After subtracting the cost of one bunch of baby's breath ($3.50) from the total budget ($16), you have $12.50 left for the roses. Since each rose costs $2.50, you can buy 5 roses to complete your bouquet within the budget.
To calculate the number of roses that can be bought, first, we need to subtract the cost of one bunch of baby's breath from the total budget for the bouquet. The cost of one bunch of baby's breath is $3.50. With a total budget of $16, we subtract the cost of baby's breath to see how much is left for the roses:
$16.00 - $3.50 = $12.50
Since each rose costs $2.50, we will divide the remaining budget by the cost of each rose to find out the number of roses that can be purchased:
$12.50 / $2.50 = 5 roses
Therefore, you can buy 5 roses along with one bunch of baby's breath to make up your $16 bouquet.

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

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

3 groups of blanks tenths equals 1.5
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.

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.

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.

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.

A neighbor pays you and two friends $90 to paint her garage. You divide the money three ways in the ratio 2:3:5.
Answer:
First friend gets $18, second friend gets $27, third friend gets $45
Step-by-step explanation:
The ratio means that each person get different quantity.
The total amount must be divided between the 3 persons in the following way
First person gets 2 parts
Second person gets 3 parts
Third person gets 5 parts
If we add all parts, we get 10 parts,if we divide the total payment we get how much is each part, in this case $90 / 10 , so $9
Each part is $9. To get how much will get each friend , we multiple the quantity of parts by the value of them.
First person gets 2 parts, that means $18
Second person gets 3 parts that means $27
Third person gets 5 parts that means $45

Set builder notation is elements of solution set of inequality is greater than 4.
The given inequality is 9t - 4 > 32.
What is set builder notation?A set-builder notation describes the elements of a set instead of listing the elements. For example, the set {5, 6, 7, 8, 9} lists the elements. We read the set {x is a counting number between 4 and 10} as the set of all x such that x is a number greater than 4 and less than 10.
The solution to the inequality 9t - 4 > 32 can be solved as follows:
Add 4 on both the sides of the inequality.
That is, 9t - 4 + 4 > 32 + 4
⇒ 9t > 36
Divide 9 on both the sides of the inequality.
That is, 9t ÷ 9 > 36 ÷ 9
⇒ t > 4

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%.
