Factoring expressions: 17x-34xy

Answers

17x(1-2y)

17x-34xy

because both expressions have a x, it would be easier to factor out the x first. but because 17 is a factor of 34 you can simply divide 34 by 17 and get 2. so you put it together to this,

17x(1-2y)

Because, 17x times 1 is 17x but 17x times -2y would be -32xy.

Answer:

17x(1-2y)

Step-by-step explanation:

1) so "x" is common in this expression so lets take that out first:

x(17-34y)

2) but 17 is also common since 17*2=34 so lets take "17" out:

17x(1-2y)

Pierce is making a rectangular frame for a photo collage that has a perimeter of 72.2 72.2 inches. The length of the frame is 20.3 20.3 inches. Write an equation to find the width of the frame, x

Answers

Answer:

[tex] P = 2x+2y[/tex]   (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

[tex] P-2y = 2x[/tex]

[tex] \frac{P-2y}{2} =x[/tex]

And replacing we got:

[tex] x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in[/tex]

And the width for this case would be 15.8 in

Step-by-step explanation:

For this case we know that the photo is rectangular. Let's define:

x = the width,  y= the length

And we know that the perimeter is given by:

[tex] P = 2x+2y[/tex]   (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

[tex] P-2y = 2x[/tex]

A spinner with seven equal sized sections was used to play a game It was used 250 times in the first game Of those 250 the arrow landed on section 7 a total of 35 times The same spinner was used 150 times in the second game How many times did the spinner most likely land on section 7 in the second game A. 14 B. 21 C. 30 D. 35

Answers

Answer: 21

Step-by-step explanation:

From the question, a spinner with seven equal sized sections was used in playing a game. The spinner was used 250 times in the first game and the arrow landed on section 7 a total of 35 times. This can be expressed as:

= 35/250

= 0.14

The same spinner was also used 150 times in the second game. The number of times the spinner will most likely land on section 7 in the second game will be:

= 0.14 × 150

= 21

The spinner most likely land on section 7 in the second game for 21 times.

can net worth be negative?

Answers

Answer:

our net worth can tell you many things. If the figure is negative, it means you owe more than you own. If the number is positive, you own more than you owe. ... Negative net worth does not necessarily indicate that you are financially irresponsible; it just means that – right now – you have more liabilities than assets

Step-by-step explanation:

hope it help

Yes, of course.  A good fraction of the people on earth owe more than they own, so have negative net worth.  

In the USA about 14% of the households have negative net worth.  I would have guessed that credit card debt was the culprit, but it's mostly student loans that drag folks into this category.

What is the next term in this sequence: 76, 80, 88, 95, 100, 101


I’m stuck

Answers

Answer:

112

Step-by-step explanation:

Given the sequence 76, 80, 88, 95, 100, 101... Before we can get the next term of the sequence, we must first understand the pattern. We are not going to be considering all the terms of the sequence. In the sequence, only the following values forms a pattern as shown;

76, 88, 100... This are the  first, third and fifth term of the sequence. The next term will be the 7th term of the sequence and the 4th term of the extracted sequence which is what we are looking for.

Note that the extracted forms an arithmetic sequence with 76 as its first term and 12 as its common diffidence (i.e 88-76 = 100-88).

Using the nth term of an AP to find the next term of the sequence we have;

[tex]Tn = a + (n-1)d[/tex]

a is the first term = 76

d is the common difference = 12

n is the number of terms = 4 (since we are looking for the 4th term of the extracted sequence)

[tex]T4 = 76+(4-1)*12\\T4 = 76 + (3*12)\\T4 = 76 + 36\\T4 = 112[/tex]

The next term in the sequence is 112

Answers

Question:

Anderson’s Nursery was choosing between two different greenhouses.

2 greenhouses have a rectangular prism base with a length of 12 meters, width of 12 meters, and height of 10 meters.

Greenhouse 1 has a square pyramid top with a base of 12 meters by 12 meters and height of 8 meters.

Greenhouse 2 has a triangular prism top. The triangular sides have a base of 12 meters and height of 8 meters. The prism has a height of 12 meters.

Which statements are true about the greenhouses? Select two options.

A) The space inside greenhouse 1 can be found using the equation V = 12 (12) (10) + one-half (12) (12) (8).

B) The space inside greenhouse 1 can be found using the equation V = 12 (12) (10) + one-third (12) (12) (8).

C) The space inside greenhouse 2 can be found using the equation V = 12 (12) (10) + one-half (12) (12) (8).

