3. Find the scale factor using the given scale drawings and measurement below
The question asks to find the scale factor for given scale drawings and measurements. A scale factor is computed by creating a ratio comparing the measurement of the scale drawing to the actual measurement, simplifying that ratio to find the scale factor.
Explanation:The subject of the question is concerned with finding the scale factor from a given scale drawing and measurements. In mathematics, particularly in geometry, a scale factor is used to transform the size of a figure without altering its shape.
Step-by-Step ExplanationTo find the scale factor for each given scale drawing, you will need to create a ratio or a fraction that compares the scale measurement to the actual measurement. Here’s how you might solve one of the problems:
Example: What is the scale factor if 3 inches is equal to 12 feet?
Solution:
Convert all measurements to the same unit, for instance, turn feet into inches (1 foot = 12 inches).Write the ratio of the scale drawing to the actual measurement.Reduce the ratio to its simplest form to find the scale factor.Ella has 50 stacks of ten pennies in each stack.

clay is reading a map to decide his vacation route. The map has a scale of 1cm equals 18miles. If he estimates the length of his vacation route on a map is 14 centimeters what is the length in miles
Using the map scale of 1cm equals 18 miles, the actual length of Clay's vacation route is calculated as 252 miles by multiplying 14 centimeters (the length on the map) by 18 miles (the scale conversion factor).
Clay is using a map scale to plan his vacation route. The scale of the map is given as 1cm equals 18 miles. To calculate the actual length of Clay's vacation route in miles, we can set up a simple proportion. Since 1cm on the map represents 18 miles in reality, we multiply the length on the map, which is 14 centimeters, by 18 to find out how many miles this length represents:
Length in miles = 14 cm * 18 miles/cm
After performing the multiplication, we get:
Length in miles = 252 miles
Therefore, Clay’s vacation route is 252 miles long according to the map's scale.

A pair of parallel lines is cut by a transversal:
A pair of parallel lines is cut by a transversal. The interior angle made on the left by the intersection of the upper parallel line and the transversal is divided into 2 parts by a slanting line. One part of this angle is labeled as x, and the other part is labeled as 30 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 75 degrees.
What is the measure of angle x?
Answer:
x = 45°
Step-by-step explanation:
It a transversal line intersect two parallel lines, then alternative interior angles are congruent.
From the below graph it is clear that the line m and n are two parallel lines and l is a transversal line.
[tex]\angle ABC\cong \angle BCD[/tex] (Alternative interior angles)
[tex]m\angle ABC=m\angle BCD[/tex] (Definition of congruent angles)
[tex]x+30^{\circ}=75^{\circ}[/tex]
Subtract 30° from both sides.
[tex]x+30^{\circ}-30^{\circ}=75^{\circ}-30^{\circ}[/tex]
[tex]x=45^{\circ}[/tex]
Therefore the measure of angle x is 45°.

If a project is handed in late you receive 8/9 of your earned points. You received 72 points on your late project. How many points did you lose
In this situation, because the project was handed in late, you lost a total of 9 points. The full score was 81, and you got 72 after a deduction.
Explanation:The principal in this problem is understanding proportion. Given that handing in a project late results in receiving 8/9, or approximately 88.88%, of the total points, we'll figure out the total possible score by dividing the received points (72) by the portion of the full score you got for handing in the project late, which is 8/9. So, 72 ÷ 8/9 = 81. This would be the original points you could have received. You can then subtract the received points (72) from the original points (81) to ascertain the number of points lost. Therefore, 81 - 72 = 9. Consequently, you lost 9 points because the project was handed in late.

rewrite 8/9 with a denominator of 63
Final answer:
To rewrite the fraction 8/9 with a denominator of 63, multiply both the numerator and denominator by 7 to get 56/63.
Explanation:
To rewrite 8/9 with a denominator of 63, you need to find a number that you can multiply both the numerator (8) and the denominator (9) of the original fraction by, so that the denominator becomes 63. To do this, divide 63 by the original denominator, 9, which gives you 7. Thus, the number you need to multiply by is 7.
Multiply both the numerator and the denominator by 7:
Numerator: 8 times 7 = 56
Denominator: 9 times 7 = 63
Therefore, the fraction 8/9 with a denominator of 63 is 56/63.
The value V of a square glass varies directly as the square of its length X cm. If the value of a square glass with length 3 cm is $243, find the value of a glass with length 5 cm
The value V of a square glass varies directly as the square of its length X cm. This means that V is proportional to [tex]X^2[/tex], which can be expressed as:
[tex]\[ V = kX^2 \][/tex]
where k is the constant of proportionality.
Given that the value of a square glass with length 3 cm is $243, we can use this information to find the constant k:
[tex]\[ 243 = k(3)^2 \][/tex]
[tex]\[ 243 = 9k \][/tex]
[tex]\[ k = \frac{243}{9} \][/tex]
[tex]\[ k = 27 \][/tex]
Now that we have the value of k, we can find the value of a glass with length 5 cm by substituting X = 5 into the original equation:
[tex]\[ V = 27(5)^2 \][/tex]
[tex]\[ V = 27 \times 25 \][/tex]
[tex]\[ V = 675 \][/tex]
Therefore, the value of a glass with length 5 cm is $675.
The answer is: 675.
Evaluate 4x-3 when x=_3
To evaluate the expression 4x-3 for x = -3, we substitute -3 into the expression and follow the order of operations, resulting in a value of -15.
Explanation:To evaluate the expression 4x-3 when x is -3, we simply substitute -3 in place of x and calculate the result as follows:
Replace x with -3: 4(-3) - 3.Multiply 4 by -3: -12 - 3.Finally, subtract 3 from -12 to get: -15.Therefore, evaluating 4x-3 when x is -3 gives us -15.

The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 square feet. Let y represent the number of square yards and x the number of square feet. Then y varies directly with x. What is the constant of variation? What is the equation representing the direct variation?
Answer:
Part 1) The constant of variation is [tex]k=1/9[/tex]
part 2) The equation is [tex]y=\frac{1}{9}x[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]
Let
x -----> the number of square feet
y -----> the number of square yards
Three square yards are equivalent to 27 square feet
so
we have the point (27,3)
Part 1) What is the constant of variation?
The constant of variation or proportionality is equal to
[tex]k=y/x[/tex]
substitute the values
[tex]k=3/27[/tex]
Simplify
[tex]k=1/9[/tex]
Part 2) What is the equation representing the direct variation?
we know that
[tex]y=kx[/tex]
substitute the value of k
[tex]y=\frac{1}{9}x[/tex]
This equation shows that the number of square yards (y) is directly proportional to the number of square feet (x) with a constant of variation equal to 1/9.
In direct variation, the relationship between two variables can be represented by the formula:
y = kx
Where:
- y represents one variable (in this case, the number of square yards).
- x represents the other variable (in this case, the number of square feet).
- k is the constant of variation, which remains the same for all data points in the direct variation.
In this specific case, you've mentioned that 3 square yards are equivalent to 27 square feet. You can use this information to find the constant of variation (k). You can choose one of the data points to solve for k. Let's use the point (3, 27):
3 = k * 27
Now, solve for k:
k = 3 / 27
k = 1 / 9
So, the constant of variation (k) is 1/9. The equation representing the direct variation is:
y = (1/9)x
This equation shows that the number of square yards (y) is directly proportional to the number of square feet (x) with a constant of variation equal to 1/9.
