Under her cell phone plan, Ella pays a flat cost of $58.50 per month and $3 per gigabyte, or part of a gigabyte. (For example, if she used 2.3 gigabytes, she would have to pay for 3 whole gigabytes.) She wants to keep her bill under $65 per month. What is the maximum whole number of gigabytes of data she can use while staying within her budget?
Answers
The maximum number of gigabytes of data she can use while staying within her budget is 2 gigabytes.
Given that Ella pays a flat cost of $58.50, and per gigabyte used have to pay $3. If she uses g gigabytes she has to pay $3xg.
Now we have to find the maximum whole number of gigabytes data, she can use within her budget.
Her budget is less than $65.
We can create a inequality expression for this, as follows.
58.50+3g< 65
Calculating further, we get
3g<65-58.50
3g<6.5
g<6.5/3
g<2.163.
Therefore, the maximum whole of gigabytes, she should use to keep the expense within budget is 2 gigabytes.

If a different number in domain of a function have different outputs the function is called?
Answers
A function is a rule that assigns each input exactly one output. We call the output the image of the input. The set of all inputs for a function is called the domain.
A function is one-to-one if no two elements in the domain correspond to the same element in the range.
Thus, if a different number in the domain of a function has different outputs the function is called a one-to-one function

Answers
Angle A is 35° and Angle B is 145°
Supplementary angles are angles that give 180° when added together
Angle A and Angle B are supplementary angles such that
∠A + ∠B = 180°
Given that ∠A is acute angle and ∠B is obtuse angle
also , ∠A = 2x+5 and ∠B = 6x+55
using supplementary angle property ,
2x+5 + 6x+55 = 180

2. Solve the system of equations: *S 2x – 4y = 201x=4x = 4=
Answers
EXPLANATION
Since we have the system of equations:
(1) 2x - 4y = 20
(2) x = 4
Plugging in x=4 into (1):
2*4 - 4y = 20
Multiplying numbers:
8 - 4y = 20
Subtracting -8 to both sides:
-4y = 20 -8
Subtracting numbers:
-4y = 12
Dividing both sides by -4:
y = 12 / -4
Simplifying:
y = -3

Answers
Hello there. To solve this question, we'll have to remember some properties about mixed fractions.
5 book weight a total of 6 2/5 pounds. If each book weighs the same amount, how much does each book weigh?
We start by converting the fraction from the mixed fraction notation to the normal notation:
Therefore we have:
Now, suppose each book weigh x pounds. 5 books weight will be equal to 5x.
If 5 books weigh 32/5, then we have the following equation:
Divide both sides of the equation by a factor of 5
To find the value of this fraction, the trick is to multiply it by 4/4 (when the denominator is 25):
Each book weighs 1.28 pounds.

Answers
Answers:
x = 3
x = 5
Explanation:
In the function, the first set represents the x and the second set represents f(x), so to find for which values of x does f(x) = 4, we need to identify the beginning of the arrows that end in the number 4.
Therefore, these numbers are 3 and 5. It means that x = 3 and x = 5 make f(x) equal to 4.
So, the answers are x = 3 and x = 5.

Answers
72.2 square feet of wood will the company need to cover the deck designer shaped like a regular pentagon and a trapezoid.
To find the total wood required we need to add the area of pentagon and area of trapezoid.
Firstly we will draw the 5 similar triangle in the pentagon as shown below:
Lets name one triangle as ABC.
Given, radius of pentagon = 4.25 ft. (Let x)
Now, in triangle ABC,
BD=DC=2.5 ft. (half of the BC)
By applying Pythagoras theorem,
[tex]AB^{2} =AD^{2} +BD^{2} \\AD=\sqrt{AB^{2} -BD^{2} } \\AD=\sqrt{11.81} \\AD=3.44 ft.[/tex]
We know that AD is the height of triangle ABC.
So, Height = AD = 3.44 ft.
Area of triangle ABC = [tex]\frac{1}{2}[/tex] * base * height
=[tex]\frac{1}{2}[/tex] * 5 ft. 3.44 ft. = 8.59 square feet.
Area of pentagon = area of 5 similar triangle
= 5 * area of triangle ABC
= 5 * 8.59 = 42.96 square feet
Area of trapezoid = [tex]\frac{1}{2}[/tex] * (sum of the parallel side) * height
= [tex]\frac{1}{2}[/tex] * (5+8) * 4.5
= [tex]\frac{1}{2}[/tex] * 13 * 4.5 = 29.25 square feet.
Total square feet of wood required = area of pentagon + area of trapezoid
= 42.96 + 29.25 = 72.21 square feet
Rounding to one decimal place 72.21 square feet ≈ 72.2 square feet.
Thus, 72.2 square feet of wood will the company need to cover the deck designer shaped like a regular pentagon and a trapezoid.

On a certain day the probability of rain is 80% probability of thunder is 3/5 and the probability of both is 2/5. What is the probability that it will rain or thunder?
Answers
The probability it will rain or thunder = 100%

P(rain) = 4/5 (simplest term in fraction)
Probability of thunder = 3/5
P(thunder) = 3/5
Probability of both rain and thunder = 2/5
P(rain and thunder) = 2/5

To find the probability of P(rain or thunder), we will apply the formula for the addition rule on any two events:

Answers
his heart would beat 432 times in 3 minutes
Explanation
we can easily solve this by using a rule of three,
then
Step 1
to do that we need the same measure unit for the time, let's use seconds
so, we need to convert 3 minutes into seconds,
the equivalence is
[tex]1\text{ minute = 60 seconds}[/tex]hence, to convert from minutes into seconds just mutlply by 60
then
[tex]3\text{ minutes}\Rightarrow3\cdot60\text{ seconds=180 seconds}[/tex]Step 2
now, let's make the proportion
let x represents the number of times his heart would be in 180 seconds( 3 minutes)
so
[tex]\begin{gathered} \text{if} \\ 24\text{ beats}\Rightarrow10\text{ s} \\ \text{then} \\ x\text{ beats}\Rightarrow180\text{ s} \end{gathered}[/tex]so, the proportion is
[tex]\begin{gathered} \frac{24\text{ beats}}{10\text{ s}}=\frac{x}{180\text{ s}} \\ \frac{24}{10}=\frac{x}{180} \\ \end{gathered}[/tex]finally, to solve for x multiply both sides by of the equation by 180 and reduce
[tex]\begin{gathered} \frac{24}{10}=\frac{x}{180} \\ \frac{24}{10}\cdot180=\frac{x}{180}\cdot180 \\ \frac{4320}{10}=x \\ 432=x \end{gathered}[/tex]therefore, his heart would beat 432 times in 3 minutes
