Answer: 8 1/2 cups of flour

Step-by-step explanation:

You can look at this solution as x being the number of batches of biscuits.

1x = 1 batch of biscuits

1x = 3 2/5 cups of flour, or 17/5 cups of flour

We need to make 2 1/2 batches, restated as 5/2 batches.

This can be restated as 5/2x.

To determine our answer, we multiply x by 5/2.

5/2*(1x) = 5/2*(17/5)

5/2x = 85/10

Simplify.

85/10 = 8 5/10 or 8 1/2 cups

8 1/2 cups of flour are needed to make 2 1/2 batches of biscuits.

The number in each of the set of blank boxes is 10

From the first number set of stamps, we see that the sum of each row is;

5 + 5 + 5 + 5 = 20

There are four rows. Thus;

Total sum of set of stamps = 20 + 20 + 20 + 20

Total sum of set of stamps = 80

Now, for the blank set of stamps, we see that there are 8 boxes which are al equal. Now, for this 8 boxes t have same sum as that of the initial set of stamps, it means they must sum up to 80.

If the number in each box is x, then;

8x = 80

x = 80/8

x = 10

Thus, the number in each of the set of blank boxes is 10

Answer:

∠ EBF = 47°

Step-by-step explanation:

since BE bisects ∠ ABF , then

∠ ABE = ∠ EBF = 2(w + 11) = 2w + 22

∠ ABF = ∠ ABE + ∠ EBF ( substitute values )

8w - 6 = 2w + 22 + 2w + 22

8w - 6 = 4w + 44 ( subtract 4w from both sides )

4w - 6 = 44 ( add 6 to both sides )

4w = 50 ( divide both sides by 4 )

w = 12.5

Then

∠ EBF = 2w + 22 = 2(12.5) + 22 = 25 + 22 = 47°

Based on the fact that the shape of the given square is dilated with a scale factor, the result would be the first square with a dimension of 3.

The Dilation is to be with a scale factor of 1/3.

This means that the dimensions on the new shape will be:

= Dimensions on original shape x scale factor

= 9 x 1/3

= 9/3

= 3

Dilation does not change the shape of an object so the result of the Dilation would be the first square with a side measurement of 3.

Step-by-step explanation:

Step 1:Start by setting it up with the divisor 9 on the left side and the dividend 481 on the right side like this:         9⟌481

Step 2:The divisor (9) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:    0    9⟌481

Step 3:Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.     0    9⟌481   0  

Step 4:Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.     0    9⟌481   -0      4  

Step 5:Move down the 2nd digit of the dividend (8) like this:    0    9⟌481   -0      48 

Step 6:The divisor (9) goes into the bottom number (48), 5 time(s). Therefore, put 5 on top:    05   9⟌481   -0      48 

Step 7:Multiply the divisor by the result in the previous step (9 x 5 = 45) and write that answer at the bottom:    05   9⟌481   -0      48     45 

Step 8:Subtract the result in the previous step from the number written above it. (48 - 45 = 3) and write the answer at the bottom.    05   9⟌481   -0      48    -45      3 

Step 9:Move down the last digit of the dividend (1) like this:    05   9⟌481   -0      48    -45      31

Step 10:The divisor (9) goes into the bottom number (31), 3 time(s). Therefore put 3 on top:    053  9⟌481   -0      48    -45      31

Step 11:Multiply the divisor by the result in the previous step (9 x 3 = 27) and write the answer at the bottom:    053  9⟌481   -0      48    -45      31     27

Step 12:Subtract the result in the previous step from the number written above it. (31 - 27 = 4) and write the answer at the bottom.    053  9⟌481   -0      48    -45      31   - 27      4

You are done, because there are no more digits to move down from the dividend.The answer is the top number and the remainder is the bottom number.Therefore, the answer to 481 divided by 9 calculated using Long Division is: 53 4 Remainder

Answer:

Omar can ride the roller coaster 4 times and will have 4 tickets leftover.

Step-by-step explanation:

For a more simple problem like this, long division is not necessary.

You may have learned the technique of finding how many times a divisor can "go in" to the dividend.

In this case, 5 (the cost of riding the coaster) can go into 24 (the amount Omar has) 4 times, because 5, 10, 15, 20. However, going in one more time puts us at 25, which Omar does not have, so 5 can only go into 24 5 times.

