Joy makes 6.5 litres of soup, correct to the nearest 0.5 litre. She serves it the soup in 280ml portions, correct to the nearest 10ml. 22 people order this soup, Does joy definitely have enough soup to serve the 22 people

Joy definitely does have enough soup for 22 people.

Step-by-step explanation:

Upper Bound: 285ml  turn it to 0.285l                     10÷2=5

280ml

Lower Bound: 275ml turn it  to 0.275l

Upper Bound: 6.75l                          0.5÷2=0.25

6.5 Litters

Lower Bound:6.25l

6.75÷0.275=24.54 or 25  

6.25÷0.285=21.92 or 22

22 < 25 Joy definitely does have enough soup for 22 people.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
