Answer:
the side is 5cm
Step-by-step explanation:
You have to make a tape diagram and divide it in to 9 parts because it is 5 out of 9 then you will make a bracket pointing to only 4 parts of the tape diagram then you do 36/9 and it will equal 4 so put 4 in to each part and so 4 x 4 is 16 so the answer is 16 people prefer historical books
<u>Answer:</u>
x ---> 1
y ---> 5
<u>Step-by-step explanation:</u>
We are given paired values for two variables x and y and we are to determine the constant number by which each term is increased such that they are in a proportional relationship.
For x, we have the following paired values:

So here the difference between each consecutive term is 1 so the constant is 1.
And for y, we have:

In this case, the difference between each consecutive term is 5 so the constant is 5.
Answer:e
Step-by-step explanation:
The equation for the submarine is given as y =-240x
Where y is the distance of the descent
x is the time in hours
and -240 is the rate of distance per unit time
To calculate how long it will take this submarine to reach the descent
x = y /-240
