Answer:
B. 12
Step-by-step explanation:
3/4 can be converted to something over 16. You have to multiply 4 x 4 to get to 16, so do the same with 3, and 3 x 4 is 12. Now the fraction/proportion is 12/16, so they will win 12 games.
Answer:
B
Step-by-step explanation:
3/4 of 16 is 12 set a relation 3/4 = x/16. 4 x 4 is 16 so multiply 3 x 4 and you get 12 or you can ask siri "what is 75 percent of 16"

Natalie is opening a clothing store. She plans to start by selling gym shorts. It
costs her $7 for each pair of shorts, $3 per box for the shorts, and $0.25 a
bag. Natalie also spends $650 on rent, $55 on electricity, and $20 on
advertising each month. What is the cost function for Natalie's clothing store
per month?
A. C= 10.25n+ 725
B. C = 7.00n + 725
C. C = 725n+ 10.25
D. C = 7.25n+ 725
O
Answer:A
Step-by-step explanation:
The cost function for Natalie's clothing store per month is C = 10.25n + 725.
Explanation:The cost function for Natalie's clothing store per month can be calculated by adding up all the costs she incurs. This includes the cost of the gym shorts, the cost of the boxes for the shorts, the cost of the bags, and the monthly expenses for rent, electricity, and advertising.
The cost of each pair of shorts is $7, the cost of each box is $3, and the cost of each bag is $0.25. The monthly expenses are $650 for rent, $55 for electricity, and $20 for advertising.
Therefore, the cost function for Natalie's clothing store per month can be expressed as: C = 7n + 3n + 0.25n + 650 + 55 + 20, where n represents the number of gym shorts sold.
Simplifying the expression, we get: C = 10.25n + 725

15-5x < -2x+6 .... distribute
15-5x+5x < -2x+6+5x ... adding 5x to both sides
15 < 3x+6
15-6 < 3x+6-6 ... subtracting 6 from both sides

Ken wants to build a table and put a border around it. The table and border must have an area of 3,276 square inches. The table is 36 inches wide and 72 inches long without the border. Which quadratic equation can be used to determine the thickness of the border, x? (2 points)
Group of answer choices
4x2 + 216x + 2,592 = 0
4x2 + 216x − 684 = 0
2x2 + 216x − 3,276 = 0
x2 + 108x + 3,276 = 0
Answer:
4x2+216x-684x
Step-by-step explanation:
solnA) The dimensions of the table are in inches
Let
x=the thickness of the border
we know that the table and the border must have an area of 3,276 square feet
convert the dimensions of the table to feet
remember that; 1ft =12in
36in=3ft
72in=6ft
i.e; 3,276 = (6+12x)*(3+2x)
solve for x
3276=6×3+ 6×2x +2x×3+ 4x²
3276=18+12x+6x+4x²
4x²+18x+18-3276=0
4x²+18x-3258
solnB) The dimensions of the table are in feet
Let
x=the thickness of the border
we know that the table and the border must have an area of 3,276 square feet
i.e 3,276 = ()×()
solve for x
3,276 = 72×36 + 72×2x + 2x×36 + 4x²
3,276 = 2,592 + 144x + 72x + 4x²
4x² + 216x + 2,592 + 3276 = 0
4x²+216× - 684= 0
therefore; the quadratic equation can be used to determine the thickness of the border =
4x² + 216x - 684 = 0

