your cell phone plan is by the minute. each minute of use cost $0.10. create a relation that represents the amount spent, A, per minute, m, of call time. Then, use the relation to find the amount spent if you talk 65 minutes.
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
Thus, talking 65 minutes, $ 6.50 must be paid.

(iii) A relation between a and b such that point (a,b) isequidistant from the points (8,3) and (2,7)
Answer:
7.21 units
Step-by-step explanation:
GIven data
Point 1= (8,3)
x1= 8
y1= 3
Point 2= (2,7)
x2= 2
y2= 7
The expression for the distance between two points is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((2-8)²+(7-3)²)
d=√((-6)²+(4)²)
d=√36+16
d=√52
d= 7.21
Hence the distance between the points is 7.21 units

Monte recorded the gas mileage, in miles per hour, of ten different cars he is considering buying: 34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.
What is the median?
Answer:
29.4
Step-by-step explanation:
42+34=76
76+31=107
107+30+30=167
167+29=196
196+28=224
224+27=251
251+24=275
275+19=294
there are 10 cars that he wants
294/10=29.4
The median of the given data set is 29.5.
What are the mode and median?Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.
For example;
Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.
As per the given mileage set,
34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.
Write the above set in increasing order as
19,24,27,28,29,30,30,31,34,42
The median will be the middle value, since there is an even number so median will be as,
Median = (5th value + 6th value)/2
Median = (29 + 30)/2 = 29.5
Hence "The median of the given data set is 29.5".

Step-by-step explanation:
3) Josie's collection of 39 coins includes twice as many nickels than quarters. If
the sum of the nickels and quarters is $4.55, How many quarters does Josie
have in her collection?
Answer:
13 quarters, 26 nickels.
Step-by-step explanation:
n will be number of nickels, q will be number of quarters, and we have 39 total coins
so n + q = 39 (number of nickels + number of quarters = 39 coins.
The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)
which means
n + q = 39
2q + q = 39
3q = 39
q = 13
and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels
LMK if you have questions.
If you want to double check the money,
n(0.05) + q(0.25) = 4.55 is the equation to use.
26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55
Which table contains data with a nonproportional relationship?
A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 2, 3. Column 2 is labeled y with entries 6, 12, 18.
A 2-column table with 3 rows. Column 1 is labeled x with entries 2, 4, 6. Column 2 is labeled y with entries 0, 2, 4.
A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 2, 3. Column 2 is labeled y with entries 2, 4, 6.
A 2-column table with 3 rows. Column 1 is labeled x with entries 2, 4, 6. Column 2 is labeled y with entries negative 4, negative 8, negative 12.
Answer:
The second table, counting from the top.
X Y
2 0
4 2
6 4
Step-by-step explanation:
A proportional relationship is written as:
y = k*x
where k is called the constant of proportionality, is a real number different than zero.
Here we have different tables, if for two pairs (x, y) of the table we have the same value of k, then the relation is proportional. Also you can see that if x = 0, we have:
y = k*0 = 0
then a proportional relationship always has the point (0, 0)
A)
X Y
1 6
2 12
3 18
Let's use the first two pairs:
(1, 6)
6 = k*1
6/1 = k = 6
(2, 12)
12 = k*2
12/2 = k = 6
in both cases we have k = 6, then this is a proportional relationship.
B)
X Y
2 0
4 2
6 4
Here we can see the pair (2, 0)
This means that when x = 2, we have y = 0
Then this can not be a proportional relationship, because:
0 = k*2
k = 0
This is not a proportional relationship.
C)
X Y
1 2
2 4
3 6
Let's find k for the first two points.
(1, 2)
2 = k*1
2/1 = k = 2
(2, 4)
4 = k*2
4/2 = k = 2
In both cases we have k = 2, then this is a proportional relationship.
D)
X Y
2 -4
4 -8
6 -12
Let's find k for the first two points:
(2, -4)
-4 = k*2
-4/2 = k = -2
(4, -8)
-8 = k*4
-8/4 = k = -2
In both cases we have k = -2, then this is a proportional relationship.

Step-by-step explanation:
There is sales of 40% off of the original price. If a mobile phone has a sale price of $180, what was the original price? Choose the correct answer.
A) $200
B) $280
C) $300
D) 320$
Answer:
$300
Step-by-step explanation:
If the phone has a discount of 40% that means it cost 60% of the original price
X= original price (100%)
$180 = 60% of the original price
X = 100%
CROSS MULTIPLICATION
60X = 180x100
60X = 18000
Divide both sides by 60
X = 300

The ratio of three sides of a triangle are 5:9:11. There perimeter of the triangle is 325. Find the
measure of each side of the triangle
Answer:
65; 117; 143.
Step-by-step explanation:
1. if the ratio is 5/9/11 and the perimeter is a+b+c=325, then it is possible to write (for the perimeter):
5x+9x+11x=325;
2. to calculate the value of 'x':
x=13;
3. the required sides are:
5x=65; 9x=117; 11x=143.
