Rafael can choose plan a or Plan B for his long-distance charges. For each plan, cost (in dollars) depends on minutes used (Per month) as shown below.
Answers
Answer:
a. Plan B; $4
b. 160 mins; Plan B
Step-by-step explanation:
a. Cost of Plan A for 80 minutes:
Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:
f(80) = 8
This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.
Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.
Plan B will cost $12.
Therefore, Plan B cost more.
Plan B cost $4 more than Plan A ($12 - $8 = $4)
b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.
At 160 minutes, they both cost $16
The plan that will cost less if the time spent exceeds 160 minutes is Plan B.

Answer:
D. y = 76x
Step-by-step explanation:
First you find the gradient, by using the gradient formula
rise over run
380 - 228
---------------- <- division sign
5 - 3
152/2 = 76
Hence y = 76x + c
Find c by subbing points in. I am going to use this as an example (5, 380)
380 = 76(5) + c
380 -380 = c
c = 0
Hence, y = 76x

A square has an area of 200 square feet. Between what two consecutive integers would the
length of each side fall?
HELP ME PLEASE
Answers
Answer:
14 & 15
Step-by-step explanation:
The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].
So we take [tex]s = \sqrt{200} = 14.14[/tex]
And this is between the integers 14 and 15.

-12x+(-4)=56
-2.1x+(-3.9)=10.8
Answers
Answer:
X=-5
X=-7
Step-by-step explanation:
-12x+(-4)=56
rewrite the equation to -12x-4=56
add 4 to both sides
-12x=60
Divide by -12 on both sides
x=-5
-2.1x+(-3.9)=10.8
-2.1x-3.9=10.8
-2.1x=14.7
divide by -2.1 on both sides
x=-7

Solve the following literal equation for x.
ax-b/c=d
Answers
Answer:
x = (d + b/c)/a
or x = d/a + ba/c
Step-by-step explanation:
1. ax - b/c = d
2. ax = d + b/c
3. x = (d + b/c)/a (can also be written as x = (d + b/c)*1/a)
4. x = d/a + ba/c
Step 1 is given.
In step 2, b/c was added to both sides of the equation. This works because division is ahead of subtraction in the order of operations.
In step 3, both sides were divided by a.
(optional) In step 4, 1/a was multiplied by the values inside the parenthesis as a means to further simplify the equation.

A survey o 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at at night. Tara claims that 33:55, 48:88 and 20:65 are possible ratios from this data. Jim claims that 35:100, 405:100 and 200:100 are possible ratios from the data who is correct? Explain
Answers
Answer:
Jim is correct.
Step-by-step explanation:
Given that:
Total people = 100
People who exercise in morning = 35
People who exercise in the afternoon= 45
People who exercise in the evening = 20
Ratio claimed by Tara = 33:55, 48:88, and 20:65
Ratio claimed by Jim = 35:100, 45:100, and 20:100
To find:
who is correct ?
Solution:
Looking at the ratio claimed by Tara, the ratio are number which are not known to us.
Therefore, the ratio claimed by Tara can not be correct.
Now, looking at the ratio claimed by Jim:
35:100, 45:100, and 20:100
35 is the number of people who exercise in morning.
45 is the number of people who exercise in evening.
20 is the number of people who exercise in night.
and 100 is the total number of people.
Therefore, this ratio represents the "Part-to-whole" ratio.
So, Jim is correct.

Explicit formula -6,-10,-14
Answers
Answer:
Tn = -6 + (n - 1)(-4)
Step-by-step explanation:
The explicit formula is this: Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference.
The first term is given to you and that is -6.
The common difference is -4 because:
d = -10 - (-6)
d = -10 + 6
d = -4
Hence: Tn = -6 + (n - 1)(-4)
