Help with this question please

Answer:

B and C

Step-by-step explanation:

Both B and C

B)

2/5 = 0.4 (which terminate as decimals)

Similarly

C)

-1/4 = -0.25 (also terminates)

But A and D do not terminate

As for A) 1/3= 0.33333333..........

and for D) 7/9= 0.777777777......

In both cases the decimals are a never ending sequence or in other words does not terminate at all. They are irrational numbers.

Hope you understand. Thank you.

Answer:

96 students attend chess club after school on Wednesday's.

Step-by-step explanation:

To solve this problem, simply multiply 800 x 0.12.

    800 x 0.12 = 96

I hope this was helpful to you! If it was, please consider rating, pressing thanks, and marking my answer Brainliest. It would help a lot. Have a great day!

Answer:

[tex]\huge\boxed{\text{96 students}}[/tex]

Step-by-step explanation:

In order to find how many students stay back for Chess Club, we want to find 12% of 800.

To do this, we can set up a percentage proportion.

[tex]\frac{12}{100} = \frac{x}{800}[/tex]

We can now solve for x by cross multiplying.

[tex]800 \cdot 12 = 9600\\9600 \div 100 = 96[/tex]

So, 96 students attend Chess Club on Wednesdays.

Hope this helped!

Answer:

This would be 26 x + 189

Answer:

C.

Step-by-step explanation:

A has 8 lines of symmetry, because they're all the same.

B has 4 lines of symmtery because those are all the same

C has only 2 because the vertical lines are symmetrical to each other, but not to the horizontal lines

D has 10 symmetrical lines because they're all the same

Answer:

Okay so on the first one it would be congruent because they have  congruent sides or angles. (Hint: Look at the tick marks on both triangles and see if they match up, if they do then they are congruent.) I hope this helps you have a great day! <3

Answer:

A edge 2021

Step-by-step explanation:

Point A Represents (3,-5π/3).

The distance from a point to the origin (r) and the angle this line makes with a fixed line (Θ) are the two coordinates that specify where a point is located in a plane.

The radius of circle is 3 units.

The angle in the polar coordinate measured clockwise is considered negative and measured anticlockwise as positive.

In order to get the position of the angle from the x-axis the angle should be added by 2π as

Θ = 2π-5π/3

Θ = π/3

The angle is calculated clockwise.

From the diagram point, A represents the angle  π/3.

Thus, the Point A Represents (3,-5π/3).

Answer:

Step-by-step explanation:

the bat is 12. the pumpkin is 5. and the weird looking thing is 14

14 plus 14 plus 12 is 40

12 minus 5 is 7

5 plus 14 is 19

14 minus 5 plus 12 is 21

Answer:

  21

Step-by-step explanation:

Green bat:   x

Purple bat:   y

  Pumpkin:   z

Given:

  2x + y = 40

  y - z = 7                ===>      y = 7 + z

  z + x = 19             ===>       z = 19 - x

Substitution to find green bat x:

  2x + y = 40

  2x + (7 + z) = 40

  2x + 7 + z = 40

  2x + 7 + (19 - x) = 40

  2x + 7 + 19 - x = 40

  x + 26 = 40

  green bat:  x = 14

Substitution to find pumpkin z:

  z + x = 19

  z + (14) = 19

  z + 14 = 19

  pumpkin:  z = 5

Substitution to find purple bat y:

  y - z = 7

  y - (5) = 7

  y - 5 = 7

  purple bat:  y = 12

Solve for x - z + y:

  14 - 5 + 12 = 21

Answer: - 4

because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees

=> the temperature at noon was -12 + 16 = 4 (degrees)

At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:

4 - 8 = -4 (degrees)

Step-by-step explanation: Convert fraction (ratio) 35 / 25 Answer: 140%

The number 35 is 140% of the given number 25.

A fraction or proportion expressed as a percentage of 100 is called a percentage. "%" is used to represent it. Frequently, percentages are employed to indicate relative values, compare amounts, and represent components of a total.

To find out what percent 35 is of 25, we can use the following formula:

Percent = (Part / Whole) * 100

Identify the part and the whole. In this case, 35 is the part and 25 is the whole.

Substitute the values into the formula:

Percent = (35 / 25) x 100

Simplify the expression inside the parentheses:

Percent = 1.4 x 100

Multiply the simplified expression by 100:

Percent = 140

Therefore, 35 is 140% of 25.

Answer:

There would be 210 calories in a 3/4 cup serving.

Step-by-step explanation:

1/2 of 140 = 70

70 = 1/4

70 x 3 = 210 = 3/4

I hope this helped you! If it did, please consider pressing thanks, rating my answer, and marking as Brainliest. It would be a big help! Have a great day! :)

Based on the number of calories in 1/2 cups, the number of calories in 3/4 cups is 210 calories.

You can use direct proportion to solve for this by assuming that the calories in 3/4 cups is x:

1 / 2          :         140 calories

3 / 4          :        x

Cross multiplying would give:

1/2x = 105

x = 105 ÷ 1/2

x = 210 calories

In conclusion, there would be 210 calories in 3/4 cups.
