how can you determine that a coin is not pure silver if you known the mass and volume of the coin?
Answers
The density test can be fooled if the coin was adulterated with other metals that average out to the same density as silver, however.
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.
which one of the following uses estimation to check 267-154=113? a. 300-200=100. b. 113+154=267. c. 300-150=150. d. 270-150=120
Answers
A is rounding to the nearest multiple of 100.
267 --> 300
154 --> 200
C is rounding to the nearest multiple of 50.
267 --> 300
154 --> 150
D is rounding to the nearest multiple of 10.
267 --> 270
154 --> 150
Those each give you an estimation of the final answer to see if 113 is a reasonable answer.
Method B is just switching the values around to check the subtraction using addition. That's a valid way to double check the result, but is NOT estimation.
If you are only expected to give *one* answer, then method D is the best way to check using estimation because it does the least amount of rounding.
Answer:
D. 270 - 150 = 120
b. 113 + 154 = 267 is a way of estimation to check 267 - 154 = 113.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given a numerical expression 267 - 154 = 113.
The correct elimination is we must add 154 to both sides to eliminate 154 on LHS and add 154 on RHS.
∴ 267 - 154 = 113 is
267 + 154 - 154 = 113 + 154,
113+154=267

How many yards are in 150 feet?
Answers
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.

Answers
The value of each blank tenth is 0.5 for the 3 groups of blanks.
To solve this problem, we can set up an equation. Let's use 'x' to represent the number of blanks tenths.
An expression in mathematics is a grouping of digits, variables, operators, and symbols that depicts a connection or calculation. It may consist of a single phrase or a group of terms joined together by operators.
The problem states that 3 groups of blank tenths equals 1.5. This can be written as 3x = 1.5.
To isolate x, we divide both sides of the equation by,
3x/3 = 1.5/3.
x = 0.5.

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?
Answers
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
Find y when x=9 if y varies directly as the square of x, and y=100 when x=5.
Answers
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

What is the clockwise and counterclockwise rule for 180 degrees of rotation?
Answers
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?
Answers
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%.

If its total loss was $420 for the week, what was its average daily change?

Answers
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.
