The amount that Reshma spent on comic books is Rs. 165.
The amount that is left with her is Rs. 495.
How much did she spend on comic books?A fraction is a quantity that is not a whole number. A fraction consists of a numerator and a denominator. An example of a fraction is 1/4. 1 is the numerator and 4 is the denominator.
In order to determine the amount she spent on comics, multiply the fraction spent by the amount of her pocket money. Multiplication is the process used to determine the product of two or more numbers. The sign that represents multiplication is ×.
Money spent on comics = fraction of the money spent x pocket money
1/4 x 660 = Rs. 165
The amount left can be determined by subtracting the amount spent on comics by the value of her pocket money.
Amount left = pocket money - amount left
Rs 660 - Rs 165 = Rs 495

During 712months of hibernation, a black bear experienced a weight loss of 64.5 pounds.
On average, what was the bear’s weight change per month?
On average, the bear's weight change per month was 8.6 pounds.
What is the average?The average is the mean value in a data set.
We compute the average by adding the data values and dividing by the number of items in the data set.
In this scenario, the average weight loss per month offers an idea of the weight change the bear experienced during the 7¹/₂ months.
The number of months during hibernation = 7¹/₂ or 7.5 months
The total weight loss = 64.5 pounds
The average weight change per month = 8.6 pounds (64.5/7.5)
Thus, we can conclude that, on average, the bear experienced a weight loss of 8.6 pounds per month and reduced by a total of 64.5 pounds in 7¹/₂ months.

The value of x is 11.7.

What is the Angle Sum Property?According to the triangle's "angle sum property," a triangle's three inner angles can never add up to more than 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180°, regardless of whether it is acute, obtuse, or right.Given angles are:
A = (3x+8)°
B= (6x-2)°
C = 69°
Using the Angle sum property we get,
(3x+8)° + (6x-2)° + 69° = 180°
9x + 75° = 180°
9x = 180°- 75°
x = 11.7

The ratio of men to women working for a company is 4 to 7. If there is 253 employees total, how many men work at the company
Answer:
92 men
Step-by-step explanation:
First, since they give you the total employees, you need to add the ratios together to get a total.
4 + 7 = 11
Next, setup a proportion using men to total employees.
[tex]\frac{4}{11}=\frac{m}{253}[/tex]
The left side is the ratio and the right side is the actual. m will represent the total number of men employed.
Cross multiply then divide.
4 x 253 = 1012
11 x m = 11m
11m = 1012
11m/11 = 1012/11
m = 92

If CA and CE are opposite rays, CH bisects ∠ GCD, and GC bisects ∠ BGD. If m ∠ BGC = (7x - 2)° and m ∠ CGF = (8x - 8)°, then the value of m ∠ BGF exists 80°.
What is meant by angles?An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The two rays are called the sides of an angle, and the common endpoint is called the vertex.
If CA and CE are opposite rays, CH bisects ∠ GCD, and GC bisects ∠ BGD.
Given: m ∠ BGC = (7x - 2)° and m ∠ CGF = (8x - 8)°,
m ∠ BGC = m ∠ CGF
7x - 8 = 8x - 8
substracting 2 from both sides of the equation, we get
7x - 8 = 8x - 8 - 8
7x - 8 = 8x
simplifying the above equation, we get
x = 6
Therefore, the value of x = 6.
⇒ m ∠ BGC = m ∠ C G F = 40°
Therefore, the value of m ∠ BGF = 2(40)° = 80°

Answer:
0%
Step-by-step explanation:
Answer:
Step-by-step explanation:
There are 10*9 ways of selecting two biscuits (in order 1,2)
Of these 90 possible orders
2 digestives can be picked in 5*4 ways =20
2 chocolate can be picked in 2*1 ways = 2
2 ginger can be picked in 3*2 ways =6
Digestive then chocolate can be selected 5*2 ways =10
Chocolate then Digestive can be selected 2*5 ways = 10
Digestive then ginger can be selected 5*3 ways ways = 15
Ginger then digestive can be selected 3*5 ways ways = 15
Chocolate then Ginger can be selected 2*3 ways =6
Ginger then chocolate can be selected 3*2 ways = 6
I have done this the ‘long’ way to demonstrate that all 90 possible outcomes are covered. (Double check)
Probability of taking two different is then the total of the last 6 options divided by the total number of options = 2*(10+15+6)/90 = 31/45 = 68.89% (Approx.)

1) The relationship between ∠2 and ∠6 is that they are alternate angles.
2) The relationship between ∠1 and ∠3 is that they are corresponding angles.
How to find the congruent angles?Corresponding angles are defined as the angles that are formed in corresponding corners with the transversal when two parallel lines are intersected by any other line.
Alternate angles are defined as the angles that are formed by the intersection of a transversal and two parallel lines.
This alternate angle could either be interior alternate or exterior alternate.
1) Since we are told that Line 1 is parallel to Line 2, then it means that from definition of alternate angles that ∠2 and ∠6 are alternate angles.

If QR = 6x, RS = 10, and QS = 5x + 13, what is QS?
If QR = 6x, RS = 10 and QS = 5x+13, then the length of the line QS is 28 units.
The length of the line QR = 6x
The length of the line RS = 10
The length of the line QS = 5x+13
We know
The length of the line QS = The length of the line QR + The length of the line RS
Substitute the values in the equation
5x+13 = 6x + 10
Move the 6x to the left hand side of the equation and move 13 to the right hand side of the equation
5x-6x = 10-13
Subtract the terms
(5-6)x = 10-13
-1x = -3
x = 3
Then the length of the QS = 5x+13
Substitute the value of x in the equation
The length of the line QS = 5×3+13
= 15+13
= 28 units
Hence, if QR = 6x, RS = 10 and QS = 5x+13, then the length of the line QS is 28 units
