Jaime has $2. 60 in dimes and nickels. The number of dimes is 14 more than the number of nickels. How many of each coin does he have?.
Dime is one-tenth of a dollar, while nickle is one-twentieth part of a dollar. Jaime has got 22 dimes and 4 nickle coin in this case.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For the given case, since number of dimes is given in terms of number of nickels, so lets assume that:
Number of nickle Jaime got = [tex]x[/tex]Number of dime Jaime got = 14 more than the number of nickle = [tex]14 +x[/tex]Since 1 nickle's cost = $0.05,
thus, x nickles' cost = [tex]x \times 0.05[/tex] (in dollars)
And as 1 dime's cost = $0.10,
thus, 14 + x dimes' cost = [tex]0.10 \times (14 + x)[/tex] (in dollars)
Total amount Jamie have = Amount by nickles + Amount by dimes
Total amount Jamie have = [tex]0.10(14+x) + 0.05x[/tex] (in dollars) = $2.60 (as given in the problem)
Thus, we get:
[tex]0.10 (14+x) + 0.05x = 2.60\\1.4 + 0.10x + 0.05x = 2.60\\\\\text{Subtracting 1.4 from both the sides}\\\\0.15x = 1.2\\\text{Dividing both the sides by 0.15}\\\\\dfrac{0.15x}{0.15} = \dfrac{1.2}{0.15}\\\\x = 8\\[/tex]
Thus, Jamie got x = 8 nickles.
And number of dimes he got = x + 14 = 8 + 14 = 22
Thus, Jaime has got 22 dimes and 4 nickle coin in this case.

what is the area of this trapezoid. Enter your answer in the box.
Answer:
[tex]352\ ft ^2[/tex]
Step-by-step explanation:
The formula for the area of a trapezoid is:
[tex]A=\frac{b_1+b_2}{2}*h[/tex]
In this case [tex]b_1 b_2[/tex] represent the two bases of the trapezoid.
We can plug in the given lengths into the equation:
[tex]A=\frac{13+31}{2}*16=\frac{44}{2}*16=22*16=352\ ft^2[/tex]
Answer:
352 ft
Step-by-step explanation:
to do area of a trapezoid you do: (a+b) *h/ 2
a would be 13 b would b 31 and h would be 16 : (13+31) * 16/2
now you will have 44*16/2
now you have 704/2
your final answer is 352

Kathy saves $1 on the first day, $2 on the second day, $3 on the third day and so
on, saving an extra $1 on each subsequent day. On which day will she have over
$100 in total?
Answer:
3 moths and 10 days
Step-by-step explanation:
on each day she gets 1$ that means
1 month = 30 days
e.g. 3 6 9 30 60 90
means 90 days if we add also 1 month it will be 120 days
so 90 + 10 = 100
thats why 3 months and 10 day :)

1. Daniel is working on a project for his math class. He is working with the rational
parent function. He wants to write a rule that will make the graph vertically
stretched, reflect it over the x-axis, and shift the graph down. Which of the
following would meet Daniel's needs?
Using translation concepts, it is found that the function that would meet Daniel's needs is:
g(x) = -cf(x) - b, c > 1, b > 0
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent function is f(x).
The transformations are as follows:
Vertical stretch, hence the function has to be multiplied by a constant c that is greater than 1, that is, [tex]g(x) = cf(x), c > 1[/tex].Reflection over the x-axis, hence the function is multiplied by -1, that is, [tex]g(x) = -cf(x), c > 1[/tex].Shift down, hence a constant b is subtracted from the graph, that is, [tex]g(x) = -cf(x) - b, c > 1, b > 0[/tex].You can learn more about translation concepts at https://brainly.com/question/21197885

1/3rd part of the length of a bamboo is coloured with red and 1/5th part of it is coloured with green and the remaining is 14m is coloured with yellow.[tex]\bold{\underline{ To \: Find :- }}[/tex]
We have to find the total length of the bamboo[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]

According to the question,
[tex]\sf{\dfrac{ 1}{3}}{\sf{x +}}{\sf{\dfrac{ 1}{5}}}{\sf{x + 14 = x }}[/tex]
[tex]\sf{\dfrac{ 1}{3}}{\sf{x + }}{\sf{\dfrac{1}{5}}}{\sf{x = x - 14 }}[/tex]
[tex]\sf{\dfrac{5x + 3x}{15}}{\sf{ = x - 14 }}[/tex]
[tex]\sf{ 5x + 3x = 15( x - 14 )}[/tex]
[tex]\sf{ 8x = 15x - 210 }[/tex]
[tex]\sf{ 210 = 15x - 8x}[/tex]

Hence, The total length of the bamboo is 30m.
Maggie is buying 2 shirts that cost $8. 50 each. There is a 6. 5% sales tax. What is the total Maggie will pay for the shirts? Enter your answer in the box.
The total cost of the two shirt Maggie will pay after including the sales tax is $18.105.
What is cost price per ounce?The cost price per unit is the amount of money required to buy one unit of a brand or goods.
To find the cost price per unit, divide the total amount of cost of the goods to the total number of goods.
The cost of one shirt bought by the Maggie is $8. 50 each. Thus, the cost of the 2 shirts is,
[tex]C=2\times8.50\\C=17[/tex]
Thus, the total cost of the two shirts is $17.
Now, there is a 6. 5% sales tax on the selling price. Thus, the cost of the 2 shirts after the sales tax is,
[tex]C=17+17\dfrac{6.5}{100}\\C=17+1.105\\C=18.105[/tex]
Hence, the total cost of the two shirt Maggie will pay after including the sales tax is $18.105.
