A B and C from a triangle where BAC =90 AB = 7.4 mm and CA = 12 and find the length of AC , giving your answer rouned to 1DP

Answers

Question: A B and C form a triangle where BAC = 90°. AB = 7.4 mm and CA = 12 mm. Find the length of BC, giving your answer rounded to 1 DP.

Answer:

14.1 mm

Step-by-step explanation:

From the diagram attached,

Using pythagoras theorem,

a² = b²+c²............... Equation 1

From the attached file,

Given: a = x, b = 7.4 mm, c = 12 mm

Substitute these values into equation 1, and solve for x

x² = 7.4²+12²

x² = 54.76+144

x² = 198.76

x = √(198.76)

x = 14.1 mm

Hence, the length of BC = 14.1 mm

A movie-theater employee notes an inverse relationship between the theater's popcorn sales
and its nacho sales. On a given night, the theater makes 990 from popcorn sales and
$1,892 from nacho sales. If on the next night the employees sell $1,452 of popcorn, how
much is earned from nachos?

Answers

Answer:

Nachos sale on next night = $ 2,776/-

Step-by-step explanation:

Data:-

On a given night theatre makes:

Popcorn sale = $990/-

Nacho Sales = $1,892/-

Next night Theatre makes:

Popcorn sale = $1,452/-

Nacho Sales = x (Let Assume)

Solution:

Given Night = Next Night

Popcorn sale/Nacho sale = Popcorn sale/Nacho sale

990 / 1,892 = 1,452 / x

0.523 = 1,452 / x

x = 1452 / 0.523

x = $2,776/-

What is the area of a circle ?

The formula for the area of a circle

A = πr²

where r is the radius, half the diameter.

For the radius is 12 mm. Using that in the formula gives an area of ...

A = π(12 mm)² = 144 π mm²

For an appropriate value of π, the area is

144 π mm²

For 3.14 as the value of π, the area

The postal service of St. Vincent, an island in the West Indies, obtains a significant portion of its revenues from sales of special souvenir sheets to stamp collectors. The postal service purchases the souvenir sheets from a supplier for $0.80 each. St. Vincent has been selling the souvenir sheets for $8.00 each and ordinarily sells about 80,000 units. To test the market, the postal service recently priced a new souvenir sheet at $7.00 and sales increased to 93,600 units.Required:1. What total contribution margin did the postal service earn when it sold 80,000 sheets at a price of $8.00 each?2. By what percentage did the St. Vincent post office decrease its selling price? By what percentage did unit sales increase? (Round your answers to one-tenth of a percent.)3. What total contribution margin did the postal service earn when it sold 93,600 sheets at a price of $7.00 each?4. What was the postal services increase (decrease) in total contribution margin going from the higher price of $8.00 to the lower price of $7.00?5. How many sheets would the postal service have to sell at the lower price of $7.00 to equal the total contribution margin earned at the higher price of $8.00?

What percentage increase in the number of sheets sold at $7.00 must be achieved to equal the total contribution margin earned at the higher price of $8.00? (Round your answer up to the nearest one-tenth of a percent.)7. A financial manager at the postal service has suggested that a more accurate comparison of the two pricing alternatives ($8.00 vs. $7.00) should include an allocation of the postal services common fixed costs. A portion of the common fixed costs would be allocated to each alternative using total sales dollars as the cost allocation base. He contends that this approach would help ensure that the postal services common fixed costs are covered by the prices that it charges customers. Do you agree?
