Answer: 2n^2. let me know if you need the explanation :).
Step-by-step explanation:
It should be 0.08
Explanation: There are six ways to get a 7 and two ways to get an 11 on two dice, and so there are 36 – 8 = 28 ways to get anything else. Therefore, P(no 7 or 11) = P(always getting something else) = (28/36)10
Step-by-step explanation:
S=smaller number; L=larger number=3S
.
4S+5L=133
4S+5(3S)=133
4S+15S=133
19S=133
S=7 ANSWER 1: The smaller number is 7.
.
L=3S=3(7)=21 ANSWER 2: The larger number is 21.
.
CHECK:
4S+5L=133
4(7)+5(21)=133
28+105=133
133=133
The point (-11,34) has the coordinates x = -11 and y = 34
The point (47,0) has the coordinates x = 47 and y = 0
Let's focus on just the x coordinates of each point for now. Those values are -11 and 47. Add them up to get -11+47 = 36. Then divide by two to end up with 36/2 = 18
The x coordinate of the midpoint is x = 18
Repeat those steps for the y coordinates. First add them up: 34+0 = 34. Then divide by two: 34/2 = 17
The y coordinate of the midpoint is y = 17
<h3>Therefore the midpoint is located at (x,y) = (18,17)</h3>
--------------------------
side note:
If you want, you can use the formulas
xm = (x1+x2)/2
ym = (y1+y2)/2
where (x1,y1) and (x2,y1) are the two endpoints and (xm, ym) is the midpoint. Though this method may be a bit confusing.
Answer:
The cost of hardbook is $9 and cost of paperback is $5.
Step-by-step explanation:
Let x be the price for hardback book and y be the price for paperback book.
Mr. Yamamoto purchased 42 new hardcover books and 64 new paperback books, which cost a total of $698.
We can write the equation as:
He also purchased 42 new hardcover books and 58 new paperback books, which cost a total of $668.
We can write the equation as:
We have to use the elimination method to solve the two equations.
We eliminate x by subtracting the two equations.
Thus, the cost of hardbook is $9 and cost of paperback is $5.
