answer: 16(1 1/8x3)=y y=54
Step-by-step explanation:
1 1/8x3= 3 3/8
3 3/8x16=54
The length of the three ropes together is 54 feet.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Marco has a rope that is 16 feet long. He ties his rope to Liam and pams with a square knot that uses 1¹/₈ feet of rope.
The length will be calculated as,
E 16(1¹/₈x3)
E = 1¹/₈x3 = 3³/₈
E = 3³/₈x16
E = 54 feet

A sweater is 15% off. The regular price is $24. What is the price after the discount is taken off?
Answer:
$20.40 after the discount
Step-by-step explanation:
To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6
Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40

(my teacher told me to start out with c first, c= an something like that I don’t remember)
Step-by-step explanation:
<c =90 °
So, Pythagoras theorem can be used,
Hypotenuse ² = base ² + altitude ²
AB²=AC²+BC²
11²=AC²+4²
11²-4²=AC²
121-16=AC²
Root 105=AC
AC=10.2 cm
The length of AC is 10.25 cm
What is pythagorean theorem ?
If ΔABC is a right angle triangle, then
AB² = BC²+AC²
where AB = Hypotenuse, BC & AC are adjacent sides of the right angle
What is the required length of the side ?Given, hypotenuse = AB = 11 cm
One of adjacent sides = BC = 4 cm
We have to find the length of AC.
Using pythagorean theorem,
AB² = BC²+AC²
⇒ AC² = AB² - BC²
⇒ AC² = 11²-4²
⇒ AC² = 121-16
⇒ AC = √105
⇒ AC = 10.25
So the length of AC = 10.25 cm

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones, can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.
What expression represents the profit, and what is the profit if 240 cell phones are sold?
40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800
Answer:
Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.
Step-by-step explanation:
The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850
How to calculate profitRevenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40where,
x = number of cell phones sold.
Profit = Revenue - cost
= (2x² + 55x + 10) - (2x² – 15x – 40)
= 2x² + 55x + 10 - 2x² + 15x + 40
Profit = 70x + 50
If x = 240Profit = 70x + 50
= 70(240) + 50
= 16,800 + 50
= $16,850
