find the value of x


help please , i have a 17 in this class .

An isosceles triangle has two identical angles.

The three angles need to add up to 180 degrees.

If one angle is 100 then the other two angles added together need to equal 180-100 =‘80 degrees.

Since two angles need to be the same the other angles are 80 / 2 = 40 degrees each.

The answer is 40

Answer:

A. first answer on the left.

Step-by-step explanation:

If one of the angles is 100 then if the triangle is isosceles then the two remaining angles have to be either 100 and - 20 (which is impossible because at this level of math there is no such thing as an angle with a measure of - 20).

The minus 20 comes from every triangle having 180 degrees. 100 + 100 adds to 200, which means the third angle has to be the impossible measure of - 20.

The other possibility is that the given angle of 100 is the top angle and that leaves 80 degrees for the two isosceles angles.

2x = 80

x = 80/2

x = 40

The only possible answer is 40 - 40 - 100

Answer:

The substance's half-life is 6.1 days.

Step-by-step explanation:

The half-life of the substance can be calculated by knowing the constant decay:  

[tex] t_{1/2} = \frac{ln(2)}{k} [/tex]                          

k: is the decay constant = 0.1133 d⁻¹

Hence, the half-life is:      

[tex] t_{1/2} = \frac{ln(2)}{k} = \frac{ln(2)}{0.1133 d^{-1}} = 6.1 d [/tex]

Therefore, the substance's half-life is 6.1 days.

I hope it helps you!

Given,

Number of pieces = 24

Number of packages = 3

Each package has the same number of pieces.

So,

Number of pieces in 1 package

= Number of pieces / Number of packages

= 24 / 3

= 8

Solution :

Here we can use the Binomial distribution, as there are only two possible outcomes.

The given data:

n = 150

q = 98%

  = 0.98

p = probability of not finding relief = 1 - 0.98

                                                         = 0.02

A). The number of the individuals who do not find any relief from sinusitis is  :

E(x) = np

      = 150 x 0.02

      = 3

B). The uncertainty of my estimate is = [tex]$\sqrt{npq}$[/tex]

                                                              [tex]$=\sqrt{150 \times 0.02 \times 0.98}$[/tex]

                                                              = 1.716

Answer:

A) Number of mango trees

B) Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C)number of mango trees = 40% × 2230

D) 892 mango trees

Step-by-step explanation:

A) What is asked is the number of mango trees

B) We are given;

Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C) Number sentence is defined as when we use an equation or inequality to describe an expression using numbers and signs.

We have percentage of coconut trees = 60%.

Thus, percentage of mango trees = 100% - 60% = 40%

In this case, the number sentence is; number of mango trees = 40% × 2230

D) number of mango trees = 40% × 2230 = 892
