Golf balls can be purchased in a 3-pack for $4.95 or a 12-pack for $18.95. Which is the better buy? Which Item cost less per gol

natka813 [3]

I think the better buy would be the 12-pack because the quality of the ball and the brand would determine the price. Golf balls do the same thing, you hit than lose it than buy a whole new pack of balls. The 3-pack cost less because it’s $4.95 and the 12-pack cost $18.95. By $14 much.

The area of a trapezium is 31.5 cm². If the parallel sides are of length 7.5 cm and 5.3 cm, calculate the perpendicular distance

spin [16.1K]

Answer:

<h3>The answer is 4.9cm</h3>

Step-by-step explanation:

To find the perpendicular distance between them that's the height we use the formula

$Area \: \: of \: \: a \: \: trapezium = \frac{1}{2} (a + b) \times h$

where

a and b are the parallel sides of the trapezium

h is the perpendicular distance

From the question

Area = 31.5cm²

a = 7.5 cm

b = 5.3 cm

Substituting the values into the above formula we have

$31 .5 = \frac{1}{2} (7.5 + 5.3) \times h$

$31.5 = \frac{1}{2} \times 12.8h$

$31.5 = 6.4h$

Divide both sides by 6.4

$h = \frac{31.5}{6.4}$

h = 4.921875

We have the final answer

<h3>h = 4.9cm</h3>

Hope this helps you

A car loses 20% of its value every

kotegsom [21]

Answer:

See below

Step-by-step explanation:

<u>20% loss a year with initial value of £6000 can be shown as function:</u>

V(t) = 6000*0.8^t

V(t) - is the value after t years

a) t = 1 year

V(1) = 6000*0.8 = £4800

b) t = 3 years

V(3) = 6000*0.8^3 = £3072

c) t = 8 years

V(8) = 6000*0.8^8 = £1006.63

Let's find the value of given expression for x = 5 ~

$\qquad \sf \dashrightarrow \:3(3x + 5)$

$\qquad \sf \dashrightarrow \:9x + 15$

now, plug in the value of x as 5

$\qquad \sf \dashrightarrow \:9(5) + 15$

$\qquad \sf \dashrightarrow \:45 + 15$

$\qquad \sf \dashrightarrow \:60$

so, the equivalent value is 60
