Answer:-1/4
Step-by-step explanation:
Take the negative of the reciprocal for perpendicular lines. In the case of no slope (y=number) replace y with x
Answer:
Step-by-step explanation:2+2=4
Answer:
-7
Step-by-step explanation:
First, we know that we are solving for x so what we need to do is to find out what times -5=35.
We know that
-5x7=-35
So we know our answer cant be positive 7, which means we need the opposite of 7 which is -7.
And:
-5x-7=35
This makes the equation true:
Hence, the correct answer is -7
4/5 of 80 is 64
99-64=35
35/5=7
7x8=56
Answer is 56
Lets divide this prism into two parts. The bottom part has dimensions of 15mm length x 5mm width x 7mm height.
The bottom is 15x5x7 = 525 cubic mm.
The top part has dimensions of 9mm length (I got this by subtracting the 3mm on each side that the top is shorter than the bottom.. 15-3x2) x 5mm width x 3mm height.
The top is 9x5x3 = 135 cubic mm.
Added together ... 525 + 135 = 660 cubic mm = the total area of the prism.
Hope this helps
