9. A restaurant adds a 12% ‘service charge' onto the basic price of meals. How much do
I pay for a meal with a basic price of £8.50?

Overall price after service charge is 9.53

Step-by-step explanation:

8.5 is 10 percent

0.85 is one percent

0.85 multiplied by 2 is 1.70

Add the percentages together and you have 1.03

Then you add that onto the price of the original meal

Tip: $1.02

Total: $9.52

Step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
