Answer:
528 cookies
Step-by-step explanation:
3 hours is 180 minutes
55 minutes - the 15 for preheating is 40 minutes
180 minutes + 40 minutes = 220 (total time she could've had cookies in the oven)
220 divided by 20 is 11 (total batches of cookies)
11 times 48 is 528
Sorry if my answer is confusing lol
The total number of cookies that Amy baked is 528 cookies.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
To solve this problem, we need to convert the total time the oven was on (3 hours and 55 minutes) into minutes.
Since there are 60 minutes in an hour, the total time the oven was on in minutes is : 3 hours x 60 minutes/hour + 55 minutes = 235 minutes.
We need to subtract the time the oven was preheating (15 minutes) from the total time the oven was on to get the time that was spent baking cookies. This gives us a total of 235 minutes - 15 minutes = 220 minutes of baking time.
Since each batch of cookies takes 20 minutes to bake, the number of batches of cookies that Amy baked is :
220 minutes / 20 minutes/batch = 11 batches.
Since each batch contains 48 cookies,
So, the total number of cookies that Amy baked is :
11 batches × 48 cookies/batch = 528 cookies.
Thus, Amy baked 528 cookies overall altogether.

Explanation:
The multiplicative inverse of x is 1/x, and vice versa. This is true as long as x is not 0.
The multiplicative inverse of 1/5 is 5. These two values multiply to 1. This is true of any multiplicative inverse pairing.
----------
What we need to do is multiply 5 with (2x-1/5)
Use the distributive property to get the following
5*(2x-1/5)
5*(2x) - 5*(1/5)
10x - 5/5
10x - 1
I multiplied the outer 5 by each term inside (the 2x and 1/5) and simplified.

At the King School, 55% of the students take a bus to school. If 220 students take a bus to school, how many students are there in total?
Answer:
400 student
55/100 * x(unknown) = 220
55x/100 =220
CROSS MULTIPLY
55X = 22000
X = 22000/55
X = 400
The total number of students at the King School is 440.
Given that, at the King School, 55% of the students take a bus to school.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the total number of students be x
So, 55% of x =220
⇒ 55/10 ×x=220
⇒ 0.55x=220
⇒ x=220/0.55
⇒ x=440
Therefore, the total number of students at the King School is 440.

An ammonia and water mixture fills a five-gallon container. Eighty percent of the mixture is ammonia, but some of the mixture will be drained and replaced with pure water. If a five-gallon mixture of fifty percent ammonia is desired, how many quarts of the mixture need to be drained before the water is added, given that 4 quarts equals a gallon
Answer:
The volume of the 80% ammonia that is to be drained before water is added is 7.5 quartz
Step-by-step explanation:
The volume of the ammonia and water mixture = 5 gallons
The percentage of ammonia in the mixture = 80%
The volume of ammonia desired = 5 gallons
The percentage concentration of ammonia desired = 50%
The diluting solution = Pure water
The measure of 4 quarts = 1 gallon
Therefore, we have, by equivalence solutions;
80% × x gallon = 50% × 5 gallons
x gallon = 50% × 5 gallons/(80%) = 3.125 gallons
x = 3.125 gallons
The volume of the 80% ammonia that is to be drained = 5 gallons - 3.125 gallons = 1.875 gallons
4 quarts = 1 gallon
1 gallon = 4 quarts
∴ 1.875 gallons = 4 × 1.875 quartz = 7.5 quartz
The volume of the 80% ammonia that is to be drained before water is added = 7.5 quartz
Answer:
7.5

Step-by-step explanation:
In a right triangle, the sum of the squares of the
lengths of the legs is equal to the square of the length
of the hypotenuse. The length of the hypotenuse is 16
and the lengths of the legs are 4 and x.

A train leaves the station at time = 0. Traveling at a constant speed, the train travels 330 kilometers in 3 hours. Answers parts a and b. A. Write a function that relates the distance traveled d to time t. The function that relates the distance traveled d to the time is.
Answer:
The function that relates the distance traveled d to the time t is
f(t) = 110t, where d = f(t)
Step-by-step explanation:
From the question, we were told that the train is At a constant speed, the train travels 330 kilometers in 3 hours
We were told to write function that relates the distance traveled d to the time t, we can do this by writing a linear equation with those functions
Since we are told that the train travels 330 kilometers in 3 hours, then we can say the train travel (330/3) kilometers in 1 hour which means it travel 110 kilometers in 1 hour
Then d= 110t---------------eqn(1)
If if t = 0, then d = 0, as well since at t=0 the train is at the station
At t = 1 then d = 110.
From equation (1) d can be replaced by f(t) then we have
f(t) = 110t----------------eqn(2)
Now we replace d by f (t), because d = f t):
f(t) = 120t
Therefore, The function that relates the distance traveled d to the time is f(t) = 120t

In 2006 the average ticket price for a national football league game was 62.38. Since then the cost has increased an average of $2.54 per year. Write a linear equation to represent the cost of C of an NFL ticket y years after 2006.
Answer:
y = 2.54x + 62.38
Step-by-step explanation:
Let x represent the duration or stipulated years after the year 2006
Let y represent the amount of ticket that is sold
Let m represent the average increase in the price every year
y = mx + c
y = 2.54 × x + 62.38
y = 2.54x + 62.38
Answer:
C=2.54y+62.38
c=2.54y+62.38
C=62.38+2.54y
or
c=62.38+2.54y
