After he trimmed it, it was [tex]84\frac{3}{8}[/tex] inches tall. This can be solved using expression.
What is an expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Any one of the following mathematical operations can be used i.e. addition, subtraction, multiplication, or division.
There are three different expression types:
There is just one arithmetic value that an arithmetic expression may produce.A character expression evaluates to just one character value.One logical value is produced by the evaluation of a logical or relational statement.The expression becomes:
= [tex]84\frac{5}{8} - [{4 * (\frac{1}{16})][/tex]

Answer: 1/2
Step-by-step explanation:
Number of red balloons = 17
Number of purple balloons = 11
Number of orange balloons = 3
Number of green balloons = 1
Number of yellow balloons = 2
Total number of balloons = 34
The probability that a randomly selected balloon will be red will be:
= Number of red balloons/Total number of balloons

could solve first.
b) How many games, in total, are played
during the season?
Please I need deep explaining.
Therefore , the solution of the given problem of combination comes out to be there were 182 games played in all.
Definition of combinationCombinations are operations in mathematics that count the number of possible combinations that can be created from a set of items, where the selection's direction is immaterial. You are free to select any arrangement of the parts. Permutations and combinations can be mixed up.
Here,
There still are 14 teams in all, but each team plays the other twice.
Every team plays almost every team twice, hence the total amount of games played is simply the permutations of 2 out of 14, which is determined by:
₁₄P₂
=14!/((14-2)!)
= (14×13×12!)/ 12!
= 14×13
=182
Consequently, there were 182 games played in all.
Therefore , the solution of the given problem of combination comes out to be there were 182 games played in all.

The simplified form of radical √18 . 3√5 = 9√10
What is radical?In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol.
For example, ³√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.
Given radical
√18 . 3√5
⇒ √(9 × 2) . 3√5
⇒ 3√2 . 3√5
⇒ 9(√2.5)
⇒ 9√10
⇒ 28.46
Hence, The radical √18 . 3√5 can be simplified to 9√10 having value = 28.46

Let ŷ represent the profit (in thousands of dollars) for a certain company xx years after 1960. A statistician calculates a linear model
ŷ = -1.23 x + 16.07
Use the model to estimate the profit in 1965. Your answer should be in dollars, not thousands of dollars.
Answer:
[tex]\=y =\$9.92[/tex]
Step-by-step explanation:
From the question we are told that:
Number of years [tex]N=1960-1965=>5years[/tex]
Linear model [tex]\=y = -1.23 x + 16.07[/tex]
Therefore Inputting values into the model we have

The perimeter of a rectangle is 84 cm. the length is 3 cm shorter than the width. find the length and width of the rectangle.
Taking into account the definition of a system of linear equations, the length and width of the rectangle is 22.5 cm and 19.5 cm respectively.
System of linear equationsSystems of linear equations are groupings of first degree equations with the same unknowns, of which a common solution must be found.
In the systems of equations, the values of the unknowns must be found, with which, when replaced, they must give the solution proposed in both equations.
Number of sodas and hot dogs soldIn this case, a system of linear equations must be proposed taking into account that:
"x" is the length of the rectangle."y" is the width of the rectangle.You know:
The perimeter of a rectangle is 84 cm. The perimeter of a flat geometric figure is called the length of its contour. It is obtained as a result of the sum of the sides of a flat geometric figureThe length is 3 cm shorter than the width.The system of equations to be solved is
2x + 2y= 84
x= y + 3
The substitution method is a way to solve systems of equations. To use the substitution method, you choose an equation and find an expression for one of the variables in terms of the other variable. Then substitute that expression for the variable in the other equation.
In this case, substituting the second equation in the first one you get:
2×(y+3) + 2y= 84
Solving:
2y+ 2×3 + 2y= 84
2y+ 6 + 2y= 84
2y + 2y= 84 - 6
4y= 78
y= 78÷4
y= 19.5
Replacing this value in the second equation, you get:
x= 19.5 + 3
x= 22.5
Finally, the length of the rectangle is 22.5 cm and the width of the rectangle is 19.5 cm.

Hello, and I am confused on this question I was wondering if anyone could help!
The perimeter of a square room is 80 feet. How many floor tiles 1 foot square would be needed to cover the area of the room
We would require 400 square tiles, each measuring one square foot, to cover the whole surface of the square room.
If the perimeter of the room is 80 feet, we know that all four sides of the square room have the same length. To find the length of each side, we can divide the perimeter by 4: 80 feet / 4 = 20 feet.
Now that we know the length of each side of the room, we can find the area of the room by squaring that measurement: 20 feet x 20 feet = 400 square feet.
To find the number of floor tiles needed to cover the area of the room, we divide the total area of the room by the area of each tile: 400 square feet / 1 square foot/tile = 400 tiles.
So, to cover the entire area of the square room, we would need 400 square tiles of one square foot each.
