.08

Divide by 0.08 on both sides

= 62.87lbs in one possibility for the value of W

D. a number between 12 and 13 is 12.5

12.5= 0.08w+ 0.13H-1.03

Subtract 1.03 on both sides

11.47= 0.08w+ 0.13H

Divide 11.47 in 2 so that weight and height can be added up to equal 11.47 in the end

5.73=0.08   5.73=0.13

71.68=W    44.07=H

By using the concept of kinetic energy, it is obtained that

Kinetic energy of the  airplane when its velocity is 300 m/s is 20250 megajoule

What is Kinetic energy?

Kinetic energy is the energy possessed by the body by virtue of its motion

If m is the mass of the body and v is the velocity of the body, then kinetic energy is given by the formula

Kinetic energy = [tex]\frac{1}{2} \times m \times v^2[/tex]

Let the mass of the airplane be m kg

Velocity = 220 m/s

Kinetic energy = [tex]\frac{1}{2} \times m \times (220)^2[/tex]

By the problem,

[tex]\frac{1}{2} \times m \times (220)^2 = 10890\times 10^6[/tex]

[tex]m = \frac{10890\times 10^6\times 2}{220\times 220}[/tex]

m = [tex]0.45 \times 10^6[/tex] kg

Now,

Velocity = 300 m/s

Kinetic energy = [tex]\frac{1}{2} \times 0.45 \times 10^6 \times 300 \times 300[/tex]

                        = [tex]20250 \times 10^6[/tex] J

The plan that would give Genesis the lowest monthly payment is D. The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.

From the information, the home improvement project that totals $16,000, and Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years.

The simple interest earned will be:

= Principal × Rate × Time / 100

= (16000 × 8 × 3)/100

= $551.11

The compound interest will be:

A = P(1 + r/n)^nt

A = accumulated amount

P = amount deposited

r = rate

n = times of compound per year

t = years

This will be:

A = 16000(1 + 0.15/12)^(12×7)

A = $540.78

Answer:

x = 36

The measure of the exterior angle is 114°

The remote interior angles are 24° and 90°.

Step-by-step explanation:

The angle marked 3x + 6 is the exterior angle. The other two marked angles are called "remote interior angles"

The two remote interior angles added together equals the exterior angle.

3x+6 = 24° + 2x + 18

Combine like terms.

3x + 6 = 2x + 42

Subtract 2x from both sides.

x + 6 = 42

Subtract 6 from both sides.

x = 36

If required, use the x=36 to find the measure of the exterior angle.

3(36) + 6

= 108 + 6

= 114°

Or find the measures of the remote interior angles.

2(36) + 18

= 72 + 18

= 90°

The remote interior angles are 24° and 90°.

The shortest total length of fence this can be done with will be 440 m as the total area is 2000 m².

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter. In this instance, x represents the rectangle's length and y its width. The distance around an object is called the perimeter. For instance, the yard of your home is fenced in. The fence's length serves as the perimeter. Your fence is 200 feet long if the yard is 50 feet by 50 feet.

Here,

The area=2000 m²

xy=2000

x=2000/y

p=4x+2y

p=4*(2000/y)+2y

=8000/y+2y

p'=-8000/y²+2

-8000/y²+2=0

2y²-8000=0

y²-4000=

y²=4000

y= 20 m

p=8000/20+2*20

p=400+40=440 m

Given that the total area is 2000 m², the shortest total length of fence that can be used is 440 m.

What is a function rule?

The equation-based relationship between the dependent and independent variables is known as a function rule. In simple words, a function is an association between inputs in which each input is connected to precisely one output.

Given,  y = -5x + 2

when x= -2, y = (-5)* (-2) + 2 = 10 + 2 = 12, y = 12

when x= 0, y = (-5)* (0) + 2 = 0 + 2 = 2, y = 2

when x= 2, y = (-5)* (2) + 2 = -10 + 2 = -8, y = -8

when x= 4, y = (-5)* (4) + 2 = -20 + 2 = -18, y = -18

Because 750 people are going in a coach trip and each coaches can hold 50 people.

The culture starts out with 39 members.

Given that;

After 20 minutes and 40 minutes, a bacteria culture had an 800 and 1700 count, respectively.

To get exponential growth;

We can get growth with an exponential function,

F(t) = A₀[tex]e^k^t[/tex]

Here, k is the growth constant and A₀ is the initial amount of bacteria.

Let;

800 = A₀[tex]e^2^0^k[/tex]  → (I)

1700 = A₀[tex]e^4^0^k[/tex] → (II)

From (I) and (II);

1700 / 800 =  A₀[tex]e^4^0^k[/tex] / A₀[tex]e^2^0^k[/tex]

17/8 = [tex]e^2^0^k[/tex]

For the above equation take the natural log on both sides;

ln(17/8) = ln [tex]e^2^0^k[/tex]

ln(17/8) = 20k

k = ln(17/8) / 20

To get the initial size of the culture;

From (I),

800 = A₀[tex]e^2^0^k[/tex]

800 = A₀e⁰°⁰³⁷⁶ ˣ ²⁰

A₀ = 800 / 20.76

A₀ = 38.53 ≅ 39

Therefore, the initial size of the culture is 39.

The length CT of the line segment is 38 units

From the question, we have the following parameters

CJ = 9x + 1

JT = 2x + 15

Also, we understand that:

Point J is the midpoint of segment CT.

This means that

CJ = CT

So, we have

9x + 1 = 2x + 15

Evaluate the like terms

7x = 14

So, we have

x = 2

Length CT is calculated as

CT = 9x + 1 + 2x + 15

The maximum number of people the lift can safely carry is 8 people.

Given that, the average mass of a man is 84 kg and of a woman is 70 kg.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Now, average = (84+72)/2

= 156/2

Next we calculate the net advantage in year 5

= net advantage in year 0 + cost saving in 5 years

= - $ 55,750 + ($ 26,750 - $ 11,750) * 5
