For his phone service, Hong pays a monthly fee of $30, and he pays an additional $0.07 per minute of use. The least he has been charged in a month is $124.92.
What are the possible numbers of minutes he has used his phone in a month?
Use m for the number of minutes, and solve your inequality for m.
Answers
Answer:
First, let's set up the equation
· We know the least total he's got in one month is $124.92
· In that one month, he was charged an additional $30 dollar fee.
· During the time he uses his phone, he is charged $0.07 per unknown minutes (which we can consider 'm').
It would look like this;
30 + 0.07m = 124.92
where $30 is the additional fee
$0.07 is the money he is charged per unknown minutes otherwise known as 'm'
$124.92 is the total of that whole month (which has been the least amount of money he used)
So now we solve for m:
30 + 0.07m = 124.92
-30 -30(get rid of any constants first by performing the inverse operation of addition, subtraction)
0.07m = 94.92
/0.07 /0.07 (isolate 'm' by applying the inverse operation of multiplication, division)
m = 1,356 minutes

3 = f
Step-by-step explanation:
3(6 - f) - 4 = 3f - 4
Distribute within Parenthesis
18 - 3f - 4 = 3f - 4
Combine like terms
14 - 3f = 3f - 4
Add 3f on both sides of the equation
14 = 6f - 4
Add 4 on both sides of the equation
18 = 6f
Divide by 6 on both sides of the equaiton to get your answer of
3 = f

what is the equation of the line that passes through the point (-3,7) and has a slope of 1/3
Answers
Answer:
y = 1/3 x + 8.
or in standard form:
x - 3y = -24.
Step-by-step explanation:
To answer this we use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
Here we have m = 1/3 and (x1, y1) = (-3, 7), so:
y - 7 = 1/3(x - (-3))
y - 7 = 1/3( x + 3)
y - 7 = 1/3 x + 1
y = 1/3 x + 8 .
This is the slope-intercept form of the equation.
Converting to standard form, we first multiply by 3:-
3y = x + 24
- x + 3y = 24
x - 3y = -24.
A bank offers a savings account that earns 0.5% interest each month.
Write an equation for the balance of the savings account after Y months.
Given an initial deposit of 500$ what will the account balance be after 15 months.
Answers
Answer
Step-by-step explanation:
This is exponential growth, so we would use the following equation
y=a(b)^x
500(1.005)^15
1. Initial amount is $500, since that's what we started with.
2. Add the following percentage by 100%
100%+0.5%= 1.005
3. We need to find the account balance after 15 months so raise it to the 15th power.
y= 500(1.005)^15
The balance after 15 months will be $538.84.

Mr. M traveled 5 miles fewer than twice the number of miles on Tuesday as Monday. On Wednesday he traveled 40 more than the square of the number of miles traveled Monday. If the total miles traveled was 1,024, write an equation to represent the total miles traveled on Monday, Tuesday and Wednesday.
Answers
Answer:
x² + 3x - 989 = 0 (where x is the number of miles traveled on Monday)
Step-by-step explanation:
Let x = number of miles traveled on Monday
Let y = number of miles traveled on Tuesday
Let z = number of miles traveled on Wednesday
Given:
Mr. M traveled 5 miles fewer than twice the number of miles on Tuesday as Monday⇒ y = 2x - 5
Given:
On Wednesday he traveled 40 more than the square of the number of miles traveled Monday⇒ z = x² + 40
Given:
Total miles traveled = 1024⇒ x + y + z = 1024
Substitute y = 2x - 5 and z = x² + 40 into x + y + z = 1024:
⇒ x + 2x - 5 + x² + 40 = 1024
⇒ x² + 3x + 35 = 1024
⇒ x² + 3x - 989 = 0 (where x is the number of miles traveled on Monday)

