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.

Rob is saving money for a down payment on a house. He opens a savings account at his local bank and deposits $1000. He models his savings plan with the equation y=400x+1000
based on his current income and monthly savings rate. What is the meaning of the y-intercept in the equation?
Answer:
x=-5/2
Step-by-step explanation
y=0
0=400x=1000 divide both sides
x=-5/2
Answer:
The Answer is D: Starting amount in his savings account
Step-by-step explanation:
The y-intercept represents the starting amount in his savings account.
x = 0 for the y-intercept.
y = 400x + 1000
y = 400(0) + 1000
y = 1000

lim x tends to π÷2 , then what is the value of (tanx + cotx) ÷ ( tanx - cotx)
(tan(x) + cot(x)) / (tan(x) - cot(x)) = (tan²(x) + 1) / (tan²(x) - 1)
… = (sin²(x) + cos²(x)) / (sin²(x) - cos²(x))
… = -1/cos(2x)
Then as x approaches π/2, the limit is -1/cos(2•π/2) = -sec(π) = 1.

How do the values compare? Order the values from least to greatest. -1 1/4 , |-1 3/4-| , 3/4 , -2 1/4 , |1 1/4-| , and |-2 1/4|
Answer:
[tex]-2 \frac{1}{4}<-1 \frac{1}{4} < \frac{3}{4}< |1 \frac{1}{4}|< |-1 \frac{3}{4}| < |-2 \frac{1}{4}|[/tex]
Step-by-step explanation:
Given the numbers:
[tex]-1 \frac{1}{4} , |-1 \frac{3}{4}| , \frac{3}{4} , -2 \frac{1}{4} , |1 \frac{1}{4}| , and |-2 \frac{1}{4}|[/tex]
To find:
The ascending order of the given numbers.
Solution:
First of all, let us have a look at the definition of absolute value function i.e. Modulus function.
[tex]|y|=\left \{ {-{y}\ if\ y<0 \atop {y}\ if\ y>0} \right.[/tex]
i.e. if the numbers is negative, then a negative sign is added to make the number positive.
Now, let us have a look at the given numbers with modulus one by one.
[tex]|-1 \frac{3}{4}| = -(-1 \frac{3}{4})=1 \frac{3}{4}\\ |1 \frac{1}{4}| = 1 \frac{1}{4}\\|-2 \frac{1}{4}| = -(-2 \frac{1}{4})=2 \frac{1}{4}[/tex]
Smallest numbers are with negative signs.
And negative numbers with larger magnitude are smaller.
Therefore, the ascending order will be:
[tex]-2 \frac{1}{4}<-1 \frac{1}{4} < \frac{3}{4}< |1 \frac{1}{4}|< |-1 \frac{3}{4}| < |-2 \frac{1}{4}|[/tex]

A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 119 pounds requires 136 milligrams of medicine
What is the weight of a patient who requires 200 milligrams of medicine?
Answer:
228.571428 or estimate it down
Step-by-step explanation:
136 ÷ 119 = 1.14285714
1.14285714 x 200 = 228.571428
The weight of the patient who required 200 mg of medicine is 175 pounds.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 5 is an equation.
We have,
Amount of medicine = Patient's body weight.
136 mg = 119 pounds
Multiply 200/136 on both sides.
200 mg = 200/136 x 119 pounds
200 mg = 175 pounds
Thus,
The weight of the patient who required 200 mg of medicine is 175 pounds.
