Hallie made 12 quarts of homemade yogurt. She put the yogurt in 34-cup containers. How many containers did Hallie fill?

Answers

Answer:

1 container and 14 cups

Step-by-step explanation:

We know that 1 quart = 4 cups

therefore, 12 quart = 48 cups

each container has 34 cups

so one container would be full and remaining 48-34 =14 cups can be filled in another container.

rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, a in seconds, by the given equation. Using this equation, find out
the time at which the rocket will reach its max, to the nearest 100th of a second.
y=16x^2+ +225x+79

Answers

Answer:

7.03 seconds

Step-by-step explanation:

First, you need to differentiate the equation (The derivative of y represents the rocket's velocity):

y' = 32x + 225

Then, set y' to 0 and solve for x

0 = 32x + 225

x = 7.03s

John has four more apples than Kim. Kim has three times as many apples than Rob. Altogether, they have 46 apples. How many apples does each person have?

Answers

Answer:

Step-by-step explanation:

j=k+4

k=3r

j=3r+4

j+k+r=46

3r+4+3r+r=46

7r+4=46

7r=42

r=6, since k=3r

k=18, since j=k+4

j=22

j,k,r=22,18,6

A delivery driver is traveling a total of 250 miles from a warehouse to a store at an average speed of 45 miles per hour. The function f(x)=250-45xf(x)=250−45x represents the distance remaining, in miles, after traveling for xx hours.

Answers

Answer:

115miles

Step-by-step explanation:

Given the function of the distance remaining represented by the function

f(x) =250-45x where;

x is the time taken in hours

Since we are not told what to loom for, we can calculate the distance remaining after 3hrs.

Substitute x =3 into the equation

f(3) = 250-45(3)

f(3) = 250-135

f(3) = 115

Hence the distance remaining after 3 hrs is 115miles

ok so you have to start somewhere right? even if your work has piled up, its better so start now then let it get even worse. that'll also make you feel worse. last semester i let everything pile up without doing a single assignment and i failed all of my classes. my parents and teachers were disappointed, and i used to be an all A student so it was really embarrassing. i wish i could go back in time and do all of my work so i would have free time now.

my point is you'll regret not doing your work, so please do it. you'll have more time to do things you enjoy, and im sure your parents will be proud of you for all the progress you've made. it seems hard right now but i promise it gets easier as you start working. if you get overwhelmed by anything, try telling your family, friends or teacher. they only want the best for you so please don't hesitate to ask them anything!!

The sum of 3 consecutive integers is 30.
What is the third number in this sequence?

Answers

Answer:

Step-by-step explanation:

the 3 numbers are 9, 10, 11

Answer:

Third number = 11

Step-by-step explanation:

Let 3 consecutive numbers be x ,x +1 , x +2

x +x+1 + x+ 2 = 30

x +x +x + 1 + 2 = 30 {Combine like terms}

3x + 3 = 30 {Subtract 3 from both sides}

3x = 30 - 3

3x = 27 {Divide both sides by 3}

x = 27/3

x = 9

Third number =x + 2 = 9 + 2 = 11

Can two obtuse angles be supplementary? Explain why or why not

Answers

Answer:

Step-by-step explanation:

No, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°. It will not satisfy the property of the supplementary angles when we add obtuse angles.

Answer: the answer is No

Step-by-step explanation: the answer is no because, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°. It will not satisfy the property of the supplementary angles when we add obtuse angles.

The value, in dollars, of an antique has increased exponentially over x years as shown in the graph. image What are the domain and range of the function? A. Domain: x ≥ 0 Range: y ≥ 0 B. Domain: x ≥ 0 Range: y ≥ 1,000 C. Domain: all real numbers Range: y ≥ 1,000 D. Domain: all real numbers Range: y ≥ 0

Answers

Answer:

C. Domain: all real numbers Range: y ≥ 1,000

Step-by-step explanation:

0 to 10 years = 50

30 to 40 years = 150

Domain: all real numbers and Range: y ≥ 1,000, which is the correct answer would be an option (C).

What are the domain and range of the function?

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The graph is given in the question.

The value, in dollars, of an antique, has increased exponentially over x years as shown in the given graph.

We have to determine the domain and range of the function.

As per the given graph,

we can see that the values of the x-axis are all real numbers in the graph which means its domain is all real numbers and the value of the y-axis begins at 1000 and continuously increases, therefore this means the range of the function is y ≥ 1,000.

Thus, Domain: all real numbers and Range: y ≥ 1,000.

Hence, the correct answer would be an option (C).

Any help please? (pre-algebra) Please provide an explanation, if not it’s fine but one would be appreciated.

Answers

Answer:

Option C

Step-by-step explanation:

Height of the rocket is modeled by,

h(t) = -16t² + 125t + 24

Height of the rocket in t = 0.1 seconds

h(0.1) = -16(0.1)² + 125(0.1) + 24

= -0.16 + 12.5 + 24

= 36.34 feet

At t = 5 seconds,

h(0.5) = -16(5)² + 125(5) + 24

= -400 + 625 + 24

= 249 feet

At t = 5.6 seconds,

h(5.6) = -16(5.6)²+ 125(5.6) + 24

= -501.76 + 700 + 24

= 222.24 feet

At t = 7.8 seconds,

h(7.8) = -16(7.8)² + 125(7.8) + 24

= -973.44 + 975 + 24

= 25.56 feet

Therefore, change in height is maximum at t = 5.6 seconds

When I requested the new book about my hero, Sherlock Holmes, the library helper's brow furrowed, and his tense lips formed a line like a ruler."I'm afraid that book is no longer available," Victor stated.I stared in disbelief. Turning, I walked towards the new releases section, but most of the shelves were as empty as overturned buckets. Sandra, my sidekick, was hidden behind her pile of books. She updated me on detective gear, handed me a glass of water, and introduced our next assignment. We would be investigating the missing library books. I looked at Sandra, reluctant to investigate books.Just then, Victor pulled up a chair and sat down. Sandra introduced him to me as our client. Victor adjusted his glasses, looked down at the ground, and took a deep breath. He explained that library books were disappearing each night, especially new releases. The only people who had keys were the librarians and the library helpers. The librarians were beginning to blame the library helpers for the missing books, thinking that they weren't locking the library doors properly. This obviously didn't sit well with Victor, and one librarian in particular had him worried. Wilma always stayed until the last minute and left without checking anything out.
