What is 11/2 subtracted by 11/3
Answers
Answer:
11/6
Step-by-step explanation:
Answer:
1 5/6
First make it a mixed number. 11/2=5 1/2. 11/3=3 2/3. Next, you find the common denominator. 2 and 3 are both multiples of 6. You multiply 11x3=33, 2x3=6, 11x2=22 3x2= 6. Your new numbers are 5 3/6 and 3 4/6. Now you subtract. 5-3=2, but you have to regroup, so you end up with 1. 9/6-4/6=5/6. 1+5/6=1 5/6

Three vertices of parallelogram WZXY are W(-5, 2), X(2, 4) and Z(-7, -3). Find the coordinated of the vertex, Y.
Answers
Answer:
[tex]Y = (4,9)[/tex]
Step-by-step explanation:
Given
[tex]W(x_1,y_1) = (-5, 2)[/tex]
[tex]Z(x_4,y_4) = (-7, -3)[/tex]
[tex]X(x_2,y_2) = (2, 4)[/tex]
Required
Find Y
To do this, we make use of the mid-point formula
i.e.
[tex]M = \frac{1}{2}(x_n+x_m,y_n+y_m})[/tex]
WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:
[tex]M = \frac{1}{2}(-5+2,2+4)[/tex]
[tex]M = \frac{1}{2}(-3,6)[/tex]
The mid-point of ZY is:
[tex]M = \frac{1}{2}(-7+x,-3+y)[/tex]
Equate both values of M
[tex]\frac{1}{2}(-3,6) = \frac{1}{2}(-7+x,-3+y)[/tex]
Multiply both sides by 2
[tex](-3,6) = (-7+x,-3+y)[/tex]
By comparison:
[tex]-7 + x = -3[/tex]
[tex]-3 + y = 6[/tex]
[tex]-7 + x = -3[/tex]
[tex]x = 7 -3[/tex]
[tex]x = 4[/tex]
[tex]-3 + y = 6[/tex]
[tex]y = 6 +3[/tex]
[tex]y = 9[/tex]
Hence:
[tex]Y = (4,9)[/tex]

Can i have brainliest?
Answer:
528 Cubic Inches
Step-by-step explanation:
The first thing you would do is, since the equation states that the total height of the bench is 8 inches, is place 4 as the height of the rectangular prism piece of the bench. Next you would use of the dimensions of each of pieces of the bench to calculate the area of each piece respectively using the equation l*w*h. The equations are 4*4*25 which equals 400, 4*4*4 which equals 64, and 4*4*4 which equals 64. Next, you would add them all together which gives you a grand total of 528 cubic inches.

How do you solve this equation
2x+5y=-2
-2x-7y=6
Answers
For this system of equations, we can use the elimination method, where two variables from both equations will cancel our (in this case, 2x and -2x.
Adding the equations gives us -2y=4, where solving for y gives us -2.
Plugging -2 into any of the two equations and solving for x will result in x=4.

Answers
Answer:
After 5 hours, the number of bacteria will be 1024
Step-by-step explanation:
1 times 4 = 4
4 times 4 = 16
16 times 4 = 64
64 times 4 = 256
256 times 4 = 1024
It will take around 5 hours to exceed 1000