The area of a rectangle is 344 square inches. If the rectangle is 16 inches wide, find the perimeter of the rectangle.
A. 67 inches
B. 72 inches
C. 75 inches
D. 80 inches
Answer:
C. 75 inches
Step-by-step explanation:
well if it's a rectangle then we would do A = L x W we are told the Width and the Area
344 = L x 16
344 / 16 = 21.5
P = L + L + W + W
16 + 16 + 21.5 + 21.5
16 + 16 = 32
21.5 + 21.5 = 43
32 + 43 = 75
the perimeter is 75 inches
Final answer:
To find the perimeter of the rectangle, we calculate the length by dividing the area by the width and then apply the perimeter formula. We find that the length is 21.5 inches and the perimeter is 75 inches.
Explanation:
To find the perimeter of the rectangle when the area is 344 square inches and the width is 16 inches, we need to use the area formula of a rectangle, which is Area = length × width. Since we have the area and the width, we can calculate the length:
Divide the area by the width to find the length: Length = 344 sq in / 16 in = 21.5 in.
Now, use the perimeter formula: Perimeter = 2 × (length + width).
Substitute the length and width into the formula: Perimeter = 2 × (21.5 in + 16 in) = 2 × 37.5 in = 75 inches.
The correct answer is C. 75 inches.

(b +4)(b +9)(c -5)(c +9)(k +2)(k +3)Step-by-step explanation:
Consider the product ...
(x +a)(x +b) = x^2 +(a+b)x +ab
You will notice that the linear term (a+b)x has a coefficient (a+b) that is the sum of the factors of the constant term (ab).
For problems like this, it is useful to be able to factor the constant term, so you can choose the factors with the appropriate sum.
Signs are important. If the constant is positive, its factors will have the same sign, both positive or both negative. If the constant is negative, its factors will have opposite signs.

P(D|F) = 6/34
Similarly:
P(E|D) = 7/25
P(F|E) = 8/18
Thus, the probability of P(D|F), P(E|D), and P(F|E) are 6/34, 7/25, and 8/18 options (A), (B), and (D) are correct.

Five years ago, Nina was twice as old as Sam. In five years, she will be 1.5 times as old as Sam. How old are Nina and Sam now?
Answer:
age of Sam= 15 years
age of Nina = 25 years
Step-by-step explanation:
Let Nina's age be X years
Let Sam's age be Y years
Five years ago Nina's age will be X- 5 years
Five years ago Sam's age will be Y- 5 years
Given in question
Five years ago, Nina was twice as old as Sam
writing it mathematically using X and Y we have
Nina's age = 2 * Sam's age
X- 5 = 2 *(Y- 5)
X = 2 *(Y- 5) + 5 = 2Y - 10 + 5 = 2Y - 5 _________________equation A
__________________________________________________________
Five years in future Nina's age will be X+ 5 years
Five years ago Sam's age will be Y+ 5 years
Given in question
In five years, she will be 1.5 times as old as Sam
writing it mathematically using X and Y we have
Nina's age = 1.5 * Sam's age
X+5 = 1.5 *(Y+ 5)
X = 1.5*(Y+5) -5 = 1.5Y +7.5 - 5 = 1.5Y +2.5 _________________equation B
_______________________________________
in equation A we have X = 2Y - 5
in equation B we have X = 1.5Y + 2.5
equating equation A and B we have
2Y - 5 = 1.5Y +2.5
=> 2Y - 1.5Y = 2.5 + 5
=> 0.5Y = 7.5
=> Y = 7.5/0.5 = 15
from equation A we have
X = 2Y - 5 (substituting the value of Y = 15 in equation we have)
X = 2*15 - 5 = 25
Therefore age of Sam= 15 years
age of Nina = 25 years

28 m
EX
Answer:
87.92 m
Step-by-step explanation:
The formula to calculate the circumference of the circle is:
Diameter * Pi ----> 28 * 3,14
Final answer:
The circumference of a circle with a 28 meter diameter is calculated using the formula C = \\(pi) \\times d, resulting in 87.92 meters as the circumference.
Explanation:
The question requires us to find the circumference of a circle given its diameter, which measures 28 meters. To calculate the circumference, we use the formula C = \\(pi) \\times d, where \\(pi) is approximately 3.14 and d is the diameter of the circle. Since the diameter is 28 meters, the circumference is calculated as follows:
C = 3.14 times 28 m = 87.92 m.
Therefore, the circumference of the circle is 87.92 meters.
