Alita received 24 dollars and 25 cents ($24.25) as change at the grocery store.
For given question,
Alita received twenty-two dollars, seven quarters, and five dimes as change at the grocery store.
The value of coins is all counted in cents.
1 Penny = 1 cent
1 Nickel = 5 cents
1 Dime = 10 cents
1 Quarter = 25 cents
And 1 Dollar = 100 cents
Alita received seven quarters, and five dimes coins as change at the grocery store.
seven quarters = (7 × 25) cents
= 175 cents
five dimes = (5 × 10) cents
= 50 cents
The total coins are:
seven quarters, and five dimes
= 175 + 50 cents
= 225 cents
Now we add all change together.
twenty-two dollars, seven quarters, and five dimes
= 22 dollars + 225 cents
= 22 dollars + 2.25 dollars
= 24.25 dollars
= $24.25
Therefore, Alita received 24 dollars and 25 cents ($24.25) as change at the grocery store.

the cost of a can of coca-cola in 1960 was $ 0.10 . the function that models the cost of a coca-cola by year is c ( t )
The cost of the Coca-Cola can will be $1 in the year 2000.
Given that the cost of a can of Coca-Cola can in 1960 = $0.10
The function which models the cost of a Coca-Cola by year 't' is
c(t) = [tex]0.10e^{0.0576t}[/tex].
Here, 't' denotes the number of years since 1960.
c(t) is an exponential function.
We have to find the year in which the cost of a can will be $1.
So substitute c(t) = 1, we get,
1 = [tex]0.10e^{0.0576t}[/tex]
⇒ [tex]10 = e^{0.0576t}[/tex]
We have, [tex]ln(e^x) = x[/tex] .
Taking logarithm on both sides, we get,
log(10) = 0.0576t
⇒ [tex]t=\frac{ln(10)}{0.0576}[/tex] = 39.97 ≈ 40 years .
Thus the cost of a can of Coca-Cola will be $1 in the year, 1960 + 40 = 2000.

What is the slope of the line that passes through the points (-7, -2) and
(-2, -22)? Write your answer in simplest form.
Answer:
m = -4
Step-by-step explanation:
We are given the points (-7, -2) and (-2, -22), and we want to write the slope of the line.
The slope (m) can be calculated from two points using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.
We already have everything we need to calculate the slope, however, let's label their values to help avoid any confusion and mistakes for later.
[tex]x_1=-7\\y_1=-2\\x_2=-2\\y_2=-22[/tex]
Now, substitute these values into the formula. Remember that the formula has subtraction, and we're dealing with negative numbers here.
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-22--2}{-2--7}[/tex]
Simplify.
m=[tex]\frac{-22+2}{-2+7}[/tex]
Add.
m=[tex]\frac{-20}{5}[/tex]
Divide.
m = -4
The slope of the line is -4.

jackie has a checking account. For each day that her checking account balance falls below zero, she is charged by the bank a fee of $7.50 per day. Her current balance in the account is –$12.50. If she does not make any deposits or withdrawals, what will be the new balance in her account after 2 days? Show your work.
The new balance will be -27.50.
How to illustrate the expression?It should be noted that for each day that her checking account balance falls below zero, she is charged by the bank a fee of $7.50 per day.
Since her current balance in the account is –$12.50, the new balance after 2 days will be:
= -12.50 + (-7.50 × 2)
= -12.50 + -15
= -27.50

Answer:
16,300,000 viewers
Step-by-step explanation:
We have two ordered pairs and we can write an equation in the slope intercept form of the line from the information that we have.
y = mx + b y is the number of viewers and x in the number of minutes of ads.
m is the slope. That is the change in y over the change in x. We will use the two points given to find this.
(14, 10,000,000) (25, 17,000,000)
slope:
[tex]\frac{y{1}- y{2} }{x_{1}-x_{2} }[/tex] = [tex]\frac{17,000,000 - 10,000,000}{25-15}[/tex] =[tex]\frac{7,000,000}{10}[/tex] = 700,000
Now we need the b or the y-intercept. We will use the slope and one of the points to find this. We could use either point. I am going to use the point (15, 10,000,000)
y = mx + b
I will use 10,000,000 for y
I will use 15 for x
I will use 700,000 for the slope.
I will plug these numbers in and solve for b
10,000,000 = 700,000(15) + b
10,000,000 = 10,500,000 + b Subtract 10,500,000 from both sides
-500,000 = b
Now we can write the equation
y = mx + b
y = 700,000x -500,000 Plug is the 24 for x to solve for the number of views.
y = 700,000(24) -500,000
y = 16,800,000 - 500,000
y = 16,300,000

what are the probabilities that the three subsystems, as well as the entire system, are operational?
Three subsystems are reliability-wise in series and make up a system. Subsystem 1 has a reliability of 99.5%, subsystem 2 has a reliability of 98.7% and subsystem 3 has a reliability of 97.3% for a mission of 100 hours.
We suppose that the system consists of one operating series subsystem, an identical stand-by subsystem, and a switch. Each subsystem consists of N components.
When the operating subsystem fails, the spare is put in motion by the switch immediately. The failed subsystem is restoring or changing the failed component. Because of the memoryless property of the exponential distribution of components lifetime, the renewal of a failed element means the renewal of the whole subsystem. We assume that there is a single repair facility. A renewal time is a random variable having distribution depending on a failed component. We suppose that the lengths of restoring periods of components are represented by identical copies of nonnegative random variables.

Arithmetic operations follow the rule of BODMAS where
B represents brackets, O represents orders of powers or roots, D represents division, M represents multiplication,A represents addition and S represents subtractionHow to insert parentheses in the appropriate places:
1. How to insert parentheses in the appropriate places in 8 + 3 - 2 × 9 = 17Since the expression evaluates to 17, we put a parentheses between 3 and - 2. So,
8 + (3 - 2) × 9 = 8 + 1 × 9
= 8 + 9
= 17
So, the correct arithmetic operation with parentheses is 8 + (3 - 2) × 9 = 17
2. How to insert parentheses in the appropriate places in 28 ÷ 4 + 3 × 4 + 3 = 28Since the expression evaluates to 28, we a parentheses between 4 and + 3. So,
28 ÷ 4 + 3 × 4 + 3 = 28 ÷ (4 + 3) × (4 + 3)
= 28 ÷ 7 × (4 + 3)
= 4 × 7
= 28
So, the correct arithmetic operation with parentheses is 28 ÷ (4 + 3) × (4 + 3) = 28
3. How to insert parentheses in the appropriate places in 5 × 3 + 2 × 6 ÷ 3 = 50Since the expression evaluates to 50, we put a parentheses between 3 and + 2. So,
