A video game was $38. This weekend the game will be marked 13 percent off. How much is the game this weekend?
Answers
Cost of the game after discount = $38 - $4.94 = $33.06
Answer: $33.06
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.

Kelly has 236 feet of fence to use to enclose a rectangular space for her dog. She wants the width to be 23 feet. Draw a rectangle that could be the space for Kelly's dog. Label the length and the width.
Answers
length=?
p= 2l+2w
236=2l+2(23)
236=2l+46
190=2l
l= 95ft
Final answer:
To create the space for Kelly's dog, a rectangle with a length of 118 feet and a width of 23 feet should be drawn.
Explanation:
To draw a rectangle that could be the space for Kelly's dog, we need to consider the given information. Kelly has 236 feet of fence to use, and she wants the width to be 23 feet.
Since the opposite sides of a rectangle are equal in length, we can divide the total amount of fence by 2 to determine the length of each side. 236 feet / 2 = 118 feet.
So, the rectangle that could be the space for Kelly's dog would have a length of 118 feet and a width of 23 feet.

A quality control officer randomly checking weights of pumpkin seed bags being filled by an automatic filling machine. Each bag is advertised as weighing 400 grams. A bag must weigh within 2.1 grams in order to be accepted. What is the range of rejected bag, x, for the bags of pumpkin seeds?
A. 397.9
B. x < 397.9 and x > 402.1
C. x < 400.0 and x> 402.1
D. 400.0 > x < 402.1
Answers
You calculate this by subtracting and adding 5.3 to 500
Option: B is the correct answer.
B. x < 397.9 and x > 402.1
Step-by-step explanation:It is given that:
Each bag is advertised as weighing 400 grams.
Also, a bag must weigh within 2.1 grams in order to be accepted.
Hence, for the bag being accepted the weight must be no less than 2.1 gram from 400 gram and should be no more than 2.1 gram from 400 grams.
i.e. the weight of the bag must be such that:
400-2.1≤ x ≤ 400+2.1
i.e.
397.9 ≤ x ≤ 402.1
Hence, if the weight of the bag is less than 397.9 grams or is more than 402.1 grams then the bag will be rejected.
i.e. The range for the bag being rejected is: x<397.9 grams and x>402.1 grams.

A glass of water was one eighth of a liter. How many glasses would it take to fill up a 3 liter jug
Answers
Final answer:
It would take 24 glasses to fill up a 3 liter jug.
Explanation:
To fill up a 3 liter jug, we need to determine how many glasses of water, each measuring 1/8 of a liter, would be required.
First, we need to find the number of glasses in 1 liter. Since 1 liter is equivalent to 8 glasses (1/8 * 8 = 1), we can divide 3 liters by 1/8 liter to find the number of glasses for 3 liters.
3 liters is equal to 3 / (1/8) = 3 * 8/1 = 24 glasses. Therefore, it would take 24 glasses to fill up a 3 liter jug.

What is the m∠ACB? 10° 50° 90° 180°
Answers
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°
Answer:
50°
Step-by-step explanation:
90 + 4x+ 7x - 20(+20) = 180 + 20
4x + 7x = 200 - 90
4x + 7x = 110
11x/11 = 110/11
X = 10
m∠ACB = 7x - 20 = 7(10) - 20 = 50

The x-intercept is (-2,0).
To solve for the y-intercept, we set x=0. That is

Which it true about modeling a solution to an addition problem on a vertical number line?
A. When adding a negative number, you move down
B. When adding a positive number, you move down
C. Locating the sum is not necessary.
D. Locating the sum is the first step
Answers
Answer:
A. When adding a negative number, you move downStep-by-step explanation:
Actually, according to transformation of functions, there's two types of transformation, those that only involve translation, and those that change the dimension of the function.
In this case, modelling a solution to an addition problem, we know that adding a negative number, the function will move downs, because in that case we will be transformation or "changing" the y-variable, that's why it will move vertically.
Therefore, the right answer is A.
