The height of the tank must be at least 1 foot, or 12 inches. We know the floor area (which is length x width) must be at least 400 inches. Therefore these minimum dimensions already tell us that the minimum volume is 400 x 12 = 4800 cubic inches. Since we have a maximum of 5000 cubic inches, the volume must be within the range of 4800 - 5000 cubic inches.
We can set the height at exactly 1 ft (or 12 inches). Then we can select length and width that multiply to 400 square inches, for example, L = 40 inches and W = 10 in. This gives us a tank of dimensions 40 x 10 x 12 = 4800 cubic inches, which fits all the criteria.
Answer:section 1 you choose c)rhombus
And the last one is X
Step-by-step explanation:sorry i can't explain but we literally got the same thing to do and i passed but what i tell you is correct
If I'm interpreting this question correctly, then you want to know the tax per dollar. In order to find that, you need to find the percentage of $420 that equals $60. So,
420x = 60
x = 60/420
x = 0.1429 (rounded)
So, the tax rate would be this value multiplied by 100%.
0.1429 x 100% = 14.29%
Answer:
55%
Step-by-step explanation:
In this question, the scenario is that Ms Grant made a presentation to the company that made her pay rise from $18 an hour to $27.90 an hour. We are now asked to find the percentage increase.
Mathematically, to get this, all we need to do is to subtract the old value from the new value, divided by the new value and multiplied by 100%. What we are saying here is that:
(New value - old value)/old value * 100%
(27.90 - 18)/18 * 100%
9.9/18 * 100%
That equals 990/18 = 55%
This means Ms Grant’s pay increased by 55%
