Mr Taylor brought back 180 Euros to the UK. The exchange rate was €1.2 to £1. How much did he get in £ sterling?

Answers

The answer is £150.

This could be calculated using proportion. If £1 is €1.2, how many £ is €180:
£1 : €1.2 = x : €180
x = £1 ÷ €1.2 × €180
x = £150

The cost of a hall rental for a wedding is $500. Each meal at the wedding will cost an additional $45.50 a) Write an algebraic expression equation for the total cost of the wedding.
b) Calculate how many people attended the wedding if the wedding cost totalled $3912.50.

Answers

Answer:

a) 45.50p + 500

b) 45.50p + 500 = 3912.50

p = 70

Step-by-step explanation:

p = number of people

$45.50 for a meal for each person, so:

45.50p

The constant is $500, so let's add that to the expression:

45.50p + 500

Hot Shot Electronics is designing a packing box for itsnew line of Acoustical Odyssey speakers. The box is a
rectangular prism of length 45 centimeters, width
30 centimeters, and volume 81,000 cubic centimeters.
What is the height, in centimeters, of the box?
A. 75
B. 60
C. 48
D. 27
E. 18

Answers

Volume = (length) x (width) x (height)

81,000 = (45) x (30) x (height)

Height = (81,000) / (45 x 30) = 60 cm

V=81 000cm³

V=Ab *h

Ab=L*w

Ab=45*30
Ab=1350cm²

V=1350*h

1350*h=81 000

h=81 000/1 350
h=60cm answer variant b)
