Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.

(05.03 MC)What is the area, in square units, of the polygon shown here?
10 units. 13 units. 15 units. 18 units.
To resolve the proposed issue, an explanation is needed in which the subject is addressed
Answer:
13 square units
Step-by-step explanation:
Look at image attached
Divide shape into two rectangles
Rectangle 1:
width: 2 units
length: 5 - 1 = 4 units
AREA: 2 x 4 = 8 sq. units
Rectangle 2:
width: 1 units
length: 5 units
AREA: 1 x 5 = 5 sq. Units
Combine area of rectangles:
8 + 5 = 13 sq. Units
That is the area of the whole polygon.

at McDonald's, you get a $1 coupon for every 3 fries you buy. What is the least number of fries you could buy in $10 in coupons?
Answer:
You must buy at least 30 fries to get 10 dollar ins coupons
Step-by-step explanation:
We can write a ratio to find the minimum
1 dollar 10 dollars
--------------- = -------------
3 fries x fries
Using cross products
1 *x = 10 * 3
x = 30
You must buy at least 30 fries to get 10 dollar ins coupons
HELP PLEASE! Write an equation with variables on both sides that has a single solution "-1." Explain how to find that solution
ANSWER : HEY MATE
The solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step
Let's create an equation with variables on both sides that has a single solution of "-1."
Let's call the variable "x."
An equation that meets these criteria is:
2x + 3 = x + 2.
We want to isolate the variable "x" on one side of the equation to find the solution.
Start by simplifying both sides of the equation.
On the left side, we have; 2x + 3;
And, on the right side, we have x + 2.
Now solve the equation as;
2x + 3 = x + 2
Subtract x on both sides;
2x - x + 3 = 2
x + 3 = 2
Subtract 3 on both sides;
x = 2 - 3
x = - 1
So, the solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step.

Answer:
90.5
Step-by-step explanation:
Diagonal length of the base = √(8²+8²) = 8√2
height = 8,
so area = 8√2 × 8 (since the diagonal and the height makes the rectangle JFHL
so, 8√2 × 8
= 64√2

i have 30 coins. some of them are dimes, and some of them are quarters. in total, i have $4.05. how many of each coin do i have?
Answer: 23 dimes & 7 quarters
Step-by-step explanation:
Dimes = 10¢ = $0.10Quarters = 25¢ = $0.25Number of dimes = xNumber of quarters = yYou can create two equations:
[tex]\left \{ {{x + y = 30} \atop {0.10x + 0.25y =4.05}} \right.[/tex]
Rearrange x + y = 30:
[tex]y=30-x[/tex]
Substitute it into the x-value of the other equation & solve:
[tex]0.10x + 0.25y =0.10x + 0.25(30-x)=4.05\\0.10x+7.5-0.25x=4.05\\0.10x-0.25x=4.05-7.5\\-0.15x=-3.45\\x=\frac{-3.45}{-0.15} =23[/tex]
With the x-value, substitute it back to the original equation to find y-value:
[tex]y=30-x=30-23=7[/tex]
Therefore, there are 23 dimes & 7 quarters.
There are 23 dimes and 7 quarters.
Given that, the total number of coins=30.
How to convert dimes to dollars?To convert dimes to dollars we need to multiply the number of dimes by 0.1.
Let the number of dimes be x, and then the number of quarters will be 30-x.
Now, x×0.1+(30-x)×0.25=4.05
⇒-0.15x=-3.45
⇒x=23
30-x=7
Hence, there are 23 dimes and 7 quarters.
