The video game was originally $38. This weekend it is 13% off. After applying this discount, the game will cost $33.06.
Explanation:The subject of your question lies in the realm of Mathematics, specifically focusing on a practical application: calculating a discount. In this case, the video game was originally $38 and this weekend, there is a discount of 13%. Since the discount is a percentage off of the original price, you need to multiply $38 by 13% (or 0.13, when presented as a decimal).This operation gives us: $38 * 0.13 = $4.94.This means the discount is $4.94. To find out how much the video game costs after the discount has been applied, you need to subtract this amount from the original price of the game. Therefore, the price of the game this weekend will be: $38 - $4.94 = $33.06.

what is the height of a building in meters if it takes a rock 3.8 seconds to drop from its roof
Final answer:
Using the formula for the distance fallen under gravity, the height of the building is found to be approximately 70.856 meters, given a drop time of 3.8 seconds.
Explanation:
The question asks, "What is the height of a building in meters if it takes a rock 3.8 seconds to drop from its roof?" To solve this, we'll use the physics formula for the distance (height) fallen by an object under gravity, which is given by d = ½ gt², where d is the distance in meters, g is the acceleration due to gravity (approximately 9.8 m/s²), and t is the time in seconds.
Substituting the given values into the equation, we have:
d = ½ × 9.8 m/s² × (3.8 s)²
= ½ × 9.8 × 14.44
= 70.856 meters
Therefore, the height of the building is approximately 70.856 meters.

Georgie needs to paint the wall with a fixing mixture.
She mixes glue and water in the ratio 3:1 to make the mixture.
Georgie needs 5 litres of the mixture.
She has 3.5 litres of glue. Does Georgie have enough glue to make 5 litres of the mixture?
Answer:
You will need approximately 1.17 L of water with 3.5 L of glue. This is a total of 4.67 L, which is NOT enough.
Step-by-step explanation:
Georgie has 3.75 litres of glue which is enough to make 5 litres of the mixture.
What is the ratio?A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.
Now it is given that,
Ratio of glue and water = 3 : 1
Amount of mixture = 5 litres
Georgie has glue = 3.5 litres
Now let x be the number,
So, Amount of glue in the mixture = 3x
and, amount of water in the mixture = x
⇒ Amount of mixture = 3x + x
⇒ 3x + x = 5
⇒ 4x = 5
⇒ x = 5/4
⇒ x = 1.25
Thus, Amount of glue in the mixture = 3*1.25 litres
⇒ Amount of glue in the mixture = 3.75 litres
So, Amount of glue in the mixture is greater than amount of glue Georgie has.
Thus, Georgie has 3.75 litres of glue which is enough to make 5 litres of the mixture.

each side of rectangular polygon is 2.5cm in length .the perimeter of the polygon is 12.5cm.how many sides does the polygon have
There are 5 sides (a pentagon). The perimeter is the length of one side times the number of sides.
Regular polygon has same length for all sides.The polygon has 5 sides. The specific type of polygon with 5 sides is called a pentagon.
The perimeter of a polygon is the total length of all its sides. In a regular polygon, all sides are equal in length. So, if each side of the polygon is 2.5 cm and the perimeter is 12.5 cm, we can find the number of sides by dividing the perimeter by the side length:
Number of sides = Perimeter / Side length
Number of sides = 12.5 cm / 2.5 cm
Number of sides = 5

How much will Maria spend on flour to make her cookies? A. $1.55 B. $2.25 C. $3.80 D. $5.35
By converting mixed numbers to decimals and multiplying the total number of cups of flour by the cost per cup, we find out Maria will spend $3.80 on flour, which is option C.
To find out how much Maria will spend on flour to make her cookies, we need to calculate the total cost of white and whole wheat flour. Maria needs 3 1/10 cups of white flour and 4 1/2 cups of whole wheat flour. First, we convert the mixed numbers to decimal form: 3 1/10 cups is 3.1 cups, and 4 1/2 cups is 4.5 cups. Then we add them together to find the total number of cups Maria will use:
3.1 cups + 4.5 cups = 7.6 cups
Next, since flour costs $0.50 per cup, we multiply the total number of cups by the cost per cup:
7.6 cups × $0.50 per cup = $3.80
Therefore, Maria will spend a total of $3.80 on flour for her cookie recipe, making the correct answer C. $3.80.

The area of the circle with circumference [tex]\( 12\pi \)[/tex] is [tex]\( \boxed{36\pi} \)[/tex] square units.
To find the area of a circle when given its circumference, we start by using the formula relating circumference ([tex]\( C \)[/tex]) and radius ([tex]\( r \)[/tex]):
[tex]\[ C = 2\pi r \][/tex]
Given that the circumference [tex]\( C \)[/tex] is [tex]\( 12\pi \)[/tex], we set up the equation:
[tex]\[ 12\pi = 2\pi r \][/tex]
Next, solve for [tex]\( r \)[/tex] by dividing both sides by [tex]\( 2\pi \)[/tex]:
[tex]\[ r = \frac{12\pi}{2\pi} \][/tex]
[tex]\[ r = 6 \][/tex]
Now that we have found the radius [tex]\( r = 6 \)[/tex], we can find the area ([tex]\( A \)[/tex]) of the circle using the formula for the area of a circle:
[tex]\[ A = \pi r^2 \][/tex]
Substitute [tex]\( r = 6 \)[/tex]:
[tex]\[ A = \pi \cdot (6)^2 \][/tex]
[tex]\[ A = \pi \cdot 36 \][/tex]
[tex]\[ A = 36\pi \][/tex]
Therefore, the area of the circle with a circumference of [tex]\( 12\pi \)[/tex] is [tex]\( \boxed{36\pi} \)[/tex].

Find the value of x.
Answer: The required value of x is 64.
Step-by-step explanation: We are given to find the value of x from the figure.
From the figure, we see a right-angled triangle in which an acute angle has measurement x°.
And, for the angle with measurement x°, the base has a length of 3.0 units and hypotenuse has a length of 6.8 units.
Therefore, the cosine of that angle will be
[tex]\cos x^\circ=\dfrac{base}{hypotenuse}\\\\\\\Rightarrow \cos x^\circ=\dfrac{3.0}{6.8}\\\\\\\Rightarrow \cos x^\circ=0.4411\\\\\Rightarrow x^\circ=\cos^{-1}(0.4411)\\\\\Rightarrow x^\circ=63.83^\circ\\\\\Rightarrow x=63.83.[/tex]
So, to the nearest whole number, we get
x = 64.
Thus, the required value of x is 64.
