Triangles

Given :-

A diagram with angles 74°, 35° and ( 6x + 17 )°.

To Find :-

Value of x.

Concept Used :-

Sum of all angles in a triangle is 180°.

Solution :-

Sum of all angles in a triangle = 180°

74° + 35° + 6x + 17° = 180°

6x + 74° + 35° + 17° = 180°

6x + 126° = 180°

6x = 180° - 126°

6x = 54°

x = 9

Answer :-

So, value of x is 9.

se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m ¿cual es el area que se va a pintar?​

Answers

Answer:

16.8 metros cuadrados.

Step-by-step explanation:

Dado que se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m, y que el área de un hexágono es igual al perímetro multiplicado por la apotema, y dicho resultado dividido por 2, para determinar cuál es el área que se va a pintar se debe realizar el siguiente calculo:

((6x3) x 2.8) / 2 = X

(12 x 2.8) / 2 = X

33.6 / 2 = X

16.8 = X

Así, el área que se va a pintar es de 16.8 m2.

A utility company charges $0.12 per kilowatt-hour for energy a customer uses.They give a credit of $0.0025 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves.A customer has a charge of $82.04 and a credit of -$4.10 on this mouth bill. How many kilowatt-hours did they use (Nearest-whole number?

Answers

Answer:

2,324.

Step-by-step explanation:

Given that a utility company charges $ 0.12 per kilowatt-hour for energy a customer uses, and they give a credit of $ 0.0025 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves, if a customer has a charge of $ 82.04 and a credit of - $ 4.10 on this mouth bill, to determine how many kilowatt-hours did they use the following calculation must be performed:

(82.04 / 0.12) + (-4.10 / - 0.0025) = X

683,666 + 1,640 = X

2,323.66 = X

Thus, rounded to the nearest whole number, users used 2,324 kilowatts per hour.

Arsenic is toxic to humans, and people can be exposed to it through contaminated drinking water, food, dust, and soil. Scientists have devised an interesting new way to measure a person's level of arsenic poisoning: by examining toenail clippings. In a recent study,1 scientists measured the level of arsenic (in mg/kg) in toenail clippings of eight people who lived near a former arsenic mine in Great Britain. The following levels were recorded: 0.8, 1.9, 2.7, 3.4, 3.9, 7.1, 11.9, 26.0
Do you expect the mean or the median of these toenail arsenic levels to be larger?

Answers

Answer:

The mean, because the outlier values are above the mean.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is given by the sum of all values of the data-set divided by the number of values.

Median:

The median of a data-set is the value that separates the lower 50% from the upper 50% of the sorted set.

0.8, 1.9, 2.7, 3.4, 3.9, 7.1, 11.9, 26.0

Finding the median, since it is easier.

8 values, the median is the mean between the 4th and the 5th values. (3.4+3.9)/2 = 3.65

The values below the median are quite close to it, while those above it are considerably more distant, considered outliers, which means that we should expect the mean to be larger than the median.

Answer:

x=3

Step-by-step explanation:

2⋅x=6

First, we multiply the 2 and the x

2x=6

Next, we transfer the 2 over to the 6. When we do that, we are dividing because we do the opposite of multiplication.

$83.84
$4,085.00
$4,083.84
$85.00

Answers

9514 1404 393

Answer:

  (c)  $4,083.84

Step-by-step explanation:

The amount due is ...

  A = P(1 +rt)

where P is the amount borrowed, r is the annual rate, and t is the number of years. For "exact interest", we use 365 days in a year, so the number of years is 90/365.

  A = $4000(1 + 0.085×90/365) ≈ $4083.84

Juan's loan will have a value of $4083.84 at maturity.

Answers

Answer:

[tex]h(5h-12g)[/tex]

Step-by-step explanation:

[tex]5h^2-12hg[/tex]

When we factor expressions, we look for factors within the terms that are alike, or in other words, we look for common factors. Here, [tex]5h^2[/tex] and [tex]12hg[/tex] only have one common factor: [tex]h[/tex]. Therefore, to factorize this expression, divide both terms by [tex]h[/tex].

[tex]= h(\frac{5h^2}{h}-\frac{12hg}{h} )\\= h(5h-12g)[/tex]

Now, we've "carried" [tex]h[/tex] out of the expression and have therefore factored it.

1.1. What is the earned value of the project at Week 8?

Answers

Answer:

the earned value of the project is $9,900

The computation of the earned value of the project is shown below:

As we know that

CPI = Earned value ÷ Actual cost

1.1 =  Earned value ÷ $9,000

So, the earned value is

= 1.1 × $9,000

= $9,900

hence, the earned value of the project is $9,900
