Answer:

No

Step-by-step explanation:

Diameter= 180cm

Circumference of each table

= πD

= 180π cm

Each table can fit

= 180π ÷70

= 8 guests (nearest whole number)

Since there are 18 tables, total number of guests

= 8(18)

= 144 guests

Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.

Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.

If that was done,

Total circumference

= 180π(18)

= 10179 cm (5 s.f.)

Total number of people

= 10179 ÷70

= 145 people (3 s.f.)

This is incorrect.

Answer:

111 grams

Step-by-step explanation:

fruit: yoghurt: total

2    : 3           :  2+3=5

The total mass is 185

Divide 185/5 = 37

Multiply each number by 37

fruit: yoghurt: total

2*37    : 3 *37  : 5*37

74            111         185

The mass of the yoghurt is 111

Suppose a triangle has sides a, b, and c, and the angle opposite the side of length a is acute. What must be true?
Ket [755]
3pi/7 < pi/2 because 3/7 < 1/2, and pi/2 is a right angle. Conclusion: the angle opposite side a is an acute angle. In this situation the triangle could be a right triangle, in which case C would be true, but it does not have to be a right triangle, so don´t choose C. Similarly, it could be an acute triangle, in which case B would be true, but it does not have to be, so don´t choose B. Also, A says the angle opposite side a is obtuse, which is false. So don´t choose A. That leaves D, which says the angle opposite side a is acute, which we know is true. So the answer is <span>D. b^2 + c^2 > a^2</span>
