in the United States 8•10⁹ text messages are sent every month. about how many text messages is this?
Answer:
8,000,000,000 text messages every month.
Step-by-step explanation:
[tex]8*10^9[/tex]
[tex]10^9[/tex] means there will be 9 zeroes at the end of 1. So it will be 1,000,000,000.
So 8* 1,000,000,000 will be 8,000,000,000 text messages every month.

Bye have a nice day
a father is 25 years older than his son.Five years ago he was 6 time old as his son was find their presents
Answer:
the present age of the father be x and the present age of the son be y.
It is given that man is 24 years older than his son that is:
x=y+24
x−y=24..........(1)
Also, 12 years ago, he was five times as old as his son that is:
(x−12)=5(y−12)
x−12=5y−60
x−5y=−60+12
x−5y=−48..........(2)
Now subtract equation 1 from equation 2 to eliminate x, because the coefficients of x are same. So, we get
(x−x)+(−5y+y)=−24−48
i.e. −4y=−72
i.e. y=18
Substituting this value of y in (1), we get
x−18=24
i.e. x=24+18=42
Hence, the present age of the father is 42 years and the present age of the son is 18 years.
Step-by-step explanation:
12 years ago, Juan was 2/3 the age he is now. Write and solve an equation to figure out how old he is now.
Answer:
he is now 18
Step-by-step explanation:
2/3 so their are 3 parts but you have 2 for know so 12 by 2 is 6 and 6 times 3 is 18.

Anton has 4 tiles.
One is a regular hexagon, one is a regular pentagon and two are equilateral triangles.
Anton thinks the 4 tiles will fit together perfectly, as shown in the diagram.
Show calculations to prove that he is wrong.
Answer:
Anthon is wrong (il dit des carabistouilles)
Step-by-step explanation:
It is a question of angle.
[tex]\widehat{\gamma}=180^o-\dfrac{360^o}{5} =108^o\\\\\widehat{\beta}=180^o-108^o=72^o\ and\ not\ 60^o\\[/tex]
The exterior angle of the pentagon is not equal to the interior angle of the equilateral triangle. So, he is incorrect.
What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
Anton has 4 tiles. One is a regular hexagon, one is a regular pentagon and two are equilateral triangles. Anton thinks the 4 tiles will fit together perfectly, as shown in the diagram.
The exterior angle of the hexagon is given as,
⇒ 360° / 6
⇒ 60°
The exterior angle of the pentagon is given as,
⇒ 360° / 5
⇒ 72°
And the internal angle of the triangle is given as,
⇒ 180° / 3
⇒ 60°
The exterior angle of the pentagon is not equal to the interior angle of the equilateral triangle. So, he is incorrect.

Answer:
78° and 65°
Step-by-step explanation:
(5)
The 2 angles lie on a straight line and sum to 180° , that is
x + 84 + x + 108 = 180
2x + 192 = 180 ( subtract 192 from both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
Then
x + 84 = - 6 + 84 = 78°
(6)
the angle opposite 8x is 9x - 7 ( corresponding to the 9x - 7 )
So 8x and 9x - 7are vertical angles and congruent
9x - 7 = 8x ( subtract 8x from both sides )
x - 7 = 0 ( add 7 to both sides )
x = 7
Then
9x - 7 = 9(7) - 7 = 63 - 7 = 56°

