One high speed Internet provider has a $39 setup fee and charges $40 per month. Another
provider has a $60 setup and charges $30 per month. In how many months will the cost be the
same?
Answer:
2.1 months
Step-by-step explanation:
Let x represent the number of months
Set up expressions to represent the cost of each Internet provider
40x + 39 will represent the first one
30x + 60 will represent the other
Set these equal to each other and solve for x:
40x + 39 = 30x + 60
10x + 39 = 60
10x = 21
x = 2.1
So, the cost will be the same in 2.1 months
how do you Simplify -38=7+9x
Answer : -5
Step by Step Explanation:
You first combine like terms which is -38 and 7, so subtract the 7 from the right and add it to -38.
That will give you 45. Then divide 9x and -45 by 9. That will give you -5

which statement is true?
Answer:
is not
Step-by-step explanation:
Determine if the relation is a function. In your handwritten work, explain why or why not.
Please and Thank you!!!
Answer:
Step-by-step explanation:
Its not a function. The reason its not a function is because it doesnt pass the vertical line test. You could graph these points physically or you could think about it. The domain is the x value, while the range is the allowed y values. So by having the same x value relate to two different y values, just makes no sense. Imagine the function is x+4 and we are given in that graph that when x equals 6, the y equals 9 and 10. That isnt possible because we know the answer is 10, not 9, it cant be both.
Another way you could prove this is by graphing. If you try to take the slope in that interval where 6 coorelates to two y values. The change in y is 1, but the change in x is 0. When you divide 1/0, your calculator blows up. Try it
If there are 6 grams of fat in a snack how many grams of protein are there?
6 grams of fat in a snack then 50 grams of protein in snacks
The required amount of protein cannot be specified for the snack which has 6 grams of fat.
To determine If there are 6 grams of fat in a snack how many grams of protein are there.
Statistics is the study of mathematics that deals with relations between comprehensive data.
Here,
The composition of fat is given since the data is not given.
Proper static data is required to conclude the amount of protein for the corresponding amount of 6 grams of fat, so the amount of protein cannot be specified for the snack which has 6 grams of fat.
Thus, the required amount of protein cannot be specified for the snack which has 6 grams of fat.

For the set A=
-4
a) list the elements of A
b) find n(A)
c) Is A finite or infinite?
HELP
Answer:
a) A = {-3, -2, -1}
b) n(A) = 3
c) A is finite
Step-by-step explanation:
a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.
A = {-3, -2, -1}
__
b) n(A) is the number of elements in set A. Obviously, there are 3:
n(A) = 3
__
c) Since n(A) is not "infinity", the set A is finite.

D and e are complementary. If m\d=5x+3 and m\e=3x-1 what is x
Given:
∠d and ∠e are complementary angles.
m∠d=5x+3 and m∠e=3x-1
To find:
The value of x.
Solution:
If two two angles are complementary angles, them there sum is 90 degrees.
[tex]m\angle d+m\angle e=90^\circ[/tex] (Complementary angles)
[tex](5x+3)^\circ+(3x-1)^\circ=90^\circ[/tex]
[tex]8x+2=90[/tex]
[tex]8x=90-2[/tex]
[tex]8x=88[/tex]
Divide both sides by 8.
[tex]x=11[/tex]
Therefore, the value of x is 11.

Answer:
82/99
Step-by-step explanation:
1. Notice the length of the repeating pattern.
the pattern is 82 repeating, a 2-digit pattern
2. Notice where the repeating pattern starts, relative to the decimal point.
the repeating starts at the decimal point
3. If the repeating starts at the decimal point, use a pattern of repeating 9s of the same length as the denominator of the fraction
2 nines are the denominator: 82/99
4. Reduce the fraction if possible
this fraction cannot be reduced
As a simplified fraction, 0.828282... = 82/99
_____
Comment on more complicated cases
If the repeat does not start at the decimal point, or if the number contains an integer part, then the numerator of the fraction is found in a slightly different way. Let n be the number of repeating digits of the number x. The fraction is then ...
(10^n·x -x)/(10^n -1)
Example:
1.2345345345... a number with a 3-digit repeat not starting at the decimal point
(1234.5345... -1.2345...)/(1000 -1) = 1233.3/999 = 4111/3330
The multiplication by 10^n aligns the repeating parts so they cancel when you do the subtraction.

The perimeter and area of a rectangle with a length of 10 have the same numerical value. What is the width of the rectangle?
Answer:
b=2.5
Step-by-step explanation:
We know that,
Area of a rectangle= Length X Breadth
Perimeter of a rectangle= 2( Length + Breadth)
From the provided information we get that,
Area= Perimeter
lb=2(l+b)
Substituting l=10,
10b=2(10+b)
10b=20+2b
10b-2b=20
8b=20
b=20/8
b=2.5

Answer:
544 units²
Step-by-step explanation:
The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.
SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)
= 14×(10+10+12) +12×8
= 448 +96
= 544 . . . . square units
_____
The area of a rectangle is the product of its dimensions:
A = LW
The area of a triangle is half the product of its base and height:
A = (1/2)bh
Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.
