An on-demand movie company charges $2.95 per movie plus a monthly fee of $39.95. Which expression represents the yearly cost for x movie rentals?
Answer:
2.95 x + 39.95 (12)
Hope this helps!!
The yearly cost for a student's movie rentals with a monthly subscription fee and a per-movie fee is expressed as $479.40 + $2.95x, where x is the number of movies rented.
Explanation:The yearly cost for x movie rentals from an on-demand movie company that charges a monthly fee and a per-movie fee can be represented by an algebraic expression. To find this expression, we need to account for both the monthly fee and the cost per movie.
The monthly fee is $39.95, so over one year, this fee would be 12 times $39.95.
For each movie rented, there is an additional charge of $2.95. If x movies are rented over a year, this cost is x times $2.95.
Combining these two costs gives us the total yearly cost:
Yearly Cost = (12 \(\times\) $39.95) + ($2.95 \(\times\) x)
This can be simplified to:
Yearly Cost = $479.40 + $2.95x

There are approximately 45 hundred species of mammals on Earth and 2.8 x 10 to the 4 species of fish. What is the difference in the number of species?
This is SCIENTIFIC NOTATION
Answer:
23500
Step-by-step explanation:
We are given that
Number of species of mammals on earth=approximately 45 hundred=4500
Number of species of fish=[tex]2.8\times 10^4=2.8\times 10000=28000[/tex]
We have to find the difference between the number of species of mammals and fish.
In order to find the difference in the number of species we will subtract number of species mammals from the number of species of fish.
Difference=28000-4500=23500
Hence, the difference between the number of species of mammals and fish=23500
Answer:
23,500
Step-by-step explanation:
45 hundred = 45 × 100 = 4,500
2.8 × 10^4 = 28,000
28,000 - 4,500 = 23,500

We are given with four roots. they are the x intercepts
x intercepts are [tex]−6 , −2 , 1,[/tex] and 3
The polynomial has degree 4, the polynomial goes up on both sides
We look at the graph that has x intercepts [tex]−6 , −2 , 1,[/tex] and 3 and both ends of the graph goes up
option B is correct
The graph that could be the graph of f(x) is;
The second graph which is the one at the top right
We are told that;
Degree of polynomial f(x) = 4; This means it has 4 roots
Roots of polynomial = -6, -2, -1 and 3
The roots of a polynomial simply means the values of x at which the function f(x) is equal to zero. This simply means the x- intercept is the root.
Thus, the x-intercept of the correct graph should be at;
x = -6; x = -2 ; x = -1 and x = 3
Looking at the given graphs, the only one that has its' x-intercepts at x = -6; x = -2 ; x = -1 and x = 3 is the second graph at the top right.

If PS || QR what is the measure of angle RSP?
Option B is correct. The measure of m<RSP is 49 degrees
From the diagram shown
3x + 2x + 1 + 8y - 13 = 180
5x + 8y - 12 = 180
5x + 8y = 180 + 12
5x + 8y = 192 ................. 1
Also, since PQ is parallel to PS, hence;
5y +14 = 8y - 13 (alternate interior angle)
5y - 8y = -13 - 14
-3y = -27
y = 27/3
y = 9
Substitute y = 9 into equation 1
5x + 8y = 192
5x + 8(9) = 192
5x + 72 = 192
5x = 192 - 72
5x = 120
x = 120/5
x = 24
Get the measure of <RSP
m<RSP = 2x + 1
m<RSP = 2(24) + 1
m<RSP = 48 + 1
m<RSP = 49degrees
Hence the measure of m<RSP is 49 degrees

Molly earns $8 per hour at her job. Last month, Molly worked for 45 hours. On her paycheck, Molly noticed that she paid $38.50 for federal income tax, $22.32 for Social Security, and $5.22 for Medicare. Molly's net income was
Molly's gross income is $360, and after subtracting her total deductions ($66.04), her net income is $293.96. This demonstrates the difference between gross and net income.
Explanation:To find Molly's net income, we will first need to calculate her gross earnings, and then subtract her deductions. Molly's gross earnings are her hourly wage multiplied by the number of hours she worked, so: $8/hr * 45 hours = $360.
Next, we add up Molly's deductions: $38.50 (federal tax) + $22.32 (Social Security) + $5.22 (Medicare) = $66.04.
Finally, to determine Molly's net income, we subtract her total deductions from her gross earnings: $360 - $66.04 = $293.96.
This example illustrates the concept of gross income versus net income. Gross income is the total amount earned before deductions, and net income is the amount left after deductions have been subtracted, which is the exact amount the employee receives in their paycheck.

If two sides of a triangle measure 12 and 7, which cannot be the perimeter of the triangle
38 cannot be the perimeter of the triangle.
What is Triangle Inequality Theorem?The sum of any two sides of a triangle is greater than or equal to the third side.
Given:
Two sides are 12 and 7.
Using Triangle Inequality Theorem, we have
In ΔABC,
AB + BC > CAAC + CB > BAAB + CA > BCSo,
12 + 7 > C
19 > C
C < 19
So, the third side should be less than 19.
Let us take maximum possible values,
C =18.999
Then, perimeter will be,
12 + 7 + 18.999 = 37.999
Hence, 38 cannot be the perimeter.

How I got 4 is you divide 30\ 120 =4
After 120 days there will be 160 rabbits on the farm.
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
Rabbits population can double every 30 days.
Initially there are 10 rabbits in a farm.
So, after 30 days there would be 10 × 2 = 20 rabbits.
After next 30 days, there would be
20 × 2
= 10 × 4
= 10 × 2²
= 40 rabbits.
Let t be the number of days and x be the number of rabbits.
So, we have an equation:
[tex]x=10\times2^{\frac{t}{30} }[/tex]
No, we find the number of rabbits after 120 days.
t = 120
So, the equation becomes,
[tex]x=10\times2^{\frac{t}{30} }\\\\x=10\times2^{\frac{120}{30} }\\\\x=10\times2^{4}\\\\x=10\times 16\\\\x=160[/tex]
Therefore, after 120 days there will be 160 rabbits on the farm.

Write an equation of a line that includes the point (22,12) and has a slope of 4 in standard form
The equation of the line that passes through the point (22,12) and has a slope of 4 is; y = 4x - 76
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Where x₁ - x coordinate and y₁ - y coordinate
Point (22,12)
Then Slope m =4
Now Write the equation as
y - 12 = 4(x - 22)
y = 4x - 76
Hence, the standard form of the line is; y = 4x - 76
