Answer:

ans: x= 1/(a-b)

Step-by-step explanation:

given equation is

ax = bx + 1

to isolate x , take bx to left side

or,

subtract bx on both sides , I.e

ax - bx = 1

x( a- b) = 1

x = 1/(a- b)

Answer:

The distance to the top of the balloon is approximately 33.977 meters

Step-by-step explanation:

The (horizontal) distance from the hot air balloon from the observer, l = 30 m

The angle of elevation to the top of the balloon, θ = 28°

With the balloon standing upright, the distance to the top of the balloon, d, the height of the balloon, h and the horizontal distance to the balloon, l, form a right triangle, where;

d = The hypotenuse side

l = The leg adjacent to the reference (given) angle,

h = The leg opposite to the given angle, θ

By trigonometric ratios, we have;

[tex]cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

From which we get;

[tex]cos\angle \theta = \dfrac{l}{d}[/tex]

[tex]cos(28^{\circ}) = \dfrac{30 \ m}{d}[/tex]

[tex]d = \dfrac{30 \ m}{cos(28^{\circ}) } \approx 33.977 \, m[/tex]

The distance to the top of the balloon, d ≈ 33.977 m

2.45 N

weight = mass x 9.8 m/s^2

Answer:

Here,

Mass ( m ) = 250g = (250/1000) kg =0.25 kg

g =9.8 m/s^2

Weight ( W ) = ?

We know that,

Weight ( W ) = m*g [Where g is acceleration due to gravity]

                   = (0.25*9.8) N

                    = 2.45 N

Answer: Question 1: A. 48 would the answer

Answer: Question 2: C. 48 would be the answer

Hope this help...

Have a great day.

Answer:

C ) 48

Step-by-step explanation:

To begin, you have to figure out which angles correspond on the two triangles.

So here are the angles that correspond:

U = N

T = M

S = L

So, ST would be similar to LM so 32 and 8 will be similar.

And UT will be similar to NM so the missing length and 12 are similar.

To begin, find out the scale factor by dividing 32 by 8 to get 4.

Then, multiply 12 by 4 to get 48 for the missing length.

Answer:

1.2803

Step-by-step explanation:

According to the Question,

Therefore, We have Average Gain(ц) = 0.8%

Standard deviation(σ) = 0.7%

Number of Companies(n) = 20

[tex]X_{i}[/tex] = (σ² × n) / ц  ⇒  (0.7²×20) / (0.8*10) = 1.2803

Answer:

the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

Here's how to calculate the mean absolute deviation.

Step 1.Calculate the mean.

Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

Step 3: Add those deviations together.

Step 4: Divide the sum by the number of data points.

Following these steps in the example below is probably the best way to learn about mean absolute deviation, but here is a more formal way to write the steps in a formula:

\text{MAD}=\dfrac{\sum{\lvert x_i-\bar{x} \rvert}}{n}MAD= ∑∣ xi -x /n

start text, M, A, D, end text, equals, start fraction, sum, open vertical bar, x, start subscript, i, end subscript, minus, x, with, \bar, on top, close vertical bar, divided by, n, end fraction

Example

Erica enjoys posting pictures of her cat online. Here's how many "likes" the past 666 pictures each received:

10, 15, 15, 17, 18, 21

Find the mean absolute deviation.

Step 1: Calculate the mean

The sum of the data is 96 total "likes" and there are 6 pictures.

\text{mean}=\dfrac{96}{6}=16

mean= 96/6=16

start text, m, e, a, n, end text, equals, start fraction, 96, divided by, 6, end fraction, equals, 16

The mean is 16

Step 2: Calculate the distance between each data point and the mean.

Data point Distance from mean

10 |10-16|=6

15 |15-16|=1

15 |15-16|=1

17 |17-16|=1

18 |18-16|=2

21 |21-16|=5

Step 3: Add the distances together.

6+1+1+1+2+5=16

Step 4: Divide the sum by the number of data points.

\text{MAD}=\dfrac{16}{6}\approx2.67MAD=

MAD=16/6 =2.67 Likes

On average, each picture was about 333 likes away from the mean.

Answer:

-0.5, -0.4,-0.3,-0.2,-0.1 and 0.1

Step-by-step explanation:

So,

[tex]\frac{-2}{3} =-0.6\\\frac{1}{2} =0.5[/tex]

Now,

Rational numbers between -2/3 and 1/2 will be -0.5, -0.4,-0.3,-0.2,-0.1 and 0.1

Volume of a rectangular prism=L×B×H

since the area is already given to you as 27/5units²...

volume=(27/5)×(5/2)

= 13.5 units³

Answer:- 1/2

Step-by-step explanation:

Answer:

p=1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

Multiply each side by 5 to clear the fractions

5(2/5 + p) = 5(4/5 + 3/5p)

2 +5p = 4 + 3p

Subtract 3p from each side

2+5p-3p = 4+3p-3p

2+2p = 4

Subtract 2 from each side

2+2p -2 = 4-2

2p =2

Divide by 2

2p/2 = 2/2

p=1

Answer:

[tex]x=65[/tex]

Step-by-step explanation:

Area of a triangle is always 180 degrees...

In this triangle we have two values given, lets make an equation & solve it:

[tex]x+68+47=180[/tex]

[tex]x+115=180[/tex]

[tex]x=180-115[/tex]

[tex]x=65[/tex]

To check if you have the right answer, add all the angles to get 180:

Answer:

11, 7, 44

Step-by-step explanation:

a+b+c = 62

a-4 = b

c = 4×a

I think you meant "diminished by four", right ?

=>

a + a-4 + 4×a = 62

6×a - 4 = 62

6×a = 66

a = 11

=>

b = 11 - 4 = 7

c = 4×11 = 44

Answer:

the length of the cloth remaining is 457.52 cm

Step-by-step explanation:

Given;

original length of the cloth, L₀ = 674.95 cm

final length of the cloth, L₁ = 217.43 cm

The length of the cloth remaining is calculated as follows;

ΔL = L₀ - L₁

ΔL =  674.95 cm - 217.43 cm

ΔL = 457.52 cm

Therefore, the length of the cloth remaining is 457.52 cm

"Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides."

Given,

Area of the first two walls is [tex]2*25*12[/tex] = 600 square feet

Area of the second two walls is [tex]2*20*12[/tex] = 480 square feet

Total area of the room is = 480+600 = 1080 square feet

The paint required for 1 feet is = 1/300

So, the paint required for 1080 feet is = 1080/300 =3.6

Given:

The area of a flower garden is 60 m².

One third of it was used for growing roses and the remaining area was divided into two equal parts.

To find:

The area of each remaining part.

Solution:

It is given that the area of a flower garden is 60 m² and one third of it was used for growing roses. So, the remaining part is:

[tex]\text{Remaining}=60-\dfrac{1}{3}\times 60[/tex]

[tex]\text{Remaining}=60-20[/tex]

[tex]\text{Remaining}=40[/tex]

The remaining area was divided into two equal parts. So, the area of each remaining part is:

[tex]\text{Area of each remaining part}=\dfrac{40}{2}[/tex]

[tex]\text{Area of each remaining part}=20[/tex]

Therefore, the area of each remaining part is 20 m².
