Answer:

Correct option: second one -> n / (n+1)

Step-by-step explanation:

Writting the expression, we have:

[4n / (4n-4)] * [(n-1) / (n+1)]

First we can simplify the numerator of the first part, dividing numerator and denominator by 4:

[n / (n-1)] * [(n-1) / (n+1)]

The first fraction has n-1 in the denominator and the second fraction has n-1 in the numerator, so we can simplify then in the product:

n* [1 / (n+1)] = n / (n+1)

The final expression is n / (n+1), so the correct option is the second one.

The product of the expression, 4n/(4n - 4) × (n - 1)/(n + 1), is: n/(n + 1).

Product is the multiplication of two factors in the simplest form.

Thus:

4n/(4n - 4) × (n - 1)/(n + 1)

[4(n)/4(n - 1)] × [(n - 1)/(n + 1)]

Simplify

n/(n-1) × (n-1)/(n+1)

n/(n + 1)

Therefore, the product of the expression, 4n/(4n - 4) × (n - 1)/(n + 1), is: n/(n + 1).

Answer:300

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Answer:

yes, 10

Step-by-step explanation:

Take the second term and subtract the first term

20-10 = 10

Take the third term and subtract the second term

30-20 = 10

Take the fourth term and subtract the third term

40-30 =10

Each time the difference is 10, so it is an arithmetic sequence

This is an arithmetic sequence and the common difference is 10

Answer: The answer is A 17in2

Step-by-step explanation:

In the question it states that the triangles are congruent (both the same).

  first I found the area of the top orange triangle.

the formula to find the area of a triangle is [tex]\frac{1}{2} bh[/tex] (base times Height).

so I did  [tex]\frac{1}{2} 3.23* 5.12[/tex]  which gave me 8.27.

Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.

the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

Answer:

A. 17 in2

Step-by-step explanation:

have a good day ^_^

Answer:

A

Step-by-step explanation:

In the figure attached, the complete question is shown.

We have to transform all the fractions to new fractions with the same denominator, as follows:

1/8 *4/4 = 4/32

-3/16 *2/2 = -6/32

-1/4 *8/8 = -8/32

1/32

5/32

-1/16 *2/2 = -2/32

Now we can order the list simply comparing numerators:

-8/32, -6/32, -2/32, 1/32, 4/32, 5/32

or

-1/4, -3/16, -1/16, 1/32, 1/8, 5/32

The order from least to greatest is -1/4 < -3/16 < -1/16 < 1/32 < 1/8 < 5/32 option first is correct.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

We have a measurement data as shown:

1/8, - 3/16, - 1/4, 1/32,  5/32, - 1/16

We can write the above numbers as follows:

0.125, -0.1875, -0.25, 0,03125, 0.15625, -0.0625

The order from least to greatest:

-1/4 < -3/16 < -1/16 < 1/32 < 1/8 < 5/32

Thus, the order from least to greatest is -1/4 < -3/16 < -1/16 < 1/32 < 1/8 < 5/32 option first is correct.

Answer:

The answer would be 15.

Step-by-step explanation:

The first thing that you have to do is subtract 120 on both sides

40x + 120 = 720

        -120     -120

40x = 600

Then you have to divide by 40.

40x= 600

600 ÷ 40 = 15

x = 15.

Point A

Step-by-step explanation:

Point A

The center of the circle is in the middle of the circle. Points C, T, R, and P are on the circumference of the circle, and A  is in the middle of the circle, so it is point A

Point A represents the center of the circle, the correct option is D.

A circle is a round shaped figure, all the points of a circle lie on the same plane and all the points on the circle are at equal distance from a single point called as center.

The image shows a circle.

The point which is equidistant from R,P,G, and T is A.

A is the center of the circle.

Step-by-step explanation:

Step-by-step explanation:

If the total worth of the roll is 50 cents, we know that there are 50 pennies in the roll, and therefore the roll has a height of 50 * 1.52 = 76 mm. The radius of a penny is half its diameter, or 19.05 / 2 = 9.525.

We can find its volume with the formula (πr²) * h, where r and h are the radius and height respectively, and we can approximate 3.14 for π. Plugging these in, we have (3.14 * (9.525)²) * 76 ≈ 2160.8 mm³. Hope this helps!

Answer:

  21,661.7 mm³

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr²h

Here, we're given the diameter as 19.05 mm, so the radius is ...

  r = 19.05 mm / 2 = 9.525 mm

The thickness of one penny is 1.52 mm, but there are 50 of them in the roll. So the total height of this cylinder is ...

  h = (1.52 mm)(50) = 76 mm

__

Using these numbers for radius and height in the volume formula, we find the volume of the roll of pennies to be ...

  V = π(9.525 mm)²(76 mm) = 21,661.7 mm³

The approximate volume of the roll of pennies is 21,661.7 mm³.

Answer:

x=12

Step-by-step explanation:

90 = x + 42 + 3x

48 = x + 3x

48 = 4x

12 = x

Answer:

x = 12

Step-by-step explanation:

Since we are given a right angle, we can say that:

sum of all angles = 90 degrees

x + 42 + 3x = 90

4x = 48

x = 12

So, x is equal to 12 degrees!
