Answer:
-7j-k-1
Step-by-step explanation:
a)
Check the picture below.
b)
volume wise, we know the smaller pyramid is 1/8 th of the whole pyramid, so the volume of the whole pyramid must be 8/8 th.
Now, if we take off 1/8 th of the volume of whole pyramid, what the whole pyramid is left with is 7/8 th of its total volume, and that 7/8 th is the truncated part, because the 1/8 we chopped off from it, is the volume of the tiny pyramid atop.
Now, what's the ratio of the tiny pyramid to the truncated bottom?
Step-by-step explanation:
Isolate the variable
10x - 7x = -20 - 8
3x = -28
x = -9.333333333333
Answer:
Response 1
Step-by-step explanation:
Response 1 is the only wording that is self-consistent. Response 1 is the appropriate response.
___
Response 2 argues about angles, then concludes sides are congruent. This makes no sense.
Response 3 identifies congruent segments, but they are not opposite sides. The conclusion is unsupported.
The final price (what it is selling for) is $796.40
The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.
We need to find the original price.
We write this as an equation
The original price *110% = final price
This is because the original price is itself (100%) added with 10%
Plug in the known final price
Original Price * 110% = 796.40
Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers.
Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)
110% = 1.1
So it is now
Original price *1.1 = 796.40
Divide both sides by 1.1 to isolate our unknown, the original price
Original price = $724
