Answer:
Step-by-step explanation:
He traveled at 60 mph a distance of 60*hours.
He traveled at 40 mph the same distance of 40(15 hrs - time hrs). The distance is the same; therefore, set them equal.
60t = 40(15-t)
60t = 600 - 40t
100t = 600
t = 6 hrs for the 60 mph day.
15-t = 9 hours for the 40 mph day.
distance = 6 h x 60 mph = 360 miles.
distance = 9 h x 40 mph = 360 miles.
Given the figure below, find the values of x and z
Answer:
x = 2
z = 111°
Step-by-step explanation:
Angles having measures (7x + 55)° and (14x + 41)° are the vertically opposite angles.
Therefore, both the angles will measure the same.
(7x + 55) = (14x + 41)
7x - 14x = 41 - 55
-7x = -14
x = 2
Measure of angle (7x + 55)° = 7(2) + 55
= 14 + 55
= 69°
Since, angles measuring 69° and z° are the linear pair of angles,
69° + z° = 180°
z = 180 - 69
z = 111°

Translate algebra expressions 2 less that 3 times z
Answer:
(3z) - 2
Step-by-step explanation:
Let's see an example:
(4x) - 6
This translates into 6 less than 4 times x
So... 2 less than 3 times z =
(3z) - 2
Answer:
Step-by-step explanation:
That would be "3z - 2:" 2 less than 3 times z.

Answer:
The description of a cross section of a right cylinder that is neither parallel nor perpendicular to the base is (an);
Ellipse
Step-by-step explanation:
The given question is presented as follows;
Which could be the description of a cross section of a right cylinder that is neither parallel nor perpendicular to the base;
The options obtained from an online source (PSD) are;
Circle
Ellipse
Rectangle
Triangle
The cross section of a right cylinder that is parallel to the base is in the shape of a circle
The cross section of a right cylinder that is perpendicular to the base of the cylinder is in the shape of a rectangle
The cross section of a right cylinder that is neither parallel nor perpendicular to the base of the cylinder is in the shape of an ellipse which is a form of an oval shape.
The graph of quadratic function p is shown on the grid. (-3, 3) (3, 3) If (x) = x and p(x) = 5(x) + n, what is the value of n?
Answer:
-6
Step-by-step explanation:
Sorry, no explaination, but it's correct (trust me)
The value of n for which the considered quadratic equation p(x) and k(x) are such that p(x) = k(x) + n is n = -6
What is vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
This graph goes through three points, (-3,3), (3,3), and (0,-6) (the last point is the vertex of the quadratic equation).
Let the function p(x) be:
[tex]p(x) = a(x-h)^2 + k[/tex]
Since the vertex lies on the point (h,k) = (0,-6), putting h = 0, and k = -6, we get:
[tex]p(x) = ax^2 -6[/tex]
Now, as this graph passes through (x,y) = (-3,3), putting x= -3, and y (output, or say p(x)) = 3, we get:
[tex]3 = a(-3)^2 - 6\\3 = 9a-6\\9a = 9\\a =1[/tex]
Thus, the function p(x) is:
[tex]p(x) = x^2 - 6[/tex]
But since [tex]k(x) = x^2[/tex], therefore,
[tex]p(x) = x^2 - 6 = k(x) - 6[/tex]
On comparison with p(x) = k(x) + n, we deduce that n = -6
Thus, the value of n for which the considered quadratic equation p(x) and k(x) are such that p(x) = k(x) + n is n = -6

Jorges car wash offers a weekend special on sand washes on cars, trucks , and SUVs. you can also chooses between wax, vacuum, and interior cleanings. how many different car washes can you make for the weekend?
Answer:
9 different car washes
Step-by-step explanation:
From the services that Jorge offers we can see that there are 3 options (wax, vacuum, and interior cleanings) on 3 different categories of vehicles (cars, trucks, and SUV). Therefore, in order to calculate the number of possible combinations or car washes that you can make, we need to multiply the number of options by the number of categories of vehicles. Like so...
3 * 3 = 9
Therefore, we can see that there are a total of 9 different car washes that you can make for the weekend.

44/15 converted into a mixed number (convert a fraction into a decimal before converting it into a mixed number)
Answer:
44/15 converted into a mixed number = 2(14/15)
Step-by-step explanation:
44/15 = 2.9333333...... = 2( 14/15)
so it is the number 2 and (0.93333)
Lets see how is the decimal is in fraction
0.93333 is a mixed recurrent number and in fraction is 14/15
14/15 = 0.93333.....
With recurring mixed decimal :
For the top part:
Take the non-repeating and the repeating(93) and subtract the non repeating(9)
93-9= 84
For the bottom part: for every repeating decimal,you put a 9 And for every non repeating decimal,you put a zero
so one 9 and one zero (90)
84/90 = 14/15 = 0.93333....
