Answer:
The explicit formula that represents the amount of money left on the card
is a[tex]_{n}[/tex] = 53.25 - 3.25n
The value of the card after 12 lunches is $14.25
Step-by-step explanation:
The explicit formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where
a[tex]_{n}[/tex] is the nth terma is the first termd is the common difference between each 2 consecutive termsIn the question
∵ You have 50 dollars
∵ The money left after lunch on Monday is 46.75 dollars
∵ The money left after lunch on Tuesday is 43.50 dollars
∴ The terms of the sequence are 50, 46.75, 43.50
∵ 46.75 - 50 = -3.25
∵ 43.50 - 46.75 = -3.25
→ That means there is a common difference between each 2 terms
∴ d = -3.25
∵ a = 50
→ Substitute the values of a and d in the rule above
∴ a[tex]_{n}[/tex] = 50 + (n - 1)(-3.25)
→ Simplify it
∵ a[tex]_{n}[/tex] = 50 + -3.25(n) + -3.25(-1)
∴ a[tex]_{n}[/tex] = 50 - 3.25n + 3.25
→ Add the like terms
∴ a[tex]_{n}[/tex] = 53.25 - 3.25n
∴ The explicit formula that represents the amount of money left on the
card is a[tex]_{n}[/tex] = 53.25 - 3.25n
∵ n is the number of lunches
∴ n = 12
→ Substitute n by 12 to find the amount of money left on the card
∵ a[tex]_{12}[/tex] = 53.25 - 3.25(12)
∴ a[tex]_{12}[/tex] = 14.25
∴ The value of the card after 12 lunches is $14.25
Line t has an equation of y = -1/2 x + 7. Line u is parallel to line t and passes through
(4, -6). What is the equation of line u?
Answers
Answer:
y = -1/2x - 4
Step-by-step explanation:
Let equation of line u be y = mx + c
since line t and line u are parallel, slope/gradient of both lines are the same (aka m = -1/2)
sub (4, -6):
-6 = -1/2(4) + c
c = -4
therefore, equation of line u is y = -1/2x - 4

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
sales
I will give brainlest
Answers
Answer:
18
Step-by-step explanation:
So base of 300/week.
We subtract 300 from 1020, leaving 720.
Divide 720 by 40 (because that is the amount per sale), we get 18.
A photograph of sides 35cm by 22cm is mounted onto a
frame of external dimension 45cm by 30cm. Find the area
of the border surrounding the photograph.
Answers
===================================================
Work Shown:
A = area of smaller rectangle
A = length*width
A = 35*22
A = 770
B = area of larger rectangle
B = length*width
B = 45*30
B = 1350
C = area of the border only
C = B - A
C = 1350-770
C = 580 square cm
Step-by-step explanation:
Dimension of photograph is 35cm and 22cm.
And external dimension of photo frame is 45cm and 30cm
So, the area of the border surrounding the photograph=Area of photo frame−Area of photo.
So, The area of the border surrounding the photograph=45×30−35×22
=1350−770=580cm

how would i find the slope and y intersept of 3y=5x-18
Answers
Answer:
y=5/3x−6
5/3 is your slope
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 5x - 18 ( divide all terms by 3 )
y = [tex]\frac{5}{3}[/tex] x - 6 ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex] and y- intercept c = - 6

the sum of the angles in a pentagon is always 540 so do
540-131-108-107-110=84
Answer:
84
Step-by-step explanation:
The picture shown is 5 sided polygon
By using the formula (n - 2) * 180
We would get (5 - 2) * 180
3 * 180 = 540
We first add
131 + 108 + 107 + 110 + x = 456 + x
With the angle of the entire polygon, we would subtract which would give us the value for x
540 - 456 = 84

Answers
Answer:
19/2
Step-by-step explanation:
This problem is a problem desgined to test your basic understanding of Trigonomic functions and there applictoins.
Sec theta is the inverse of cos theta, which means sec theta is equal to adjecent / opposite.
They already gave you cos theta which is 2/19
We should know that from 0 to 90 degrees, sec theta is postive.
so sec theta is 19/2

Step-by-step explanation:
You are tasked with buying pizza for a party that has 100 guests. 40 guests are children, and 60 guests are adults. Half of the children want pizza, and two thirds of the adults want pizza. Children will eat one slice of pizza, and adults will eat two slices of pizza. A pizza pie can be cut into 8 slices and costs $9 dollars per pie.
Answers
Total slices required for children,
[tex]C = \dfrac{40}{2}\times 1\\\\C = 20\ slices[/tex] .
Total slices required for adults,
[tex]A=\dfrac{2}{3}\times 60\times 2\\\\A = 80\ slices[/tex]
So, total slices required are, 20 + 80 = 100 .
Number of pizza, n = 100/8 = 12.5
So, he has to order 13 pizza cause pizza cannot be purchased in fraction.
Total price, P = 13 × 9 = $117 .
Hence, this is the required solution.
