Answers

Answer 1

Answer: We should multiply 4 and 7 to find the LCM.
So the LCM will be 4*7 = 28
If it helped please mark as the brainliest answer.

Answer 2

Answer:

Answer:this is answer is 28

Step-by-step explanation: because lcm stand for least common multiple

so 4 and 7 and have many common factor

how the multiple that’s not always there is 28, which is 4x7=28

Peter wants to buy a coat that costs $87 at full price.The coat is now on sale for 40% offPart A: Explain how Peter can use the fact that 10% of $87 is $8.70 to find the amount he will save on the coat

Part B: Use the same method to find the amount Peter would save on a $64 coat that is on sale for 40% off

Answers

Step-by-step explanation:

Hello!

Part A

Peter can use the fact that 10% of 87 is 8.70 to find the amount he would save because 40% is just 4 times bigger than 10% so he can take 8.70 from to total of the coat 4 times to find out how much it cost.

Part B

Using the same method we know that 10% of 64 is 6.40 so we subtract that from the price of the coat 4 times to find out how much it cost

64 - 6.40 = 57.6

57.6 - 6.40 = 51.2

51.2 - 6.40 = 44.8

44.8 - 6.40 - 38.4

The price of the coat is $38.4

Hope this helps!

Write down a number you can square to give an answer bigger than 400 but smaller than 500

Answers

If you would like to know a number you can square and the answer is bigger than 400 but smaller than 500, you can calculate this using the following step:

20^2 = 400 < 21^2 = 441 < 22^2 = 484 < 500

Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove at a constant speed to get to the safe zone that was 160160 meters away. After 33 seconds of driving, she was 8585 meters away from the safe zone. Let D(t)D(t) denote the distance to the safe zone DD (measured in meters) as a function of time tt (measured in seconds). Write the function's formula.

Answers

Answer: The required function formula is,

D(t) = 160 - 25 t

Step-by-step explanation:

Given,

The total distance of her from the safe zone = 160 meters,

And, after 3 seconds she is 85 meters far away from the safe zone,

Thus, the total distance she covered in 3 seconds = 160 - 85 = 75 meters,

Since, she drove at a constant speed,

Also,

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\implies \text{Her speed}=(75)/(3)=25\text{ km/h}$

Thus, the distance she will cover in t seconds = 25 t

( Because, Distance = Speed × Time )

Hence, the total distance of her from the safe zone after t seconds, D(t) = 160 - 25t

Which is the required function formula.

Kayden drives at a constant speed. The function D(t) can be represented as $D(t)=160-25t$ .

Given information:

Kayden is a stunt driver.

Total distance of safe zone is 160 m.

She drove with a constant speed.

After 3 seconds of driving, she was 85 meters away from the safe zone.

So, the distance traveled in 3 seconds will be 160-85=75 m.

Now, the speed of the driver will be,

$s=(distance)/(time)\ns=(75)/(3)\ns=25 \rm\; m/s$

The distance traveled in t seconds will be 25t.

So, the equation representing the given condition will be,

$D(t)=160-25t$

Therefore, the function D(t) can be represented as $D(t)=160-25t$ .

An athlete eats 75g of protein per day while training. How much protein will she eat during 23 days of training? Write your answer in kilograms.

Answers

K ⇒ Kilograms
H
D
B ⇒ grams
D
C
M
75 ×23= 1725
distance between Kilo. and grams is 3 jumps
so you jump the decimal 3 jumps to the left
Answer: 1.725 Kilograms of protein

You multiply 75 by 23 to get 1725 and since a kilogram has 1000 grams in it, the athlete eats 1.725 kg of protein.

Molly is on a game show. To win $1,000,000, she must answer this question: What key features are necessary—and how are the features used—to create the sketch of a polynomial function? What is Molly's winning answer? Explain in complete sentences.

Answers

- Find the y-intercept
- Find the roots (i.e. x - intercepts)
- Determine where the function increases and where it increases, along with the maximum and minimum values.
- Determine where the function changes concavity along with the inflection points.
- Determine the special points, where the value of the function is not defined and try to find the limit when the value of x approachs to this values
- Determine the limits of the function when x approachs to positive infinity and negative infinity

- For some of those steps you need to know some concepts of calculus: limits and derivatives along with the rules that let you know if a point is a maximum, a minimum or an inflection point.

With that information you can sketch a polynomial function.