D) The space inside greenhouse 2 can be found using the equation V = 12 (12) (10) + one-third (12) (12) (8).

E) The space inside greenhouse 1 is 192 meters cubed greater than the space inside greenhouse 2.

Answer:

Options B & C are correct.

Step-by-step explanation:

Given that both greenhouses have a rectangular prism base with a length of 12 meters, width of 12 meters, and height of 10 meters.

L = 12 m

w = 12 m

h = 10 m

To find the volume of this rectangular prism, let's use the formula:

V = w*h*l

V = 12 * 12 * 10

V = 1440 m³

Then, greenhouse 1 has a square pyramid top with a base of 12 meters by 12 meters and height of 8 meters.

b = 12 x 12

h = 8

The volume of a square pyramid formula is:

V = ⅓*a²h

V = ⅓*12²*8

V = 384 m³

To find the total volume of greenhouse 1, let's add the volume of the rectangular prism and the square pyramid.

V = 12*12*10 + ⅓*12²*8

V = 1440 + 384 = 1824m³

Therefore, the space inside greenhouse 1 is 1824m³

Similarly, greenhouse 2 has a triangular prism top. The triangular sides have a base of 12 meters and height of 8 meters. The prism has a height of 12 meters.

b = 12 m

h = 8 m

height of prism = 12 m

To find the volume of a triangular prism, we have:

½*(bh) * h

V = ½(12*8)*12

V = 576 m³

To find the total volume of greenhouse 2, let's add the volume of the rectangular prism and the triangular prism.

V = (12 * 12 * 10) + (½(12*8)*12)

V = 1440 + 576

V = 2016 m³

Therefore, the space inside greenhouse 2 is 2016m³

From the calculations above the correct options would be:

(B) The space inside greenhouse 1 can be found using the equation V = 12 (12) (10) + one-third (12) (12) (8).

(C) The space inside greenhouse 2 can be found using the equation V = 12 (12) (10) + one-half (12) (12) (8).

Options A, D and E are wrong.

Option E is wrong because the space inside greenhouse 1 is (1824-2016 = -192) 192 meters cubed lesser than the space inside greenhouse 2.

Answer:

THE ANSWERS ARE.... B AND C

B: The space inside greenhouse 1 can be found using the equation V = 12 (12) (10) + one-third (12) (12) (8).

C: The space inside greenhouse 2 can be found using the equation V = 12 (12) (10) + one-half (12) (12) (8).

A basketball team wants to paint half of a free-throw circle grey. If the radius of the free-throw circle is 5.4 feet, what is the area that will be painted grey? Use 3.14 for , and round to the nearest square foot.

Answers

Answer:

The area which would be painted grey will be "47.7812 ft²".

Step-by-step explanation:

The given values are:

Radius of circle, r = 5.4 feet

Value of pi, π = 3.14

As we know,

Area of Semicircle = [tex]\frac{\pi r^2}{2}[/tex]

On putting the values in the above formula, we get

                               = [tex]\frac{3.14\times (5.4)^{2}}{2}[/tex]

                               = [tex]\frac{3.14\times 29.26}{2}[/tex]

                               = [tex]\frac{91.5624}{2}[/tex]

                               = [tex]45.7812 \ ft^2[/tex]

The area of one of the smaller circles is 8/ in². Find the area of the shaded region.


A. pi in.²

B. 4 pi in.²

C. 8 pi in.²

D. 16 pi in.²

The answer is D btw i just submitted my quiz

Answers

Answer:

Area of shaded region = 16π in² (D)

Step-by-step explanation:

The question is incomplete without the diagram if the circles. Find attached the diagram used in solving the question.

Area of the smaller circle = 8π in²

Area of a circle = πr²

πr² = 8π

r² =8

r = √8 = 2√2

From the diagram, there are two smaller circles in a bigger circle.

The radius of the bigger circle (R) is 2times the radius of the smaller circle (r)

R = 2r

Area of bigger circle = πR²

= π×(2r)² =   π×(2×2√2)²

= π×(4√2)² = π×16×(√2)²

Area of bigger circle = π×16×2

Area of bigger circle = 32π in²

Since there are two smaller circles in a bigger circle

Area of shaded region = Area of bigger circle -2(area of smaller circles)

Area of shaded region = 32π in² - 2(8π in²)

Area of shaded region = 32π in² - 16π in²

Area of shaded region = 16π in²
