108 divided by 72= $1.50 per bag
1.50 times 126= 84
84 minus 72= 12
then check work
84 times $1.50
Answer:
a and c
Step-by-step explanation:
The volume (V) of a cuboid is
V = lwh ( l is length, w is width, h is height )
The volume is given as 210 cm³
Check each of the dimensions given to determine which give the correct volume
a
V = 15 × 2 × 7 = 210 ← correct volume
b
V = 14 × 3 × 7 = 294 ← incorrect volume
c
V = 7 × 3 × 10 = 210 ← correct volume
Hence a and c could be the dimensions of the box
<h3>
Answer: -2, -2, -2, -2</h3>
Explanation:
If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.
As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).
Answer:
There are 81 numbers
Step-by-step explanation:
Imagine that you have 4 boxes (one for each digit). In each box, you only have 3 choices for what digit you will do. You have to multiply all of the options (3*3*3*3) and you get 81.
Answer:
angle A is 94
angle B is 86
Step-by-step explanation:
supplementary angles add up to 180°
(6x + 10) + (4x + 30) = 180
10x + 40 = 180
10x = 140
x = 14
A is 94
B is 86