Rebecca ran the width of a field, a distance of 60 yards. Then she ran the length of the field,
a distance of 80 yards. Finally, she ran diagonally across it to get back to her starting point.
How far did Rebecca run?
Answers
Answer:
170 yards
Step-by-step explanation:
First off we know that Rebecca ran 60 yards at first. Then she ran another distance of 80 yards. She then ran diagonally across to get back. If she ran diagonally back that means would have run 30 yards back which is half of the first distance she ran.
(representation of how she ran)
1st: Up along the width |
2nd: sideways along the length ----
3rd: diagonally back to the starting point /
This would form a triangle. The first distance he ran would be halved to show the amount that Rebecca ran diagonally, we will represent this with x.
Equation representation:
60 + 80 = 140 yards
x = 60 divided by 2
x = 30 yards
60 + 80 + 30 = 170 yards

combined total of sixty bottles, how many
more bottles does Ameezy have than Beetle?
Answers
Answer:
30
Step-by-step explanation:
15 x 4 = 60, which means that Beetle has 15 bottles of water and that Ameezy has bottles. 45 - 15 = 30.
Hope this helps :)
Answer:
36 bottles.
Step-by-step explanation:
If you wrote them out, like 1 over 4, 2 over 8, and added up their totals at the bottom, you would eventually reach 60. The last column has 12 over 48, so we subtract 12 from 48, which gives us 36. So the answer is 36 bottles.

One brand of juice contains 0.05 of natural juice. Which is this decimal written as a percent?
A) 0.05%
B) 5%
C) 0.5%
D) 50%
Answers
Answer:
B.) 5%
Step-by-step explanation:
You'll need to multiply 0.05 by 100. Since 100 = 1, we are only multiplying by 1 and not changing the value of our number.
0.05 × 100 = 5
5/100 is 5 over 100 and means 5 per 100. 5 "per 100" means 5 "percent" or 5%
Therefore, 0.05 = 5%
I hope this helps! ^-^

The circle is centered at point C. Line segment PQ is parallel to SR.
What is the measure of angle QPS?
Answers
Answer:
m∠QPS = 112
Step-by-step explanation:
Shape PQRS is a cyclic quadrilateral as every vertex of the quadrilateral touches the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°.
⇒ m∠QPS + m∠QRS = 180°
⇒ m∠QPS + 68° = 180°
⇒ m∠QPS = 180° - 68°
⇒ m∠QPS = 112°
if p varies inversely as the square root of q, and p=12 when q=36, find p when q=16
Answers
Answer:
Step-by-step explanation:
p = k / sqrt(q)
The first job is to find k.
p = 12
q = 36
Solution for k
12 = k / sqrt(36)
sqrt(36) = +/- 6
Multiply both sides by +/-6
12 * +/- 6 = k
k = +/- 72
Solution for q = 16
p = +/-72/ sqrt(16)
p = +/- 72 / sqrt(16)
p = +/- 72 / +/-4
p = 18

Write down in terms of n, an expression for the nth term
of the following sequences:
a) 2 5 8 11 14
b) 9 11 13 15 17
Answers
Answer:
a) [tex]a_n=3n-1[/tex]
b) [tex]a_n=2n+7[/tex]
Step-by-step explanation:
a) From inspection, we can see that this is an arithmetic sequence as the difference between each term is the same:
14 - 11 = 3
11 - 8 = 3
8 - 5 = 3
5 - 2 = 3
(so the common difference = 3)
General equation of arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
(where [tex]a[/tex] is the first term and [tex]d[/tex] is the common difference between terms)
Given:
[tex]a=2[/tex][tex]d=3[/tex][tex]\implies a_n=2+(n-1)3[/tex]
[tex]\implies a_n=2+3n-3[/tex]
[tex]\implies a_n=3n-1[/tex]
b) From inspection, we can see that this is an arithmetic sequence as the difference between each term is the same:
17 - 15 = 2
15 - 13 = 2
13 - 11 = 2
11 - 9 = 2
(so the common difference = 2)
General equation of arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
(where [tex]a[/tex] is the first term and [tex]d[/tex] is the common difference between terms)
Given:
[tex]a=9[/tex][tex]d=2[/tex][tex]\implies a_n=9+(n-1)2[/tex]
