Well the first one you have to divide both sides by 60 to get x.
=60x/60=1500/60
x=25
your answer is 25%
second one...think of it as 18/50. multiply by 2 and you get 36/100
your answer is 36%
Look at the right of the number you want to round then if its greater than 5 round the number that you originally wanted to round. Round it up or down. In this number, 0 is less than 5 so 6 stays the same. all the numbers after 6 turn into zeroes.
Your answer is: 2,600

Answer: 39</h3>
========================================================
Explanation:
You can use the nCr formula shown below

where n = 39 and r = 1. However, you could also use the identity

which basically says there are n ways to pick 1 item if you are given a choice of n items. In this specific case, we have 39 items total, and there are 39 ways to pick one item.
Answer:
Option D
Step-by-step explanation:
From the picture attached,
In the parallelogram ABCD,
Length of diagonals AC and BD are equal.
By the property,
"If the lengths of the diagonals of a parallelogram are equal, parallelogram will be a rectangle".
Therefore ABCD is a rectangle.
That means all interior angles of the given rectangle will be 90°.
Now we apply Pythagoras theorem in right triangle ΔABC,
AC² = AB² + BC²
(22)² = (12)² + (BC)²
484 - 144 = (BC)²
BC = √340
BC = 18.44 inches
Dimensions of the given box are 12 inches by 18.44 inches.
Dimensions of the rectangular tray is 11.5 inches by 18 inches.
Since, dimensions of the box are larger than the dimensions of the tray, tray can be adjusted in the box.
Therefore, Option D will be the answer.
