What comes next in this pattern? (add 4/6)

1/6, 5/6, 1 3/6, ...

A.1 5/6
B.2 2/6
C.2 4/6
D.2 1/6

Answers

Answer:

D. 2 1/6

Step-by-step explanation:

To visualize the problem easier, start by converting all the fractions to improper fractions, this will allow you to just add the denominators and simplify the question:

1/6, 5/6, 1 3/6 —> 1/6, 5/6, 9/6

Now that the sequence is rewritten, you can simply add 4 to the numerator, which equals 13/6.

Rewrite this again by finding how many times 6 goes into 13, and use the remainder as the numerator of the new fraction, which will end up as 2 1/6.

The answer to this question is D.

Bro i dont know if i am right but here we go

The answer most likely is 80

Step-by-step explanation:

By useing a bit of geometry instead of useing two angles to find your last angle.

So first notice how there are two of the same sides (14)but one differnt side(18) okay nice

With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.

So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80

I hope you understand and im sorry if this is wrong.

Answer the two questions below
3. Suppose that you are going to select a random sample of students from your school, measure the heights of the students in your sample, and then find the mean height for your sample. There are many different sets of students who could end up forming your sample. Will the sample mean be the same for all possible samples? If so, explain why. If not, what is the phrase used for the fact the sample means will vary according to the sample selected?

4. Return to the context of the previous item. The sample mean will vary according to what sample you happen to select. If you want to reduce this variation, would you choose to select a sample of size 5 or a sample of size 25?

Answers

Answer:

3: No

4: 25

Step-by-step explanation:

3: It won't because not everyone is the same height and there will be variation in the mean height.

4: A larger sample size will give a more accurate representation of the population, where as a sample size of 5 is much more likely to have a higher percentage of outliers, and each outlier matters much more in finding the mean. In a sample size of 25, each outlier matters much less.

A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 212cm. The prism is filled with cubes that have edge lengths of 12 cm. How many cubes are needed to fill the rectangular prism? Enter your answer in the box.

Answers

Answer:

first solve the volume of the rectangular prism

V = l x w x h

where l is the length

w is the width

h is the height

V = 7 x 4 x 2.5

v = 70 cu cm

then solve the volume of the box

v = e^3

v = 0.5^3

v = 0.125

number of cubes = 70 / 0.125

number of cubes = 560 cubes

A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?

Answers

Answer:

192

Step-by-step explanation:

The area of the cereal box = 8 x 3 x 10 = 240

Therefore, if 100% of the box is filled with

cereal, the amount of cereal in the box

will be 240.

now, 80% is x

80/100 = x/240

cross multiplying,

100x = 80×240

100x = 19 200

dividing both sides by 100

x = 192

Answer:

192

Step-by-step explanation:

Simplifying

41n(7x) = 8

Remove parenthesis around (7x)

41n * 7x = 8

Reorder the terms for easier multiplication:

41 * 7n * x = 8

Multiply 41 * 7

287n * x = 8

Multiply n * x

287nx = 8

Solving

287nx = 8

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Divide each side by '287x'.

n = 0.02787456446x-1

Simplifying

n = 0.02787456446x-1

A Ferris wheel rotates three times when it travels 235.5 feet. Find the diameter of the Ferris wheel. Use 3.14 for pi

Answers

Answer:

try 3.14 x 3.14 / 235.5 and that should be your awnser.

Step-by-step explanation:

the equation for diameter is d=2r which is pi times pi divided my the number. if i remeber correctly. lmk if im wrong

Answer: The diameter is 10cm

Step-by-step explanation:

First, we divide 78.5/3.14 which = 25

Now, we find the square root of 25 to find the radius, which is 5.

The radius is 5cm, which means that the diameter is 10cm.

The diameter of the Ferris wheel is 10cm.

If we recalculate the area again with the diameter given, we can see that:

AREA = 3.14r2

AREA = 3.14 x 5 squared ( radius is half diameter )

AREA = 3.14 x 25 = 78.5

Answers

In the graph, the highest or lowest point of a parabola is the vertex. The vertex of the graph of y=x2 is (0,0). If a>0 in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola. so the vertex and the equations will lead to finding a parabola.

Answer:

1) r = 20.2/2

= 10.1 mm

circumference = ( (1/2) (2) (π) (10.2) )

= 32.04 mm

perimeter = (3.1 + 3.1 + 20.2 + ( (1/2) (2) (π) (10.2) )

= 58.13 mm

2) circumference = (1/4) (2) (π) (307.34)

perimeter = (11.5 + 11.5 + (2 * 10.1) + ( (1/4) (2) (π) (307.34) )

= 525.97 mm

3) circumference = (3/4) (2) (π) (2.5)

= 11.78 cm

4) circumference = (3/4) (2) (π) (2.5)

= 23.56 cm

5) circumference = (1/2) (2) (π) (32)

= 100.53 cm

6) r = 6/2 = 3 cm

circumference = (1/2) (2) (π) (3)

= 9.42 cm

perimeter = (2 + 2 + 6 + ( (1/2) (2) (π) (3) )

= 19.42 cm
