Answer:
4 bag's
Step-by-step explanation:
Given the bean bag made by beth is in the shape of cube with each side of the cube equal to 2 feet.
Now Also given that each bean bag holds 2 cubic feet of beans.
Let the number of bags of beans recquired are x
The total number of beans available are 2x cubic feet
Now the volume of the bean bag made by beth is
Volume =
Volume = 8 cubic feet
Now 8 = 2x
x = 4
Therefore the number of bag's of beans recquired are 4
The coordinates of image of vertex D after a reflection across the x-axis is (5, 3).
So he bought 12 CDs and DVDs (in total), CDs + DVDs = 12
Each cd is 2 and each cd is 3
Total spent = 31 (2*x + 3*y)
I call x cds and y dvds
x+y = 12
2x+3y = 31
Solve for y
Move x to the right with changed sign
y = 12-x (DVDs, you can also write x = 12-y)
And substitute 12-y in the equation
2x + 3(12-x) = 31
2x + 36 - 3x = 31
2x - 3x = 31 - 36
-x = -5
x = 5 (CDs)
To find DVDs let's rewrite y = 12-x
y = 12-5 = 7 (DVDs)
Hi there!
First, scientific notation is when you take a number like 15,000 or 0.0015 and turn it into a number that is less than 10 and greater than 1. What you do to make it that is you move that decimal point over to the left or right as needed. So for example, 15,000 would be 1.5 ×
and 0.0015 is 1.5 ×
.
So if one light year is 5.88 ×
mi. that is just the scientific notation for 5880000000000 mi.
So if you take 5880000000000 mi. and multiply it by 11 then you get 64680000000000
5880000000000 × 11 = 64680000000000 or 6.468 ×
So the answer would be
