Answer:
The number of quarters in total = 16 quarters
The number dimes = 32 dimes
Step-by-step explanation:
The given information are;
The total amount of money in held = $7.20
The denomination of the money held = Dimes and quarters
The number dimes = 2 × The number of quarters
Given that a dime = 10 cents = $0.1
A dollar = 25 cents = $0.25
Let the number of quarters in the sum of money = X
Therefore, we have;
X × $0.25 + 2 × X × $0.1 = $7.20
X × $0.25 + X × $0.2 = $7.20
X × $0.45 = $7.20
X = $7.20/$0.45 = 16
Therefore, the number of quarters = 16
The number of quarters in total = 16 quarters
The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes
The number dimes = 32 dimes.
When Jake volunteers at the animal shelter, he divides 2/3 cup of cat food equally between 2 cats. How much food does he give each cat?Use the area model

Stephanie uses a ride service to get to different places in her city. If Stephanie uses Uber the service charges 1.50 per mile . If Stephanie uses lift the service charges $2.00 per mile. Let m represent the number of miles traveled. Which of the following statements are true . Select all that apply
Answer:
By a small online search, i found that the actual question seems to be:
"Stephanie uses a ride service to get to different places in her city. If Stephanie uses Uber the service charges $5.00 plus 1.50 per mile . If Stephanie uses lift the service charges $2.00 per mile. Let m represent the number of miles traveled. Which of the following statements are true . Select all that apply"
The statements are not provided, so i will answer it in a general way.
We have two different equations:
1) a fixed amount of $5.00 plus $1.50 for each mile, m.
This is a linear equation:
y1 = $1.50*m + $5.00
2) No fixed amount, only $2.00 for each mile, m.
y2 = $2.00*m
Now, the things we can see are which service will be cheaper as a function of m.
To see this, we can see the difference between y1 and y2.
When the difference is negative, this means that y1 is cheaper.
When the difference is positive this means that y2 is cheaper.
When the difference is zero, both services charge the same.
D = y1 - y2 = $1.50*m + $5.00 - $2.00*m
= (-$0.50)*m + $5.00
First let's find when it is zero.
0 = (-$0.50)*m + $5.00
5.00/0.5 = m = 10
So for 10 miles, both services charge the same.
As the coefficient that multipies m is negative, if we have m > 10, then the difference will be negative.
This means that for m > 10, y1 is cheaper.
Then for m < 10, y2 is cheaper.

The length y of a rectangle is four less than three times the width x. The perimeter of the rectangle is 16 cm.
There is no requirement in the question. I'll calculate the area of the rectangle to help you with this question.
Answer:
[tex]A=15\ cm^2[/tex]
Step-by-step explanation:
System of Equations
Let's call y to the length of a rectangle, x to its width. There are two conditions that will help us to solve for x and y.
The length is four less than three times the width. That is written as:[tex]y=3x-4[/tex]
The perimeter of the rectangle is 16 cm. The equation for this condition is:[tex]2x+2y=16[/tex]
Divide by 2:
[tex]x+y=8[/tex]
To solve the system, we'll substitute the y in the first equation into the second:
[tex]x+3x-4=8[/tex]
Joining like terms:
[tex]4x=8+4[/tex]
Solving:
[tex]x=12/4=3[/tex]
Find the value of y:
[tex]y=3x-4=3*3-4=9-4=5[/tex]
Thus, the length of the rectangle is 5 cm and its width is 3 cm. The area is calculated as:
[tex]A=xy=3\ cm\cdot 5\ cm=15\ cm^2[/tex]
[tex]\boxed{A=15\ cm^2}[/tex]

Use the points (1998,13.60) and (2003,19.00) to write the slope intercept form
Answer:
y=1.08x-2144.24
Step-by-step explanation:
find the slope: m=(19.00-13.60)/(2003-1998)=1.08
so we have y=1.08x +b
next, use the point (2003, 19.00) to find b:
19.00=1.08*2003 +b =>b=-2144.24

Answer:

0 F x>o v 0 cover the interval (-4,-3
The statement which is true about the graphed function is that F(x) > 0 over the interval (-∞, -4).
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given is a graph of a function.
The options contains the open interval (-∞, -3) and (-∞, -4).
It is clear that along this interval, the graph is situated above the X axis.
This means that the values of y is all greater than 0.
At x = -4, F(x) = 0
For all x < -4, F(x) > 0
So the correct statement is F(x) > 0 over the interval (-∞, -4).
Hence F(x) > 0 over the interval (-∞, -4).

If three times a number is increased by twenty-two, the result is fourteen less than seven times the number. Find the number.
Answer:
x = 3.6
Step-by-step:
3 times a number is increased by twenty two = 3x+22
Result ( = ) fourten less than seven times the number = 7x - 14
Since they are equal to each other, you have:
3x + 22 = 7x - 14
Solve:

The sum of John and Dave's ages is 63. Dave is is six years less then twice Johns
age. How old is Dave?
Answer:
The present age of Dave is 40 years
Step-by-step explanation:
Let the present age of Johns be x
We are given that Dave is six years less then twice Johns age.
Dave's present age = 2x-6
We are also given that The sum of John and Dave's ages is 63.
So, [tex]x+2x-6=63[/tex]
[tex]3x-6=63[/tex]
[tex]3x=63+6[/tex]
[tex]3x=69[/tex]
[tex]x=\frac{69}{3}[/tex]
[tex]x=23[/tex]
Dave's present age = 2x-6=2(23)-6=40
Hence The present age of Dave is 40 years
