Answer:
\(0.01p + 0.05n = 8.80; n = 2p\)
\(P = 80\)
\(N = 160\)
Step-by-step explanation:
Hello!
EquationWe know that there are twice as many nickels as pennies, so we can say that n = 2p.
\(n = 2p\)Given the hint:
Pennies are worth $0.01Nickels are worth $0.05Since "N" and "P" represent the number of pennies, information that we don't know, we can fill in the blank spaces with the value, information that we do know.
\(?p + ?n = 8.80; n = 2p\)\(0.01p + 0.05n = 8.80; n = 2p\)SolutionSolve for PWe can plug in 2p for "N" in the equation to solve for "P".
\(0.01p + 0.05n = 8.80; n = 2p\)\(0.01p + 0.05(2p) = 8.80\)\(0.01p+0.1p = 8.80\)\(0.11p = 8.80\)\(p = 80\)There are 80 pennies.
Solve for NWe can plug in 80 in the second equation (N = 2p) to solve for N.
\(n = 2p\)\(n = 2(80)\)\(n = 160\)There are 160 nickels.
The equation: \(0.01p + 0.05n = 8.80; n = 2p\)
# of Pennies: \(P = 80\)
# of Nickels: \(N = 160\)

What is the value of y in the solution to this system of equations 6y+x= -59 x= -2y+9?
Answer:
y = - 17
Step-by-step explanation:
6y + x = - 59 → (1)
x = - 2y + 9 → (2)
substitute x = - 2y + 9 into (1)
6y - 2y + 9 = - 59
4y + 9 = - 59 ( subtract 9 from both sides )
4y = - 68 ( divide both sides by 4 )

Determine the amplitude of function
The amplitudes of functions are a) 8 and b) 6.
Given are the functions we need to determine the amplitude of function,
a) y = 8 Sin (x/2) + 3
b) y = 6 Cos x + 2
So,
To determine the amplitude of a trigonometric function, you can follow these steps:
For a sine function of the form y = A×sin(Bx + C) + D:
The amplitude is equal to the absolute value of the coefficient A.
For a cosine function of the form y = A×cos(Bx + C) + D:
The amplitude is equal to the absolute value of the coefficient A.
Let's apply these steps to the given functions:
a) y = 8×sin(x/2) + 3
The coefficient of sin in this function is 8, so the amplitude is |8| = 8.
Therefore, the amplitude of function a) is 8.
b) y = 6×cos(x) + 2
The coefficient of cos in this function is 6, so the amplitude is |6| = 6.
Therefore, the amplitude of function b) is 6.
Hence the amplitudes of functions are a) 8 and b) 6.

The measure of angle HGI from the given rhombus is 35°.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.
The given quadrilateral FGHI is a rhombus.
In a rhombus, diagonals bisect each other at right angles.
Here, (7x-1)°+(4x+3)°+90°=180°
11x+92=180
11x=88
x=8
Now, 4x+3=35°
So, m∠HGI=35° (Alternate interior angles)

Real-life Problems Question 10
Answer :
a) It is given that
Everyday a machine makes 500000 staples and puts them into the boxes.
The machine need 170 staples to fill a box
One box contans = 170 staples.
Total number of staples = 500000
Number of box required to fill 500000 staples = Total number of staples/No. of staples 1 box contains.
\( \: :\implies \) 500000 /170
\( :\implies \: \) 2941 (approx)
Therefore, 2941 boxes are required to fill with 500000 staples.
b) It is given that,
Each staple is made of 0.21 g of metal .
Total weight of metal = 1 kg = 1000 g
1 staple = 0.21 g
Number of staples = weight of metal/ Weight of 1 staple.
\( \: :\implies \) 1000/0.21
\( \: :\implies \) 4761 (approximately)
Therefore, 4761 staples can be made from 1 kg of the metal.

