Write and solve the system of equations needed to model this situation: You have thirty coins
a total value of $3.40, which are made up of nickels, dimes, and quarters. There are twice as many
nickels than quarters. How many of each type of coin do you have?
The system of equations for the given conditions in question includes equation: 3.40 = 0.05x + 0.1y + 0.25z, and 2x = z. and we have 2 nickels, 23 dimes, and 4 quarters.
What is system of equations?
A system of equations is a collection of some equations with one or more numbers of variables. Systems of equations have solutions that are either the variable mappings that satisfy each component equation or the intersections of all of these equations.
Let the quantities of nickels, dimes, and quarters are x, y, and z respectively.
We know that, 1 nickel = $0.05, 1 dime = $0.1, and 1 quarter = $0.25
So, the values of nickels, dimes, and quarters would be value of one times total quantity.
Nickels = 0.05x, dimes = 0.1y, and quarters = 0.25z
As given in the question, the total value is 3.40
So, we get equation:
3.40 = 0.05x + 0.1y + 0.25z
Also it is given that there are twice as many nickels than quarters.
2x = z
Combining above two equations
3.40 = 0.05x + 0.1y + 0.25(2x)
3.40 = 0.05x + 0.1y + 0.5x
3.40 = 0.55x + 0.1y
Lets put 2 in place of x, we get y
(3.40 - 1.1)0.1 = y
y = 23.
Now, putting values of x, y in equation to get value of z
3.40 = 0.05(2) + 0.1(23) + 0.25z
3.40 = 0.1 + 2.3 + 0.25z
(3.40 - 2.4)/0.25 = z
z = 4
Therefore, we have 2 nickels, 23 dimes, and 4 quarters.

The principal amount is $693.33.
What is Simple Interest?Simple interest is a quick and simple approach to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount.
The formula is
Simple Interest = P x R x T/100
Given:
Interest = 78
Rate= 7.5%
Time= 1 and half year = 1.5 year
Now, Simple Interest= P x R x T / 100
78 = P x 7.5 x 1.5 / 100
7800= P x 11.25
P = 7800/11.25
P = 693.33
Hence, the principal amount is $693.33.

You went to an action figure shop to buy a figure of your favorite anime character. The purchase price was $20, and the selling price was $30. You gave the shop owner $100, but the owner didn't have any change. So he went to the neighboring shop, got change for $100, and gave you $70. Unfortunately, the neighboring shop owner found out that the 100-dollar bill given to him was fake, so he went to the action figure shop and got back his change of $100. Now the question is, how much did the owner of the action figure store lose in total?
The owner loses the figure and the $70 that gives back, so the total amount he loses is $90.
How much did the owner of the action figure store lose in total?
We know that the owner initially has a figure whose price is $20, and he sells it for $30.
Then, he sells it for a $100 bill, so he gives $70 back.
The problem is that the $100 bill was fake, so at this point the total amount that he loses is:
The value of the action figure (which is $20) plus the $70 that he gives back.
Adding these two we get:
$20 + $70 = $90
The owner loses $90 in total.

Based on the number of dice rolled, the probability of getting the sum of 6, and 4 and 6 or 4 can be found to be:
Probability of getting sum of 6 = 5 / 36Probability of getting sum of 4 = 1 / 12Probability of getting sum of 6 or 4 = 2 / 9How to find the probability?Probability of getting sum of 6:
(1 and 5) (2 and 4) (3 and 3) (4 and 2) ( 5 and 1)

A car travels a distance of 100km for 1h38min45sec.a)Round off the time to the nearest 1/4 hour b)Use the rounded time to find the average speed for the journey
Answer: 57.14 km/hr
Step-by-step explanation: if an hour is divided into quarters it will be in increments of 15 minutes, since one hour is 60 minutes. 60 minutes divided by 5 is 15 minutes.
So 1 hour and 38 minutes is rounded off to 1 hour and 45 minutes.
this is 1 hour + 3/4 hour = 1 3/4 hour. This is same as 1.75 hour
3/4 is .75
speed divided by the time will give the average speed.

Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $20 and same-day tickets cost $35. For one performance,
there were 60 tickets sold in all, and the total amount paid for them was $1500. How many tickets of each type were sold?
Number of advance tickets sold:
Number of same-day tickets sold:
The linear equation 20x + 35(60-x) = 1500 can be solved to find the number of tickets.
What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its related terms in various languages may have somewhat different definitions; for example, in French, an equation is described as including one or more elements, but in English, an equation is any well-formed formula that includes two expressions linked by an equals sign.
Let the number of advance tickets sold = x
And then, the number of same-day tickets sold = 60 - x
Then, the equation formed is
20x + 35(60-x) = 1500
=> 20x + 2100 - 35x = 1500
=> -15x = 1500 - 2100
=> x = -600/ -15 = 40
Hence, the number of advance tickets sold = 40
And the number of same-day tickets sold = 60 - 40 = 20

The formula C=3.14d can be used to approximate the circumference of a circle given its diameter. Company A manufactures and sells a certain washer with an outside circumference of 6 centimeters. The company has decided that a washer whose actual circumference is in the interval 5.8
Solving the circumference function, we have that:
The corresponding interval for diameters of the washers is 1.85 ≤ d ≤ 1.97.
What is the interval of possible values for the diameter?The circumference of a circle of diameter d is given by:
C = 3.14d.
As stated in the problem.
The interval of circumference values is:
5.8 ≤ C ≤ 6.2.
Hence the lowest possible value for the diameter is given by:
3.14d = 5.8
d = 5.8/3.14
d = 1.85.
The highest possible value for the diameter is given by:
3.14d = 6.2
d = 6.2/3.14
d = 1.97.
Then the compound inequality that completes the given sentence is:
1.85 ≤ d ≤ 1.97.
What is the missing information?The interval for the circumference values is given by:
5.8 ≤ C ≤ 6.2.
We have to complete the following sentence with the compound inequality:

The lengths of the side of a triangle are 6, 8, 10. Can the triangle be a right triangle?
Yes, the triangle is a right-angle triangle.
Right angle triangle is a triangle in which one of the angles as 90 degree.
For the triangle to be right angle triangle
perpendicular² + base² = hypotenuse²
The three sides of a triangle are 6, 8 and 10
So,
6² + 8² = 10²
36 + 64 = 100
100 = 100
Therefore the triangle is a right-angle triangle.

With regards to the rigid transformations, Yes, it is true to state that ∠ABD is congruent to ∠EFM. This can be justified by translating ∠ABD by superimposing it on ∠EFM.
It is also true to state that ∠ ABD is congruent to ∠GFHG. To justify this, rotate ∠ABD by 180°
What is a rigid transformation?A rigid transformation in mathematics is a geometric transformation of a Euclidean space that retains the Euclidean distance between each pair of points. Rotations, translations, reflections, and any combination of these are examples of rigid transformations.
Hence, the above statements are true. Note that rigid transformations do not modify the distance angles, size or shape.

Together, Luke and James have never eaten more than 16 pieces of pizza at one time.Which equation describes y, the total number of pieces that Luke has eaten at one time givenx, the number of pieces that James has eaten?a. y <_16-x b. y>_16-x c. y=16-x d. not here
y ≤ 16 - x (option A)
Explanation:let the total number of pieces Luke ate at a time = y
Let the total number of pieces James ate at a time = x
They have never eaten more than 16 pices of pizza
This is written as:
maximum 16 : ≤ 16
number of pieces Luke ate at a time + total number of pieces James ate at a time ≤ 16
y + x ≤ 16
rewritting to make y subject of formula:
y ≤ 16 - x (option A)
Given a || b , and c is not parallel to a or b, which statements must be true? a 1/2 3 / 4 Select each correct answer b . 5/6 7/8 mZ2 = m_7 9/10 C m27 = m_10 11 / 12 mZ8 = m29 m24 = m28
m∠2 = m∠7
and
m∠4 = m∠8
Both are correct answers and should be ticked
Here, we want to select which of the statements must be correct based on the diagram given
a) m∠2 = m∠7
This is correct
m∠2 = m∠3 as they are vertically opposite angles
However, m∠3 = m∠7 as they are vertically opposite angles
b) m∠7 = m∠10
We cannot compare the relationship between b and c as the pair are not parallel lines
c) m∠8 = m∠9
This is not correct also as the pair of lines are not parallel
d) m∠4 = m∠8
These two are corresponding angles, so they are congruent and thus equal in value
