3 13/24
Hope this Helps!
To find the difference between 7 1/6 and 3 5/8, convert each mixed number to an improper fraction with a common denominator of 24, subtract the numerators to find 85/24, which simplified to a mixed number results in 3 13/24.
Explanation:The difference between 7 1/6 and 3 5/8 can be found by converting each mixed number to an improper fraction with a common denominator and then subtracting the two. First, convert the mixed numbers to improper fractions. So, we have 7 1/6 as 43/6 and 3 5/8 as 29/8. To find a common denominator, we can use the least common multiple (LCM) of 6 and 8, which is 24. Then we convert the fractions as follows:
43/6 becomes 172/2429/8 becomes 87/24Now we can subtract the numerators and keep the common denominator:
172/24 - 87/24 = 85/24
To present the answer as a mixed number, we divide 85 by 24, which gives us:
3 13/24
Therefore, the difference between 7 1/6 and 3 5/8 is 3 13/24.

In any given year, a factory has a 20% probability of having an accident. About every how many years might the factory expect to have an accident?
Every 1 year
Every 2 years
Every 5 years
Every 20 years
Answer:
Probability of having an accident = 20% o 0.2
Thus,
Expected number of years = 1/probability of accident = 1/0.2 = 5
Hence,
3. Every 5 years is the correct option.
Step-by-step explanation:
The factory will expect to have an accident every 5 years.
The probability of having an accident in the factory = 20% = 20/100 = 0.2
It should be noted that the highest likelihood for an event happening is 100% which is represented by 1.
Therefore, the number of years that the factory expect to have an accident will be:
= 1 / probability of having an accident
= 1/0.2
= 5 years
In conclusion, the factory will expect an accident every 5th year.

What is the equation of a circle with a center of (-2, -1) and radius of √2?
Answer:
(x + 2)² + (y + 1)² = 2
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
Here (h, k) = (- 2, - 1) and r = [tex]\sqrt{2}[/tex], thus
(x - (- 2))² + (y - (- 1))² = ([tex]\sqrt{2}[/tex] )², that is

Explain why receiving a 15% discount is the same as finding 85% percent of the original cost of an item. Then, explain how the mathematical properties and equivalent expressions helped them understand and solve the problem. Please answer!!
Answer:
15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%
Let X be the naked price
Paid = marked price - discount
Paid = X - (15/100 × X)
Using distribution property,
Paid = X(1 - 15/100)
Paid = X[(100-15)/100]
Paid = X(85/100)
Which is 85/100 × X
Hence 85% of X
Answer: 85% = 0.85
While 15% = 0.15
Step-by-step explanation:
Percentage is a fraction whose denominator is 100. So if we say 15%, we mean 15/100 = 0.15.
If want to find 15% of a 100, it means 15% of 100 = 15/100 × 100 = 15.
To find 85 % of 100 means 85/100 × 100= 85
hence subtraction of 15% from 100% is 85%
Therefore 15% = 15/100 = 0.15
While 85% is 85/100 = 0.85

Answer: 3/4
Step-by-step explanation:
To take this ratio to its simplest form, we have to divide by a value divisible by the numerator and denominator.
3 is a divisible value, therefore,
9/12 = 9 ÷ 3 = 3
12 ÷ 3 = 4
Thus, 9/12 = 3/4

Find the zeros of the function.
Write the smaller solution first, and the larger solution second.
g(x)=(-5x– 1)(2x + 8)
smaller x=
larger x =
Answer:
x = - 4, x = - [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
To find the zeros let g(x) = 0, that is
(- 5x - 1)(2x + 8) = 0 ← in standard form
Equate each factor to zero and solve for x
- 5x - 1 = 0 ( add 1 to both sides )
- 5x = 1 ( divide both sides by - 5 )
x = [tex]\frac{1}{-5}[/tex] = - [tex]\frac{1}{5}[/tex]
2x + 8 = 0 ( subtract 8 from both sides )
2x = - 8 ( divide both sides by 2 )
x = - 4
Thus
smaller x = - 4
larger x = - [tex]\frac{1}{5}[/tex]
What is 2 times the difference of 73 and twice the sum of 9 and 4?
This results in a final answer of 94.
The question asks for the calculation of 2 times the difference of 73 and twice the sum of 9 and 4. Let's break it down step by step:
First, calculate the sum of 9 and 4, which is 9 + 4 = 13.Next, multiply this sum by 2 to get twice the sum, which results in 13 imes 2 = 26.The difference between 73 and the result from step 2 is 73 - 26 = 47.Finally, multiply that difference by 2 as per the question, giving us 47 imes 2 = 94.Therefore, 2 times the difference of 73 and twice the sum of 9 and 4 equals 94.
Just I need is solve for x.
Answer:
x=6
Step-by-step explanation:
Since the figure has 4 sides, the total of all of the angles add to 360 as:
180(n-2)=T
180(4-2)=T
180(2)=T
360=T
Now we can set up an equation and solve for x:
17x+8+74+110+66=360
17x+258=360
17x=102
x=6
So x=6

The algebraic expression '3s + 2.15' can represent a real-life situation where you're shopping for food. If sandwiches cost $3 each and a soda costs $2.15, the total you'd spend on 's' sandwiches and one soda is 3s + 2.15 dollars.
Explanation:Here is a scenario that could represent the expression 3s + 2.15: Imagine you're in a store and each sandwich costs $3.00. You're planning to buy 's' number of sandwiches. Now, let's say you also want to buy a soda which costs $2.15. The total cost you will spend in the store would be the cost of the 's' sandwiches plus the cost of the soda, which can be represented by the expression 3s + 2.15. So if you bought 2 sandwiches, the total cost would be 3*2 (for the sandwiches) + 2.15 (for the soda) = $8.15.

Quadrilateral ABCD is inscribed in this
circle.
What is the measure of angle A?
Enter your answer in the box.
The measure of angle A is 88°.
Solution:
Given data:
∠A = (2x – 40)°, m∠B = 116° and ∠D = x°
A quadrilateral inscribed in a circle is called cyclic quadrilateral.
∠B and ∠D are opposite angles in a cyclic quadrilateral.
In cyclic quadrilateral, opposite angles are supplementary.
⇒ m∠B+ m∠D = 180°
⇒ 116° + x = 180 °
Subtract 116° from both sides of the equation, we get
⇒ x = 64 °
To find the measure of angle A:
m∠A = (2x – 40)°
= 2(64°) – 40°
m∠A = 88°
Hence the measure of angle A is 88°.

Regina is tying a bow around a soccer ball to give to her sister. The ball has a radius of 4.5 inches. If the ribbon needs to be 10 inches longer than the circumference of the ball so she has enough room to tie a bow , how many inches of ribbon will she need?
The circumference of the soccer ball can be found using the formula for the circumference of a circle, to which 10 inches is then added to find the total length of the ribbon Regina needs.
Explanation:The problem involves understanding the mathematical concept of circumference. The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the soccer ball has a radius of 4.5 inches. Therefore, the circumference of the soccer ball would be C = 2π(4.5) inches.
Then, the problem states that the ribbon needs to be 10 inches longer than the circumference of the ball. So the total length of the ribbon that Regina needs is C + 10 inches. By substituting the values, we get the length of the ribbon needed.
