Step-by-step explanation:
All statements are correct for two congruent trianglesStep-by-step explanation:If two triangles are congruent than the rules states thatTriangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.As the fig shows two triangleΔ PQRΔ LMNAll three corresponding sides of triangle are congruentall three corresponding angles are congruentBoth triangle are of same sizeBoth are of same shapehence all the statements are CORRECT Keywords:Geometry
Answer:
the number of cups is kept within other till the cups reach reach 50cm
x=number of cups
y= height of the cups when placed on each other
so the equation would be ; x + y=50

lets do this step by step.
First: we need to break this into to prisms.
Next lets say the dimensions:
4 x 2 x 1 and 2 x 2 x 1
now we multiply them and then add them
8 + 4 = 12
volume = 12 cubic units.
it's 8,
let the no. of tired students be x
add all the numbers of the happy, hungry and in between students and then subtract from the total of the student
which has to look smth like this
happy = 10
so we fill all the numbers in between then we add them and see what's missing
1+3+2 = 6
10-6 = 4
4 students are happy
hungry = 7
1+1+3 = 5
7-5 = 2
2 students are hungry
and lastly for tired, they didn't mention the total so we add all the numbers we got and subtract them by the total of students (just like mentioned above)
2+1+1+3+4+2 = 13
21-13 = 8
8 students were tired
x = 8
Use substitution.
y = 2 - x and y = 4x + 7 can become
2 - x = 4x + 7
Now solve for x
-5 = 5x
-1 = x
Now plug -1 for x in either equation.
y = 2 - x -> y = 2 - (-1) -> y = 3
y = 4x + 7 -> y = 4*-1 + 7 -> y = -4 + 7 -> y = 3
So C) is the correct answer.
