Answer:

a) 34.64 inches

b) The TV will not fit inside the TV cabinet

Step-by-step explanation:

Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )

a)If it is 20 inches tall, how wide is the screen ?

We solve using the formula:

Diagonal ² = Width² + Height²

Diagonal = 40 inches

Height = 20 inches

40² = Width² + 20²

Width² = 40² - 20²

Width = √40² - 20²

Width = √(1200)

Width = 34.641016151 inches

Approximately = 34.64 inches

b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?

From the above calculation, the width of the TV = 34.64 inches

Hence the width of the cabinet has to be equal to or more than 34.64 inches

Hence, The TV will not fit inside the TV cabinet

If exactly 194 people sign up for a charter flight, Leisure World Travel Agency charges $312/person. However, if more than 194 p

maw [93]

Title:

<h2>The revenue will be maximum for 253 passengers.</h2>

Step-by-step explanation:

Let, the number of passenger is x, which is more than 194.

In this case, the travel agency will charge [312 - (x - 194)] per passenger.

The total revenue will be $x[312 - (x - 194)] = 506x - x^{2}$ .

As x is the variable here, we can represent the revenue function by R(x). Hence, $R(x) = 506x - x^{2}$ .

The revenue will be maximum when $\frac{d (506x - x^{2} )}{dx} = 0\\2x = 506\\x = 253$ .

Ksenya-84 [330]

<span>Cost of maple syrup = $6.00 a Gallon Cost of corn syrup = 0.80 cents a Gallon Cost of the syrup mixture = $2.36 a Gallon There is mixture of 50 Gallons Lets maple syrup be x gallons, so corn syrup be 50-x gallons Hence, 6*x + 0.80(50-x) = 2.36*50 6x + 40 - 0.8x = 118 5.2x = 78 => x = 78/5.2 => x = 15 So Maple will be syrup be 15 gallons. Corn syrup will be 35 gallons.</span>
