Strike441 [17]

<em><u>Option E</u></em>

<em><u>The expression show how much pizza Marcus ate in total is:</u></em>

Total = \frac{1}{2} + \frac{1}{3} \times \frac{1}{2}

<em><u>Solution:</u></em>

Given that,

Marcus ate half of a pizza on Monday night

He then ate one third of the remaining pizza on Tuesday

Therefore,

Monday\ night = \frac{1}{2}\\

Remaining is given as:

Remaining = 1 - \frac{1}{2} = \frac{1}{2}

He then ate one third of the remaining pizza on Tuesday

Therefore,

Tuesday = \frac{1}{3} \times \frac{1}{2}

<em><u>Thus expressions show how much pizza Marcus ate in total is:</u></em>

Total = monday night + tuesday

Total = \frac{1}{2} + \frac{1}{3} \times \frac{1}{2}

Thus Option E is correct

A coat cost $ 131.61 with 9.5% sales tax
marysya [2.9K]

Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost. Multiply retail price by tax rate

Let's say you're buying a $100 item with a sales tax of 5%. Your math would be simply: [cost of the item] x [percentage as a decimal] = [sales tax]. That's $100 x .

Which expression is equivalent to sec^2x − 1? a. cot2x b. tan2x c. csc2x d. cos2x
Nesterboy [21]
Sec^2 x - 1 = tan^2x

Proof:
Sec^2x = 1+ tan^2x

1/cos^2x = 1 + sin^2x/cos^2x

<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting : 
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
