Answer the question in the photo
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:
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:
[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!

35 is what percent of 25
Answer:
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.

A 1/2 cup serving of ice cream contains 140 calories. How many calories would be in a 3/4 cup serving?
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.
Number of calories in 3/4 cupYou 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.

Point A Represents (3,-5π/3).
What is a polar coordinate?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).

A 26-by-27-inch sheet of paper is to be used for a poster, with the shorter side at the bottom. Find the width of the margins if the printed area is to be 360 in2.
Answer:
Step-by-step explanation:
Let the width of the margins as x.
So, we subtract 'x' width on each side of the paper.
So, length = 26-x-x= 26-2 x
Width = 27-x-x=27-2 x
Now, it is given printed area is 360
We can set up equation using length x width = Area
(26-2 x)(27-2 x) = 360
Multiply the left side using FOIL method,
702 -52 x-54 x+4 x^2 =360
Combine like terms
702-106x+4x^2=360
Subtract both sides 360
4x^2-106x+342 =0
Let's divide both sides by 2 to simplify
2x^2 -53x+171=0
Let's use quadratic formula to solve.

Golf balls come in a variety of packages. A particular brand of golf balls come in packages of 12 or in packages of 18. The 12-pack costs $4.47 and the 18-pack costs $14.46. Which is the better deal and what is the unit price of the better deal?
Answer:
The better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.
Step-by-step explanation:
To find which is the better deal, you have to determine which one offers a lower unit price by dividing the price of each package by the number of balls in the pack:
$4.47/12=$0.37
$14.46/18=$0.80
According to this, the answer is that the better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.
A circle has its centre at the origin and has equation
x + y = 81
What is the size of the radius?
Answer:
radius = 9
Step-by-step explanation:
The equation of the circle centred at the origin is
x² + y² = r² ( where r is the radius )
Given
x² + y² = 81, then
r² = 81 ( take the square root of both sides )
r = [tex]\sqrt{81}[/tex] = 9
