Answer:Let x = pay per hour as a carpenter and y = pay per hour as a blacksmith
Last week she worked 12 hours as a carpenter
earning 12x dollars
and 20 hours as a blacksmith
earning 20y dollars
and earned a total of $860
and those two things add up to 860.
Do the same with the other sentence, giving you a second equation.
Step-by-step explanation:
Answer:
let the breadth of room be 'x'm
so the lenghth of room is 'x+8'm
Given
Area of room=48m²
i.e length ×breadth =48m²
or,(x+8)x=48
or,x²+8x-48=0
or,x²+12x-4x-48=0
or,x(x+12)-4(x+12)=0
or,(x+12)(x-4)=0
Either x+12=0
or,x=-12(which is not possible)
Or,x-4=0
or,x=4
Thus,breadth is 4m.
length=x+8=4+8=12m
The dimensions of room are 8m and 12m respectively.
I think its y=x-9
sorry if im wrong :(
Answer:
The correct option C:
C) S → R: If he stays home, then it will rain.
Step-by-step explanation:
There are three main transformation for an if-then statements. These three are names are converse, inverse and contrapositive.
If the statement is given:
R → S: "If it rains, then he will stay home."
Then its Converse will be:
S → R: If he stays home, then it will rain.
Its Inverse will be:
∼R → ∼S: If it doesn't rain, then he won't stay home.
Its Contrapositive will be the inverse of the converse.
Answer:
D. 8
Step-by-step explanation:
Draw segment CQ which will be perpendicular to tangent PR.
So, triangle CQR will be right angled triangle right angle at Q.
Let radius of the circle be r.
Therefore,
CQ = CS = r
By Pythagoras Theorem:
