Find y when x=9 if y varies directly as the square of x, and y=100 when x=5.
Answer:
324
Step-by-step explanation:
Given : y varies directly as the square of x
To Find : Find y when x=9
Solution :
We are given that y varies directly as the square of x
[tex]\Rightarrow y \propto x^2[/tex]
So, [tex]\Rightarrow y= kx^2[/tex] ---1
where k is the constant of proportionality
Now we are also given that y=100 when x=5.
Substitute the values in 1
[tex]100= k(5)^2[/tex]
[tex]100= 25k[/tex]
[tex]\frac{100}{25}=k[/tex]
[tex]4=k[/tex]
So, equation becomes [tex]y= 4x^2[/tex]
Now substitute x= 9
[tex]y= 4(9)^2[/tex]
[tex]y=324[/tex]
Hence The value of y when x is 9 is 324

how can you determine that a coin is not pure silver if you known the mass and volume of the coin?
Answer: By measuring its density which should come out to be [tex]10.5cm^3[/tex] at [tex]20^0C[/tex]
Step-by-step explanation:
Density is defined as the mass contained per unit volume.
[tex]Density=\frac{mass}{Volume}[/tex]
Density of a substance is an intensive property and it does not depend on the amount of matter contained in the substance. It is specific of a compound and thus can be used to know the purity of substances.
Density of silver is [tex]10.5g/cm^3[/tex] at [tex]20^0C[/tex].
Thus if density comes out to be different from the standard value , it means the silver is impure.

What is the clockwise and counterclockwise rule for 180 degrees of rotation?
The right-hand rule is used to determine the direction of angular velocity and angular momentum when an object rotates 180 degrees. If the rotation is counterclockwise, the thumb points up, and if clockwise, it points down.
The Counterclockwise and Clockwise Rules for 180 degrees of rotation are principles used to determine the direction of angular velocity and angular momentum in a rotating system.
When an object rotates counterclockwise as viewed from above, the right-hand rule can be used to find the direction of its angular quantities.
To do this, point your thumb upward while the fingers of your right hand curl in the direction of rotation; your thumb will then point in the direction of the angular velocity vector and angular momentum.
Conversely, if the rotation is clockwise, the thumb would point downward, indicating the opposite direction for angular velocity and angular momentum.
An understanding of these rules is crucial in physics, especially when studying rotational motion and the effects of torque.

M mr. Brown has $410,000 in a retirement account that earns 3.85% interest each year. Find the amount earned each year by his investment. How do you do this I don't understand?
Final answer:
Mr. Brown's retirement account with a principal of $410,000 at an annual interest rate of 3.85% will earn $15,785 each year.
Explanation:
Mr. Brown has an investment in a retirement account with a principal amount of $410,000 that earns an annual interest rate of 3.85%. To calculate the amount of interest earned each year, we can use the simple interest formula:
Interest = Principal × Rate × Time
Since we want to find the interest for one year, Time is equal to 1. Plugging in the numbers:
Interest = $410,000 × 0.0385 × 1
Interest = $15,785
Therefore, Mr. Brown's investment will earn $15,785 per year at an interest rate of 3.85%.

How many yards are in 150 feet?
There are 50 yards in 150 feet.
To convert feet to yards, we need to know that there are 3 feet in a yard. Therefore, to find out how many yards are in 150 feet, we divide the number of feet by the conversion factor of 3.
150 feet ÷ 3 = 50 yards
So, there are 50 yards in 150 feet.
To understand why this conversion works, we can think about the relationship between feet and yards. One yard is defined as 3 feet, meaning it is three times longer than a single foot. Therefore, when we have a certain number of feet, we can divide it by 3 to determine how many times the length of one yard fits into that measurement. In this case, 150 feet can be divided evenly into 50 groups of 3 feet, which gives us 50 yards.
In summary, there are 50 yards in 150 feet, and this conversion is derived from the fact that one yard is equivalent to 3 feet.

Lillian bought 2.52 pounds of tomatoes and 1.26 pounds of lettuce to make salad for 18 people. If each person got the same amount of salad , how much salad did each person get?
Answer:
amount of salad by each person = 0.21 pounds
Step-by-step explanation:
Lilian bought 2.52 pounds of tomatoes and 1.26 pounds of lettuce to make salad for 18 people. That means the combined weight in pounds of tomatoes and lettuce is the weight of the salad.
The weight of the salad = 2.52 + 1.26
The weight of the salad = 3.78 pounds
The total weight of the salad is 3.78 pounds . He shared the weight to 18 people and each person collected the same amount.
To find the amount each person got, we divide 3.78 by 18 people.
amount of salad by each person = 3.78/18
amount of salad by each person = 0.21 pounds

Part 1
If this is true, how much extra profit did it receive per day?
The restaurant received $
450
extra profit per day.
Part 2
If it had, instead, lost $150 per day, how much money would it have lost for the week?
The restaurant would have lost $
1,050
for the week.
Part 3 out of 3
If its total loss was $420 for the week, what was its average daily change?
The restaurant's average daily change was −$
.
Final answer:
The restaurant gained an additional $450 per day with the special item, lost $1,050 if it had lost $150 per day, and an average daily loss of $60 if the total weekly loss was $420.
Explanation:
To calculate the extra profit per day, we divide the total extra profit by the number of days in a week. $3,150 divided by 7 days gives us $450 extra profit per day.
If the restaurant had lost $150 per day instead, we would multiply the daily loss by the number of days in a week. So, $150 times 7 days equals a total loss of $1,050 for the week.
For the last part, if the total loss for the week was $420, to find the average daily change, we divide this amount by 7. Thus, $420 divided by 7 days equals a daily change of -$60.
