Kim rode her bicycle 135 miles in 9 weeks riding the same distance each week. Eric rode his bicycle 102 miles in 6 weeks, riding the same distance each week. Which statement correctly compares the number of miles per week they rode?
A.) Eric rode 2 more miles per week than Kim rode
B.)Kim rode 3 more miles per week than Erick rode
C.) Kim rode 11 more miles per week than Erick rode
D.) Eric rode 17 more miles per week than Kim rode
Answer:
The answer is the option A
Eric rode [tex]2[/tex] more miles per week than Kim rode
Step-by-step explanation:
Step 1
Find the number of miles that Kim rode per week
Divide the total miles by the total weeks
so
[tex]\frac{135}{9}\frac{miles}{weeks}= 15\frac{miles}{week}[/tex]
Step 2
Find the number of miles that Eric rode per week
Divide the total miles by the total weeks
so
[tex]\frac{102}{6}\frac{miles}{weeks}= 17\frac{miles}{week}[/tex]
Step 3
Compare the unit rates
Kim [tex]15\frac{miles}{week}[/tex]
Eric [tex]17\frac{miles}{week}[/tex]
[tex]17\frac{miles}{week}-15\frac{miles}{week}=2\frac{miles}{week}[/tex]
so
Eric rode [tex]2[/tex] more miles per week than Kim rode

We know in right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.
Given, A ladder is placed 7 feet from the base of a building and reaches a point on the building that is 24 feet above the ground.
So, The base is 7 feet and the height is 24 feet.
Therefore,
Hypotenuse² = Base² + Height².
Hypotenuse = [tex]\sqrt{49 + 576}[/tex].
Hypotenuse = [tex]\sqrt{625}[/tex].
Hypotenuse = 25 feet.

Calculate the resistance of a piece of aluminum wire with a diameter of 100 mils and a length of two miles, at 68°F. Hint: Be sure to first convert mils to cmils and use the K value for aluminum found in the reference. (Round the FINAL answer to two decimal places.)
The resistance of the aluminum wire with a diameter of 100 mils and a length of two miles is 0.20 ohms.
Explanation:To calculate the resistance of a piece of aluminum wire, we first need to convert the diameter from mils to cmils. 1 mil is equal to 1000 cmils. So, a diameter of 100 mils is equal to 100,000 cmils. Next, we need to use the K value for aluminum, which is 1.82 ohms * cmil/ft. We convert the length of the wire from miles to feet, which gives us 10560 feet. Now, we can calculate the resistance using the formula:
Resistance = (K * Length) / Area
Where K is the conductivity of aluminum, Length is the length of the wire in feet, and Area is the cross-sectional area of the wire in cmils. Plugging in the values, we get:
Resistance = (1.82 * 10560) / 100000 = 0.1957 ohms
Therefore, the resistance of the aluminum wire is 0.20 ohms.
The resistance of the aluminum wire with a diameter of 100 mils and a length of two miles, at 68°F, is 0.0002784 ohms.
To calculate the resistance of the aluminum wire, we need to convert the diameter from mils to cmils. 1 mil is equal to 1000 cmils.
So, the diameter of the wire in cmils would be 100 * 1000 = 100,000 cmils.
Next, we need to use the K value for aluminum, which is 2.65 micro-ohm cmil/foot. We need to convert the length of the wire from miles to feet. 1 mile is equal to 5280 feet.
So, the length of the wire in feet would be 2 * 5280 = 10,560 feet.
Now, we can calculate the resistance using the formula R = (K * L) / A, where R is the resistance, K is the K value for aluminum, L is the length of the wire in feet, and A is the cross-sectional area of the wire in cmils.
Plugging in the values, we get R = (2.65 * 10^(-6) * 10560) / 100000 = 0.0002784 ohms.

How are these four types of transformation similar to each other? How do they differ? In particular, what is one major difference between dilations and the other three types of transformations?
Final answer:
Geometric transformations include translations, rotations, reflections, and dilations; while the first three preserve figure size and shape, dilations change the size of the figure by a scale factor.
Explanation:
Geometric transformations include translations, rotations, reflections, and dilations, all of which change a figure's position and/or size on the plane while maintaining the straightness of lines and parallelism where applicable. These transformations are similar in that they can be applied to geometric figures to alter their position or size within a coordinate system. A major difference between dilations and the other transformations is that dilations change the size of the figure but do not preserve angles and lengths in the same way as the others. A dilation either enlarges or shrinks a figure by a scale factor from a central point, while translations, rotations, and reflections do not alter the size of the figure, only its position or orientation.
