Number of 25 cents coins is 80 and number of 50 cents coins is 20.
Step-by-step explanation:
Given,
A bag contains of total value $ 30.
Number of 25 cent coins is four times that of 50 cent coins.
To find number of 25 cents coin is x
Number of 50 cents coin is y
According to the problem,
[tex]\frac{x}{4} +\frac{y}{2} = 30[/tex] ----- eq 1
x = 4y------ eq 2
Now, we will solve these two equation.
Putting the values of x = 4y in eq 1 we get,
[tex]\frac{4y}{4} +\frac{y}{2} = 30[/tex]
or, [tex]y +\frac{y}{2} = 30[/tex]
or, [tex]\frac{3y}{2}[/tex] = 30
or, y = 20
So, x = 4×20 = 80
Hence,
Number of 25 cents coins = 80 and number of 50 cents coins = 20
Answer:
Step-by-step explanation:
Let 25 cent coin be A and 50 cent coin be B
Given
Total value of 25 cents coin and 50cents coin is $30
That’s
25A + 50B = 30
Also, 25 cents coin is equal to four times that of 50
So,
A = 4B
We now have
25A + 50B = 30
A = 4B
Substitute 4B for A into the first equation
25(4B) + 50B = 30
25 x 4B + 50B = 30
100B + 50B = 30
150B = 30
Divide both sides by 150 to isolate B
150B/150 = 30/150
B = 1/5
Recall
A = 4B
Therefore
A = 4 x 1/5
= 4/5
Number of 25 cents coin is 4/5 and that of 50 cents coin is 1/5

A guitar shop is offering two deals on their guitars. Each guitar is $50 less than its initial sale price. In addition, customers receive a further discount of $3 off each $5 of the sale price. Write a function that represents the final price of a guitar f(x) with an initial price of x. If a guitars initial price was $200, what would it be with the discount?
Answer:
30 dollar discount
Step-by-step explanation:
Using the discount parameters given, the final sale price function of the guitar would be f(x) = x - 0.6x - 30 and the discount on initial price of $200 would be $90
Let initial price = x
First discount :
$50 off :
f(x) = x - 50Second discount :
$3 off each $5 of sale price
3/5 of sale price = 0.6 × (x - 50)Final discount :
0.6( x - 50) = 0.6x - 30The Final sale price :
f(x) = x - 0.6x - 30
Given an initial price, x = 200
Discount on price :
Final discount = 0.6x - 30
Discount on price of x = 200 :
0.6(200) - 30
120 - 30 = $90
Therefore, the discount on the price is $90

You deposit $300 in a savings account. The account earns 2% simple interest per year. What is the interest and balance earned after 10 years?
Answer:
$365.70
Step-by-step explanation:
The formula to find this is [tex]y = a(1+r)^t\\[/tex]
For this, a is the initial amount, r is the growth rate percentage (but displayed as a decimal), and t is time.
So to solve, you would do
[tex]y = 300(1+0.02)^10\\y = 300(1.02)^10\\y = 365.698325998\\OR\\y = $365.7 in interest[/tex]
y = 4x + 11
y = -2x - 1
Answer:
x = -2, y= 3
Step-by-step explanation:
y = 4x + 11
y = -2x - 1
Because both equations are equal to y, we can set them equal to each other
4x + 11 = -2x - 1
Add 2x to each side
4x+2x +11 = -2x+2x -1
6x +11 = -1
Subtract 11 from each side
6x+11-11=-1-11
6x = -12
Divide each side by 6
6x/6 = -12/6
x = -2
Now we need to find y
y = -2x-1
y = -2(-2)-1
=4-1

Given that the measure of ∠x is 120°, and the measure of ∠y is 60°, find the measure of ∠z.
Answer:
60 degrees
Step-by-step explanation:
angle y is vertically opposite to angle a, (we can call it.)
angle x is supplementary to the other angle inside the triangle, which we can call angle b.
so, angle a is 60 degrees, as vertically opposite angles are equal
angle b is 60 degrees as supplementary angles = 180
based of the sum of angles in a triangle is 180 theorem;
60+60+unknown= 180
so unknown is 60 degrees
What is the distance between the points (4,-2) and (-1,10)?
A. 5 units
B. 6 units
C. 12 units
D. 13 units
Answer:
D. 13 units
Step-by-step explanation:
The distance between the points (4,-2) and (-1,10) is 13 units.
Explanation:To find the distance between two points, we can use the distance formula. The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates of the first point are (4, -2) and the coordinates of the second point are (-1, 10). Plugging these values into the distance formula, we get:
d = sqrt((-1 - 4)^2 + (10 - (-2))^2) = sqrt((-5)^2 + (12)^2) = sqrt(25 + 144) = sqrt(169) = 13 units
Therefore, the distance between the points (4, -2) and (-1, 10) is 13 units.

What integers are plotted on the number line below?
Hey there!
We can see on this number line that each tick mark represents one because every five marks, there is a difference of five.
Two marks to the left of 0 will be 0 minus 2, so -2.
Three marks to the left of -5 will be -5 minus 3, so -8.
Your answer is -8 and -2.
Hope this helps!
Final answer:
The integers that are being referred to are -8 and -2, which are negative whole numbers located on the left side of zero on a number line.
Explanation:
When plotted on the number line, integers represent whole numbers that can be positive, negative, or zero.
To identify the integers that are plotted, one would look for distinct marks or points on the number line that correspond to whole numbers.
Based on the data, we come to the conclusion that the numbers in question are -8 and -2.
The integers plotted on the number line are -8 and -2. The integer -8 is to the left of -2 on the number line.
These two numbers are examples of negative integers, which are located to the left of zero on a standard number line. The understanding of how to read a number line and identify the placement of integers is a key concept in mathematics, which allows for better comprehension of more complex mathematical ideas such as rational numbers, real numbers, and complex numbers.

The sum of two numbers is 38. The smaller number is eight less than the larger number. What are the numbers?
Answer: 15 + 23 =38
So n + n + 8 = 38
which means n + n = 30
and since the n's are the same, you just cut the 30 in 2 equal pieces. 15 and 15.
So n = 15, n + 8 = 23
15 + 23 = 38 :)

What is a circle?A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
Given that, a circle is divided into 4 slices. The slices are arranged into the shape.
So, when we will cut the circle into similar manner, the shape we will get closer to will be a rectangle,
When we will calculate the perimeter and the area of the obtained rectangle, it will be equal to the circle.
Hence, on cutting the circle into more and more slices, its shape will get closer to a rectangle.

Final answer:
When a circle is divided into more and more slices and these slices are rearranged, they approximate a circle more closely. While a hexagon may seem like a closer shape due to the angles of its vertices, the ultimate shape remains a circle.
Explanation:
If a student rearranges the slices from a circle cut into more slices, they would get a shape that approximates a circle more closely as the number of slices increases. As each slice becomes thinner, the perimeter of the rearranged shape starts resembling a smooth curve, which is the characteristic of a circle.
Looking at the angles provided, a triangle has 60° angles, a square has 90° angles, a pentagon has 108° angles, and a hexagon has 120° angles. The figures suggest that a hexagon would be a more favorable shape when arranging slices because the angles of a hexagon (120°) are closer to the 360° of a full circle when divided by an increasing number of slices. However, when arranging the slices, the ultimate shape one gets closer to is the circle itself, irrespective of the polygonal shape intermediate stages may suggest.
