Answer:

2/3 pound of dough is left

Step-by-step explanation:

Amount of dough available = 6 pounds

The amount used in making sandwich rolls = 8/9 of the total amount

= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]

Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]

Hence, 2/3 pounds of dough is left

Answer:

36degrees

Step-by-step explanation:

If m<A and m<B are vertical angles, hence m<A = m<B (vertical angles are equal)

Given the following

m<A = (2x+26)°

m<B = (3x+21)°

Equating both expressions

2x + 26 = 3x + 21

2x - 3x = 21 - 26

-x = -5

x = 5

Get the measure of m<B

m<B = (3x+21)°

m<B = 3(5) + 21

m<B = 15+21

m<B = 36degrees

Hence the measure of angle B is 36degrees

Answer:

[tex]a_{n}[/tex] = 20 - 9n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 2 - 11 = - 7 - 2 = - 9

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = - 9 , then

[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Answer:

Step-by-step explanation:

(-8x+7y)(-8x+7y)+(2x-2y)(2x-2y)

=64x²-56xy-56xy+49y²+(4x²-4xy-4xy+4y²)

=64x²-112xy+49y²+4x²-8xy+4y²

=68x²-120xy+53y²

Answer:

Step-by-step explanation:

The common difference is 3.

nth term = -6+(n-1)3

-6+(n-1)3 = 162

(n-1)3 = 168

n-1 = 56

n = 57

162 is the 57th term.

S₅₇ = 57×(a_1+a_{57})/2

= 57×(-6+162)/2

= 57×156/2

= 57×78

= 57×(-6+162)/2

= 4446

Answer:

Implicit Form: 4x + y - 52 = 0

Step-by-step explanation:

8x + 2y = 104 => Move constant to the left and change the sign

8x + 2y - 104 = 0 => Divide both sides of the equation by 2

4x + y - 52 = 0

Answer:

The value of x in this equation is 3/2.

Step-by-step explanation:

First, let's take the original equation:

2 + 5x - 2x = 6x + 3x - 7

In order to solve for x, we must isolate the variable x on one side of the equation, and the rest of the numbers on the other side of the equation. So we take: 2 + 5x - 2x = 6x + 3x - 7 and use some of the properties of equality:

We start with 2 + 5x - 2x = 6x + 3x - 7 and see that we can minus 2 on both sides of the equation as highlighted below:

2 + 5x - 2x = 6x + 3x - 7

2 + 5x - 2x - 2 = 6x + 3x - 7 - 2

This simplifies the equation to 5x - 2x = 6x + 3x - 9.

Remember, we can arrange the equation like this along as we do on one side what we do on the other. Now, we have 5x - 2x = 6x + 3x - 9, and see that the rest of 6x and 3x needs to go on the left side of the equation. In order to do this, we can minus 6x from both sides of the equation as shown below:

5x - 2x = 6x + 3x - 9

5x - 2x - 6x = 6x + 3x - 9 - 6x

which then simplifies to 5x - 2x - 6x = 3x - 9. Now we can do the same thing by minus 3x from both sides of the equation.

5x - 2x - 6x = 3x - 9

5x - 2x - 6x - 3x = 3x - 9 - 3x

5x - 2x - 6x - 3x = -9

Now, we must simplify the left side of this equation by adding together the variable numbers 5x - 2x - 6x - 3x. This is shown below:

5x - 2x - 6x - 3x = -9

3x - 6x - 3x = -9

-6x = -9

Lastly, we can divide the number -9 by -6 to get the answer of what 1 x equals. This means -9/-6 = 3/2.

X is indeed equal to 3/2

Step-by-step explanation:

The total distance around the track is 332.2 meters

The complete question is in the attached image

The given parameters are:

Radius, r = 25 m

Length, l = 87.6 m

Start by calculating the circumference of the two semi-circular ends using:

[tex]C = 2\pi r[/tex]

So, we have:

C = 2* 3.14 * 25

Evaluate

C = 157

The total distance around the track is then calculated as:

Total = 2l + C

This gives

Total = 2 * 87.6 + 157

Evaluate

Total = 332.2

Hence, the total distance around the track is 332.2 meters

Answer:

209.43951 round to the nearest tenth is 209.44

Step-by-step explanation:

A cone with a base radius of 5 units and a height of 8 units has a volume of 209.44 cubed units.

If a cone has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cone (also know as a right circular cone):

V = 1/3(PI*r squared * h )

The volume of a cone can be calculated by taking one-third of the result of the radius squared, multiplied by the height, multiplied by the mathematical constant pi.

Here is a step-by-step case that illustrates how to find to volume of a cone with a radius of 2 feet and a height of 3 feet. Note that in order to save space (and because pi cannot be determine precisely) a limited number of decimal places are used, the symbol ~ denotes that this answer is an approximation.

V = 1/3(pi * r^2 * h)

= 1/3(pi * 2^2 * 3)

= 1/3(pi * 12)

= 1/3(37.7)

~ 12.6 cubic feet

Step-by-step explanation:

One is given the following information:

One is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:

[tex](Thursday)+(Friday) = Total\ distance[/tex]

Substitute,

[tex](Thursday)+(Friday) = Total\ distance[/tex]

[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]

Answer:

C. 80 square centimeters

Step-by-step explanation:

Edge 2021

The lateral surface area of the given square pyramid is 80 cm².

The lateral surface of an object is its entirety, excluding its base and top (when they exist).

Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.

Given that, a square pyramid has side lengths each measuring 8 centimeters.

The height of the pyramid is 3 centimeters.

The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]

= 2×8√[(8²/4) + 3²]

= 16√[(64/4) + 9]

= 16√[16 + 9]

= 16×5

= 80 cm²

Therefore, the lateral area of the pyramid is 80 cm².

Answer:

7pi/theta = radius

Step-by-step explanation:

So we are using the arc length, central angle(in radians), and radius.

We know arc length, which is 7pi.

We don't know theta, which does not matter.

And finally, we don;t know radius, which is what we are looking for.

To find radius, we use:

arc length/theta=radius

Lets plug in our values:

7pi/theta=radius.

So the answer to the khan acadamy question is

7pi/∅

Here are some othr things that may help:

Radian * Radius = arc length

This solves for arc length

Here is another one:

Arc length/radius= radian

This solves for radians
