Answer: what grade is this
Step-by-step explanation:
Answer:
20 is 10% of 200
Step-by-step explanation:
We have, 10% × x = 20
or,
10
100
× x = 20
Multiplying both sides by 100 and dividing both sides by 10,
we have x = 20 ×
100
10
x = 200
If you are using a calculator, simply enter 20×100÷10, which will give you the answer.
The correct answer is A shift down two units

Answer:
11:18
Step-by-step explanation:
Here, we are interested in calculating the ratio of diameter of ball A to that of ball B
what to do here is to ensure that both diameters have measurements that are same units.
Thus, mathematically;
44 mm to 7.2cm
But, mathematically;
10 mm = 1 cm
Thus 7.2cm = 7.2 * 10 = 72mm
Thus, our ratio becomes;
44:72
divide through be 4, we have
44/4 : 72/4
= 11 : 18
