Answer:
Ratio of present ages of Sonal and Manoj = 7:5
Let us consider the ages of Sonal and Manoj to be 7x yrs. and 5x yrs. respectively.
After 10 years, ratio of their ages = 9:7
A/q, 7x+10/5x+10 = 9/7
or 9 (5x+10) = 7 (7x+10)
or 45x + 90 = 49x + 70
or 49x - 45x = 90 - 70
or 4x = 20
or x = 20/4 = 5 .
Therefore, present age of Sonal = 7x yrs. = 7 x 5 yrs. = 35 yrs.
present age of Manoj = 5x yrs. = 5 x 5 yrs. = 25 yrs.

Answer:
A. 8
Step-by-step explanation:
The angle shown is a 90 degree right angle (shown by the box where the vertex is)
We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.
After dividing both sides by 5, we get x = 8
Answer: I’m sorry I cannot explain this any other way because I can not see the answers but —> If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line. ✨
Step-by-step explanation: hope it help you later on!
So ur going from a smaller shape to a larger shape....means the scale factor is more then 1. The scale factor is the number that u multiply the original shape by to get the other shape.
so lets look at DE...it is 2.....and D'E' is 6
so 2 * x = 6...with ur scale factor being x
2x = 6
x = 6/2
x = 3.....so the scale factor is 3....because multiplying the original shape by 3, gives u the other shape
D=m/v so d=50/10=5
The density is 5g/ml
It might be ml^3 (5g/ml^3) but I don’t remember
