Answer:
4 hours it will take for them to be equal.
Step-by-step explanation:
every hour Umpt collects 4
every hour Yoy loses 1,
54 + 4 = 58 +4 = 62 + 4 = 66 + 4 = 70
74 - 1 = 73 - 1 = 72 - 1 = 71 - 1 = 70
Answer:
L = 97, w = 27
Step-by-step explanation:
The perimeter formula is P = 2L + 2w. We have too many unknowns simply to plug in, so we have to find a way to identify one in terms of the other. The statement is that the length is 16 feet more than 3 times the width, so the length is in terms of the width and can be identified as
L = 3w + 16
and the width, then, is just w. Now we can fill in those 2 values, both in terms of w, and set it to equal the perimeter value we were given of 248:
2(3w + 16) + 2w = 248 and
6w + 32 + 2w = 248 and
8w + 32 = 248 and
8w = 216 so
w = 27
That means that the width is 27. Use that value of w now to find the length where
L = 3w + 16.
L = 3(27) + 16 and
L = 97
Answer:
Its D
Step-by-step explanation:
To be able to answer this item, one simply needs to find the square root of 56. Using the calculator, the square root of 56 is approximately equal to 7.48. Thus, the answer to the item are 7 and 8.
Another approach to answering this item is that we get familiar with the perfect squares there is under 100. The nearest perfect squares to 56 are 49 and 64. 49 is the square of 7 and 64 is the square of 8. Thus, the answers to the item item are 7 and 8.
Answer:

Step-by-step explanation:
the actual way of writing sin inverse is arcsine, not sin⁻¹
since the output of sin is from -1 to 1, the domain of arsince is from -1 to 1. This is different than 1/sin(x), whose domain is all real numbers. we now write sin⁻¹ to fit it on the tiny buttons on our calculators
