elane has $7.00 total in dimes and nickels in her coin jar. the number of dimes that elane has is seven less than three times the number of nickels. how many of each coin does elane have
SHOW WORK PLS AND THE EQUATION
Answer:
Let the number of 50p coins be x
and the number of 25p coins be 2x
Therefore,
Value of 50p coins = 50x p
and value of 25p coins = 2 * 25x p
= 50x p
Total value = Rs 34 = 34 * 100 p= 3400p
According to the question,
50x p + 50x p = 3400 p
=100x p = 3400p
= x = 3400p/100p
= x = 34
Therefore , number of 50p coins =34
and , number of 25p coins = 34 * 2 = 68

What is the vertex form of y equals 2 x squared minus 8 x plus 1?
According to the given information, the vertex form is 2(x - 8)² + 1.
What do we mean by vertex form?A quadratic function has the vertex form f(x) = a(x - h)2 + k, where a, h, and k are constants. A vertex form in geometry is a location where two or more curves, lines, or edges converge. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedra. The four corners of a square, for instance, are each referred to as a vertex.So, vertex form:
Vertex form: f(x) = a(x - h)² + kNow, substitute the given values as:
2(x - 8)² + 1Therefore, according to the given information, the vertex form is 2(x - 8)² + 1.

The total amount payable at the end of 4 years is 406
In this given sum we are provided with the values of principal , rate of interest , and the number of years , we are asked to calculate the amount payable after 4 years that is the matured amount which is calculated with the addition of the principal amount and the simple interest. For that we had to first find out the amount of interest and then we need to add that with the principal amount to get the matured amount or the amount that is payable at the end of 4 years.
here we have to apply the formulla of simmple interest :

5. The 50 snakes in the serpentarium include families of 10 vipers, 23 colubrids, 9 elapids, and 8 giant snakes.
Calculate the percent of each type of snake. Use the percent that you find and multiply each times 360° to
find the number of degrees for each sector.
I need help solving the percent and degree
Percent of vipers is 20% and its degree is 72 degrees.
Percent of colubrids is 46% and its degree is 165.60 degrees.
Percent of elapids is 18% and its degree is 64.80 degrees.
Percent of giant snakes is 16% and its degree is 57.60 degrees.
How we do calculate the percent and degree?The percent can be calculated as follows:
Percent of vipers = (Number of vipers / Total number of snakes) * 100 = (10 / 50) * 100 = 0.20 * 100 = 20%
Percent of colubrids = (Number of colubrids / Total number of snakes) * 100 = (23 / 50) * 100 = 0.46 * 100 = 46%
Percent of elapids = (Number of elapids / Total number of snakes) * 100 = (9 / 50) * 100 = 0.18 * 100 = 18%
Percent of giant snakes = (Number of giant snakes / Total number of snakes) * 100 = (8 / 50) * 100 = 0.16 * 100 = 16%
The degrees can be calculated as follows:
Degree of vipers = Percent of vipers * 360 = 20% * 360 = 72 degree
Degree of colubrids = Percent of colubrids * 360 = 46% * 360 = 165.60 degree
Degree of elapids = Percent of elapids* 360 = 18% * 360 = 64.80 degree

Answer:
C. 1889
Step-by-step explanation:
Given fixed weekly costs of $3778 and a variable cost per handle of $1, you want to know how many handles must be produced weekly for sale at $3 each to break even.
Contribution marginThe "contribution margin" of each handle is the difference between its variable cost and its selling price:
$3 -1 = $2
Break evenThe enterprise will break even when the sum of contribution margins is equal to the fixed costs. If h is the number of handles produced and sold, then to break even, we must have ...
2h = 3778
h = 1889
1889 handles must be molded weekly to break even.
__
Additional comment
You get the same result if you write the profit equation and solve for the number of handles that makes profit be zero.
profit = revenue -cost
0 = (3h) -(3778 +1h)
3778 = 2h . . . . . as above
1889 = h

We must locate the third point by applying a method based on a weight average-like formula after finding the coordinates of two points on the Cartesian plane:
P(x, y) = (2 / 7) * A(x, y) + (5 / 7) * B(x, y)
P(x, y) = (2 / 7) * (- 4, 2) + (5 / 7) * (3, - 6)
