The answer is -1 because using the trick rise/run from one point to the next proves it
Let's check if (3 , 6) is the point of intersection of the given lines ~
and
If the point is the point of intersection of these two lines, then it should satisfy both the equations ~
let's try each of them, using x coordinate of point.
So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
Answer:
e) 294 children
Step-by-step explanation:
Since there are 394 children in total and 169 do not like either ice-cream, the number of children who likes at least 1 ice cream is
394 - 169 = 225 children
Out of 225 children, 150 like pistachio icecream, some of them may like both. Therefore the number of children who likes ONLY chocolate icecream is
225 - 150 = 75 children
Similarly, out of 225 children, 175 like chocolate icecream, some of them may like both. Therefore the number of children who likes ONLY pitaschio icecream is
225 - 175 = 50 children
So the total number of children who like at most only 1 kind of ice cream is
75 + 50 + 169 = 294 children
Answer:
equation: 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)
Step-by-step explanation:
countertop mass, m =?
density, ρ = 2.75 g/cm^3
wide, w = 1 m
long, l = 3 m
thick, t = 4 cm
countertop volume, V = w*l*t = 1 m *3 m*4 cm* (100 cm/1 m)^2
Isolating mass from density definition gives
ρ = m/V
m = ρ*V
m = 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)