Since there is still 4 tickets leftover, Omar can ride the coaster 4 times, and will have 4 tickets left.

Answer:

  17 bars

Step-by-step explanation:

Peter wants to compute the maximum number of bars he can load safely if the load limit of 1200 kg and the bar weight of 60 kg are each rounded to the number of significant digits those numbers have.

The error in a rounded number is assumed to be as much as half of the least significant digit of the number.

Peter's load limit may actually be as low as ...

  1200 kg - (1/2)(100 kg) = 1150 kg . . . . . . . 1200 is rounded to nearest 100

Peter's bar weight might be as high as ...

  60 kg + (1/2)(10 kg) = 65 kg . . . . . . . . . . . 60 is rounded to nearest 10

If Peter has maximum-weight bars and does not want to exceed the minimum his load limit might be, the number of bars he can load is ...

  (1150 kg) / (65 kg/bar) ≈ 17.7 bars

The greatest number of bars Peter can load safely is 17.

a) "how many quarters you have is a function of how many times you paid for the parking meter."

b) y = 10 - x

y: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0

Here we know that you have a total of 10 quarters, and the parking meter costs 1 quarter.

Then, each time if we define two variables:

y = how many quarters you have.

x = how many times you paid for the parking meter.

We can write:

"y is a function of x"

Or:

"how many quarters you have is a function of how many times you paid for the parking meter."

b) The rule is really simple, it would be a linear relation:

y = 10 - x

The domain (the set of possible values of x) is:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

You can't use less than 0 quarters and you can't use more than 10.

Max's and Min's: the minimum and maximum x value goes to infinity while for the y value the minimum is 0 and goes up to infinity.

Intervals: both x and y start to increase from the origin

Symmetry: the axis of symmetry is x=0 so therefore there the parabola is symmetrical

Answer:

Step-by-step explanation:

Given function:

[tex]y=3x^2[/tex]

The domain is the set of all possible input values (x-values).

The domain of the given function is unrestricted.

Therefore, the domain is (-∞, ∞).

The range is the set of all possible output values (y-values).

As x² ≥ 0, the range of the given function is [0, ∞).

A function f(x) is continuous when, for every value [tex]c[/tex] in its domain:

[tex]\text{$f(c)$ is de\:\!fined \quad and \quad $\displaystyle \lim_{x \to c} f(x) = f(c)$}[/tex]

Therefore, the function is continuous on its domain (-∞, ∞).

Stationary points occur when the gradient of a graph is zero.

Therefore, to find the x-coordinate(s) of the stationary points of a function, differentiate the function, set it to zero and solve for x.

[tex]\begin{aligned}y & = 3x^2\\\implies \dfrac{\text{d}y}{\text{d}x} & = 6x\\\\\dfrac{\text{d}y}{\text{d}x} & = 0\\\implies 6x & = 0\\x & = 0\end{aligned}[/tex]

[tex]\textsf{When} \:x = 0 \implies y=3(0)^2=0[/tex]

Therefore, the stationary point of the given function is (0, 0).

To determine if a stationary point is minimum or maximum, differentiate the function again and substitute the x-value of the stationary point:

[tex]\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & = 6x\\\implies \dfrac{\text{d}^2y}{\text{d}x^2} & = 6 \end{aligned}[/tex]

As the second derivative is positive regardless of the x-value of the stationary point, the stationary point is a minimum.

[tex]\textsf{A function is \textbf{increasing} when the \underline{gradient is positive}} \implies \dfrac{\text{d}y}{\text{d}x} > 0[/tex]

[tex]\textsf{A function is \textbf{decreasing} when the \underline{gradient is negative}} \implies \dfrac{\text{d}y}{\text{d}x} < 0[/tex]

Increasing

[tex]\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & > 0 \\ \implies 6x & > 0 \\ x & > 0\end{aligned}[/tex]

Decreasing

[tex]\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & < 0 \\ \implies 6x & < 0 \\ x & < 0\end{aligned}[/tex]

Therefore:

[tex]\textsf{A function is \underline{even} when $f(x) = f(-x)$ for all $x$.}[/tex]

[tex]\textsf{A function is \underline{odd} when $-f(x) = f(-x)$ for all $x$.}[/tex]

As x² ≥ 0 and there is symmetry about the y-axis,

[tex]\textsf{then $f(x)=f-x)$ for all $x$,}[/tex]
so the function is even.
