So basically right down the graph coordinates for each one for example H is (-4,-1) and just write the opposite for it so H' is (4,1) does that makes sense?
Answer:
B
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 15 and h = 5, thus
A = 15 × 5 = 75 cm² → B
34 + x = 63
x = 63-34
x = 29
Answer:
4 gallons.
Step-by-step explanation:
Reading the top point on the graph we see that 48 gallons of white paint mix with 12 gallons of black Paint.
So 1 gallon of black paint is mixed with 48/12 = 4 gallons of white paint.
Answer: 2 years
Step-by-step explanation:
If Interest= Principal x rate x time/100; then time is (100 × Interest)/(Principal × Rate)
From the question, old Principal is 5600, new principal =6720, the difference is the interest accrued.
Interest = 6720 - 5600 = Rs 1120
Rate = 8% = 8 ÷ 100 = 0.08
Time = x
Then, slot the values into the formula
Time= 100 x 1120 / 6720 x 8
= 112000/53760
=2.08
Time= 2years
I hope this helps
