A cake was cut into 12 equal pieces. Someone ate part of the cake so that 3/4 of the cake remains. How many 1/12 pieces are left?

Answer:

Angle 6

Step-by-step explanation:

Angles on opposite ends are congruent if they are formed by the same two lines or in other words, if the two angles are vertical angles.

Step-by-step explanation:

1.2+2.3+3.4+⋯+n(n+1)=∑k=1nk(k+1)

=∑k=1n(k2+k)

=∑k=1n(k2)+∑k=1n(k)

=n(n+1)(2n+1)6+n(n+1)2

=n(n+1)6(2n+1+3)

=n(n+1)6(2n+4)

=n(n+1)6[2(n+2)]

=n(n+1)(n+2)3

Answer:

You have to think in three dimensions to answer this properly. The relative size of the pieces was never specified, so let’s start with the first three cuts:

Cut 1: No specified angle—-but it’s vertical and along a diameter (assuming a circular pie): 2 pieces.

Cut 2: Perpendicular to Cut 1; also vertical: 4 pieces.

Cut 3: Horizontal across the midline of the pie: 8 pieces.

Cuts 4 and 5: Diagonally—from either end of cut 1 on top to the opposite sides on the bottom (they intersect at the center): 16 pieces.

Cuts 6 and 7: Diagonally from the ends of cut 2 (similar to cuts 4 and 5): 32 pieces.

Cut 8: The exact angle is unimportant—it’s difficult if not impossible to cut more than half of the pieces. So of 32, 16 are split, leaving a grand total of 48 pieces.

There could very well be a way to make more than 48 pieces, but I would have written that one if I’d thought of it.

Step-by-step explanation:

With eight straight cuts, approximately 18 pieces of pie can be made.

An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -

2x + 3y + 5

2z + y

x + 3y

Given is that a pie can be cut into seven pieces with three straight cuts.

With three straight cuts, the number of pieces would be seven.

With 1 straight cut, the number of pieces would be 7/3.

With 8 straight cut, the number of pieces would be 7/3 x 8 = 56/3 = 18.6

Therefore, with eight straight cuts, approximately 18 pieces of pie can be made.

Answer: 1750J

Step-by-step explanation:

The work done that will be used to loft the barbell and the hanging chain will be:

W1 = (1300 + (1/2 × 600))

= 1300 + 300

= 1600J

The work done that'll be used in lifting the upper part of the chain will be:

W2 = (1/2 × 600) × (1/2 × 1).

= 300 × 0.5

= 150J

Total work down will be:

=W1 + W2

= 1600J + 150J

= 1750J

Answer:

The answer is y < 2x -3

Step-by-step explanation:

You can read this as all values on the graph will be the value of x times 2 minus 3..

For example, if we wanted to know what the value of y would be if x =2, we would plug in 2 and get 2(2) - 3 or just 1. We can see at the graph that when x = 2 y does equal 1. **In this situation we are pretending that the < symbol is the equal symbol..

To actually find the answer you can graph each equation until you find it or do it this way:

1) Find the slope and determine if it it works for the given graph.

We can see that the slope of the given graph is positive and if we look closer we can see that the slope is 2 over  and that we have a y-intercept of (0,-3).

2) We know that it is Option 2 instead of the first option because o the < sign. If it was option 1, then the shaded part of the graph would be on the other side of the line.

The inequality has the graph shown in the question. is to be considered as the  y < 2x -3.

Since

First determine the slope

So we can see that the slope of the given graph should be positive and then the slope should be 2 over and there is y-intercept of (0,-3).

So based on this, we can say that The inequality has the graph shown in the question. is to be considered as the  y < 2x -3.

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define expression

4(-8x + 5) - (-33x - 26)

Step 2: Simplify

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

Explanation:

Expand out the expression using the FOIL rule

(x+7)(x-7)

x^2 - 7x + 7x - 49

1x^2 + 0x - 49

We see that a = 1, b = 0, c = -49

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

Another way to expand is to do the following

(x+7)(x-7)

y(x-7) .... let y = x+7

xy - 7y .... distribute

x( y ) - 7( y )

x( x+7 ) - 7( x + 7 ) ... replace y with x+7

x^2 + 7x - 7x - 49 .... distribute

1x^2 + 0x - 49

We get the same result.

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

Lastly, a shortcut can be used as yet another method to expand.

The shortcut is the difference of squares rule

(a + b)(a - b) = a^2 - b^2

In this case, a = x and b = 7, so,

(a + b)(a - b) = a^2 - b^2

(x + 7)(x - 7) = x^2 - 7^2

(x + 7)(x - 7) = x^2 - 49

(x + 7)(x - 7) = 1x^2 + 0x - 49

Answer:

[tex]y=7[/tex]

Step-by-step explanation:

First, let's use the two given points to find the slope. Remember the slope equation:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{7-7}{0-4}[/tex]

[tex]m=\frac{0}{-4}[/tex]

[tex]m=0[/tex]

If we're following slope-intercept form, what we have so far is

[tex]y=0x+b[/tex]

Substitute one of the given points for the [tex]x[/tex] and [tex]y[/tex] values in order to find [tex]b[/tex]:

[tex]7=0(4)+b[/tex]

[tex]7=b[/tex]

Now, if we put that back into our slope-intercept equation we get

[tex]y=0x+7[/tex]

or,

[tex]y=7[/tex]

Right off the bat, we can see how we ended up with this equation because both points have the same y-values. This indicates a horizontal line.

Answer:

B. [tex]-2\frac{1}{2}[/tex]

Step-by-step explanation:

First you need to get the least common denominator of the left

-7 3/4 and 1/2 the LCD is 4 so...

(1/1) 3/4 = 3/4 (This doesn't have to change since the denominator is already 4)

(2/2) 1/2 = 2/4

Let's make -7 3/4 into an improper fraction = -31/4

Let's make -2 1/4 into an improper fraction = -9/4

Plug back in

-31/4 - 2w + 2/4 [tex]\leq[/tex] -9/4 (collect like terms)

-29/4 - 2w [tex]\leq[/tex] -9/4 (add 29/4 on both sides)

-2w = 5 (divide by -2)

w = -5/2 or -2 1/2

Step-by-step explanation:

Answer:

cost of each kettle:

gain/loss from each transaction:

total loss = 65

loss % = 4%

Step-by-step explanation:

both kettles cost 1625

K₁ + K₂ = 1625

selling price of K₁ = [(100 + 20) / 100] x K₁ = 1.2K₁

selling price of K₂ = [(100 - 80) / 100] x K₂ = 0.8K₂

1.2K₁ = 0.8K₂

K₁ = 1625 - K₂

K₁ = 0.8K₂ / 1.2

1625 - K₂ = ²/₃K₂

1625 = ²/₃K₂ + K₂ = ⁵/₃K₂

K₂ = 1625 x ³/₅ = 975

K₁ = 1625 - K₂ = 1625 - 975 = 650

selling price = 1.2K₁ = 1.2 x 650 = 780

selling price K₂ = 0.8K₂ = 0.8 x 975 = 780

gain from selling K₁ = 780 - 650 = 130

loss from selling K₂ = 780 - 975 = 195

total loss = 195 - 130 = 65

loss % = 65 / 1625 = 0.04 = 4%

Answer:

D. [tex] = \frac{b}{a} [/tex]

Step-by-step explanation:

Given:

[tex] \frac{b^{-2}}{ab^{-3}} [/tex]

Required:

Assuming a ≠ 0, b ≠ 0, find the expression equivalent to the given expression.

SOLUTION:

[tex] \frac{b^{-2}}{ab^{-3}} [/tex]

Recall the exponent rule =>  [tex] \frac{x^{a}}{x^{b}} = x^{a - b} [/tex]

Applying the exponent rule, we would have:

[tex] \frac{b^{-2 -(-3)}}{a} [/tex]

[tex] = \frac{b^{-2 + 3}}{a} [/tex]

[tex] = \frac{b^{1}}{a} [/tex]

[tex] = \frac{b}{a} [/tex]

Thus, the equivalent expression of [tex] \frac{b^{-2}}{ab^{-3}} [/tex] = [tex] \frac{b}{a} [/tex]

C. Number cube

Let even number = rock

Let odd number = pop

Roll cube three times. Repeat

If she wants to estimate the probability that the next three songs are all rock songs, what she can do is to assign specific type of digits to each type of song.

The reason why I used even and odd numbers is because we are told that there are equal number of POP and rocks songs and from 0 to 9, we have equal number of even and odd numbers.
