Answer:
A
Step-by-step explanation:
Just add every number and divide by 4. The question is basically asking for average/mean of his previous expenditure.
We have been given that in ΔJKL, the measure of ∠L=90°, KL = 22 feet, and JK = 54 feet. We are asked to find the measure of angle J to nearest degree.
First of all, we will draw a triangle as shown in the attachment.
We can see from our attachment that side KL is opposite side to angle J and side JK is hypotenuse of right triangle.
We know that sine relates opposite side of right triangle to hypotenuse.


Using inverse sine or arcsin, we will get:


Upon rounding to nearest degree, we will get:

Therefore, the measure of angle J is approximately 24 degrees.
Answer: n^3 and a^2
Step-by-step explanation:
It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or
. Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

Where x is the amount of water to be added, in ml (milliliters).
Cross multiplication of the above equation will give us:

Dividing both sides by 2 we will get:

Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.