How to calculate your bi-weekly paycheck based on 20 hour weeks at a rate of $9.00 per hour. Also, You will need to deduct Federal Income Tax (11.9%) , State Income Tax (3.6%), F.I.C.A (7.65%), and professional dues. Lastly you will need to look determine whether or not you will be able to pay your monthly car insurance bill of $200.00?
To calculate your bi-weekly paycheck, follow these steps:
Step 1: Calculate the gross earnings:
Multiply the number of hours worked per week by the hourly rate.
20 hours/week * $9.00/hour = $180.00/week
Step 2: Calculate the total earnings for two weeks:
Multiply the weekly earnings by the number of weeks in a bi-weekly pay period.
$180.00/week * 2 weeks = $360.00
Step 3: Calculate the deductions:
Calculate each deduction separately and subtract them from the gross earnings.
Federal Income Tax: $360.00 * 11.9% = $42.84
State Income Tax: $360.00 * 3.6% = $12.96
F.I.C.A: $360.00 * 7.65% = $27.54
Professional Dues: Amount varies depending on the specific dues.
Total Deductions: $42.84 + $12.96 + $27.54 + Professional Dues
Step 4: Calculate the net earnings:
Subtract the total deductions from the gross earnings.
Net Earnings = Gross Earnings - Total Deductions
Once you have the net earnings, you can determine if it is sufficient to cover your monthly car insurance bill of $200. If your bi-weekly net earnings are greater than or equal to $200, you will be able to pay your car insurance bill.
It is important to note that these calculations are based on the information provided, and actual tax rates and deductions may vary depending on your specific circumstances and location.
Additionally, professional dues may differ depending on your profession. It is recommended to consult with a tax professional or payroll department for precise calculations.

Constraints:
\(2x- y \le 12\)
\(4x + 2y \ge 0\)
\(x + 2y \le 6\)
\(x,y\ge 0\)
Required
The maximum and the minimum values of z
To do this, we make use of graphical method.
Plot the constraints on a graph (see attachment)
Get the corner points from the points.
These are the points where \(x,y\ge 0\)
So, we have:
\((x_1,y_1) = (0,0)\)
\((x_2,y_2) = (0,3)\)
\((x_3,y_3) = (6,0)\)
Substitute these points in the optimization equation:
\((x_1,y_1) = (0,0)\)
\(z = 2x + 5y\)
\(z = 2 * 0 + 5 * 0 = 0\)
\((x_2,y_2) = (0,3)\)
\(z = 2 * 0 + 5 * 3 = 15\)
\((x_3,y_3) = (6,0)\)
\(z = 2 * 6 + 5 * 0 = 12\)

does 4/6 yard cover more area or less area than one square yard
Therefore, one square yard covers more area than 4/6 yard, because one square yard is equal to 1*1 = 1 square yard.
What is area?the area is the measurement of the size of a two-dimensional space or surface. It is typically measured in square units such as square meters (m²), square centimeters (cm²), square feet (ft²), or square inches (in²).
The concept of area is used in various fields, such as geometry, calculus, physics, and engineering. In geometry, the area of a shape can be calculated by multiplying the length and width of a rectangle, or by using formulas specific to different shapes such as the area of a triangle, circle, or parallelogram.
by the question.
One square yard covers a larger area than 4/6 yard.
One square yard is equivalent to an area of 3 feet by 3 feet or 36 inches by 36 inches, which is 1,296 square inches or 0.1111 square yards.
On the other hand, 4/6 yard is equivalent to an area of 4 feet by 8 inches or 48 inches by 72 inches, which is 3,456 square inches or 0.3333 square yards.
Now, to convert 2 feet to square yards,
we need to square the length in yards.

How to find the number of van, small trucks and large truck needed?The truck company plans to spend 10 million on 260 vehicles. Each commercial van cost 25,000 dollars. Each small truck 50,000 dollars and each large truck 50,000 dollars. They needed twice as many van as small truck
Therefore,
let
s = number of small truck
number of van = v
let
l = number of large truck
v + s + l = 260
25,000(v) + 50,000(s) + 50,000(l) = 10,000, 000
v + 2s + 2l = 400
Hence,
v = 2s
So,
2s + 2s + 2l = 400
4s + 2l = 400
2s + s + l = 260
3s + l = 260
2s + l = 200
s = 60
l = 200 - 2(60)
l = 200 - 120
l = 80
v = 2(600 = 120
