Step-by-step explanation:
Over the course of a year, a tractor-trailer commutes 160,000 miles across America.
a. Assuming a trucker changes his tires every 40,000 miles, and that he starts with a brand new set of tires, how many sets of tires will he use in a year?
b. If the trucker changes the oil every 10,000 miles, and he starts the year with a fresh oil change, how many times will he change the oil in a year?
Answer:
a. 4 sets of tires in a year.
b. 17 times a year.
Step-by-step explanation:
a. I just divided 160,000 by 40,000 to get 4 sets a year.
b. I divided 160,000 by 10,000 and then added 1 to get 17 times a year. I added one because the problem said that the trucker changes the oil in the beginning of the year.

Please help meeeee I'll give 9 points. Describe a sequence of translations, rotations, and reflections that take the lower left triangle to the upper right triangle.
Answer:
A rotation or a reflection and a translation
Step-by-step explanation:
Ik I'm 2 years late but still.
The required angle of rotation is 180° and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.
Given that,
To describe a sequence of translations, rotations, and reflections that take the lower left triangle to the upper right triangle.
Incongruent geometry, the shapes that are so identical. can be superimposed to themselves.
Here,
To shift the lower left triangle to the upper right,
First It must rotate by an angle of rotation of 180° around the center of the geometry, Or it must reflect to the left diagonal.
Thus, the required angle of rotation is 180°, and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

(4.67) (9.8)
(7.3) (8.52)
Answer:
(13.2)(4.5)
Step-by-step explanation:
This is correct because you know that you could round one up, and one down. You know that 12*5 = 60, so you could estimate that these would have a product of 60.

why do we learn properties of real numbers?
answer quick :D
Answer:
The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.

First, you have to distribute the 1/3. To do this, you can either multiply everything in the parentheses by 1/3 or you can divide it all by 3. I will use the division method, so 24x/3 is 8x and -9/3 is -3, so now the expres

You work for the National Weather Service and are asked to study the average daily temperatures in Anchorage, Alaska. You calculate the mean of the average daily temperatures for each month. You decide to place the information on a graph in which the date is the input and the temperature is the output. You also decide that January 1950 will correspond to the month 0 as indicated by the dot on the input scale.
On a coordinate plane, quadrants 1, 2, 3, and 4 are labeled. Month is on the x-axis and degrees Fahrenheit is on the y-axis.
Determine the quadrant in which you would plot the points that correspond to the following data:
The average daily temperature for July 1910 was 71 degreesF.

Kate is going to the fair with three of her friends. It will cost $5.00 to get in and an additional $2 per ride. Create an equation to represent the cost for the whole group and then use the distributive property to expand the expression and solve the problem.
Expression: (4*5)+(2*5)=30
So I have the expression I just need to do the distributive property and I don't understand how to do that.
Answer:
5 * ( 4 + 2 ) = 5 * 6 = 30
Step-by-step explanation:
(5*4) + (2*5) = 20 + 10 = 30
5*4 = 4 people need to pay $5
2*5 = $2 for 5 rides
Distributive Property:
(5*4) + (2*5) = 5 * ( 4 + 2 )
5 * ( 4 + 2 ) = 5 * 6 = 30
Answer:
$40Step-by-step explanation:
Ok, so the distributive property allows us to apply a number evenly over a whole set of numbers.
Equation: 4 (2 x 5) (we distribute the 4 to all terms, since each person experiences those charges.) The answer is $40 for the whole group.
