Drag and drop numbers into the boxes so that the paired values are in a proportional relationship.

1 answer:

7 0

It looks like every x value divided by 5 will result in the y value. For the "x" section, the third one would be 10 because 10/5=2. For the last box in the "y" section, the answer would be 5 because 25/5=5.

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.

Igoryamba

Answer:

Step-by-step explanation:

Joint variation is given by:

$y=kxz$

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

$360=k(4)(10)$

Solving for k:

$40k=360\Rightarrow k=9$

Therefore, our equation is:

$y=9xz$

Then when x = 5 and z = 12:

$y=9(5)(12)=540$

The answer is A.

The side of a square is 11.2 cm. what is the length of the diagonal

Snowcat [4.5K]

You can work out the diagonal by using Pythagoras theorem. (a^2 = b^2 + c^2)

As it is a square, all 4 sides are the same so it would be:
11.2^2 + 11.2^2 = diagonal^2
250.88 = diagonal^2
Square root both sides to get what the diagonal is equal to.
diagonal is 15.8 cm