9.60% of students in a class studied for a test AND got an A on that test. 75% of students studied for the test. What is
the probability that a student got an A given that they studied for the test?
Probabilities are used to determine how likely it is for an event to happen.
(1) A roll of two dice
Let the dice be A and B. The sample space of each is:
[tex]A = \{1,2,3,4,5,6\}\\B = \{1,2,3,4,5,6\}[/tex]
To get the sample space (S) of the sum of the dice, we simply add up the individual element of both dice. So, we have:
[tex]S = \{(1+1),(1+2),(1+3),(1+4),(1+5),(1+6),.............,(6+1),(6+2),(6+3),(6+4),(6+5),(6+6)\}[/tex]
This gives
[tex]S = \{2,3,4,5,6,7,.............,7,8,9,10,11,12\}[/tex]
The complete sample space is:
[tex]S = \{2,3,3,4,4,4,5,5,5,5,6,6,6,6,6,7,7,7,7,7,7,8,8,8,8,8,9,9,9,9,10,10,10,11,11,12\}[/tex]
[tex]n(S) = 36[/tex] --- the total outcomes
The probability of rolling a sum of 7 is:
[tex]P(7) = \frac{n(7)}{n(S)}[/tex]
Where
[tex]n(7) = 6[/tex] ---- number of 7's in the sample space
So, we have:
[tex]P(7) = \frac 6{36}[/tex]
[tex]P(7) = 0.167[/tex]
The probability of rolling a sum of 7 is 0.167
(2) Restaurant
We have:
[tex]Soup = \{A,B,C,D\}[/tex]
[tex]Salads = \{1,2,3\}[/tex]
To get the sample space (S), we simply pick the individual elements of the above data. So, we have:
[tex]S = \{A1, A2, A3,B1, B2, B3,C1, C2, C3,D1, D2, D3\}[/tex]
(3) Disjoint events
Events are said to be disjointed if they cannot happen at the same time. 3 examples are:
Event 1: You are in China. Event 2: You are in NigeriaEvent 1: Heading towards north. Event 2: Heading towards southEven 1: Outcome of even number in a roll of die. Event 2: Outcome of an odd number in the same die(4) Bob and Sarah
Let
[tex]A \to[/tex] Bob gets to work on time
[tex]B \to[/tex] Sarah gets to work on time
[tex]P(A) = 80\% \\ P(B) = 90\%\\P(A\ n\ B) = 72\%[/tex]
The probability that Bob OR Sarah is late for work is represented as:
[tex]P(A'\ or\ B')[/tex]
This is calculated using:
[tex]P(A'\ or\ B') = P(A') + P(B') - P(A'\ n\ B')[/tex]
Where:
[tex]P(A') = 1 - P(A) = 1 - 80\% = 20\%[/tex]
[tex]P(B') = 1 -P(B) = 1 - 90\% =10\%[/tex]
[tex]P(A\ n\ B') = P(A) \times P(B') = 20\% \times 10\% = 2\%[/tex]
So, we have:
[tex]P(A'\ or\ B') = P(A') + P(B') - P(A'\ n\ B')[/tex]
[tex]P(A'\ or\ B') = 20\% + 10\% - 2\%[/tex]
[tex]P(A'\ or\ B') = 28\%[/tex]
[tex]P(A'\ or\ B') = 0.28[/tex]
The probability that Bob OR Sarah is late for work is 0.28
(5) Jake's Pizza
Let
[tex]A \to[/tex] The proportion of time they deliver on time
[tex]B \to[/tex] You get your pizza for free
So:
[tex]P(A) = 92\%[/tex]
You get your pizza for free if they didn't deliver within 30 minutes.
This means that:
[tex]P(B) = 1 - P(A)[/tex] --- Complement rule
So, we have:
[tex]P(B) = 1 - 92\%[/tex]
[tex]P(B) = 0.08[/tex]
The probability that you get your pizza for free is 0.08.
(6) Students and Soccer
Let:
[tex]A \to[/tex] Probability that a student likes soccer
So:
[tex]P(A) = 54\%[/tex]
If all 3 selected students like soccer, the probability is calculated as:
[tex]Pr = P(A) \times P(A) \times P(A)[/tex]
[tex]Pr = P(A)^3[/tex]
[tex]Pr = 54\%^3[/tex]
[tex]Pr = 0.157[/tex]
The probability that all 3 selected students like soccer is 0.157
(7) Students and Soccer
Let:
[tex]A \to[/tex] Probability that a student likes soccer
[tex]B \to[/tex] Probability that a student does not like soccer
So:
[tex]P(A) = 54\%[/tex]
[tex]P(B)= 1 - P(A)= 1 - 54\% = 46\%[/tex] ---- Complement rule
If all 4 selected students do not like soccer, the probability is calculated as:
[tex]Pr = P(B) \times P(B) \times P(B) \times P(B)[/tex]
[tex]Pr = P(B)^4[/tex]
[tex]Pr = 46\%^4[/tex]
[tex]Pr = 0.045[/tex]
The probability that all 4 selected students do not like soccer is 0.045
(8) Marbles
[tex]Blue = 6 \\ Green = 4 \\ Red = 5[/tex]
When the green marble is selected, we are left with
[tex]Blue = 6 \\ Green = 3 \\ Red = 5[/tex]
The probability of selecting a red marble at this point is:
[tex]P(Red) = \frac{Red}{Blue + Green + Red}[/tex]
[tex]P(Red) = \frac{5}{6+3+5}[/tex]
[tex]P(Red) = \frac{5}{14}[/tex]
[tex]P(Red) = 0.357[/tex]
The probability that the next marble you draw is red is 0.357
(9) Studying for test
Let
[tex]A \to[/tex] Students got an A
[tex]B \to[/tex] Students studied for test
So:
[tex]P(A\ n\ B) = 60\% \\ P(B) = 75\%[/tex]
The probability that a student got an A given that they studied for the test is represented as:
[tex]P(A | B)[/tex]
So, we have:
[tex]P(A | B) = \frac{P(A\ n\ B)}{P(B)}[/tex]
[tex]P(A | B) = \frac{60\%}{75\%}[/tex]
[tex]P(A | B) = 0.80[/tex]
The probability that a student got an A given that they studied for the test is 0.80

EFV and EDW are straight lines.
Find the value of x and of y.
Answers:
x = 72
y = 83
============================================================
Explanation:
Angle VFG is 50 degrees. The angle adjacent to this is angle EFG which is 180-50 = 130 degrees.
Angle HDW is 77 degrees. The supplementary angle adjacent to this is 180-77 = 103 degrees which is angle EDH.
Pentagon EFGHD has the following five interior angles
E = xF = 130G = 170H = 65D = 103Note that angles F = 130 and D = 103 were angles EFG and EDH we calculated earlier.
For any pentagon, the interior angles always add to 180(n-2) = 180(5-2) = 180*3 = 540 degrees.
This means,
E+F+G+H+D = 540
x+130+170+65+103 = 540
x+468 = 540
x = 72
---------------------------------------
Now focus your attention on triangle THS
We see that the interior angles are
T = yH = 65S = 32The angle H is 65 degrees because it's paired with the other 65 degree angle shown. They are vertical angles.
For any triangle, the angles always add to 180
T+H+S = 180
y+65+32 = 180
y+97 = 180
y = 180-97
y = 83
