Step-by-step explanation:
Jose can read 7 pages of his book in 5minutes . At this rate how long will it take him to read the entire 175 page book.
Answer:
It will take 125 minutes or 2 hours and 5 minutes.
Step-by-step explanation:
We can use a proportion.
7 pages is to 5 minutes as 175 pages is to x minutes
7 : 5 = 175 : x
7/5 = 175/x
7x = 5 * 175
7x = 875
x = 125
It will take 125 minutes or 2 hours and 5 minutes.
The coordinates of the midpoint of line GH are M(−132,−6) and the coordinates of one endpoint are G(−4, 1). The coordinates of the other endpoint are
Answer:
Since, the coordinates of the midpoint of line GH are M(\frac{-13}{2}, -6)(
2
−13
,−6) .
The coordinates of endpoint G are (-4,1)
We have to determine the coordinates of endpoint H.
The midpoint of the line segment joining the points (x_1, y_1)(x
1
,y
1
) and (x_2, y_2)(x
2
,y
2
) is given by the formula (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})(
2
x
1
+x
2
,
2
y
1
+y
2
) .
Here, The endpoint G is (-4,1) So, x_1 = -4 , y_1=1x
1
=−4,y
1
=1
Let the endpoint H be (x_2,y_2)(x
2
,y
2
)
The midpoint coordinate M is (\frac{-13}{2}, -6)(
2
−13
,−6) .
So, \frac{-13}{2} = \frac{-4+x_2}{2}
2
−13
=
2
−4+x
2
{-13} = {-4+x_2}−13=−4+x
2
{-13}+4 = {x_2}−13+4=x
2
{x_2}=9x
2
=9
Now, -6 = \frac{1+y_2}{2}−6=
2
1+y
2
-12 = {1+y_2}−12=1+y
2
y_2= -13y
2
=−13
So, the other endpoint H is (-9,-13).

Factorise 7x² + 14xy - 21xyz (SHOW STEPS)
Answer:
[tex]7x(x+2y-3yz)[/tex]
Step-by-step explanation:
First we find the greatest common factor of the coefficients, 7, 14 and 21.
The greatest common factor is 7.
Factor 7 out and divide the terms by 7:
[tex]7x^2+14xy-21xyz=7(x^2+2xy-3xyz)[/tex]
-----------------------------------------------------
Next, we find the greatest common factor of [tex]x^2,xy[/tex] and [tex]xyz[/tex].
The greatest common factor is x.
Factor x out and divide the terms by x:
[tex]7(x^2+2xy-3xyz)=7x(x+2y-3yz)[/tex]

Answer:
angle xyb will measure 123 degrees.
Step-by-step explanation:
because we know that angle ayz is 57 degrees and angle xyz is 90, we find that angle xya measures 33 degrees by subtracting 57 from 90. then, we can find angle xyb by subtracting 33 from 180, getting 147 degrees. when we add 147, 33, and 57, we get 237 degrees. finally, we subtract 237 from 360 and get 123 degrees, our final angle. hope this helps:)

A college book store marks up the price that is pays the publisher for a book by 35%. If the selling price of a book is $56.00, how much did the bookstore pay for this book
Answer:
$41.48
Step-by-step explanation:
From the information given, you know that the price that the bookstore pays for a book is marked up 35% and that the selling price of a book is $56, so to be able to find the amount that the bookstore paid for a specific book, you can write the following equation:
x+0.35x=56, where x is the price the bookstore paid for the book.
Now you can solve for x:
1.35x=56
x=56/1.35
x=41.48
According to this, the bookstore paid $41.48 for this book.
