Answer:
80 cm cubed
Step-by-step explanation:
The volume of a rectangular pyramid is denoted by the following: , where B is the base area and h is the height.
Here, we are given that the base, which is a rectangle, dimensions are 8 cm by 6 cm. This means that the area is: A = lw = 8 * 6 = 48 cm squared. Hence, B = 48. We also know that h = 5. So, plug these into the equation:
Thus, the volume is 80 cm cubed.
Hope this helps!
130 - 40 = 90 (because you need to have soil to have flowers to grow)
90/6 = 15
So 15 flowers she can buy
Answer:
Step-by-step explanation:
<span>week 1 they sell X
week 2 they sell X+5
week three they sell 2(X + 5)
X + X + 5 + 2(X + 5) = 431
X + X + 5 + 2X + 10 = 431
4X + 15 = 431
4X = 416
X = 104
so
week 1 = 104
week 2 = 104 + 5 = 109
week three = (double week 2) = 218
and a quick check
218 + 109 + 104 = 431 --------- OK
--------------------------------------...
Julie = X
ted = 2X
mike = 3X
X + 2X + 3X = 210
6X = 210
X = 35
so Julie = 35
ted = 70
mike = 105
quick check
35 + 70 + 105 = 210 --------------- OK
--------------------------------------...
integer 1 = X
integer 2 = X + 1
integer 3 = X + 2
integer 4 = X + 3
X + X + 1 + X + 2 + X + 3 = 114
4X + 6 = 114
4X = 108
X = 27
quick check
27 + 28 + 29 + 30 = 114</span>
