150 pupils eat in the school canteen every day. One reckons with around 75g of pasta per person. A: There is spaghetti on Monday. How many kilograms of pasta do you need? B: At the beginning of the month, 50kg of pasta were bought. How often can there be pasta this month?​

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
