answer:
so the basic formula to find volume in shapes would be length × width × height.
here is a example : ( i cant really make the shape 3D so lets just say it is )

and because i cant make the shape 3D, the width will be 2
all you really need to do is multiply all of them together, for smaller numbers you shouldn't have to really use your calculator ( if you have a pretty good memory of your times tables then you shouldn't have to as least ) but with bigger numbers then i would recommend using your calculator if your teacher does lets you
5 * 3 * 2
= 30 units !

I think domt know
Which of these systems of equations would be best solved using the subtraction method?
I. 2x−7y+3y = 4 −6x−4y = −52
II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52
Answer:
Step-by-step explanation:
1. x+2y=6 or x=6-2y
3x-2y=2
3(6-2y)-2y=2
18-6y-2y=2
18-8y=2
-8y=-18+2
-8y=-16
y=-16/-8
y=2 ans.
x+2*2=6
x+4=6
x=6-4=2 ans.
Proof:
3*2-2*2=2
6-4=2
2=2
I leave the rest for you to practice with.
3. 4x+y=7
2x+5y=-1
5. 3x+2y=-2
6x-y=6
Solve the system using the elimination method. Show all your steps.
7. -3x+3y=3
3x+y=9 add.
---------------------------------
4y=12
y=12/4
y=3 ans.
3x+3=9
3x=9-3
3x=6
x=6/3
x=2 ans.
Proof:
-3*2+3*3=3
-6+9=3
3=3
I'll leave the rest for practice.
9. -5x+12y=20
x-2y=-6
11. 3x+2y=1
4x+ 6y= 7
In the equation x + y = 8, find the value of x if y = 3
3
5
7
11
Answer:
11
Step-by-step explanation:
x+y=8 y=3
x+3=8
-3 -3
x=11
Answer:
substitute y in the equation
x+3=8
then we solve for x
transpose 3 to the right 8-3=5so therefore x=5

If John can paint half of a room in two-thirds of an hour, what part of the room can he paint in a full hour?
Use the table at the right. What part of the room will John paint in one hour?
Answer:
Answer: 0.75(3/4) part of the room
Step-by-step explanation:
Answer:
0.75(3/4) part of the room
Step-by-step explanation:
if he takes 2/3 hours to paint 0.5 room
then he will take 1 hour to paint x
cross multiply we have
x= 0.5/2/3
x=0.5*3/2
x= 1.5/2
x=0.75 part of the room
75/100= 15/20=3/4 part
The tree diagram shows the sample space of two-digit numbers that can be created using the digits 9,2 1, and 8. What is the probability of choosing a number from the sample space that contains both 2 and 8?
Answer:
Given : the sample space of two-digit numbers that can be created using the digits 9,7,1, and 8.
To Find : probability of choosing a number from the sample space that contains both 7 and 8.
Solution:
TREE DIAGRAM
9 7 1 8
↓ ↓ ↓ ↓
------------------- ---------------- ----------------- ---------------
↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
9 7 1 8 9 7 1 8 9 7 1 8 9 7 1 8
Total Sample space = 16
Contains both 7 and 8
is ( 7 , 8) or ( 8 , 7)
Hence probability of choosing a number from the sample space that contains both 7 and 8. = 2/16
= 1/8
= 12.5 %

Evaluate the given expression when x = 3.
Enter the number only.
Answer:
50
Step-by-step explanation:
If x=3 then x^3 would be 3 with the exponent of 3. It would look like 3x3x3=27
6x would be 6 times 3 which is 18.
Then you have just an extra 5.
Then add them all together. 27+18+5=50.
Therefore, your answer is 50.

6) Convert mixed fraction to improper fraction and then plugin the values in the formula.
[tex]l= 3\frac{1}{3} yard=\frac{10}{3}\\\\w = 1\frac{5}{9} yard=\frac{14}{9}\\\\h =2\frac{1}{4} yard=\frac{9}{4}\\\\Volume of wood shed = l * w *h\\\\= \frac{10}{3}*\frac{14}{9}*\frac{9}{4}\\\\= \frac{5}{3}*\frac{7}{1}*\frac{1}{1}\\\\=\frac{5*7}{3}\\\\=\frac{35}{3}\\\\=11\frac{2}{3} cubic yard[/tex]
b) 10 cubic yard is less than 11 2/3 cubic yard. So, it will fit in the wood shed.
7) Right side rectangular prism:
l = 16 in
w = 5 in
h = 20 - 14 = 6 in
Volume 1 = 16 * 5 * 6 = 480 cubic inches
Left side rectangular prism:
l = 9 in
w = 5 in
h =14 in
Volume 2 = 9 * 5 * 14 = 630 cubic in
Volume of composite solid = 480 + 630 = 1110 cubic inches

Describe, step-by-step how to find the slope of a line through two points
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
The equation used to calculate the slope from two points is: m= y2 - y1 / x2 - x1
Example
Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?
Step One: Identify two points on the line.
In this example we are given two points, (15, 8) and (10, 7), on a straight line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).
Step Three: Use the equation to calculate slope.
Once we've completed step 2, we are ready to calculate the slope using the equation for a slope:
