Amir has a bag of dimes and quarters. He has a total of 31 coins worth $5.20.
Let x represent the number of dimes and y represent the number of quarters.
Which system of equations would be used to find out how many dimes and quarters Amir has?
Answers
Answer:
B is the correct answer.
Step-by-step explanation:
This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?
x = dimes x = 0.10 or 0.1
y = quarters y = 0.25
31 coins
worth $5.20 = 5.2
x + y = 31
0.1x + 0.25y = 5.2

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?

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.

Find the value of sec theta, if cos theta =2/19; 0degrees less than and equal to theta less than and equal to 90 degrees.
a) 2/19
b) -19/2
c) -2/19
d) 19/2
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

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.

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

Answer:
x = 6
Step-by-step explanation:
Vertical angels are always equal, there fore angle A = angle B.
If angle A = angle B, and
angle A = 3x - 9 and angle B = x + 3, then
3x - 9 = x + 3
Now you can solve this like a regular inequality
Start by subtracting x by it's self then 3x to get both variables on one side.
2x - 9 = 3
Now you can add 9 to it's self and to 3 on the other side.
2x = 12
Finally, divide 2 by it's self and 12.
x = 6
Tony hit 9 out of 15 pitches at baseball practice yesterday. The following day at practice 45 pitches were made. How many pitches did Tony miss?
Answers
Answer:
18 pitches.
Step-by-step explanation:
I'm assuming the "9 out of 15" is the fraction of pitches Tony hit at baseball practice.
Hence, Tony missed 6 out of 15 pitches.
6/15 * 45
= 6 * 3
= 18 pitches.
Hope this helped!
Answer:
18
Step-by-step explanation:
You have to start with how many he hit.
Let the number of pitches he hit = x
9/15 = x / 45 Cross multiply
15x = 9 * 45 Combine the right side
15x = 405 Divide by 15
x = 405/15
x = 27
===================
The number he missed is 45 - 27 = 18

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
