24(.22) [Both Sales tax and tip.] = $5.28 Add to the 27. You get $32.28
Or, you could be estimating based on the delivery fee too. Which the would be this:
27(.22) = 5.94 + 27 = 32.94
marco has a rope that is 16 feet long. He ties his rope to liam and pams with a square knot that uses 1 1/8 feet of rope. How long are the three ropes tied together? Write and solve an equation
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

if
[tex]a = \frac{2x + \sqrt{x} }{x} [/tex]
and
[tex]b = \frac{1 - 2 \sqrt{x} }{ \sqrt{x} } [/tex]
without sing a calculator, show that
[tex](a + b) {}^{2} = \frac{4}{x} [/tex]
Answer:
Step-by-step explanation:
Rationalize the denominator of b. So, multiply the numerator and denominator by [tex]\sqrt{x}[/tex]
[tex]b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\[/tex]
Now, find a +b
[tex]a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}[/tex]
Combine like terms
[tex]= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}[/tex]
Now find (a + b)²
(a +b)² = [tex](\frac{2\sqrt{x} }{x})^{2}[/tex]
[tex]= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}[/tex]
Hint: [tex]\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x[/tex]

Is a triangle with side lengths of 5, 10, and 15 a right triangle? Explain
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.

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

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
