Angharad had an operation costing $500 She was in hospital for x days The cost of nursing care was $170 for each day she was in

Ket [755]

Answer:

a) Total cost = $500 + 170x$

b) 11 days

Step-by-step explanation:

Given:

(a)

Number of days in hospital = $x$

Cost of operation = $ 500

Cost of nursing per day = $170

∴ Cost of nursing for $x$ days = $ $170x$

Therefore, the expression for total cost of her operation and nursing care is given as,

$C=500+170x$ , where $C$ is the total cost.

(b)

Given:

Total cost of operation = $C=\$ 2370$

Using the expression obtained in (a), we solve for $x$ .

$C=500+170x$

Plug in 2370 for C and solve for $x$ . This gives,

$2370=500+170x\\ 170x=2370-500\\ x=\frac{1870}{170}\\x=11$

Therefore, Angharad stayed in hospital for 11 days.

An official stands 2 meters from the edge of a discus circle and 3 meters from a point of tangency How far is the official from

Pachacha [2.7K]

Answer: 3.25 m

Step-by-step explanation:

as a tangency and a radius make a right angle, we can use Pythagoras.

c² = a² + b²

(r + 2)² = r² + 3²

r² + 4r + 4 = r² + 9

4r = 5

r = 1.25 m

so the official is standing 1.25 + 2 = 3.25 m from the center of the circle

This makes sense as a standard discus throwing circle is 2.5 m dia.
