Answer:
-18 if youre asking about simple subtraction
Step-by-step explanation:
Volume (of a cube) = l×w×h
5 is the length
4 is the width
2 is the height
Just multiply these and you get 40 cm^3.
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by
3 which gives you the next term
Answer:
B. Three bags
Step-by-step explanation:
For this problem you want to first find the area of the triangle so let's use the formula: 1/2*b*h. We can see in the picture that your base is 20m and your height is 6m so let's plug in your values to the equation and you'll get 1/2*6*20. Let's then multiply and we'll get 60.
The problem then states that one bag of topsoil is 20 square meters while our area of the triangle is 60sq. meters. Divide, 60/20=3 therefore you will need 3 bags of top soil for the entire triangular flower bed.
