Answer:

Miranda can bake 30 cookies with 6 scoops of flour.

Step-by-step explanation:

The rate is 5 cookies for every scoop of flour. to figure this out we need to divide 15 by three, to get 5, so the rate ends up being 5:1

Next, to find out the number of cookies, we need to multiply 5 by 6 to get 30. Therefore, Miranda can bake 30 cookies.

Answer:

49,800,000 is the answer

Answer:

50,000,000

Step-by-step explanation: What you would do is if you have to round up, remember this way to always get it right. 4 or below = stays the same 5 or above = rounds up. so 49,815,662. Well we would take the 8 and round it up to the 9 making it 10 so 49 turns into 50.

Answer: A

Step-by-step explanation:

Car B was 10 miles east of car A.

The rate of change of position of an object in any direction is called speed.

[tex]speed = \frac{distance}{time}[/tex]

According to the given question

Speed of car A was 60 miles/hour.

⇒ After 2hours the distance covered by car A = 60 × 2 = 120 miles.

But it is given that car travelled total 130 miles.

So, the extra distance covered by the car = 130 - 120 = 10 miles.

From the graph we can say that the distance.

At, Time = 0

The distance travelled by car B is 20 miles.

Now, the extra distance covered by the car A w.r.t B = 20 - 10 = 10 miles

Since, both the cars were travelling in east direction.

Therefore, Car B was 10 miles east of car A.

Answer:

438,800,000

Step-by-step explanation:

The number 438 million comes first, so put 438 and then a comma.

The number 800 thousand is next, so put 800 and then a comma.

There is no number for the hundreds, tens, and ones place, so put 000 with no comma after, like this.

Answer:

this is a Sin(), Cos() and Tan()  function  problem.   use the Mnemonic  (new-monic)  SOH CAH TOA  (soo caw tow ah ) to remember which function  sin() cos()  or tan() to use.. :) these types of problems are pretty confusing, Use that Mnemonic to keep the functions in order

Step-by-step explanation:

since we know the distance to the tree.. and we know the angle and we have a formula  TOA to figure out the one pieces of info we don't know ...  use TOA  that tells us our formula..  TOA(Ф)=Opp /  Adj     where  Tan(Ф) is using Ф= to our angle of 32 degrees ( remember Ф can be in degrees or radians, its in degrees for this problem) Adj = the Adjacent side of the triangle from the known angle.. the 32 degree angle ,  Opp = the Opposite side of the triangle formed by the imaginary lines from Kari to the base of the tree and from Kari to the top of the tree..   and then the tree , from it's base to it's top... we know the angle and the Adj side of that triangle so we can figure out that last part of TOA  by saying  Tan(Ф)=Opp/ Adj .... or say  Tan(32)= Opp / Adj    ⇒ Tan(32)=Opp / 90 ⇒ Tan(32) *90 = Opp   this will be the height from the ground to the top of the tree..  but.. the tree is at an angle , keep in mind... sooo  Tan(32)*90=56.238 feet  now take the new triangle that we know one side to... from the ground to the height of the tree..  in a vertical line from the ground to a point at 56.238 feet .. that is the Adj side of this new triangle.. the tree is on the Hypotenuse of this new trialge,  which we want to find. we know the Adj side we know the angle to find the Hypotenuse use CAH , from our Mnemonic at the top,  the Mnemonic is really important b/c keeping track of which part goes where in the triangles is pretty confusing.  Cos(5)=Adj / Hyp  ⇒ Cos(5)=56.238 / Hyp ⇒56.238 / Cos(5)= Hyp   = 56.453 feet  :)  that's how tall that tree is , lets chop it down :P and blame it on George Washington  :P  The tree, to the nearest 10th of a foot, is 56.5 feet

Answer:

45 pages

Step-by-step explanation:

The unit rate is  the number of pages divided by the unit of time

10 pages /2 hours

5 pages per hour

To find the total number of pages of notes take, multiply the unit rate by the total amount of time

We have 9 hours

5 pages per hour * 9 hours

45 pages

Answer:

take x to be the no. of pages for 9 hours

10 pages                      2 hours

x pages                         9 hours

Cross multiplication:

90 = 2x

x = 90/2

x = 45

Answer:

y = (x - 2)(x + 1)(x + 3)

Step-by-step explanation:

horizontal intercepts at x = 2, -1, -3

->  y = 0 when x = 2, x = -1, and x = -3

Think x minus what equals y?

1. y is 0 and x is 2 -> 0 = (2 - 2) -> y = (x - 2)

2. y is 0 and x is -1 -> 0 = (-1 - (-1)) -> y = (x + 1)

3. y is 0 and x is -3 -> 0 = (-3 - (-3)) -> y = (x - 3)

so the equation is y = (x - 2)(x + 1)(x + 3)

since y = 0 when x = 2, x = -1, and x = -3

We want to find a polynomial given that we know its roots.

We will get:

p(x) = x^3 + 2*x^2 - 5*x - 6

-------------------------------------

A polynomial with the roots {x₁, x₂, ..., xₙ} and a leading coefficient A, we can write it as:

p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)

Here we know that the roots (horizontal intercepts) are {2, -1 , -3} but we do not know the leading coefficient, so we will use A = 1.

Then the polynomial is:

p(x) = (x - 2)*(x + 1)*(x + 3)

Expanding that we get:

p(x) = (x^2 - x - 2)*(x + 3)

p(x) = x^3 + 2*x^2 - 5*x - 6

This is a possible equation for the polynomial with the given horizontal intercepts.

Step-by-step explanation:

A. The domain is all of the possible x values (the range is all of the y values)

B. By finding the x value of 4 you can then trace it up until it intersects with the slope or your data points. Then you look left and see which y-value is associated with the x-value.

Answer:

is it multiple choice? is 6x -24 an option?

==================================================

The graphs cross at this point. Intersection points are solutions to systems of equations.

Put another way, (1,4) is on the blue line and on the red line simultaneously.

A point on the red line is a solution to the red equation. A point on the blue line is a solution to the blue equation.

-----------------

Checking the answer:

y = x+3

4 = 1+3 ... plug in x = 1 and y = 4 into the blue equation

4 = 4 .... solution works for the blue equation

y = 3x+1

4 = 3(1)+1 ... plug in x = 1 and y = 4 into the red equation

4 = 3+1

4 = 4 ... solution also works for the red equation

This fully confirms the solution

Answer:

[tex]f(g(2))=10[/tex]

Step-by-step explanation:

We have the two functions: [tex]f(x)=3x-5[/tex] and [tex]g(x)=2+\frac{6}{x}[/tex].

We want to find [tex]f(g(2))[/tex].

So, let's use the second function to find [tex]g(2)[/tex] first:

[tex]g(2)=2+\frac{6}{2}[/tex]

Divide:

[tex]g(2)=2+3[/tex]

Add:

[tex]g(2)=5[/tex]

Therefore, our expression is the same to [tex]f(g(2))=f(5)[/tex].

Now, we can substitute 5 for f(x). This yields:

[tex]f(5)=3(5)-5[/tex]

Multiply:

[tex]f(5)=15-5[/tex]

Subtract:

[tex]f(5)=10[/tex]

So:

[tex]f(g(2))=10[/tex]

And we're done!
