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/-

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

How long is a string reaching from the top of a 13-ft pole to a point on the 3 points ground that is 7 ft from the base of the pole?

Answers

Answer:

14.76 ft

Step-by-step explanation:

L²= 13² + 7²

L² = 169 + 49 = 218

L = √218 = 14.76 ft

Answer:

14.8

Step-by-step explanation:

We use the Pythagoras theorem because the string and the pole are making a right angle triangle

7^2+13^2=c^2

49+169=c^2

218=c^2

14.8=c
