Answer:

You can send 405 texts in 2008 without going over 100$

Step-by-step explanation:

Equation for 2008:

59$ for 200 texts + .20 dollars per text after that < or = $100

So minus $59 dollars

.20 * (number of txts) < 100 - 59

.20 * (number of txts) < 41

divide both sides by .2

number of txts < or = 205

so therefore you can send exactly 405 texts without going over $100

Then to find how much you would pay plug into this equation

If total number of texts is lower than 200 texts, then you would be paying $59, but if it is more then plug into the following equation

(Total number of texts - 200) * .20 + 59 = Total $ spent for a 2008 text plan per month.

The total number of texts that can be sent is 405 texts in 2008 without going over 100$. The amount will be $99.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The equation for 2008:

59$ for 200 texts + 0.20 dollars per text after that < or = $100 and minus $59 dollars

0.20 x  (number of texts) < 100 - 59

0.20 x  (number of texts) < 41

Divide both sides by 0.2

number of texts < or = 205

405 texts can be sent without going over $100

If the total number of texts is lower than 200 texts, then you would be paying $59, but if it is more then plug into the following equation

(Total number of texts - 200) x  0.20 + 59 = Total $ spent for a 2008 text plan per month.

( 405 - 200 ) x 0.2 + 59 = $99

Therefore,  the total number of texts that can be sent is 405 texts in 2008 without going over 100$. The amount will be $99.

Answer:

Step-by-step explanation:

The orthocenter is the point of intersection of the altitudes of the triangle. That is, each altitude goes through the orthocenter. Hence, the line from any given vertex through the orthocenter is perpendicular to the opposite side.

The attached figure shows the given points labeled A and B. Point A lies on the x-axis, as does the orthocenter, so the side opposite will be a vertical line (perpendicular to the x-axis).

The remaining side of the triangle will be perpendicular to the line from B through the origin. The line through B has slope 4/3, so the line containing side AC will have slope -3/4 and will go through point A. Its point-slope equation will be ...

  y -0 = -3/4(x +5)

We already know the x-coordinate of vertex C is the same as that of vertex B, so is x=3. Using this in the equation for side AC, we find the y-coordinate to be ...

  y = -3/4(3 +5) = -6

The coordinates of point C, the third vertex, are (3, -6).

By finding the probability that the unit digit is even, we will see that the probability that the 5-digit number will be even is P = 4/9.

So we have a 5-digit number, let's say that it is:

abcde

Now, we have 5 "slots" where we can put numbers from 1 to 9 (without replacement).

We want to find the probability that the number will be even, so we only care for the last digit, e (it must be even).

Let's assume that the first digit at which we assign its value is this, e, the last one.

For this digit we have 9 options, {1, 2, 3, 4, 5, 6, 7, 8, 9}

4 of these options are even numbers.

So there are 4 out of 9 cases where the last digit is even, then the probability that the 5-digit number will be even is just:

P = 4/9

Now the other four digits can be anything (even or odd), so we only care for the probability above.

The man traveled 20km by train.

Step-by-step explanation:

If x is the distance he traveled by train, you can write this equation to represent the situation:

[tex]10+x+2x=70[/tex]

Then, you can simply solve for x:

[tex]10+3x=70\\3x=60\\x=20[/tex]

The man traveled 20km by train.

[tex]10+(20)+2(20)=70\\10+20+40=70\\70=70[/tex]

The distance across a circle, going through the center is called Diameter.

The equation that represents the function is [tex]y = 2(\frac 12)^x[/tex]  

The graph is an exponential function, and it passes through the points:

[tex](x,y) = (1,1)\ (0,2)[/tex]

An exponential function is represented with:

[tex]y = ab^x[/tex]

At (0,2), we have:

[tex]ab^0 = 2[/tex]

This gives

[tex]a(1) = 2[/tex]

[tex]a = 2[/tex]

At (1,1), we have:

[tex]ab^1 = 1[/tex]

[tex]ab = 1[/tex]

Substitute 2 for (a)

[tex]2b = 1[/tex]

Divide both sides by 2

[tex]b = \frac 12[/tex]

Substitute values for a and b in [tex]y = ab^x[/tex]

[tex]y = 2(\frac 12)^x[/tex]

Hence, the equation that represents the function is [tex]y = 2(\frac 12)^x[/tex]

Answer:

15.42 inches

Step-by-step explanation:

-formula : perimeter of semi circle= πr+2r

r=3 inch

π.3+2.3

=3π+6

Answer:

15.425 or 6+3π

Step-by-step explanation:

If the radius of the circle is 3 inches and the diameter is double the radius, we know the diameter is 6 inches. Then we find half of the perimeter of a circle with radius 3. The perimeter formula of a cirle is 2πr. Plugging in the radius we get: 2(3)π or 6π. Then we divide by 2 as it is a semicircle and get 3π or ≈9.425. We add 6 to this and we get the answer of 15.425 or 6+3π.
