The smaller of the two number is 10.
What are Ratios?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.
In simple words, the ratio is the number that can be used to express one quantity as a fraction of the other ones. The two numbers in a ratio can only be compared when they have the same unit. We make use of ratios to compare two things.
Given:
Ratio of two Positive number = 5:6
Let , the smaller number be 5x
then , the bigger number = 6x
According to the question,
product of these numbers = 120
Therefore,

Which of these expense types and answers is true?
a. Fixed expenses - change each month
b. Periodic fixed expenses - are monthly expenses like your water bill and electric or gas bill.
c. Flexible expenses - monthly expenses whose cost is the same each month
d. Indebtedness expense - minimum monthly payments you make on your loans and credit cards
The expense type which is true is , indebtedness expense as because they are the minimum monthly payments you make on your loans and credit card.
Being in debt to someone else or owing them money is the state of being indebted. A person who owes money has either borrowed money or obtained goods or services in exchange for a promise to repay the money.
Someone can owe money for both present-day obligations and obligations that they anticipate having in the future. For instance, the term "indebtedness" can relate to a person's mortgage or a car loan.
The majority of people cannot afford to buy a home or a car outright, thus they owe the bank the amount of the loan that was granted to them. When you use a credit card to make purchases like apparel or travel expenses, you become indebted. Being in debt is not the same as not making payments.

A pet store sells a large dog kennel 98.50 the wholesale cost o the kennel is 63.55 what is the percent of markup round to the nearest percent.
Rounded to the nearest percent, the markup is approximately 55%.
What is the percent markup?
Markup percentage is calculated by dividing the gross profit of a unit (its sales price minus its cost to make or purchase for resale) by the cost of that unit.
To find the percent markup, you can use the following formula:
percent markup = (retail price - wholesale price) / wholesale price * 100
Plugging in the values given, we have:
percent markup = (98.50 - 63.55) / 63.55 * 100 = 34.95 / 63.55 * 100 = approximately 55%

a linear function has slope of -5/3. What does the slope tell us about the graph of the function
Answer:
Step-by-step explanation:
The slope of a linear function is a measure of the rate at which the value of the function changes as the input (x) changes. A slope of -5/3 means that for every 3 units of change in the input, the output (y) changes by -5 units.
In general, a negative slope indicates that the graph of the function is decreasing. As the input increases, the output decreases. A slope of -5/3 is a relatively steep negative slope, which means that the graph of the function will have a steep downward slope.
A slope of -5/3 also tells us that the function is not a horizontal line. A horizontal line has a slope of 0, which means that the output does not change as the input changes. A slope of -5/3 is not equal to 0, which means that the function is not a horizontal line.
Overall, the slope of a linear function tells us about the direction and steepness of the graph of the function. A slope of -5/3 indicates that the graph of the function is decreasing and relatively steep.
Write an equation of the line that passes through $\left(7,10\right)$ and is perpendicular to the line $y=\frac{1}{2}x-9$.
The equation of the line that passes through (7, 10) and its perpendicular to the line y = (1/2)x - 9 is y = -2x + 24
The coordinates of the line passing through the point = (7, 10)
The equation of the perpendicular line
y = (1/2)x - 9
The slope of the line = 1/2
The slope of the original line = - 1 / (1/2)
= -1 × 2
= -2
The slope intercept form is
y = mx + b
Substitute the values in the equation and find the value of b
10 = -2(7) + b
10 = -14 + b
b = 10 + 14
b = 24
Substitute the value of b and m is the equation
y = -2x + 24

What is equation of a line?
The set of points that make up a line in a coordinate system are represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y. The slope of the line and a point on the line can be used to create the equation of a line.
The points on the line are (3,0) and (0,1).
The slope of a line that passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).
The slope of line is (1 - 0)/(0 - 3) = -1/3.
The line cuts y-axis at (0,1). Thus y-intercept of the line is 1.

Submit Answer how do I come up with the number
In the diagram, the length of OP to the nearest tenth is 5.4
How to determine the length?We are to determine the ratio of the sides of the diagram.
The ratio of the sides using the given sides is
Let the unknown side be x
The ratio of the sides is given as follows
25:34 = 15:x+15
Put into fraction we have
25/(25+9)= 15/(x+15)
Cross multiplying we have
25x+375 = 375+135
Collecting like terms
25x=510-375
Simplify further to have
25x=135
Making x the subject
x=5.4
Therefore the length OP is 5.4 units

What is the construction of a quadrilateral PQRS?Generally, To construct a quadrilateral PQRS with the given dimensions, you can use a straightedge and a compass. Here is a step-by-step guide:
Start by drawing a straight line segment PQ of length 5 cm.Place the compass on point P and draw an arc with a radius of 5.5 cm.Place the compass on point Q and draw an arc with a radius of 5.5 cm. The two arcs should intersect at a point R.Place the compass on point R and draw an arc with a radius of 6.5 cm.Place the compass on point P and draw an arc with a radius of 6.5 cm. The two arcs should intersect at a point S.Connect points S and R to complete the quadrilateral PQRS.To construct a triangle QRM with an area equal to quadrilateral PQRS, you can use the same method as above. Here is a step-by-step guide:
Start by drawing a straight line segment QM of length 5 cm.Place the compass on point Q and draw an arc with a radius of 5.5 cm.Place the compass on point M and draw an arc with a radius of 5.5 cm. The two arcs should intersect at a point R.Connect points Q and R to complete the triangle QRM.To verify that the area of triangle QRM is equal to the area of quadrilateral PQRS, you can use the formula for the area of a triangle:
Area of triangle QRM = (1/2) * QM * QR * sin(angle QRM)
And the formula for the area of a quadrilateral:
Area of quadrilateral PQRS = (PQ * QR * sin(angle PQR))/2
Substituting the given values and solving for sin(angle QRM), we find that:
sin(angle QRM) = (2 * area of quadrilateral PQRS)/(QM * QR)
= (2 * (5 * 5.5 * sin(75)))/(5 * 5.5)
= sin(75)
Thus, the area of triangle QRM is equal to the area of quadrilateral PQRS, as desired.
