The nottinghamshire research observatory in england calculated that students who attend nottingham technical university spend about £2,760 each in the local economy for a total of £50.45 million. in total, the impact of their spending on the local economy is £63 million. calculate the size of the student spending multiplier.

total strength of the student = 1.24876

Explanation:

individual spend by student is 2,760 pound

total spending = 50.45 million

therefore total student strength is

here this total strength f student act as multiplier.To get total impact multiplier which is constant value is multiplied by total spending..

in the question, total Impact is greater than total spending. Thus:

total strength of the student = 1.24876

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
